2022-05-10drm/amd/display: do not calculate DP2.0 SST payload when link is offWenjing Liu
[Why & How] There is a chance where the RX issues HPD deassert in the middle of link training, this will cause our logic to abort link training and turn off link. However our payload allocation logic needs to use current link settings to determine average time slot per MTP. This will need to use current link bandwidth as divider. This causes divide by zero error occasionally. The fix is to skip DP2.0 payload allocation logic if current link is not in 128b/132b mode.

2022-05-07drm/msm: Fix shutdownDouglas Anderson
When rebooting on my sc7280-herobrine based device, I got a crash. Upon debugging, I found that I was in msm_drv_shutdown() and my "pdev" was the one associated with mdss_probe(). From source, I found that mdss_probe() has the line: platform_set_drvdata(pdev, mdss); ...where "mdss" is of type "struct msm_mdss *". Also from source, I saw that in msm_drv_shutdown() we have the line: struct msm_drm_private *priv = platform_get_drvdata(pdev); This is a mismatch and is the root of the problem. Further digging made it apparent that msm_drv_shutdown() is only supposed to be used for parts of the msm display framework that also call msm_drv_probe() but mdss_probe() doesn't call msm_drv_probe(). Let's remove the shutdown functon from msm_mdss.c. Digging a little further, code inspection found that two drivers that use msm_drv_probe() weren't calling msm_drv_shutdown(). Let's add it to them.

drm uninit If edp modeset init is failed due to panel being not ready and probe defers during drm bind, avoid clearing irqs and dereference hw_intr when hw_intr is null. BUG: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 Call trace: dpu_core_irq_uninstall+0x50/0xb0 dpu_irq_uninstall+0x18/0x24 msm_drm_uninit+0xd8/0x16c msm_drm_bind+0x580/0x5fc try_to_bring_up_master+0x168/0x1c0 __component_add+0xb4/0x178 component_add+0x1c/0x28 dp_display_probe+0x38c/0x400 platform_probe+0xb0/0xd0 really_probe+0xcc/0x2c8 __driver_probe_device+0xbc/0xe8 driver_probe_device+0x48/0xf0 __device_attach_driver+0xa0/0xc8 bus_for_each_drv+0x8c/0xd8 __device_attach+0xc4/0x150 device_initial_probe+0x1c/0x28 Changes in V2: - Update commit message and coreect fixes tag.

2022-05-07drm/msm/dpu: don't access mode pointer before it is setDmitry Baryshkov
Move the initializer for the mode variable to the declaration point to remove unitialized variable access from the DEBUG_DPU macro. This fixes the following warning: drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c:250:37: note: initialize the variable 'mode' to silence this warning Fixes: d7d0e73f7de3 ("drm/msm/dpu: introduce the dpu_encoder_phys_* for writeback") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Patchwork: https://patchwork.freedesktop.org/patch/484346/ Link: https://lore.kernel.org/r/20220502082420.48409-1-dmitry.baryshkov@linaro.org Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
