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).

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.

Export fb_deferred_io_mmap so drivers can change vma->vm_page_prot. When the framebuffer memory is allocated using dma_alloc_writecombine() instead of vmalloc(), I get cache syncing problems on ARM. This solves it: static int drm_fbdev_cma_deferred_io_mmap(struct fb_info *info, struct vm_area_struct *vma) { fb_deferred_io_mmap(info, vma); vma->vm_page_prot = pgprot_writecombine(vma->vm_page_prot); return 0; } Could this have been done in the core? Drivers that don't set (struct fb_ops *)->fb_mmap, gets a call to fb_pgprotect() at the end of the default fb_mmap implementation (drivers/video/fbdev/core/fbmem.c). This is an architecture specific function that on many platforms uses pgprot_writecombine(), but not on all. And looking at some of the fb_mmap implementations, some of them sets vm_page_prot to nocache for instance, so I think the safest bet is to do this in the driver and not in the fbdev core. And we can't call fb_pgprotect() from fb_deferred_io_mmap() either because we don't have access to the file pointer that powerpc needs.

This adds deferred io support to drm_fb_helper. The fbdev framebuffer changes are flushed using the callback (struct drm_framebuffer *)->funcs->dirty() by a dedicated worker ensuring that it always runs in process context. For those wondering why we need to be able to handle atomic calling contexts: Both panic paths and cursor code and fbcon blanking can run from atomic.

Now that drm_fb_helper gets deferred io support, the drm_fb_helper_sys_{fillrect,copyarea,imageblit} functions will schedule a worker that will call the (struct drm_framebuffer *)->funcs->dirty() function. This will break this driver so use the sys_{fillrect,copyarea,imageblit} functions directly. Signed-off-by:
