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. Fix both by restructuring the flow in i915_gemfs_init and at the same time note the failure to set it up in all cases. Signed-off-by:

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:

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.

Userspace may leave predication enabled upon return from the batch buffer, which has the consequent of preventing all operation from the ring from being executed, including all the synchronisation, coherency control, arbitration and user signaling. This is more than just a local gpu hang in one client, as the user has the ability to prevent the kernel from applying critical workarounds and can cause a full GT reset. We could simply execute MI_SET_PREDICATE upon return from the user batch, but this has the repercussion of modifying the user's context state. Instead, we opt to execute a fixup batch which by mixing predicated operations can determine the state of the SET_PREDICATE_RESULT register and restore it prior to the next userspace batch. This allows us to protect the kernel's ring without changing the uABI. Suggested-by:

When predication is enabled all commands baring a few (such as MI_BB_END) are nop'ed. If we accidentally enable predication while poisoning the context, not only is the rest of the poisoning skipped (thus disabling the test), but the closing instructions of the poison request are nop'ed. Not only do we then not signal the waiting context, but we even prevent re-enabling arbitration and the GPU will not perform a context switch at the end of the request.
