2017-01-16drm/amdkfd: fix improper return value on errorPan Bian
In function kfd_wait_on_events(), when the call to copy_from_user() fails, the value of return variable ret is 0. 0 indicates success, which is inconsistent with the execution status. This patch fixes the bug by assigning "-EFAULT" to ret when copy_from_user() returns an unexpected value.

2017-01-09dma-fence: Introduce drm_fence_set_error() helperChris Wilson
The dma_fence.error field (formerly known as dma_fence.status) is an optional field that may be set by drivers before calling dma_fence_signal(). The field can be used to indicate that the fence was completed in err rather than with success, and is visible to other consumers of the fence and to userspace via sync_file. This patch renames the field from status to error so that its meaning is hopefully more clear (and distinct from dma_fence_get_status() which is a composite between the error state and signal state) and adds a helper that validates the preconditions of when it is suitable to adjust the error field.

2017-01-09dma-fence: Wrap querying the fence->statusChris Wilson
The fence->status is an optional field that is only valid once the fence has been signaled. (Driver may fill the fence->status with an error code prior to calling dma_fence_signal().) Given the restriction upon its validity, wrap querying of the fence->status into a helper dma_fence_get_status().

2017-01-09dma-fence: Clear fence->status during dma_fence_init()Chris Wilson
As the fence->status is an optional field that may be set before dma_fence_signal() is called to convey that the fence completed with an error, we have to ensure that it is always set to zero on initialisation so that the typical use (i.e. unset) always flags a successful completion.

2017-01-06drm/i915: Drain freed objects for mmap space exhaustionChris Wilson
As we now use a deferred free queue for objects, simply retiring the active objects is not enough to immediately free them and recover their mmap space - we must now also drain the freed object list.

2017-01-06drm/i915: Purge loose pages if we run out of DMA remap spaceChris Wilson
If the DMA remap fails, one cause can be that we have too many objects pinned in a small remapping table, such as swiotlb. (DMA remapping does not trigger the shrinker by itself on its normal failure paths.) So try purging all other objects (using i915_gem_shrink_all(), sparing our own pages as we have yet to assign them to the obj->pages) and try again. If there are no pages to reclaim (and consequently no pages to unmap), the shrinker will report 0 and we fail with -ENOSPC as before.

2017-01-06drm/i915: Fix phys pwrite for struct_mutex-less operationChris Wilson
Since commit fe115628d567 ("drm/i915: Implement pwrite without struct-mutex") the lowlevel pwrite calls are now called without the protection of struct_mutex, but pwrite_phys was still asserting that it held the struct_mutex and later tried to drop and relock it.

2017-01-06drm/i915: Simplify testing for am-I-the-kernel-context?Chris Wilson
The kernel context (dev_priv->kernel_context) is unique in that it is not associated with any user filp - it is the only one with ctx->file_priv == NULL. This is a simpler test than comparing it against dev_priv->kernel_context which involves some pointer dancing. In checking that this is true, we notice that the gvt context is allocating itself a i915_hw_ppgtt it doesn't use and not flagging that its file_priv should be invalid.

Do not process update requests with unmodified parameters. Since the HQVDP command queue is limited to 2, we shall take care of not posting unneeded commands, which would abusively fill the command queue leading to frame update skip. This typically happens when the driver is called with legacy (non-atomic) IOCTL : in that case atomic_update() is called multiple times with the same parameters.
