ssh://git.freedesktop.org/git/tegra/linux into drm-next drm/tegra: Changes for v5.15-rc1 The bulk of these changes is a more modern ABI that can be efficiently used on newer SoCs as well as older ones. The userspace parts for this are available here: - libdrm support: https://gitlab.freedesktop.org/tagr/drm/-/commits/drm-tegra-uabi-v8 - VAAPI driver: https://github.com/cyndis/vaapi-tegra-driver In addition, existing userspace from the grate reverse-engineering project has been updated to use this new ABI: - X11 driver: https://github.com/grate-driver/xf86-video-opentegra - 3D driver: https://github.com/grate-driver/grate Other than that, there's also support for display memory bandwidth management for various generations and a bit of cleanup.

ssh://git.freedesktop.org/git/drm/drm-intel into drm-next UAPI Changes: - Add I915_MMAP_OFFSET_FIXED On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid type. On devices without local memory, this caching mode is invalid. As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will be used, depending on the object placement on creation. WB will be used when the object can only exist in system memory, WC otherwise. Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888 - Reinstate the mmap ioctl for (already released) integrated Gen12 platforms Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is still to sunset the IOCTL even for integrated and require using mmap_offset. - Reject caching/set_domain IOCTLs on discrete Expected to become immutable property of the BO - Disallow changing context parameters after first use on Gen12 and earlier - Require setting context parameters at creation on platforms after Gen12 Rationale (for both): Allow less dynamic changes to the context to simplify the implementation and avoid user shooting theirselves in the foot. - Drop I915_CONTEXT_PARAM_RINGSIZE Userspace PR for compute-driver has not been merged - Drop I915_CONTEXT_PARAM_NO_ZEROMAP Userspace PR for libdrm / Beignet was never landed - Drop CONTEXT_CLONE API Userspace PR for Mesa was never landed - Drop getparam support for I915_CONTEXT_PARAM_ENGINES Only existed for symmetry wrt. setparam, never used. - Disallow bonding of virtual engines Drop the prep work, no hardware has been released needing it. - (Implicit) Disable gpu relocations Media userspace was the last userspace to still use them.

2021-08-05drm/i915/userptr: Probe existence of backing struct pages upon creationChris Wilson1-0/+20
Jason Ekstrand requested a more efficient method than userptr+set-domain to determine if the userptr object was backed by a complete set of pages upon creation. To be more efficient than simply populating the userptr using get_user_pages() (as done by the call to set-domain or execbuf), we can walk the tree of vm_area_struct and check for gaps or vma not backed by struct page (VM_PFNMAP). The question is how to handle VM_MIXEDMAP which may be either struct page or pfn backed... With discrete we are going to drop support for set_domain(), so offering a way to probe the pages, without having to resort to dummy batches has been requested. v2: - add new query param for the PROBE flag, so userspace can easily check if the kernel supports it(Jason). - use mmap_read_{lock, unlock}. - add some kernel-doc. v3: - In the docs also mention that PROBE doesn't guarantee that the pages will remain valid by the time they are actually used(Tvrtko). - Add a small comment for the hole finding logic(Jason). - Move the param next to all the other params which just return true.

2021-07-28drm/i915/guc: Implement GuC priority managementMatthew Brost1-0/+9
Implement a simple static mapping algorithm of the i915 priority levels (int, -1k to 1k exposed to user) to the 4 GuC levels. Mapping is as follows: i915 level < 0 -> GuC low level (3) i915 level == 0 -> GuC normal level (2) i915 level < INT_MAX -> GuC high level (1) i915 level == INT_MAX -> GuC highest level (0) We believe this mapping should cover the UMD use cases (3 distinct user levels + 1 kernel level). In addition to static mapping, a simple counter system is attached to each context tracking the number of requests inflight on the context at each level. This is needed as the GuC levels are per context while in the i915 levels are per request. v2: (Daniele) - Add BUILD_BUG_ON to enforce ordering of priority levels - Add missing lockdep to guc_prio_fini - Check for return before setting context registered flag - Map DISPLAY priority or higher to highest guc prio - Update comment for guc_prio Signed-off-by: Matthew Brost <matthew.brost@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210727002348.97202-33-matthew.brost@intel.com

The CPU domain should be static for discrete, and on DG1 we don't need any flushing since everything is already coherent, so really all this does is an object wait, for which we have an ioctl. Longer term the desired caching should be an immutable creation time property for the BO, which can be set with something like gem_create_ext. One other user is iris + userptr, which uses the set_domain to probe all the pages to check if the GUP succeeds, however we now have a PROBE flag for this purpose. v2: add some more kernel doc, also add the implicit rules with caching Suggested-by: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Cc: Jordan Justen <jordan.l.justen@intel.com> Cc: Kenneth Graunke <kenneth@whitecape.org> Cc: Jason Ekstrand <jason@jlekstrand.net> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Ramalingam C <ramalingam.c@intel.com> Reviewed-by: Ramalingam C <ramalingam.c@intel.com> Acked-by: Kenneth Graunke <kenneth@whitecape.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210715101536.2606307-5-matthew.auld@intel.com

The V3D engine has several hardware performance counters that can of interest for userspace performance analysis tools. This exposes new ioctls to create and destroy performance monitor objects, as well as to query the counter values. Each created performance monitor object has an ID that can be attached to CL/CSD submissions, so the driver enables the requested counters when the job is submitted, and updates the performance monitor values when the job is done. It is up to the user to ensure all the jobs have been finished before getting the performance monitor values. It is also up to the user to properly synchronize BCL jobs when submitting jobs with different performance monitors attached.

2021-07-08drm/i915: Drop the CONTEXT_CLONE API (v2)Jason Ekstrand1-13/+3
This API allows one context to grab bits out of another context upon creation. It can be used as a short-cut for setparam(getparam()) for things like I915_CONTEXT_PARAM_VM. However, it's never been used by any real userspace. It's used by a few IGT tests and that's it. Since it doesn't add any real value (most of the stuff you can CLONE you can copy in other ways), drop it. There is one thing that this API allows you to clone which you cannot clone via getparam/setparam: timelines. However, timelines are an implementation detail of i915 and not really something that needs to be exposed to userspace. Also, sharing timelines between contexts isn't obviously useful and supporting it has the potential to complicate i915 internally. It also doesn't add any functionality that the client can't get in other ways. If a client really wants a shared timeline, they can use a syncobj and set it as an in and out fence on every submit. v2 (Jason Ekstrand): - More detailed commit message Signed-off-by: Jason Ekstrand <jason@jlekstrand.net> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20210708154835.528166-7-jason@jlekstrand.net
2021-07-08drm/i915: Drop I915_CONTEXT_PARAM_NO_ZEROMAPJason Ekstrand1-0/+4
The idea behind this param is to support OpenCL drivers with relocations because OpenCL reserves 0x0 for NULL and, if we placed memory there, it would confuse CL kernels. It was originally sent out as part of a patch series including libdrm [1] and Beignet [2] support. However, the libdrm and Beignet patches never landed in their respective upstream projects so this API has never been used. It's never been used in Mesa or any other driver, either. Dropping this API allows us to delete a small bit of code.

2021-07-08drm/i915: Drop I915_CONTEXT_PARAM_RINGSIZEJason Ekstrand1-18/+2
This reverts commit 88be76cdafc7 ("drm/i915: Allow userspace to specify ringsize on construction"). This API was originally added for OpenCL but the compute-runtime PR has sat open for a year without action so we can still pull it out if we want. I argue we should drop it for three reasons: 1. If the compute-runtime PR has sat open for a year, this clearly isn't that important. 2. It's a very leaky API. Ring size is an implementation detail of the current execlist scheduler and really only makes sense there. It can't apply to the older ring-buffer scheduler on pre-execlist hardware because that's shared across all contexts and it won't apply to the GuC scheduler that's in the pipeline. 3. Having userspace set a ring size in bytes is a bad solution to the problem of having too small a ring. There is no way that userspace has the information to know how to properly set the ring size so it's just going to detect the feature and always set it to the maximum of 512K. This is what the compute-runtime PR does. The scheduler in i915, on the other hand, does have the information to make an informed choice. It could detect if the ring size is a problem and grow it itself. Or, if that's too hard, we could just increase the default size from 16K to 32K or even 64K instead of relying on userspace to do it. Let's drop this API for now and, if someone decides they really care about solving this problem, they can do it properly.

2021-06-04drm/panfrost: Add AFBC_FEATURES parameterAlyssa Rosenzweig1-0/+1
The value of the AFBC_FEATURES register is required by userspace to determine AFBC support on Bifrost. A user on our IRC channel (#panfrost) reported a workload that raised a fault on one system's Mali G31 but worked flawlessly with another system's Mali G31. We determined the cause to be missing AFBC support on one vendor's Mali implementation -- it turns out AFBC is optional on Bifrost! Whether AFBC is supported or not is exposed in the AFBC_FEATURES register on Bifrost, which reads back as 0 on Midgard. A zero value indicates AFBC is fully supported, provided the architecture itself supports AFBC, allowing backwards-compatibility with Midgard. Bits 0 and 15 indicate that AFBC support is absent for texturing and rendering respectively. The user experiencing the fault reports that AFBC_FEATURES reads back 0x10001 on their system, confirming the architectural lack of AFBC. Userspace needs this parameter to know to disable AFBC on that chip, and perhaps others. v2: Fix typo from copy-paste fail. v3: Bump the UABI version. This commit was cherry-picked from another series so chalking this up to a rebase fail.
