Finally all the core gem and a lot of drivers are entirely free of dev->struct_mutex depencies, and we can start to have an entirely lockless unref path. To make sure that no one who touches the core code accidentally breaks existing drivers which still require dev->struct_mutex I've made the might_lock check unconditional. While at it de-inline the ref/unref functions, they've become a bit too big. v2: Make it not leak like a sieve. v3: Review from Lucas: - drop != NULL in pointer checks. - fixup copypasted kerneldoc to actually match the functions. v4: Add __drm_gem_object_unreference as a fastpath helper for drivers who abolished dev->struct_mutex, requested by Chris. v5: Fix silly mistake in drm_gem_object_unreference_unlocked caught by intel-gfx CI - I checked for gem_free_object instead of gem_free_object_unlocked ...

Pretty much all of these hasn't seen any action singe 2008 at the very least. Barring the occasional buildfix and DRM-wide refactoring of course. Note: some distributions have stopped shipping their userspace counterparts for a while. Although some still do. Signed-off-by:

The fsl dcu now uses the clk-provider interfaces, which are not available when CONFIG_COMMON_CLK is disabled: drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c: In function 'fsl_dcu_drm_probe': drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c:362:20: error: implicit declaration of function '__clk_get_name' [-Werror=implicit-function-declaration] pix_clk_in_name = __clk_get_name(pix_clk_in); This adds a Kconfig dependency to prevent the driver from being enabled in this case.

Another step in renaming async to nonblocking for atomic commit. Signed-off-by:
-
Maarten Lankhorst authored
This is the first step of renaming async commit to nonblocking commit. The flag passed by userspace is NONBLOCKING, and async has a different meaning for page flips, where it means as soon as possible. Fixing up comments in drm core is done manually, to make sure I didn't miss anything. For drivers, the following cocci script is used to rename bool async to bool nonblock: @@ identifier I =~ "^async"; identifier func; @@ func(..., bool - I + nonblock , ...) { <... - I + nonblock ...> } @@ identifier func; type T; identifier I =~ "^async"; @@ T func(..., bool - I + nonblock , ...); Thanks to Tvrtko Ursulin for the cocci script.

Use the fbdev deferred io support in drm_fb_helper. The (struct fb_ops *)->fb_{fillrect,copyarea,imageblit} functions will now schedule a worker instead of being flushed directly like it was previously (recorded when in atomic).

Noralf Trønnes authored
This adds fbdev deferred io support if CONFIG_FB_DEFERRED_IO is enabled. The driver has to provide a (struct drm_framebuffer_funcs *)->dirty() callback to get notification of fbdev framebuffer changes. If the dirty() hook is set, then fb_deferred_io is set up automatically by the helper. Two functions have been added so that the driver can provide a dirty() function: - drm_fbdev_cma_init_with_funcs() This makes it possible for the driver to provided a custom (struct drm_fb_helper_funcs *)->fb_probe() function. - drm_fbdev_cma_create_with_funcs() This is used by the .fb_probe hook to set a driver provided (struct drm_framebuffer_funcs *)->dirty() function.
