In VRR mode, keep track of the vblank count of the last
completed pageflip in amdgpu_crtc->last_flip_vblank, as
recorded in the pageflip completion handler after each
completed flip.
Use that count to prevent mmio programming a new pageflip
within the same vblank in which the last pageflip completed,
iow. to throttle pageflips to at most one flip per video
frame, while at the same time allowing to request a flip
not only before start of vblank, but also anywhere within
vblank.
The old logic did the same, and made sense for regular fixed
refresh rate flipping, but in vrr mode it prevents requesting
a flip anywhere inside the possibly huge vblank, thereby
reducing framerate in vrr mode instead of improving it, by
delaying a slightly delayed flip requests up to a maximum
vblank duration + 1 scanout duration. This would limit VRR
usefulness to only help applications with a very high GPU
demand, which can submit the flip request before start of
vblank, but then have to wait long for fences to complete.
With this method a flip can be both requested and - after
fences have completed - executed, ie. it doesn't matter if
the request (amdgpu_dm_do_flip()) gets delayed until deep
into the extended vblank due to cpu execution delays. This
also allows clients which want to regulate framerate within
the vrr range a much more fine-grained control of flip timing,
a feature that might be useful for video playback, and is
very useful for neuroscience/vision research applications.
In regular non-VRR mode, retain the old flip submission
behavior. This to keep flip scheduling for fullscreen X11/GLX
OpenGL clients intact, if they use the GLX_OML_sync_control
extensions glXSwapBufferMscOML(, ..., target_msc,...) function
with a specific target_msc target vblank count.
glXSwapBuffersMscOML() or DRI3/Present PresentPixmap() will
not flip at the proper target_msc for a non-zero target_msc
if VRR mode is active with this patch. They'd often flip one
frame too early. However, this limitation should not matter
much in VRR mode, as scheduling based on vblank counts is
pretty futile/unusable under variable refresh duration
anyway, so no real extra harm is done.
According to some testing already done with this patch by
Nicholas on top of my tests, IGT tests didn't report any
problems. If fixes stuttering and flickering when flipping
at rates below the minimum vrr refresh rate.

The RC/UC code path can go through a software loopback. In this code path
the receive side QP is manipulated.
If two threads are working on the QP receive side (i.e. post_send, and
modify_qp to an error state), QP information can be corrupted.
(post_send via loopback)
set r_sge
loop
update r_sge

update r_sge <---- r_sge is now incorrect

Some sky2 chips fire IRQ after S3, before the driver is fully resumed:
[ 686.804877] do_IRQ: 1.37 No irq handler for vector
This is likely a platform bug that device isn't fully quiesced during
S3. Use MSI-X, maskable MSI or INTx can prevent this issue from
happening.
Since MSI-X and maskable MSI are not supported by this device, fallback
to use INTx on affected platforms.

Once channels were successfully opened, update tx reporter health state to
healthy. This is needed for the following scenario:
- SQ has an un-recovered error reported to the devlink health, resulting tx
reporter state to be error.
- Current channels (including this SQ) are closed
- New channels are opened
After that flow, the original error was "solved", and tx reporter state
should be healthy. However, as it was resolved as a side effect, and not
via tx reporter recover method, driver needs to inform devlink health
about it.

then the auto-negotiated values aren't propagated to the port,
resulting in a broken link. See discussion in [0]. This patch adds

Every in-kernel use of this function defined it to KERNEL_DS (either as
an actual define, or as an inline function). It's an entirely
historical artifact, and long long long ago used to actually read the
segment selector valueof '%ds' on x86.
Which in the kernel is always KERNEL_DS.
Inspired by a patch from Jann Horn that just did this for a very small
subset of users (the ones in fs/), along with Al who suggested a script.
I then just took it to the logical extreme and removed all the remaining
gunk.
Roughly scripted with
git grep -l '(get_ds())' -- :^tools/ | xargs sed -i 's/(get_ds())/(KERNEL_DS)/'
git grep -lw 'get_ds' -- :^tools/ | xargs sed -i '/^#define get_ds()/d'
plus manual fixups to remove a few unusual usage patterns, the couple of
inline function cases and to fix up a comment that had become stale.
The 'get_ds()' function remains in an x86 kvm selftest, since in user
space it actually does something relevant.

The write access of an implicit MR is inherited to all of its children.
Therefore we must set the correct write access to the parent MR.
Pass full access_flags when creating umem to let it calculate write access
correctly.

The ptr_to_compat() call takes a "void __user *", so cast
the compat drm calls that use it to avoid the following
warnings from sparse:

Kernel space provider driver should clean the CQs belonging to kernel
space consumers only. The current implementation is doing reverse of it.
Fixing the same by avoiding the call to __clean_cq on a kernel qp during
destroy.

Add PCIe Root Port support for Stratix 10 device.
Main differences compared to the PCIe Root Port IP on Cyclone V
and Arria 10 devices:
- HIP interface to access Root Port configuration register
- TLP programming flow:
- One REG0 register
- Don't need to check alignment

Currently the function pwm_imx27_get_state() of enables the clocks once
unconditionally at the start, a second time if the PWM is enabled and
disables unconditionally at the end.
Simplify that to enable once at the start and disable conditionally at
the end.

earth-pt1 driver was decomposed/restructured by the commit b732539efdba
("media: dvb: earth-pt1: decompose pt1 driver into sub drivers"),
but it introduced a problem regarding concurrent streaming:
Opening a new terrestial stream stops the reception of an existing,
already-opened satellite stream.
The demod IC in earth-pt1 boards contains 2 pairs of terr. and sat. blocks,
supporting 4 concurrent demodulations, and the above problem was because
the config of a terr. block contained whole reset/init of the pair blocks,
thus each open() of a terrestrial frontend wrongly cleared the config of
its peer satellite block of the demod.
This whole/pair reset should be executed earlier and not on each open().

The rcar_pwm_get_clock_division() has a loop to calculate the divider,
but the value of div should be calculatable without a loop. So, this
patch improves it.
