[PATCH v3 00/13] i915: Prepare for Xe_HP compute engines

[PATCH v3 00/13] i915: Prepare for Xe_HP compute engines

[Matt Roper]

The Xe_HP architecture introduces compute engines as a new engine class.
These compute command streamers (CCS) are similar to the render engine,
except that they're intended for GPGPU usage and lack support for the 3D
pipeline.

For now we're just sending some initial "under the hood" preparation for
CCS engines without actually exposing them to userspace or adding them
to any platform's engine list yet.  There may be a bit more GuC-related
updates necessary before it's safe to expose them, so the actual uabi
bits will come later once that's all worked out.

v2:
 - General rebase of patches from September.
 - Drop ABI bits for now; we'll make it visible to userspace later once
   all the GuC work is hammered out.

v3:
 - Flip order of RCU_MODE patch and GuC's ADS update to enable compute
   engines.  (Daniele)
 - Replace fls(CCS_MASK) condition on fusing check with a simple IP
   version test to omit pre-Xe_HP platforms.
 - Fix a handful of checkpatch warnings.

[PATCH v3 02/13] drm/i915/xehp: CCS shares the render reset domain

[Matt Roper]

The reset domain is shared between render and all compute engines,
so resetting one will affect the others.

Note:  Before performing a reset on an RCS or CCS engine, the GuC will
attempt to preempt-to-idle the other non-hung RCS/CCS engines to avoid
impacting other clients (since some shared modules will be reset).  If
other engines are executing non-preemptable workloads, the impact is
unavoidable and some work may be lost.

[PATCH v3 03/13] drm/i915/xehp: Add Compute CS IRQ handlers

[Matt Roper]

Add execlists and GuC interrupts for compute CS into existing IRQ handlers.

All compute command streamers belong to the same compute class, so the
only change needed to enable their interrupts is to program their GT engine
interrupt mask registers.

CCS0 shares the register with CCS1, while CCS2 and CCS3 are in a new one.

[PATCH v3 04/13] drm/i915/xehp: compute engine pipe_control

[Matt Roper]

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

CCS will reuse the RCS functions for breadcrumb and flush emission.
However, CCS pipe_control has additional programming restrictions:
 - Command Streamer Stall Enable must be always set
 - Post Sync Operations must not be set to Write PS Depth Count
 - 3D-related bits must not be set

v2:
 - Drop unwanted blank line.  (Lucas)

[PATCH v3 05/13] drm/i915/xehp: CCS should use RCS setup functions

[Matt Roper]

The compute engine handles the same commands the render engine can
(except 3D pipeline), so it makes sense that CCS is more similar to RCS
than non-render engines.

The CCS context state (lrc) is also similar to the render one, so reuse
it. Note that the compute engine has its own CTX_R_PWR_CLK_STATE
register.

In order to avoid having multiple RCS && CCS checks, add the following
engine flag:
 - I915_ENGINE_HAS_RCS_REG_STATE - use the render (larger) reg state ctx.

[Intel-gfx] [PATCH v3 05/13] drm/i915/xehp: CCS should use RCS setup functions

[Matt Roper]

The compute engine handles the same commands the render engine can
(except 3D pipeline), so it makes sense that CCS is more similar to RCS
than non-render engines.

The CCS context state (lrc) is also similar to the render one, so reuse
it. Note that the compute engine has its own CTX_R_PWR_CLK_STATE
register.

In order to avoid having multiple RCS && CCS checks, add the following
engine flag:
 - I915_ENGINE_HAS_RCS_REG_STATE - use the render (larger) reg state ctx.

[PATCH v3 07/13] drm/i915/xehp: Define context scheduling attributes in lrc descriptor

[Matt Roper]

In Dual Context mode the EUs are shared between render and compute
command streamers. The hardware provides a field in the lrc descriptor
to indicate the prioritization of the thread dispatch associated to the
corresponding context.

The context priority is set to 'low' at creation time and relies on the
existing context priority to set it to low/normal/high.

[Intel-gfx] [PATCH v3 07/13] drm/i915/xehp: Define context scheduling attributes in lrc descriptor

[Matt Roper]

In Dual Context mode the EUs are shared between render and compute
command streamers. The hardware provides a field in the lrc descriptor
to indicate the prioritization of the thread dispatch associated to the
corresponding context.

The context priority is set to 'low' at creation time and relies on the
existing context priority to set it to low/normal/high.

We have to specify in the Render Control Unit Mode register
when CCS is enabled.

v2:
 - Move RCU_MODE programming to a helper function.  (Tvrtko)
 - Clean up and clarify comments.  (Tvrtko)
 - Add RCU_MODE to the GuC save/restore list.  (Daniele)
v3:
 - Move this patch before the GuC ADS update to enable compute engines;
   the definition of RCU_MODE and its insertion into the save/restore
   list moves to this patch.  (Daniele)

[PATCH v3 11/13] drm/i915/xehp: handle fused off CCS engines

[Matt Roper]

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

HW resources are divided across the active CCS engines at the compute
slice level, with each CCS having priority on one of the cslices.
If a compute slice has no enabled DSS, its paired compute engine is not
usable in full parallel execution because the other ones already fully
saturate the HW, so consider it fused off.

v2 (José):
 - moved it to its own function
 - fixed definition of ccs_mask

v3 (Matt):
 - Replace fls() condition with a simple IP version test

[PATCH v3 12/13] drm/i915/xehp: Add compute workarounds

[Matt Roper]

Additional workarounds are required once we start exposing CCS engines.

Note that we have a number of workarounds that update registers in the
shared render/compute reset domain.  Historically we've just added such
registers to the RCS engine's workaround list.  But going forward we
should be more careful to place such workarounds on a wa_list for an
engine that definitely exists and is not fused off (e.g., a platform
with no RCS would never apply the RCS wa_list).  We'll keep
rcs_engine_wa_init() focused on RCS-specific workarounds that only need
to be applied if the RCS engine is present.  A separate
general_render_compute_wa_init() function will be used to define
workarounds that touch registers in the shared render/compute reset
domain and that we need to apply regardless of what render and/or
compute engines actually exist.  Any workarounds defined in this new
function will internally be added to the first present RCS or CCS
engine's workaround list to ensure they get applied (and only get
applied once rather than being needlessly re-applied several times).

Registers that exist in the shared render/compute reset domain need to

re-applied whenever an RCS or CCS engine is reset.  We have a number of
workarounds (updating registers MLTICTXCTL, L3SQCREG1_CCS0,

implemented on the 'gt' workaround list and need to be moved

Why not just have guc_resume and execlist_resume call 
xehp_enable_ccs_engines(engine) for render case?

Also what happens if render itself is not present/fused-off (if there is 
such a thing)?

Just those questions, overall the patch looks fine as is:

That does seem like it would be simpler; I'll make that change and
resend.

There are still some patches that haven't been sent yet that switch some
of the various conditions to apply to an engine with
'I915_ENGINE_FIRST_RENDER_COMPUTE' rather than always to the RCS0
engine.  That will cover platforms where there is no render engine in
the design, as well as platforms where the render engine is part of the
architecture, but is fused off on some boards.

[PATCH v4 08/13] drm/i915/xehp: Enable ccs/dual-ctx in RCU_MODE

[Matt Roper]

We have to specify in the Render Control Unit Mode register
when CCS is enabled.

v2:
 - Move RCU_MODE programming to a helper function.  (Tvrtko)

[Intel-gfx] [PATCH v4 08/13] drm/i915/xehp: Enable ccs/dual-ctx in RCU_MODE

[Matt Roper]

We have to specify in the Render Control Unit Mode register
when CCS is enabled.

v2:
 - Move RCU_MODE programming to a helper function.  (Tvrtko)
 - Clean up and clarify comments.  (Tvrtko)
 - Add RCU_MODE to the GuC save/restore list.  (Daniele)
v3:
 - Move this patch before the GuC ADS update to enable compute engines;
   the definition of RCU_MODE and its insertion into the save/restore
   list moves to this patch.  (Daniele)
v4:
 - Call xehp_enable_ccs_engines() directly in guc_resume() and
   execlists_resume() rather than adding an extra layer of wrapping to
   the engine->resume() vfunc.  (Umesh)

[PATCH v5 11/13] drm/i915/xehp: handle fused off CCS engines

[Matt Roper]

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

HW resources are divided across the active CCS engines at the compute
slice level, with each CCS having priority on one of the cslices.
If a compute slice has no enabled DSS, its paired compute engine is not
usable in full parallel execution because the other ones already fully
saturate the HW, so consider it fused off.

v2 (José):
 - moved it to its own function
 - fixed definition of ccs_mask

v3 (Matt):
 - Replace fls() condition with a simple IP version test

v4 (Matt):
 - Don't try to calculate a ccs_mask using
   intel_slicemask_from_dssmask() until we've determined that we're
   running on an Xe_HP platform where the logic makes sense (and won't
   overflow).
