Normally, we try and skip submission if ELSP[1] is filled. However, we may desire to enable timeslicing due to the queue priority, even if ELSP[1] itself does not require timeslicing. That is the queue is equal priority to ELSP[0] and higher priority then ELSP[1]. Previously, we would wait until the context switch to preempt the current ELSP[1], but with timeslicing, we want to preempt ELSP[0] and replace it with the queue. In writing the test case, it become quickly apparent that we were also suppressing the tasklet during promotion and so failing to notice when the queue started requiring timeslicing.

Where the function, or code segment, operates on intel_gt, we need to start passing it instead of i915 to for_each_engine(_masked). This is another partial step in migration of i915->engines[] to gt->engines[]. Signed-off-by:

Tvrtko Ursulin authored
Medium term goal is to eliminate the i915->engine[] array and to get there we have recently introduced equivalent array in intel_gt. Now we need to migrate the code further towards this state. This next step is to eliminate usage of i915->engines[] from the for_each_engine_masked iterator. For this to work we also need to use engine->id as index when populating the gt->engine[] array and adjust the default engine set indexing to use engine->legacy_idx instead of assuming gt->engines[] indexing. v2: * Populate gt->engine[] earlier. * Check that we don't duplicate engine->legacy_idx v3: * Work around the initialization order issue between default_engines() and intel_engines_driver_register() which sets engine->legacy_idx for now. It will be fixed properly later. v4: * Merge with forgotten v2.5. Signed-off-by: -

The locks (active.lock and rq->lock) need to be taken with disabled interrupts. This is done in i915_request_retire() by disabling the interrupts independently of the locks itself. While local_irq_disable()+spin_lock() equals spin_lock_irq() on vanilla it does not on PREEMPT_RT. Chris Wilson confirmed that local_irq_disable() was just introduced as an optimisation to avoid enabling/disabling interrupts during lock/unlock combo. Enable/disable interrupts as part of the locking instruction. Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by:

The request selftests straddle the boundary between checking the driver and the hardware. They are subject to the quirks of the underlying HW, but operate on top of the backend abstractions. The tests focus on the scheduler elements and so should check for interactions of the scheduler across all exposed engines. Signed-off-by:

The MSA MISC computation now depends on the connector state, and we do it from the DDI .pre_enable() hook. All that is fine for DP SST but with MST we don't actually pass the connector state to the dig port's .pre_enable() hook which leads to an oops. Need to think more how to solve this in a cleaner fashion, but for now let's just add a NULL check to stop the oopsing.

With discrete graphics system can have both integrated and discrete GPU handled by i915. Currently we use a fixed name ("i915") when registering as the uncore PMU provider which stops working in this case. To fix this we add the PCI device name string to non-integrated devices handled by us. Integrated devices keep the legacy name preserving backward compatibility. v2: * Detect IGP and keep legacy name. (Michal) * Use PCI device name as suffix. (Michal, Chris) v3: * Constify the name. (Chris) * Use pci_domain_nr. (Chris) v4: * Fix kfree_const usage. (Chris) v5: * kfree_const does not work for modules. (Chris) * Changed is_igp helper to take i915. Signed-off-by:

The HW performs swizzling as part of its fence tiling inside the Global GTT. We already do the probing of the HW settings from the GGTT setup, complete the picture by storing the information as part of the GGTT. The primary benefit is the consistency of our probe routines do not break the i915_ggtt encapsulation. Signed-off-by:

Now that i915_ggtt knows everything about its own paths to perform mmio, we can use that as our primary backpointer for individual fence registers. This reduces the amount of pointer dancing we have to perform on the common paths, but more importantly finishes our fence register encapsulation. Signed-off-by:

Chris Wilson authored
Now that we record the default "goldenstate" context, we do not need to emit the mocs registers at the start of each context and can simply do mmio before the first context and capture the registers as part of its default image. As a consequence, this means that we repeat the mmio after each engine reset, fixing up any platform and registers that were zapped by the reset (for those platforms with global not context-saved settings).

The Jasper Lake PCH follows ICP/TGP's south display behavior and is identical to MCC graphics-wise except that it does not use the unusual (port C -> TC1) pin mapping that MCC does. Also, it turns out the extra PCH ID that we had previously thought was a form of MCC is actually a second ID for JSP (i.e., port C uses the port C pins instead of the TC1 pins). v2: - Also update the port masks (not just the pin table) in mcc_hpd_irq_setup. (Vivek) v3: - Break jsp_hpd_irq_setup out into its own function for clarity.

-
Ville Syrjälä authored
Once we do the hw vs. uapi split we can no longer use drm_atomic_helper_calc_timestamping_constants() as it'll consult the uapi state instead of the hw state. So let's just update the vblank timestamping constants whenever we update the scanline offset. We use both to convert the hw scanline count to something which matches the software timing values. First I thought to put these into intel_crtc_vblank_on() but we may want to get the scanline counter value before that (eg. from some early tracepoints), so let's stick to updating them a bit earlier than intel_crtc_vblank_on().

We perform timeslicing immediately upon receipt of a request that may be put into the second ELSP slot. The idea behind this was that since we didn't install the timer if the second ELSP slot was empty, we would not have any idea of how long ELSP[0] had been running and so giving the newcomer a chance on the GPU was fair. However, this causes us extra busy work that we may be able to avoid if we wait a jiffie for the first timeslice as normal. Signed-off-by:
