[PATCH v2 0/9] IFS support for GNR and SRF

From: Jithu Joseph
Date: Fri Sep 22 2023 - 19:30:20 EST


Changes in v2
Ilpo Jarvinen
- Use GENMASK_ULL() / FIELD_GET() for bitops (patch 01)
- Avoid mixing u8 type and bitfields in certain MSR structure
scenarios (patch03 also suggested by Dave Hansen)
- Expand bitfield structures to use consistent genx naming (patch 04)
- Replace goto with do / while (patch 03)
- general formatting (multiple patches)
- remove un-necessary parenthesis
- reformat commit message to use whole allowed 72 columns
- alignment changes
Other change
- fold v1 04/10 and 05/10 into v2 patch 04/09 to satisfy build
constraints due to consistent genx naming
v1 submission:

This series adds In Field Scan(IFS) support for newer CPUs like Granite
Rapids(GNR) and Sierra Forest(SRF).

There are changes in the IFS image loading and test flow to support
these new CPUs.

Note to reviewers:
- patch 01/09 adds a bit mask to arch/x86/.../msr-index.h,
hence x86 maintainers are cc-d.
- patch 04/09 modifies an existing tracepoint, cc Steven Rostedt
- Rest are localized to IFS driver
