2020-04-14drm/bridge: anx6345: set correct BPC for display_info of connectorVasily Khoruzhick1-0/+3
Some drivers (e.g. sun4i-drm) need this info to decide whether they need to enable dithering. Currently driver reports what panel supports and if panel supports 8 we don't get dithering enabled. Hardcode BPC to 6 for now since that's the only BPC that driver supports.

2020-04-14drm/i915: do AUD_FREQ_CNTRL state save on all gen9+ platformsKai Vehmanen1-2/+2
Replace the TGL/ICL specific platform checks with a more generic check using INTEL_GEN(). Fixes bug with broken audio after S3 resume on JSL platforms. An initial version of state save and restore of AUD_FREQ_CNTRL register was added for subset of platforms in commit 87c1694533c9 ("drm/i915: save AUD_FREQ_CNTRL state at audio domain suspend"). The state save has proven to work well and it is needed in newer platforms, so needs to be extended. Although the logic is not in practise needed on GEN9/10 systems, follow the hardware specification and apply state and restore on all gen9+ platforms.

2020-04-13drm/i915/perf: Do not clear pollin for small user read buffersAshutosh Dixit1-54/+11
It is wrong to block the user thread in the next poll when OA data is already available which could not fit in the user buffer provided in the previous read. In several cases the exact user buffer size is not known. Blocking user space in poll can lead to data loss when the buffer size used is smaller than the available data. This change fixes this issue and allows user space to read all OA data even when using a buffer size smaller than the available data using multiple non-blocking reads rather than staying blocked in poll till the next timer interrupt. v2: Fix ret value for blocking reads (Umesh) v3: Mistake during patch send (Ashutosh) v4: Remove -EAGAIN from comment (Umesh) v5: Improve condition for clearing pollin and return (Lionel) v6: Improve blocking read loop and other cleanups (Lionel) v7: Added Cc stable Testcase: igt/perf/polling-small-buf Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Signed-off-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Cc: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Cc: <stable@vger.kernel.org> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20200403010120.3067-1-ashutosh.dixit@intel.com (cherry-picked from commit 6352219c39c04ed3f9a8d1cf93f87c21753a213e) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2020-04-13device_cgroup: Cleanup cgroup eBPF device filter codeOdin Ugedal1-1/+1
Original cgroup v2 eBPF code for filtering device access made it possible to compile with CONFIG_CGROUP_DEVICE=n and still use the eBPF filtering. Change commit 4b7d4d453fc4 ("device_cgroup: Export devcgroup_check_permission") reverted this, making it required to set it to y. Since the device filtering (and all the docs) for cgroup v2 is no longer a "device controller" like it was in v1, someone might compile their kernel with CONFIG_CGROUP_DEVICE=n. Then (for linux 5.5+) the eBPF filter will not be invoked, and all processes will be allowed access to all devices, no matter what the eBPF filter says.

2020-04-13soc / drm: mediatek: Fix mediatek-drm device probingEnric Balletbo i Serra1-12/+19
In the actual implementation the same compatible string "mediatek,<chip>-mmsys" is used to bind the clock drivers (drivers/soc/mediatek) as well as to the gpu driver (drivers/gpu/drm/mediatek/mtk_drm_drv.c). This ends with the problem that the only probed driver is the clock driver and there is no display at all. In any case having the same compatible string for two drivers is not correct and should be fixed. To fix this, and maintain backward compatibility, we can consider that the mmsys driver is the top-level entry point for the multimedia subsystem, so is not a pure clock controller but a system controller, and the drm driver is instantiated by that MMSYS driver.

With timeslice yielding on a semaphore, we may complete timeslices much faster than we were expecting and already have yielded the stuck request. Before complaining that timeslicing is not enabled, check that we haven't already applied the switch.

2020-04-09drm/dp_mst: Print errors on ACT timeoutsLyude Paul1-2/+6
Although it's not unexpected for drm_dp_check_act_status() to fail due to DPCD read failures (as the hub may have just been unplugged suddenly), timeouts are a bit more worrying as they either mean we need a longer timeout value, or we aren't setting up payload allocations properly. So, let's start printing errors on timeouts.

2020-04-09drm/dp_mst: Increase ACT retry timeout to 3sLyude Paul1-22/+33
Currently we only poll for an ACT up to 30 times, with a busy-wait delay of 100µs between each attempt - giving us a timeout of 2900µs. While this might seem sensible, it would appear that in certain scenarios it can take dramatically longer then that for us to receive an ACT. On one of the EVGA MST hubs that I have available, I observed said hub sometimes taking longer then a second before signalling the ACT. These delays mostly seem to occur when previous sideband messages we've sent are NAKd by the hub, however it wouldn't be particularly surprising if it's possible to reproduce times like this simply by introducing branch devices with large LCTs since payload allocations have to take effect on every downstream device up to the payload's target. So, instead of just retrying 30 times we poll for the ACT for up to 3ms, and additionally use usleep_range() to avoid a very long and rude busy-wait. Note that the previous retry count of 30 appears to have been arbitrarily chosen, as I can't find any mention of a recommended timeout or retry count for ACTs in the DisplayPort 2.0 specification. This also goes for the range we were previously using for udelay(), although I suspect that was just copied from the recommended delay for link training on SST devices.
