2018-03-08drm/i915: expose rcs topology through query uAPILionel Landwerlin1-0/+62
With the introduction of asymmetric slices in CNL, we cannot rely on the previous SUBSLICE_MASK getparam to tell userspace what subslices are available. Here we introduce a more detailed way of querying the Gen's GPU topology that doesn't aggregate numbers. This is essential for monitoring parts of the GPU with the OA unit, because counters need to be normalized to the number of EUs/subslices/slices. The current aggregated numbers like EU_TOTAL do not gives us sufficient information.

2018-03-08drm/i915: add query uAPILionel Landwerlin1-3/+43
There are a number of information that are readable from hardware registers and that we would like to make accessible to userspace. One particular example is the topology of the execution units (how are execution units grouped in subslices and slices and also which ones have been fused off for die recovery). At the moment the GET_PARAM ioctl covers some basic needs, but generally is only able to return a single value for each defined parameter. This is a bit problematic with topology descriptions which are array/maps of available units. This change introduces a new ioctl that can deal with requests to fill structures of potentially variable lengths. The user is expected fill a query with length fields set at 0 on the first call, the kernel then sets the length fields to the their expected values. A second call to the kernel with length fields at their expected values will trigger a copy of the data to the pointed memory locations. The scope of this uAPI is only to provide information to userspace, not to allow configuration of the device. v2: Simplify dispatcher code iteration (Tvrtko) Tweak uapi drm_i915_query_item structure (Tvrtko) v3: Rename pad fields into flags (Chris) Return error on flags field != 0 (Chris) Only copy length back to userspace in drm_i915_query_item (Chris) v4: Use array of functions instead of switch (Chris) v5: More comments in uapi (Tvrtko) Return query item errors in length field (All) v6: Tweak uapi comments style to match the coding style (Lionel) v7: Add i915_query.h (Joonas) v8: (Lionel) Change the behavior of the item iterator to report invalid queries into the query item rather than stopping the iteration. This enables userspace applications to query newer items on older kernels and only have failure on the items that are not supported. v9: Edit copyright headers (Joonas) v10: Typos & comments in uapi (Joonas) Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Acked-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180306122857.27317-6-lionel.g.landwerlin@intel.com
2018-03-07drm/uapi: Deprecate DRM_MODE_PROP_PENDINGVille Syrjälä1-1/+1
DRM_MODE_PROP_PENDING is not used anywhere (except printed out by libdrm proptest/modetest). This seems to be yet another thing blindly copied from xrandr. Quoting from the protocol spec: "If 'pending' is TRUE, changes made to property values with RRChangeOutputProperty will be saved in the pending property value and be automatically copied to the current value on the next RRSetCrtcConfig request involving the named output. If 'pending' is FALSE, changes are copied immediately." So it was some kind of early idea for atomic property updates.

Deprecate the silly I915_SET_COLORKEY_NONE flag. The obvious way to disable colorkey is to just set flags to 0, which is exactly what the intel ddx has been doing all along. Currently when userspace sets the flags to 0, we end up in a funny state where colorkey is disabled, but various colorkey vs. scaling checks still consider colorkey to be enabled, and thus we don't allow plane scaling to kick in. In case there is some other userspace out there that actually uses this flag (unlikely as this is an i915 specific uapi) we'll keep on accepting it.

Reject any mode with DRM_MODE_FLAG_BCAST. We have no code that even checks for this flag hence it can't possibly do any good. I think this maybe originated from fbdev where it was supposed to indicate PAL/NTSC broadcast timings. I have no idea why those would have to be identified by a flag rather than by just the timings themselves. And then I assume it got copied into xfree86 for fbdevhw, and later on it leaked into the randr protocol and kms uapi. Since kms fbdev emulation never uses the corresponding fbdev flag there should be no sane way for this to come back into kms via userspace either.

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 ...
2018-01-08drm: Add Content Protection propertySean Paul1-0/+4
This patch adds a new optional connector property to allow userspace to enable protection over the content it is displaying. This will typically be implemented by the driver using HDCP. The property is a tri-state with the following values: - OFF: Self explanatory, no content protection - DESIRED: Userspace requests that the driver enable protection - ENABLED: Once the driver has authenticated the link, it sets this value The driver is responsible for downgrading ENABLED to DESIRED if the link becomes unprotected. The driver should also maintain the desiredness of protection across hotplug/dpms/suspend. If this looks familiar, I posted [1] this 3 years ago. We have been using this in ChromeOS across exynos, mediatek, and rockchip over that time. Changes in v2: - Pimp kerneldoc for content_protection_property (Daniel) - Drop sysfs attribute Changes in v3: - None Changes in v4: - Changed kerneldoc to recommend userspace polling (Daniel) - Changed kerneldoc to briefly describe how to attach the property (Daniel) Changes in v5: - checkpatch whitespace noise - Change DRM_MODE_CONTENT_PROTECTION_OFF to DRM_MODE_CONTENT_PROTECTION_UNDESIRED Changes in v6: - None Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Sean Paul <seanpaul@chromium.org> [1] https://lists.freedesktop.org/archives/dri-devel/2014-December/073336.html Link: https://patchwork.freedesktop.org/patch/msgid/20180108195545.218615-4-seanpaul@chromium.org
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.

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. This should stop us from accidentally overwriting it via the GTT (and frees up some precious GTT space).

2017-11-10drm/i915: Define an engine class enum for the uABITvrtko Ursulin1-0/+16
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. To isolate the uABI from any variations between hw generations, we define an abstract class for the engines and internally map onto the hw. v2: Remove MAX from the uABI; keep it internal if we need it, but don't let userspace make the mistake of using it themselves. v3: s/OTHER/INVALID/ The use of OTHER is ill-defined, so remove it from the uABI as any future new type of engine can define a class to suit it. But keep a reserved value for an invalid class, so that we can always unambiguously express when something doesn't belong to the classification.

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: 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.
