| | * drm/panfrost: Expose performance counters through unstable ioctlsBoris Brezillon2019-06-181-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Expose performance counters through 2 driver specific ioctls: one to enable/disable the perfcnt block, and one to dump the counter values. There are discussions to expose global performance monitors (those counters that can't be retrieved on a per-job basis) in a consistent way, but this is likely to take time to settle on something that works for various HW/users. The ioctls are marked unstable so we can get rid of them when the time comes. We initally went for a debugfs-based interface, but this was making the transition to per-FD address space more complicated (we need to specify the namespace the GPU has to use when dumping the perf counters), hence the decision to switch back to driver specific ioctls which are passed the FD they operate on and thus will have a dedicated address space attached to them. Other than that, the implementation is pretty simple: it basically dumps all counters and copy the values to a userspace buffer. The parsing is left to userspace which has to know the specific layout that's used by the GPU (layout differs on a per-revision basis).

| * drm/i915: Engine discovery queryTvrtko Ursulin2019-05-221-0/+42

A new query for the generic i915 query ioctl is added named DRM_I915_QUERY_ENGINE_INFO, together with accompanying structure drm_i915_query_engine_info. The address of latter should be passed to the kernel in the query.data_ptr field, and should be large enough for the kernel to fill out all known engines as struct drm_i915_engine_info elements trailing the query. As with other queries, setting the item query length to zero allows userspace to query minimum required buffer size. Enumerated engines have common type mask which can be used to query all hardware engines, versus engines userspace can submit to using the execbuf uAPI. Engines also have capabilities which are per engine class namespace of bits describing features not present on all engine instances. v2: * Fixed HEVC assignment. * Reorder some fields, rename type to flags, increase width.

| * drm/i915: Allow specification of parallel execbufChris Wilson2019-05-221-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a desire to split a task onto two engines and have them run at the same time, e.g. scanline interleaving to spread the workload evenly. Through the use of the out-fence from the first execbuf, we can coordinate secondary execbuf to only become ready simultaneously with the first, so that with all things idle the second execbufs are executed in parallel with the first. The key difference here between the new EXEC_FENCE_SUBMIT and the existing EXEC_FENCE_IN is that the in-fence waits for the completion of the first request (so that all of its rendering results are visible to the second execbuf, the more common userspace fence requirement). Since we only have a single input fence slot, userspace cannot mix an in-fence and a submit-fence. It has to use one or the other! This is not such a harsh requirement, since by virtue of the submit-fence, the secondary execbuf inherit all of the dependencies from the first request, and for the application the dependencies should be common between the primary and secondary execbuf.

| * drm/i915/execlists: Virtual engine bondingChris Wilson2019-05-221-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some users require that when a master batch is executed on one particular engine, a companion batch is run simultaneously on a specific slave engine. For this purpose, we introduce virtual engine bonding, allowing maps of master:slaves to be constructed to constrain which physical engines a virtual engine may select given a fence on a master engine. For the moment, we continue to ignore the issue of preemption deferring the master request for later. Ideally, we would like to then also remove the slave and run something else rather than have it stall the pipeline. With load balancing, we should be able to move workload around it, but there is a similar stall on the master pipeline while it may wait for the slave to be executed. At the cost of more latency for the bonded request, it may be interesting to launch both on their engines in lockstep. (Bubbles abound.) Opens: Also what about bonding an engine as its own master? It doesn't break anything internally, so allow the silliness. v2: Emancipate the bonds v3: Couple in delayed scheduling for the selftests v4: Handle invalid mutually exclusive bonding v5: Mention what the uapi does v6: s/nbond/num_bonds/ Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190521211134.16117-9-chris@chris-wilson.co.uk
| * drm/i915: Load balancing across a virtual engineChris Wilson2019-05-221-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having allowed the user to define a set of engines that they will want to only use, we go one step further and allow them to bind those engines into a single virtual instance. Submitting a batch to the virtual engine will then forward it to any one of the set in a manner as best to distribute load. The virtual engine has a single timeline across all engines (it operates as a single queue), so it is not able to concurrently run batches across multiple engines by itself; that is left up to the user to submit multiple concurrent batches to multiple queues. Multiple users will be load balanced across the system. The mechanism used for load balancing in this patch is a late greedy balancer. When a request is ready for execution, it is added to each engine's queue, and when an engine is ready for its next request it claims it from the virtual engine. The first engine to do so, wins, i.e. the request is executed at the earliest opportunity (idle moment) in the system. As not all HW is created equal, the user is still able to skip the virtual engine and execute the batch on a specific engine, all within the same queue. It will then be executed in order on the correct engine, with execution on other virtual engines being moved away due to the load detection. A couple of areas for potential improvement left! - The virtual engine always take priority over equal-priority tasks. Mostly broken up by applying FQ_CODEL rules for prioritising new clients, and hopefully the virtual and real engines are not then congested (i.e. all work is via virtual engines, or all work is to the real engine). - We require the breadcrumb irq around every virtual engine request. For normal engines, we eliminate the need for the slow round trip via interrupt by using the submit fence and queueing in order. For virtual engines, we have to allow any job to transfer to a new ring, and cannot coalesce the submissions, so require the completion fence instead, forcing the persistent use of interrupts. - We only drip feed single requests through each virtual engine and onto the physical engines, even if there was enough work to fill all ELSP, leaving small stalls with an idle CS event at the end of every request. Could we be greedy and fill both slots? Being lazy is virtuous for load distribution on less-than-full workloads though. Other areas of improvement are more general, such as reducing lock contention, reducing dispatch overhead, looking at direct submission rather than bouncing around tasklets etc. sseu: Lift the restriction to allow sseu to be reconfigured on virtual engines composed of RENDER_CLASS (rcs). v2: macroize check_user_mbz() v3: Cancel virtual engines on wedging v4: Commence commenting v5: Replace 64b sibling_mask with a list of class:instance v6: Drop the one-element array in the uabi v7: Assert it is an virtual engine in to_virtual_engine() v8: Skip over holes in [class][inst] so we can selftest with (vcs0, vcs2) Link: https://github.com/intel/media-driver/pull/283 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190521211134.16117-6-chris@chris-wilson.co.uk

Currently, they create a new context and iterate over which bits they want to copy across, but it would much more convenient if they were able to just pass in a target context to clone during creation. This essentially extends the setparam during creation to pull the details from a target context instead of the user supplied parameters. The ideal here is that we don't expose control over anything more than can be obtained via CONTEXT_PARAM. That is userspace retains explicit control over all features, and this api is just convenience. For example, you could replace struct context_param p = { .param = CONTEXT_PARAM_VM }; param.ctx_id = old_id; gem_context_get_param(&p.param); new_id = gem_context_create(); param.ctx_id = new_id; gem_context_set_param(&p.param); gem_vm_destroy(param.value); /* drop the ref to VM_ID handle */ with struct create_ext_param p = { { .name = CONTEXT_CREATE_CLONE }, .clone_id = old_id, .flags = CLONE_FLAGS_VM } new_id = gem_context_create_ext(&p); and not have to worry about stray namespace pollution etc. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190521211134.16117-5-chris@chris-wilson.co.uk

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Over the last few years, we have debated how to extend the user API to support an increase in the number of engines, that may be sparse and even be heterogeneous within a class (not all video decoders created equal). We settled on using (class, instance) tuples to identify a specific engine, with an API for the user to construct a map of engines to capabilities. Into this picture, we then add a challenge of virtual engines; one user engine that maps behind the scenes to any number of physical engines. To keep it general, we want the user to have full control over that mapping. To that end, we allow the user to constrain a context to define the set of engines that it can access, order fully controlled by the user via (class, instance). With such precise control in context setup, we can continue to use the existing execbuf uABI of specifying a single index; only now it doesn't automagically map onto the engines, it uses the user defined engine map from the context. v2: Fixup freeing of local on success of get_engines() v3: Allow empty engines[] v4: s/nengine/num_engines/ v5: Replace 64 limit on num_engines with a note that execbuf is currently limited to only using the first 64 engines. v6: Actually use the engines_mutex to guard the ctx->engines.

| * drm/i915: Restore control over ppgtt for context creation ABIChris Wilson2019-05-221-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having hid the partially exposed new ABI from the PR, put it back again for completion of context recovery. A significant part of context recovery is the ability to reuse as much of the old context as is feasible (to avoid expensive reconstruction). The biggest chunk kept hidden at the moment is fine-control over the ctx->ppgtt (the GPU page tables and associated translation tables and kernel maps), so make control over the ctx->ppgtt explicit. This allows userspace to create and share virtual memory address spaces (within the limits of a single fd) between contexts they own, along with the ability to query the contexts for the vm state.

The first available parameter is for querying the number of GPU faults (hangs) that can be attributed to the queue. This is useful for implementing context robustness. A user context can regularly query the number of faults to see if it is responsible for any and if so it can invalidate itself. This is also helpful for testing by confirming to the user driver if a particular command stream caused a fault (or not as the case may be).

However, with no CL to run it means that we need to do manual cache flushing of the L2 after the HW execution completes (for SSBO, atomic, and image_load_store writes that are the output of compute shaders). This doesn't yet expose the L2 cache's ability to have a region of the address space not write back to memory (which could be used for shared_var storage). So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing the ES31 tests), and on the kernel side on 7278 (failing atomic compswap tests in a way that doesn't reproduce on simpenrose). v2: Fix excessive allocation for the clean_job (reported by Dan Carpenter). Keep refs on jobs until clean_job is finished, to avoid spurious MMU errors if the output BOs are freed by userspace before L2 cleaning is finished.

GP is for OpenGL vertex shader processing and PP is for fragment shader processing. Each processor has its own MMU so prcessors work in virtual address space. - There's only one GP but multiple PP (max 4 for mali 400 and 8 for mali 450) in the same mali 4xx GPU. All PPs are grouped togather to handle a single fragment shader task divided by FB output tiled pixels. Mali 400 user space driver is responsible for assign target tiled pixels to each PP, but mali 450 has a HW module called DLBU to dynamically balance each PP's load. - User space driver allocate buffer object and map into GPU virtual address space, upload command stream and draw data with CPU mmap of the buffer object, then submit task to GP/PP with a register frame indicating where is the command stream and misc settings. - There's no command stream validation/relocation due to each user process has its own GPU virtual address space. GP/PP's MMU switch virtual address space before running two tasks from different user process. Error or evil user space code just get MMU fault or GP/PP error IRQ, then the HW/SW will be recovered. - Use GEM+shmem for MM. Currently just alloc and pin memory when gem object creation. GPU vm map of the buffer is also done in the alloc stage in kernel space. We may delay the memory allocation and real GPU vm map to command submission stage in the furture as improvement. - Use drm_sched for GPU task schedule. Each OpenGL context should have a lima context object in the kernel to distinguish tasks from different user. drm_sched gets task from each lima context in a fair way. mesa driver can be found here before upstreamed: https://gitlab.freedesktop.org/lima/mesa v8: - add comments for in_sync - fix ctx free miss mutex unlock v7: - remove lima_fence_ops with default value - move fence slab create to device probe - check pad ioctl args to be zero - add comments for user/kernel interface v6: - fix comments by checkpatch.pl v5: - export gp/pp version to userspace - rebase on drm-misc-next v4: - use get param interface to get info - separate context create/free ioctl - remove unused max sched task param - update copyright time - use xarray instead of idr - stop using drmP.h v3: - fix comments from kbuild robot - restrict supported arch to tested ones v2: - fix syscall argument check - fix job finish fence leak since kernel 5.0 - use drm syncobj to replace native fence - move buffer object GPU va map into kernel - reserve syscall argument space for future info - remove kernel gem modifier - switch TTM back to GEM+shmem MM - use time based io poll - use whole register name - adopt gem reservation obj integration - use drm_timeout_abs_to_jiffies Cc: Eric Anholt <eric@anholt.net> Cc: Rob Herring <robh@kernel.org> Cc: Christian König <ckoenig.leichtzumerken@gmail.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Alex Deucher <alexdeucher@gmail.com> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Rob Clark <robdclark@gmail.com> Cc: Dave Airlie <airlied@gmail.com> Signed-off-by: Andreas Baierl <ichgeh@imkreisrum.de> Signed-off-by: Erico Nunes <nunes.erico@gmail.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Simon Shields <simon@lineageos.org> Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com> Signed-off-by: Qiang Yu <yuq825@gmail.com> Reviewed-by: Eric Anholt <eric@anholt.net> Reviewed-by: Rob Herring <robh@kerrnel.org> Signed-off-by: Eric Anholt <eric@anholt.net> Link: https://patchwork.freedesktop.org/patch/291200/

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the unused DRM_DISPLAY_INFO_LEN from the uapi headers. I presume the original plan was to expose the display name via getconnector, but looks like that never happened. So we have the define for the length of the string but no string anywhere. A quick scan didn't seem to reveal userspace referencing this so hopefully we can just nuke it.
