That > should be pte_special() an thus fail vm_normal_page. Perhaps we're missing something, as we're not doing any special marking for the device public pfn/entries. pfn_valid return true, pte_special return false and pfn_t_devmap return false on these pages. Same as system pages. That's the reason vm_normal_page returns the page correctly through pfn_to_page helper. Regards, Alex S.

[PATCH 0/3] drm/etnaviv: IOMMU related fixes
by Michael Walle 26 Aug '21

26 Aug '21

This patch series fixes usage of the etnaviv driver with GPUs behind a IOMMU. It was tested on a NXP LS1028A SoC. Together with Lucas' MMU patches [1] there are not more (GPU internal) MMU nor (system) IOMMU faults on the LS1028A.

[v1 0/2] drm/panel: boe-tv101wum-nl6: Support enabling a 3.3V rail
by yangcong 26 Aug '21

26 Aug '21

The auo,b101uan08.3 panel (already supported by this driver) has a 3.3V rail that needs to be turned on. For previous users of this panel this voltage was directly output by pmic. On a new user (the not-yet-upstream sc7180-trogdor-mrbland board) we need to turn the 3.3V rail on. Add support in the driver for this. yangcong (2): drm/panel: boe-tv101wum-nl6: Support enabling a 3.3V rail dt-bindings: drm/panel: boe-tv101wum-nl6: Support enabling a 3.3V rail .../bindings/display/panel/boe,tv101wum-nl6.yaml | 4 ++++ drivers/gpu/drm/panel/panel-boe-tv101wum-nl6.c | 11 +++++++++++ 2 files changed, 15 insertions(+) -- 2.25.1

[PATCH v2] drm/bridge: parade-ps8640: Reorg the macros
by Philip Chen 26 Aug '21

26 Aug '21

Reorg the macros as follows: (1) Group the registers on the same page together. (2) Group the register and its bit operation together while indenting the macros of the bit operation with one space. Also fix a misnomer for the number of mipi data lanes.

[PULL] drm-intel-fixes
by Rodrigo Vivi 26 Aug '21

26 Aug '21

Hi Dave and Daniel, I also had other 2 display patches, but I decided to keep them out for now because CI_DIF_604 returned a bunch of link training errors on TGL when compared to CI_DIF_603 which is based on drm/drm-fixes. Those patches are: d7f213c131ad ("drm/i915/dp: Use max params for panels < eDP 1.4") dab1b47e57e0 ("drm/i915/dp: return proper DPRX link training result") Likely, this second one is the culprit so I will try to keep this out and try to include the first one, but I'm not sure if CI will return results in time, so let's try to not be late and propagate the other 2 good patches below: Here goes drm-intel-fixes-2021-08-26: - Fix syncmap memory leak - Drop redundant display port debug print Thanks, Rodrigo. The following changes since commit e22ce8eb631bdc47a4a4ea7ecf4e4ba499db4f93: Linux 5.14-rc7 (2021-08-22 14:24:56 -0700) are available in the Git repository at: git://anongit.freedesktop.org/drm/drm-intel tags/drm-intel-fixes-2021-08-26 for you to fetch changes up to 71de496cc489b6bae2f51f89da7f28849bf2836e: drm/i915/dp: Drop redundant debug print (2021-08-26 07:31:52 -0400) ---------------------------------------------------------------- - Fix syncmap memory leak - Drop redundant display port debug print ---------------------------------------------------------------- Matthew Brost (1): drm/i915: Fix syncmap memory leak Swati Sharma (1): drm/i915/dp: Drop redundant debug print drivers/gpu/drm/i915/display/intel_dp.c | 9 ++------- drivers/gpu/drm/i915/gt/intel_timeline.c | 9 +++++++++ 2 files changed, 11 insertions(+), 7 deletions(-)
