2017-10-10drm/etnaviv: add infrastructure to query perf counterChristian Gmeiner1-1/+26
Make it possible that userspace can query all performance domains and its signals. This information is needed to sample those signals via submit ioctl. At the moment no performance domain is available. Changes from v1 -> v2: - use a 16 bit value for signals - fix padding issues - add id member to domain and signal struct Changes v4 -> v5 - provide for each pipe an own set of pm domains Signed-off-by: Christian Gmeiner <[email protected]> Signed-off-by: Lucas Stach <[email protected]>
2017-10-09drm/amdgpu: add interface for editing a foreign process's priority v3Andres Rodriguez1-0/+17
The AMDGPU_SCHED_OP_PROCESS_PRIORITY_OVERRIDE ioctls are used to set the priority of a different process in the current system. When a request is dropped, the process's contexts will be restored to the priority specified at context creation time. A request can be dropped by setting the override priority to AMDGPU_CTX_PRIORITY_UNSET. An fd is used to identify the remote process. This is simpler than passing a pid number, which is vulnerable to re-use, etc. This functionality is limited to DRM_MASTER since abuse of this interface can have a negative impact on the system's performance. v2: removed unused output structure v3: change refcounted interface for a regular set operation Signed-off-by: Andres Rodriguez <[email protected]> Acked-by: Christian König <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2017-10-09drm/amdgpu: add parameter to allocate high priority contexts v11Andres Rodriguez1-1/+9
Add a new context creation parameter to express a global context priority. The priority ranking in descending order is as follows: * AMDGPU_CTX_PRIORITY_HIGH_HW * AMDGPU_CTX_PRIORITY_HIGH_SW * AMDGPU_CTX_PRIORITY_NORMAL * AMDGPU_CTX_PRIORITY_LOW_SW * AMDGPU_CTX_PRIORITY_LOW_HW The driver will attempt to schedule work to the hardware according to the priorities. No latency or throughput guarantees are provided by this patch. This interface intends to service the EGL_IMG_context_priority extension, and vulkan equivalents. Setting a priority above NORMAL requires CAP_SYS_NICE or DRM_MASTER. v2: Instead of using flags, repurpose __pad v3: Swap enum values of _NORMAL _HIGH for backwards compatibility v4: Validate usermode priority and store it v5: Move priority validation into amdgpu_ctx_ioctl(), headline reword v6: add UAPI note regarding priorities requiring CAP_SYS_ADMIN v7: remove ctx->priority v8: added AMDGPU_CTX_PRIORITY_LOW, s/CAP_SYS_ADMIN/CAP_SYS_NICE v9: change the priority parameter to __s32 v10: split priorities into _SW and _HW v11: Allow DRM_MASTER without CAP_SYS_NICE Reviewed-by: Emil Velikov <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Andres Rodriguez <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2017-10-04drm/i915/scheduler: Support user-defined prioritiesChris Wilson1-0/+7
Use a priority stored in the context as the initial value when submitting a request. This allows us to change the default priority on a per-context basis, allowing different contexts to be favoured with GPU time at the expense of lower importance work. The user can adjust the context's priority via I915_CONTEXT_PARAM_PRIORITY, with more positive values being higher priority (they will be serviced earlier, after their dependencies have been resolved). Any prerequisite work for an execbuf will have its priority raised to match the new request as required. Normal users can specify any value in the range of -1023 to 0 [default], i.e. they can reduce the priority of their workloads (and temporarily boost it back to normal if so desired). Privileged users can specify any value in the range of -1023 to 1023, [default is 0], i.e. they can raise their priority above all overs and so potentially starve the system. Note that the existing schedulers are not fair, nor load balancing, the execution is strictly by priority on a first-come, first-served basis, and the driver may choose to boost some requests above the range available to users. This priority was originally based around nice(2), but evolved to allow clients to adjust their priority within a small range, and allow for a privileged high priority range. For example, this can be used to implement EGL_IMG_context_priority https://www.khronos.org/registry/egl/extensions/IMG/EGL_IMG_context_priority.txt EGL_CONTEXT_PRIORITY_LEVEL_IMG determines the priority level of the context to be created. This attribute is a hint, as an implementation may not support multiple contexts at some priority levels and system policy may limit access to high priority contexts to appropriate system privilege level. The default value for EGL_CONTEXT_PRIORITY_LEVEL_IMG is EGL_CONTEXT_PRIORITY_MEDIUM_IMG." so we can map PRIORITY_HIGH -> 1023 [privileged, will failback to 0] PRIORITY_MED -> 0 [default] PRIORITY_LOW -> -1023 They also map onto the priorities used by VkQueue (and a VkQueue is essentially a timeline, our i915_gem_context under full-ppgtt). v2: s/CAP_SYS_ADMIN/CAP_SYS_NICE/ v3: Report min/max user priorities as defines in the uapi, and rebase internal priorities on the exposed values.

2017-10-04drm/i915: Expand I915_PARAM_HAS_SCHEDULER into a capability bitmaskChris Wilson1-1/+8
In the next few patches, we wish to enable different features for the scheduler, some which may subtlety change ABI (e.g. allow requests to be reordered under different circumstances). So we need to make sure userspace is cognizant of the changes (if they care), by which we employ the usual method of a GETPARAM. We already have an I915_PARAM_HAS_SCHEDULER (which notes the existing ability to reorder requests to avoid bubbles), and now we wish to extend that to be a bitmask to describe the different capabilities implemented.

2017-08-29drm/syncobj: Add a signal ioctl (v3)Jason Ekstrand1-0/+1
This IOCTL provides a mechanism for userspace to trigger a sync object directly. There are other ways that userspace can trigger a syncobj such as submitting a dummy batch somewhere or hanging on to a triggered sync_file and doing an import. This just provides an easy way to manually trigger the sync object without weird hacks. The motivation for this IOCTL is Vulkan fences. Vulkan lets you create a fence already in the signaled state so that you can wait on it immediatly without stalling. We could also handle this with a new create flag to ask the driver to create a syncobj that is already signaled but the IOCTL seemed a bit cleaner and more generic. v2: - Take an array of sync objects (Dave Airlie) v3: - Throw -EINVAL if pad != 0 Signed-off-by: Jason Ekstrand <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

2017-08-29drm/syncobj: Allow wait for submit and signal behavior (v5)Jason Ekstrand1-0/+1
Vulkan VkFence semantics require that the application be able to perform a CPU wait on work which may not yet have been submitted. This is perfectly safe because the CPU wait has a timeout which will get triggered eventually if no work is ever submitted. This behavior is advantageous for multi-threaded workloads because, so long as all of the threads agree on what fences to use up-front, you don't have the extra cross-thread synchronization cost of thread A telling thread B that it has submitted its dependent work and thread B is now free to wait. Within a single process, this can be implemented in the userspace driver by doing exactly the same kind of tracking the app would have to do using posix condition variables or similar. However, in order for this to work cross-process (as is required by VK_KHR_external_fence), we need to handle this in the kernel. This commit adds a WAIT_FOR_SUBMIT flag to DRM_IOCTL_SYNCOBJ_WAIT which instructs the IOCTL to wait for the syncobj to have a non-null fence and then wait on the fence. Combined with DRM_IOCTL_SYNCOBJ_RESET, you can easily get the Vulkan behavior. v2: - Fix a bug in the invalid syncobj error path - Unify the wait-all and wait-any cases v3: - Unify the timeout == 0 case a bit with the timeout > 0 case - Use wait_event_interruptible_timeout v4: - Use proxy fence v5: - Revert to a combination of v2 and v3 - Don't use proxy fences - Don't use wait_event_interruptible_timeout because it just adds an extra layer of callbacks Signed-off-by: Jason Ekstrand <[email protected]> Cc: Dave Airlie <[email protected]> Cc: Chris Wilson <[email protected]> Cc: Christian König <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

2017-08-15drm/i915: Add support for drm syncobjsJason Ekstrand1-2/+29
This commit adds support for waiting on or signaling DRM syncobjs as part of execbuf. It does so by hijacking the currently unused cliprects pointer to instead point to an array of i915_gem_exec_fence structs which containe a DRM syncobj and a flags parameter which specifies whether to wait on it or to signal it. This implementation theoretically allows for both flags to be set in which case it waits on the dma_fence that was in the syncobj and then immediately replaces it with the dma_fence from the current execbuf. v2: - Rebase on new syncobj API v3: - Pull everything out into helpers - Do all allocation in gem_execbuffer2 - Pack the flags in the bottom 2 bits of the drm_syncobj* v4: - Prevent a potential race on syncobj->fence Testcase: igt/gem_exec_fence/syncobj* Signed-off-by: Jason Ekstrand <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Reviewed-by: Chris Wilson <[email protected]> Signed-off-by: Chris Wilson <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2017-08-10drm/i915: Implement .get_format_info() hook for CCSVille Syrjälä1-0/+20
SKL+ display engine can scan out certain kinds of compressed surfaces produced by the render engine. This involved telling the display engine the location of the color control surfae (CCS) which describes which parts of the main surface are compressed and which are not. The location of CCS is provided by userspace as just another plane with its own offset. By providing our own format information for the CCS formats, we should be able to make framebuffer_check() do the right thing for the CCS surface as well. Note that we'll return the same format info for both Y and Yf tiled format as that's what happens with the non-CCS Y vs. Yf as well. If desired, we could potentially return a unique pointer for each pixel_format+tiling+ccs combination, in which case we immediately be able to tell if any of that stuff changed by just comparing the pointers. But that does sound a bit wasteful space wise. v2: Drop the 'dev' argument from the hook v3: Include the description of the CCS surface layout v4: Pretend CCS tiles are regular 128 byte wide Y tiles (Jason) v5: Re-drop 'dev', fix commit message, add missing drm_fourcc.h description of CCS layout.

2017-07-28drm/vc4: Add an ioctl for labeling GEM BOs for summary statsEric Anholt1-0/+11
This has proven immensely useful for debugging memory leaks and overallocation (which is a rather serious concern on the platform, given that we typically run at about 256MB of CMA out of up to 1GB total memory, with framebuffers that are about 8MB ecah). The state of the art without this is to dump debug logs from every GL application, guess as to kernel allocations based on bo_stats, and try to merge that all together into a global picture of memory allocation state. With this, you can add a couple of calls to the debug build of the 3D driver and get a pretty detailed view of GPU memory usage from /debug/dri/0/bo_stats (or when we debug print to dmesg on allocation failure). The Mesa side currently labels at the gallium resource level (so you see that a 1920x20 pixmap has been created, presumably for the window system panel), but we could extend that to be even more useful with glObjectLabel() names being sent all the way down to the kernel. (partial) example of sorted debugfs output with Mesa labeling all resources: kernel BO cache: 16392kb BOs (3) tiling shadow 1920x1080: 8160kb BOs (1) resource 1920x1080@32/0: 8160kb BOs (1) scanout resource 1920x1080@32/0: 8100kb BOs (1) kernel: 8100kb BOs (1) v2: Use strndup_user(), use lockdep assertion instead of just a comment, fix an array[-1] reference, extend comment about name freeing.

This creates a new command submission chunk for amdgpu to add in and out sync objects around the submission. Sync objects are managed via the drm syncobj ioctls. The command submission interface is enhanced with two new chunks, one for syncobj pre submission dependencies, and one for post submission sync obj signalling, and just takes a list of handles for each. This is based on work originally done by David Zhou at AMD, with input from Christian Konig on what things should look like. In theory VkFences could be backed with sync objects and just get passed into the cs as syncobj handles as well. NOTE: this interface addition needs a version bump to expose it to userspace. TODO: update to dep_sync when rebasing onto amdgpu master. (with this - r-b from Christian) v1.1: keep file reference on import. v2: move to using syncobjs v2.1: change some APIs to just use p pointer. v3: make more robust against CS failures, we now add the wait sems but only remove them once the CS job has been submitted. v4: rewrite names of API and base on new syncobj code. v5: move post deps earlier, rename some apis v6: lookup post deps earlier, and just replace fences in post deps stage (Christian) Reviewed-by: Christian König <[email protected]> Signed-off-by: Dave Airlie <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
