git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.16-rc1 The bulk of these changes are preparation work and addition of support for Tegra186. Currently only HDMI output (the primary output on Jetson TX2) is supported, but the hardware is also capable of doing DSI and DisplayPort. Tegra DRM now also uses the atomic commit helpers instead of the open- coded variant that was only doing half its job. As a bit of a byproduct of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos property support. Along the way there are also a few patches to clean up a few things and fix minor issues. * tag 'drm/tegra/for-4.16-rc1-fixes' of git://anongit.freedesktop.org/tegra/linux: (51 commits) drm/tegra: dc: Properly cleanup overlay planes drm/tegra: dc: Fix possible_crtcs mask for planes drm/tegra: dc: Restore YUV overlay support drm/tegra: dc: Implement legacy blending drm/tegra: Correct timeout in tegra_syncpt_wait drm/tegra: gem: Correct iommu_map_sg() error checking drm/tegra: dc: Link DC1 to DC0 on Tegra20 drm/tegra: Fix non-debugfs builds drm/tegra: dpaux: Keep reset defaults for hybrid pad parameters drm/tegra: Mark Tegra186 display hub PM functions __maybe_unused drm/tegra: Use IOMMU groups gpu: host1x: Use IOMMU groups drm/tegra: Implement zpos property drm/tegra: dc: Remove redundant spinlock drm/tegra: dc: Use direct offset to plane registers drm/tegra: dc: Support more formats drm/tegra: fb: Force alpha formats drm/tegra: dpaux: Add Tegra186 support drm/tegra: dpaux: Implement runtime PM drm/tegra: sor: Support HDMI 2.0 modes ...
2018-01-02drm/exynos: ipp: Remove Exynos DRM IPP subsystemMarek Szyprowski1-191/+1
Exynos DRM IPP subsystem is in fact non-functional and frankly speaking dead-code. This patch clearly marks that Exynos DRM IPP subsystem is broken and never really functional. It will be replaced by a completely rewritten API. Exynos DRM IPP user-space API can be obsoleted for the following reasons: 1. Exynos DRM IPP user-space API can be optional in Exynos DRM, so userspace should not rely that it is always available and should have a software fallback in case it is not there. 2. The only mode which was initially semi-working was memory-to-memory image processing. The remaining modes (LCD-"writeback" and "output") were never operational due to missing code (both in mainline and even vendor kernels). 3. Exynos DRM IPP mainline user-space API compatibility for memory-to-memory got broken very early by commit 083500baefd5 ("drm: remove DRM_FORMAT_NV12MT", which removed the support for tiled formats, the main feature which made this API somehow useful on Exynos platforms (video codec that time produced only tiled frames, to implement xvideo or any other video overlay, one has to de-tile them for proper display). 4. Broken drivers. Especially once support for IOMMU has been added, it revealed that drivers don't configure DMA operations properly and in many cases operate outside the provided buffers trashing memory around. 5. Need for external patches. Although IPP user-space API has been used in some vendor kernels, but in such cases there were additional patches applied (like reverting mentioned 083500baefd5 patch) what means that those userspace apps which might use it, still won't work with the mainline kernel version. We don't have time machines, so we cannot change it, but Exynos DRM IPP extension should never have been merged to mainline in that form. Exynos IPP subsystem and user-space API will be rewritten, so remove current IPP core code and mark existing drivers as BROKEN.

2017-12-13drm/tegra: Sanitize format modifiersThierry Reding1-17/+19
The existing format modifier definitions were merged prematurely, and recent work has unveiled that the definitions are suboptimal in several ways: - The format specifiers, except for one, are not Tegra specific, but the names don't reflect that. - The number space is split into two, reserving 32 bits for some "parameter" which most of the modifiers are not going to have. - Symbolic names for the modifiers are not using the standard DRM_FORMAT_MOD_* prefix, which makes them awkward to use. - The vendor prefix NV is somewhat ambiguous. Fortunately, nobody's started using these modifiers, so we can still fix the above issues. Do so by using the standard prefix. Also, remove TEGRA from the name of those modifiers that exist on NVIDIA GPUs as well. In case of the block linear modifiers, make the "parameter" smaller (4 bits, though only 6 values are valid) and don't let that leak into any of the other modifiers. Finally, also use the more canonical NVIDIA instead of the ambiguous NV prefix. Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Thierry Reding <treding@nvidia.com>

2017-11-24drm/i915/pmu: Aggregate all RC6 states into one counterTvrtko Ursulin1-5/+1
Chris has discovered that RC6, RC6p and RC6pp counters are mutually exclusive, and even that on some SNB SKUs you get RC6p increasing, and on the others RC6. Furthermore RC6p and RC6pp were only present starting from GEN6 until, GEN7, not including Haswell. All this combined makes it questionable whether we need to reserve new ABI for these counters. One idea was to just combine them all under the RC6 counter to simplify things for userspace. So that is what this patch does.

2017-11-22drm/i915/pmu: Expose a PMU interface for perf queriesTvrtko Ursulin1-0/+39
From: Chris Wilson <chris@chris-wilson.co.uk> From: Tvrtko Ursulin <tvrtko.ursulin@intel.com> From: Dmitry Rogozhkin <dmitry.v.rogozhkin@intel.com> The first goal is to be able to measure GPU (and invidual ring) busyness without having to poll registers from userspace. (Which not only incurs holding the forcewake lock indefinitely, perturbing the system, but also runs the risk of hanging the machine.) As an alternative we can use the perf event counter interface to sample the ring registers periodically and send those results to userspace. Functionality we are exporting to userspace is via the existing perf PMU API and can be exercised via the existing tools. For example: perf stat -a -e i915/rcs0-busy/ -I 1000 Will print the render engine busynnes once per second. All the performance counters can be enumerated (perf list) and have their unit of measure correctly reported in sysfs. v1-v2 (Chris Wilson): v2: Use a common timer for the ring sampling. v3: (Tvrtko Ursulin) * Decouple uAPI from i915 engine ids. * Complete uAPI defines. * Refactor some code to helpers for clarity. * Skip sampling disabled engines. * Expose counters in sysfs. * Pass in fake regs to avoid null ptr deref in perf core. * Convert to class/instance uAPI. * Use shared driver code for rc6 residency, power and frequency. v4: (Dmitry Rogozhkin) * Register PMU with .task_ctx_nr=perf_invalid_context * Expose cpumask for the PMU with the single CPU in the mask * Properly support pmu->stop(): it should call pmu->read() * Properly support pmu->del(): it should call stop(event, PERF_EF_UPDATE) * Introduce refcounting of event subscriptions. * Make pmu.busy_stats a refcounter to avoid busy stats going away with some deleted event. * Expose cpumask for i915 PMU to avoid multiple events creation of the same type followed by counter aggregation by perf-stat. * Track CPUs getting online/offline to migrate perf context. If (likely) cpumask will initially set CPU0, CONFIG_BOOTPARAM_HOTPLUG_CPU0 will be needed to see effect of CPU status tracking. * End result is that only global events are supported and perf stat works correctly. * Deny perf driver level sampling - it is prohibited for uncore PMU. v5: (Tvrtko Ursulin) * Don't hardcode number of engine samplers. * Rewrite event ref-counting for correctness and simplicity. * Store initial counter value when starting already enabled events to correctly report values to all listeners. * Fix RC6 residency readout. * Comments, GPL header. v6: * Add missing entry to v4 changelog. * Fix accounting in CPU hotplug case by copying the approach from arch/x86/events/intel/cstate.c. (Dmitry Rogozhkin) v7: * Log failure message only on failure. * Remove CPU hotplug notification state on unregister. v8: * Fix error unwind on failed registration. * Checkpatch cleanup. v9: * Drop the energy metric, it is available via intel_rapl_perf. (Ville Syrjälä) * Use HAS_RC6(p). (Chris Wilson) * Handle unsupported non-engine events. (Dmitry Rogozhkin) * Rebase for intel_rc6_residency_ns needing caller managed runtime pm. * Drop HAS_RC6 checks from the read callback since creating those events will be rejected at init time already. * Add counter units to sysfs so perf stat output is nicer. * Cleanup the attribute tables for brevity and readability. v10: * Fixed queued accounting. v11: * Move intel_engine_lookup_user to intel_engine_cs.c * Commit update. (Joonas Lahtinen) v12: * More accurate sampling. (Chris Wilson) * Store and report frequency in MHz for better usability from perf stat. * Removed metrics: queued, interrupts, rc6 counters. * Sample engine busyness based on seqno difference only for less MMIO (and forcewake) on all platforms. (Chris Wilson) v13: * Comment spelling, use mul_u32_u32 to work around potential GCC issue and somne code alignment changes. (Chris Wilson) v14: * Rebase. v15: * Rebase for RPS refactoring. v16: * Use the dynamic slot in the CPU hotplug state machine so that we are free to setup our state as multi-instance. Previously we were re-using the CPUHP_AP_PERF_X86_UNCORE_ONLINE slot which is neither used as multi-instance, nor owned by our driver to start with. * Register the CPU hotplug handlers after the PMU, otherwise the callback will get called before the PMU is initialized which can end up in perf_pmu_migrate_context with an un-initialized base. * Added workaround for a probable bug in cpuhp core. v17: * Remove workaround for the cpuhp bug. v18: * Rebase for drm_i915_gem_engine_class getting upstream before us. v19: * Rebase.

2017-11-10drm/i915: Record the default hw state after reset upon loadChris Wilson1-0/+15
Take a copy of the HW state after a reset upon module loading by executing a context switch from a blank context to the kernel context, thus saving the default hw state over the blank context image. We can then use the default hw state to initialise any future context, ensuring that each starts with the default view of hw state. v2: Unmap our default state from the GTT after stealing it from the context.

We want to be able to report back to userspace details about an engine's class, and in return for userspace to be able to request actions regarding certain classes of engines.

2017-11-02License cleanup: add SPDX license identifier to uapi header files with a licenseGreg Kroah-Hartman4-0/+4
Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

license Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". otherwise syscall usage would not be possible.

2017-10-28drm/msm: Add a parameter query for the number of ringbuffersJordan Crouse1-0/+1

2017-10-28drm/msm: Support multiple ringbuffersJordan Crouse1-0/+1
Add the infrastructure to support the idea of multiple ringbuffers. Assign each ringbuffer an id and use that as an index for the various ring specific operations. The biggest delta is to support legacy fences. Each fence gets its own sequence number but the legacy functions expect to use a unique integer. To handle this we return a unique identifier for each submission but map it to a specific ring/sequence under the covers. Newer users use a dma_fence pointer anyway so they don't care about the actual sequence ID or ring. The actual mechanics for multiple ringbuffers are very target specific so this code just allows for the possibility but still only defines one ringbuffer for each target family.

2017-10-28drm/msm: Add per-instance submit queuesJordan Crouse1-0/+22
Currently the behavior of a command stream is provided by the user application during submission and the application is expected to internally maintain the settings for each 'context' or 'rendering queue' and specify the correct ones. This works okay for simple cases but as applications become more complex we will want to set context specific flags and do various permission checks to allow certain contexts to enable additional privileges. Add kernel-side submit queues to be analogous to 'contexts' or 'rendering queues' on the application side. Each file descriptor instance will maintain its own list of queues. Queues cannot be shared between file descriptors. For backwards compatibility context id '0' is defined as a default context specifying no priority and no special flags. This is intended to be the usual configuration for 99% of applications so that a garden variety application can function correctly without creating a queue. Only those applications requiring the specific benefit of different queues need create one. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2017-10-25drm: Add four ioctls for managing drm mode object leases [v7]Keith Packard2-0/+71
drm_mode_create_lease Creates a lease for a list of drm mode objects, returning an fd for the new drm_master and a 64-bit identifier for the lessee drm_mode_list_lesees List the identifiers of the lessees for a master file drm_mode_get_lease List the leased objects for a master file drm_mode_revoke_lease Erase the set of objects managed by a lease. This should suffice to at least create and query leases. Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>: * query ioctls only query the master associated with the provided file. * 'mask_lease' value has been removed * change ioctl has been removed. Changes for v3 suggested in part by Dave Airlie <airlied@gmail.com> * Add revoke ioctl. Changes for v4 suggested by Dave Airlie <airlied@gmail.com> * Expand on the comment about the magic use of &drm_lease_idr_object * Pad lease ioctl structures to align on 64-bit boundaries Changes for v5 suggested by Dave Airlie <airlied@gmail.com> * Check for non-negative object_id in create_lease to avoid debug output from the kernel. Changes for v6 provided by Dave Airlie <airlied@gmail.com> * For non-universal planes add primary/cursor planes to lease If we aren't exposing universal planes to this userspace client, and it requests a lease on a crtc, we should implicitly export the primary and cursor planes for the crtc. If the lessee doesn't request universal planes, it will just see the crtc, but if it does request them it will then see the plane objects as well. This also moves the object look ups earlier as a side effect, so we'd exit the ioctl quicker for non-existant objects. * Restrict leases to crtc/connector/planes. This only allows leasing for objects we wish to allow. Changes for v7 provided by Dave Airlie <airlied@gmail.com> * Check pad args are 0 * Check create flags and object count are valid. * Check return from fd allocation * Refactor lease idr setup and add some simple validation * Use idr_mutex uniformly (Keith) Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

This ioctl will allow us to purge inactive userspace buffers when the system is running out of contiguous memory. For now, the purge logic is rather dumb in that it does not try to release only the amount of BO needed to meet the last CMA alloc request but instead purges all objects placed in the purgeable pool as soon as we experience a CMA allocation failure. Note that the in-kernel BO cache is always purged before the purgeable cache because those objects are known to be unused while objects marked as purgeable by a userspace application/library might have to be restored when they are marked back as unpurgeable, which can be expensive.

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 <christian.gmeiner@gmail.com> Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
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 <andresx7@gmail.com> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

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 <emil.l.velikov@gmail.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Andres Rodriguez <andresx7@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2017-10-09drm/amdgpu: introduce AMDGPU_GEM_CREATE_EXPLICIT_SYNC v2Andres Rodriguez1-0/+2
Introduce a flag to signal that access to a BO will be synchronized through an external mechanism. Currently all buffers shared between contexts are subject to implicit synchronization. However, this is only required for protocols that currently don't support an explicit synchronization mechanism (DRI2/3). This patch introduces the AMDGPU_GEM_CREATE_EXPLICIT_SYNC, so that users can specify when it is safe to disable implicit sync. v2: only disable explicit sync in amdgpu_cs_ioctl Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Andres Rodriguez <andresx7@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

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.
