2024-02-23drm/xe: Use pointers in trace eventsLucas De Marchi1-15/+15
Commit a0df2cc858c3 ("drm/xe/xe_bo_move: Enhance xe_bo_move trace") inadvertently reverted commit 8d038f49c1f3 ("drm/xe: Fix cast on trace variable"), breaking the build on 32bits. As noted by Ville, there's no point in converting the pointers to u64 and add casts everywhere. In fact, it's better to just use %p and let the address be hashed. Convert all the cases in xe_trace.h to use pointers.

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().
