Is there a plan to add UEFI support in seL4 for x86 hardware in the near future? Newer x86 boards are frequently UEFI only. It is possible to get around the lack of UEFI support, as I have done with the UP board: https://up-community.org/wiki/Hardware_Specification but I am hitting problems which I will detail below. When I compile using ia32_debug_xml_defconfig and boot using the resulting images the board fails to find the RSDP location. To fix this I had to modify the source code a bit: * seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.h + #define UPBOARD_RSDP 0x5B161000 * seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.c - acpi->rsdp = acpi_sig_search(acpi, ACPI_SIG_RSDP, strlen(ACPI_SIG_RSDP), - (void *) BIOS_PADDR_START, (void *) BIOS_PADDR_END); + acpi->rsdp = (void *)UPBOARD_RSDP; * seL4test/kernel/src/plat/pc99/machine/acpi.c - for (addr = (char*)BIOS_PADDR_START; addr < (char*)BIOS_PADDR_END; addr += 16) { + for (addr = (char*)0; addr < (char*)PPTR_BASE; addr += 16) { It would be handy to have this as a kernel parameter to cover cases where it is not successfully discovered automatically. With these changes I can boot the board and several tests pass but then I get stuck on INTERRUPT0001 (Test interrupts with timer). I don't get a test failure or an error the board just sits and makes no more progress. Someone had that test fail in this post: https://sel4.systems/pipermail/devel/2017-February/001328.html and the first recommendation was to check if the irq of the timer was correctly found. I booted the board into linux to find the correct irq which was listed as 0 in /proc/interupts. I added a printf to handleInterrupt in the kernel source, recompiled and when I booted seL4 I found that the irq reported to handleInterrupt is 125 (which sel4 reports as the max interrupt value) every time that function is called. Adding this printf also showed me that when the test hangs the board hasn't crashed or locked up as calls to handleInterrupt are made continuously. At this point I noticed that before any tests started to run several ACPI tables are not recognized: Parsing ACPI tables Skipping table FPDTD, unknown Skipping table FIDT<9c>, unknown Skipping table UEFIB, unknown Skipping table TPM24, unknown Skipping table LPIT^D^A, unknown Skipping table BCFG9^A, unknown Skipping table PRAM0, unknown Skipping table CSRTL^A, unknown Skipping table BCFG9^A, unknown Skipping table OEM0<84>, unknown Skipping table OEM1@, unknown Skipping table PIDVÜ, unknown Skipping table RSCI,, unknown Skipping table WDAT^D^A, unknown Warning: skipping table ACPI XSDT Maybe one or more of those tables needs to be loaded to handle interrupts properly. The LPIT table is conspicuous in the case of the timer test but I think other tests are likely to depend on the other tables.

Hi Edward, In the near future? Unfortunately not. UEFI support is definitely something that we talk about every so often, but just never makes it high enough up the priority list for us internally. A configuration option for overriding the RSDP search doesn't so too unreasonable in cases where there isn't a BIOS region to search. At least until we can retrieve the address from the UEFI runtime. It is entirely possible that any number of tables and initialization needs to happen before the timer, or other hardware, will work. Currently the ACPI tables here are just being used to find the base address of the HPET, and it is assumed that it is in a working state and no further setup needs to be done. As for the IRQ numbers in seL4 you are seeing the local CPU vector delivery number, not the source I/O APIC interrupt number or GSI. To determine the IRQ source you could check the x86KSIRQState for the local CPU vector (in this case 125), unpack the x86_irq_state_t type, and see where it came from. The user code though is first trying to use the HPET and then if it cannot find that (i.e. it's not in the ACPI tables) then it falls back to the PIT. If it finds a HPET then it will try and use FSB (i.e. MSI) delivery, and failing that fall back to I/O APIC delivery. If you want to work out which of these its using you could either infer from the x86KSIRQState as mentioned above or instrument https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c57b62ac3... and https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c57b62ac3... to see what exactly it is doing.

Hello, since last week we successful added UEFI support to Genode/seL4 for x86. In this course we extended the seL4 6.0 kernel (beside the NOVA kernel and our own kernel - Genode/hw) to be also a Multiboot2 (MBI2) kernel. The MBI2 specification [3] provides to the kernel the ACPI RSDP information, which was the main reason to add MBI2 support. Together with GRUB2 (as UEFI capable bootloader) we were able to get our setups running on various native x86 machines and on Qemu. Additionally we extended the 3 kernels to propagate the ACPI RSDP information further to the user-land, since there the ACPI driver also failed to lookup the ACPI RSDP information. The patch for the seL4 kernel are currently on our staging branch (our automatically tested branch) and will show up in the upcoming release next week eventually. Currently, the patches are tight to Genode, but I can open up a feature issue on seL4 github if you are fine with the general direction - so adding MBI2 support in general. Or you would rather go in another direction like writing an own UEFI boot loader, which maybe is more minimal compared to GRUB2 etc etc. I have to admit, that the code addition to the seL4 kernel is far from being optimal - amount of code because of redundant MBI 1 vs 2 code, correctness of code (I'm not super familiar with the internals of the seL4 kernel), missing framebuffer information etc - but this we may discuss in more detail on github, if wanted.

Hi Alex, I think this is a good direction to move in, and supporting MBI2 definitely makes sense. In an ideal world, yes we would try and cut out grub2 and be pure UEFI booted, but given current resources I cannot see that happening any time soon, and so I see no reason not to welcome MBI2 support. As you point out some of the code itself is not perfect, but what it's actually doing seems fairly simple and non-controversial to me. Quite possibly you did this just to get it working as a proof of concept, but I would discourage adding more architecture information to the raw seL4_Bootinfo (the archInfo word is an old hack), and instead use the additional headers (https://github.com/seL4/seL4/blob/master/libsel4/include/sel4/bootinfo_types...). Aside from that, as you say the code needs some deduplication etc, but I'm happy to continue on github and get this in.

Hello, I built Genode 17.08 with run option "image/uefi" and platform option "sel4_x86_32". I have tried booting the resulting image on a variety of machines but am not getting the behavior I expect. The machines I have tried are: * Up board (a Windows compatible Atom-based system) * Dell M3800 laptop * Dell Latitude 7280 laptop * HP ProLiant DL380 Gen9 Server * Dell Optoplex 990 * Asus P9X79 WS Motherboard with Intel Core i7-3930K The furthest I have gotten was on the UP board, which only supports UEFI boot: https://www.intel.com/content/www/us/en/support/emerging-technologies/intel-... I saw serial output but no graphical output (see below). The other machines I tried to boot on didn't even give me serial output. The serial output seems to indicate that an attempt to create a framebuffer failed. Is this the correct build procedure? What hardware have you used to test UEFI boot? Does the trace below suggest any experiments to try? ***************************************************************** WARNING: no console will be available to OS Bender: Hello World.

Hello,
since last week we successful added UEFI support to Genode/seL4 for x86.
In this course we extended the seL4 6.0 kernel (beside the NOVA kernel and our own kernel - Genode/hw) to be also a Multiboot2 (MBI2) kernel. The MBI2 specification [3] provides to the kernel the ACPI RSDP information, which was the main reason to add MBI2 support. Together with GRUB2 (as UEFI capable bootloader) we were able to get our setups running on various native x86 machines and on Qemu.
Additionally we extended the 3 kernels to propagate the ACPI RSDP information further to the user-land, since there the ACPI driver also failed to lookup the ACPI RSDP information.
The patch for the seL4 kernel are currently on our staging branch (our automatically tested branch) and will show up in the upcoming release next week eventually.
Currently, the patches are tight to Genode, but I can open up a feature issue on seL4 github if you are fine with the general direction - so adding MBI2 support in general. Or you would rather go in another direction like writing an own UEFI boot loader, which maybe is more minimal compared to GRUB2 etc etc.
I have to admit, that the code addition to the seL4 kernel is far from being optimal - amount of code because of redundant MBI 1 vs 2 code, correctness of code (I'm not super familiar with the internals of the seL4 kernel), missing framebuffer information etc - but this we may discuss in more detail on github, if wanted.
Cheers,
Alex.

Hi Edward,
In the near future? Unfortunately not. UEFI support is definitely something that we talk about every so often, but just never makes it high enough up the priority list for us internally.
A configuration option for overriding the RSDP search doesn't so too unreasonable in cases where there isn't a BIOS region to search. At least until we can retrieve the address from the UEFI runtime.
It is entirely possible that any number of tables and initialization needs to happen before the timer, or other hardware, will work. Currently the ACPI tables here are just being used to find the base address of the HPET, and it is assumed that it is in a working state and no further setup needs to be done.
As for the IRQ numbers in seL4 you are seeing the local CPU vector delivery number, not the source I/O APIC interrupt number or GSI. To determine the IRQ source you could check the x86KSIRQState for the local CPU vector (in this case 125), unpack the x86_irq_state_t type, and see where it came from.
The user code though is first trying to use the HPET and then if it cannot find that (i.e. it's not in the ACPI tables) then it falls back to the PIT. If it finds a HPET then it will try and use FSB (i.e. MSI) delivery, and failing that fall back to I/O APIC delivery. If you want to work out which of these its using you could either infer from the x86KSIRQState as mentioned above or instrument https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c57b62ac3... and https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c57b62ac3... to see what exactly it is doing.

Is there a plan to add UEFI support in seL4 for x86 hardware in the near future? Newer x86 boards are frequently UEFI only. It is possible to get around the lack of UEFI support, as I have done with the UP board:
https://up-community.org/wiki/Hardware_Specification
but I am hitting problems which I will detail below.
When I compile using ia32_debug_xml_defconfig and boot using the resulting images the board fails to find the RSDP location. To fix this I had to modify the source code a bit:
* seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.h
+ #define UPBOARD_RSDP 0x5B161000
* seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.c
- acpi->rsdp = acpi_sig_search(acpi, ACPI_SIG_RSDP, strlen(ACPI_SIG_RSDP), - (void *) BIOS_PADDR_START, (void *) BIOS_PADDR_END); + acpi->rsdp = (void *)UPBOARD_RSDP;
* seL4test/kernel/src/plat/pc99/machine/acpi.c
- for (addr = (char*)BIOS_PADDR_START; addr < (char*)BIOS_PADDR_END; addr += 16) { + for (addr = (char*)0; addr < (char*)PPTR_BASE; addr += 16) {
It would be handy to have this as a kernel parameter to cover cases where it is not successfully discovered automatically. With these changes I can boot the board and several tests pass but then I get stuck on INTERRUPT0001 (Test interrupts with timer). I don't get a test failure or an error the board just sits and makes no more progress. Someone had that test fail in this post:
https://sel4.systems/pipermail/devel/2017-February/001328.html
and the first recommendation was to check if the irq of the timer was correctly found. I booted the board into linux to find the correct irq which was listed as 0 in /proc/interupts. I added a printf to handleInterrupt in the kernel source, recompiled and when I booted seL4 I found that the irq reported to handleInterrupt is 125 (which sel4 reports as the max interrupt value) every time that function is called. Adding this printf also showed me that when the test hangs the board hasn't crashed or locked up as calls to handleInterrupt are made continuously.
At this point I noticed that before any tests started to run several ACPI tables are not recognized:
Parsing ACPI tables Skipping table FPDTD, unknown Skipping table FIDT<9c>, unknown Skipping table UEFIB, unknown Skipping table TPM24, unknown Skipping table LPIT^D^A, unknown Skipping table BCFG9^A, unknown Skipping table PRAM0, unknown Skipping table CSRTL^A, unknown Skipping table BCFG9^A, unknown Skipping table OEM0<84>, unknown Skipping table OEM1@, unknown Skipping table PIDVÜ, unknown Skipping table RSCI,, unknown Skipping table WDAT^D^A, unknown Warning: skipping table ACPI XSDT
Maybe one or more of those tables needs to be loaded to handle interrupts properly. The LPIT table is conspicuous in the case of the timer test but I think other tests are likely to depend on the other tables.
Any suggestions about porting this type of hardware?

I think that UEFI would involve the bootloader that the BIOS starts. I don't know if the bootstrap part of UEFI would be handled by seL4 itself or by something like grub/grub2. My wild-ass guess is that anything after seL4 takes over would be handled by a driver process that has the required capabilities to interface with the corresponding hardware.

Hello,
I built Genode 17.08 with run option "image/uefi" and platform option "sel4_x86_32". I have tried booting the resulting image on a variety of machines but am not getting the behavior I expect. The machines I have tried are:
* Up board (a Windows compatible Atom-based system) * Dell M3800 laptop * Dell Latitude 7280 laptop * HP ProLiant DL380 Gen9 Server * Dell Optoplex 990 * Asus P9X79 WS Motherboard with Intel Core i7-3930K
The furthest I have gotten was on the UP board, which only supports UEFI boot:
https://www.intel.com/content/www/us/en/support/emerging- technologies/intel-realsense-technology/000022699.html
I saw serial output but no graphical output (see below). The other machines I tried to boot on didn't even give me serial output. The serial output seems to indicate that an attempt to create a framebuffer failed.
Is this the correct build procedure? What hardware have you used to test UEFI boot? Does the trace below suggest any experiments to try?

Hello,
since last week we successful added UEFI support to Genode/seL4 for x86.
In this course we extended the seL4 6.0 kernel (beside the NOVA kernel and our own kernel - Genode/hw) to be also a Multiboot2 (MBI2) kernel. The MBI2 specification [3] provides to the kernel the ACPI RSDP information, which was the main reason to add MBI2 support. Together with GRUB2 (as UEFI capable bootloader) we were able to get our setups running on various native x86 machines and on Qemu.
Additionally we extended the 3 kernels to propagate the ACPI RSDP information further to the user-land, since there the ACPI driver also failed to lookup the ACPI RSDP information.
The patch for the seL4 kernel are currently on our staging branch (our automatically tested branch) and will show up in the upcoming release next week eventually.
Currently, the patches are tight to Genode, but I can open up a feature issue on seL4 github if you are fine with the general direction - so adding MBI2 support in general. Or you would rather go in another direction like writing an own UEFI boot loader, which maybe is more minimal compared to GRUB2 etc etc.
I have to admit, that the code addition to the seL4 kernel is far from being optimal - amount of code because of redundant MBI 1 vs 2 code, correctness of code (I'm not super familiar with the internals of the seL4 kernel), missing framebuffer information etc - but this we may discuss in more detail on github, if wanted.

Hi Edward,
In the near future? Unfortunately not. UEFI support is definitely something that we talk about every so often, but just never makes it high enough up the priority list for us internally.
A configuration option for overriding the RSDP search doesn't so too unreasonable in cases where there isn't a BIOS region to search. At least until we can retrieve the address from the UEFI runtime.
It is entirely possible that any number of tables and initialization needs to happen before the timer, or other hardware, will work. Currently the ACPI tables here are just being used to find the base address of the HPET, and it is assumed that it is in a working state and no further setup needs to be done.
As for the IRQ numbers in seL4 you are seeing the local CPU vector delivery number, not the source I/O APIC interrupt number or GSI. To determine the IRQ source you could check the x86KSIRQState for the local CPU vector (in this case 125), unpack the x86_irq_state_t type, and see where it came from.
The user code though is first trying to use the HPET and then if it cannot find that (i.e. it's not in the ACPI tables) then it falls back to the PIT. If it finds a HPET then it will try and use FSB (i.e. MSI) delivery, and failing that fall back to I/O APIC delivery. If you want to work out which of these its using you could either infer from the x86KSIRQState as mentioned above or instrument https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c5 7b62ac3621/libplatsupport/src/plat/pc99/ltimer.c#L225 and https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c5 7b62ac3621/libplatsupport/src/plat/pc99/ltimer.c#L306 to see what exactly it is doing.

Is there a plan to add UEFI support in seL4 for x86 hardware in the near future? Newer x86 boards are frequently UEFI only. It is possible to get around the lack of UEFI support, as I have done with the UP board:
https://up-community.org/wiki/Hardware_Specification
but I am hitting problems which I will detail below.
When I compile using ia32_debug_xml_defconfig and boot using the resulting images the board fails to find the RSDP location. To fix this I had to modify the source code a bit:
* seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.h
+ #define UPBOARD_RSDP 0x5B161000
* seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.c
- acpi->rsdp = acpi_sig_search(acpi, ACPI_SIG_RSDP, strlen(ACPI_SIG_RSDP), - (void *) BIOS_PADDR_START, (void *) BIOS_PADDR_END); + acpi->rsdp = (void *)UPBOARD_RSDP;
* seL4test/kernel/src/plat/pc99/machine/acpi.c
- for (addr = (char*)BIOS_PADDR_START; addr < (char*)BIOS_PADDR_END; addr += 16) { + for (addr = (char*)0; addr < (char*)PPTR_BASE; addr += 16) {
It would be handy to have this as a kernel parameter to cover cases where it is not successfully discovered automatically. With these changes I can boot the board and several tests pass but then I get stuck on INTERRUPT0001 (Test interrupts with timer). I don't get a test failure or an error the board just sits and makes no more progress. Someone had that test fail in this post:
https://sel4.systems/pipermail/devel/2017-February/001328.html
and the first recommendation was to check if the irq of the timer was correctly found. I booted the board into linux to find the correct irq which was listed as 0 in /proc/interupts. I added a printf to handleInterrupt in the kernel source, recompiled and when I booted seL4 I found that the irq reported to handleInterrupt is 125 (which sel4 reports as the max interrupt value) every time that function is called. Adding this printf also showed me that when the test hangs the board hasn't crashed or locked up as calls to handleInterrupt are made continuously.
At this point I noticed that before any tests started to run several ACPI tables are not recognized:
Parsing ACPI tables Skipping table FPDTD, unknown Skipping table FIDT<9c>, unknown Skipping table UEFIB, unknown Skipping table TPM24, unknown Skipping table LPIT^D^A, unknown Skipping table BCFG9^A, unknown Skipping table PRAM0, unknown Skipping table CSRTL^A, unknown Skipping table BCFG9^A, unknown Skipping table OEM0<84>, unknown Skipping table OEM1@, unknown Skipping table PIDVÜ, unknown Skipping table RSCI,, unknown Skipping table WDAT^D^A, unknown Warning: skipping table ACPI XSDT
Maybe one or more of those tables needs to be loaded to handle interrupts properly. The LPIT table is conspicuous in the case of the timer test but I think other tests are likely to depend on the other tables.
Any suggestions about porting this type of hardware?

I think that UEFI would involve the bootloader that the BIOS starts. I don't know if the bootstrap part of UEFI would be handled by seL4 itself or by something like grub/grub2. My wild-ass guess is that anything after seL4 takes over would be handled by a driver process that has the required capabilities to interface with the corresponding hardware.
Hello, I answered the question on the Genode mailing list. (https://sourceforge.net/p/genode/mailman/message/36060224) Just in short: On Genode we have 3 framebuffer options: fb_drv - using VESA BIOS to initialize the graphic device fb_boot_drv - reusing a already initialized graphic card (e.g. by UEFI and Grub2) intel_fb_drv - native graphic driver for Intel embedded graphic devices With UEFI boot, only the Intel driver will work for Genode/seL4, if you have the right hardware. The fb_drv is not known to work in UEFI mode (but does in BIOS/legacy mode). The fb_boot_drv component could work with seL4 in UEFI mode (it does with Genode/NOVA), but unfortunately the information about the framebuffer location, size, color depth etc. are not propagated through the seL4 kernel to the roottask (and from there to the fb_boot_drv component).

Hello,
I built Genode 17.08 with run option "image/uefi" and platform option "sel4_x86_32". I have tried booting the resulting image on a variety of machines but am not getting the behavior I expect. The machines I have tried are:
* Up board (a Windows compatible Atom-based system) * Dell M3800 laptop * Dell Latitude 7280 laptop * HP ProLiant DL380 Gen9 Server * Dell Optoplex 990 * Asus P9X79 WS Motherboard with Intel Core i7-3930K
The furthest I have gotten was on the UP board, which only supports UEFI boot:
https://www.intel.com/content/www/us/en/support/emerging-technologies/intel-...
I saw serial output but no graphical output (see below). The other machines I tried to boot on didn't even give me serial output. The serial output seems to indicate that an attempt to create a framebuffer failed.
Is this the correct build procedure? What hardware have you used to test UEFI boot? Does the trace below suggest any experiments to try?

Hello,
since last week we successful added UEFI support to Genode/seL4 for x86.
In this course we extended the seL4 6.0 kernel (beside the NOVA kernel and our own kernel - Genode/hw) to be also a Multiboot2 (MBI2) kernel. The MBI2 specification [3] provides to the kernel the ACPI RSDP information, which was the main reason to add MBI2 support. Together with GRUB2 (as UEFI capable bootloader) we were able to get our setups running on various native x86 machines and on Qemu.
Additionally we extended the 3 kernels to propagate the ACPI RSDP information further to the user-land, since there the ACPI driver also failed to lookup the ACPI RSDP information.
The patch for the seL4 kernel are currently on our staging branch (our automatically tested branch) and will show up in the upcoming release next week eventually.
Currently, the patches are tight to Genode, but I can open up a feature issue on seL4 github if you are fine with the general direction - so adding MBI2 support in general. Or you would rather go in another direction like writing an own UEFI boot loader, which maybe is more minimal compared to GRUB2 etc etc.
I have to admit, that the code addition to the seL4 kernel is far from being optimal - amount of code because of redundant MBI 1 vs 2 code, correctness of code (I'm not super familiar with the internals of the seL4 kernel), missing framebuffer information etc - but this we may discuss in more detail on github, if wanted.
Cheers,
Alex.

Hi Edward,
In the near future? Unfortunately not. UEFI support is definitely something that we talk about every so often, but just never makes it high enough up the priority list for us internally.
A configuration option for overriding the RSDP search doesn't so too unreasonable in cases where there isn't a BIOS region to search. At least until we can retrieve the address from the UEFI runtime.
It is entirely possible that any number of tables and initialization needs to happen before the timer, or other hardware, will work. Currently the ACPI tables here are just being used to find the base address of the HPET, and it is assumed that it is in a working state and no further setup needs to be done.
As for the IRQ numbers in seL4 you are seeing the local CPU vector delivery number, not the source I/O APIC interrupt number or GSI. To determine the IRQ source you could check the x86KSIRQState for the local CPU vector (in this case 125), unpack the x86_irq_state_t type, and see where it came from.
The user code though is first trying to use the HPET and then if it cannot find that (i.e. it's not in the ACPI tables) then it falls back to the PIT. If it finds a HPET then it will try and use FSB (i.e. MSI) delivery, and failing that fall back to I/O APIC delivery. If you want to work out which of these its using you could either infer from the x86KSIRQState as mentioned above or instrument https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c57b62ac3... and https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c57b62ac3... to see what exactly it is doing.

Is there a plan to add UEFI support in seL4 for x86 hardware in the near future? Newer x86 boards are frequently UEFI only. It is possible to get around the lack of UEFI support, as I have done with the UP board:
https://up-community.org/wiki/Hardware_Specification
but I am hitting problems which I will detail below.
When I compile using ia32_debug_xml_defconfig and boot using the resulting images the board fails to find the RSDP location. To fix this I had to modify the source code a bit:
* seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.h
+ #define UPBOARD_RSDP 0x5B161000
* seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.c
- acpi->rsdp = acpi_sig_search(acpi, ACPI_SIG_RSDP, strlen(ACPI_SIG_RSDP), - (void *) BIOS_PADDR_START, (void *) BIOS_PADDR_END); + acpi->rsdp = (void *)UPBOARD_RSDP;
* seL4test/kernel/src/plat/pc99/machine/acpi.c
- for (addr = (char*)BIOS_PADDR_START; addr < (char*)BIOS_PADDR_END; addr += 16) { + for (addr = (char*)0; addr < (char*)PPTR_BASE; addr += 16) {
It would be handy to have this as a kernel parameter to cover cases where it is not successfully discovered automatically. With these changes I can boot the board and several tests pass but then I get stuck on INTERRUPT0001 (Test interrupts with timer). I don't get a test failure or an error the board just sits and makes no more progress. Someone had that test fail in this post:
https://sel4.systems/pipermail/devel/2017-February/001328.html
and the first recommendation was to check if the irq of the timer was correctly found. I booted the board into linux to find the correct irq which was listed as 0 in /proc/interupts. I added a printf to handleInterrupt in the kernel source, recompiled and when I booted seL4 I found that the irq reported to handleInterrupt is 125 (which sel4 reports as the max interrupt value) every time that function is called. Adding this printf also showed me that when the test hangs the board hasn't crashed or locked up as calls to handleInterrupt are made continuously.
At this point I noticed that before any tests started to run several ACPI tables are not recognized:
Parsing ACPI tables Skipping table FPDTD, unknown Skipping table FIDT<9c>, unknown Skipping table UEFIB, unknown Skipping table TPM24, unknown Skipping table LPIT^D^A, unknown Skipping table BCFG9^A, unknown Skipping table PRAM0, unknown Skipping table CSRTL^A, unknown Skipping table BCFG9^A, unknown Skipping table OEM0<84>, unknown Skipping table OEM1@, unknown Skipping table PIDVÜ, unknown Skipping table RSCI,, unknown Skipping table WDAT^D^A, unknown Warning: skipping table ACPI XSDT
Maybe one or more of those tables needs to be loaded to handle interrupts properly. The LPIT table is conspicuous in the case of the timer test but I think other tests are likely to depend on the other tables.
Any suggestions about porting this type of hardware?

The fb_boot_drv component could work with seL4 in UEFI mode (it does with Genode/NOVA), but unfortunately the information about the framebuffer location, size, color depth etc. are not propagated through the seL4 kernel to the roottask (and from there to the fb_boot_drv component).
we changed the 'could work' to 'supposed to work' (for me personally 'does work') with today's Genode 17.11 release [0]. We extended the seL4 kernel to propagate the framebuffer information provided by GRUB2@UEFI via Multiboot2 to user-land. On Genode now our simple fb_boot_drv framebuffer driver can make use it. The seL4 kernel patch got already pushed for review and inclusion if appropriate [2]. Edward, maybe you can give the new Genode release a spin regarding seL4 & UEFI and graphical output on your available machines using the fb_boot_drv driver. Thanks, Alex.

Hello,
I built Genode 17.08 with run option "image/uefi" and platform option "sel4_x86_32". I have tried booting the resulting image on a variety of machines but am not getting the behavior I expect. The machines I have tried are:
* Up board (a Windows compatible Atom-based system) * Dell M3800 laptop * Dell Latitude 7280 laptop * HP ProLiant DL380 Gen9 Server * Dell Optoplex 990 * Asus P9X79 WS Motherboard with Intel Core i7-3930K
The furthest I have gotten was on the UP board, which only supports UEFI boot:
https://www.intel.com/content/www/us/en/support/emerging-technologies/intel-...
I saw serial output but no graphical output (see below). The other machines I tried to boot on didn't even give me serial output. The serial output seems to indicate that an attempt to create a framebuffer failed.
Is this the correct build procedure? What hardware have you used to test UEFI boot? Does the trace below suggest any experiments to try?

Hello,
since last week we successful added UEFI support to Genode/seL4 for x86.
In this course we extended the seL4 6.0 kernel (beside the NOVA kernel and our own kernel - Genode/hw) to be also a Multiboot2 (MBI2) kernel. The MBI2 specification [3] provides to the kernel the ACPI RSDP information, which was the main reason to add MBI2 support. Together with GRUB2 (as UEFI capable bootloader) we were able to get our setups running on various native x86 machines and on Qemu.
Additionally we extended the 3 kernels to propagate the ACPI RSDP information further to the user-land, since there the ACPI driver also failed to lookup the ACPI RSDP information.
The patch for the seL4 kernel are currently on our staging branch (our automatically tested branch) and will show up in the upcoming release next week eventually.
Currently, the patches are tight to Genode, but I can open up a feature issue on seL4 github if you are fine with the general direction - so adding MBI2 support in general. Or you would rather go in another direction like writing an own UEFI boot loader, which maybe is more minimal compared to GRUB2 etc etc.
I have to admit, that the code addition to the seL4 kernel is far from being optimal - amount of code because of redundant MBI 1 vs 2 code, correctness of code (I'm not super familiar with the internals of the seL4 kernel), missing framebuffer information etc - but this we may discuss in more detail on github, if wanted.
Cheers,
Alex.

Hi Edward,
In the near future? Unfortunately not. UEFI support is definitely something that we talk about every so often, but just never makes it high enough up the priority list for us internally.
A configuration option for overriding the RSDP search doesn't so too unreasonable in cases where there isn't a BIOS region to search. At least until we can retrieve the address from the UEFI runtime.
It is entirely possible that any number of tables and initialization needs to happen before the timer, or other hardware, will work. Currently the ACPI tables here are just being used to find the base address of the HPET, and it is assumed that it is in a working state and no further setup needs to be done.
As for the IRQ numbers in seL4 you are seeing the local CPU vector delivery number, not the source I/O APIC interrupt number or GSI. To determine the IRQ source you could check the x86KSIRQState for the local CPU vector (in this case 125), unpack the x86_irq_state_t type, and see where it came from.
The user code though is first trying to use the HPET and then if it cannot find that (i.e. it's not in the ACPI tables) then it falls back to the PIT. If it finds a HPET then it will try and use FSB (i.e. MSI) delivery, and failing that fall back to I/O APIC delivery. If you want to work out which of these its using you could either infer from the x86KSIRQState as mentioned above or instrument https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c57b62ac3... and https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c57b62ac3... to see what exactly it is doing.

Is there a plan to add UEFI support in seL4 for x86 hardware in the near future? Newer x86 boards are frequently UEFI only. It is possible to get around the lack of UEFI support, as I have done with the UP board:
https://up-community.org/wiki/Hardware_Specification
but I am hitting problems which I will detail below.
When I compile using ia32_debug_xml_defconfig and boot using the resulting images the board fails to find the RSDP location. To fix this I had to modify the source code a bit:
* seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.h
+ #define UPBOARD_RSDP 0x5B161000
* seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.c
- acpi->rsdp = acpi_sig_search(acpi, ACPI_SIG_RSDP, strlen(ACPI_SIG_RSDP), - (void *) BIOS_PADDR_START, (void *) BIOS_PADDR_END); + acpi->rsdp = (void *)UPBOARD_RSDP;
* seL4test/kernel/src/plat/pc99/machine/acpi.c
- for (addr = (char*)BIOS_PADDR_START; addr < (char*)BIOS_PADDR_END; addr += 16) { + for (addr = (char*)0; addr < (char*)PPTR_BASE; addr += 16) {
It would be handy to have this as a kernel parameter to cover cases where it is not successfully discovered automatically. With these changes I can boot the board and several tests pass but then I get stuck on INTERRUPT0001 (Test interrupts with timer). I don't get a test failure or an error the board just sits and makes no more progress. Someone had that test fail in this post:
https://sel4.systems/pipermail/devel/2017-February/001328.html
and the first recommendation was to check if the irq of the timer was correctly found. I booted the board into linux to find the correct irq which was listed as 0 in /proc/interupts. I added a printf to handleInterrupt in the kernel source, recompiled and when I booted seL4 I found that the irq reported to handleInterrupt is 125 (which sel4 reports as the max interrupt value) every time that function is called. Adding this printf also showed me that when the test hangs the board hasn't crashed or locked up as calls to handleInterrupt are made continuously.
At this point I noticed that before any tests started to run several ACPI tables are not recognized:
Parsing ACPI tables Skipping table FPDTD, unknown Skipping table FIDT<9c>, unknown Skipping table UEFIB, unknown Skipping table TPM24, unknown Skipping table LPIT^D^A, unknown Skipping table BCFG9^A, unknown Skipping table PRAM0, unknown Skipping table CSRTL^A, unknown Skipping table BCFG9^A, unknown Skipping table OEM0<84>, unknown Skipping table OEM1@, unknown Skipping table PIDVÜ, unknown Skipping table RSCI,, unknown Skipping table WDAT^D^A, unknown Warning: skipping table ACPI XSDT
Maybe one or more of those tables needs to be loaded to handle interrupts properly. The LPIT table is conspicuous in the case of the timer test but I think other tests are likely to depend on the other tables.
Any suggestions about porting this type of hardware?

I modified the demo.run file to use fb_boot_drv and built the uefi image. I tested it on an UP board, a Minnowboard Turbot, a Dell M3800 laptop, and a Dell Precision 5810 desktop. I was unable to get graphical output on any of them. I have pasted the logs for all (except the laptop which has no serial port) below. Perhaps I need to make more modifications to the run file than I did. Here is the diff of demo.run: 69c69 < <start name="fb_drv"> ---
<start name="fb_boot_drv"> 286c286 < lappend_if [have_spec framebuffer] boot_modules fb_drv
lappend_if [have_spec framebuffer] boot_modules fb_boot_drv
Do you have recommendations for building that might yield better results? What systems have you tested the new changes on? Thanks!

The fb_boot_drv component could work with seL4 in UEFI mode (it does with Genode/NOVA), but unfortunately the information about the framebuffer location, size, color depth etc. are not propagated through the seL4 kernel to the roottask (and from there to the fb_boot_drv component).
we changed the 'could work' to 'supposed to work' (for me personally 'does work') with today's Genode 17.11 release [0]. We extended the seL4 kernel to propagate the framebuffer information provided by GRUB2@UEFI via Multiboot2 to user-land. On Genode now our simple fb_boot_drv framebuffer driver can make use it. The seL4 kernel patch got already pushed for review and inclusion if appropriate [2].
Edward, maybe you can give the new Genode release a spin regarding seL4 & UEFI and graphical output on your available machines using the fb_boot_drv driver.
Thanks,
Alex.

Hello,
I built Genode 17.08 with run option "image/uefi" and platform option "sel4_x86_32". I have tried booting the resulting image on a variety of machines but am not getting the behavior I expect. The machines I have tried are:
* Up board (a Windows compatible Atom-based system) * Dell M3800 laptop * Dell Latitude 7280 laptop * HP ProLiant DL380 Gen9 Server * Dell Optoplex 990 * Asus P9X79 WS Motherboard with Intel Core i7-3930K
The furthest I have gotten was on the UP board, which only supports UEFI boot:
https://www.intel.com/content/www/us/en/support/emerging-technologies/intel-...
I saw serial output but no graphical output (see below). The other machines I tried to boot on didn't even give me serial output. The serial output seems to indicate that an attempt to create a framebuffer failed.
Is this the correct build procedure? What hardware have you used to test UEFI boot? Does the trace below suggest any experiments to try?

Hello,
since last week we successful added UEFI support to Genode/seL4 for x86.
In this course we extended the seL4 6.0 kernel (beside the NOVA kernel and our own kernel - Genode/hw) to be also a Multiboot2 (MBI2) kernel. The MBI2 specification [3] provides to the kernel the ACPI RSDP information, which was the main reason to add MBI2 support. Together with GRUB2 (as UEFI capable bootloader) we were able to get our setups running on various native x86 machines and on Qemu.
Additionally we extended the 3 kernels to propagate the ACPI RSDP information further to the user-land, since there the ACPI driver also failed to lookup the ACPI RSDP information.
The patch for the seL4 kernel are currently on our staging branch (our automatically tested branch) and will show up in the upcoming release next week eventually.
Currently, the patches are tight to Genode, but I can open up a feature issue on seL4 github if you are fine with the general direction - so adding MBI2 support in general. Or you would rather go in another direction like writing an own UEFI boot loader, which maybe is more minimal compared to GRUB2 etc etc.
I have to admit, that the code addition to the seL4 kernel is far from being optimal - amount of code because of redundant MBI 1 vs 2 code, correctness of code (I'm not super familiar with the internals of the seL4 kernel), missing framebuffer information etc - but this we may discuss in more detail on github, if wanted.
Cheers,
Alex.

Hi Edward,
In the near future? Unfortunately not. UEFI support is definitely something that we talk about every so often, but just never makes it high enough up the priority list for us internally.
A configuration option for overriding the RSDP search doesn't so too unreasonable in cases where there isn't a BIOS region to search. At least until we can retrieve the address from the UEFI runtime.
It is entirely possible that any number of tables and initialization needs to happen before the timer, or other hardware, will work. Currently the ACPI tables here are just being used to find the base address of the HPET, and it is assumed that it is in a working state and no further setup needs to be done.
As for the IRQ numbers in seL4 you are seeing the local CPU vector delivery number, not the source I/O APIC interrupt number or GSI. To determine the IRQ source you could check the x86KSIRQState for the local CPU vector (in this case 125), unpack the x86_irq_state_t type, and see where it came from.
The user code though is first trying to use the HPET and then if it cannot find that (i.e. it's not in the ACPI tables) then it falls back to the PIT. If it finds a HPET then it will try and use FSB (i.e. MSI) delivery, and failing that fall back to I/O APIC delivery. If you want to work out which of these its using you could either infer from the x86KSIRQState as mentioned above or instrument https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c57b62ac3... and https://github.com/seL4/util_libs/blob/fff76a36a02b8ccef3aa0b201751c57b62ac3... to see what exactly it is doing.

Is there a plan to add UEFI support in seL4 for x86 hardware in the near future? Newer x86 boards are frequently UEFI only. It is possible to get around the lack of UEFI support, as I have done with the UP board:
https://up-community.org/wiki/Hardware_Specification
but I am hitting problems which I will detail below.
When I compile using ia32_debug_xml_defconfig and boot using the resulting images the board fails to find the RSDP location. To fix this I had to modify the source code a bit:
* seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.h
+ #define UPBOARD_RSDP 0x5B161000
* seL4test/projects/util_libs/libplatsupport/src/plat/pc99/acpi/acpi.c
- acpi->rsdp = acpi_sig_search(acpi, ACPI_SIG_RSDP, strlen(ACPI_SIG_RSDP), - (void *) BIOS_PADDR_START, (void *) BIOS_PADDR_END); + acpi->rsdp = (void *)UPBOARD_RSDP;
* seL4test/kernel/src/plat/pc99/machine/acpi.c
- for (addr = (char*)BIOS_PADDR_START; addr < (char*)BIOS_PADDR_END; addr += 16) { + for (addr = (char*)0; addr < (char*)PPTR_BASE; addr += 16) {
It would be handy to have this as a kernel parameter to cover cases where it is not successfully discovered automatically. With these changes I can boot the board and several tests pass but then I get stuck on INTERRUPT0001 (Test interrupts with timer). I don't get a test failure or an error the board just sits and makes no more progress. Someone had that test fail in this post:
https://sel4.systems/pipermail/devel/2017-February/001328.html
and the first recommendation was to check if the irq of the timer was correctly found. I booted the board into linux to find the correct irq which was listed as 0 in /proc/interupts. I added a printf to handleInterrupt in the kernel source, recompiled and when I booted seL4 I found that the irq reported to handleInterrupt is 125 (which sel4 reports as the max interrupt value) every time that function is called. Adding this printf also showed me that when the test hangs the board hasn't crashed or locked up as calls to handleInterrupt are made continuously.
At this point I noticed that before any tests started to run several ACPI tables are not recognized:
Parsing ACPI tables Skipping table FPDTD, unknown Skipping table FIDT<9c>, unknown Skipping table UEFIB, unknown Skipping table TPM24, unknown Skipping table LPIT^D^A, unknown Skipping table BCFG9^A, unknown Skipping table PRAM0, unknown Skipping table CSRTL^A, unknown Skipping table BCFG9^A, unknown Skipping table OEM0<84>, unknown Skipping table OEM1@, unknown Skipping table PIDVÜ, unknown Skipping table RSCI,, unknown Skipping table WDAT^D^A, unknown Warning: skipping table ACPI XSDT
Maybe one or more of those tables needs to be loaded to handle interrupts properly. The LPIT table is conspicuous in the case of the timer test but I think other tests are likely to depend on the other tables.
Any suggestions about porting this type of hardware?
