This series provides some of the initial enablement patches for two
upcoming discrete GPUs:
* XeHP SDV: Xe_HP (version 12.50) graphics IP, no display IP
* DG2: Xe_HPG (version 12.55) graphics IP, Xe_LPD (version 13) display IP
Both platforms will need additional enablement patches beyond what's
present in this series before they're truly usable, including various
LMEM and GuC work that's already happening separately. The new
features/functionality that these platforms bring (such as multi-tile
support, dedicated compute engines, etc.) may be referenced in passing
in some of these patches but will be fully enabled in future series.

From: Lucas De Marchi <lucas.demarchi@intel.com>
Besides the arch version returned by GRAPHICS_VER(), new platforms
contain a "release id" to make clear the difference from one platform to
another. Although for the first ones we may use them as if they were a
major/minor version, that is not true for all platforms: we may have a
`release_id == n` that is closer to `n - 2` than to `n - 1`.
However the release id number is not defined by hardware until we start
using the GMD_ID register. For the platforms before that register is
useful we will set the values in software and we can set them as we
please. So the plan is to set them so we can group different features
under a single GRAPHICS_VER_FULL() check.
After GMD_ID is used, the usefulness of a "full version check" will be
greatly reduced and will be mostly used for deciding workarounds and a
few code paths. So it makes sense to keep it as a separate field from
graphics_ver.
Also, currently there is not much use for the release id in media and
display, so keep them out.
This is a mix of 2 independent changes: one by me and the other by Matt
Roper.

Hm this is a bit confusing. Is the sentence simply trying to say that,
as the release id number is growing, hw capabilities are not simply
accumulating but can be removed as well? Otherwise I am not sure how the
user of these macros is supposed to act on this sentence.

I get the VER and VER_FULL in the macros but could 'ver' and
'ver_release' here and in the code simply be renamed to 'ver'/'version'
and 'release'? Maybe it is just me but don't think I encountered the
term "version release" before.

Hm this is a bit confusing. Is the sentence simply trying to say that,
as the release id number is growing, hw capabilities are not simply
accumulating but can be removed as well? Otherwise I am not sure how the
user of these macros is supposed to act on this sentence.

I get the VER and VER_FULL in the macros but could 'ver' and
'ver_release' here and in the code simply be renamed to 'ver'/'version'
and 'release'? Maybe it is just me but don't think I encountered the
term "version release" before.

Just bikeshedding here, but I thought of:
if (info->grapics_ver_release)
drm_printf(p, "graphics_ver: %u.%u\n", info->graphics_ver, info->graphics_ver_release);
else
drm_printf(p, "graphics_ver: %u\n", info->graphics_ver);
Also, I thought "x_ver" and "x_ver_release" sounds a bit odd, perhaps
having "x_ver" and "x_rel" is more natural?
Ultimately I think we've historically always sucked at trying to figure
this out up front, so maybe the right answer is merging something and
fixing later...

Just bikeshedding here, but I thought of:
if (info->grapics_ver_release)
drm_printf(p, "graphics_ver: %u.%u\n", info->graphics_ver, info->graphics_ver_release);
else
drm_printf(p, "graphics_ver: %u\n", info->graphics_ver);

humn... a suggestion that I got internally a few week ago and I forgot
to update this was that this doesn't need to be abbreviated in debugfs
and could very well be:
drm_printf(p, "graphics version: %u\n", info->graphics_ver);
drm_printf(p, "graphics release: %u\n", info->graphics_ver_release);

Not sure what direction to go now though. Maybe trying to put all
suggestions together:
if (info->graphics_rel)
drm_printf(p, "graphics version: %u.%u\n", info->graphics_ver, info->graphics_rel);
else
drm_printf(p, "graphics version: %u\n", info->graphics_ver);
One thing I like is that doing `| grep "graphics version"`
gives all info you are searching for.

I already updated our local copy with all of this, so I'm fine including

XeHP-SDV and DG2. The additional register that commit
01eb15c9165e ("drm/i915: Add DISPLAY_VER() and related macros")
talks about is not available for these platforms. Here we hardcode them
in software to something that makes sense and it allows the driver to
be properly prepared for future platforms.

this is explaining why those numbers can't be interpreted as
major/minor and hence why here it's called "release" rather than
"minor".
Your interpretation is correct, except that a feature not being there
doesn't necessarily mean it got removed at some point. I might just had
never been in that particular release: i.e. GRAPHICS_VER_FULL() == 14.5
doesn't necessarily mean it comes after 14.3, with additional
features/fixes.

Our _FEATURES macro went back to GEN7, extending each other, making it
difficult to grasp what was really enabled/disabled. Take the
opportunity of the GEN -> XE_HP name break and also break with the
feature inheritance.
For XE_HP this basically goes from GEN12 back to GEN7 coalescing the
features making sure the overrides remain, remove all the
display-specific features and sort it.
Then also remove the definitions that would be overridden by
DGFX_FEATURES and those that were 0 (since that is the default).
Exception here is has_master_unit_irq: although it is a feature that
started with DG1 and is true for all DGFX platforms, it's also true for
XE_HP in general.

The current interrupt handler is getting increasingly complicated and
Xe_HP changes will bring even more complexity. Let's split off a new
interrupt handler starting with DG1 (i.e., when the master tile
interrupt register was added to the design) and use that as the basis
for the new Xe_HP changes.
Now that we track the hardware IP's release number as well as the
version number, we can also properly define DG1 has version "12.10" and
replace the has_master_unit_irq feature flag with an IP version test.

From: Matt Roper @ 2021-07-01 20:23 UTC (permalink / raw)
To: intel-gfx; +Cc: Paulo Zanoni, Lucas De Marchi, dri-devel
From: Paulo Zanoni <paulo.r.zanoni@intel.com>
The current interrupt handler is getting increasingly complicated and
Xe_HP changes will bring even more complexity. Let's split off a new
interrupt handler starting with DG1 (i.e., when the master tile
interrupt register was added to the design) and use that as the basis
for the new Xe_HP changes.
Now that we track the hardware IP's release number as well as the
version number, we can also properly define DG1 has version "12.10" and
replace the has_master_unit_irq feature flag with an IP version test.

So I know DG1 upstream is decidedly non-smooth, but basic
infrastructure we've had since forever ...
Why was this prep work not upstreamed earlier with some benign commit
message that doesn't mention DG2? There's zero DG2 stuff in here, this
could have landed months/years ago even. Bringing this up since right
this moment we have an internal chat about trees diverging a bit much.

history isn't linear and this commit, the way it is now, didn't exist 1
month ago, so your timescale is misleading. has_master_unit_irq was what
we thought we would need to share as much code as possible.
The biggest reason to fork the irq handler is actually not DG1 nor DG2,
but XEHPSDV and without those changes it would basically be a 95% copy
of the gen11 handler... for someone not looking to what is in the
pipeline, it can be a perfect argument to "consolidate these into a
single handler".

At least in the past we've done tons of upstream refactor prep for
exactly just these "prep for future platform" reasons. Everyone
understand that's necessary and generally trusts us we're not just
moving code for fun. But then 1-2 years ago we just kinda stopped
pushing prep work to upstream because everyone got way too busy with
other things, and now we're paying the price.
I mean even if the reason to fork it is a platform we can't even talk
about, the fork patch should go upstream way ahead so that there's
less patches in internal. Ideally platform enabling is zero code
shuffling, 100% just plugging code into existing neat places.

about, the fork patch should go upstream way ahead so that there's
less patches in internal. Ideally platform enabling is zero code
shuffling, 100% just plugging code into existing neat places.

we both know this is not the only reason and looking to the people in Cc
here my impression is you're preaching to the choir. Because the people
in Cc here either moved to other teams before there was something
working related to irq to share or continued to do prep work in upstream
as much as they can.

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
On Xe_HP the fusing register is renamed and changed to have the "enable"
semantics, but otherwise remains compatible (mmio address, bitmask
ranges) with older platforms.
To simplify things we do not add a new register definition but just stop
inverting the fusing masks before processing them.

In Gen12 there are various fuse combinations and in each configuration
vdbox engine may be connected to SFC depending on which engines are
available, so we need to set the SFC capability based on fuse value from
the hardware. Even numbered phyical instance always have SFC, odd
numbered physical instances have SFC only if previous even instance is
fused off.

considering that in TGL we have physical instances 0 and 2 (both even),
we can use this logic, so it's correct correct for GRAPHICS_VER(i915) == 12.
Although I wonder ifwe should be using MEDIA_VER(i915) here.

I'd be tempted to prefix the function name with gen11_ so it is clearer
it does not apply to earlier gens. Because if looking just at the diff
out of context below, one can wonder if there is a functional change or
not. There isn't, because there is a bailout for gen < 11 early in
init_engine_mask(), but perhaps gen11 function name prefix would make
this a bit more self-documenting.

Increasing the engine count causes a couple of local array variables
to exceed the kernel stack limit. So make them dynamic allocations
instead.

Increasing the engine count causes a couple of local array variables
to exceed the kernel stack limit. So make them dynamic allocations
instead.

this looks correctly, but apparently this test doesn't test anything as
`err` is write-only - there is only one read, but basically to avoid
overriding an earlier error.
looks like this should be `return err;` ?

This patch itself looks good.

u16 would be enough but it's probably pointless unless it makes it
better considering what I'll write next.
What I'd do is reorder the fields in struct intel_gt_info to avoid
padding, probably just pulling l3bank_mask up to be second is best.
Similar for struct intel_device_info because there's a ton of those and
so historically we were actually laying it out with care. A perfect
solution while keeping logical grouping might not be possible but worth
having a look.

u16 would be enough but it's probably pointless unless it makes it
better considering what I'll write next.
What I'd do is reorder the fields in struct intel_gt_info to avoid
padding, probably just pulling l3bank_mask up to be second is best.
Similar for struct intel_device_info because there's a ton of those and
so historically we were actually laying it out with care. A perfect
solution while keeping logical grouping might not be possible but worth
having a look.

Tvrtko

Xe_HP can have a lot of extra media engines. This patch adds the basic
definitions for them.
v2:
- Re-order intel_gt_info and intel_device_info slightly to avoid
unnecessary padding now that we've increased the size of
intel_engine_mask_t. (Tvrtko)

* [PATCH 11/53] drm/i915/xehp: Define multicast register ranges

Since we can't steer multicast register reads during ring-based
workaround verification, we need to define the multicast ranges where
failure to steer could potentially cause us to read back from a
fused-off register instance.
As with gen12, we can ignore the multicast ranges that the bspec
describes as 'SQIDI' since all instances of those registers will always
be present and we'll always be able to read back a workaround value that
was written with multicast.

Xe_HP is more modular then its predecessors and as a consequence it has
more types of replicated registers. As with l3bank regions on previous
platforms, we may need to explicitly re-steer accesses to these new
types of ranges at runtime if we can't find a single default steering
value that satisfies the fusing of all types.

types of ranges at runtime if we can't find a single default steering
value that satisfies the fusing of all types.

* [PATCH 15/53] drm/i915/xehp: Loop over all gslices for INSTDONE processing
2021-07-01 20:23 ` [Intel-gfx] " Matt Roper
@ 2021-07-01 20:23 ` Matt Roper

From: Matt Roper @ 2021-07-01 20:23 UTC (permalink / raw)
To: intel-gfx; +Cc: dri-devel
We no longer have traditional slices on Xe_HP platforms, but the
INSTDONE registers are replicated according to gslice representation
which is similar. We can mostly re-use the existing instdone code with
just a few modifications:
* Create an alternate instdone loop macro that will iterate over the
flat DSS space, but still provide the gslice/dss steering values for
compatibility with the legacy code.
* We should allocate INSTDONE storage space according to the maximum
number of gslices rather than the maximum number of legacy slices to
ensure we have enough storage space to hold all of the values. XeHP
design has 8 gslices, whereas older platforms never had more than 3
slices.

We no longer have traditional slices on Xe_HP platforms, but the
INSTDONE registers are replicated according to gslice representation
which is similar. We can mostly re-use the existing instdone code with
just a few modifications:
* Create an alternate instdone loop macro that will iterate over the
flat DSS space, but still provide the gslice/dss steering values for
compatibility with the legacy code.
* We should allocate INSTDONE storage space according to the maximum
number of gslices rather than the maximum number of legacy slices to
ensure we have enough storage space to hold all of the values. XeHP
design has 8 gslices, whereas older platforms never had more than 3
slices.

For new platforms we should be using the mechanisms in
intel_step.[ch]. As well as converting the old ones.

XeHP SDV is a Intel® dGPU without display. This is just the definition
of some basic platform macros, by large a copy of current state of
Tigerlake which does not reflect the end state of this platform.
v2:
- Switch to intel_step infrastructure for stepping matches. (Jani)

Xe_HP no longer has "slices" in the same way that old platforms did.
There are new concepts (gslices, cslices, mslices) that apply in various
contexts, but for the purposes of fusing slices no longer exist and we
just have one large pool of dual-subslices (DSS) to work with.
Furthermore, the meaning of the DSS fuse is inverted compared to past
platforms --- it now specifies which DSS are enabled rather than which
ones are disabled.

Due to the removal of legacy slices and the transition to a
gslice/cslice/mslice/etc. design, we'll internally store all DSS under
"slice0."

* [PATCH 19/53] drm/i915/xehpsdv: Add compute DSS type
2021-07-01 20:23 ` [Intel-gfx] " Matt Roper

Cc: Stuart Summers, Steve Hampson, Daniele Ceraolo Spurio, dri-devel
From: Stuart Summers <stuart.summers@intel.com>
Starting in XeHP, the concept of slice has been removed in favor of
DSS (Dual-Subslice) masks for various workload types. These workloads have
been divided into those enabled for geometry and those enabled for compute.
i915 currently maintains a single set of S/SS/EU masks for the device.
The goal of this patch set is to minimize the amount of impact to prior
generations while still giving the user maximum flexibility.

To: intel-gfx; +Cc: dri-devel
From: Stuart Summers <stuart.summers@intel.com>
Starting in XeHP, the concept of slice has been removed in favor of
DSS (Dual-Subslice) masks for various workload types. These workloads have
been divided into those enabled for geometry and those enabled for compute.
i915 currently maintains a single set of S/SS/EU masks for the device.
The goal of this patch set is to minimize the amount of impact to prior
generations while still giving the user maximum flexibility.

Like DG1, XeHP SDV doesn't have LLC/eDRAM control values due to being a
dgfx card. XeHP SDV adds 2 more bits: L3_GLBGO to "push the Go point to
memory for L3 destined transaction" and L3_LKP to "enable Lookup for
uncacheable accesses".

Like DG1, XeHP SDV doesn't have LLC/eDRAM control values due to being a
dgfx card. XeHP SDV adds 2 more bits: L3_GLBGO to "push the Go point to
memory for L3 destined transaction" and L3_LKP to "enable Lookup for
uncacheable accesses".

The RP_STATE_CAP register is no longer part of the MCHBAR on XEHPSDV; this
register is now a per-tile register at GTTMMADDR offset 0x250014.

* [PATCH 26/53] drm/i915/dg2: Add forcewake table
2021-07-01 20:23 ` [Intel-gfx] " Matt Roper
@ 2021-07-01 20:24 ` Matt Roper

To: intel-gfx; +Cc: Daniele Ceraolo Spurio, dri-devel
The DG2 forcewake table is very similar to the one used by XeHP SDV (and
both platforms are even presented as a single table in the bspec). For
the most part DG2 starts using a few additional ranges that were
'reserved' on XeHP SDV and stops using some others. However there is a
single range (0xd800-0xd87f) that needs to be handled differently
between the two platforms (it needs GT wake on XeHP SDV, but render wake
on DG2) so unless we want to wake both domains (which could waste power)
or define new types of forcewake domains for this special case we need
to have separate tables for the two platforms. Let's define the ranges
for both platforms with a parameterized macro so that we don't actually
need to duplicate everything in the code.
It should be fine for DG2 to re-use the Xe_HP shadow register list so we
can continue to use the 'xehpsdv' MMIO write functions and don't need to
spin up a separate DG2 instance.
Bspec: 66534

The DG2 forcewake table is very similar to the one used by XeHP SDV (and
both platforms are even presented as a single table in the bspec). For
the most part DG2 starts using a few additional ranges that were
'reserved' on XeHP SDV and stops using some others. However there is a
single range (0xd800-0xd87f) that needs to be handled differently
between the two platforms (it needs GT wake on XeHP SDV, but render wake
on DG2) so unless we want to wake both domains (which could waste power)
or define new types of forcewake domains for this special case we need
to have separate tables for the two platforms. Let's define the ranges
for both platforms with a parameterized macro so that we don't actually
need to duplicate everything in the code.
It should be fine for DG2 to re-use the Xe_HP shadow register list so we
can continue to use the 'xehpsdv' MMIO write functions and don't need to
spin up a separate DG2 instance.

DG2's replicated register ranges are almost the same at XeHP SDV with
the exception of one LNCF sub-range that switches to gslice steering.
We can re-use the XeHP SDV mslice steering table and just provide a
DG2-specific LNCF steering table.

* [PATCH 28/53] drm/i915/dg2: Add SQIDI steering

Although DG2_G10 platforms will always have all SQIDI's present and
don't need steering for registers in a SQIDI MMIO range, this isn't true
for DG2_G11 platforms; only SQIDI's 2 and 3 can be used on those.
We handle SQIDI ranges a bit differently from other types of explicit
steering. The SQIDI ranges belong to either the MCFG unit or the SF
unit, both of which have their own dedicated steering registers and do
not use the typical 0xFDC steering control that all other types of
ranges use. Thus we only need to worry about picking a valid initial
value for the MCFG and SF steering registers (0xFD0 and 0xFD8
resepectively) at driver init; they won't change after we set them up so
we don't need to worry about re-steering them explicitly at runtime.
Given that any SQIDI value should work fine for DG2-G10 and XeHP SDV,
while only values of 2 and 3 are valid for DG2-G11, we'll just
initialize the MCFG and SF steering registers to a constant value of "2"
for all XeHP-based platforms for simplicity --- that will work in all
cases.

ranges use. Thus we only need to worry about picking a valid initial
value for the MCFG and SF steering registers (0xFD0 and 0xFD8
resepectively) at driver init; they won't change after we set them up so
we don't need to worry about re-steering them explicitly at runtime.
Given that any SQIDI value should work fine for DG2-G10 and XeHP SDV,
while only values of 2 and 3 are valid for DG2-G11, we'll just
initialize the MCFG and SF steering registers to a constant value of "2"
for all XeHP-based platforms for simplicity --- that will work in all
cases.

New LRI register offsets were introduced for DG2, this patch adds
those extra registers, and create new register table for setting offsets
to compare with HW generated context image - especially for gt_lrc test.
Also updates general purpose register with scratch offset for DG2, in
order to use it for live_lrc_fixed selftest.

* [PATCH 30/53] drm/i915/dg2: Maintain backward-compatible nested batch behavior

For tgl+, the per-context setting of MI_MODE[12] determines whether
the bits of a nested MI_BATCH_BUFFER_START instruction should be
interpreted in the traditional manner or whether they should
instead use a new tgl+ meaning that breaks backward compatibility, but
allows nesting into 3rd-level batchbuffers. For previous platforms,
the hardware default for this register bit is to maintain
backward-compatible behavior unless a context intentionally opts into
the new behavior; however Xe_HPG flips the hardware default behavior.
From a SW perspective, we want to maintain the backward-compatible
behavior for userspace, so we'll apply a fake workaround to set it back
to the legacy behavior on platforms where the hardware default is to
break compatibility. At the moment there is no Linux userspace that
utilizes third-level batchbuffers, so this will avoid userspace from
needing to make any changes. using the legacy meaning is the correct
thing to do. If/when we have userspace consumers that want to utilize
third-level batch nesting, we can provide a context parameter to allow
them to opt-in.

Xe_HPG adds some additional INSTDONE_GEOM debug registers; the Mesa team
has indicated that having these reported in the error state would be
useful for debugging GPU hangs. These registers are replicated per-DSS
with gslice steering.

On DG2 we're supposed to just wait 600us after programming the well
before moving on; there won't be an ack from the hardware.

On DG2 we're supposed to just wait 600us after programming the well
before moving on; there won't be an ack from the hardware.

DG2 has outputs on DDI A-D attached to what the bspec diagram shows as
"Combo PHY A-D." Note that despite being labelled "combo" the PHYs on
these outputs are Synopsys PHYs rather than traditional Intel combo PHY
technology.

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...

Although the BW_BUDDY registers still exist, they are not used for
anything on DG2. This change is expected to hold true for future dgpu's
too.

DG2 doesn't have a SAGV or QGV points that determine memory bandwidth.
Instead it has a constant amount of memory bandwidth available to
display that does not need to be reduced based on the number of active
planes.
For simplicity, we'll just modify driver initialization to create a
single dummy QGV point with the proper amount of memory bandwidth,
rather than trying to query the pcode for this information.

DG2's SNPS PHYs incorporate a dedicated port PLL called MPLLB which
takes the place of the shared DPLLs we've used on past platforms. Let's
add the MPLLB programming sequences; they'll be plugged into the rest of
the code in future patches.

To: intel-gfx; +Cc: Jani Nikula, Nidhi Gupta, Lucas De Marchi, dri-devel
DG2's SNPS PHYs incorporate a dedicated port PLL called MPLLB which
takes the place of the shared DPLLs we've used on past platforms. Let's
add the MPLLB programming sequences; they'll be plugged into the rest of
the code in future patches.

* [PATCH 43/53] drm/i915/dg2: Add MPLLB programming for HDMI
2021-07-01 20:23 ` [Intel-gfx] " Matt Roper

From: Matt Roper @ 2021-07-01 20:24 UTC (permalink / raw)
To: intel-gfx; +Cc: Matt Atwood, dri-devel, Vandita Kulkarni
At the moment we don't have a proper algorithm that can be used to
calculate PHY settings for arbitrary HDMI link rates. The PHY tables
here should support the regular modes of real-world HDMI monitors.
Bspec: 54032

@ 2021-07-01 20:24 ` Matt Roper

To: intel-gfx; +Cc: dri-devel
At the moment we don't have a proper algorithm that can be used to
calculate PHY settings for arbitrary HDMI link rates. The PHY tables
here should support the regular modes of real-world HDMI monitors.
Bspec: 54032

value that corresponds to the voltage level from a table and program it
into the SNPS_PHY_TX_EQ register.

I've got some patches to turn this to the same ddi buf trans mechanism
that everything else uses. Seems like this patch tries to bypass it
because it's simple, but then we end up using encoder->get_buf_trans()
anyway, for example in intel_ddi_dp_voltage_max(), and it returns some
tgl buf trans tables... I guess it works by coincidence. :|
Anyway, as I said, I've got the patches, and I can fix this up
afterwards.
BR,

* [PATCH 45/53] drm/i915/dg2: Update modeset sequences

To: intel-gfx; +Cc: Lucas De Marchi, Anusha Srivatsa, dri-devel
DG2 has some changes to the expected modesetting sequences when compared
to gen12. Adjust our driver logic accordingly. Although the DP
sequence is pretty similar to TGL's, there are some steps that change,
so let's split the handling for that out into a separate function.

DG2 has some changes to the expected modesetting sequences when compared
to gen12. Adjust our driver logic accordingly. Although the DP
sequence is pretty similar to TGL's, there are some steps that change,
so let's split the handling for that out into a separate function.

Nitpick, this should really parametetrized the delay, 500 vs. 1200, not
add duplicate the code.

Nitpick, this should really parametetrized the delay, 500 vs. 1200, not
add duplicate the code.

DG2 has some changes to the expected modesetting sequences when compared
to gen12. Adjust our driver logic accordingly. Although the DP
sequence is pretty similar to TGL's, there are some steps that change,
so let's split the handling for that out into a separate function.
v2:
- Switch wait_for_us() -> _wait_for() so that we can parameterize the
timeout rather than duplicating the macro call. (Jani)

not sure I understand what was the request and what you did here really:
You basically turned
if (bla)
wait_for_us(x, C1)
else
wait_for_us(x, C2)
into
_wait_for(x, bla ? C1 : C2)
(you had to switch to _wait_for() because the argent is not not a constant
anymore).
When I read the comment I thought the request was to accept the delay as
a parameter in intel_wait_ddi_buf_active() because it would be called by
the different platforms, but that is wrong since
intel_wait_ddi_buf_active() is called in just one place, shared by the
current platforms.
So, in summary I don't know if this is what Jani was requesting, and if
it then I think this would make it slightly more readable:
int wait_max = IS_DG2(dev_priv) ? 1200 : 500;
...
if (wait_for_us(!(intel_de_read(dev_priv, DDI_BUF_CTL(port)) & DDI_BUF_IS_IDLE),
wait_max, 10, 10))
...
humn... in any case, this is minor for me:

but we should probably wait Jani to confirm what he meant by
"parameterize"

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.

Initialization of the PHY is handled by the hardware/firmware, but the
driver should wait up to 25ms for the PHY to report that its calibration
has completed.

To: intel-gfx; +Cc: Anusha Srivatsa, dri-devel, Gwan-gyeong Mun
From: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com>
The PSR enable/disable sequences now require that we program an extra
register in the PHY to adjust the lane disable power setting.

From: Anusha Srivatsa <anusha.srivatsa@intel.com>
DSC can be supported per DP connector. This patch creates
a per connector debugfs node to expose the Input and
Compressed BPP.
The same node can be used from userspace to force
DSC to a certain BPP.
force_dsc_bpp is written through this debugfs
node to force DSC BPP to all accepted values

DSC can be supported per DP connector. This patch creates
a per connector debugfs node to expose the Input and
Compressed BPP.
The same node can be used from userspace to force
DSC to a certain BPP.
force_dsc_bpp is written through this debugfs
node to force DSC BPP to all accepted values

I think this patch needs rework, and it's independent of the rest of the
series. Please just drop this one and the next.

From: Animesh Manna <animesh.manna@intel.com>
In verify_mpllb_state() encoder is retrieved from best_encoder
of connector_state. As there will be only one connector_state
for bigjoiner and checking encoder may not be needed for
bigjoiner-slave. This code path related to mpll is done on dg2
and need this fix to avoid null pointer dereference issue.
