| * drm/i915/gt: Clear SET_PREDICATE_RESULT prior to executing the ringChris Wilson2022-05-028-24/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

It also greatly simplifies the work queue and removes the process descriptor used for multi-LRC submission. So, remove all mention of LRC and process descriptors and update the registration code accordingly. Unfortunately, the new API also removes the ability to set default values for the scheduling policies at context registration time. Instead, a follow up H2G must be sent. The individual scheduling policy update H2G commands are also dropped in favour of a single KLV based H2G. So, change the update wrappers accordingly and call this during context registration.. Of course, this second H2G per registration might fail due to being backed up. The registration code has a complicated state machine to cope with the actual registration call failing. However, if that works then there is no support for unwinding if a further call should fail. Unwinding would require sending a H2G to de-register - but that can't be done because the CTB is already backed up. So instead, add a new flag to say whether the context has a pending policy update. This is set if the policy H2G fails at registration time. The submission code checks for this flag and retries the policy update if set. If that call fails, the submission path early exists with a retry error. This is something that is already supported for other reasons.

However the formats (bit positions, widths, registers and units) of these vary for different generations with even more variations arriving in the future. In order not to have to do identical computation for these caps in multiple places, here we centralize the computation of these caps. This makes the code cleaner and also more extensible for the future. v2: Clarify that caps are in "hw units" in comments (Lucas De Marchi) v3: Minor checkpatch fix v4: s/intel_rps_get_freq_caps/gen6_rps_get_freq_caps/ (Badal Nilawar) v5: Changes comments to kernel doc (Anshuman Gupta) Cc: Anshuman Gupta <anshuman.gupta@intel.com> Signed-off-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Reviewed-by: Badal Nilawar <badal.nilawar@intel.com> Acked-by: Anshuman Gupta <anshuman.gupta@intel.com> Signed-off-by: Anshuman Gupta <anshuman.gupta@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220406191848.20895-1-ashutosh.dixit@intel.com

By separating these calls and their static underlying functions to another area, we are able to compile out these functions for non-x86 builds and provide stubs for the non-x86 implementations. In addition to the problematic calls, we are moving the gmch-related functions to the new area.
