drm/tegra: Add NVJPG driver

2025-11-14T18:41:55+00:00

Add support for booting and using NVJPG on Tegra210 to the Host1x and TegraDRM drivers. This driver only supports the new TegraDRM uAPI.

drm/tegra: Hide fbdev support behind config option

2023-04-06T10:18:54+00:00

Only build tegra's fbdev emulation if CONFIG_DRM_FBDEV_EMULATION has been enabled. As part of this change, move the code into its own source file. No functional changes. Signed-off-by: Thomas Zimmermann Signed-off-by: Thierry Reding

drm/tegra: Add code for booting RISC-V based engines

2022-11-25T15:14:58+00:00

Add helper code for booting RISC-V based engines where firmware is located in a carveout. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

drm/tegra: Add NVDEC driver

2021-12-16T13:07:06+00:00

Add support for booting and using NVDEC on Tegra210, Tegra186 and Tegra194 to the Host1x and TegraDRM drivers. Booting in secure mode is not currently supported. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

drm/tegra: Add job firewall

2021-08-10T15:04:05+00:00

Add a firewall that validates jobs before submission to ensure they don't do anything they aren't allowed to do, like accessing memory they should not access. The firewall is functionality-wise a copy of the firewall already implemented in gpu/host1x. It is copied here as it makes more sense for it to live on the DRM side, as it is only needed for userspace job submissions, and generally the data it needs to do its job is easier to access here. In the future, the other implementation will be removed. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

drm/tegra: Implement job submission part of new UAPI

2021-08-10T15:04:05+00:00

Implement the job submission IOCTL with a minimum feature set. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

drm/tegra: Implement new UAPI

2021-08-10T15:04:05+00:00

Implement the non-submission parts of the new UAPI, including channel management and memory mapping. The UAPI is under the CONFIG_DRM_TEGRA_STAGING config flag for now. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

drm/tegra: Move drm_dp_link helpers to Tegra DRM

2019-10-23T16:22:10+00:00

During the discussion of patches that enhance the drm_dp_link helpers it was concluded that these helpers aren't very useful to begin with. After all other drivers have been converted not to use these helpers anymore, move these helpers into the last remaining user: Tegra DRM. If at some point these helpers are deemed more widely useful, they can be moved out into the DRM DP helpers again.

drm/tegra: hda: Extract HDA format parsing code

2019-01-16T12:10:20+00:00

This code can be reused for HDMI, so extract it into a reusable function. Signed-off-by: Thierry Reding

drm/tegra: Add Tegra186 display hub support

2017-12-13T13:16:37+00:00

The display architecture has changed in several significant ways with the new Tegra186 SoC. Shared between all display controllers is a set of common resources referred to as the display hub. The hub generates accesses to memory and feeds them into various composition pipelines, each of which being a window that can be assigned to arbitrary heads. Atomic state is subclassed in order to track the global bandwidth requirements and select and adjust the hub clocks appropriately. The plane code is shared to a large degree with earlier SoC generations, except where the programming differs. Signed-off-by: Thierry Reding
