Subject: [PATCH v3 0/2] io-pgtable-arm + drm/msm: Extend iova fault debugging
Date: Wed, 22 May 2024 14:50:03 -0700	[thread overview]
Message-ID: <20240522215014.26007-1-robdclark@gmail.com> (raw)

From: Rob Clark <robdclark@chromium.org>

This series extends io-pgtable-arm with a method to retrieve the page
table entries traversed in the process of address translation, and then
beefs up drm/msm gpu devcore dump to include this (and additional info)
in the devcore dump.

This is a respin of https://patchwork.freedesktop.org/series/94968/
(minus a patch that was already merged)

v2: Fix an armv7/32b build error in the last patch
v3: Incorperate Will Deacon's suggestion to make the interface
    callback based.

Rob Clark (2):
  iommu/io-pgtable-arm: Add way to debug pgtable walk
  drm/msm: Extend gpu devcore dumps with pgtbl info
