Subject: [PATCH v3 0/3] Improve hw reserved PAT checking
Date: Thu, 22 Oct 2026 13:09:16 +0100 [thread overview]
Message-ID: <20261022120915.138606-5-matthew.auld@intel.com> (raw)
This came up recently, where there was some confusion around the
!coh_mode checking, for hw reserved PAT index. Series removes that
completely and just uses pat.valid.
v2:
- Update the kernel-doc to reflect the behaviour change in
get_coh_mode().
- With that we should then harden everything else and
make this consistent. Add a new patch for this.
v3:
- Improve is_valid() to return false for out-of-range (Tejas).
