* MAINTAINERS: Add a bunch of legacy (UMS) DRM driversEmil Velikov2016-05-031-0/+29
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* drm/fb-cma-helper: Add fb_deferred_io supportNoralf Trønnes2016-05-022-12/+180
| | | | | | | | | | | | | | | | | | | | | | 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.

* fbdev: fb_defio: Export fb_deferred_io_mmapNoralf Trønnes2016-05-022-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* drm/fb-helper: Add fb_deferred_io supportNoralf Trønnes2016-05-023-1/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | amdgpu gained dev->struct_mutex usage, and that's because it's walking the dev->filelist list. Protect that list with it's own lock to take one more step towards getting rid of struct_mutex usage in drivers once and for all. While doing the conversion I noticed that 2 debugfs files in i915 completely lacked appropriate locking. Fix that up too. v2: don't forget to switch to drm_gem_object_unreference_unlocked.

Note that the entirety of the legacy addmap interface is now protected by DRIVER_MODESET. Note that just auditing kernel code is not enough, since userspace loves to set up legacy maps on it's own for various things - with ums userspace and kernel space share control over resources. v2: Also add a DRIVER_* check like for all other maps functions to really short-circuit the code. And give drm_legacy_rmmap used by the dev unregister code the same treatment. v3: - remove redundant return; (Alex, Chris) - don't special case nouveau with DRIVER_KMS_LEGACY_CONTEXT. v4: Again special case nouveau. The problem is not directly in the ddx, but that it calls dri1 functions from the X server. And those do call drmAddMap.
