* drm/nouveau: exec: report max pushs through getparamDanilo Krummrich2023-10-041-0/+10
| | | | | | | | | | | | | | | | | | | | | Report the maximum number of IBs that can be pushed with a single DRM_IOCTL_NOUVEAU_EXEC through DRM_IOCTL_NOUVEAU_GETPARAM. While the maximum number of IBs per ring might vary between chipsets, the kernel will make sure that userspace can only push a fraction of the maximum number of IBs per ring per job, such that we avoid a situation where there's only a single job occupying the ring, which could potentially lead to the ring run dry. Using DRM_IOCTL_NOUVEAU_GETPARAM to report the maximum number of IBs that can be pushed with a single DRM_IOCTL_NOUVEAU_EXEC implies that all channels of a given device have the same ring size.

* drm/nouveau: uapi: don't pass NO_PREFETCH flag implicitlyDanilo Krummrich2023-08-241-1/+7
| | | | | | | | | | | | | | | | | | | | Currently, NO_PREFETCH is passed implicitly through drm_nouveau_gem_pushbuf_push::length and drm_nouveau_exec_push::va_len. Since this is a direct representation of how the HW is programmed it isn't really future proof for a uAPI. Hence, fix this up for the new uAPI and split up the va_len field of struct drm_nouveau_exec_push, such that we keep 32bit for va_len and 32bit for flags. For drm_nouveau_gem_pushbuf_push::length at least provide NOUVEAU_GEM_PUSHBUF_NO_PREFETCH to indicate the bit shift. While at it, fix up nv50_dma_push() as well, such that the caller doesn't need to encode the NO_PREFETCH flag into the length parameter.

* | drm/nouveau: new VM_BIND uAPI interfacesDanilo Krummrich2023-08-041-0/+217
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit provides the interfaces for the new UAPI motivated by the Vulkan API. It allows user mode drivers (UMDs) to: 1) Initialize a GPU virtual address (VA) space via the new DRM_IOCTL_NOUVEAU_VM_INIT ioctl. UMDs can provide a kernel reserved VA area. 2) Bind and unbind GPU VA space mappings via the new DRM_IOCTL_NOUVEAU_VM_BIND ioctl. 3) Execute push buffers with the new DRM_IOCTL_NOUVEAU_EXEC ioctl. Both, DRM_IOCTL_NOUVEAU_VM_BIND and DRM_IOCTL_NOUVEAU_EXEC support asynchronous processing with DRM syncobjs as synchronization mechanism. The default DRM_IOCTL_NOUVEAU_VM_BIND is synchronous processing, DRM_IOCTL_NOUVEAU_EXEC supports asynchronous processing only.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new DRM_IOCTL_SYNCOBJ_EVENTFD IOCTL which signals an eventfd from a syncobj. This is useful for Wayland compositors to handle wait-before-submit. Wayland clients can send a timeline point to the compositor before the point has materialized yet, then compositors can wait for the point to materialize via this new IOCTL. The existing DRM_IOCTL_SYNCOBJ_TIMELINE_WAIT IOCTL is not suitable because it blocks. Compositors want to integrate the wait with their poll(2)-based event loop.

With that change caching policy can only be set at object creation time. The current code applies a default (platform dependent) cache setting for all objects. However this is not optimal for performance tuning. The patch extends the existing gem_create uAPI to let user set PAT index for the object at creation time. The new extension is platform independent, so UMD's can switch to using this extension for older platforms as well, while {set, get}_caching are still supported on these legacy paltforms for compatibility reason. However, since PAT index was not clearly defined for platforms prior to GEN12 (TGL), so we are limiting this externsion to GEN12+ platforms only. See ext_set_pat() in for the implementation details. The documentation related to the PAT/MOCS tables is currently available for Tiger Lake here: https://www.intel.com/content/www/us/en/docs/graphics-for-linux/developer-reference/1-0/tiger-lake.html The documentation for other platforms is currently being updated.

To do so, the huc authentication check is duplicated for GuC and GSC auth, with GSC-enabled binaries being considered fully authenticated only after the GSC auth step. To report the difference between the 2 auth steps, a new case is added to the HuC getparam. This way, the clear media driver can start submitting before full auth, as partial auth is enough for those workloads. v2: fix authentication status check for DG2 v3: add a better comment at the top of the HuC file to explain the different approaches to load and auth (John) v4: update call to intel_huc_is_authenticated in the pxp code to check for GSC authentication v5: drop references to meu and esclamation mark in huc_auth print (John) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Alan Previn <alan.previn.teres.alexis@intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Alan Previn <alan.previn.teres.alexis@intel.com> #v2 Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230531235415.1467475-5-daniele.ceraolospurio@intel.com

An actual real world customer stack has seen this happen in the 4-to-8 second range after the kernel starts (which sees MESA's init appear in the middle of this range as the compositor comes up). To avoid unncessary delays experienced by the UMD for get-caps purposes, add a GET_PARAM for I915_PARAM_PXP_SUPPORT. However, some failures can still occur after all the depedencies are met (such as firmware init flow failure, bios configurations or SOC fusing not allowing PXP enablement). Those scenarios will only be known to user space when it attempts creating a PXP context and is documented in the GEM UAPI headers. While making this change, create a helper that is common to both GET_PARAM caller and intel_pxp_start since the latter does similar checks.

While relooking at the ARB session creation flow in intel_pxp_start, let's address missing UAPI documentation. Without actually changing backward compatible behavior, update i915's drm-uapi comments that describe the possible error values when creating a context with I915_CONTEXT_PARAM_PROTECTED_CONTENT: Since the first merge of PXP support on ADL, i915 returns -ENXIO if a dependency such as firmware or component driver was yet to be loaded or returns -EIO if the creation attempt failed when requested by the PXP firmware (specific firmware error responses are reported in dmesg). Add MTL's function for ARB session invalidation but this reuses PXP firmware version 4.2 ABI structure format. For both cases, in the back-end gsccs functions for sending messages to the firmware inspect the GSC-CS-Mem-Header's pending-bit which means the GSC firmware is busy and we should retry. Given the last hw requirement, lets also update functions in front-end layer that wait for session creation or teardown completion to use new worst case timeout periods.

All reports from these engines are captured in the OA buffer managed by this OA unit. Current i915 OA implementation supports only the OAG unit. OAG primarily caters to render engine, so i915 OA uses render as the default engine in the OA implementation. Since there are more OA units on newer hardware that map to other engines, allow user to pass engine class and instance to select and program specific OA units.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The user might want to stall/resume engines to perform power testing for various scenarios. Because our current HL_CS_FLAGS_ENGINE_CORE_COMMAND command only handles the engines' cores, we need to add another opcode for handling entire engine and not just its core. The user supplies an array, where each entry holds the engine's ID and the command to send to the engine. The size of the array is limited by the number of engines in the ASIC (only Gaudi2 is currently supported).
