drm/i915/mtl: Add engine TLB invalidation
MTL's primary GT can continue to use the same engine TLB invalidation
programming as past Xe_HP-based platforms. However the media GT needs
some special handling:
* Invalidation registers on the media GT are singleton registers
(unlike the primary GT where they are still MCR).
* Since the GSC is now exposed as an engine, there's a new register to
use for TLB invalidation. The offset is identical to the compute
engine offset, but this is expected --- compute engines only exist on
the primary GT while the GSC only exists on the media GT.
* Although there's only a single GSC engine instance, it inexplicably
uses bit 1 to request invalidations rather than bit 0.
v2:
- Add a 'regs == xelpmp_regs' condition to the GSC instance handling.
If the registers change on a future platform, the GSC-specific
handling is likely to change as well. (Andrzej)

Although registers in the L3 bank/node configuration ranges are marked
as having "DEV" reset characteristics in the bspec, this appears to be a
hold-over from pre-Xe_HP platforms. In reality, these registers
maintain their values across engine resets, meaning that workarounds
and tuning settings targeting them should be placed on the GT
workaround list rather than an engine workaround list.
Note that an extra clue here is that these registers moved from the
RENDER forcewake domain to the GT forcewake domain in Xe_HP; generally
RCS/CCS engine resets should not lead to the reset of a register that
lives outside the RENDER domain.
Re-applying these registers on engine resets wouldn't actually hurt
anything, but is unnecessary and just makes it more confusing to anyone

drm/i915: Allow error capture without a request
There was a report of error captures occurring without any hung
context being indicated despite the capture being initiated by a 'hung
context notification' from GuC. The problem was not reproducible.
However, it is possible to happen if the context in question has no
active requests. For example, if the hang was in the context switch
itself then the breadcrumb write would have occurred and the KMD would
see an idle context.
In the interests of attempting to provide as much information as
possible about a hang, it seems wise to include the engine info
regardless of whether a request was found or not. As opposed to just
prentending there was no hang at all.
So update the error capture code to always record engine information
if a context is given. Which means updating record_context() to take a
context instead of a request (which it only ever used to find the
context anyway). And split the request agnostic parts of
intel_engine_coredump_add_request() out into a seaprate function.

drm/i915: Fix request ref counting during error capture & debugfs dump
When GuC support was added to error capture, the reference counting
around the request object was broken. Fix it up.
The context based search manages the spinlocking around the search
internally. So it needs to grab the reference count internally as
well. The execlist only request based search relies on external
locking, so it needs an external reference count but within the
spinlock not outside it.
The only other caller of the context based search is the code for
dumping engine state to debugfs. That code wasn't previously getting
an explicit reference at all as it does everything while holding the
execlist specific spinlock. So, that needs updaing as well as that
spinlock doesn't help when using GuC submission. Rather than trying to
conditionally get/put depending on submission model, just change it to
always do the get/put.
v2: Explicitly document adding an extra blank line in some dense code
(Andy Shevchenko). Fix multiple potential null pointer derefs in case
of no request found (some spotted by Tvrtko, but there was more!).

drm/i915/mtl: Correct implementation of Wa_18018781329
Workaround Wa_18018781329 has applied to several recent Xe_HP-based
platforms. However there are some extra gotchas to implementing this
properly for MTL that we need to take into account:
* Due to the separation of media and render/compute into separate GTs,
this workaround needs to be implemented on each GT, not just the
primary GT. Since each class of register only exists on one of the
two GTs, we should program the appropriate registers on each GT.
* As with past Xe_HP platforms, the registers on the primary GT (Xe_LPG
IP) are multicast/replicated registers and should be handled with the
MCR-aware functions. However the registers on the media GT (Xe_LPM+
IP) are regular singleton registers and should _not_ use MCR
handling. We need to create separate register definitions for the
Xe_HP multicast form and the Xe_LPM+ singleton form and use each in
the appropriate place.
* Starting with MTL, workarounds documented by the hardware teams are
technically associated with IP versions/steppings rather than
top-level platforms. That means we should take care to check the
media IP version rather than the graphics IP version when deciding
whether the workaround is needed on the Xe_LPM+ media GT (in this
case the workaround applies to both IPs and the stepping bounds are
identical, but we should still write the code appropriately to set a
proper precedent for future workaround implementations).
* It's worth noting that the GSC register and the CCS register are
defined with the same MMIO offset (0xCF30). Since the CCS is only
relevant to the primary GT and the GSC is only relevant to the media
GT there isn't actually a clash here (the media GT automatically adds
the additional 0x380000 GSI offset). However there's currently a
glitch in the bspec where the CCS register doesn't show up at all and
the GSC register is listed as existing on both GTs. That's a known
documentation problem for several registers with shared GSC/CCS
offsets; rest assured that the CCS register really does still exist.

drm/i915/xehp: GAM registers don't need to be re-applied on engine resets
Register reset characteristics (i.e., whether the register maintains or
loses its value on engine reset) is an important factor that determines
which wa_list we want to add workarounds to. We recently found out that
the bspec documentation for the Xe_HP's "GAM" registers in the 0xC800 -
0xCFFF range was misleading; these registers do not actually lose their
value on engine resets as the documentation implied. This means there's
no need to re-apply workarounds touching these registers after a reset,
and the corresponding workarounds should be moved from the 'engine'
lists back to the 'gt' list.
v2:
- Don't add Wa_18018781329 to xehpsdv; the original condition didn't
include that platform. (Gustavo)
- Move the MTL code to the GT function as-is for now; we'll take care
of the additional fixes needed in a follow-up patch.

drm/i915: Move/adjust register definitions related to Wa_22011450934
The implementation of Wa_22011450934 introduced three new register
definitions in i915_reg.h that didn't get moved to the GT/engine
register headers when all the other registers moved; let's move them to
the appropriate headers and tidy up their definitions now for
consistency:
- STATE_ACK_DEBUG is moved to the engine register header and converted
to a parameterized definition; the workaround only needs the RCS
instance to be programmed, but there are instances on other engines
that could be used by other workarounds in the future.
- The two CULLBIT registers move to the GT register header. Since
they belong to MMIO ranges that became MCR starting with Xe_HP,
their definitions should be defined as MCR_REG() and use an Xe_HP
prefix to keep the register semantics clear.
Note that the MCR definition is just for consistency and to prevent
accidental misuse if other workarounds related to these registers show
up in the future. There's no functional change to today's driver since
the workaround that references these registers only accesses them via
MI_LRR engine instructions. Engine-initiated register accesses do not
utilize the same steering controls as CPU-initiated accesses; they
use a different steering control register (0x20CC) which is initialized
to a non-terminated DSS target by pre-OS firmware and never changed
thereafter (i915 does not touch it and userspace does not have
permission to change that register).

If PXP arb-session is being attempted on older hardware SKUs or
on hardware with older, unsupported, firmware versions, then don't
report the failure with a drm_error. Instead, look specifically for
the API-version error reply and drm_dbg that reply. In this case, the

drm/vkms: reintroduce prepare_fb and cleanup_fb functions
With commit
359c6649cd9a ("drm/gem: Implement shadow-plane {begin,

By performing the vunmap at the end of the current pageflip, invalid

drm: document better that drivers shouldn't use drm_minor directly
The documentation for struct drm_minor already states this, but that's
not always that easy to find.
Also due to historical reasons we still have the minor-centric
interfaces (like drm_debugfs_create_files), but since this is now
getting fixed we can put a few more pointers in place as to how this
should be done ideally. Note that debugfs isn't there yet for all
cases (debugfs files on kms objects like crtc/connector aren't
supported, neither debugfs files with full fops), so the debugfs side
of this is still rather aspirational and more for new users than
converting everything existing. todo.rst covers the additional work
needed already.
Motivated by some discussion with Rodrigo on irc about how drm/xe
should lay out its sysfs interfaces.
v2: Make the debugfs situation clearer in the commit message, but
don't elaborate more in the actual kerneldoc to avoid distracting from
the main message around sysfs (Jani)
Also fix some typos.

drm/panel-asus-z00t-tm5p5-n35596: Drop custom DSI write macros
There are macros for these already in the <drm/drm_mipi_dsi.h> header, use
that instead and delete the custom DSI write macros defined in the driver.

drm/i915/guc: Replace zero-length arrays with flexible-array members
Zero-length arrays are deprecated[1] and we are moving towards
adopting C99 flexible-array members, instead. So, replace zero-length
arrays in a couple of structures (three, actually) with flex-array
members.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [2].

drm/i915: Do not cover all future platforms in TLB invalidation
Revert to the original explicit approach and document the reasoning
behind it.
v2:
* DG2 needs to be covered too. (Matt)
v3:
* Full version check for Gen12 to avoid catching all future platforms.
(Matt)
v4:
* Be totally explicit on the Gen12 branch. (Andrzej)

drm/amd/display: No need for Null pointer check before kfree
kfree() & vfree() internally performs NULL check on the pointer handed
to it and take no action if it indeed is NULL. Hence there is no need
for a pre-check of the memory pointer before handing it to
kfree()/vfree().
