drm/tegra: gem: Do not try to dereference ERR_PTR()

2022-06-09T08:29:40+00:00

[ Upstream commit cb7e1abc2c73633e1eefa168ab2dad6e838899c9 ] When mapping the DMA-BUF attachment fails, map->sgt will be an ERR_PTR- encoded error code and the cleanup code would try to free that memory, which obviously would fail. Zero out that pointer after extracting the error code when this happens so that kfree() can do the right thing.

drm-misc-next for v5.18: UAPI Changes: Cross-subsystem Changes: - Improve performance of some fbdev ops, in some cases up to 6x faster. Core Changes: - Some small DP fixes. - Find panels in subnodes of OF devices, and add of_get_drm_panel_display_mode to retrieve mode. - Add drm_object_property_get_default_value and use it for resetting zpos in plane state reset, removing the need for individual drivers to do it. - Same for color encoding and color range props. - Update panic handling todo doc. - Add todo that format conversion helpers should be sped up similarly to fbdev ops. Driver Changes: - Add panel orientation property to simpledrm for quirked panels. - Assorted small fixes to tiny/repaper, nouveau, stm, omap, ssd130x. - Add crc support to stm/ltdc. - Add MIPI DBI compatible SPI driver - Assorted small fixes to tiny panels and bridge drivers. - Add AST2600 support to aspeed.

drm/tegra: Changes for v5.18-rc1 This contains a couple more minor fixes that didn't seem urgent enough for v5.17. On top of that this improves YUV format support on older chips.

drm/tegra: Support semi-planar formats on Tegra114+

2022-03-01T10:13:09+00:00

The NV12, NV21, NV16, NV61, NV24 and NV42 formats are supported by Tegra114 and later display hardware. Add the necessary programming to allow them to be used. Note that this does not work for Tegra186 and later yet because those generations have a different display architecture that doesn't support the same formats. Signed-off-by: Thierry Reding

drm/tegra: Fix planar formats on Tegra186 and later

2022-03-01T10:13:09+00:00

Use the correct pitch when programming the DC_WIN_PLANAR_STORAGE_UV register's PITCH_U field to ensure the correct value is used in all cases. This isn't currently causing any problems because the pitch for both U and V planes is always the same. Signed-off-by: Thierry Reding
