Instead of using the dma_buf functionality for GEM CMA, we can use prime helpers if we can provide low-level hook functions for GEM CMA. Signed-off-by:

Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next This is final pull request for 3.11. This resolves some memory leak issues, and includes some code and dt document file cleanups; just removed unnecessary descriptions. And the patch work for enhancing hdmiphy driver isn't in progress so this patch may go to 3.12. * 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: drm/exynos: remove duplicated error routine and unnecessary assign drm/exynos: fix pages allocation size in lowlevel_buffer_allocate drm/exynos: use drm_calloc_large when allocates pointer array drm/exynos: add error check routine in exynos_drm_open drm/exynos: initialize the buf_num in vp_video_buffer drm/exynos: remove dead code in vidi_power_on drm/exynos: fix not to remain exynos_gem_obj as a leak of/documentation: Update hpd gpio property for exynos_hdmi

Adds 3 features that UMS had to the KMS driver. dynamic resizing - resizing remote-viewer makes guest resize multiple crtcs - remote-viewer can access > 1 crtc. suspend/resume/hibernate: guests can do suspend/resume/hibernate now. * 'qxl-next' of git://people.freedesktop.org/~airlied/linux: qxl: use drm helper hotplug support qxl: add suspend/resume/hibernate support. qxl: add fb and ttm entry points for use by suspend/resume. qxl: add ring prep code for s/r qxl: prepare memslot code for suspend/resume qxl: split monitors_config object creation out. drm/qxl: set time on drawables from userspace drm/qxl: add support for > 1 output drm/qxl: make dynamic resizing work properly.

This uses the helper to deal with hotplug so fbdev gets included. Signed-off-by: -

This adds suspend/resume and hibernate support for the KMS driver. it evicts all the objects, turns off the outputs, and waits for the hw to go idle, On resume, it resets the memslots, rings, monitors object and forces modeset. Signed-off-by: -

This adds support for a default of 4 heads, with a command line parameter to change the default number. It also overhauls the modesetting code to handle this case properly, and send the correct things to the hardware at the right time. Signed-off-by: -

qxl has a feature to allow the userspace driver do arbitrary resizes when the viewer resizes, this fixes it by removing unnecessary code from the kernel side. Signed-off-by:

There were duplicated error handling routines during allocating pages in lowlevel_buffer_allocate() and g2d_userptr_get_dma_addr(). Also unnecessary NULL assignments for variable used not any more are removed from g2d_userptr_get_dma_addr() and g2d_userptr_put_dma_addr(). Signed-off-by:

When IOMMU is not supported, buf->pages has to be allocated to assign the result of phys_to_page() which return type is struct page *. So it is sufficient to allocate buf->pages with the size of multiple struct page pointers. Signed-off-by:

The buf_num in vp_video_buffer() should be 1 or 2, but it is not initialized, and only set to 2 in NV12M or NV12MT cases. So this patch initializes the buf_num with 1 as default. Signed-off-by:

The exynos_drm_gem_create() only calls drm_gem_object_release() when exynos_drm_alloc_buf() is failed, and exynos_gem_obj remains as a leak, which is allocated in exynos_drm_gem_init(). So this patch fixes it not to remain as a leak. Signed-off-by:

There are missing parts to handle error in drm_open_helper(). The priv->minor, assigned by idr_find() which can return NULL, should be checked whether it is NULL or not before referencing it. put_pid(), drm_gem_release(), and drm_prime_destory_file_private() should be called when error happens after their pair functions are called. If an error occurs after executing dev->driver->open() which allocates driver specific per-file private data, then the private data should be released. Signed-off-by:

If raw_edid of drm_edid_block_vaild() is null, it will crash, so checking in bad label is removed and instead assertion is added at the top of the function. The type of return for the function is bool, so it fixes to return true and false instead of 1 and 0. Signed-off-by:

Convert drivers/gpu/drm class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, drm class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the drm class. drm_class_suspend() hook calls driver legacy ops with the state information. e.g: drm_class_suspend() calls into driver suspend routines via drm_dev->driver->suspend(drm_dev, state). Once drm_class_suspend() is converted to dev_pm_ops, it will no longer have access to pm_transition which it has to pass into driver legacy suspend calls. A new freeze and suspend hooks are added to address the not having access to the state information. The new freeze and suspend hooks simply call __drm_class_suspend() with the appropriate pm state information. __drm_class_suspend() is the original suspend hook with a new name. Signed-off-by:

Merge tag 'drm-intel-fixes-2013-07-03' of git://people.freedesktop.org/~danvet/drm-intel into drm-next Pile of fixes for 3.11. A bit large in patch count, but that's simply due to two fixes being split up into really small parts. Also I've included a few more vlv patches than I'd have included for other platforms. But since vlv is officially supported for the first time only in 3.11 that shouldn't result in unbearable risks. Highlights: - ghost eDP fixes for hsw from Paulo - fix PCH detection in virtualized enviroments (Rui Guo) - duct-tape dma sg construction when swiotlb is in use (Konrad), dupe with a patch in your drm-fixes branch - fix sdvo hotplug on i965g - tune down a bunch of dmesg ERRORs which can be hit under normal conditions - detect invalid pitches for tiled scanout buffers (Chris) - a pile of vlv fixes from Ville: rps improvements, fixes for the dpll LPF, fixup the sprite mmio offsets - fix context size on hsw (Ben) - locking fixes for the hotplug code, specifically the storm handling - fix get_config on CPT (Xiong Zhang) - Fix the domain tracking when an unlocked seqno wait was interrupt (Chris), this seems to explain tons of little corruption bugs in the ddx. Chris also added a nice igt to exercise this. - work around stack-corrupting vnsprintf in our error state dumper * tag 'drm-intel-fixes-2013-07-03' of git://people.freedesktop.org/~danvet/drm-intel: (39 commits) drm/i915: Don't try to tear down the stolen drm_mm if it's not there drm/i915: Break up the large vsnprintf() in print_error_buffers() drm/i915: Refactor the wait_rendering completion into a common routine drm/i915: Only clear write-domains after a successful wait-seqno drm/i915: correct intel_dp_get_config() function for DevCPT drm/i915: fix hpd interrupt register locking drm/i915: fold the no-irq check into intel_hpd_irq_handler drm/i915: fold the queue_work into intel_hpd_irq_handler drm/i915: fold the hpd_irq_setup call into intel_hpd_irq_handler drm/i915: s/hotplug_irq_storm_detect/intel_hpd_irq_handler/ drm/i915: close tiny race in the ilk pcu even interrupt setup drm/i915: fix locking around ironlake_enable|disable_display_irq drm/i915: Fix context sizes on HSW drm/i915: Fix VLV sprite register offsets Revert "drm/i915: Don't use the HDMI port color range bit on Valleyview" drm/i915: s/LFP/LPF in DPIO PLL register names drm/i915: Fix VLV PLL LPF coefficients for DAC drm/i915: Jump to at least RPe on VLV when increasing the GPU frequency drm/i915: Don't increase the GPU frequency from the delayed VLV rps timer drm/i915: GEN6_RP_INTERRUPT_LIMITS doesn't seem to exist on VLV ...

In commit da34242e Author: YoungJun Cho <yj44.cho@samsung.com> Date: Wed Jun 26 10:21:42 2013 +0900 drm/prime: add return check for dma_buf_fd the failure case handling was fixed up. But in the case when we already had the buffer exported it changed the return value: Previously we've return 0 on success, now we return the fd. This ABI change has been caught by i-g-t/prime_self_import/with_one_bo.
