Kernel bisect log

I have a 2GB Radeon R7 260X (BONAIRE).

With kernel 4.7 and above, I was experiencing extremely slow performance. E=
ven
desktop animations on Ubuntu 16.04 w/ Unity desktop are extremely choppy,
probably about 10fps.

dmesg produces several instances of the following error message:
[drm:ci_dpm_set_power_state [radeon]] *ERROR* ci_upload_dpm_level_enable_ma=
sk
failed

I did a kernel bisect, and narrowed the problem to the following commit:
http://git.kerne=
l.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=3D7050c6ef5f=
0e9bc5e6bf9eb035320b70f731b919

The bisect log is attached.

It seems that the commit adds support for a new firmware file,
"bonaire_uvd.bin". If the driver fails in loading the new firmwar=
e file, it
falls back to the legacy file, "BONAIRE_uvd.bin".

To confirm that the issue is caused by the new firmware, I deleted
bonaire_uvd.bin, and performance is restored to normal with the latest stab=
le
kernel (4.9.0-rc7).

For what it's worth, here are the contents of
/sys/kernel/debug/dri/64/radeon_pm_info while idling on the Ubuntu desktop =
with
the new firmware:

uvd    disabled
vce    disabled
power level avg    sclk: 115774 mclk: 15000

And the old firmware:
uvd    disabled
vce    disabled
power level avg    sclk: 30248 mclk: 165000
