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@linaro.org/
Am I missing any other followup fix?
Regards,
Amit Pundir
