https://bugzilla.kernel.org/show_bug.cgi?id=71141 Bug ID: 71141 Summary: [drm:radeon_uvd_send_upll_ctlreq] *ERROR* Timeout setting UVD clocks Product: Drivers Version: 2.5 Kernel Version: 3.13.5-1 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: mystery.wd@xxxxxxxxx Regression: No Created attachment 127361 --> https://bugzilla.kernel.org/attachment.cgi?id=127361&action=edit 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 are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
