Nathan Chancellor authored
When an attribute group is created with sysfs_create_group(), the ->sysfs_ops() callback is set to kobj_sysfs_ops, which sets the ->show() callback to kobj_attr_show(). kobj_attr_show() uses container_of() to get the ->show() callback from the attribute it was passed, meaning the ->show() callback needs to be the same type as the ->show() callback in 'struct kobj_attribute'. However, show_dynamic_id() has the type of the ->show() callback in 'struct device_attribute', which causes a CFI violation when opening the 'id' sysfs node under drm/card0/metrics. This happens to work because the layout of 'struct kobj_attribute' and 'struct device_attribute' are the same, so the container_of() cast happens to allow the ->show() callback to still work. Change the type of show_dynamic_id() to match the ->show() callback in 'struct kobj_attributes' and update the type of sysfs_metric_id to match, which resolves the CFI violation.

There are 2 ways an engine can get reset in i915 and the method of reset affects how KMD labels a context as guilty/innocent. (1) GuC initiated engine-reset: GuC resets a hung engine and notifies KMD. The context that hung on the engine is marked guilty and all other contexts are innocent. The innocent contexts are resubmitted. (2) GT based reset: When an engine heartbeat fails to tick, KMD initiates a gt/chip reset. All active contexts are marked as guilty and discarded. In order to correctly mark the contexts as guilty/innocent, pass a mask of engines that were reset to __guc_reset_context.

PVC adds extra blitter engines (in the following patch). The reset selftest has a local array on the stack which is sized by the number of engines. The increase pushes the size of this array to the point where it trips the 'stack too large' compile warning. This patch takes the allocation of the stack and makes it dynamic instead. v2 (MattR): - Minor cosmetic changes: re-sort definition and allocate using kmalloc_array().

If i915 does not want to use huge pages there is a) no point in setting up the private mount and b) should former fail, it is misleading to log THP support is disabled in the caller, which does not even know if callee tried to enable it.

Tvrtko Ursulin authored
We have a statement from HW designers that the GPU read regression when using 2M pages was fixed from Icelake onwards, which was also confirmed by bencharking Eero did last year: """ When IOMMU is disabled, enabling THP causes following perf changes on TGL-H (GT1): 10-15% SynMark Batch[0-3] 5-10% MemBW GPU texture, SynMark ShMapVsm 3-5% SynMark TerrainFly* + Geom* + Fill* + CSCloth + Batch4 1-3% GpuTest Triangle, SynMark TexMem* + DeferredAA + Batch[5-7] + few others -7% MemBW GPU blend In the above 3D benchmark names, * means all the variants of tests with the same prefix. For example "SynMark TexMem*", means both TexMem128 & TexMem512 tests in the synthetic (Intel internal) SynMark test suite. In the (public, but proprietary) GfxBench & GLB(enchmark) test suites, there are both onscreen and offscreen variants of each test. Unless explicitly stated otherwise, numbers are for both variants. All tests are run with FullHD monitor. All tests are fullscreen except for GLB and GpuTest ones, which are run in 1/2 screen window (GpuTest triangle is run both in fullscreen and 1/2 screen window). """ Since the only regression is MemBW GPU blend, against many more gains, it sounds it is time to enable THP on Gen11+. Signed-off-by:

The previous patch introduced new failure cases in the HuC init flow that can be hit by simply changing the config, so we want to avoid failing the probe in those scenarios. HuC load failure is already considered a non-fatal error and we have a way to report to userspace if the HuC is not available via a dedicated getparam, so no changes in expectation there. The error message in the HuC init code has also been lowered to info to avoid throwing error message for an expected behavior. Signed-off-by:

HuC loading via GSC is performed via a PXP command sent through the mei modules, so we need both MEI_GSC and MEI_PXP to be available. Given that the GSC will do both the transfer and the authentication, the legacy HuC loading paths can be safely skipped. Also note that the GSC-loaded HuC survives GT reset. v2: move the huc_is_authenticated() function to this patch. Signed-off-by:

Daniele Ceraolo Spurio authored
On newer platforms (starting DG2 G10 B-step and G11 A-step), ownership of HuC loading has been moved from the GuC to the GSC. As part of the change, the header format of the HuC binary has been updated and does not match the GuC anymore. The GSC will perform all the required checks on the binary size, so we only need to check that the version matches. Note that since we still haven't added any gsc-loaded FWs, the loaded_via_gsc variable will always be kept to its initialization value of zero. v2: Add a note about loaded_via_gsc being zero (Alan) Signed-off-by:

In GuC submission mode the EU priority must be updated by the GuC rather than the driver as the GuC owns the programming of the context descriptor. Given that the GuC code uses the GuC priorities, we can't use a generic function using i915 priorities for both execlists and GuC submission. The existing function has therefore been pushed to the execlists back-end while a new one has been added for GuC. v2: correctly use the GuC prio.
