drm/amd/display: add connector type check for CRC source set

2021-12-17T09:12:24+00:00

[ Upstream commit 2da34b7bb59e1caa9a336e0e20a76b8b6a4abea2 ] [Why] IGT bypass test will set crc source as DPRX,and display DM didn`t check connection type, it run the test on the HDMI connector ,then the kernel will be crashed because aux->transfer is set null for HDMI connection. This patch will skip the invalid connection test and fix kernel crash issue. [How] Check the connector type while setting the pipe crc source as DPRX or auto,if the type is not DP or eDP, the crtc crc source will not be set and report error code to IGT test,IGT will show the this subtest as no valid crtc/connector combinations found. 116.779714] [IGT] amd_bypass: starting subtest 8bpc-bypass-mode [ 117.730996] BUG: kernel NULL pointer dereference, address: 0000000000000000 [ 117.731001] #PF: supervisor instruction fetch in kernel mode [ 117.731003] #PF: error_code(0x0010) - not-present page [ 117.731004] PGD 0 P4D 0 [ 117.731006] Oops: 0010 [#1] SMP NOPTI [ 117.731009] CPU: 11 PID: 2428 Comm: amd_bypass Tainted: G OE 5.11.0-34-generic #36~20.04.1-Ubuntu [ 117.731011] Hardware name: AMD CZN/, BIOS AB.FD 09/07/2021 [ 117.731012] RIP: 0010:0x0 [ 117.731015] Code: Unable to access opcode bytes at RIP 0xffffffffffffffd6.

drm/amd/display: Fix for the no Audio bug with Tiled Displays

[ Upstream commit 5ceaebcda9061c04f439c93961f0819878365c0f ] [WHY] It seems like after a series of plug/unplugs we end up in a situation where tiled display doesnt support Audio. [HOW] The issue seems to be related to when we check streams changed after an HPD, we should be checking the audio_struct as well to see if any of its values changed.

drm/amdgpu: fix set scaling mode Full/Full aspect/Center not works on vga and dvi connectors

2021-11-26T09:47:22+00:00

commit bf552083916a7f8800477b5986940d1c9a31b953 upstream. amdgpu_connector_vga_get_modes missed function amdgpu_get_native_mode which assign amdgpu_encoder->native_mode with *preferred_mode result in amdgpu_encoder->native_mode.clock always be 0. That will cause amdgpu_connector_set_property returned early on: if ((rmx_type != DRM_MODE_SCALE_NONE) && (amdgpu_encoder->native_mode.clock == 0)) when we try to set scaling mode Full/Full aspect/Center. Add the missing function to amdgpu_connector_vga_get_mode can fix this. It also works on dvi connectors because amdgpu_connector_dvi_helper_funcs.get_mode use the same method.
