Changes in v2:
- Added commit hash to xtheadvector
- Simplified riscv,isa vector removal fix to not mess with the DT riscv,vendorid
- Moved riscv,vendorid parsing into a different patch and cache the value to be used by alternative patching
- Reduce riscv,vendorid missing severity to "info"
- Separate vendor extension list to vendor files
- xtheadvector no longer puts v in the elf_hwcap
- Only patch vendor extension if all harts are associated with the same vendor. This is the best chance the kernel has for working properly if there are multiple vendors.
I don't agree with this lack of trust in what firmware is telling us.
I'm not really gonna review this v2 until discussion has finished in v1 about some things, I fundamentally disagree with handling the same extension differently for different CPU vendors and I don't wanna fracture that conversation further.
- Split hwprobe vendor keys out into vendor file
- Add attribution for Heiko's patches
- Link to v1: https://lore.kernel.org/r/20240411-dev-charlie-support_thead_vector_6_9-v1-0...
