2016-11-14drm/fb-helper: fix segfaults in drm_fb_helper_debug_*Stefan Christ
A drm driver that is implementing fb_debug_enter and fb_debug_leave in struct fb_ops with drm fb helper functions drm_fb_helper_debug_enter and drm_fb_helper_debug_leave must also implement the callback 'mode_set_base_atomic' in struct drm_crtc_helper_funcs. See Documentation/DocBook/kgdb.tmpl. The current implementation will segfault when 'mode_set_base_atomic' is a NULL pointer. Before this patch at least the drm drivers armada, ast, qxl, udl and virtio do not have a 'mode_set_base_atomic' implementation but using drm_fb_helper_debug_(enter|leave). So these drivers may segfault when callbacks fb_debug_(enter|leave) are called. Avoid the issue by just checking for NULL pointers. So all drivers can unconditionally implement fb_debug_(enter|leave) with the drm_fb_helper functions. If callback 'mode_set_base_atomic' is not implemented, the code in drm_fb_helper_debug_(enter|leave) does effectively nothing.

2016-11-14drm: rcar-du: Fix crash in encoder failure error pathLaurent Pinchart
When an encoder fails to initialize the driver prints an error message to the kernel log. The message contains the name of the encoder's DT node, which is NULL for internal encoders. Use the of_node_full_name() macro to avoid dereferencing a NULL pointer, print the output number to add more context to the error, and make sure we still own a reference to the encoder's DT node by delaying the of_node_put() call.

2016-11-12drm: move allocation out of drm_get_format_name()Eric Engestrom
The function's behaviour was changed in 90844f00049e, without changing its signature, causing people to keep using it the old way without realising they were now leaking memory. Rob Clark also noticed it was also allocating GFP_KERNEL memory in atomic contexts, breaking them. Instead of having to allocate GFP_ATOMIC memory and fixing the callers to make them cleanup the memory afterwards, let's change the function's signature by having the caller take care of the memory and passing it to the function. The new parameter is a single-field struct in order to enforce the size of its buffer and help callers to correctly manage their memory.

When we release the shmem backing storage, we make sure that the pages are coherent with the cpu cache. However, our clflush routine was skipping the flush as the object had no pages at release time. Fix this by explicitly flushing the sg_table we are decoupling.

2016-11-11drm/i915: Only wait upon the execution timeline when unlockedChris Wilson
In order to walk the list of all timelines, we currently require the struct_mutex. We are sometimes called prior to the struct_mutex being taken by the caller (i.e !I915_WAIT_LOCKED) in which case we can only trust the global execution timelines (as these are owned by the device). This means in the unlocked phase we can only wait upon the currently executing requests and not all queued.

drm-next Here is the list of fixes that I have for drm/mali-dp. They've been on the mailing lists for a while and merged into linux-next for a few weeks, but due to holiday and travel to Linux Plumbers I did not send the pull request earlier. I don't know if these patches can be pulled into v4.9 still (they will conflict with Ville Syrjälä's cleanup of DRM_ROTATE series that is already in drm-next), but if you do that would be great. * 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld: drm: mali-dp: Clear CVAL when leaving config mode drm/arm: mark symbols static where possible drm: mali-dp: Add support for setting plane's rotation property from userspace. drm: mali-dp: Don't set DRM_PLANE_COMMIT_ACTIVE_ONLY drm: mali-dp: Store internal format and n_planes in plane state drm: mali-dp: Enable alpha blending drm: mali-dp: Refactor plane initialisation arm: mali-dp: Extract mode_config cleanup into malidp_fini drm: mali-dp: Add pitch alignment check for planes drm: mali-dp: Add pitch alignment check function drm: mali-dp: Set the drm->irq_enabled flag to match driver's state. drm: mali-dp: Clear the config_valid flag before using it in wait_event.

2016-11-10drm/i915: Trim the object sg tableTvrtko Ursulin
At the moment we allocate enough sg table entries assuming we will not be able to do any coalescing. But since in practice we most often can, and more so very effectively, this ends up wasting a lot of memory. A simple and effective way of trimming the over-allocated entries is to copy the table over to a new one allocated to the exact size. Experiments on my freshly logged and idle desktop (KDE) showed that by doing this we can save approximately 1 MiB of RAM, or when running a typical benchmark like gl_manhattan I have even seen a 6 MiB saving. More complicated techniques such as only copying the last used page and freeing the rest are left to the reader. v2: * Update commit message. * Use temporary sg_table on stack. (Chris Wilson) v3: * Commit message update. * Comment added. * Replace memcpy with copy assignment.

2016-11-10drm/i915/gvt: add KVMGT supportJike Song
KVMGT is the MPT implementation based on VFIO/KVM. It provides a kvmgt_mpt ops to gvt for vGPU access mediation, e.g. to mediate and emulate the MMIO accesses, to inject interrupts to vGPU user, to intercept the GTT writing and replace it with DMA-able address, to write-protect guest PPGTT table for shadowing synchronization, etc. This patch provides the MPT implementation for GVT, not yet functional due to theabsence of mdev. It's built as kvmgt.ko, depends on vfio.ko, kvm.ko and mdev.ko, and being required by i915.ko. To not introduce hard dependency in i915.ko, we used indirect symbol reference. But that means users have to include kvmgt.ko into init ramdisk if their i915.ko is included.

2016-11-10drm/i915/gvt: refactor intel_gvt_io_emulation_ops to be intel_gvt_opsJike Song
There are currently 4 methods in intel_gvt_io_emulation_ops to emulate CFG/MMIO reading/writing for intel vGPU. A possibly better scope is: add 3 more methods for vgpu create/destroy/reset respectively, and rename the ops to 'intel_gvt_ops', then pass it to the MPT module (say the future kvmgt) to use: they are all methods for external usage.

2016-11-10drm/i915/gvt: allow several MPT methods to be NULLJike Song
Hypervisors are different, the MPT ops is a only superset of all possibly supported hypervisors. There might be other way out of the MPT to achieve same target. e.g. vfio-based kvmgt won't provide map_gfn_to_mfn method to establish guest EPT mapping for aperture, since it will be done in QEMU/KVM, MMIO is also trapped elsewhere, etc. Signed-off-by: Jike Song <jike.song@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

2016-11-10drm/i915/gvt: don't rely on guest PPGTT entry to free old shadow dataBing Niu
On guest writing a PPGTT entry, if it contains value and the old entry is valid, gvt will read it and find & free the corresponding old data for it. However, with the KVM write protection provided by page_track, the guest entry will be written with new value before gvt handling. To avoid that, we should use the shadow entry instead.

2016-11-09drm/i915: Spin until breadcrumb threads are completeChris Wilson
When we need to reset the global seqno on wraparound, we have to wait until the current rbtrees are drained (or otherwise the next waiter will be out of sequence). The current mechanism to kick and spin until complete, may exit too early as it would break if the target thread was currently running. Instead, we must wake up the threads, but keep spinning until the trees have been deleted. In order to appease Tvrtko, busy spin rather than yield().
