2019-04-24lib/igt_dummyload: Clarify batch mappingMika Kuoppala
Use spin->condition to mark the spot we have saved for manipulating the looping condition. Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
2019-04-24lib/igt_dummyload: Introduce igt_spin_resetMika Kuoppala
Libify resetting a spin for reuse. v2: use also in perf_pmu v3: s/cmd_spin/cmd_precondition v4: remove early return for !spin (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
2019-04-18lib/igt_dummyload: Get rid of 'batch' on spinner accessorsMika Kuoppala
There is no guarantee that spinners are and will be implemented using batches. As we have igt_spin_t, manipulate it through igt_spin_* functions consistently and hide the batch nature.

2019-04-18lib/igt_dummyload: libify checks for spin batch activationMika Kuoppala
Instead of opencoding the poll into the spinner, use a helper to check if spinner has started. v2: use zero as presumed offset (Chris) v3: cleanup the relocs (Chris) v4: leave the domains to zero, avoid relocation (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
2019-03-29Revert "lib/igt_device: Move intel_get_pci_device under igt_device"Ville Syrjälä
One significant usecase for intel_reg/etc. is to be able to examine the hardware state *before* loading the driver. If the tool forces the driver to load we've totally lost that capability. This reverts commit 8ae86621d6fff60b6e20c6b0f9b336785c935b0f.

2019-03-28gem_exec_latency: Initialize variance to zeroPetri Latvala
It's just added to in a loop later without any initialization or direct assignment. Signed-off-by: Petri Latvala <petri.latvala@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
2019-03-20lib/igt_device: Move intel_get_pci_device under igt_deviceMichał Winiarski
It allows us to make things a little bit more generic. Also, we now require fd rather than doing guesswork when it comes to pci address. v2: Use readlinkat rather than string concat, move stuff around, provide a version that does not assert. (Chris) v3: Print addr on failure, avoid assignment in conditionals.

2019-02-12i915/gem_exec_latency: Eliminate the wakeup penaltyChris Wilson
The first dispatch incurs the cost of waking up the device, so also measure after issuing a spinner to keep the device awake as we submit. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Antonio Argenziano <antonio.argenziano@intel.com>

2018-10-23tests: Introduce i915 directoryArkadiusz Hiler
We can already move all the tests with distinct prefixes: gem_, gen3_ and i915_. pm_ and drv_ tests will follow in batches, so we can do the adjustments in the reporting/filtering layer of the CI system. v2: Fix test-list.txt generation with meson v3: Fix docs build (Petri) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Petri Latvala <petri.latvala@intel.com> Cc: Martin Peres <martin.peres@linux.intel.com> Signed-off-by: Arkadiusz Hiler <arkadiusz.hiler@intel.com> Reviewed-by: Petri Latvala <petri.latvala@intel.com> Tested-by: Petri Latvala <petri.latvala@intel.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Chris Wilson <chris@chris-wilson.co.uk>
