710931c2be drm/amd/powerplay: wrong control mode cause the fan spins faster unnecessarily
The fan control mode can either be FDO_PWM_MODE_STATIC or FDO_PWM_MODE_STATIC_RPM.
Setting it as AMD_FAN_CTRL_AUTO will cause the fan spin faster wrongly.

This can be reproduced by:
'# cat /sys/class/hwmon/hwmon0/pwm1
   38
'# cat /sys/class/hwmon/hwmon0/pwm1_enable
   2
'# echo "2" > /sys/class/hwmon/hwmon0/pwm1_enable
'# cat /sys/class/hwmon/hwmon0/pwm1
   122
The fan speed get faster wrongly even with its original mode echo back.

e2a8e99964 drm/amdkfd: Avoid calling amd_iommu_unbind_pasid() when suspending
When kfd suspending on APU, we do not need to call
amd_iommu_unbind_pasid(), because pasid will be unbound automatically
when power goes off.

On the other hand, calling amd_iommu_unbind_pasid() will trigger
kfd_process_iommu_unbind_callback() if the process is not terminating.
By design, kfd_process_iommu_unbind_callback() should only be called
for process terminating. So we would rather not to call
amd_iommu_unbind_pasid() when suspending.

This is an extension of Commit 7c20d213dd ("drm/vmwgfx: Work
around mode set failure in 2D VMs")

With Wayland desktop and atomic mode set, during the mode setting
process there is a moment when two framebuffer sized surfaces
are being pinned.  This was not an issue with Xorg.

Since this only happens during a mode change, there should be no
performance impact by increasing allowable mem_size.

bb5cf33863 drm/i915: Check incoming alignment for unfenced buffers (on i915gm)
In case the object has changed tiling between calls to execbuf, we need
to check if the existing offset inside the GTT matches the new tiling
constraint. We even need to do this for "unfenced" tiled objects, where
the 3D commands use an implied fence and so the object still needs to
match the physical fence restrictions on alignment (only required for
gen2 and early gen3).

In commit 2889caa923 ("drm/i915: Eliminate lots of iterations over
the execobjects array"), the idea was to remove the second guessing and
only set the NEEDS_MAP flag when required. However, the entire check
for an unusable offset for fencing was removed and not just the
secondary check. I.e.

	/* avoid costly ping-pong once a batch bo ended up non-mappable */
        if (entry->flags & __EXEC_OBJECT_NEEDS_MAP &&
            !i915_vma_is_map_and_fenceable(vma))
                return !only_mappable_for_reloc(entry->flags);

was entirely removed as the ping-pong between execbuf passes was fixed,
but its primary purpose in forcing unaligned unfenced access to be
rebound was forgotten.

This patch fixes the following soft lockup:
  BUG: soft lockup - CPU#0 stuck for 23s! [weston:307]

On weston idle-timeout the IP is powered down and reset
asserted. On weston resume we get a massive vblank
IRQ storm due to the LDI registers having lost some state.

This state loss is caused by ade_crtc_atomic_begin() not
calling ade_ldi_set_mode(). With this patch applied
resuming from Weston idle-timeout works well.

4f626a4ac8 drm/radeon: fix atombios on big endian
The function for byteswapping the data send to/from atombios was buggy for
num_bytes not divisible by four. The function must be aware of the fact
that after byte-swapping the u32 units, valid bytes might end up after the
num_bytes boundary.

This patch was tested on kernel 3.12 and allowed us to sucesfully use
DisplayPort on and Radeon SI card. Namely it fixed the link training and
EDID readout.

The function is patched both in radeon and amd drivers, since the functions
and the fixes are identical.

To acquire all modeset locks requires a ww_ctx to be allocated. As this

required (and complex untested error handling) to the legacy drivers, we
simply assume that the allocation succeeds. At present, it relies on the
too-small-to-fail rule, but syzbot found that by injecting a failure
here we would hit the WARN. Document that this allocation must succeed

7c838e2a9b drm/i915/edp: read edp display control registers unconditionally
Per my reading of the eDP spec, DP_DPCD_DISPLAY_CONTROL_CAPABLE bit in
DP_EDP_CONFIGURATION_CAP should be set if the eDP display control
registers starting at offset DP_EDP_DPCD_REV are "enabled". Currently we
check the bit before reading the registers, and DP_EDP_DPCD_REV is the
only way to detect eDP revision.

Turns out there are (likely buggy) displays that require eDP 1.4+
features, such as supported link rates and link rate select, but do not
have the bit set. Read the display control registers
unconditionally. They are supposed to read zero anyway if they are not
supported, so there should be no harm in this.

This fixes the referenced bug by enabling the eDP version check, and
thus reading of the supported link rates. The panel in question has 0 in
DP_MAX_LINK_RATE which is only supported in eDP 1.4+. Without the
supported link rates method we default to RBR which is insufficient for
the panel native mode. As a curiosity, the panel also has a bogus value
of 0x12 in DP_EDP_DPCD_REV, but that passes our check for >= DP_EDP_14
(which is 0x03).

8777b927b9 drm/i915: Do not rely on wm preservation for ILK watermarks
The original intent was to preserve watermarks as much as possible
in intel_pipe_wm.raw_wm, and put the validated ones in intel_pipe_wm.wm.

It seems this approach is insufficient and we don't always preserve
the raw watermarks, so just use the atomic iterator we're already using
to get a const pointer to all bound planes on the crtc.

713946d16f drm/i915: Cancel the modeset retry work during modeset cleanup
During modeset cleanup on driver unload we may have a pending
hotplug work. This needs to be canceled early during the teardown
so that it does not fire after we have freed the connector.
We do this after drm_kms_helper_poll_fini(dev) since this might
trigger modeset retry work due to link retrain and before
intel_fbdev_fini() since this work requires the lock from fbdev.

If this is not done we may see something like:

18075d0d48 drm/msm/mdp5: Don't use async plane update path if plane visibility changes
When a plane moves out of bounds (i.e, outside the crtc clip region), the
plane state's "visible" parameter changes to false. When this happens, we
(a) release the hwpipe resources away from it, and
(b) unstage the corresponding hwpipe(s) from the Layer Mixers in the CRTC.

(a) requires use to acquire the global atomic state and assign a new
hwpipe. (b) requires us to re-configure the Layer Mixer, which is done in
the CRTC. We don't want to do these things in the async plane update path,
so return an error if the new state's "visible" isn't the same as the
current state's "visible".

aa649e875d drm/msm/mdp5: mdp5_crtc: Restore cursor state only if LM cursors are enabled
MDP5 on newer SoCs support cursor planes (i.e, cursor SSPPs). They are a
separate entity unlike the cursors within LM.

Do not try to restore the MDP5 LM cursor registers, or the corresponding
CTL bits if we are not using LM cursors.

Also, since we've introduced a new variable 'lm_cursor_enabled', we can
now use it to avoid creating a different sets of crtc_funcs for CRTCs
with LM cursors and CRTCs with cursor planes.

b148928010 drm/msm/mdp5: Update mdp5_pipe_assign to spit out both planes
We currently call mdp5_pipe_assign() twice to assign the left and right
hwpipes for our drm_plane. When merging 2 hwpipes, there are a few
constraints that we need to keep in mind:

- Only the same types of SSPPs are preferred. I.e, a RGB pipe should
  be paired with another RGB pipe, VIG with VIG etc.
- The hwpipe staged on the left should have a higher priority than
  the hwpipe staged on the right. The priorities are as follows:
  VIG0 > VIG1 > VIG2 > VIG3
  RGB0 > RGB1 > RGB2 > RGB3
  DMA0 > DMA1

We can't apply these constraints easily if mdp5_pipe_assign() is
called twice. Update mdp5_pipe_assign() to find both hwpipes in
one go, and add the extra constraints needed.

Since we enabled runtime PM, we cannot count on cursor registers to
retain their values.  This can result in situations where we think the
cursor is enabled when we enable the CRTC but it is trying to scan out
null (and the rest of cursor position/size is lost), resulting in faults
and generally angering the hw when coming out of DPMS with a cursor
enabled.

4c7085a5d5 drm/msm: Shadow current pointer in the ring until command is complete
Add a shadow pointer to track the current command being written into
the ring. Don't commit it as 'cur' until the command is submitted.
Because 'cur' is used to construct the software copy of the wptr this
ensures that somebody peeking in on the ring doesn't assume that a
command is inflight while it is being written. This isn't a huge deal
with a single ring (though technically the hangcheck could assume
the system is prematurely busy when it isn't) but it will be rather
important for preemption where the decision to preempt is based
on a non-empty ringbuffer. Without a shadow an aggressive preemption
scheme could assume that the ringbuffer is non empty and switch to it
before the CPU is done writing the command and boom.

Even though preemption won't be supported for all targets because of
the way the code is organized it is simpler to make this generic for
all targets. The extra load for non-preemption targets should be
minimal.

f97decac5f drm/msm: Support multiple ringbuffers
Add the infrastructure to support the idea of multiple ringbuffers.
Assign each ringbuffer an id and use that as an index for the various
ring specific operations.

The biggest delta is to support legacy fences. Each fence gets its own
sequence number but the legacy functions expect to use a unique integer.
To handle this we return a unique identifier for each submission but
map it to a specific ring/sequence under the covers. Newer users use
a dma_fence pointer anyway so they don't care about the actual sequence
ID or ring.

The actual mechanics for multiple ringbuffers are very target specific
so this code just allows for the possibility but still only defines
one ringbuffer for each target family.

f7de15450e drm/msm: Add per-instance submit queues
Currently the behavior of a command stream is provided by the user
application during submission and the application is expected to internally
maintain the settings for each 'context' or 'rendering queue' and specify
the correct ones.

This works okay for simple cases but as applications become more
complex we will want to set context specific flags and do various
permission checks to allow certain contexts to enable additional
privileges.

Add kernel-side submit queues to be analogous to 'contexts' or
'rendering queues' on the application side. Each file descriptor
instance will maintain its own list of queues. Queues cannot be
shared between file descriptors.

For backwards compatibility context id '0' is defined as a default
context specifying no priority and no special flags. This is
intended to be the usual configuration for 99% of applications so
that a garden variety application can function correctly without
creating a queue. Only those applications requiring the specific
benefit of different queues need create one.

Instead move request_firmware() to gpu->hw_init() and construct the gpu

yet, stash the gpu ptr in the adreno device's drvdata, and don't set

When an event with pending waiters is destroyed, those waiters may
end up sleeping forever unless they are notified and woken up.
Implement the notification by clearing the waiter->event pointer,
which becomes invalid anyway, when the event is freed, and waking
up the waiting tasks.

Waiters on an event that's destroyed return failure.

fdf0c8332a drm/amdkfd: Clean up kfd_wait_on_events
Cleaned up the code while resolving some potential bugs and
inconsistencies in the process.

Clean-ups:
* Remove enum kfd_event_wait_result, which duplicates
  KFD_IOC_EVENT_RESULT definitions
* alloc_event_waiters can be called without holding p->event_mutex
* Return an error code from copy_signaled_event_data instead of bool
* Clean up error handling code paths to minimize duplication in
  kfd_wait_on_events

Fixes:
* Consistently return an error code from kfd_wait_on_events and set
  wait_result to KFD_IOC_WAIT_RESULT_FAIL in all failure cases.
* Always call free_waiters while holding p->event_mutex
* copy_signaled_event_data might sleep. Don't call it while the task state
  is TASK_INTERRUPTIBLE.

9b56bb1154 drm/amdkfd: Don't dereference kfd_process.mm
The kfd_process doesn't own a reference to the mm_struct, so it can
disappear without warning even while the kfd_process still exists.

Therefore, avoid dereferencing the kfd_process.mm pointer and make
it opaque. Use get_task_mm to get a temporary reference to the mm
when it's needed.

894e287b3d drm/i915/gvt: Adding ACTHD mmio read handler
When a workload is too heavy to finish it in gpu hang check timer
intervals(1.5), gpu hang check function will check ACTHD register
value to decide whether gpu is real dead or not. On real hw,
ACTHD is updated by HW when workload is running, then host kernel
won't think it is gpu hang. while guest kernel always read a constant
ACTHD value as GVT doesn't supply ACTHD emulate handler, then
guest kernel detects a fake gpu hang.

To remove such guest fake gpu hang, this patch supply ACTHD
mmio read handler which read real HW ACTHD register directly.

6aa7de0591 locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to READ_ONCE()/WRITE_ONCE()
Please do not apply this to mainline directly, instead please re-run the
coccinelle script shown below and apply its output.

For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
preference to ACCESS_ONCE(), and new code is expected to use one of the
former. So far, there's been no reason to change most existing uses of

However, for some features, the read/write distinction is critical to

62884cd386 drm: Add four ioctls for managing drm mode object leases [v7]
drm_mode_create_lease

	Creates a lease for a list of drm mode objects, returning an
	fd for the new drm_master and a 64-bit identifier for the lessee

drm_mode_list_lesees

	List the identifiers of the lessees for a master file

drm_mode_get_lease

	List the leased objects for a master file

drm_mode_revoke_lease

	Erase the set of objects managed by a lease.

This should suffice to at least create and query leases.

Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>:

 * query ioctls only query the master associated with
   the provided file.

 * 'mask_lease' value has been removed

 * change ioctl has been removed.

Changes for v3 suggested in part by Dave Airlie <airlied@gmail.com>

 * Add revoke ioctl.

Changes for v4 suggested by Dave Airlie <airlied@gmail.com>

 * Expand on the comment about the magic use of &drm_lease_idr_object
 * Pad lease ioctl structures to align on 64-bit boundaries

Changes for v5 suggested by Dave Airlie <airlied@gmail.com>

 * Check for non-negative object_id in create_lease to avoid debug
   output from the kernel.

Changes for v6 provided by Dave Airlie <airlied@gmail.com>

 * For non-universal planes add primary/cursor planes to lease

   If we aren't exposing universal planes to this userspace client,
   and it requests a lease on a crtc, we should implicitly export the
   primary and cursor planes for the crtc.

   If the lessee doesn't request universal planes, it will just see
   the crtc, but if it does request them it will then see the plane
   objects as well.

   This also moves the object look ups earlier as a side effect, so
   we'd exit the ioctl quicker for non-existant objects.

 * Restrict leases to crtc/connector/planes.

   This only allows leasing for objects we wish to allow.

Changes for v7 provided by Dave Airlie <airlied@gmail.com>

 * Check pad args are 0
 * Check create flags and object count are valid.
 * Check return from fd allocation
 * Refactor lease idr setup and add some simple validation
 * Use idr_mutex uniformly (Keith)

7de440db20 drm: Check mode object lease status in all master ioctl paths [v4]
Attempts to modify un-leased objects are rejected with an error.
Information returned about unleased objects is modified to make them
appear unusable and/or disconnected.

Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>:

 * With the change in the __drm_mode_object_find API to pass the
   file_priv along, we can now centralize most of the lease-based
   access checks in that function.

 * A few places skip that API and require in-line checks.

Changes for v3 provided by Dave Airlie <airlied@redhat.com>

 * remove support for leasing encoders.
 * add support for leasing planes.

Changes for v4

 * Only call drm_lease_held if DRIVER_MODESET.

2ed077e467 drm: Add drm_object lease infrastructure [v5]
This provides new data structures to hold "lease" information about
drm mode setting objects, and provides for creating new drm_masters
which have access to a subset of the available drm resources.

An 'owner' is a drm_master which is not leasing the objects from
another drm_master, and hence 'owns' them.

A 'lessee' is a drm_master which is leasing objects from some other
drm_master. Each lessee holds the set of objects which it is leasing
from the lessor.

A 'lessor' is a drm_master which is leasing objects to another
drm_master. This is the same as the owner in the current code.

The set of objects any drm_master 'controls' is limited to the set of
objects it leases (for lessees) or all objects (for owners).

Objects not controlled by a drm_master cannot be modified through the
various state manipulating ioctls, and any state reported back to user
space will be edited to make them appear idle and/or unusable. For
instance, connectors always report 'disconnected', while encoders
report no possible crtcs or clones.

The full list of lessees leasing objects from an owner (either
directly, or indirectly through another lessee), can be searched from
an idr in the drm_master of the owner.

Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>:

* Sub-leasing has been disabled.

* BUG_ON for lock checking replaced with lockdep_assert_held

* 'change' ioctl has been removed.

* Leased objects can always be controlled by the lessor; the
  'mask_lease' flag has been removed

* Checking for leased status has been simplified, replacing
  the drm_lease_check function with drm_lease_held.

Changes in v3, some suggested by Dave Airlie <airlied@gmail.com>

* Add revocation. This allows leases to be effectively revoked by
  removing all of the objects they have access to. The lease itself
  hangs around as it's hanging off a file.

* Free the leases IDR when the master is destroyed

* _drm_lease_held should look at lessees, not lessor

* Allow non-master files to check for lease status

Changes in v4, suggested by Dave Airlie <airlied@gmail.com>

* Formatting and whitespace changes

Changes in v5 (airlied)

* check DRIVER_MODESET before lease destroy call
* check DRIVER_MODESET for lease revoke (Chris)
* Use idr_mutex uniformly for all lease elements of struct drm_master. (Keith)

This contains a bit of cleanup and some minor fixes for the host1x and
 Tegra DRM drivers. There's also some more preparatory work for Tegra186
 support which I'm not quite ready to send upstream because the GPIO
 driver needed for HDMI support has been stuck for months, and we can't
 do much without it. Hopefully that driver will land in v4.15, which
 would mean we could go ahead with Tegra186 display support in v4.16.

62676d10b4 qxl: alloc & use shadow for dumb buffers
This patch changes the way the primary surface is used for dumb
framebuffers.  Instead of configuring the bo itself as primary surface
a shadow bo is created and used instead.  Framebuffers can share the
shadow bo in case they have the same format and resolution.

On atomic plane updates we don't have to update the primary surface in
case we pageflip from one framebuffer to another framebuffer which
shares the same shadow.  This in turn avoids the flicker caused by the
primary-destroy + primary-create cycle, which is very annonying when
running wayland on qxl.

The qxl driver never actually writes to the shadow bo.  It sends qxl
blit commands which update it though, and the spice server might
actually execute them (and thereby write to the shadow) in case the
local rendering is kicked for some reason.  This happens for example in
case qemu is asked to write out a dump of the guest display (screendump
monitor command).

3064abfa93 drm: Add CRTC_GET_SEQUENCE and CRTC_QUEUE_SEQUENCE ioctls [v3]
These provide crtc-id based functions instead of pipe-number, while
also offering higher resolution time (ns) and wider frame count (64)
as required by the Vulkan API.

v2:

 * Check for DRIVER_MODESET in new crtc-based vblank ioctls

	Failing to check this will oops the driver.

 * Ensure vblank interupt is running in crtc_get_sequence ioctl

	The sequence and timing values are not correct while the
	interrupt is off, so make sure it's running before asking for
	them.

 * Short-circuit get_sequence if the counter is enabled and accurate

	Steal the idea from the code in wait_vblank to avoid the
	expense of drm_vblank_get/put

 * Return active state of crtc in crtc_get_sequence ioctl

	Might be useful for applications that aren't in charge of
	modesetting?

 * Use drm_crtc_vblank_get/put in new crtc-based vblank sequence ioctls

	Daniel Vetter prefers these over the old drm_vblank_put/get
	APIs.

 * Return s64 ns instead of u64 in new sequence event

Suggested-by: Daniel Vetter <daniel@ffwll.ch>
Suggested-by: Ville Syrjälä <ville.syrjala@linux.intel.com>

v3:

 * Removed FIRST_PIXEL_OUT_FLAG
 * Document that the timestamp in the query and event are
   that of the first pixel leaving the display engine for
   the display (using the same wording as the Vulkan spec).

fc9e9920b1 drm/amd/display: add hardware_planes_only to list of affected planes
For SoC's having software designed cursor plane,
should be treated differently than hardware cursor planes.

The DRM core initializes cursor plane by default with
legacy_cursor_update set.

Hence legacy_cursor_update can be use effectively
to handle software cursor planes' update and atomicity
functionalities.

This patch uses this variable to decide in the atomic_check
to whether add a requested plane to the list of affected planes or
not, hence fixing the issue of co-existence of MPO, i.e,
setting of available hardware planes like underlay and
updation of cursor planes as well.

Without this patch when underlay is set from user space,
only blank screen with backlight is visible.

abb4986eea drm/amd/display: Fix up plane_states add/remove logic
Our plane_states array trimming logic was faulty, we should be starting
to shuffle from the plane that was just released, not from the very
beginning of the array.

Also get rid of a leftover line that was setting the plane state at the
stream index to null, leading to issues. Also move the
dc_plane_state_retain call to where we reference plane_state, in case we
do hit the error case where we can't get a free pipe.

remnant fields in the dce110_link_enc_registers struct made it so that
the code still compiled, but any attempts to access the
LVTMA_PWRSEQ_STATE register led to reading from an address of 0. This
patch corrects that.

Also, rename blacklight_control to edp_backlight_control (Typo fix).

During system suspend, we:

1. Cache a duplicate of the current DRM atomic state, which calls hooks
   to duplicate our internal states.
2. Call hooks to disable all functionalities.
3. System suspended.

During resume, we attempt to restore the cached state. However, our
interal states are now stale, since step 1 was done before step 2.
i.e. our cached state does not reflect the disabled nature of things.

This change resolves that by destroying all relevant states to reflect
the actual state during resume.

According to VBT

+----------+-----------+--------------------+
| DDI Type | VBT Value | Bspec Mapped Value |

v2: Move defines to a better place.
    This is actually CNL_PCH not CNL only.
v3: Accepting Ville's suggestions: enums and array to

v4: Protect the array access as Ville suggested.
    Also accepting all Jani's suggestions:
    	      - use already defined gmbus pin definitions.
	      - use map_ddc_pin for disambiguation.
	      - Add /* sic */ comment on inverted values

bd386e5180 drm: Reorganize drm_pending_event to support future event types [v2]
Place drm_event_vblank in a new union that includes that and a bare
drm_event structure. This will allow new members of that union to be
added in the future without changing code related to the existing vbl
event type.

Assignments to the crtc_id field are now done when the event is
allocated, rather than when delievered. This way, delivery doesn't
need to have the crtc ID available.

v2:
 * Remove 'dev' argument from create_vblank_event

	It wasn't being used anyways, and if we need it in the future,
	we can always get it from crtc->dev.

 * Check for MODESETTING before looking for crtc in queue_vblank_event

	UMS drivers will oops if we try to get a crtc, so make sure
	we're modesetting before we try to find a crtc_id to fill into
	the event.

570e86963a drm: Widen vblank count to 64-bits [v3]
This modifies the datatypes used by the vblank code to provide 64 bits
of vblank count.

The driver interfaces have been left using 32 bits of vblank count;
all of the code necessary to widen that value for the user API was
already included to handle devices returning fewer than 32-bits.

This will provide the necessary datatypes for the Vulkan API.

v2:

 * Re-write wait_vblank ioctl to ABSOLUTE sequence

    When an application uses the WAIT_VBLANK ioctl with RELATIVE

    within the kernel. We need to write that target back to the
    ioctl buffer and update the flags bits so that if the wait is
    interrupted by a signal, when it is re-started, it will target
    precisely the same vblank count as before.

 * Leave driver API with 32-bit vblank count

 * Rebase on top of Arnd Bergmann's patch which had
   the switch to ktime_t parts.

[airlied: fix conflict with Ville vblank change].

fb83be8873 drm/tegra: hdmi: Add cec-notifier support
In order to support CEC the HDMI driver has to inform the CEC driver
whenever the physical address changes. So when the EDID is read the
CEC driver has to be informed and whenever the hotplug detect goes
away.

This is done through the cec-notifier framework.

The link between the HDMI driver and the CEC driver is done through
the hdmi-phandle property in the tegra-cec node in the device tree.

af0c8c1056 drm/vc4: Fix sleeps during the IRQ handler for DSI transactions.
VC4's DSI1 has a bug where the AXI connection is broken for 32-bit
writes from the CPU, so we use the DMA engine to DMA 32-bit values
into registers instead.  That sleeps, so we can't do it from the top
half.

As a solution, use an interrupt thread so that all our writes happen
when sleeping is is allowed.

v2: Use IRQF_ONESHOT (suggested by Boris)
v3: Style nitpicks.

e71de07661 drm/amdgpu: report more amdgpu_fence_info
Only for GFX ring. This can help checking MCBP feature.

The fence at the end of the frame will indicate the completion status.
If the frame completed normally, the fence is written to the address
given in the EVENT_WRITE_EOP packet. If preemption occurred in the
previous IB the address is adjusted by 2 DWs. If work submitted in the
frame was reset before completion, the fence address is adjusted by
four DWs. In the case that preemption occurred, and before preemption
completed a reset was initiated, the address will be adjusted with six
DWs

with current WB usage we only use 57 slots, so 512
is extreamly sufficient, and reduce to 512 can
