dmesg output and other supporting information

[AMD/ATI] RV710 [Radeon HD 4350/4550] on M5A97 PRO and AMD Phenom(tm) II X6
1100T Processor (16Gbyte RAM) fails to load RV710_uvd.bin at boot. I have found
that "request_firmware" call is returning -2 (ENOENT) though the correct file
is available in /lib/firmware/radeon. On further investigation this appears to
stem from "assign_firmware_buf" not having a buffer available (buf->size=0). I
have attached an instrumented dmesg (lines tagged with SMF), lspci and
/lib/firmware/radion listings for information. I am assuming that this video
card should support the UVD functionality.
Please advise.

regards

Stuart Foster

This isn't a bug, but a configuration error.

You compile the radeon module directly into the kernel, but don't include the
RV710_uvd.bin firmware into your kernel image. See CONFIG_EXTRA_FIRMWARE in
your kernel configuration for details.

Regards,
Christian.

Christian,

Thanks for the info, that has got me passed the firmware loading stage, I am
still a little confused has to the criterion for including firmware in the
kernel image, for example in this case radeon/R700_rlc.bin and
radeon/RV710_uvd.bin seem to be a "must include" where as  
radeon/RV710_pfp.bin and radeon/RV710_me.bin seem to be happy loaded from the
file system at boot time. Obviously early in the boot sequence there are less
resources to perform things like file loading but to me it seems some what
arbitrary, the documentation suggest to me that within certain constraints it
is a developers choice. What is your view ?

Thanks

Stuart Foster

No idea why your kernel ends up like it does, but the firmware isn't loaded
from the harddisk.

The RV710_me.bin and RV710_pfp.bin are definitely inside your kernel image,
take a look at your dmesg the disk is initialized why after the radeon module.

Looks like your distribution does something to get the RV710_me.bin and
RV710_pfp.bin into the kernel, otherwise I can't explain what happens here.

Christian.

Christian,

Ok its a mystery, I will dig deeper later, there are more interesting 
things to look at in the mean time.

thanks again.

Please try remaking your initial ramdisk.
