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

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.

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?

 

Thank you,

Leonid
