[PATCH 1/2] drm/i915/backlight: Drop duplicate intel_panel_actually_set_backlight()
by Hans de Goede 16 Dec '21

16 Dec '21

After the recent refactoring of the backlight code the contents of intel_panel_actually_set_backlight() is exactly the same (minus a small wording difference in the drm_dbg_kms() as the contents if the more widely used intel_backlight_set_pwm_level() function. Drop the duplicate intel_panel_actually_set_backlight() function.

[PATCH v3 0/8] DG2 accelerated migration/clearing support
by Matthew Auld 16 Dec '21

16 Dec '21

Enable accelerated moves and clearing on DG2. On such HW we have minimum page size restrictions when accessing LMEM from the GTT, where we now have to use 64K GTT pages or larger. With the ppGTT the page-table also has a slightly different layout from past generations when using the 64K GTT mode(which is still enabled on via some PDE bit), where it is now compacted down to 32 qword entries. Note that on discrete the paging structures must also be placed in LMEM, and we need to able to modify them via the GTT itself(see patch 7), which is one of the complications here. The series needs to be applied on top of the DG2 enabling branch: https://cgit.freedesktop.org/~ramaling/linux/log/?h=dg2_enabling_ww49.3 Matthew Auld (8): drm/i915/migrate: don't check the scratch page drm/i915/migrate: fix offset calculation drm/i915/migrate: fix length calculation drm/i915/selftests: handle object rounding drm/i915/gtt: allow overriding the pt alignment drm/i915/gtt: add xehpsdv_ppgtt_insert_entry drm/i915/migrate: add acceleration support for DG2 drm/i915/migrate: turn on acceleration for DG2 drivers/gpu/drm/i915/gt/gen8_ppgtt.c | 50 +++++- drivers/gpu/drm/i915/gt/intel_gtt.h | 10 +- drivers/gpu/drm/i915/gt/intel_migrate.c | 195 ++++++++++++++++----- drivers/gpu/drm/i915/gt/intel_ppgtt.c | 16 +- drivers/gpu/drm/i915/gt/selftest_migrate.c | 1 + 5 files changed, 221 insertions(+), 51 deletions(-) -- 2.31.1

[PULL] drm-misc-next
by Thomas Zimmermann 16 Dec '21

16 Dec '21

Hi Dave and Daniel, here's this week's PR for drm-misc-next for what will become Linux 5.17. Every single patchset in this PR is awesome: vmwgfx now supports GL 4.3 userspace and GEM (yeah!), simpledrm added support for Apple M1 firmware framebuffers, the SPRD drivers finally got merged, vc4 added support for 10-bit YUV output. And of course, we have the usual round of bug fixes. Besides the DRM updates, there's a backmerge from drm-next that brings drm-misc-next up to v5.16-rc5.
