In the function workload_thread(), we invoke complete_current_workload()
to cleanup the just processed workload (workload will be freed there).
So we cannot access workload->req after that. This patch move
complete_current_workload() afterward.

Previous high mem size initialized for vGPU type was too small which caused
failure for some VMs. This trys to take minimal value of 384MB for each VM and
enlarge default high mem size to make guest driver happy.

In function intel_vgpu_emulate_mmio_read, the untracked mmio register is

patch fixes this issue.

The readq and writeq are already offered by drm_os_linux.h. So we can
use them directly whithout dectecting their presence. This patch removed

The current prototype of new_mmio_info() uses void* for parameters read
and write, which are functions with precise calling conventions
(argument types and return type). Write down these conventions in
new_mmio_info() definition.
This has been reported by the following warnings when clang is used to
build the kernel:
drivers/gpu/drm/i915/gvt/handlers.c:124:21: error: pointer type
mismatch ('void *' and 'int (*)(struct intel_vgpu *, unsigned int,
void *, unsigned int)') [-Werror,-Wpointer-type-mismatch]
info->read = read ? read : intel_vgpu_default_mmio_read;
^ ~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/i915/gvt/handlers.c:125:23: error: pointer type
mismatch ('void *' and 'int (*)(struct intel_vgpu *, unsigned int,
void *, unsigned int)') [-Werror,-Wpointer-type-mismatch]
info->write = write ? write : intel_vgpu_default_mmio_write;
^ ~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This allows the compiler to detect that sbi_ctl_mmio_write() returns a
"bool" value instead of an expected "int" one. Fix this.

Analogix_dp_bind() can be called from component framework, which doesn't
guarantee proper runtime PM state of the device during bind operation,
so ensure that device is runtime active before doing any register access.
This ensures that the power domain, to which DP module belongs, is turned
on. While at it, also fix the unbalanced call to phy_power_on() in
analogix_dp_bind() function.
This patch solves the following kernel oops on Samsung Exynos5250 Snow

A few fixes for 4.10.. the first fixes a long-standing logic bug, that
by luck (ie. size of packets written into RB for a submit) wasn't hit
on a3xx/a4xx but was causing intermittent GPU lockups on a5xx. And a
couple other robustness issues that Jordan noticed.
* 'msm-fixes-4.10' of git://people.freedesktop.org/~robclark/linux:
drm/msm: Verify that MSM_SUBMIT_BO_FLAGS are set
drm/msm: Put back the vaddr in submit_reloc()

For every submission buffer object one of MSM_SUBMIT_BO_WRITE
and MSM_SUBMIT_BO_READ must be set (and nothing else). If we
allowed zero then the buffer object would never get queued to
be unreferenced.

Currently the value written to CP_RB_WPTR is calculated on the fly as
(rb->next - rb->start). But as the code is designed rb->next is wrapped
before writing the commands so if a series of commands happened to
fit perfectly in the ringbuffer, rb->next would end up being equal to
rb->size / 4 and thus result in an out of bounds address to CP_RB_WPTR.
The easiest way to fix this is to mask WPTR when writing it to the
hardware; it makes the hardware happy and the rest of the ringbuffer
math appears to work and there isn't any point in upsetting anything.

Revision 2 of LCDC suffers from an issue where a SYNC_LOST error
caused by limited memory bandwidth may leave the picture shifted a
couple pixels to the right.
This issue has not been observed on revision 1, while the recovery
mechanism introduces a different issue, where the END_OF_FRAME
interrupt doesn't fire while drm is waiting for vblanks.
On rev1: recover from sync lost errors by simply clearing the
RASTER_ENABLE bit in the RASTER_CTRL register and re-enabling it
again as is suggested by the datasheet.

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

The drm driver .load() operation is prone to race conditions as it
initializes the driver after registering the device nodes. Its usage is
deprecated, inline it in the probe function and call drm_dev_alloc() and
drm_dev_register() explicitly.
For consistency inline the .unload() handler in the remove function as
well.

Calling drm_vblank_cleanup() in drm_dev_unregister() causes issues with
drivers that have moved away from the .load() and .unload() midlayer.
Those drivers call drm_dev_unregister() as the first operation at unbind
time, before shutting down the device. This results in warnings due to
drm_vblank_cleanup() being called with vblank interrupts still active,
and then to vblank events being sent after cleanup.
Fix the problem by moving vblank cleanup from drm_dev_unregister() to
drm_dev_release() that is guaranteed to be called after drivers shut
down the device.

Instead of going through a complicated private IRQ registration
mechanism, handle the vblank interrupt activation with the standard
drm_crtc_vblank_get() and drm_crtc_vblank_put() mechanism. This will let
the DRM core keep the vblank interrupt enabled as long as needed to
update the frame counter.
