commit 9e61ef8d219877202d4ee51d0d2ad9072c99a262 upstream. In order for display colorimetry to work correctly on DP displays we need to send the VSC SDP packet. We should only do so for panels with DPCD revision greater or equal to 1.4 as older receivers might have problems with it.

2024-04-10kbuild: make -Woverride-init warnings more consistentArnd Bergmann5-5/+5
[ Upstream commit c40845e3195d074b34f8f8e400e28c9403a06588 ] The -Woverride-init warn about code that may be intentional or not, but the inintentional ones tend to be real bugs, so there is a bit of disagreement on whether this warning option should be enabled by default and we have multiple settings in scripts/Makefile.extrawarn as well as individual subsystems. Older versions of clang only supported -Wno-initializer-overrides with the same meaning as gcc's -Woverride-init, though all supported versions now work with both. Because of this difference, an earlier cleanup of mine accidentally turned the clang warning off for W=1 builds and only left it on for W=2, while it's still enabled for gcc with W=1. There is also one driver that only turns the warning off for newer versions of gcc but not other compilers, and some but not all the Makefiles still use a cc-disable-warning conditional that is no longer needed with supported compilers here. Address all of the above by removing the special cases for clang and always turning the warning off unconditionally where it got in the way, using the syntax that is supported by both compilers.

commit 2f14c0c8cae8e9e3b603a3f91909baba66540027 upstream. The monitor shipped with the Framework 16 supports VRR [1], but it's not being advertised. This is because the detailed timing block doesn't contain `EDID_DETAIL_MONITOR_RANGE` which amdgpu looks for to find min and max frequencies.

pipe with no plane [ Upstream commit 86e9523fb0efce27095d3086473c739cce720d01 ] [WHY] When committing an update with ODM combine change when the plane is removing or already removed, we fail to detect odm change in pipe update flags. This has caused mismatch between new dc state and the actual hardware state, because we missed odm programming. [HOW] - Detect odm change even for otg master pipe without a plane. - Update odm config before calling program pipes for pipe with planes. The commit also updates blank pattern programming when odm is changed without plane. This is because number of OPP is changed when ODM combine is changed. Blank pattern is per OPP so we will need to reprogram OPP based on the new pipe topology.

2024-02-22drm/amd/display: Fix potential null pointer dereference in dc_dmub_srvSrinivasan Shanmugam1-2/+5
Fixes potential null pointer dereference warnings in the dc_dmub_srv_cmd_list_queue_execute() and dc_dmub_srv_is_hw_pwr_up() functions. In both functions, the 'dc_dmub_srv' variable was being dereferenced before it was checked for null. This could lead to a null pointer dereference if 'dc_dmub_srv' is null. The fix is to check if 'dc_dmub_srv' is null before dereferencing it. Thus moving the null checks for 'dc_dmub_srv' to the beginning of the functions to ensure that 'dc_dmub_srv' is not null when it is dereferenced. Found by smatch & thus fixing the below: drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:133 dc_dmub_srv_cmd_list_queue_execute() warn: variable dereferenced before check 'dc_dmub_srv' (see line 128) drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:1167 dc_dmub_srv_is_hw_pwr_up() warn: variable dereferenced before check 'dc_dmub_srv' (see line 1164) Fixes: 028bac583449 ("drm/amd/display: decouple dmcub execution to reduce lock granularity") Fixes: 65138eb72e1f ("drm/amd/display: Add DCN35 DMUB") Cc: JinZe.Xu <jinze.xu@amd.com> Cc: Hersen Wu <hersenxs.wu@amd.com> Cc: Josip Pavic <josip.pavic@amd.com> Cc: Roman Li <roman.li@amd.com> Cc: Qingqing Zhuo <Qingqing.Zhuo@amd.com> Cc: Harry Wentland <Harry.Wentland@amd.com> Cc: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Cc: Aurabindo Pillai <aurabindo.pillai@amd.com> Cc: Tom Chung <chiahsuan.chung@amd.com> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Reviewed-by: Tom Chung <chiahsuan.chung@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

[Why] Observe error message "Can't retrieve aconnector in hpd_rx_irq_offload_work" when boot up with a mst tbt4 dock connected. After analyzing, there are few parts needed to be adjusted: 1. hpd_rx_offload_wq[].aconnector is not initialzed before the dmub outbox hpd_irq handler get registered which causes the error message. 2. registeration of hpd and hpd_rx_irq event for usb4 dp tunneling is not aligned with legacy interface sequence [How] Put DMUB_NOTIFICATION_HPD and DMUB_NOTIFICATION_HPD_IRQ handler registration into register_hpd_handlers() to align other interfaces and get hpd_rx_offload_wq[].aconnector initialized earlier than that. Leave DMUB_NOTIFICATION_AUX_REPLY registered as it was since we need that while calling dc_link_detect().

2024-02-15drm/amdgpu/display: Initialize gamma correction mode variable in ↵Srinivasan Shanmugam1-4/+1
dcn30_get_gamcor_current() The dcn30_get_gamcor_current() function is responsible for determining the current gamma correction mode used by the display controller. However, the 'mode' variable, which stores the gamma correction mode, was not initialized before its first usage, leading to an uninitialized symbol error. Thus initializes the 'mode' variable with a default value of LUT_BYPASS before the conditional statements in the function, improves code clarity and stability, ensuring correct behavior of the dcn30_get_gamcor_current() function in determining the gamma correction mode. Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_dpp_cm.c:77 dpp30_get_gamcor_current() error: uninitialized symbol 'mode'.
