drm/tegra: Run DRM default client setup

2024-09-26T07:31:29Z

Rework fbdev probing to support fbdev_probe in struct drm_driver and remove the old fb_probe callback. Provide an initializer macro for struct drm_driver that sets the callback according to the kernel configuration. Call drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client. The tegra driver specifies a preferred color mode of 32. As this is the default if no format has been given, leave it out entirely. v5: - select DRM_CLIENT_SELECTION Signed-off-by: Thomas Zimmermann Cc: Thierry Reding Cc: Mikko Perttunen Cc: Jonathan Hunter Acked-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-79-tzimmermann@suse.de

drm/tegra: convert to struct drm_edid

drm/tegra: Implement fbdev emulation as in-kernel client

2023-04-06T10:18:56Z

Move code from ad-hoc fbdev callbacks into DRM client functions and remove the old callbacks. The functions instruct the client to poll for changed output or restore the display. The DRM core calls both, the old callbacks and the new client helpers, from the same places. The new functions perform the same operation as before, so there's no change in functionality. Replace all code that initializes or releases fbdev emulation throughout the driver. Instead initialize the fbdev client by a single call to tegra_fbdev_setup() after tegra has registered its DRM device. As in most drivers, tegra's fbdev emulation now acts like a regular DRM client. The fbdev client setup consists of the initial preparation and the hot-plugging of the display. The latter creates the fbdev device and sets up the fbdev framebuffer. The setup performs display hot-plugging once. If no display can be detected, DRM probe helpers re-run the detection on each hotplug event. A call to drm_dev_unregister() releases the client automatically. No further action is required within tegra. If the fbdev framebuffer has been fully set up, struct fb_ops.fb_destroy implements the release. For partially initialized emulation, the fbdev client reverts the initial setup.

drm/tegra: Hide fbdev support behind config option

2023-04-06T10:18:54Z

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: Remove struct tegra_fbdev

2023-04-05T15:06:07Z

Remove struct tegra_fbdev, which is an empty wrapper around struct drm_fb_helper. Use the latter directly. No functional changes. Signed-off-by: Thomas Zimmermann Signed-off-by: Thierry Reding

drm/tegra: Removed fb from struct tegra_fbdev

2023-04-05T15:06:07Z

Fbdev's struct fb_helper stores a pointer to the framebuffer. Remove struct tegra_fbdev.fb, which contains the same value. No functional changes. Signed-off-by: Thomas Zimmermann Signed-off-by: Thierry Reding

drm/tegra: Implement stream ID related callbacks on engines

2022-07-08T14:27:52Z

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

2022-07-08T14:27:52Z

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
