Subject: [PATCH v2 00/12] drm/i915: More uncore nukage from display code
Date: Tue, 31 Mar 2026 18:42:47 +0300 [thread overview]
Message-ID: <20260331154259.24600-1-ville.syrjala@linux.intel.com> (raw)
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Ggt rid of more intel_uncore stuff from the display code:
- new intel_mchbar_read*() abstraction for MCHBAR registers
- some direct replacement of intel_uncore_{read,write}()
with intel_de_{read,write}()
v2: Fix bisection on xe (nop intel_uncore_read64())
Deal with review comments
Ville Syrjälä (12):
drm/i915/qgv: Use intel_de_read() for MTL_MEM_SS_INFO* reads
drm/i915/mchbar: Provide intel_mchbar_read*() abstraction
drm/i915/mchbar: Define the end of the MCHBAR mirror
drm/i915/mchbar: WARN when accessing non-MCHBAR registers via
intel_mchbar_read*()
drm/i915/mchbar: Use intel_mchbar_read() instead of intel_de_read()
drm/i915/mchbar: Use intel_mchbar_read*() instead of
intel_uncore_read*()
drm/i915/de: Add intel_de_read16()
drm/i915/de: s/intel_de_read64_2x32()/intel_de_read64_2x32_volatile()/
drm/i915/de: Add a simple intel_de_read64_2x32()
drm/i915/vrr: Use intel_de_read64_2x32()
drm/i915/mchbar: Use intel_de_read*() for MCHBAR register accesses
drm/i915/rom: Use intel_de for SPI ROM register access
