drm/tegra: Implement stream ID related callbacks on engines

2022-07-08T14:27:52+00:00

Implement the get_streamid_offset and can_use_memory_ctx callbacks required for supporting context isolation. Since old firmware on VIC cannot support context isolation without hacks that we don't want to implement, check the firmware binary to see if context isolation should be enabled.

drm/tegra: Support context isolation

2022-07-08T14:27:52+00:00

For engines that support context isolation, allocate a context when opening a channel, and set up stream ID offset and context fields when submitting a job. As of this commit, the stream ID offset and fallback stream ID are not used when context isolation is disabled. However, with upcoming patches that enable a full featured job opcode sequence, these will be necessary. 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: 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: Allocate per-engine channel in core code

2021-08-10T12:49:03+00:00

To avoid code duplication, allocate the per-engine shared channel in the core code instead. This is the usual channel that all jobs are submitted to when MLOCKing is not in use. Once MLOCKs are implemented on Host1x side, we can also update this to avoid allocating a shared channel when MLOCKs are enabled. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

drm/tegra: Correct DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT

2021-05-31T12:29:44+00:00

The format modifier is 64bit, while DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT uses BIT() macro that is 32bit on ARM32. The (modifier &= ~DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT) doesn't work as expected on ARM32 and tegra_fb_get_tiling() fails for the tiled formats on 32bit Tegra because modifier mask isn't applied properly. Use the BIT_ULL() macro to fix this trouble. Fixes: 7b6f846785f4 ("drm/tegra: Support sector layout on Tegra194") Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: Support sector layout on Tegra194

2021-03-31T15:42:14+00:00

Tegra194 has a special physical address bit that enables some memory swizzling logic to support different sector layouts. Support the bit that selects the sector layout which is passed in the framebuffer modifier. Signed-off-by: Thierry Reding

drm/tegra: Count number of display controllers at runtime

2021-03-31T15:42:14+00:00

In order to be able to attach planes to all possible display controllers the exact number of CRTCs must be known. Keep track of the number of the display controllers that register during initialization. Signed-off-by: Thierry Reding

drm/tegra: dc: Parameterize maximum resolution

2021-03-31T15:42:14+00:00

Tegra186 and later support a higher maximum resolution than earlier chips, so make sure to reflect that in the mode configuration. Signed-off-by: Thierry Reding

drm/tegra: output: Support DRM bridges

2020-09-17T10:30:11+00:00

Newer Tegra device-trees will specify a video output graph which involves a bridge. This patch adds initial support for the DRM bridges to the Tegra DRM output. Acked-by: Sam Ravnborg Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding
