Detailed Description

Process management.

Macro Definition Documentation

SYS_PROCESS_PARAM

#define SYS_PROCESS_PARAM	(		prio,
			stacksize
	)

Value:

sys_process_param_t __sys_process_param __attribute__((aligned(8), section(".sys_proc_param"), unused)) = { \
        sizeof(sys_process_param_t), \
        SYS_PROCESS_SPAWN_MAGIC, \
        SYS_PROCESS_SPAWN_VERSION_090, \
        SYS_PROCESS_SPAWN_FW_VERSION_192, \
        prio, \
        stacksize, \
        SYS_PROCESS_SPAWN_MALLOC_PAGE_SIZE_1M, \
        SYS_PROCESS_SPAWN_PPC_SEG_DEFAULT\
    };

Configure process priority and stack size.

Typically call this macro outside function declarations.

Parameters

prio	priority (1000 = normal)
stacksize	stack size

SYS_PROCESS_PARAM_FIXED

#define SYS_PROCESS_PARAM_FIXED	(		prio,
			stacksize
	)

Value:

sys_process_param_t __sys_process_param __attribute__((aligned(8), section(".sys_proc_param"), unused)) = { \
        sizeof(sys_process_param_t), \
        SYS_PROCESS_SPAWN_MAGIC, \
        SYS_PROCESS_SPAWN_VERSION_090, \
        SYS_PROCESS_SPAWN_FW_VERSION_192, \
        prio, \
        stacksize, \
        SYS_PROCESS_SPAWN_MALLOC_PAGE_SIZE_1M, \
        SYS_PROCESS_SPAWN_PPC_SEG_PRX \
    };

SYS_PROCESS_PARAM_OVLM

#define SYS_PROCESS_PARAM_OVLM	(		prio,
			stacksize
	)

Value:

sys_process_param_t __sys_process_param __attribute__((aligned(8), section(".sys_proc_param"), unused)) = { \
        sizeof(sys_process_param_t), \
        SYS_PROCESS_SPAWN_MAGIC, \
        SYS_PROCESS_SPAWN_VERSION_090, \
        SYS_PROCESS_SPAWN_FW_VERSION_192, \
        prio, \
        stacksize, \
        SYS_PROCESS_SPAWN_MALLOC_PAGE_SIZE_1M, \
        SYS_PROCESS_SPAWN_PPC_SEG_OVLM \
    };
