NAME

6       request_firmware_nowait - asynchronous version of request_firmware
7

SYNOPSIS

9       int request_firmware_nowait(struct module * module, bool uevent,
10                                   const char * name, struct device * device,
11                                   gfp_t gfp, void * context,
12                                   void (*cont) (const struct firmware *fw, void *context));
13

ARGUMENTS

15       module
16           module requesting the firmware
17
18       uevent
19           sends uevent to copy the firmware image if this flag is non-zero
20           else the firmware copy must be done manually.
21
22       name
23           name of firmware file
24
25       device
26           device for which firmware is being loaded
27
28       gfp
29           allocation flags
30
31       context
32           will be passed over to cont, and fw may be NULL if firmware request
33           fails.
34
35       cont
36           function will be called asynchronously when the firmware request is
37           over.

DESCRIPTION

40       Caller must hold the reference count of device.
41
42       Asynchronous variant of request_firmware for user contexts: - sleep for
43       as small periods as possible since it may increase kernel boot time of
44       built-in device drivers requesting firmware in their ->probe methods,
45       if gfp is GFP_KERNEL.
46
47       - can't sleep at all if gfp is GFP_ATOMIC.
