[PATCH AUTOSEL 4.19 024/141] drm/nouveau/kms/gf119-gp10x: push HeadSetControlOutputResource() mthd when encoders change
by Sasha Levin 01 Jun '19

01 Jun '19

From: Ben Skeggs <bskeggs(a)redhat.com> [ Upstream commit a0b694d0af21c9993d1a39a75fd814bd48bf7eb4 ] HW has error checks in place which check that pixel depth is explicitly provided on DP, while HDMI has a "default" setting that we use. In multi-display configurations with identical modelines, but different protocols (HDMI + DP, in this case), it was possible for the DP head to get swapped to the head which previously drove the HDMI output, without updating HeadSetControlOutputResource(), triggering the error check and hanging the core update.

[PATCH AUTOSEL 4.19 021/141] drm/nouveau/disp/dp: respect sink limits when selecting failsafe link configuration

From: Ben Skeggs <bskeggs(a)redhat.com> [ Upstream commit 13d03e9daf70dab032c03dc172e75bb98ad899c4 ] Where possible, we want the failsafe link configuration (one which won't hang the OR during modeset because of not enough bandwidth for the mode) to also be supported by the sink.

[PATCH AUTOSEL 5.0 030/173] drm/bridge: adv7511: Fix low refresh rate selection
by Sasha Levin 01 Jun '19

01 Jun '19

From: Matt Redfearn <matt.redfearn(a)thinci.com> [ Upstream commit 67793bd3b3948dc8c8384b6430e036a30a0ecb43 ] The driver currently sets register 0xfb (Low Refresh Rate) based on the value of mode->vrefresh. Firstly, this field is specified to be in Hz, but the magic numbers used by the code are Hz * 1000. This essentially leads to the low refresh rate always being set to 0x01, since the vrefresh value will always be less than 24000. Fix the magic numbers to be in Hz. Secondly, according to the comment in drm_modes.h, the field is not supposed to be used in a functional way anyway. Instead, use the helper function drm_mode_vrefresh().
