Hi Anna, I’d like to create process with particular size of CSpace and VSpace. CSpace size is defined in ‘config’ structure, I can set config.one_level_cspace_size_bits member. I am not sure how to set up VSpace size through ‘reservations’ and ‘num_reservations’ values? Let’s say I need to give to new process 10Mb virtual space. static inline sel4utils_process_config_t process_config_create_vspace(sel4utils_process_config_t config, sel4utils_elf_region_t *reservations, int num_reservations) { config.create_vspace = true; config.reservations = reservations; config.num_reservations = num_reservations; return config; } Thank you, Leonid From: Anna.Lyons(a)data61.csiro.au &lt;Anna.Lyons(a)data61.csiro.au&gt; Sent: Wednesday, August 15, 2018 8:37 PM To: Leonid Meyerovich &lt;lmeyerovich(a)i-a-i.com&gt;om>; devel(a)sel4.systems Subject: Re: create process in seL4 Hi Leonid, I don't understand your first question, which untyped are you wanting to adjust the size of? As for the second question, you can take a look at the sel4bench project, where all created processes use the same function to get a working allocator through the libsel4benchsupport library bundled with the project [1]. We're aware we need more tutorials and I'll add this to the list of desired seL4 tutorials. Thanks Anna. ​ [1] https://github.com/seL4/sel4bench/blob/master/libsel4benchsupport/src/suppo… ________________________________ From: Devel <devel-bounces@sel4.systems<mailto:devel-bounces@sel4.systems>> on behalf of Leonid Meyerovich <lmeyerovich@i-a-i.com<mailto:lmeyerovich@i-a-i.com>> Sent: Thursday, 16 August 2018 6:43 AM To: devel@sel4.systems<mailto:devel@sel4.systems> Subject: [seL4] create process in seL4 Hello, Is there any way to define untyped size while creating process using library functions? process_config_default_simple(simple_t *simple, const char *image_name, uint8_t prio) sel4utils_configure_process_custom(sel4utils_process_t *process, vka_t *vka, vspace_t *spawner_vspace, sel4utils_process_config_t config) The second question is how to initialize allocator (probably I should use bootstrap_use_current_1level, but how where should I get parameters?) in created process to support memory allocation operations?
