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: Lukas Wunner <lukas@wunner.de> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/5031860caad67faa0f1be5965331ef048a311a01.1465383212.git.lukas@wunner.de

This patch adds support for extending the pread/pwrite functionality for objects not backed by shmem. The access will be made through gtt interface. This will cover objects backed by stolen memory as well as other non-shmem backed objects. v2: Drop locks around slow_user_access, prefault the pages before access (Chris) v3: Rebased to the latest drm-intel-nightly (Ankit) v4: Moved page base & offset calculations outside the copy loop, corrected data types for size and offset variables, corrected if-else braces format (Tvrtko/kerneldocs) v5: Enabled pread/pwrite for all non-shmem backed objects including without tiling restrictions (Ankit) v6: Using pwrite_fast for non-shmem backed objects as well (Chris) v7: Updated commit message, Renamed i915_gem_gtt_read to i915_gem_gtt_copy, added pwrite slow path for non-shmem backed objects (Chris/Tvrtko) v8: Updated v7 commit message, mutex unlock around pwrite slow path for non-shmem backed objects (Tvrtko) v9: Corrected check during pread_ioctl, to avoid shmem_pread being called for non-shmem backed objects (Tvrtko) v10: Moved the write_domain check to needs_clflush and tiling mode check to pwrite_fast (Chris) v11: Use pwrite_fast fallback for all objects (shmem and non-shmem backed), call fast_user_write regardless of pagefault in previous iteration v12: Use page-by-page copy for slow user access too (Chris) v13: Handled EFAULT, Avoid use of WARN_ON, put_fence only if whole obj pinned (Chris) v14: Corrected datatypes/initializations (Tvrtko) Testcase: igt/gem_stolen, igt/gem_pread, igt/gem_pwrite Signed-off-by: Ankitprasad Sharma <ankitprasad.r.sharma@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1465548783-19712-1-git-send-email-ankitprasad.r.sharma@intel.com

In pwrite_fast, map an object page by page if obj_ggtt_pin fails. First, we try a nonblocking pin for the whole object (since that is fastest if reused), then failing that we try to grab one page in the mappable aperture. It also allows us to handle objects larger than the mappable aperture (e.g. if we need to pwrite with vGPU restricting the aperture to a measely 8MiB or something like that). v2: Pin pages before starting pwrite, Combined duplicate loops (Chris) v3: Combined loops based on local patch by Chris (Chris) v4: Added i915 wrapper function for drm_mm_insert_node_in_range (Chris) v5: Renamed wrapper function for drm_mm_insert_node_in_range (Chris) v5: Added wrapper for drm_mm_remove_node() (Chris) v6: Added get_pages call before pinning the pages (Tvrtko) Added remove_mappable_node() wrapper for drm_mm_remove_node() (Chris) v7: Added size argument for insert_mappable_node (Tvrtko) v8: Do not put_pages after pwrite, do memset of node in the wrapper function (insert_mappable_node) (Chris) v9: Rebase (Ankit) Signed-off-by: Ankitprasad Sharma <ankitprasad.r.sharma@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Introduced a new vm specfic callback insert_page() to program a single pte in ggtt or ppgtt. This allows us to map a single page in to the mappable aperture space. This can be iterated over to access the whole object by using space as meagre as page size. v2: Added low level rpm assertions to insert_page routines (Chris) v3: Added POSTING_READ post register write (Tvrtko) v4: Rebase (Ankit) v5: Removed wmb() and FLUSH_CTL from insert_page, caller to take care of it (Chris) v6: insert_page not working correctly without FLSH_CNTL write, added the write again.

The atomic version of intel_pre_plane_update did not check for HAS_GMCH_DISPLAY before calling intel_set_memory_cxsr(). While this doesn't cause any issues on its own (it will return without doing anything if the hardware doesn't have the required feature), the drm_wait_one_vblank() that is needed if memory self-refresh is disabled introduces an unnecessary delay in the suspend path. In cases where i915 is on the critical path it means that we slow down suspend by 16.8ms on platforms that don't need to disable memory self-refresh.

Apparently some CHV boards failed to hook up the port presence straps for HDMI ports as well (earlier we assumed this problem only affected eDP ports). So let's check the VBT in addition to the strap, and if either one claims that the port is present go ahead and register the relevant connector. While at it, change port D to register DP before HDMI as we do for ports B and C since commit 457c52d8 ("drm/i915: Only ignore eDP ports that are connected") Also print a debug message when we register a HDMI connector to aid in diagnosing missing/incorrect ports. We already had such a print for DP/eDP. v2: Improve the comment in the code a bit, note the port D change in the commit message Cc: Radoslav Duda <radosd@radosd.com> Tested-by: Radoslav Duda <radosd@radosd.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=96321Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1464945463-14364-1-git-send-email-ville.syrjala@linux.intel.comReviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
