DRM_DEBUG_WARN_ON should only be used when we are certain CI is guaranteed to exercise a certain code path, so in case of values coming from MMIO reads we cannot be sure CI will have all the possible SKUs and parts. Use drm_warn instead and move logging to init phase while at it. v2: * GEM_WARN_ON in intel_gt_get_valid_steering. 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:

The function name is confusing, because it doesn't check the actual auth status in HW but the SW status. Given that there is only one user (the huc_auth function itself), just get rid of it and use the FW status checker directly. 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.

When bit 19 of MI_LOAD_REGISTER_IMM instruction opcode is set on tgl+ devices, HW does not care about certain register address offsets, but instead check the following for valid address ranges on specific engines: RCS && CCS: BITS(0 - 10) BCS: BITS(0 - 11) VECS && VCS: BITS(0 - 13) Also, tgl+ now support relative addressing for BCS engine - So, this patch fixes issue with live_gt_lrc selftest that is failing where there is mismatch between LRC register layout generated during init and HW default register offsets.

GSC is a graphics system controller, it provides a chassis controller for graphics discrete cards. There are two MEI interfaces in GSC: HECI1 and HECI2. Both interfaces are on the BAR0 at offsets 0x00258000 and 0x00259000. GSC is a GT Engine (class 4: instance 6). HECI1 interrupt is signaled via bit 15 and HECI2 via bit 14 in the interrupt register. This patch exports GSC as auxiliary device for mei driver to bind to for HECI2 interface and prepares for HECI1 interface as it will follow up soon.

Initiating a reset when the command streamer is not idle or in the middle of executing an MI_FORCE_WAKE can result in a hang. Multiple command streamers can be part of a single reset domain, so resetting one would mean resetting all command streamers in that domain. To workaround this, before initiating a reset, ensure that all command streamers within that reset domain are either IDLE or are not executing a MI_FORCE_WAKE. Enable GuC PRE_PARSER WA bit so that GuC follows the WA sequence when initiating engine-resets. For gt-resets, ensure that i915 applies the WA sequence.
