2019-02-05drm/i915: Expose RPCS (SSEU) configuration to userspace (Gen11 only)Tvrtko Ursulin1-0/+64
We want to allow userspace to reconfigure the subslice configuration on a per context basis. This is required for the functional requirement of shutting down non-VME enabled sub-slices on Gen11 parts. To do so, we expose a context parameter to allow adjustment of the RPCS register stored within the context image (and currently not accessible via LRI). If the context is adjusted before first use or whilst idle, the adjustment is for "free"; otherwise if the context is active we queue a request to do so (using the kernel context), following all other activity by that context, which is also marked as barrier for all following submission against the same context. Since the overhead of device re-configuration during context switching can be significant, especially in multi-context workloads, we limit this new uAPI to only support the Gen11 VME use case. In this use case either the device is fully enabled, and exactly one slice and half of the subslices are enabled. Example usage: struct drm_i915_gem_context_param_sseu sseu = { }; struct drm_i915_gem_context_param arg = { .param = I915_CONTEXT_PARAM_SSEU, .ctx_id = gem_context_create(fd), .size = sizeof(sseu), .value = to_user_pointer(&sseu) }; /* Query device defaults. */ gem_context_get_param(fd, &arg); /* Set VME configuration on a 1x6x8 part. */ sseu.slice_mask = 0x1; sseu.subslice_mask = 0xe0; gem_context_set_param(fd, &arg); v2: Fix offset of CTX_R_PWR_CLK_STATE in intel_lr_context_set_sseu() (Lionel) v3: Add ability to program this per engine (Chris) v4: Move most get_sseu() into i915_gem_context.c (Lionel) v5: Validate sseu configuration against the device's capabilities (Lionel) v6: Change context powergating settings through MI_SDM on kernel context (Chris) v7: Synchronize the requests following a powergating setting change using a global dependency (Chris) Iterate timelines through dev_priv.gt.active_rings (Tvrtko) Disable RPCS configuration setting for non capable users (Lionel/Tvrtko) v8: s/union intel_sseu/struct intel_sseu/ (Lionel) s/dev_priv/i915/ (Tvrtko) Change uapi class/instance fields to u16 (Tvrtko) Bump mask fields to 64bits (Lionel) Don't return EPERM when dynamic sseu is disabled (Tvrtko) v9: Import context image into kernel context's ppgtt only when reconfiguring powergated slice/subslices (Chris) Use aliasing ppgtt when needed (Michel) Tvrtko Ursulin: v10: * Update for upstream changes. * Request submit needs a RPM reference. * Reject on !FULL_PPGTT for simplicity. * Pull out get/set param to helpers for readability and less indent. * Use i915_request_await_dma_fence in add_global_barrier to skip waits on the same timeline and avoid GEM_BUG_ON. * No need to explicitly assign a NULL pointer to engine in legacy mode. * No need to move gen8_make_rpcs up. * Factored out global barrier as prep patch. * Allow to only CAP_SYS_ADMIN if !Gen11. v11: * Remove engine vfunc in favour of local helper.

To lower CPU overhead, future userspace will be switching to pinning iova and avoiding the use of relocs, and only include cmds table entries for IB1 level cmdstream (but not IB2 or state-groups).

2018-12-05drm: Add a new plane property to send damage during plane updateLukasz Spintzyk1-0/+19
FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions on the plane in framebuffer coordinates of the framebuffer attached to the plane. The layout of blob data is simply an array of "struct drm_mode_rect". Unlike plane src coordinates, damage clips are not in 16.16 fixed point. As plane src in framebuffer cannot be negative so are damage clips. In damage clip, x1/y1 are inclusive and x2/y2 are exclusive. This patch also exports the kernel internal drm_rect to userspace as drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient to represent damage for current plane size. Driver which are interested in enabling FB_DAMAGE_CLIPS property for a plane should enable this property using drm_plane_enable_damage_clips. v2: - Input validation on damage clips against framebuffer size. - Doc update, other minor changes.

2018-11-30drm/v3d: Add support for submitting jobs to the TFU.Eric Anholt1-0/+25
The TFU can copy from raster, UIF, and SAND input images to UIF output images, with optional mipmap generation. This will certainly be useful for media EGL image input, but is also useful immediately for mipmap generation without bogging the V3D core down. For now we only run the queue 1 job deep, and don't have any hang recovery (though I don't think we should need it, with TFU). Queuing multiple jobs in the HW will require synchronizing the YUV coefficient regs updates since they don't get FIFOed with the job. v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain why TFU is AUTH, clarify the syncing docs, drop the unused TFU interrupt regs (you're expected to use the hub's), don't take &bo->base for NULL bos. v3: Fix a little whitespace alignment (noticed by checkpatch), rebase on drm_sched_job_cleanup() changes.

In the case where the user didn't request OA reports to be available through the i915 perf stream, we can set the OA buffer to the minimum size to avoid consuming memory which won't be used by the driver. v2: Simplify oa buffer size exponent selection (Chris) Reuse vma size field (Lionel) v3: Restrict size opening parameter to values supported by HW (Chris) v4: Drop out of date comment (Matt) Add debug message when buffer size is rejected (Matt) Signed-off-by: Lionel Landwerlin <[email protected]> Reviewed-by: Matthew Auld <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2018-10-18drm: add syncobj timeline support v9Chunming Zhou1-0/+1
This patch is for VK_KHR_timeline_semaphore extension, semaphore is called syncobj in kernel side: This extension introduces a new type of syncobj that has an integer payload identifying a point in a timeline. Such timeline syncobjs support the following operations: * CPU query - A host operation that allows querying the payload of the timeline syncobj. * CPU wait - A host operation that allows a blocking wait for a timeline syncobj to reach a specified value. * Device wait - A device operation that allows waiting for a timeline syncobj to reach a specified value. * Device signal - A device operation that allows advancing the timeline syncobj to a specified value. v1: Since it's a timeline, that means the front time point(PT) always is signaled before the late PT. a. signal PT design: Signal PT fence N depends on PT[N-1] fence and signal opertion fence, when PT[N] fence is signaled, the timeline will increase to value of PT[N]. b. wait PT design: Wait PT fence is signaled by reaching timeline point value, when timeline is increasing, will compare wait PTs value with new timeline value, if PT value is lower than timeline value, then wait PT will be signaled, otherwise keep in list. syncobj wait operation can wait on any point of timeline, so need a RB tree to order them. And wait PT could ahead of signal PT, we need a sumission fence to perform that. v2: 1. remove unused DRM_SYNCOBJ_CREATE_TYPE_NORMAL. (Christian) 2. move unexposed denitions to .c file. (Daniel Vetter) 3. split up the change to drm_syncobj_find_fence() in a separate patch. (Christian) 4. split up the change to drm_syncobj_replace_fence() in a separate patch. 5. drop the submission_fence implementation and instead use wait_event() for that. (Christian) 6. WARN_ON(point != 0) for NORMAL type syncobj case. (Daniel Vetter) v3: 1. replace normal syncobj with timeline implemenation. (Vetter and Christian) a. normal syncobj signal op will create a signal PT to tail of signal pt list. b. normal syncobj wait op will create a wait pt with last signal point, and this wait PT is only signaled by related signal point PT. 2. many bug fix and clean up 3. stub fence moving is moved to other patch. v4： 1. fix RB tree loop with while(node=rb_first(...)). (Christian) 2. fix syncobj lifecycle. (Christian) 3. only enable_signaling when there is wait_pt. (Christian) 4. fix timeline path issues. 5. write a timeline test in libdrm v5: (Christian) 1. semaphore is called syncobj in kernel side. 2. don't need 'timeline' characters in some function name. 3. keep syncobj cb. v6: (Christian) 1. merge syncobj_timeline to syncobj structure. 2. simplify some check sentences. 3. some misc change. 4. fix CTS failed issue. v7: (Christian) 1. error handling when creating signal pt. 2. remove timeline naming in func. 3. export flags in find_fence. 4. allow reset timeline. v8: 1. use wait_event_interruptible without timeout 2. rename _TYPE_INDIVIDUAL to _TYPE_BINARY v9: 1. rename signal_pt->base to signal_pt->fence_array to avoid misleading 2. improve kerneldoc individual syncobj is tested by ./deqp-vk -n dEQP-VK*semaphore* timeline syncobj is tested by ./amdgpu_test -s 9 Signed-off-by: Chunming Zhou <[email protected]> Signed-off-by: Christian König <[email protected]> Cc: Christian Konig <[email protected]> Cc: Dave Airlie <[email protected]> Cc: Daniel Rakos <[email protected]> Cc: Daniel Vetter <[email protected]> Cc: Bas Nieuwenhuizen <[email protected]> Cc: Jason Ekstrand <[email protected]> Reviewed-by: Christian König <[email protected]> Acked-by: Daniel Vetter <[email protected]> Link: https://patchwork.freedesktop.org/patch/257258/

2018-07-20drm/i915: Only force GGTT coherency w/a on required chipsetsChris Wilson1-0/+22
Not all chipsets have an internal buffer delaying the visibility of writes via the GGTT being visible by other physical paths, but we use a very heavy workaround for all. We only need to apply that workarounds to the chipsets we know suffer from the delay and the resulting coherency issue. Similarly, the same inconsistent coherency fouls up our ABI promise that a write into a mmap_gtt is immediately visible to others. Since the HW has made that a lie, let userspace know when that contract is broken. (Not that userspace would want to use mmap_gtt on those chipsets for other performance reasons...)
