drm/tegra: Changes for v5.19-rc1 Only a few fixes this time, and some debuggability improvements. Signed-off-by: Dave Airlie From: Thierry Reding Link: https://patchwork.freedesktop.org/patch/msgid/20220506164004.3922226-1-thierry.reding@gmail.com

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

2022-05-06T13:52:49Z

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/display: Move SCDC helpers into display-helper library

2022-04-25T09:19:37Z

SCDC is the Status and Control Data Channel for HDMI. Move the SCDC helpers into display/ and split the header into files for core and helpers. Update all affected drivers. No functional changes. To avoid the proliferation of Kconfig options, SCDC is part of DRM's support for HDMI. If necessary, a new option could make SCDC an independent feature.

drm/display: Introduce a DRM display-helper module

2022-04-25T09:19:21Z

Replace the DP-helper module with a display-helper module. The support for DisplayPort becomes an internal option that drivers have to select. Update all related Kconfig and Makefile rules. Besides the existing code for DisplayPort, the new module will contain helpers for other video-output standards, such as HDMI. Drivers will have to select their required video-output helpers. Linking all display-related code into a single module avoids the proliferation of small kernel modules. The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz, and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespace to drm_display_helper. v2: * mention module parameters in commit message (Javier) * distiguish between display module and DP support in Kconfig * update Makefile rules for DP helpers * move Kconfig rules into separate file under display/ Signed-off-by: Thomas Zimmermann Reviewed-by: Lyude Paul Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-4-tzimmermann@suse.de

drm: Rename dp/ to display/

2022-04-25T09:17:45Z

Rename dp/ to display/ to account for additional display-related helpers, such as HDMI. Update all related include statements. No functional changes. Various drivers, such as i915 and amdgpu, use similar naming scheme by putting code for video-output standards into a local display/ directory. The new directory's name is aligned with this convention. v2: * update commit message (Javier) Signed-off-by: Thomas Zimmermann Reviewed-by: Lyude Paul Reviewed-by: Javier Martinez Canillas Reviewed-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-3-tzimmermann@suse.de

drm/tegra: vic: Fix unused-function warnings

The use of the old-style SET_RUNTIME_PM_OPS() and SET_SYSTEM_SLEEP_PM_OPS() macros requires function definitions to be hidden to avoid drivers/gpu/drm/tegra/vic.c:326:12: error: 'vic_runtime_suspend' defined but not used [-Werror=unused-function] 326 | static int vic_runtime_suspend(struct device *dev) | ^~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/tegra/vic.c:292:12: error: 'vic_runtime_resume' defined but not used [-Werror=unused-function] 292 | static int vic_runtime_resume(struct device *dev) | ^~~~~~~~~~~~~~~~~~ Use the new-style SYSTEM_SLEEP_PM_OPS() and RUNTIME_PM_OPS() instead.

2022-03-04T03:41:57Z

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: Support semi-planar formats on Tegra114+

2022-03-01T10:13:09Z

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
