1eb3133899 drm/i915/pvc: Remove additional 3D flags from PIPE_CONTROL
Although we already strip 3D-specific flags from PIPE_CONTROL
instructions when submitting to a compute engine, there are some
additional flags that need to be removed when the platform as a whole
lacks a 3D pipeline.  Add those restrictions here.

v2:
 - Replace LACKS_3D_PIPELINE checks with !HAS_3D_PIPELINE and add
   has_3d_pipeline to all platforms except PVC.  (Lucas)

d32e8ed918 drm/i915/uncore: Reorganize and document shadow and forcewake tables
Let's reorganize some of the forcewake/shadow handling in intel_uncore.c
and consolidate the cargo-cult comments on each table into more general
comments that apply to all tables.

We'll probably move forcewake handling to its own dedicated file in the
near future and further enhance this with true kerneldoc.  But this is a
good intermediate step to help clarify the behavior a bit.

421cfe6596 vfio: remove VFIO_GROUP_NOTIFY_SET_KVM
Rather than relying on a notifier for associating the KVM with
the group, let's assume that the association has already been
made prior to device_open.  The first time a device is opened
associate the group KVM with the device.

This fixes a user-triggerable oops in GVT.

991dcb89ca drm/i915/d12+: Disable DMC firmware flip queue handlers
Based on a bspec update the DMC firmware's flip queue handling events
need to be disabled before enabling DC5/6. i915 doesn't use the flip
queue feature atm, so disable it already after loading the firmware.
This removes some overhead of the event handler which runs at a 1 kHz
frequency.

Bspec: 49193, 72486, 72487

v2:
- Fix the DMC pipe A register offsets for GEN12.
- Disable the events on DG2 only on pipe A..D .
v3: (Lucas)
- Add TODO: to clarify the disabling sequence on all D13+
- s/intel_dmc_has_fw_payload/has_dmc_id_fw/
- s/simple_flipq/flipq/
- s/_GEN12,_GEN13/TGL_,ADLP_/
- s/MAINDMC/DMC/
v4:
- Only disable flip queues on TGL/DG2, as on other platforms the
  corresponding event handlers don't exist.

39b1bc4b5b drm/i915: Rename block_size()/block_offset()
Give block_size()/block_offset() a "raw_" prefix since they
both operate on the "raw" (as in not duplicated) BDB block
contents.

What actually spurred this was a conflict between intel_bios.c
block_size() vs. block_size() from blkdev.h. That only
happened to me on a custom tree where we somehow manage to
include blkdev.h into intel_bios.c. But I think the rename
makes sense anyway to clarify the purpose of these functions.

0ea917819d drm/i915/dsi: fix VBT send packet port selection for ICL+
The VBT send packet port selection was never updated for ICL+ where the
2nd link is on port B instead of port C as in VLV+ DSI.

First, single link DSI needs to use the configured port instead of
relying on the VBT sequence block port. Remove the hard-coded port C
check here and make it generic. For reference, see commit f915084edc
("drm/i915: Changes related to the sequence port no for") for the
original VLV specific fix.

Second, the sequence block port number is either 0 or 1, where 1
indicates the 2nd link. Remove the hard-coded port C here for 2nd
link. (This could be a "find second set bit" on DSI ports, but just
check the two possible options.)

Third, sanity check the result with a warning to avoid a NULL pointer
dereference.

7b1d6924f2 drm/i915: Use i915_gem_object_ggtt_pin_ww for reloc_iomap
When removing short term pins, I've changed the the batch buffer
pinning for relocation to use __i915_vma_pin, because
i915_gem_object_ggtt_pin_ww was destroying the old vma. This
caused regressions, because the functions are not identical.

Fix the regressions by calling i915_gem_object_ggtt_pin_ww() again
on ggtt-only platforms, but only if the batch can be pinned without
being moved.

58606220a2 drm/i915: Fix CFI violation with show_dynamic_id()
When an attribute group is created with sysfs_create_group(), the
->sysfs_ops() callback is set to kobj_sysfs_ops, which sets the ->show()
callback to kobj_attr_show(). kobj_attr_show() uses container_of() to
get the ->show() callback from the attribute it was passed, meaning the
->show() callback needs to be the same type as the ->show() callback in
'struct kobj_attribute'.

However, show_dynamic_id() has the type of the ->show() callback in
'struct device_attribute', which causes a CFI violation when opening the
'id' sysfs node under drm/card0/metrics. This happens to work because
the layout of 'struct kobj_attribute' and 'struct device_attribute' are
the same, so the container_of() cast happens to allow the ->show()
callback to still work.

Change the type of show_dynamic_id() to match the ->show() callback in
'struct kobj_attributes' and update the type of sysfs_metric_id to
match, which resolves the CFI violation.

23dd74db02 drm/i915: Enable THP on Icelake and beyond
We have a statement from HW designers that the GPU read regression when
using 2M pages was fixed from Icelake onwards, which was also confirmed
by bencharking Eero did last year:

"""
When IOMMU is disabled, enabling THP causes following perf changes on
TGL-H (GT1):

    10-15% SynMark Batch[0-3]
    5-10% MemBW GPU texture, SynMark ShMapVsm
    3-5% SynMark TerrainFly* + Geom* + Fill* + CSCloth + Batch4
    1-3% GpuTest Triangle, SynMark TexMem* + DeferredAA + Batch[5-7]
          + few others
    -7% MemBW GPU blend

In the above 3D benchmark names, * means all the variants of tests with
the same prefix. For example "SynMark TexMem*", means both TexMem128 &
TexMem512 tests in the synthetic (Intel internal) SynMark test suite.

In the (public, but proprietary) GfxBench & GLB(enchmark) test suites,
there are both onscreen and offscreen variants of each test. Unless
explicitly stated otherwise, numbers are for both variants.

All tests are run with FullHD monitor. All tests are fullscreen except
for GLB and GpuTest ones, which are run in 1/2 screen window (GpuTest
triangle is run both in fullscreen and 1/2 screen window).
"""

Since the only regression is MemBW GPU blend, against many more gains,
it sounds it is time to enable THP on Gen11+.

56ca3117f7 drm/i915/huc: Don't fail the probe if HuC init fails
The previous patch introduced new failure cases in the HuC init flow
that can be hit by simply changing the config, so we want to avoid
failing the probe in those scenarios. HuC load failure is already
considered a non-fatal error and we have a way to report to userspace
if the HuC is not available via a dedicated getparam, so no changes
in expectation there.
The error message in the HuC init code has also been lowered to info to
avoid throwing error message for an expected behavior.

HuC loading has been moved from the GuC to the GSC. As part of the

In GuC submission mode the EU priority must be updated by the GuC rather
than the driver as the GuC owns the programming of the context descriptor.

Given that the GuC code uses the GuC priorities, we can't use a generic

The existing function has therefore been pushed to the execlists
back-end while a new one has been added for GuC.

a87d0a8476 drm/i915/bios: Generate LFP data table pointers if the VBT lacks them
Modern VBTs no longer contain the LFP data table pointers
block (41). We are expecting to have one in order to be able
to parse the LFP data block (42), so let's make one up.

Since the fp_timing table has variable size we must somehow
determine its size. Rather than just hardcode it we look for
the terminator bytes (0xffff) to figure out where each table
entry starts. dvo_timing, panel_pnp_id, and panel_name are
expected to have fixed size.

This has been observed on various machines, eg. TGL with BDB
version 240, CML with BDB version 231, etc. The most recent
VBT I've observed that still had block 41 had BDB version
228. So presumably the cutoff (if an exact cutoff even exists)
is somewhere around BDB version 229-231.

 2861 | static void intel_read_wm_latency(struct drm_i915_private *dev_priv,
      |             ^~~~~~~~~~~~~~~~~~~~~

by removing the over-specified array size from the argument declarations.

It seems that this code is actually safe because the size of the
array depends on the hardware generation, and the function checks
for that.

Notice that wm can be an array of 5 elements:
drivers/gpu/drm/i915/intel_pm.c:3109:   intel_read_wm_latency(dev_priv, dev_priv->wm.pri_latency);

or an array of 8 elements:
drivers/gpu/drm/i915/intel_pm.c:3131:   intel_read_wm_latency(dev_priv, dev_priv->wm.skl_latency);

and the compiler legitimately complains about that.

This helps with the ongoing efforts to globally enable
-Wstringop-overflow.

Backmerge tag 'v5.18-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into drm-next

Linux 5.18-rc5

There was a build fix for arm I wanted in drm-next, so backmerge rather then cherry-pick.

166c44e694 drm/i915/gt: Clear SET_PREDICATE_RESULT prior to executing the ring
Userspace may leave predication enabled upon return from the batch
buffer, which has the consequent of preventing all operation from the
ring from being executed, including all the synchronisation, coherency
control, arbitration and user signaling. This is more than just a local
gpu hang in one client, as the user has the ability to prevent the
kernel from applying critical workarounds and can cause a full GT reset.

We could simply execute MI_SET_PREDICATE upon return from the user
batch, but this has the repercussion of modifying the user's context
state. Instead, we opt to execute a fixup batch which by mixing
predicated operations can determine the state of the
SET_PREDICATE_RESULT register and restore it prior to the next userspace
batch. This allows us to protect the kernel's ring without changing the
uABI.

17be812e76 drm/i915/selftests: Skip poisoning SET_PREDICATE_RESULT on dg2
When predication is enabled all commands baring a few (such as MI_BB_END)
are nop'ed. If we accidentally enable predication while poisoning the
context, not only is the rest of the poisoning skipped (thus disabling
the test), but the closing instructions of the poison request are
nop'ed. Not only do we then not signal the waiting context, but we even
prevent re-enabling arbitration and the GPU will not perform a context
switch at the end of the request.

When bit 19 of MI_LOAD_REGISTER_IMM instruction opcode is set on tgl+
devices, HW does not care about certain register address offsets, but
instead check the following for valid address ranges on specific engines:
	RCS && CCS: BITS(0 - 10)
	BCS: BITS(0 - 11)
	VECS && VCS: BITS(0 - 13)
Also, tgl+ now support relative addressing for BCS engine - So, this
patch fixes issue with live_gt_lrc selftest that is failing where there is
mismatch between LRC register layout generated during init and HW
default register offsets.

c140915c00 drm/i915: move tons of power well initializers to rodata
Using compound literals for initialization can be tricky. Lacking a
const qualifier, they won't end up in rodata, which is probably not
expected or intended. Add const to move a whopping 136 initializers to
rodata.

Compare:

$ objdump --syms drivers/gpu/drm/i915/display/intel_display_power_map.o | grep "\.rodata.*__compound_literal"
$ objdump --syms drivers/gpu/drm/i915/display/intel_display_power_map.o | grep "\.data.*__compound_literal"

To avoid AUX timeouts and subsequent spurious hotplug interrupts, make
sure that the first DPCD access during detection is a read from an LTTPR
register.

Some ADLP DP link configuration at least with multiple LTTPRs expects
the first DPCD access during the LTTPR/DPCD detection after hotplug to
be a read from the LTTPR range starting with
DP_LT_TUNABLE_PHY_REPEATER_FIELD_DATA_STRUCTURE_REV. The side effect of
this read is to put each LTTPR into the LTTPR transparent or LTTPR
non-transparent mode.

The lack of the above read may leave some of the LTTPRs in non-LTTPR
mode, while other LTTPRs in LTTPR transparent or LTTPR non-transparent
mode (for instance LTTPRs after system suspend/resume that kept their
mode from before suspend). Due to the different AUX timeouts the
different modes imply, the DPCD access from a non-LTTPR range will
timeout and lead to an LTTPR generated hotplug towards the source (which
the LTTPR firmware uses to account for buggy TypeC adapters with a long
wake-up delay).

SYSCROS: 72939

v2: Keep DPCD read-out working on non-LTTPR platforms.
v3: Summarize what and why the patch does at the beginning of the commit
    log. (Jani)

The HDMI helpers were implemented in the EDID and connector code, but

Several of the HDMI helpers remain in EDID code because both share parts

We have now seen panel (XMG Core 15 e21 laptop) advertizing support
for Intel proprietary eDP backlight control via DPCD registers, but
actually working only with legacy pwm control.

This patch adds panel EDID check for possible HDR static metadata and
Intel proprietary eDP backlight control is used only if that exists.
Missing HDR static metadata is ignored if user specifically asks for
Intel proprietary eDP backlight control via enable_dpcd_backlight
parameter.

v2 :
- Ignore missing HDR static metadata if Intel proprietary eDP
  backlight control is forced via i915.enable_dpcd_backlight
- Printout info message if panel is missing HDR static metadata and
  support for Intel proprietary eDP backlight control is detected

There are two MEI interfaces in GSC: HECI1 and HECI2.

Both interfaces are on the BAR0 at offsets 0x00258000 and 0x00259000.
GSC is a GT Engine (class 4: instance 6). HECI1 interrupt is signaled
via bit 15 and HECI2 via bit 14 in the interrupt register.

This patch exports GSC as auxiliary device for mei driver to bind to
for HECI2 interface and prepares for HECI1 interface as
it will follow up soon.

b4b157577c drm/i915: Check EDID for HDR static metadata when choosing blc
We have now seen panel (XMG Core 15 e21 laptop) advertizing support
for Intel proprietary eDP backlight control via DPCD registers, but
actually working only with legacy pwm control.

This patch adds panel EDID check for possible HDR static metadata and
Intel proprietary eDP backlight control is used only if that exists.
Missing HDR static metadata is ignored if user specifically asks for
Intel proprietary eDP backlight control via enable_dpcd_backlight
parameter.

v2 :
- Ignore missing HDR static metadata if Intel proprietary eDP
  backlight control is forced via i915.enable_dpcd_backlight
- Printout info message if panel is missing HDR static metadata and
  support for Intel proprietary eDP backlight control is detected

Fixes: 4a8d79901d ("drm/i915/dp: Enable Intel's HDR backlight interface (only SDR for now)")

Save the initial HW state snapshot in i915 so that the rest code of GVT-g
can be moved into a dedicated module while it can still get a clean
initial HW state saved at the correct time during the initialization of
i915. The futhrer vGPU created by GVT-g will use this HW state as the
initial HW state.

v6:
- Remove the reference of intel_gvt_device_info.(Christoph)
- Refine the save_mmio() function. (Christoph)

i915_power_domains::lock. This patch also moves the
chy_phy_powergate_ch/lanes() functions to intel_display_power_well.c
which borrow the same lock to protect the DISPLAY_PHY_CONTROL register
state, which the HW uses both for toggling power wells and power gating
PHY lanes.

No functional change.

v2:
- Clarify in the commit log why CHV functions using the
  i915_power_domains::lock were moved, while others locking the power
  domain/well state were kept in intel_display_power.c . (Jouni)
- Move forward declaration of chv_phy_powergate_ch/lanes() to
  intel_display_power_well.h .

b962a06834 drm/i915: program wm blocks to at least blocks required per line
In configurations with single DRAM channel, for usecases like
4K 60 Hz, FIFO underruns are observed quite frequently. Looks
like the wm0 watermark values need to bumped up because the wm0
memory latency calculations are probably not taking the DRAM
channel's impact into account.

As per the Bspec 49325, if the ddb allocation can hold at least
one plane_blocks_per_line we should have selected method2.
Assuming that modern HW versions have enough dbuf to hold
at least one line, set the wm blocks to equivalent to blocks
per line.

dac3838109 drm/i915/guc: Enable Wa_22011802037 for gen12 GuC based platforms
Initiating a reset when the command streamer is not idle or in the
middle of executing an MI_FORCE_WAKE can result in a hang. Multiple
command streamers can be part of a single reset domain, so resetting one
would mean resetting all command streamers in that domain.

To workaround this, before initiating a reset, ensure that all command
streamers within that reset domain are either IDLE or are not executing
a MI_FORCE_WAKE.

Enable GuC PRE_PARSER WA bit so that GuC follows the WA sequence when
initiating engine-resets.

For gt-resets, ensure that i915 applies the WA sequence.

Opens to address in future patches:
- The part of the WA to wait for pending forcewakes is also applicable
  to execlists backend.
- The WA also needs to be applied for gen11

c837e02743 drm/i915/display/psr: Clear more PSR state during disable
After commit 805f04d42a ("drm/i915/display/psr: Use continuos full
frame to handle frontbuffer invalidations") was merged we started to
get some drm_WARN_ON(&dev_priv->drm, !(tmp & PSR2_MAN_TRK_CTL_ENABLE))
in tests that are executed in pipe B.

This is probably due psr2_sel_fetch_cff_enabled being left set during
PSR disable in the pipe A, so the PSR2_MAN_TRK_CTL write in
intel_psr2_program_trans_man_trk_ctl() is skipped in pipe B and then
we get the warning when actually enabling PSR after planes programing.
We don't get such warnings when running tests in pipe A because
PSR2_MAN_TRK_CTL is only cleared when enabling PSR2 with hardware
tracking.

Was not able to reproduce this issue but cleaning the PSR state
disable will not harm anything at all.

With some VRR panels, user can turn VRR ON/OFF on the fly from the panel settings.
When VRR is turned OFF ,sends a long HPD to the driver clearing the Ignore MSA bit
in the DPCD. Currently the driver parses that onevery HPD but fails to reset
the corresponding VRR Capable Connector property.
Hence the userspace still sees this as VRR Capable panel which is incorrect.

Fix this by explicitly resetting the connector property.

geometry and compute, two queries will need to exist. This introduces
the first, when passing a valid engine class and engine instance in the
flags returns a topology describing geometry.

Based on past discussion, we currently only support this new query item
on Xe_HP and beyond; earlier platforms do not need to worry about
geometry and compute pipelines having access to different topology and
should continue to use the existing topology query.

2584b3549f drm/i915/guc: Update to GuC version 70.1.1
The latest GuC firmware drops the context descriptor pool in favour of
passing all creation data in the create H2G. It also greatly simplifies
the work queue and removes the process descriptor used for multi-LRC
submission. So, remove all mention of LRC and process descriptors and
update the registration code accordingly.

Unfortunately, the new API also removes the ability to set default
values for the scheduling policies at context registration time.
Instead, a follow up H2G must be sent. The individual scheduling
policy update H2G commands are also dropped in favour of a single KLV
based H2G. So, change the update wrappers accordingly and call this
during context registration..

Of course, this second H2G per registration might fail due to being
backed up. The registration code has a complicated state machine to
cope with the actual registration call failing. However, if that works
then there is no support for unwinding if a further call should fail.
Unwinding would require sending a H2G to de-register - but that can't
be done because the CTB is already backed up.

So instead, add a new flag to say whether the context has a pending
policy update. This is set if the policy H2G fails at registration
time. The submission code checks for this flag and retries the policy
update if set. If that call fails, the submission path early exists
with a retry error. This is something that is already supported for
other reasons.

da0595ae91 drm/i915/migrate: Evict and restore the flatccs capable lmem obj
When we are swapping out the local memory obj on flat-ccs capable platform,
we need to capture the ccs data too along with main meory and we need to
restore it when we are swapping in the content.

When lmem object is swapped into a smem obj, smem obj will
have the extra pages required to hold the ccs data corresponding to the
lmem main memory. So main memory of lmem will be copied into the initial
pages of the smem and then ccs data corresponding to the main memory
will be copied to the subsequent pages of smem. ccs data is 1/256 of
lmem size.

Swapin happens exactly in reverse order. First main memory of lmem is
restored from the smem's initial pages and the ccs data will be restored
from the subsequent pages of smem.

Extracting and restoring the CCS data is done through a special cmd called
XY_CTRL_SURF_COPY_BLT

76a6d563db drm/i915/gem: Add extra pages in ttm_tt for ccs data
On Xe-HP and later devices, dedicated compression control state (CCS)
stored in local memory is used for each surface, to support the
3D and media compression formats.

The memory required for the CCS of the entire local memory is 1/256 of
the local memory size. So before the kernel boot, the required memory
is reserved for the CCS data and a secure register will be programmed
with the CCS base address

So when an object is allocated in local memory, dont need to explicitly
allocate the space for ccs data. But when the obj is evicted into the
smem, to hold the compression related data along with the obj extra space
is needed in smem. i.e obj_size + (obj_size/256).

Hence when a smem pages are allocated for an obj with lmem placement
possibility we create with the extra pages required for the ccs data for
the obj size.

v2:
  Used imperative wording [Thomas]
v3:
  Inflate the pages only when obj's placement is lmem only
v4:
  GEM_BUG_ON if the ttm->num_pages > obj page size [Thomas]

48760ffe92 drm/i915/gt: Clear compress metadata for Flat-ccs objects
Xe-HP and latest devices support Flat CCS which reserved a portion of
the device memory to store compression metadata, during the clearing of
device memory buffer object we also need to clear the associated
CCS buffer.

XY_CTRL_SURF_COPY_BLT is a BLT cmd used for reading and writing the
ccs surface of a lmem memory. So on Flat-CCS capable platform we use
XY_CTRL_SURF_COPY_BLT  to clear the CCS meta data.

b65cbb983f drm/i915/fbc: Introduce intel_fbc_sanitize()
Let's make sure FBC is always disabled when we start to take
over the hardware state.

I suspect this should never really happen, since the only time
when we really should be taking over with the display already
active is when the previous state was progammed by the BIOS,
which likely shouldn't use FBC. This could be driver init,
or S4 resume when the boot kernel doesn't load i915. But I
suppose no harm in keeping this code around for exra safety
since it's quite trivial.

29118f126a drm/i915/fbc: Remove intel_fbc_global_disable()
By the time intel_fbc_global_disable() gets called during driver
teardown we should have already disabled all the crtcs, so
no way FBC should be enabled at this point.

And I have no idea what the other user (i915_restore_display())
is even trying to achieve.

So let's just throw intel_fbc_global_disable() into the bin.

Don't issue a nuke from frontbuffer flush while a flip is pending.
This avoids the DSPADDR/DSPSURF rmw abuse from the pre-snb nuke
from racing with the DSPADDR/DSPSURF write being performed by
the flip/plane update. The flip itself will already cause the nuke
so a double nuke is redundant.
