drm/amdgpu/ci: disable mclk switching for high refresh rates (v2)

2017-06-14T13:07:38+00:00

commit 0a646f331db0eb9efc8d3a95a44872036d441d58 upstream. Even if the vblank period would allow it, it still seems to be problematic on some cards. v2: fix logic inversion (Nils) bug: https://bugs.freedesktop.org/show_bug.cgi?id=96868 Acked-by: Christian König Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amd/powerplay/smu7: add vblank check for mclk switching (v2)

2017-06-07T10:10:10+00:00

commit 09be4a5219610a6fae3215d4f51f948d6f5d2609 upstream. Check to make sure the vblank period is long enough to support mclk switching. v2: drop needless initial assignment (Nils) bug: https://bugs.freedesktop.org/show_bug.cgi?id=96868 Acked-by: Christian König Reviewed-by: Rex Zhu Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: Add missing lb_vblank_lead_lines setup to DCE-6 path.

2017-05-25T13:46:14+00:00

commit effaf848b957fbf72a3b6a1ad87f5e031eda0b75 upstream. This apparently got lost when implementing the new DCE-6 support and would cause failures in pageflip scheduling and timestamping. Signed-off-by: Mario Kleiner Cc: Alex Deucher Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: Avoid overflows/divide-by-zero in latency_watermark calculations.

2017-05-25T13:46:14+00:00

commit e190ed1ea7458e446230de4113cc5d53b8dc4ec8 upstream. At dot clocks > approx. 250 Mhz, some of these calcs will overflow and cause miscalculation of latency watermarks, and for some overflows also divide-by-zero driver crash ("divide error: 0000 [#1] PREEMPT SMP" in "dce_v10_0_latency_watermark+0x12d/0x190"). This zero-divide happened, e.g., on AMD Tonga Pro under DCE-10, on a Displayport panel when trying to set a video mode of 2560x1440 at 165 Hz vrefresh with a dot clock of 635.540 Mhz. Refine calculations to avoid the overflows. Tested for DCE-10 with R9 380 Tonga + ASUS ROG PG279 panel.

drm/amdgpu: Make display watermark calculations more accurate

2017-05-25T13:46:14+00:00

commit d63c277dc672e0c568481af043359420fa9d4736 upstream. Avoid big roundoff errors in scanline/hactive durations for high pixel clocks, especially for >= 500 Mhz, and thereby program more accurate display fifo watermarks. Implemented here for DCE 6,8,10,11. Successfully tested on DCE 10 with AMD R9 380 Tonga.
