2023-03-15drm: Track clients by tgid and not tidTvrtko Ursulin
Thread group id (aka pid from userspace point of view) is a more interesting thing to show as an owner of a DRM fd, so track and show that instead of the thread id. In the next patch we will make the owner updated post file descriptor handover, which will also be tgid based to avoid ping-pong when multiple threads access the fd.

2023-03-14drm/mcde: Do not use dirty GEM FB handlingLinus Walleij
This driver has no way to handle damage, the reason the drm_gem_fb_create_with_dirty() was used was because I had the ambition that the driver would only send out updates to DSI command displays whenever something changed, so as to minimize traffic. It turns out this ambition with command mode isn't working in practice because all the MCDE does is to create a continuous stream of DSI commands and while it is possible to send single frame updates with it, it's not been worthwhile. So we are just setting up continuous updates.

2023-03-14drm/fbdev-dma: Implement fbdev emulation for GEM DMA helpersThomas Zimmermann
Implement fbdev emulation that is optimized for drivers that use DMA helpers. The buffers may no tbe moveable, may not require damage handling and have to be located in system memory. This allows fbdev emulation to operate directly on the buffer and mmap it to userspace. Besides those constraints, the emulation works like in the generic code. As an internal DRM client provides, it receives hotplug, restore and unregister events. The DRM client is independent from the fbdev probing, which runs on the first successful hotplug event. The emulation is part of the DMA helper module and not build unless DMA helpers and fbdev emulation has been configured. Tested with vc4.

2023-03-13drm/cirrus: Store HW format/pitch in primary-plane stateThomas Zimmermann
The hardware settings for color format and pitch are state of the primary plane. Store the values in the primary plane's state structure struct cirrus_primary_plane_state. Adapt all callers. All fields in struct cirrus_device are now considered immutable after initialization. Plane updates consider the difference between the old and the new plane state before updating format or pitch.

2023-03-13drm/cirrus: Introduce struct cirrus_primary_plane_stateThomas Zimmermann
The cirrus driver maintains plane state, format and pitch, in it's device structure. Introduce a plane state for the primary plane to store the values.

2023-03-13drm/cirrus: Inline cirrus_check_size() into primary-plane atomic_checkThomas Zimmermann
Inline the framebuffer size check into the primary plane's atomic_check cirrus_primary_plane_atomic_check(). No functional changes.

2023-03-13drm/cirrus: Test mode against video-memory size in device-wide mode_validThomas Zimmermann
Test a display mode against the available amount of video memory in struct drm_mode_config_funcs.mode_valid, which cirrus implements in cirrus_mode_config_mode_valid(). This helper tests display modes against device-wide limits. Remove the now-obsolete per-CRTC test.

2023-03-13drm/cirrus: Remove size test from cirrus_fb_create()Thomas Zimmermann
The DRM core implements a size check against the mode config's limits when creating a framebuffer. [1] Remove the unnecessary test from cirrus_fb_create() and remove the now-empty function. Create framebuffers with drm_gem_fb_create_with_dirty().

2023-03-13drm/cirrus: Inline cirrus_fb_blit_rect()Thomas Zimmermann
Inline cirrus_fb_blit_rect into its only caller. While at it, update the code to use IOSYS_MAP_INIT_OFFSET(), which is the ideomatic way of initializing struct iosys_map with an offset.
