Merge tag 'drm-next-2021-08-31-1' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

  Detailed summary:

  core:
   - extract i915 eDP backlight into core

6501e6bb14 drm/i915: Clean up gen2 DPLL readout
The current gen2 DPLL readout code:
* assumes i845/i865 have LVDS which is not true
* assumes only pipe B can drive LVDS (true, but makes
  the code appear a bit magical)
* hard to parse in general

Clean it up by checking for i85x (the only gen2 platform
with LVDS) and reusing intel_lvds_port_enabled().

Dithering BPC, with valid values of 6, 8, 10 BPC.
For ADLP+ these bits are used to set the PORT OUTPUT BPC, with valid
values of: 6, 8, 10, 12 BPC, and need to be programmed whether
dithering is enabled or not.

This patch:
-corrects the bits 5-7 for PIPE MISC register for 12 BPC.
-renames the bits and mask to have generic names for these bits for
dithering bpc and port output bpc.

v3: Added a note for MIPI DSI which uses the PIPE_MISC for readout
for pipe_bpp. (Uma Shankar)

v2: Added 'display' to the subject and fixes tag. (Uma Shankar)

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.

233624e0d5 drm/i915: Apply CMTG clock disabling WA while DPLL0 is enabled
CI test results/further experiments show that the workaround added in

commit 573d7ce4f6 ("drm/i915/adlp: Add workaround to disable CMTG clock gating")

can be applied only while DPLL0 is enabled. If it's disabled the
TRANS_CMTG_CHICKEN register is not accessible. Accordingly move the WA
to DPLL0 HW state sanitization and enabling.

This fixes an issue where the WA won't get applied (and a WARN is thrown
due to an unexpected value in TRANS_CMTG_CHICKEN) if the driver is
loaded without DPLL0 being enabled: booting without BIOS enabling an
output with this PLL, or reloading the driver.

While at it also add a debug print for the unexpected register value.

well. Adjusting the power domain accordingly to
POWER_DOMAIN_AUDIO_MMIO for audio detection and
POWER_DOMAIN_AUDIO_PLAYBACK for audio playback.

While doing this it requires to use POWER_DOMAIN_AUDIO_MMIO

573d7ce4f6 drm/i915/adlp: Add workaround to disable CMTG clock gating
The driver doesn't depend atm on the common mode timing generator
functionality (it would be used for some power saving feature and panel
timing synchronization), however DMC will corrupt the CMTG registers
across DC5 entry/exit sequences unless the CMTG clock gating is
disabled. This in turn can lead to at least the DPLL0/1 configuration
getting stuck at their last state, which means we can't reprogram them
to a new config.

Add the corresponding Bspec workaround to prevent the above.

instead of disable).

b4bde5554f drm/i915/display: split DISPLAY_VER 9 and 10 in intel_setup_outputs()
Commit 5a9d38b20a ("drm/i915/display: hide workaround for broken vbt
in intel_bios.c") moved the workaround for broken or missing VBT to
intel_bios.c. However is_port_valid() only protects the handling of
different skus of the same display version. Since in
intel_setup_outputs() we share the code path with version 9, this would
also create port F for SKL/KBL, which does not exist.

Missing VBT can be reproduced when starting a headless QEMU with no
opregion available.

Avoid the issue by splitting versions 9 and 10 in intel_setup_outputs(),
which also makes it more clear what code path it's taking for each
version.

3c73553f56 drm/i915: Program chicken bit during DP MST sequence on TGL+
A new step has been added to the DP modeset sequences for all platforms
with display version 12 and beyond:  if enabling DP MST with FEC, we
need to set a chicken bit before enabling the transcoder.  The chicken
bit should be disabled again before disabling the transcoder (which we
can do unconditionally since it shouldn't be set anyway in non-MST
cases).

fdc0b946a9 drm/i915/dg2: Classify DG2 PHY types
Although the bspec labels four of DG2's outputs as "combo PHY," the
underlying PHYs in both cases are actually Synopsys PHYs that are
programmed completely differently than the traditional Intel "combo" PHY
units.  As such, we don't want intel_phy_is_combo to take us down legacy
programming paths, so just return false from it on DG2.  Instead add a
new intel_phy_is_snps() that will return true for all DG2 PHYs.

76e50ea054 drm/i915/display: Fix shared dpll mismatch for bigjoiner slave
Currently when we do the HW state readout, we dont set the shared dpll to NULL
for the bigjoiner slave which should not have a DPLL assigned. So it has
some garbage while the HW state readout is NULL. So explicitly reset
the shared dpll for bigjoiner slave pipe.

a193477271 drm/i915/dsc: abstract helpers to get bigjoiner primary/secondary crtc
Add a single point of truth for figuring out the primary/secondary crtc
for bigjoiner instead of duplicating the magic pipe +/- 1 in multiple
places.

Also fix the pipe validity checks to properly take non-contiguous pipes
into account. The current checks may theoretically overflow
i915->pipe_to_crtc_mapping[pipe], albeit with a warning, due to fused
off pipes, as INTEL_NUM_PIPES() returns the actual number of pipes on
the platform, and the check is for INTEL_NUM_PIPES() == pipe + 1.

Prefer primary/secondary terminology going forward.

v2:
- Improved abstractions for pipe validity etc.

6d7a793aab drm/i915/display: Allow fastsets when DP_SDP_VSC infoframe do not match with PSR enabled
When PSR is enabled it handles DP_SDP_VSC, changing revision and all
the other fields as necessary.
It can also enabled and disable this SDP as needed without a full
modeset.

So here masking DP_SDP_VSC bit when previous and future state PSR
enabled, it will still be checked when comparing the asked state
to what was programmed to hardware.

9b2e49a148 drm/i915/display: Fix fastsets involving PSR
Commit 78b772e1a0 ("drm/i915/display: Fill PSR state during hardware
configuration read out") is not allowing fastsets to happen when PSR
states changes but PSR is a feature that can be enabled and disabled
during fastsets.

So here moving the PSR pipe conf checks to a block that is only
executed when checking if HW state matches with requested state, not
during the phase where it checks if fastset is possible or not.

There still a state mismatch not allowing fastsets between states
turning off or on PSR because of crtc_state->infoframes.enable
BIT(DP_SDP_VSC) but at least for now it will allow a fastset between
PSR1 <-> PSR2, that is a case heavilly used by CI due to pipe CRC not
work with PSR2, but the remaning issue will be fixed in a future patch.

d091fc53eb drm/i915/adl_p: Disable FIFO underrun recovery
The FIFO underrun recovery mechanism has a boatload of cases
where it can't be used. The description is also a bit ambiguous
as it doesn't specify whether plane downscaling needs to be considered
or just pipe downscaling. We may not even have sufficient state
tracking to decide this on demand, so for now just disable the
whole thing.

40e40e63f7 drm/i915/display: relax 2big checking around initial fb
The kernel prefers enabling fbc over the initial fb, since this leads to
actual runtime power savings, so if the initial fb is deemed too big
using some heuristic, then we simply skip allocating stolen for it.
However if the kernel is not configured with fbcon then it should be
possible to relax this, since unlike with fbcon the display server
shouldn't preserve it when later replacing it, and so we should be able
to re-use the stolen memory for fbc and friends. This patch is reported
to fix some flicker seen during boot splash on some devices.

ed2615a855 drm/i915/xelpd: Handle new location of outputs D and E
The DDI naming template for display version 12 went A-C, TC1-TC6.  With
XE_LPD, that naming scheme for DDI's has now changed to A-E, TC1-TC4.

The XE_LPD design keeps the register offsets and bitfields relating to
the TC outputs in the same location they were previously.  The new "D"
and "E" outputs now take the locations that were previously used by TC5
and TC6 outputs, or what we would have considered to be outputs "H" and
"I" under the legacy lettering scheme.

For the most part everything will just work as long as we initialize the
output with the proper 'enum port' value.  However we do need to take
care to pick the correct AUX channel when parsing the VBT (e.g., a
reference to 'AUX D' is actually asking us to use the 8th aux channel,
not the fourth).  We should also make sure that our encoders and aux
channels are named appropriately so that it's easier to correlate driver
debug messages with the bspec instructions.

v2:
 - Update handling of TGL_TRANS_CLK_SEL_PORT.  (Jose)

v3:
 - Add hpd_pin to handle outputs D and E (Jose)
 - Fixed conversion of BIOS port to aux ch for TC ports (Jose)

097d9e9020 drm/i915/display: remove strap checks from gen 9
Direction on gen9+ was to stop reading the straps and only rely on the
VBT for marking the port presence. This happened while dealing with
WaIgnoreDDIAStrap and instead of using it as a WA, it should now be the
normal flow. See commit 885d3e5b6f ("drm/i915/display: fix comment on
skl straps").

For gen 10 it's hard to say if this will work or not since I can't test
it, so leave it with the same behavior as before.

For PCH_TGP we should still rely on the VBT to make ports E and F not
available.

v2 (Ville):
  - use display ver >= 9 to make it consistent with the rest of the
    driver instead of checking for == 9
  - also handle CNL and only initialize port F if it is
    IS_CNL_WITH_PORT_F. Eventually CNL may be removed, but while it
    isn't let's keep it consistent everywhere

Since commit 45c0673aac ("drm/i915/bios: start using the
intel_bios_encoder_data directly") we lookup the devdata for each port
in intel_ddi_init() and just return if the port is not present in VBT

So in intel_display.c we don't have to check
intel_bios_is_port_present(), just rely on the check in
intel_ddi_init().

2ac5620fbe drm/i915/adl_p: Add stride restriction when using DPT
Alderlake-P have a new stride restriction when using DPT and it is used
by non linear framebuffers. Stride needs to be a power of two to take
full DPT rows, but stride is a parameter set by userspace.

What we could do is use a fake stride when doing DPT allocation so
HW requirements are met and userspace don't need to be changed to
met this power of two restrictions but this change will take a while
to be implemented so for now adding this restriction in driver to
reject atomic commits that would cause visual corruptions.

33e7a97510 drm/i915/xelpd: First stab at DPT support
Add support for DPT (display page table). DPT is a
slightly peculiar two level page table scheme used for
tiled scanout buffers (linear uses direct ggtt mapping
still). The plane surface address will point at a page
in the DPT which holds the PTEs for 512 actual pages.
Thus we require 1/512 of the ggttt address space
compared to a direct ggtt mapping.

We create a new DPT address space for each framebuffer and
track two vmas (one for the DPT, another for the ggtt).

TODO:
- Is the i915_address_space approaach sane?
- Maybe don't map the whole DPT to write the PTEs?
- Deal with remapping/rotation? Need to create a
  separate DPT for each remapped/rotated plane I
  guess. Or else we'd need to make the per-fb DPT
  large enough to support potentially several
  remapped/rotated vmas. How large should that be?

7c653e15e2 drm/i915: Reorder skl+ scaler vs. plane updates
When scanning out NV12 if we at any time have the plane enabled
while the scaler is disabled we get a pretty catastrophic
underrun.

Let's reorder the operations so that we try to avoid that happening
even if our vblank evade fails and the scaler enable/disable and
the plane enable/disable get latched during two diffent frames.

This takes care of the most common cases. I suppose there is still
at least a theoretical possibility of hitting this if one plane
takes the scaler away from another plane before the second plane
had a chance to set up another scaler for its use. But that
is starting to get a bit complicated, especially since the plane
commit order already has to be carefully sequenced to avoid any
dbuf overlaps. So plugging this 100% may prove somewhat hard...

The lockless power well handling is also racy, so this could

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)

5df7bd1308 drm/i915: skip display initialization when there is no display
Display features should not be initialized or de-initialized when there
is no display. Skip modeset initialization, output setup, plane, crtc,
encoder, connector registration, display cdclk and rawclk
initialization, display core initialization, etc.

Skip the functionality at as high level as possible, and remove any
redundant checks. If the functionality is conditional to *other* display
checks, do not add more. If the un-initialization has checks for
initialization, do not add more.

We explicitly do not care about any GMCH/VLV/CHV code paths, as they've
always had and will have display.

a4606d4595 drm/i915: Add support for FBs requiring a POT stride alignment
An upcoming platform has a restriction that the FB stride must be
power-of-two aligned. To support framebuffer layouts that are not in
this layout add a logic that pads the tile rows to the POT aligned size.

The HW won't read the padding PTEs, so these don't have to point to an
allocated address, or even have their valid flag set. So use a NULL PTE
instead for instance the scratch page, which is simple and keeps the SG
table compact.

v2:
- Simplify plane_view_dst_stride(). (Ville)
- Pass pitch_tiles as unsigned int.
v3:
- Drop unintentional s/plane_state->rotation/plane_config->rotation/

ee456a4ca5 drm/i915: Simplify copying the FB view state to the plane state
Instead of copying separately the GTT remapped and color plane view info
from the FB to the plane state, do this by copying the whole
intel_fb_view struct. For this we make sure the FB view state is fully
inited (that is also including the view type) already during FB
creation, so this init is not required during atomic check time. This
also means the we don't need to reset the unused color plane info during
atomic check, as these are already reset during FB creation.

I noticed that initial FBs will only work atm if they are page aligned
(which BIOS most probably always ensures), but add a comment to sanitize
this part once. Also we won't disable the plane if
get_initial_plane_config() failed for some reason (for instance due to
unsupported rotation), add a TODO: comment for this too.

61169987c4 drm/i915: Unify the FB and plane state view information into one struct
To allow the simplification of FB/plane view computation in the
follow-up patches, unify the corresponding state in the
intel_framebuffer and intel_plane_state structs into a new intel_fb_view
struct.

This adds some overhead to intel_framebuffer as the rotated view will
have now space for 4 color planes instead of the required 2 and it'll
also contain the unused offset for each color_plane info. Imo this is an
acceptable trade-off to get a simplified way of the remap computation.

Use the new intel_fb_view struct for the FB normal view as well, so (in
the follow-up patches) we can remove the special casing for normal view
calculation wrt. the calculation of remapped/rotated views. This also
adds an overhead to the intel_framebuffer struct, as the gtt remap info
and per-color plane offset/pitch is not required for the normal view,
but imo this is an acceptable trade-off as above. The per-color plane
pitch filed will be used by a follow-up patch, so we can retrieve the
pitch for each view in the same way.

No functional changes in this patch.

v2:
- Make the patch have _no functional change_.
  (fix skl_check_nv12_aux_surface() and skl_check_main_surface()).
- s/i915_color_plane_view::pitch/stride/ (Ville)

67f6f52af4 drm/i915: Stop adding planes to the commit needlessly
The dbuf bandwidth calculations don't need the planes to be
added to the state. Each plane's data rate has already been
precalculated and stored in the crtc state, and that with
the dbuf slice usage for each plane is all the dbuf bandwidth
code needs to figure out what the minimum cdclk is.

What we're trying to do here is make sure each plane recalculates
its minimum cdclk (ie. plane->min_cdclk()) on those platforms where
the number of active planes affects the result of said calculation.
Nothing to do with any dbuf cdclk requirements.

Not sure if we had stuff in slightly different order or what,
but at least in the current scheme this is not necessary.

02b64a4a0c drm/i915: Reject more ioctls for userptr, v2.
There are a couple of ioctl's related to tiling and cache placement,
that make no sense for userptr, reject those:
- i915_gem_set_tiling_ioctl()
    Tiling should always be linear for userptr. Changing placement will
    fail with -ENXIO.
- i915_gem_set_caching_ioctl()
    Userptr memory should always be cached. Changing caching mode will
    fail with -ENXIO.
- i915_gem_set_domain_ioctl()
    Still temporarily allowed to work as intended, it's used to check
    userptr validity. With the reworked userptr code, it will keep
    working for this usecase.

This plus the previous changes have been tested against beignet
by using its own unit tests, and intel-video-compute by using
piglit's opencl tests.

Changes since v1:
- set_domain was apparently used in iris for checking userptr validity,
  keep it working as intended.

ILK is the only platform that we consider "gen5" and SNB is the only
platform we consider "gen6."  Add an IS_SANDYBRIDGE() macro and then
replace numeric platform tests for these two generations with direct
platform tests with the following Coccinelle semantic patch:

351221ffc5 drm/i915: Move DDI clock readout to encoder->get_config()
Move the *_get_ddi_pll() stuff into the encodet->get_config() hook.
There it neatly sits next to the matching .{enable,disable}_clock()
functions.

In order to avoid excessive boilerplate I changed the behaviour
such that all platforms now do the readout via
crtc_state->port_dpll[].

ICL+ TC is still a bit special due to TBTPLL not having a functional
.get_freq(). Should probably change that by adopting the LCPLL
approach, but that would require a fairly substantial rework of the
DPLL ID handling. So leave it for later.

d0f1bfc615 drm/i915: Use pipes instead crtc indices in PLL state tracking
All the other places we have use pipes instead of crtc indices
when tracking resource usage. Life is easier when we do it
the same way always, so switch the dpll mgr to using pipes as
well. Looks like it was actually mixing these up in some cases
so it would not even have worked correctly except when the
device has a contiguous set of pipes starting from pipe A.
Granted, that is the typical case but supposedly it may not
always hold on modern hw.

e43539f87a drm/i915: Move pipe enable/disable tracepoints to intel_crtc_vblank_{on,off}()
On platforms/outputs without a working frame counter we rely
on the vblank code to cook up the frame counter from the timestamps.
That requires that vblank support is enabled. Thus we need to
move the pipe enable/disable tracepoints to the other side
of the drm_vblank_{on,off}() calls. There shouldn't really be
much happening between these old and new call sites so the
tracepoints should still provide reasonable data.

The alternative would be to give up on having the frame counter
values in the trace which would render the tracepoints more or
less pointless.

899f9d7bbc drm/i915: Readout conn_state->max_bpc
Populate conn_state->max_bpc with something sensible from the start.
Otherwise it's possible that we get to compute_sink_pipe_bpp() with
max_bpc==0.

The specific scenario goes as follows:
1. Initial connector state allocated with max_bpc==0
2. Trigger a modeset on the crtc feeding the connector, without
   actually adding the connector to the commit
3. drm_atomic_connector_check() is skipped because the
   connector has not yet been added, hence conn_state->max_bpc
   retains its current value
4. drm_atomic_helper_check_modeset() ->
   drm_atomic_add_affected_connectors() -> the connector
   is now part of the commit
5. compute_baseline_pipe_bpp() -> MISSING_CASE(max_bpc==0)

Note that pipe_bpp itself may not be populated on pre-g4x machines,
in which case we just fall back to max_bpc==8 and let .compute_config()
limit the resulting pipe_bpp further if necessary.

This does beg the deeper question of how much of the state

And should we even be doing the uapi->hw copy when

80cf9a8829 drm/i915: Disallow plane x+w>stride on ilk+ with X-tiling
ilk+ planes get notably unhappy when the plane x+w exceeds
the stride. This wasn't a problem previously because we
always aligned SURF to the closest tile boundary so the
x offset never got particularly large. But now with async
flips we have to align to 256KiB instead and thus this
becomes a real issue.

On ilk/snb/ivb it looks like the accesses just wrap
early to the next tile row when scanout goes past the
SURF+n*stride boundary, hsw/bdw suffer more heavily and
start to underrun constantly. i965/g4x appear to be immune.
vlv/chv I've not yet checked.

Let's borrow another trick from the skl+ code and search
backwards for a better SURF offset in the hopes of getting the
x offset below the limit. IIRC when I ran into a similar issue
on skl years ago it was causing the hardware to fall over
pretty hard as well.

And let's be consistent and include i965/g4x in the check
as well, just in case I just got super lucky somehow when
I wasn't able to reproduce the issue. Not that it really
matters since we still use 4k SURF alignment for i965/g4x
anyway.

f3243b75db drm/i915: move intel_init_audio_hooks inside display
intel_init_audio_hooks() sets up hooks in the display struct and only
makes sense when we have display. Move it inside
intel_init_display_hooks() so it isn't called when we don't have
display.

141b415f9f drm/i915/display: move register functions to display/
Now that all display-related functions are grouped in
i915_driver_register(), move them to display/ so we reduce the amount of
display calls from the rest of the driver.
