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: -

Debug logging in this function does not provide any information apart that the userspace is calling an ioctl on the connector. There is not any info on the connector provided at all and since there are other ioctls userspace typically calls which do log useful things about the same connectors, remove this one to make things a little bit more readable when KMS debugging is turned on.
