* drm/udl: Use drm_fb_helper deferred_io supportNoralf Trønnes2016-05-022-136/+6
| | | | | | | | | | | | | | | 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 patch has only been compile tested.

* drm/udl: Change drm_fb_helper_sys_*() calls to sys_*()Noralf Trønnes2016-05-021-3/+3
| | | | | | | | | | | | | 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.

* dma-buf, drm, ion: Propagate error code from dma_buf_start_cpu_access()Chris Wilson2016-03-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers, especially i915.ko, can fail during the initial migration of a dma-buf for CPU access. However, the error code from the driver was not being propagated back to ioctl and so userspace was blissfully ignorant of the failure. Rendering corruption ensues. Whilst fixing the ioctl to return the error code from dma_buf_start_cpu_access(), also do the same for dma_buf_end_cpu_access(). For most drivers, dma_buf_end_cpu_access() cannot fail. i915.ko however, as most drivers would, wants to avoid being uninterruptible (as would be required to guarrantee no failure when flushing the buffer to the device). As userspace already has to handle errors from the SYNC_IOCTL, take advantage of this to be able to restart the syscall across signals. This fixes a coherency issue for i915.ko as well as reducing the uninterruptible hold upon its BKL, the struct_mutex.

| | | | | | | | | | | | | | | | | This patch removes range-based information used for optimizations in begin_cpu_access and end_cpu_access. We don't have any user nor implementation using range-based flush. It seems a consensus that if we ever want something like that again (or even more robust using 2D, 3D sub-range regions) we can use the upcoming dma-buf sync ioctl for such.

* drm: Introduce drm_fb_helper_prepare()Thierry Reding2014-07-081-1/+2
| | | | | | | | | | | | | | | | | | | | | To implement hotplug detection in a race-free manner, drivers must call drm_kms_helper_poll_init() before hotplug events can be triggered. Such events can be triggered right after any of the encoders or connectors are initialized. At the same time, if the drm_fb_helper_hotplug_event() helper is used by a driver, then the poll helper requires some parts of the FB helper to be initialized to prevent a crash. At the same time, drm_fb_helper_init() requires information that is not necessarily available at such an early stage (number of CRTCs and connectors), so it cannot be used yet. Add a new helper, drm_fb_helper_prepare(), that initializes the bare minimum needed to allow drm_kms_helper_poll_init() to execute and any subsequent hotplug events to be processed properly.

Given that the default mapping_gfp_mask() is GFP_HIGHUSER, it is _very_ unlikely that anyone will ever make use of that parameter. In fact, all drivers currently pass redundant flags or 0. This patch removes the 'gfp' parameter. The only reason to keep it is to remove flags like __GFP_WAIT. But in its current form, it can only be used to add flags. So to remove __GFP_WAIT, you'd have to drop it from the mapping_gfp_mask, which again is stupid as this mask is used by shmem-core for other allocations, too. If any driver ever requires that parameter, we can introduce a new helper that takes the raw 'gfp' parameter. The caller'd be responsible to combine it with mapping_gfp_mask() in a suitable way. The current drm_gem_get_pages() helper would then simply use mapping_gfp_mask() and call the new helper. This is what shmem_read_mapping_pages{_gfp,} does right now. Moreover, the gfp-zone flag-usage is not obvious: If you pass a modified zone, shmem core will WARN() or even BUG(). In other words, the following must be true for 'gfp' passed to shmem_read_mapping_pages_gfp(): gfp_zone(mapping_gfp_mask(mapping)) == gfp_zone(gfp) Add a comment to drm_gem_read_pages() explaining that constraint.

* drm: Add separate Kconfig option for fbdev helpersDaniel Vetter2013-10-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | For drivers which might want to disable fbdev legacy support. Select the new option in all drivers for now, so this shouldn't result in any change. Drivers need some work anyway to make fbdev support optional (if they have it implemented, that is), so the recommended way to expose this is by adding per-driver options. At least as long as most drivers don't support disabling the fbdev support. v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm driver can already take advantage of this, which allows us to build msm without any fbdev depencies in the kernel! v3: Move the MODULE_* stuff from the fbdev helper file to drm_crtc_helper.c.
