What I meant to keep well documented here was not just only the old firmware file name for the code, but also the module name firmware_class, and its respective sysfs class name which is registered. From what I recall testing, we could not rename the module now because of this. I believe it had to do with the modular case, given the sysfs class could still be registered. The fact that I forget the exact *issue* which prevented the module rename shows how important it is to document this. Folks 10 years from now may wonder why the hell that name stuck, and the point was to document that the *original* loader was the sysfs fallback mechanism. > as originally the only firmware loading mechanism available was the > mechanism we now use as a fallback mechanism. > > diff --git a/Documentation/driver-api/firmware/request_firmware.rst > b/Documentation/driver-api/firmware/request_firmware.rst > index cf4516dfbf96..8e34d29ea02d 100644 > --- a/Documentation/driver-api/firmware/request_firmware.rst > +++ b/Documentation/driver-api/firmware/request_firmware.rst > @@ -17,19 +17,24 @@ an error is returned. > > request_firmware > ---------------- > -.. kernel-doc:: drivers/base/firmware_class.c > +.. kernel-doc:: drivers/base/firmware_loader/main.c > :functions: request_firmware This is fixed on Hans de Goede's patch already merged on Greg's own tree. > request_firmware_direct > ----------------------- > -.. kernel-doc:: drivers/base/firmware_class.c > +.. kernel-doc:: drivers/base/firmware_loader/main.c > :functions: request_firmware_direct This is fixed on Hans de Goede's patch already merged on Greg's own tree. > request_firmware_into_buf > ------------------------- > -.. kernel-doc:: drivers/base/firmware_class.c > +.. kernel-doc:: drivers/base/firmware_loader/main.c > :functions: request_firmware_into_buf This is fixed on Hans de Goede's patch already merged on Greg's own tree. > +release_firmware > +---------------- > +.. kernel-doc:: drivers/base/firmware_loader/main.c > + :functions: release_firmware This is fixed on Hans de Goede's patch already merged on Greg's own tree. > + > Asynchronous firmware requests > ============================== > > @@ -41,7 +46,7 @@ in atomic contexts. > > request_firmware_nowait > ----------------------- > -.. kernel-doc:: drivers/base/firmware_class.c > +.. kernel-doc:: drivers/base/firmware_loader/main.c > :functions: request_firmware_nowait This is fixed on Hans de Goede's patch already merged on Greg's own tree. > > Special optimizations on reboot > @@ -54,8 +59,8 @@ this can be done with firmware_request_cache() insted of > requesting for the > firmare to be loaded. > > firmware_request_cache() > ------------------------ > -.. kernel-doc:: drivers/base/firmware_class.c > +------------------------ > +.. kernel-doc:: drivers/base/firmware_loader/main.c > :functions: firmware_request_cache This is fixed on Hans de Goede's patch already merged on Greg's own tree. > > request firmware API expected driver use > diff --git a/Documentation/driver-api/infrastructure.rst > b/Documentation/driver-api/infrastructure.rst > index 6d9ff316b608..bee1b9a1702f 100644 > --- a/Documentation/driver-api/infrastructure.rst > +++ b/Documentation/driver-api/infrastructure.rst > @@ -28,7 +28,7 @@ Device Drivers Base > .. kernel-doc:: drivers/base/node.c > :internal: > > -.. kernel-doc:: drivers/base/firmware_class.c > +.. kernel-doc:: drivers/base/firmware_loader/main.c This is fixed on Hans de Goede's patch already merged on Greg's own tree. > :export: > > .. kernel-doc:: drivers/base/transport_class.c > diff --git a/Documentation/power/suspend-and-cpuhotplug.txt > b/Documentation/power/suspend-and-cpuhotplug.txt > index 31abd04b9572..6f55eb960a6d 100644 > --- a/Documentation/power/suspend-and-cpuhotplug.txt > +++ b/Documentation/power/suspend-and-cpuhotplug.txt > @@ -168,7 +168,7 @@ update on the CPUs, as discussed below: > > [Please bear in mind that the kernel requests the microcode images from > userspace, using the request_firmware() function defined in > -drivers/base/firmware_class.c] > +drivers/base/firmware_loader/main.c] This is fixed on Hans de Goede's patch already merged on Greg's own tree.
