Function Documentation

struct cvmx_sysinfo* cvmx_sysinfo_get ( void  )

read

This function returns the system/board information as obtained by the bootloader.

Returns Pointer to the boot information structure

This function returns the application information as obtained by the bootloader. This provides the core mask of the cores running the same application image, as well as the physical memory regions available to the core.

Returns Pointer to the boot information structure

int cvmx_sysinfo_minimal_initialize	(	void *	phy_mem_desc_ptr,
		uint16_t	board_type,
		uint8_t	board_rev_major,
		uint8_t	board_rev_minor,
		uint32_t	cpu_clock_hz
	)

This function is used in non-simple executive environments (such as Linux kernel, u-boot, etc.) to configure the minimal fields that are required to use simple executive files directly.

Locking (if required) must be handled outside of this function

: Pointer to global physical memory descriptor (bootmem descriptor) : Octeon board type enumeration

: Board major revision : Board minor revision : CPU clock freqency in hertz

Returns 0: Failure 1: success
