Subject: [4.5-rc regression] drm radeon Tahiti_vce fails to load
Alex, the 4.5-rc 32-bit kernels seem to have a problem initializing VCE.
The drm.debug boot option does not show more info as to what the problem
is.
On 4.4 (tested with 4.4.1 and 4.4.2) kernels it is loading OK.
I have confirmed the regression on 4.5-rc2 and 4.5-rc4 kernels.
[ 1.051686] radeon 0000:01:00.0: Requesting firmware: radeon/TAHITI_vce.bin
[ 1.051856] radeon 0000:01:00.0: Direct firmware load for
radeon/TAHITI_vce.bin failed with error -2
[ 1.051858] radeon 0000:01:00.0: radeon_vce: Can't load firmware
"radeon/TAHITI_vce.bin"
You did not include the vce firmware image in your kernel image. Please make
sure to include the firmware image in your kernel image if you are building it
in or if you are using an initrd, please make sure the firmware image is in
your initrd.
Alex
You are right - somehow the TAHITI_vce.bin got omitted from the kernel's
.config.
The Radeon included firmware line is now close to 3400 long, and
growing... Will there be a better way to manage these firmware blobs (a
rhetorical question)...
Thanks, Woody
