Hi Kalyan, Rob,
This patch broke the display on the PocoF1 phone (sdm845-xiaomi-beryllium.dts) running AOSP. I can boot to UI but the display is frozen soon after that and dmesg is full of following errors:
[drm:dpu_core_perf_crtc_update:397] [dpu error]crtc-65: failed to update bus bw vote [drm:dpu_core_perf_crtc_check:203] [dpu error]exceeds bandwidth: 7649746kb > 6800000kb [drm:dpu_crtc_atomic_check:969] [dpu error]crtc65 failed performance check -7 [drm:dpu_core_perf_crtc_check:203] [dpu error]exceeds bandwidth: 7649746kb > 6800000kb [drm:dpu_crtc_atomic_check:969] [dpu error]crtc65 failed performance check -7 [drm:dpu_core_perf_crtc_check:203] [dpu error]exceeds bandwidth: 7649746kb > 6800000kb [drm:dpu_crtc_atomic_check:969] [dpu error]crtc65 failed performance check -7
Here is the full dmesg https://pastebin.ubuntu.com/p/PcSdNgMnYw/. Georgi pointed out following patch but it didn't help, https://lore.kernel.org/dri-devel/20201027102304.945424-1-dmitry.baryshkov@l... Am I missing any other followup fix?
