Subject: [PATCH 0/2] platform/x86: ISST: Fix for write lock and suspend/resume
Date: Mon, 29 Dec 2025 10:34:48 -0800 [thread overview]
Message-ID: <20251229183450.823244-1-srinivas.pandruvada@linux.intel.com> (raw)
There are two issues, which are not urgent as the current deployed systems
don't support them, but need fixes:
- Write lock- Even if the TPMI is write locked it will still write to MMIO
- store-restore data during suspend/resume: Not storing and restoring data to
all power domains.

platform/x86: ISST: Add missing write block check
platform/x86: ISST: Store and restore all domains data
