SDHCI ADMA Error

[kwizart]

I have experienced another ADMA error using 5.5.1-i9000+ kernel

Alright, the clock changes have been submitted (and accepted) upstream. I've yet to been able to reproduce the issue with the clock patch, despite some pretty disk intensive workloads where it used to appear all of the time. I'll leave this open for now, until we can confirm that it is/isn't happening to more than just @kwizart

[xc-racer99]

I've yet to see this issue reappear since the clock changes, so I'm going to call it fixed.

[kwizart]

I may retry with newer 5.9+ kernel at some point.

As a side note, I still monitor:
https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=s3c-multiplatform
and
https://patchwork.ozlabs.org/project/linux-tegra/list/?series=197929 (IIRC, that the same BCM4329 chip).

Is it possible to have a rebase on top on 5.9 kernel ? (with and without powervr)
Thanks in advances.

I'll try to get that done later this week, I want to submit the DTS changes for the audio driver before working on rebasing everything.

@kwizart I've now pushed https://github.com/xc-racer99/linux/tree/v5.9-rc2-all-devices - this has everything except the max17040 rcomp settings and the power domains. The vast majority of these patches are related to PVR. The ones that are due to land in v5.10 are the audio DTS, the FIMC patches (not the sensor drivers, haven't submitted those), and the charger-manager patches.

Edit: Of the 146 patches, 19 are due to land in v5.10, 3 are camera related, 6 are onenand related, 5 are drm related (fimc, tvout, and g2d), 11 are modem related, 87 are PowerVR, and the rest are a mixture of various driver fixups and DTS changes.
