kernel log

Hello,

I'm using HP 1220tx Laptop with AMD HD8750M graphics card. Kernel keeps
complaining about setting UVD clocks and whole system stalls about 1 sec when
probing the UVD clocks. I've read the bug report here which reported exact same
problem for HD4570M: https://bugzilla.kernel.org/show_bug.cgi?id=60858 , but
the solution given doesn't help much...

According to that report, I did some research myself:
1. dump of the registers 0x0718, 0x071c and 0x0720
0x0718    0x00000031 (49)
0x071c    0xc080001c (-1065353188)
0x0720    0x3158680e (827877390)
2. fb_div=970296,vclk_div=3,dclk_div=4 at function si_set_uvd_clocks() and that
function failed the first radeon_uvd_send_upll_ctlreq() call with result -110.

Full dmesg attached.

You need this patch for UVD to work correctly on your chip:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5d029339bb8ce69aeb68280c3de67d3cea456146
Please make sure your kernel has it.

Seems that the kernel has already been patched.
It's the latest kernel from Arch Linux testing repository.

The strange thing is that the first clock setting works correctly (for booting
up the VCPU), but then we try it a second time (for the IB test) and that
fails.

No idea what's going wrong here, but the divider numbers look ok.

Does UVD works on Windows? Might be a hardware problem as well.

UVD works well on Windows.
When playing 720p video, cpu usage stays below 1%.

Could it be something wrong with Intel/AMD switchable graphics? I also have a
Intel HD4000 on my laptop.
