drm/i915/selftests: Add tests for GT and engine workaround verification
Two simple selftests which test that both GT and engine workarounds are not lost after either a full GPU reset, or after the per-engine ones. (Including checks that one engine reset is not affecting workarounds not belonging to itself.) v2: * Rebase for series refactoring. * Add spinner for actual engine reset! * Add idle reset test as well. (Chris Wilson) * Share existing global_reset_lock. (Chris Wilson) v3: * intel_engine_verify_workarounds can be static. * API rename. (Chris Wilson) * Move global reset lock out of the loop.

drm/i915: Split i915_gem_timeline into individual timelines
We need to move to a more flexible timeline that doesn't assume one fence context per engine, and so allow for a single timeline to be used across a combination of engines. This means that preallocating a fence context per engine is now a hindrance, and so we want to introduce the singular timeline. From the code perspective, this has the notable advantage of clearing up a lot of mirky semantics and some clumsy pointer chasing. By splitting the timeline up into a single entity rather than an array of per-engine timelines, we can realise the goal of the previous patch of tracking the timeline alongside the ring. v2: Tweak wait_for_idle to stop the compiling thinking that ret may be uninitialised.

drm/i915: Implement dynamic GuC WOPCM offset and size calculation
Hardware may have specific restrictions on GuC WOPCM offset and size. On Gen9, the value of the GuC WOPCM size register needs to be larger than the value of GuC WOPCM offset register + a Gen9 specific offset (144KB) for reserved GuC WOPCM. Fail to enforce such a restriction on GuC WOPCM size will lead to GuC firmware execution failures. On the other hand, with current static GuC WOPCM offset and size values (512KB for both offset and size), the GuC WOPCM size verification will fail on Gen9 even if it can be fixed by lowering the GuC WOPCM offset by calculating its value based on HuC firmware size (which is likely less than 200KB on Gen9), so that we can have a GuC WOPCM size value which is large enough to pass the GuC WOPCM size check. This patch updates the reserved GuC WOPCM size for RC6 context on Gen9 to 24KB to strictly align with the Gen9 GuC WOPCM layout. It also adds support to verify the GuC WOPCM size aganist the Gen9 hardware restrictions. To meet all above requirements, let's provide dynamic partitioning of the WOPCM that will be based on platform specific HuC/GuC firmware sizes. v2: - Removed intel_wopcm_init (Ville/Sagar/Joonas) - Renamed and Moved the intel_wopcm_partition into intel_guc (Sagar) - Removed unnecessary function calls (Joonas) - Init GuC WOPCM partition as soon as firmware fetching is completed v3: - Fixed indentation issues (Chris) - Removed layering violation code (Chris/Michal) - Created separat files for GuC wopcm code (Michal) - Used inline function to avoid code duplication (Michal) v4: - Preset the GuC WOPCM top during early GuC init (Chris) - Fail intel_uc_init_hw() as soon as GuC WOPCM partitioning failed v5: - Moved GuC DMA WOPCM register updating code into intel_wopcm.c - Took care of the locking status before writing to GuC DMA Write-Once registers.

drm/i915: add query uAPI
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)

drm/i915: Rename drm_i915_gem_request to i915_request
We want to de-emphasize the link between the request (dependency, execution and fence tracking) from GEM and so rename the struct from drm_i915_gem_request to i915_request. That is we may implement the GEM user interface on top of requests, but they are an abstraction for tracking execution rather than an implementation detail of GEM. (Since they are not tied to HW, we keep the i915 prefix as opposed to intel.) In short, the spatch: @@ @@ - struct drm_i915_gem_request + struct i915_request A corollary to contracting the type name, we also harmonise on using 'rq' shorthand for local variables where space if of the essence and repetition makes 'request' unwieldy.

drm/i915: Add HDCP framework + base implementation
This patch adds the framework required to add HDCP support to intel connectors. It implements Aksv loading from fuse, and parts 1/2/3 of the HDCP authentication scheme. Note that without shim implementations, this does not actually implement HDCP. That will come in subsequent patches. Changes in v2: - Don't open code wait_fors (Chris) - drm_hdcp.c under MIT license (Daniel) - Move intel_hdcp_disable() call above ddi_disable (Ram) - Fix // comments (I wore a cone of shame for 12 hours to atone) (Daniel) - Justify intel_hdcp_shim with comments (Daniel) - Fixed async locking issues by adding hdcp_mutex (Daniel) - Don't alter connector_state in enable/disable (Daniel) Changes in v3: - Added hdcp_mutex/hdcp_value to make async reasonable - Added hdcp_prop_work to separate link checking & property setting - Added new helper for atomic_check state tracking (Daniel) - Moved enable/disable into atomic_commit with matching helpers - Moved intel_hdcp_check_link out of all locks when called from dp - Bumped up ksv_fifo timeout (noticed failure on one of my dongles) Changes in v4: - Remove SKL_ prefix from most register names (Daniel) - Move enable/disable back to modeset path (Daniel) - s/get_random_long/get_random_u32/ (Daniel) - Remove mode_config.mutex lock in prop_work (Daniel) - Add intel_hdcp_init to handle init of conn components (Daniel) - Actually check return value of attach_property - Check Bksv is valid before trying to authenticate (Ram) Changes in v5: - checkpatch whitespace changes - s/DRM_MODE_CONTENT_PROTECTION_OFF/DRM_MODE_CONTENT_PROTECTION_UNDESIRED/ - Fix ksv list wait timeout (actually wait 5s) - Increase the R0 timeout to 300ms (Ram) Changes in v6: - SPDX license Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Ramalingam C <ramalingm.c@intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20180108195545.218615-6-seanpaul@chromium.org |

drm/i915/guc : Decoupling ADS and logs from submission
The Additional Data Struct (ADS) contains objects that are required by GuC post FW load and are not necessarily submission-only. Even with submission disabled we may require something inside the ADS, so it makes more sense for them to be always created. Similarly, we need to access GuC logs and even if GuC submission is disabled, to debug issues with GuC loading or with whatever we're using GuC for. v2: re-wording commit message (Sagar) Signed-off-by: Sujaritha Sundaresan <sujaritha.sundaresan@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Sagar Arun Kamble <sagar.a.kamble@intel.com> Reviewed-by: Sagar Arun Kamble <sagar.a.kamble@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/1514928025-29659-1-git-send-email-sujaritha.sundaresan@intel.com |

drm/i915/pmu: Expose a PMU interface for perf queries
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.

License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

drm/i915: Replace "cc-option -Wno-foo" with "cc-disable-warning foo"
To quote kbuild/makefiles.txt:
cc-disable-warning checks if gcc supports a given warning and returns
the commandline switch to disable it. This special function is needed,
because gcc 4.4 and later accept any unknown -Wno-* option and only
warn about it if there is another warning in the source file.
This is exactly what we were trying to achieve with cc-option -Wno-foo and
failed miserably.

drm/i915: Add -Wall -Wextra to our build, set warnings to full
Recently W=1 on gcc-7.2 (-Wunused-const-variable) caught a regression that had been lurking for 6 months, so lets try enabling the full set of warnings for CI builds. This means more patches will be rejected early that contain trivial and sometimes not so trivial bugs. However, our code does not yet compile cleanly with W=1, so we have to apply a filter to the set of warnings until we can eliminate the mistakes. It also means that developers will have to be running the full gamut of gcc to ensure that as warnings come and go with gcc updates, we have the CI build prepared. v2: Use fine-grained -Wno overrides. Inside the makefile, we can specify CFLAGS on a per-object level, which allows us to limit the scope of any particular warning override. v3: Place per-file overrides after the main enabling block.

drm/i915: introduce simple gemfs
Not a fully blown gemfs, just our very own tmpfs kernel mount. Doing so
moves us away from the shmemfs shm_mnt, and gives us the much needed
flexibility to do things like set our own mount options, namely huge=
which should allow us to enable the use of transparent-huge-pages for
our shmem backed objects.
v2: various improvements suggested by Joonas
v3: move gemfs instance to i915.mm and simplify now that we have
file_setup_with_mnt
v4: fallback to tmpfs shm_mnt upon failure to setup gemfs
v5: make tmpfs fallback kinder
v5: better gemfs failure message

drm/i915: Use correct path to trace include
The header comment in include/trace/define_trace.h specifies that the TRACE_INCLUDE_PATH needs to be relative to the define_trace.h header rather than the trace file including it.

drm/i915: Split obj->cache_coherent to track r/w
Another month, another story in the cache coherency saga. This time, we
come to the realisation that i915_gem_object_is_coherent() has been
reporting whether we can read from the target without requiring a cache
invalidate; but we were using it in places for testing whether we could
write into the object without requiring a cache flush. So split the
tracking into two, one to decide before reads, one after writes.

drm/i915: Squash repeated awaits on the same fence
Track the latest fence waited upon on each context, and only add a new asynchronous wait if the new fence is more recent than the recorded fence for that context. This requires us to filter out unordered timelines, which are noted by DMA_FENCE_NO_CONTEXT. However, in the absence of a universal identifier, we have to use our own i915->mm.unordered_timeline token. v2: Throw around the debug crutches v3: Inline the likely case of the pre-allocation cache being full. v4: Drop the pre-allocation support, we can lose the most recent fence in case of allocation failure -- it just means we may emit more awaits than strictly necessary but will not break. v5: Trim allocation size for leaf nodes, they only need an array of u32 not pointers. v6: Create mock_timeline to tidy selftest writing v7: s/intel_timeline_sync_get/intel_timeline_sync_is_later/ (Tvrtko) v8: Prune the stale sync points when we idle. v9: Include a small benchmark in the kselftests v10: Separate the idr implementation into its own compartment.
