Cleanup intel_lrc.h by moving some of the residual common register definitions into intel_lrc_reg.h, prior to rebranding and splitting off the submission backends. v2: keep the SCHEDULE enum in the old file, since it is specific to the gvt usage of the execlists submission backend (John) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> #v2 Cc: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201209233618.4287-1-chris@chris-wilson.co.uk
2020-09-15drm/i915/gt: Use a mmio read of the CSB in case of failureChris Wilson1-0/+3
If we find the GPU didn't update the CSB within 50us, we currently fail and eventually reset the GPU. Lets report the value from the mmio space as a last resort, it may just stave off an unnecessary GPU reset.

2020-02-16drm/i915: Track hw reported context runtimeTvrtko Ursulin1-0/+1
GPU saves accumulated context runtime (in CS timestamp units) in PPHWSP which will be useful for us in cases when we are not able to track context busyness ourselves (like with GuC). Keep a copy of this in struct intel_context from where it can be easily read even if the context is not pinned. v2: (Chris) * Do not store pphwsp address in intel_context. * Log CS wrap-around. * Simplify calculation by relying on integer wraparound. v3: * Include total/avg in traces and error state for debugging Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20200216133620.394962-1-chris@chris-wilson.co.uk

2019-09-24drm/i915/selftests: Verify the LRC register layout between init and HWChris Wilson1-41/+21
Before we submit the first context to HW, we need to construct a valid image of the register state. This layout is defined by the HW and should match the layout generated by HW when it saves the context image. Asserting that this should be equivalent should help avoid any undefined behaviour and verify that we haven't missed anything important! Of course, having insisted that the initial register state within the LRC should match that returned by HW, we need to ensure that it does. v2: Drop the RELATIVE_MMIO flag from gen11, we ignore it for constructing the lrc image.

2019-09-10drm/i915/execlists: Clear STOP_RING bit on resetChris Wilson1-0/+2
During reset, we try to ensure no forward progress of the CS prior to the reset by setting the STOP_RING bit in RING_MI_MODE. Since gen9, this register is context saved and do we end up in the odd situation where we save the STOP_RING bit and so try to stop the engine again immediately upon resume. This is quite unexpected and causes us to complain about an early CS completion event!

2019-09-06drm/i915/tgl: Register state context definition for Gen12Michel Thierry1-1/+5
Gen12 has subtle changes in the reg state context offsets (some fields are gone, some are in a different location), compared to previous Gens. The simplest approach seems to be keeping Gen12 (and future platform) changes apart from the previous gens, while keeping the registers that are contiguous in functions we can reuse. v2: alias, virtual engine, rpcs, prune unused regs v3: use engine base (Daniele), take ctx_bb for all Bspec: 46255 Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Michel Thierry <michel.thierry@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Tested-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> [ickle: Tweaked the GEM_WARN_ON after settling on a compromise with Daniele] Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190906122314.2146-2-mika.kuoppala@linux.intel.com

2019-04-24drm/i915: Move GraphicsTechnology files under gt/Chris Wilson1-0/+68
Start partitioning off the code that talks to the hardware (GT) from the uapi layers and move the device facing code under gt/ One casualty is s/intel_ringbuffer.h/intel_engine.h/ with the plan to subdivide that header and body further (and split out the submission code from the ringbuffer and logical context handling). This patch aims to be simple motion so git can fixup inflight patches with little mess.
