drm/i915/selftests: Drop vestigal timeslicing assert
Since the semaphore interrupt may cause us to yield the timeslice

drm/i915/gt: Yield the timeslice if caught waiting on a user semaphore
If we find ourselves waiting on a MI_SEMAPHORE_WAIT, either within the
user batch or in our own preamble, the engine raises a
GT_WAIT_ON_SEMAPHORE interrupt. We can unmask that interrupt and so
respond to a semaphore wait by yielding the timeslice, if we have
another context to yield to!
The only real complication is that the interrupt is only generated for
the start of the semaphore wait, and is asynchronous to our
process_csb() -- that is, we may not have registered the timeslice before
we see the interrupt. To ensure we don't miss a potential semaphore
blocking forward progress (e.g. selftests/live_timeslice_preempt) we mark
the interrupt and apply it to the next timeslice regardless of whether it
was active at the time.
v2: We use semaphores in preempt-to-busy, within the timeslicing
implementation itself! Ergo, when we do insert a preemption due to an
expired timeslice, the new context may start with the missed semaphore
flagged by the retired context and be yielded, ad infinitum. To avoid
this, read the context id at the time of the semaphore interrupt and
only yield if that context is still active.

drm/i915/gem: Wait until the context is finally retired before releasing engines
If we want to percolate information back from the HW, up through the GEM

barrier, i.e. by listening to the pulse after the notional unpin. So
wait until the intel_context is finally retired before releasing the

drm/i915/perf: Do not clear pollin for small user read buffers
It is wrong to block the user thread in the next poll when OA data is
already available which could not fit in the user buffer provided in
the previous read. In several cases the exact user buffer size is not
known. Blocking user space in poll can lead to data loss when the
buffer size used is smaller than the available data.
This change fixes this issue and allows user space to read all OA data
even when using a buffer size smaller than the available data using
multiple non-blocking reads rather than staying blocked in poll till
the next timer interrupt.

drm/i915: Implement port sync for SKL+
Transcoder port sync was introduced to the hardware in BDW. We
can trivially enable it for SKL+ since the same codepaths are
already used for ICL+ port sync. The only difference is the actual
location of the bits we need to poke.
We leave BDW out (at least for now) since it uses different modeset
paths that haven't been adapted for port sync, and IIRC using the
feature would involve some extra workarounds we've not implemented.
Pre-BDW hardware does not support port sync so we'd have to tweak
the modeset sequence to start the pipes as close together as possible
and hope for the best. So far no one has seriously tried to implement
that.

drm/i915: Keep a per-engine request pool
Add a tiny per-engine request mempool so that we should always have a
request available for powermanagement allocations from tricky
contexts. This reserve is expected to be only used for kernel
contexts when barriers must be emitted [almost] without fail.
The main consumer for this reserved request is expected to be engine-pm,
for which we know that there will always be at least the previous pm
request that we can reuse under mempressure (so there should always be
a spare request for engine_park()).
This is an alternative to using a comparatively bulky mempool, which
requires custom handling for both our reserved allocation requirement
and to protect our TYPESAFE_BY_RCU slab cache. The advantage of mempool
would be that it would allow us to keep a larger per-engine request
pool. However, converting over to mempool is straightforward should the
need arise.

drm/i915/dp: Return the right vswing tables
DDI ports have its encoders initialized with INTEL_OUTPUT_DDI type and
later eDP ports that have the type changed to INTEL_OUTPUT_EDP.
But for all other DDI ports it can drive HDMI or DP depending on what
user connects to the ports.
ehl_get_combo_buf_trans() and tgl_get_combo_buf_trans() was checking
for INTEL_OUTPUT_DP that was never true, causing wrong vswing tables
being used.
So here replacing the INTEL_OUTPUT_DP checks by the valid output types
that this functions receives as parameters. HDMI cases will be
correctly handled as it do not use encoder->type, instead it calls the
functions with INTEL_OUTPUT_HDMI as type parameter and HDMI don't have
retraining.
v2:
changed INTEL_OUTPUT_DDI to INTEL_OUTPUT_EDP and INTEL_OUTPUT_HDMI

In this sequence, we can see that although we have submitted the next
request [ff84:45156] to HW (via ELSP[]) it has not yet reported the
lite-restore. Instead, we see the completion event of the currently
active request [ff84:45155] but at the time of processing that event,
the breadcrumb has not yet been written. Though by the time we do print
out the debug info, the seqno write of ff84:45156 has landed!
Therefore there is a serialisation problem between the seqno writes and
CS events, not just between the CS buffer and its head/tail pointers as
previously observed on Icelake.
This is not a huge problem, as we don't strictly rely on the breadcrumb
to determine HW activity, but it may indicate that interrupt delivery is
before the seqno write, aka bringing back the plague of missed
interrupts from yesteryear. However, there is no indication of this
wider problem, so let's just flush the seqno read before reporting an
error. If it persists after the fresh read we can worry again.

context (which is no longer idle).
We can achieve this by preventing the context from completing while we
reload a new ELSP (by applying ring_set_paused(1) across the whole of
dequeue), except this eventually fails due to a lite-restore into a
waiting semaphore does not generate an ACK. Instead, we try to avoid
making the GPU do anything too challenging and not submit a new ELSP

drm/i915/perf: rework aging tail workaround
We're about to introduce an options to open the perf stream, giving
the user ability to configure how often it wants the kernel to poll
the OA registers for available data.
Right now the workaround against the OA tail pointer race condition
requires at least twice the internal kernel polling timer to make any
data available.
This changes introduce checks on the OA data written into the circular
buffer to make as much data as possible available on the first
iteration of the polling timer.
v2: Use OA_TAKEN macro without the gtt_offset (Lionel)
v3: (Umesh)
- Rebase
- Change report to report32 from below review
https://patchwork.freedesktop.org/patch/330704/?series=66697&rev=1
v4: (Ashutosh, Lionel)
- Fix checkpatch errors
- Fix aging_timestamp initialization
- Check for only one valid landed report
- Fix check for unlanded report
v5: (Ashutosh)
- Fix bug in accurately determining landed report.
- Optimize the check for landed reports by going as far as the
previously determined aged tail.

drm/i915: Cast remain to unsigned long in eb_relocate_vma
A recent commit in clang added -Wtautological-compare to -Wall, which is
enabled for i915 after -Wtautological-compare is disabled for the rest
of the kernel so we see the following warning on x86_64:
../drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c:1433:22: warning:
result of comparison of constant
576460752303423487 with expression of
type 'unsigned int' is always false
[-Wtautological-constant-out-of-range-compare]

~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~
../include/linux/compiler.h:78:42: note: expanded from macro 'unlikely'
# define unlikely(x) __builtin_expect(!!(x), 0)
^
1 warning generated.
It is not wrong in the case where ULONG_MAX > UINT_MAX but it does not
account for the case where this file is built for 32-bit x86, where
ULONG_MAX == UINT_MAX and this check is still relevant.
Cast remain to unsigned long, which keeps the generated code the same
(verified with clang-11 on x86_64 and GCC 9.2.0 on x86 and x86_64) and
the warning is silenced so we can catch more potential issues in the
future.

drm/i915/huc: make "support huc" reflect HW capabilities
We currently initialize HuC support based on GuC being enabled in
modparam; this means that huc_is_supported() can return false on HW that
does have a HuC when enable_guc=0. The rationale for this behavior is
that HuC requires GuC for authentication and therefore is not supported
by itself. However, we do not allow defining HuC fw wthout GuC fw and
selecting HuC in modparam implicitly selects GuC as well, so we can't
actually hit a scenario where HuC is selected alone. Therefore, we can
flip the support check to reflect the HW capabilities and fw
availability, which is more intuitive and will make it cleaner to log
HuC the difference between not supported in HW and not selected.
Removing the difference between GuC and HuC also allows us to simplify
the init_early, since we don't need to differentiate the support based
on the type of uC.
