drm/i915: Fix wrong escape clock divisor init for GLK

2019-08-16T08:12:51+00:00

commit 73a0ff0b30af79bf0303d557eb82f1d1945bb6ee upstream. According to Bspec clock divisor registers in GeminiLake should be initialized by shifting 1(<<) to amount of correspondent divisor. While i915 was writing all this time that value as is. Surprisingly that it by accident worked, until we met some issues with Microtech Etab. v2: Added Fixes tag and cc v3: Added stable to cc as well.

[ Upstream commit 6ac25e6d5b2fbf251e9fa2f4131d42c815b43867 ] [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

[ Upstream commit 0905f32977268149f06e3ce6ea4bd6d374dd891f ] [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.

drm/amd/display: use encoder's engine id to find matched free audio device

2019-08-16T08:12:44+00:00

[ Upstream commit 74eda776d7a4e69ec7aa1ce30a87636f14220fbb ] [Why] On some platforms, the encoder id 3 is not populated. So the encoders are not stored in right order as index (id: 0, 1, 2, 4, 5) at pool. This would cause encoders id 4 & id 5 to fail when finding corresponding audio device, defaulting to the first available audio device. As result, we cannot stream audio into two DP ports with encoders id 4 & id 5. [How] It need to create enough audio device objects (0 - 5) to perform matching. Then use encoder engine id to find matched audio device. Signed-off-by: Tai Man Reviewed-by: Charlene Liu Acked-by: Leo Li Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/i915/gvt: fix incorrect cache entry for guest page mapping

commit 7366aeb77cd840f3edea02c65065d40affaa7f45 upstream. GPU hang observed during the guest OCL conformance test which is caused by THP GTT feature used durning the test. It was observed the same GFN with different size (4K and 2M) requested from the guest in GVT. So during the guest page dma map stage, it is required to unmap first with orginal size and then remap again with requested size.

drm/nouveau: fix memory leak in nouveau_conn_reset()

[ Upstream commit 09b90e2fe35faeace2488234e2a7728f2ea8ba26 ] In nouveau_conn_reset(), if connector->state is true, __drm_atomic_helper_connector_destroy_state() will be called, but the memory pointed by asyc isn't freed. Memory leak happens in the following function __drm_atomic_helper_connector_reset(), where newly allocated asyc->state will be assigned to connector->state. So using nouveau_conn_atomic_destroy_state() instead of __drm_atomic_helper_connector_destroy_state to free the "old" asyc.

drm/msm: Depopulate platform on probe failure

2019-07-31T05:27:01+00:00

[ Upstream commit 4368a1539c6b41ac3cddc06f5a5117952998804c ] add_display_components() calls of_platform_populate, and we depopluate on pdev remove, but not when probe fails. So if we get a probe deferral in one of the components, we won't depopulate the platform. This causes the core to keep references to devices which should be destroyed, which causes issues when those same devices try to re-initialize on the next probe attempt. I think this is the reason we had issues with the gmu's device-managed resources on deferral (worked around in commit 94e3a17f33a5).
