The dpy_reg_mmio_read_x functions directly copy 4 bytes data to the
target address with considering the length. If may cause the target
memory corrupted if the requested length less than 4 bytes. Fix it
for safety even we already have some checking to avoid this happen.
And for convince, the 3 functions are merged.

When host connects a crt screen, linux guest will detect two
screens: crt and dp. This is wrong as linux guest has only
one dp.
In order to avoid guest get host crt screen, we should set
ADPA_CRT_HOTPLUG_MONITOR to none. But MMIO_RO(PCH_ADPA) prevent
from that. So MMIO_DH should be used instead of MMIO_RO.
v2: Clear its staus to none at initialize, so guest don't
get host crt.(Zhangyu)
v3: SKL doesn't have this register, limit it to pre_skl.(xiong)

On BDW, when host physical screen and guest virtual screen aren't on
the same DDI port, guest i915 driver prints the following error and
stop running.
[ 6.775873] BUG: unable to handle kernel NULL pointer dereference

The null pointer is guest intel_crtc_state->shared_dpll which is
setted in haswell_get_ddi_pll(). When guest and host screen are
on different DDI port, host driver won't set PORT_CLK_SET(guest_port),
so haswell_get_ddi_pll() will return null and don't set
pipe_config->shared_dpll, once the following program refernce this
structure, it will print the above error.
This patch set the initial val of guest PORT_CLK_SEL(guest_port) to
LCPLL_810. And guest i915 driver will reset this value according to
guest screen mode.

There are two kinds of locking sequence.
One is in the thread which is started by vfio ioctl to do
the iommu unmapping. The locking sequence is:
down_read(&group_lock) ----> mutex_lock(&cached_lock)
The other is in the vfio release thread which will unpin all
the cached pages. The lock sequence is:
mutex_lock(&cached_lock) ---> down_read(&group_lock)
And, the cache_lock is used to protect the rb tree of the cache
node and doing vfio unpin doesn't require this lock. Move the
vfio unpin out of the cache_lock protected region.
v2:
- use for style instead of do{}while(1). (Zhenyu)

Previous patch (c5f228ef6c drm/mediatek: add *driver_data for different
hardware settings) calls devm_kfree() and then devm_kzalloc() to
reallocate color module data structure. But this reallocation cannnot
guarantee the new address is unchanged, but the caller will use the
old address, which is wrong.
Fix it by separate color module from general components, this patch
separate color module to independent files, like mtk_disp_ovl.c and
mtk_disp_rdma.c do

It was required to explicitly set these parameters to 1, even if the

Drop the KCQ disabling via KIQ. We disable the MEC shortly

Doing so seems to leave the MEC in a bad way.

amd_powerplay_destroy() expects a handle pointing to a struct pp_instance.
On chips without PowerPlay, pp_handle points to a struct amdgpu_device. The
resulting attempt to kfree() fields of the wrong struct ends in fire:

commit 2889caa92321 ("drm/i915: Eliminate lots of iterations over the
execobjects array") jiggled around the error handling and replace a test
that we cleaned up properly after ourselves with an assertion. That
assertion failed because in the release function (moments after the
assertion) we were indeed forgetting to mark the vma as cleared. The
consequence was when testing an invalid relocation address, we would try
to release the vma twice (following the couple of attempts to verify the
address) and on the second release notice that the first release was
incomplete.
Testcase: igt/gem_reloc_overflow/invalid-address

i915_vma_move_to_active() takes the execobject flags and not a boolean!
Instead of passing EXEC_OBJECT_WRITE we passed true [i.e.
EXEC_OBJECT_NEEDS_FENCE] causing us to start tracking the
vma->last_fence access and since we forgot to clear that on unbinding,
we caused a use-after-free.

This reverts commit cd34db4a526c (drm/etnaviv: Remove manual call to
reservation_object_test_signaled_rcu before wait), as the patch to turn
reservation_object_wait_timeout_rcu() into
reservation_object_test_signaled_rcu() with a 0 timeout has been reverted.
This causes the driver to call into the fence wait, even with a timeout of 0
The etnaviv BO cache depends on ETNA_PREP_NOSYNC to be wait-free, even if
the BO has attached fences, so restore the behaviour for this flag.
