.SH "NAME"
request_firmware_nowait \- asynchronous version of request_firmware
.SH "SYNOPSIS"

.SH "ARGUMENTS"
.PP
\fImodule\fR
.RS 4
module requesting the firmware
.RE
.PP
\fIuevent\fR
.RS 4
sends uevent to copy the firmware image if this flag is non\-zero else the firmware copy must be done manually\&.
.RE
.PP
\fIname\fR
.RS 4
name of firmware file
.RE
.PP
\fIdevice\fR
.RS 4
device for which firmware is being loaded
.RE
.PP
\fIgfp\fR
.RS 4
allocation flags
.RE
.PP
\fIcontext\fR
.RS 4
will be passed over to
\fIcont\fR, and
\fIfw\fR
may be
\fBNULL\fR
if firmware request fails\&.
.RE
.PP
\fIcont\fR
.RS 4
function will be called asynchronously when the firmware request is over\&.
.RE
.SH "DESCRIPTION"
.PP
Caller must hold the reference count of
\fIdevice\fR\&.
.PP
Asynchronous variant of
\fBrequest_firmware\fR
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 \->\fBprobe\fR
methods, if
\fIgfp\fR
is GFP_KERNEL\&.
.PP
\- can\*(Aqt sleep at all if
\fIgfp\fR
is GFP_ATOMIC\&.
