25fed6b324 Merge tag 'drm-intel-gt-next-2021-08-06-1' of ssh://git.freedesktop.org/git/drm/drm-intel into drm-next
UAPI Changes:

- Add I915_MMAP_OFFSET_FIXED

  On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid
  type. On devices without local memory, this caching mode is invalid.

  As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will
  be used, depending on the object placement on creation. WB will be used
  when the object can only exist in system memory, WC otherwise.

  Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888

- Reinstate the mmap ioctl for (already released) integrated Gen12 platforms

  Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is
  still to sunset the IOCTL even for integrated and require using mmap_offset.

- Reject caching/set_domain IOCTLs on discrete

  Expected to become immutable property of the BO

- Disallow changing context parameters after first use on Gen12 and earlier
- Require setting context parameters at creation on platforms after Gen12

  Rationale (for both): Allow less dynamic changes to the context to simplify
  the implementation and avoid user shooting theirselves in the foot.

- Drop I915_CONTEXT_PARAM_RINGSIZE

  Userspace PR for compute-driver has not been merged

- Drop I915_CONTEXT_PARAM_NO_ZEROMAP

  Userspace PR for libdrm / Beignet was never landed

- Drop CONTEXT_CLONE API

  Userspace PR for Mesa was never landed

- Drop getparam support for I915_CONTEXT_PARAM_ENGINES

  Only existed for symmetry wrt. setparam, never used.

- Disallow bonding of virtual engines

  Drop the prep work, no hardware has been released needing it.

- (Implicit) Disable gpu relocations

  Media userspace was the last userspace to still use them. They
  have converted so performance can be regained with an update.

dbac4f3946 drm/i915: remove explicit CNL handling from intel_pm.c
Remove support for CNL as it's highly untested, probably broken, and
there is no real platform that requires this code. This is part of CNL

49f756342b drm/i915/dg2: Add dbuf programming
DG2 extends our DDB to four DBuf slices; pipes A+B only have access to
the first two slices, whereas pipes C+D only have access to the second
two.

Confusingly, our bspec decided to switch from 1-based numbering
of dbuf slices (S1, S2) to 0-based numbering (S0, S1, S2, S3) in
Display13.  At the moment we're using the 0-based number scheme for the
DBUF_CTL_S() register addressing, but the 1-based number scheme in the
actual slice assignment tables.  We may want to consider switching the
assignment over to 0-based numbering too at some point...

46b0d7091c drm/i915: Make display workaround upper bounds exclusive
Workarounds are documented in the bspec with an exclusive upper bound
(i.e., a "fixed" stepping that no longer needs the workaround).  This
makes our driver's use of an inclusive upper bound for stepping ranges
confusing; the differing notation between code and bspec makes it very
easy for mistakes to creep in.

Let's switch the upper bound of our IS_{GT,DISP}_STEP macros over to use
an exclusive upper bound like the bspec does.  This also has the benefit
of helping make sure workarounds are properly handled for new minor
steppings that show up (e.g., an A1 between the A0 and B0 we already
knew about) --- if the new intermediate stepping pulls in hardware fixes
early, there will be an update to the workaround definition which lets
us know we need to change our code.  If the new stepping does not pull a
hardware fix earlier, then the new stepping will already be captured
properly by the "[begin, fix)" range in the code.

We'll probably need to be extra vigilant in code review of new
workarounds for the near future to make sure developers notice the new
semantics of workaround bounds.  But we just migrated a bunch of our
platforms from the IS_REVID bounds over to IS_{GT,DISP}_STEP, so people
are already adjusting to the new macros and now is a good time to make
this change too.

1e1824de33 drm/i915: Program DFR enable/disable as a GT workaround
DFR programming (which we enable as an optimization on gen11, but must
ensure is disabled on gen12) should be handled as a GT workaround rather
than clock gating initialization.  This will ensure that the programming

0d6695b112 drm/i915/adl_p: Same slices mask is not same Dbuf state
We currently treat same slice mask as a same DBuf state and skip
updating the Dbuf slices, if we detect that.
This is wrong as if we have a multi to single pipe change or
vice versa, that would be treated as a same Dbuf state and thus
no changes required, so we don't get Mbus updated, causing issues.
Solution: check also mbus_join, in addition to slices mask.

The actual dbuf programming will use offsets relative to the

offsets into the dbuf_state->ddb[] and crtc_state->plane_ddb*[].

For crtc_state->wm.skl.ddb however we want to stick to global
offsets as we use this to sanity check that the ddb allocations
don't overlap between pipes.

XE_LPD reduces the number of regular watermark latency levels from 8
to 6 on non-dgfx platforms.  However the hardware also adds a special
purpose SAGV wateramrk (and an accompanying transition watermark) that
will be used by the hardware in place of the level 0 values during SAGV
transitions.

1003cee29f drm/i915/xelpd: Increase maximum watermark lines to 255
XE_LPD continues to use the same "skylake-style" watermark
programming as other recent platforms.  The only change to the watermark
calculations compared to Display12 is that XE_LPD now allows a
maximum of 255 lines vs the old limit of 31.

Due to the larger possible lines value, the corresponding bits
representing the value in PLANE_WM are also extended, so make sure we
read/write enough bits.  Let's also take this opportunity to switch over
to the REG_FIELD notation.

e7c6e405e1 Fix misc new gcc warnings
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably
"-Wstringop-overread" and "-Warray-parameter".

Both of them cause what seem to be valid warnings in the kernel, where
we have array size mismatches in function arguments (that are no longer
just silently converted to a pointer to element, but actually checked).

This fixes most of the trivial ones, by making the function declaration
match the function definition, and in the case of intel_pm.c, removing
the over-specified array size from the argument declaration.

At least one 'stringop-overread' warning remains in the i915 driver, but
that one doesn't have the same obvious trivial fix, and may or may not
actually be indicative of a bug.

[ It was a mistake to upgrade one of my machines to Fedora 34 while
  being busy with the merge window, but if this is the extent of the
  compiler upgrade problems, things are better than usual    - Linus ]

93e7e61eb4 drm/i915/display: rename display version macros
While converting the rest of the driver to use GRAPHICS_VER() and
MEDIA_VER(), following what was done for display, some discussions went
back on what we did for display:

	1) Why is the == comparison special that deserves a separate
	macro instead of just getting the version and comparing directly
	like is done for >, >=, <=?

	2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for
	brevity. If we remove the current users of IS_DISPLAY_VER(), we
	could actually repurpose it for a range check

With (1) there could be an advantage if we used gen_mask since multiple
conditionals be combined by the compiler in a single and instruction and
check the result. However a) INTEL_GEN() doesn't use the mask since it
would make the code bigger everywhere else and b) in the cases it made
sense, it also made sense to convert to the _RANGE() variant.

So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range
like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER()
users to use == and != operators. Aside from the definition changes,
this was done by the following semantic patch:

	@@ expression dev_priv, E1; @@
	- !IS_DISPLAY_VER(dev_priv, E1)
	+ DISPLAY_VER(dev_priv) != E1

	@@ expression dev_priv, E1; @@
	- IS_DISPLAY_VER(dev_priv, E1)
	+ DISPLAY_VER(dev_priv) == E1

	@@ expression dev_priv, from, until; @@
	- IS_DISPLAY_RANGE(dev_priv, from, until)
	+ IS_DISPLAY_VER(dev_priv, from, until)

2446e1d643 drm/i915/display: Eliminate IS_GEN9_{BC,LP}
Now that we've eliminated INTEL_GEN(), IS_GEN_RANGE(), etc. from the
display code, we should also kill off our use of the IS_GEN9_* macros
too.  We'll do the conversion manually this time instead of using
Coccinelle since the most logical substitution can depend heavily on the
code context, and sometimes we can keep the code simpler if we make
additional adjustments such as swapping the order of if/else arms.

v2:
 - Restore a lost negation in intel_pll_is_valid().

bf52dc49ba drm/i915: Don't zero out the Y plane's watermarks
Don't zero out the watermarks for the Y plane since we've already
computed them when computing the UV plane's watermarks (since the
UV plane always appears before ethe Y plane when iterating through
the planes).

This leads to allocating no DDB for the Y plane since .min_ddb_alloc
also gets zeroed. And that of course leads to underruns when scanning
out planar formats.

2b5a4562ed drm/i915/display: Simplify GLK display version tests
GLK has always been a bit of a special case since it reports INTEL_GEN()
as 9, but has version 10 display IP.  Now we can properly represent the
display version as 10 and simplify the display generation tests
throughout the display code.

Aside from manually adding the version to the glk_info structure, the
rest of this patch is generated with a Coccinelle semantic patch.  Note
that we also need to switch any code that matches gen10 today but *not*
GLK to be CNL-specific:

7dadd28688 drm/i915: Convert INTEL_GEN() to DISPLAY_VER() as appropriate in intel_pm.c
Although most of the code in this file is display-related (watermarks),
there's some functions that are not (e.g., clock gating).  Thus we need
to do the conversions to DISPLAY_VER() manually here rather than using
Coccinelle.

In the near-future we'll probably want to think about moving watermark
logic out of intel_pm.c and into watermark-specific files under the
display/ directory.

v2:
 - Use new IS_DISPLAY_VER macro where appropriate.

8e62438a1e drm/i915: Workaround async flip + VT-d corruption on HSW/BDW
On HSW/BDW with VT-d active the first tile row scanned out
after the first async flip of the frame often ends up corrupted.

Whether the corruption happens or not depends on the scanline
on which the async flip happens, but the behaviour seems very
consistent. Ie. the same set of scanlines (which are most scanlines)
always show the corruption. And another set of scanlines (far less
of them) never shows the corruption.

I discovered that disabling the fetch-stride stretching
feature cures the corruption. This is some kind of TLB related
prefetch thing AFAIK. We already disable it on SNB primary
planes due to a documented workaround. The hardware folks
indicated that disabling this should be fine, so let's go
with that.

And while we're here, let's document the relevant bits on all
pre-skl platforms.
