KVM: SVM: Unwind "speculative" RIP advancement if INTn injection "fails"
Unwind the RIP advancement done by svm_queue_exception() when injecting
an INT3 ultimately "fails" due to the CPU encountering a VM-Exit while
vectoring the injected event, even if the exception reported by the CPU
isn't the same event that was injected. If vectoring INT3 encounters an
exception, e.g. #NP, and vectoring the #NP encounters an intercepted
exception, e.g. #PF when KVM is using shadow paging, then the #NP will
be reported as the event that was in-progress.
Note, this is still imperfect, as it will get a false positive if the
INT3 is cleanly injected, no VM-Exit occurs before the IRET from the INT3
handler in the guest, the instruction following the INT3 generates an
exception (directly or indirectly), _and_ vectoring that exception
encounters an exception that is intercepted by KVM. The false positives
could theoretically be solved by further analyzing the vectoring event,
e.g. by comparing the error code against the expected error code were an
exception to occur when vectoring the original injected exception, but
SVM without NRIPS is a complete disaster, trying to make it 100% correct
is a waste of time.

KVM: nSVM: Sync next_rip field from vmcb12 to vmcb02
The next_rip field of a VMCB is *not* an output-only field for a VMRUN.
This field value (instead of the saved guest RIP) in used by the CPU for
the return address pushed on stack when injecting a software interrupt or
INT3 or INTO exception.
Make sure this field gets synced from vmcb12 to vmcb02 when entering L2 or
loading a nested state and NRIPS is exposed to L1. If NRIPS is supported
in hardware but not exposed to L1 (nrips=0 or hidden by userspace), stuff
vmcb02's next_rip from the new L2 RIP to emulate a !NRIPS CPU (which
saves RIP on the stack as-is).

KVM: x86: do not report a vCPU as preempted outside instruction boundaries
If a vCPU is outside guest mode and is scheduled out, it might be in the
process of making a memory access. A problem occurs if another vCPU uses
the PV TLB flush feature during the period when the vCPU is scheduled
out, and a virtual address has already been translated but has not yet
been accessed, because this is equivalent to using a stale TLB entry.
To avoid this, only report a vCPU as preempted if sure that the guest
is at an instruction boundary. A rescheduling request will be delivered
to the host physical CPU as an external interrupt, so for simplicity
consider any vmexit *not* instruction boundary except for external
interrupts.
It would in principle be okay to report the vCPU as preempted also
if it is sleeping in kvm_vcpu_block(): a TLB flush IPI will incur the
vmentry/vmexit overhead unnecessarily, and optimistic spinning is
also unlikely to succeed. However, leave it for later because right
now kvm_vcpu_check_block() is doing memory accesses. Even
though the TLB flush issue only applies to virtual memory address,
it's very much preferrable to be conservative.

KVM: x86: do not set st->preempted when going back to user space
Similar to the Xen path, only change the vCPU's reported state if the vCPU
was actually preempted. The reason for KVM's behavior is that for example
optimistic spinning might not be a good idea if the guest is doing repeated
exits to userspace; however, it is confusing and unlikely to make a difference,
because well-tuned guests will hardly ever exit KVM_RUN in the first place.

drm/msm: Fix double pm_runtime_disable() call
Following commit 17e822f7591f ("drm/msm: fix unbalanced
pm_runtime_enable in adreno_gpu_{init, cleanup}"), any call to
adreno_unbind() will disable runtime PM twice, as indicated by the call
trees below:
Note that pm_runtime_force_suspend() is called right before
gpu->funcs->destroy() and both functions are called unconditionally.
With recent addition of the eDP AUX bus code, this problem manifests
itself when the eDP panel cannot be found yet and probing is deferred.
On the first probe attempt, we disable runtime PM twice as described
above. This then causes any later probe attempt to fail with
[drm:adreno_load_gpu [msm]] *ERROR* Couldn't power up the GPU: -13
preventing the driver from loading.
As there seem to be scenarios where the aNxx_destroy() functions are not
called from adreno_unbind(), simply removing pm_runtime_disable() from
inside adreno_unbind() does not seem to be the proper fix. This is what
commit 17e822f7591f ("drm/msm: fix unbalanced pm_runtime_enable in
adreno_gpu_{init, cleanup}") intended to fix. Therefore, instead check
whether runtime PM is still enabled, and only disable it in that case.

drm/amd/display: Add PSR-SU-RC support in DC
[Why]
PSR-SU Rate Control - or PSR-SU-RC - enables PSR-SU panels to work with
variable refresh rate to allow for more power savings. Lowering the
refresh rate can increase PSR residency by expanding the eDP main link
shut down duration. It can also lower panel power consumption.
There is a complication with PSR, since the eDP main link can be shut
down. Therefore, the timing controller (TCON) on the eDP sink nees to be
able to scan out its remote buffer independent of the main link. To
allow the eDP source to specify the sink's refresh rate while the link
is off, vendor-specific DPCD registers are used. This allows the eDP
source to then "Rate Control" the panel during PSR active.
[How]
Add DC support to communicate with PSR-SU-RC supported eDP sinks. The
sink will need to know the desired VTotal during PSR active.
This change only adds support to DC, support in amdgpu_dm is still
pending to enable this fully.

drm/amd/display: add DP sanity checks during enable stream
[why]
1. When HPD deassertion is pulled in the middle of
enabe stream link training, we will abort current training
and turn off PHY. This causes current link settings
to be zeroed this causes later stream enablement
sequence to fail as we prefer to carry on enablement
process despite of link training failure for SST.
2. When HPD is toggled after detection before before
the enable stream sequence as a result. There could be
a race condition where we could end up enable stream based
on the previous link even though the link is updated
after the HPD toggle. This causes an issue where our link
bandwidth is no longer enough to accommodate the timing
therefore causes us to oversubscribe MST payload time
slots. As discussed we decided to add basic sanity check
to make sure that our code can handle the oversubscription
failure silently without system hang.
[how]
1. Keep PHY powered on when HPD is deasserted during
enable stream and wait for the detection sequence to power
it off later.
2. Do not allocate payload if the required timeslot for
current timing is greater than 64 timeslots.

drm/amd/display: Correct min comp buffer size
[Why]
In 3-way mpo pipes, there is a case that we
overbook the CRB buffer size. At rare instances,
overbooking the crb will cause underflow. This only
happens when det_size changes dynamically
based on pipe_cnt.
[How]
Set min compbuff size to 1 segment when preparing BW.

drm/amd/display: Blank eDP on enable drv if odm enabled
[Why]
For panels with pixel clock > 1200MHz that require ODM
in pre-OS, when driver is disabled in OS, odm is enabled.
Upon driver enablement, corruption is seen if
odm was originally enabled. DP_PIXEL_COMBINE and
pixelclk must be programmed prior to programming the
optc-odm registers. However, eDP displays aren't blanked
prior to initializing odm in this case.
[How]
Upon driver enablement, check whether odm is enabled,
if so, blank eDP prior to programming optc-odm
registers.

drm/amd/display: Avoid reading LTTPR caps in non-LTTPR mode.
[Why]
LTTPR capable devices on the DisplayPort path may assume that
extended LTTPR AUX timeouts will be used after LTTPR capabilities
are read.
When DPTX operates in non-LTTPR mode, AUX timeouts are not
extended and this can result in AUX transactions timing out.
[How]
Use shared helper function to determine LTTPR mode and do not
read LTTPR capabilities in non-LTTPR mode.
