Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI as a convenience. Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up through the atomic API, but realizing that userspace is likely to take shortcuts and assume that the enum values are what is sent over the wire. As a result these defines are provided purely as a convenience to userspace applications. Changes since v3: - Switched away from past tense in comments - Add define name change to previously mis-spelled DRM_REFLECT_X comment - Improved the comment for the DRM_MODE_REFLECT_<axis> comment Changes since v2: - Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_ - Fix compilation errors - Changed comment formatting - Deduplicated comment lines - Clarified DRM_MODE_PROP_REFLECT_ comment Changes since v1: - Moved defines from drm.h to drm_mode.h - Changed define prefix from DRM_ to DRM_MODE_PROP_ - Updated uses of the defines to the new prefix - Removed include from drm_rect.c - Stopped using the BIT() macro Signed-off-by: NRobert Foss <robert.foss@collabora.com> Reviewed-by: NEmil Velikov <emil.velikov@collabora.com> Reviewed-by: NSinclair Yeh <syeh@vmware.com> Acked-by: NLiviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20170519205017.23307-2-robert.foss@collabora.com

We do not need the BKL struct_mutex in order to allocate a GEM object, nor to create the framebuffer, so resist the temptation to take the BKL willy nilly.

Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates.

It has been suggested that having per-plane modifiers is making life more difficult for userspace, so let's just retire modifier[1-3] and use modifier[0] to apply to the entire framebuffer. Obviosuly this means that if individual planes need different tiling layouts and whatnot we will need a new modifier for each combination of planes with different tiling layouts. For a bit of extra backwards compatilbilty the kernel will allow non-zero modifier[1+] but it require that they will match modifier[0]. This in case there's existing userspace out there that sets modifier[1+] to something non-zero with planar formats.

If the fbdev probing fails, and in our error path we fail to clear the dev_priv->fbdev, then we can try and use a dangling fbdev pointer, and in particular a NULL fb. This could also happen in pathological cases where we try to operate on the fbdev prior to it being probed.

Ringbuffers are now being written to either through LLC or WC paths, so treating them as simply iomem is no longer adequate. However, for the older !llc hardware, the hardware is documentated as treating the TAIL register update as serialising, so we can relax the barriers when filling the rings (but even if it were not, it is still an uncached register write and so serialising anyway.). For simplicity, let's ignore the iomem annotation. v2: Remove iomem from ringbuffer->virtual_address v3: And for good measure add iomem elsewhere to keep sparse happy Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> #v2 Link: http://patchwork.freedesktop.org/patch/msgid/1469005202-9659-8-git-send-email-chris@chris-wilson.co.uk Link: http://patchwork.freedesktop.org/patch/msgid/1469017917-15134-7-git-send-email-chris@chris-wilson.co.uk

Since the suspend_work can arm itself if the console_lock() is currently held elsewhere, simply calling flush_work() doesn't guarantee that the work is idle upon return.

During lastclose, we call intel_fbdev_restore_mode() to switch back to the fbcon configuration on return to VT. However, if we have not yet finished the asynchronous fbdev initialisation, the current mode will be invalid and trigger WARNs upon application. Serialise with the outstanding initialisation if the first application exits quickly. Note that to hit this in practice requires using an unregistered async_domain as otherwise modprobe will force a full synchronisation prior to init() completing. v2: Reuse comment explaining the +1 by refactoring the wait on fbdev sync in the previous patch.

During cleanup we have to synchronise with the async task we are using to initialise and register our fbdev. Currently, we are using a full synchronisation on the global domain, but we can restrict this to just synchronising up to our task if we remember our cookie. Whilst there, streamline the function parameters. v2: async_synchronize_cookie() takes an exclusive upper bound, to synchronize with our task we have to pass in the next cookie. v3: Drop premature disregarding of the active cookie (we need to wait until the task is complete before continuing in the teardown). v4: Refactor waiting on async to incorporate a comment explaining why we need the +1.

Calling drm_framebuffer_unregister_private() in intel_fbdev_destroy() is superfluous because the framebuffer will subsequently be unregistered by drm_framebuffer_free() when unreferenced in drm_framebuffer_remove(). The call is a leftover, when it was introduced by commit 36206361 ("drm: revamp framebuffer cleanup interfaces"), struct intel_framebuffer was still embedded in struct intel_fbdev rather than being a pointer as it is today, and drm_framebuffer_remove() wasn't used yet. As a bonus, the ID of the framebuffer is no longer 0 in the debug log: Before: [ 39.680874] [drm:drm_mode_object_unreference] OBJ ID: 0 (3) [ 39.680878] [drm:drm_mode_object_unreference] OBJ ID: 0 (2) [ 39.680884] [drm:drm_mode_object_unreference] OBJ ID: 0 (1) After: [ 102.504649] [drm:drm_mode_object_unreference] OBJ ID: 45 (3) [ 102.504651] [drm:drm_mode_object_unreference] OBJ ID: 45 (2) [ 102.504654] [drm:drm_mode_object_unreference] OBJ ID: 45 (1) Signed-off-by: NLukas Wunner <lukas@wunner.de> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/5031860caad67faa0f1be5965331ef048a311a01.1465383212.git.lukas@wunner.de

Drivers transitioning to atomic might not yet want to enable full DRIVER_ATOMIC support when it's not entirely working. But using atomic internally makes a lot more sense earlier. Instead of spreading such flags to more places I figured it's simpler to just check for mode_config->funcs->atomic_commit, and use atomic paths if that is set. For the only driver currently transitioning (i915) this does the right thing.
