Hello,

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.

If you see such a message, the driver or component in general will not continue.
The specified memory for the driver seems to be too low, try to increase it. It should be something above 9.2M (7680 Byte * 1200 = 9.2 M + some memory for the driver). Maybe 10-11M should suffice.

This is a assertion in the seL4 kernel. Probably it complains about that region overlap due to following lines
Adding physical memory region 0x100000-0x1f800000 Adding physical memory region 0x0-0x1f800000
I'm not sure, whether here the Multiboot 2 information is incorrect or the parsing by the kernel is too strict. Here one would require some more investigation in the Multiboot 2 spec (overlapping regions are valid or not?) and on the target machine in grub2/uefi, potentially bender and the sel4 kernel.
Thanks for testing and the infos.
I tried your suggestion and increased the memory for the framebuffer.The UP board booted all the way to the graphical interface, very exciting! Unfortunately the usb keyboard and mouse do not work. The Minnowboard still does not give any graphical output. The logs for both are below.
I have found that on some hardware the OS does not know where to find the RSDP value when booting via multiboot and UEFI and as a result USB peripherals do not work. This is not just a problem with sel4 I have seen it with xen as well. That may be the problem here. I attempted to fix the problem by editing the sel4 source code. I added:
#define UPBOARD_RSDP 0x5B161000
to ./contrib/sel4-097171f475bff21223783e130445b9be6b3d1bb4/src/kernel/sel4/include/plat/pc99/plat/machine/acpi.h. Then I replaced the function acpi_get_rsdp in ./contrib/sel4-097171f475bff21223783e130445b9be6b3d1bb4/src/kernel/sel4/src/plat/pc99/machine/acpi.c with:
acpi_get_rsdp(void) { return (acpi_rsdp_t*)UPBOARD_RSDP; }
But either my intuition about the problem is wrong or I am attempting to fix it incorrectly. I get exactly the same logs with or without the above fixes.
Do you have any suggestions on the keyboard and mouse?

I tried your suggestion and increased the memory for the framebuffer.The UP board booted all the way to the graphical interface, very exciting!
nice.
Unfortunately the usb keyboard and mouse do not work. The Minnowboard still does not give any graphical output. The logs for both are below.
I have found that on some hardware the OS does not know where to find the RSDP value when booting via multiboot and UEFI and as a result USB peripherals do not work. This is not just a problem with sel4 I have seen it with xen as well. That may be the problem here. I attempted to fix the problem by editing the sel4 source code. I added:
#define UPBOARD_RSDP 0x5B161000
to ./contrib/sel4-097171f475bff21223783e130445b9be6b3d1bb4/src/kernel/sel4/include/plat/pc99/plat/machine/acpi.h. Then I replaced the function acpi_get_rsdp in ./contrib/sel4-097171f475bff21223783e130445b9be6b3d1bb4/src/kernel/sel4/src/plat/pc99/machine/acpi.c with:
acpi_get_rsdp(void) { return (acpi_rsdp_t*)UPBOARD_RSDP; }
But either my intuition about the problem is wrong or I am attempting to fix it incorrectly. I get exactly the same logs with or without the above fixes.
acpi_get_rsdp is not called for Multiboot2(MBI2)/UEFI case. The RSDP information is expected to be part of MBI2.
The function try_boot_sys_mbi2 in
contrib/sel4-097171f475bff21223783e130445b9be6b3d1bb4/src/kernel/sel4/src/arch/x86/kernel/boot_sys.c
looks up the information and copies it to boot_state.acpi_rsdp.
Do you have any suggestions on the keyboard and mouse?
Yes, if you look at the lines about the boot modules
boot module 'acpi_drv' (96740 bytes) ...
you will miss a line about the usb driver.
In the demo run scenario the usb driver is not started for x86, instead the ps2 driver is taken. You would need to adjust the demo scenario to use the usb driver instead of the ps2 driver. (Or at best use both drivers and add a input multiplexer, e.g. [0], which takes both drivers as input sources).
Beforehand you may just try the usb_hid [1] scenario to actual test whether usb in general work on your machine(s).

Hey Alexander,
Thanks to your suggestion I now have the UP board booting via UEFI and USB input is working as expected. Thanks for your help. I am happy to help test any UEFI modifications you make in future releases. For anyone who is interested in reproducing this I will summarize what I did to get a working demo built.
I created a build dir that specifies the sel4 kernel. This option is listed as deprecated but it still works.
$ ./tool/create_builddir sel4_x86_32 build_sel4
I modified the build.conf file to build a UEFI image rather than and iso for qemu and I enabled the libports and dde_linux repos. I pasted the full text of my build.conf below.
I then modified the demo.run file to: * remove ps2_drv * remove fb_drv * add fb_boot_drv * add usb_drv
The usb_drv sections were copied from repos/dde_linux/run/usb_hid.run but I removed the portions that referred to capslock, numlock and scrlock as they were causing errors that interfered with the boot process. I pasted the full text of my modified demo.run below.
Then all I had to do was prepare the dde_linux port and build my image:
$ ./tool/ports/prepare_port dde_linux $ make run/demo

One more data point, ethernet also seems to be working. I compiled a UEFI image from the tcp_terminal example in the gems repo. I can now happily recommend the UP hardware (Atom) as an embedded platform for seL4 with driver support courtesy of Genode.
