Re: [PATCH 0/2] Add EDAC support for Kryo CPU core caches

Hi Sai,

This series implements EDAC support for error reporting on
Kryo{3,4}XX CPU caches L1,L2, L3-SCU. All the cores(big.LITTLE)
in Kryo{3,4}XX CPUs implement RAS extensions and use interrupt
based ECC mechanism to report errors.

This series has been tested on SC7180, SDM845, SM8150 SoCs with
Kryo{3,4}XX CPU cores based on ARM Cortex-A55, Cortex-A75 and
Cortex-A76.

This implementation is platform specific in contrast to the
patch posted last time for generic error reporting on arm cortex
implementations with RAS extensions by Kyle Yan.

I think that series was dropped because it was too soc-specific and overlaps with the v8.2
kernel first support. That series was superseded by:
lore.kernel.org/r/1562086280-5351-1-git-send-email-baicar@os.amperecomputing.com

Can you work with Tyler on a combined series? The combined support may need to look quite
different. (DT and big/little being the obvious differences).

I'm afraid this is the tip of the kernel-first-RAS iceberg.


Thanks,

James
