drm/amd/display: use kvmalloc for dc_state (v2)

2019-08-13T03:01:53+00:00

It's large and doesn't need contiguous memory. Fixes allocation failures in some cases. v2: kvfree the memory. Reviewed-by: Andrey Grodzovsky Signed-off-by: Alex Deucher

Pull Wimplicit-fallthrough enablement from Gustavo A. R. Silva: "This marks switch cases where we are expecting to fall through, and globally enables the -Wimplicit-fallthrough option in the main Makefile. Finally, some missing-break fixes that have been tagged for -stable: - drm/amdkfd: Fix missing break in switch statement - drm/amdgpu/gfx10: Fix missing break in switch statement With these changes, we completely get rid of all the fall-through warnings in the kernel" * tag 'Wimplicit-fallthrough-5.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux: Makefile: Globally enable fall-through warning drm/i915: Mark expected switch fall-throughs drm/amd/display: Mark expected switch fall-throughs drm/amdkfd/kfd_mqd_manager_v10: Avoid fall-through warning drm/amdgpu/gfx10: Fix missing break in switch statement drm/amdkfd: Fix missing break in switch statement perf/x86/intel: Mark expected switch fall-throughs mtd: onenand_base: Mark expected switch fall-through afs: fsclient: Mark expected switch fall-throughs afs: yfsclient: Mark expected switch fall-throughs can: mark expected switch fall-throughs firewire: mark expected switch fall-throughs

drm/amd/display: Mark expected switch fall-throughs

2019-07-26T01:13:22+00:00

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R. Silva

drm/amd/display: Set enabled to false at start of audio disable

2019-07-23T20:27:09+00:00

[Why] In an effort to stop redundant calls to dce110_disable_audio_stream the audio->enabled flag was added to the audio resource struct. While this state probably shouldn't have been tracked on the audio struct itself it still works fine for some sequences. However, it does not work for cases where we're freeing the audio resource (such as hotplugs) or when dynamic audio is enabled. In these cases the pipe_ctx->stream_res.audio = NULL before we can set audio->enabled = false. The next time we acquire the audio resource such as on hotplug the audio will not be enabled for the stream since DC thinks it's still enabled. Audio state tracking should cover this sequence. [How] Set audio->enabled = false at the start as long as we have pipe_ctx->stream_res.audio. Signed-off-by: Nicholas Kazlauskas Reviewed-by: Zhan Liu Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: handle active dongle port type is DP++ or DP case

2019-07-18T19:17:20+00:00

[Why]: Some active dongles have DP++ port and DP port at the same time. Current code doesn't cover DP++ case and processes as default DVI case, in which audio is disabled. Because of dual mode, DP case is also treat as DVI case for the other port. [How]: According DP 1.4 spec, add DP++ procedure similar with HDMI case. Also add None dongle type for DP case.

drm/amd/display: do not read link setting if edp not connected

2019-07-18T19:17:20+00:00

[Why] Previously assume eDP sink present if connector present. Do not need to enforce this restriction. Fix issue where driver attempt to read link setting even though no edp connected. {How] Only read link setting after reading connection status.

drm/amd/display: Increase size of audios array

2019-07-18T19:17:20+00:00

[Why] The audios array defined in "struct resource_pool" is only 6 (MAX_PIPES) but the max number of audio devices (num_audio) is 7. In some projects, it will run out of audios array. [How] Incraese the audios array size to 7. Signed-off-by: Tai Man Reviewed-by: Joshua Aberback Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: drop ASSERT() if eDP panel is not connected

2019-07-18T19:17:20+00:00

[Why] For boards that support eDP but do not have a physical eDP display connected an ASSERT will be thrown. This is not a critical failure and shouldn't be treated as such. [How] Drop the assertion.

drm/amd/display: Only enable audio if speaker allocation exists

2019-07-18T19:17:20+00:00

[Why] In dm_helpers_parse_edid_caps, there is a corner case where no speakers can be allocated even though the audio mode count is greater than 0. Enabling audio when no speaker allocations exists can cause issues in the video stream. [How] Add a check to not enable audio unless one or more speaker allocations exist (since doing this can cause issues in the video stream).

drm/amd/display: Fix dc_create failure handling and 666 color depths

2019-07-18T19:17:20+00:00

[Why] It is possible (but very unlikely) that constructing dc fails before current_state is created. We support 666 color depth in some scenarios, but this isn't handled in get_norm_pix_clk. It uses exactly the same pixel clock as the 888 case. [How] Check for non null current_state before destructing. Add case for 666 color depth to get_norm_pix_clk to avoid assertion.
