Subject: [PATCH v5 0/2] Add L1 and L2 error detection for A53 and A57
Date: Thu,  1 Apr 2021 13:06:13 +0200	[thread overview]
Message-ID: <> (raw)


Resending this mainly because Marc Zyngier and Mark Rutland raised
concerns about using implementation defined registers and I forgot to Cc
them with the last version. This version, like v4 already, should fix
these concerns. Looking forward to feedback.


Changes since v4:
- Rebase on v5.12-rc5

Changes since v3:
- Add edac-enabled property to make EDAC support optional

Changes since v2:
- drop usage of virtual dt node (Robh)
- use read_sysreg_s instead of open coded variant (James Morse)
- separate error retrieving from error reporting
- use smp_call_function_single rather than smp_call_function_single_async
- make driver single instance and register all 'cpu' hierarchy up front once

Changes since v1:
- Split dt-binding into separate patch
- Sort local function variables in reverse-xmas tree order
- drop unnecessary comparison and make variable bool
