This reverts commit 9e31c1fe45. Ever
since that commit, we've been having issues where a hang in one client
can propagate to another. In particular, a hang in an app can propagate
to the X server which causes the whole desktop to lock up.
Error propagation along fences sound like a good idea, but as your bug
shows, surprising consequences, since propagating errors across security
boundaries is not a good thing.
What we do have is track the hangs on the ctx, and report information to
userspace using RESET_STATS. That's how arb_robustness works. Also, if my
understanding is still correct, the EIO from execbuf is when your context
is banned (because not recoverable or too many hangs). And in all these
cases it's up to userspace to figure out what is all impacted and should
be reported to the application, that's not on the kernel to guess and
automatically propagate.
What's more, we're also building more features on top of ctx error
reporting with RESET_STATS ioctl: Encrypted buffers use the same, and the
userspace fence wait also relies on that mechanism. So it is the path
going forward for reporting gpu hangs and resets to userspace.
So all together that's why I think we should just bury this idea again as
not quite the direction we want to go to, hence why I think the revert is
the right option here.

This reverts 686c7c35ab ("drm/i915/gem: Asynchronous cmdparser"). The
justification for this commit in the git history was a vague comment
about getting it out from under the struct_mutex. While this may
improve perf for some workloads on Gen7 platforms where we rely on the
command parser for features such as indirect rendering, no numbers were
provided to prove such an improvement. It claims to closed two
gitlab/bugzilla issues but with no explanation whatsoever as to why or
what bug it's fixing.
Meanwhile, by moving command parsing off to an async callback, it leaves
us with a problem of what to do on error. When things were synchronous,
EXECBUFFER2 would fail with an error code if parsing failed. When
moving it to async, we needed another way to handle that error and the
solution employed was to set an error on the dma_fence and then trust
that said error gets propagated to the client eventually. Moving back
to synchronous will help us untangle the fence error propagation mess.
This also reverts most of 0edbb9ba1b ("drm/i915: Move cmd parser

paths for asynchronous parsing. Now that everything is synchronous, we
don't need it.

The switch from old old IS_FOO_REVID() macros to the new table-based
IS_FOO_{GT,DISP}_STEP() macros is needed on both drm-intel-next (for
display-based DMC matching) and drm-intel-gt-next (for workaround
guards). To avoid conflicts, we'll apply the patches to a topic branch
and merge it to both intel branches to ensure the transition to the
new macros is clean.

Switch ICL to use a revid->stepping table as we're trying to do on all
platforms going forward. While we're at it, let's include some
additional steppings that have popped up, even if we don't yet have any
workarounds tied to those steppings (we probably need to audit our
workaround list soon to see if any of the bounds have moved or if new
workarounds have appeared).
Note that the current bspec table is missing information about how to
map PCI revision ID to GT/display steppings; it only provides an SoC
stepping. The mapping to GT/display steppings (which aren't always the
same as the SoC stepping) used to be in the bspec, but was apparently
dropped during an update in Nov 2019; I've made my changes here based on
an older bspec snapshot that still had the necessary information. We've
requested that the missing information be restored.
I'm only including the production revids in the table here since we're
past the point at which we usually stop trying to support pre-production
hardware. An appropriate check is added to
intel_detect_preproduction_hw() to print an error and taint the kernel
just in case someone still tries to load the driver on old
pre-production hardware.
v2:
- Drop pre-production steppings and add error/taint at startup when
loading on pre-production hardware.

Switch BXT to use a revid->stepping table as we're trying to do on all
platforms going forward. Note that the REVID macros we had before
weren't being used anywhere in the code and weren't even correct; the
table values come from the bspec (and omits all the placeholder and
preproduction revisions).
Although nothing in the code is using the data from this table at the
moment, we expect some upcoming DMC patches to start utilizing it.

Switch SKL to use a revid->stepping table as we're trying to do on all
platforms going forward. Also drop the preproduction revisions and add
the newer steppings we hadn't already handled.
Note that SKL has a case where a newer revision ID corresponds to an
older GT/disp stepping (0x9 -> STEP_J0, 0xA -> STEP_I1). Also, the lack
of a revision ID 0x8 in the table is intentional and not an oversight.
We'll re-write the KBL-specific comment to make it clear that these kind
of quirks are expected.
v2:
- Since GT and display steppings are always identical on SKL use a
macro to set both values at once in a more readable manner. (Anusha)

Although we're converting our workarounds to use a revid->stepping
lookup table, the function that detects pre-production hardware should
continue to compare against PCI revision ID values directly. These are
listed in the bspec as integers, so it's easier to confirm their
correctness if we just use an integer literal rather than a symbolic
name anyway.

We skip filling out the pt with scratch entries if the va range covers
the entire pt, since we later have to fill it with the PTEs for the
object pages anyway. However this might leave open a small window where
the PTEs don't point to anything valid for the HW to consume.
When for example using 2M GTT pages this fill_px() showed up as being
quite significant in perf measurements, and ends up being completely
wasted since we ignore the pt and just use the pde directly.
Anyway, currently we have our PTE construction split between alloc and
insert, which is probably slightly iffy nowadays, since the alloc
doesn't actually allocate anything anymore, instead it just sets up the
page directories and points the PTEs at the scratch page. Later when we
do the insert step we re-program the PTEs again. Better might be to
squash the alloc and insert into a single step, then bringing back this
optimisation(along with some others) should be possible.

CTB writes are now in the path of command submission and should be
optimized for performance. Rather than reading CTB descriptor values
(e.g. head, tail) which could result in accesses across the PCIe bus,

absolutely necessary. Also store the current space in the each channel
locally.

Add non blocking CTB send function, intel_guc_send_nb. GuC submission
will send CTBs in the critical path and does not need to wait for these
CTBs to complete before moving on, hence the need for this new function.
The non-blocking CTB now must have a flow control mechanism to ensure
the buffer isn't overrun. A lazy spin wait is used as we believe the
flow control condition should be rare with a properly sized buffer.
The function, intel_guc_send_nb, is exported in this patch but unused.
Several patches later in the series make use of this function.

The conversion to ww mutexes failed to address the fence code which
already returns -EDEADLK when we run out of fences. Ww mutexes on
the other hand treat -EDEADLK as an internal errno value indicating
a need to restart the operation due to a deadlock. So now when the
fence code returns -EDEADLK the higher level code erroneously
restarts everything instead of returning the error to userspace
as is expected.
To remedy this let's switch the fence code to use a different errno
value for this. -ENOBUFS seems like a semi-reasonable unique choice.
Apart from igt the only user of this I could find is sna, and even
there all we do is dump the current fence registers from debugfs
into the X server log. So no user visible functionality is affected.
If we really cared about preserving this we could of course convert
back to -EDEADLK higher up, but doesn't seem like that's worth
the hassle here.
Not quite sure which commit specifically broke this, but I'll
just attribute it to the general gem ww mutex work.
