Field Documentation

read

int(* nvram::read) (struct nvram *dev, uint8_t *dst, uint32_t src, size_t size)

Pointer to device-specific read function.

Copy data from system memory to NVRAM.

Parameters

[in]	dev	Pointer to NVRAM device descriptor
[out]	dst	Pointer to the first byte in the system memory address space
[in]	src	Starting address in the NVRAM device address space
[in]	len	Number of bytes to copy

Returns

Number of bytes read on success

<0 on errors

write

int(* nvram::write) (struct nvram *dev, const uint8_t *src, uint32_t dst, size_t size)

Pointer to device-specific write function.

Copy data from NVRAM to system memory.

Parameters

[in]	dev	Pointer to NVRAM device descriptor
[in]	src	Pointer to the first byte in the system memory address space
[in]	dst	Starting address in the NVRAM device address space
[in]	len	Number of bytes to copy

Returns

Number of bytes written on success

<0 on errors
