request_firmware_nowait - asynchronous version of request_firmware
2. SYNOPSIS ▲
int request_firmware_nowait(struct module * module , bool uevent , const char * name , struct device * device , gfp_t gfp , void * context , void (* cont ) (const struct firmware *fw, void *context));
3. ARGUMENTS ▲
module requesting the firmware
sends uevent to copy the firmware image if this flag is non-zero else the firmware copy must be done manually.
name of firmware file
device for which firmware is being loaded
will be passed over to cont, and fw may be NULL if firmware request fails.
function will be called asynchronously when the firmware request is over.
4. DESCRIPTION ▲
Caller must hold the reference count of device.
Asynchronous variant of request_firmware for user contexts: - sleep for as small periods as possible since it may increase kernel boot time of built-in device drivers requesting firmware in their ->probe methods, if gfp is GFP_KERNEL.
- canAqt sleep at all if gfp is GFP_ATOMIC.
