Static checker gave warning on: drivers/gpu/drm/i915/gvt/edid.c:506 intel_gvt_i2c_handle_aux_ch_write() warn: odd binop '0x0 & 0xff' We try to return ACK for I2C reply which is defined with 0.

2016-11-14drm/i915/gvt: fix crash in vgpu_reset_execlistDu, Changbin
We initiate vgpu->workload_q_head via for_each_engine macro which may skip unavailable engines. So we should follow this rule anywhere. The function intel_vgpu_reset_execlist is not aware of this. Kernel crash when touch a uninitiated vgpu->workload_q_head[x]. Let's fix it by using for_each_engine_masked and skip unavailable engine ID. Meanwhile rename ring_bitmap to general name engine_mask. v2: remove unnecessary engine activation check (zhenyu) Signed-off-by: Du, Changbin <changbin.du@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

2016-11-14drm/i915/gvt: fix deadlock in workload_threadPei Zhang
It's a classical abba type deadlock when using 2 mutex objects, which are gvt.lock(a) and drm.struct_mutex(b). Deadlock happens in threads: 1. intel_gvt_create/destroy_vgpu: P(a)->P(b) 2. workload_thread: P(b)->P(a) Fix solution is align the lock acquire sequence in both threads. This patch choose to adjust the sequence in workload_thread function. This fixed lockup symptom for guest-reboot stress test. v2: adjust sequence in workload_thread based on zhenyu's suggestion. adjust sequence in create/destroy_vgpu function. v3: fix to still require struct_mutex for dispatch_workload() Signed-off-by: Pei Zhang <pei.zhang@intel.com> [zhenyuw: fix unused variables warnings.] Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>
2016-11-14drm/gma500: use DRM_FB_HELPER_DEFAULT_OPS for fb_opsStefan Christ
This refactoring leads to real functional changes in the driver. Now the struct psbfb_ops implements two additional members: .fb_setcmap = drm_fb_helper_setcmap, .fb_pan_display = drm_fb_helper_pan_display, and the struct psbfb_roll_ops implements one additional member: .fb_setcmap = drm_fb_helper_setcmap, and the struct psbfb_unaccel_ops implements two additional members: .fb_setcmap = drm_fb_helper_setcmap, .fb_pan_display = drm_fb_helper_pan_display, These changes are not tested.

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.

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.
