[Intel-gfx] [PATCH v2 00/50] Begin enabling Xe_HP SDV and DG2 platforms

[Matt Roper]

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.

v2:
 - General rebase and incorporation of r-b's.
 - Re-order intel_gt_info and intel_device_info structures to eliminate
   some unnecessary padding after the size change of
   intel_engine_mask_t.  (Tvrtko)
 - Use 'intel_step' mechanisms for revid->stepping mapping.  (Jani)
 - Drop the DSC patches for now; they need some rework.  (Jani)

[Intel-gfx] [PATCH v2 01/50] drm/i915: Add XE_HP initial definitions

[Matt Roper]

From: Lucas De Marchi <lucas.demarchi@intel.com>

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.

[Intel-gfx] [PATCH v2 02/50] drm/i915: Fork DG1 interrupt handler

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 03/50] drm/i915/xehp: VDBOX/VEBOX fusing registers are enable-based

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 04/50] drm/i915/gen12: Use fuse info to enable SFC

[Matt Roper]

From: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota@intel.com>

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 physical instance always have SFC, odd
numbered physical instances have SFC only if previous even instance is
fused off.

v2:
 - Minor style & typo fixes (Tvrtko)
 - Drop an unwanted 'inline' (Tvrtko)

[Intel-gfx] [PATCH v2 05/50] drm/i915/selftests: Allow for larger engine counts

[Matt Roper]

From: John Harrison <John.C.Harrison@Intel.com>

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

[Intel-gfx] [PATCH v2 06/50] drm/i915/xehp: Extra media engines - Part 1 (engine definitions)

[Matt Roper]

From: John Harrison <John.C.Harrison@Intel.com>

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)

[Intel-gfx] [PATCH v2 09/50] drm/i915/xehp: Xe_HP forcewake support

[Matt Roper]

Implement Xe_HP forcewake handling.  While we're at it, let's reorder to
the forcewake assignment if/else ladder to match our usual driver
conventions.

[Intel-gfx] [PATCH v2 10/50] drm/i915/xehp: Define multicast register ranges

[Matt Roper]

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.

Bspec: 66534

From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>

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.

[Intel-gfx] [PATCH v2 14/50] drm/i915/xehp: Loop over all gslices for INSTDONE processing

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 15/50] drm/i915/xehpsdv: add initial XeHP SDV definitions

[Matt Roper]

From: Lucas De Marchi <lucas.demarchi@intel.com>

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)

[Intel-gfx] [PATCH v2 16/50] drm/i915/xehp: Changes to ss/eu definitions

[Matt Roper]

From: Matthew Auld <matthew.auld@intel.com>

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.

[Intel-gfx] [PATCH v2 17/50] drm/i915/xehpsdv: Add maximum sseu limits

[Matt Roper]

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."

[Intel-gfx] [PATCH v2 18/50] drm/i915/xehpsdv: Add compute DSS type

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 20/50] drm/i915/xehpsdv: Define MOCS table for XeHP SDV

[Matt Roper]

From: Lucas De Marchi <lucas.demarchi@intel.com>

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".

[Intel-gfx] [PATCH v2 21/50] drm/i915/xehpsdv: factor out function to read RP_STATE_CAP

[Matt Roper]

From: Lucas De Marchi <lucas.demarchi@intel.com>

Instead of maintaining the same if ladder in 3 different places, add a
function to read RP_STATE_CAP.

[Intel-gfx] [PATCH v2 22/50] drm/i915/xehpsdv: Read correct RP_STATE_CAP register

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 23/50] drm/i915/dg2: add DG2 platform info

[Matt Roper]

DG2 has Xe_LPD display (version 13) and Xe_HPG (version 12.55) graphics.
There are two variants (treated as subplatforms in the code):  DG2-G10
and DG2-G11 that require independent programming in some areas (e.g.,
workarounds).

[Intel-gfx] [PATCH v2 25/50] drm/i915/dg2: Add forcewake table

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 26/50] drm/i915/dg2: Update LNCF steering ranges

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 27/50] drm/i915/dg2: Add SQIDI steering

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 28/50] drm/i915/dg2: Add new LRI reg offsets

[Matt Roper]

From: Akeem G Abodunrin <akeem.g.abodunrin@intel.com>

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.

[Intel-gfx] [PATCH v2 29/50] drm/i915/dg2: Maintain backward-compatible nested batch behavior

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 30/50] drm/i915/dg2: Report INSTDONE_GEOM values in error state

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 32/50] drm/i915/dg2: Add fake PCH

[Matt Roper]

As with DG1, DG2 has an ICL-style south display interface provided on
the same PCI device.  Add a fake PCH to ensure DG2 takes the appropriate
codepaths for south display handling.

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 37/50] drm/i915/dg2: Add dbuf programming

[Matt Roper]

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...

[Intel-gfx] [PATCH v2 38/50] drm/i915/dg2: Don't program BW_BUDDY registers

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 39/50] drm/i915/dg2: Don't read DRAM info

[Matt Roper]

DG2 does not use system DRAM information for BW_BUDDY programming or
watermark workarounds, so there's no need to read this out at startup.

[Intel-gfx] [PATCH v2 40/50] drm/i915/dg2: DG2 has fixed memory bandwidth

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 41/50] drm/i915/dg2: Add MPLLB programming for SNPS PHY

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 42/50] drm/i915/dg2: Add MPLLB programming for HDMI

[Matt Roper]

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

[Intel-gfx] [PATCH v2 43/50] drm/i915/dg2: Add vswing programming for SNPS phys

[Matt Roper]

Vswing programming for SNPS PHYs is just a single step -- look up the
value that corresponds to the voltage level from a table and program it
into the SNPS_PHY_TX_EQ register.

[Intel-gfx] [PATCH v2 44/50] drm/i915/dg2: Update modeset sequences

[Matt Roper]

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)

[Intel-gfx] [PATCH v2 45/50] drm/i915/dg2: Classify DG2 PHY types

[Matt Roper]

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.

[Intel-gfx] [PATCH v2 46/50] drm/i915/dg2: Wait for SNPS PHY calibration during display init

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.

[Intel-gfx] [PATCH v2 49/50] drm/i915/dg2: Update to bigjoiner path

[Matt Roper]

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.

I may be misreading this, but hw_id is only used by
RING_FAULT_REG() which is not actually used since
gen8... they are using GEN8_RING_FAULT_REG().

I'm having a hard time to understand what this comment "see
MI_SEMAPHORE_SIGNAL" actually means.


I'd just remove all these `.hw_id = 0, ...` together with the comment
since it will be zero-initiliazed.

I vaguely recall something about being told the hw_id field was used in 
semaphore messages from one engine to another. I.e. if engine X is 
blocked on a semaphore that is signalled by engine Y then the MI_ 
instruction executed on Y to do the signal needs to specify X as the 
target. Whereas, on newer hardware this requirement was no longer 
applicable because MI_SEMAPHORE_SIGNAL uses memory mailboxes instead of 
directed engine messages. Maybe that information was wrong or maybe that 
code has since been removed or reworked?

Yeah, the reason for explicitly setting it to zero was to avoid 
confusion over whether it had just been forgotten or not. I.e. to say 
'we know semaphores used to use this field but honest guv, we didn't 
forget to add it, it's just that newer hardware doesn't need it'.

makes sense... I just sent a patch series and Cc'ed you all
(https://patchwork.freedesktop.org/series/92797/) actually removing
hw_id. I have that feeling I'm missing something, but we can try to
simplify.

another weird thing in this... we are using XEHP_BSD5_RING_BASE, but we
set .graphics_ver to 11. Was that a typo? From bspec 11754 and 3293 it
seems the register is there, but it doesn't mean it can actually be used
according to bspec 21137 and 20189. So I guess it was either a typo or a
rebase issue and should be changed to graphics_ver = 12.

thanks
