Prepare for making a distinction between not having display and having disabled display. Add INTEL_DISPLAY_ENABLED() and use it where HAS_DISPLAY() is used after intel_device_info_runtime_init(). This is initially duplication, as disabling display still leads to ->pipe_mask = 0 and HAS_DISPLAY() being false. Note that ever since i915.display_disable was introduced, it has not affected PCH detection even if it uses HAS_DISPLAY(), as display disable happens after that. Since INTEL_DISPLAY_ENABLED() will not make sense unless HAS_DISPLAY() is true, include a warning for catching misuses making decisions on INTEL_DISPLAY_ENABLED() when HAS_DISPLAY() is false. v2: Remove INTEL_DISPLAY_ENABLED() check from intel_detect_pch() (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

We see failures where the context continues executing past a preemption event, eventually leading to situations where a request has executed before we have event submitted it to HW! It seems like tgl is ignoring our RING_TAIL updates, but more likely is that there is a missing update required for our semaphore waits around preemption. v2: And disable internal semaphore usage Signed-off-by:

Since d0aa694b ("drm/i915/pmu: Always sample an active ringbuffer") the cost of sampling the engine state on execlists platforms became a little bit higher when both engine busyness and one of the wait states are being monitored. (Previously the busyness sampling on legacy platforms was done via seqno comparison so there was no cost of mmio read.) We can avoid that by skipping busyness sampling when engine supports software busy stats and so avoid the cost of potential mmio read and sample accumulation. Signed-off-by:

Reuse the same .modeset_calc_cdclk() function for all bxt+. The only difference in between the cnl/icl and the bxt variants is the call to cnl_compute_min_voltage_level(). We can do that call just fine on older platforms since they leave min_voltage_level[] zeroed. Let's rename the function to bxt_compute_min_voltage_level() just so it stays consistent with the rest of the naming scheme. Signed-off-by:

We're forgetting to mask off all three pipe select bits from the CDCLK_CTL value on icl+ which may lead to the extra bit being left in. That will cause us to consider the current hardware cdclk state as invalid, and we proceed to sanitize it even though the hardware may have active pipes and whatnot. Fix up the mask so we get rid of all three pipe select bits and thus hopefully no longer sanitize cdclk when it's already correctly programmed.

This allows userspace to use "legacy" mode for push constants, where they are committed at 3DPRIMITIVE or flush time, rather than being committed at 3DSTATE_BINDING_TABLE_POINTERS_XS time. Gen6-8 and Gen11 both use the "legacy" behavior - only Gen9 works in the "new" way. Conflating push constants with binding tables is painful for userspace, we would like to be able to avoid doing so.

The BXT and CNL functions were already basically identical, whereas ICL's function tried to do its own sanitization rather than calling bxt_sanitize_cdclk. This should actually fix a bug in our ICL initialization where it would consider the /2 CD2X divider invalid and force an unnecessary sanitization (we now have valid clock frequencies that use this divider).
