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).

Starting from ICL, the default for MIPI GPIO sequences seems to be using
native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse
many pins that quite frankly seem scary to poke based on the VBT
sequences. We pretty much have to trust that the board is configured
such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for
anything else.
MIPI sequence v4 also adds a flag to fall back to non-native sequences.

On ICP-ADP the pins used by the second PPS can be alternatively
muxed to some other function. In that case the second power
sequencer is unusable.
Unfortunately (on my ADL Thinkpad T14 gen3 at least) the
BIOS still likes to enable the VDD on the second PPS (due
to the VBT declaring the second bogus eDP panel) even when
not correctly muxed, so we need to deal with it somehow.
For now let's just initialize the PPS as normal, and then
use the normal eDP probe failure VDD off path to turn it off
(and release the wakeref the PPS init grabbed). The
alternative of just declaring that the platform has a single
PPS doesn't really work since it would cause the second eDP
probe to also try to use the first PPS and thus clobber the
state for the first (real) eDP panel.

If the GSC was loaded, the only way to stop it during the driver unload
flow is to do a driver-FLR.
The driver-initiated FLR is not the same as PCI config space FLR in
that it doesn't reset the SGUnit and doesn't modify the PCI config
space. Thus, it doesn't require a re-enumeration of the PCI BARs.
However, the driver-FLR does cause a memory wipe of graphics memory
on all discrete GPU platforms or a wipe limited to stolen memory
on the integrated GPU platforms.
We perform the FLR as the last action before releasing the MMIO bar, so
that we don't have to care about the consequences of the reset on the
unload flow.
v2: rename FLR function, add comment to explain FLR impact (Rodrigo),
better explain why GSC needs FLR (Alan)

Some gen2/gen3 parts have a 10bit gamma mode, on some pipes.
Expose it.
The format is different to the later i965+ style in that we
store a 10bit value and a 6 bit floating point slope for each
entry. Ie. the hardware extrapolates the intermediate steps
from the current LUT entry, instead of interpolating between
the current and next LUT entries. This also means we don't store
the last LUT entry in any register as it is defined by the previous
LUT entry's value+slope.
The slope has limited precision though (2 bit exponent + 4 bit
mantissa), so we'd have to allow for more error in the state checker
for the last entry and we have to make sure userspace doesn't
pass in something where the slope is simply to steep. In theory
we should perhaps check the slope for every interval, but we don't
do that for any other interpolated gamma mode and I suspect they
may also have some internal limit on the slope. I haven't confirmed
that theory though. Anyways, for ease of implementation we shall
just ignore the last entry in the state checker. If all the other
entries match anyway then that seems like a good indication that
the hardware was programmed as expected.

Current PSR code is supposed to use TRANSCODER_EDP to force 0 shift for
bits in PSR_IMR/IIR registers:
/*
* gen12+ has registers relative to transcoder and one per transcoder
* using the same bit definition: handle it as TRANSCODER_EDP to force
* 0 shift in bit definition
*/
At the time of writing the code assumption "TRANSCODER_EDP == 0" was made.
This is not the case and all fields in PSR_IMR and PSR_IIR are shifted
incorrectly if DISPLAY_VER >= 12.
Fix this by adding separate register field defines for >=12 and add bit
getter functions to keep code readability.

As an integrated GPU, MTL does not have local memory and HAS_LMEM()
returns false. However the platform's stolen memory is presented via
BAR2 (i.e., the BAR we traditionally consider to be the GMADR on IGFX)
and should be managed by the driver the same way that local memory is
on dgpu platforms (which includes setting the "lmem" bit on page table
entries). We use the term "local stolen memory" to refer to this
model.
The major difference from the traditional BAR2 (GMADR) is that
the stolen area is mapped via the BAR2 while in the former BAR2 is an
aperture into the GTT VA through which access are made into stolen area.
BSPEC: 53098, 63830
v2:
1. dropped is_dsm_invalid, updated valid_stolen_size check from Lucas

This patch adds the basic definitions needed to support
new copy engines. Also updating the cmd_info to accommodate
new engines, as the engine id's of legacy engines have been
changed.

- Add _BCS(n) definition, similar to other engines. (Tvrtko)
- Add I915_MAX_BCS definition, similar to other engnes. (Prathap)
- Move GVT change to avoid u16 overflow to its own patch. (Tvrtko)

The SoC registers, including RP_STATE_CAP, have moved to a new location
in GTTMMADR on Ponte Vecchio. We need to update the register offset
accordingly.

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.

Commit 428cb15d5b ("drm/i915: Clean up pre-skl primary plane registers")
introduced DISP_POS_Y and DISP_HEIGHT defines but accidentally set these
their masks to REG_GENMASK(31, 0) instead of REG_GENMASK(31, 16).
This breaks the primary display pane on at least pineview machines, fix
the mask to fix the primary display pane only showing black.
Tested on an Acer One AO532h with an Intel N450 SoC.

GSC is a graphics system controller, it provides
a chassis controller for graphics discrete cards.
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.
