Subject: [PATCH v5 0/4] Add DPA->HPA translation to dram & general_media events
Date: Mon, 29 Apr 2024 17:34:20 -0700 [thread overview]
Message-ID: <cover.1714435815.git.alison.schofield@intel.com> (raw)
From: Alison Schofield <alison.schofield@intel.com>
Changes in v5:
- Add Shiyang Ruan's DPA mask fixup patch[1] (Dan)
The DPA flags fixup is a required precursor patch to this set so I
updated Ruan's patch based on the last review messages and added it
here. That patch can be merged ahead of this set.
- Link to v4: https://lore.kernel.org/cover.1714102202.git.alison.schofield@intel.com/

Begin Cover Letter:
Add HPA translations to CXL events: cxl_dram and cxl_general_media
Patch 1:
The DPA mask fix up patch must precede or be part of this set.
It fixes the issue where upper 32 bits of DPA are truncated.
Patches 2 & 3:
Before adding the new support, do some housekeeping and move related
helpers to the region driver because there is no looking up region
related info without CONFIG_CXL_REGION.
Patch 4:
The new functionality is introduced - cxl_dram & cxl_general_media
events. Lookup and log the DPA->HPA translation along with the
region name and region uuid.
Alison Schofield (4):
cxl/trace: Correct DPA field masks for general_media & dram events
cxl/region: Move cxl_dpa_to_region() work to the region driver
cxl/region: Move cxl_trace_hpa() work to the region driver
cxl/core: Add region info to cxl_general_media and cxl_dram events
