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: Warn against variable length arrays

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/uc: Make GuC/HuC fw fetch and loading functions/file structure symmetric
GuC load function is named intel_guc_fw_upload() and HuC load function is
named intel_huc_init_hw(). Make them consistent intel_*_fw_upload. Also
move HuC fw loading functions and declarations to separate files
intel_huc_fw.c|h like GuC.
While at this, do below changes
1. Update kernel-doc comment for intel_*_fw_upload() functions
2. s/huc_ucode_xfer/huc_fw_xfer
3. Introduce intel_huc_fw_init_early()
v2: Changed patch to update HuC functions instead of changing
guc_fw_upload and update file structure. (Michal Wajdeczko)
v3: Added SPDX License identifier to huc_fw.c|h. (Michal Wajdeczko)

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. For globals and struct members, 'request' is still much preferred for its clarity.

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.

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. Most instances get that wrong and work around it by adding the $(src) directory to the include path. While this works, it is preferable to refer to the correct path to the trace file in the first place and avoid any workaround.

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.

drm/i915: Perform object clflushing asynchronously
Flushing the cachelines for an object is slow, can be as much as 100ms for a large framebuffer. We currently do this under the struct_mutex BKL on execution or on pageflip. But now with the ability to add fences to obj->resv for both flips and execbuf (and we naturally wait on the fence before CPU access), we can move the clflush operation to a workqueue and signal a fence for completion, thereby doing the work asynchronously and not blocking the driver or its clients. v2: Introduce i915_gem_clflush.h and use a new name, split out some extras into separate patches.

drm/i915: Provide a hook for selftests
Some pieces of code are independent of hardware but are very tricky to exercise through the normal userspace ABI or via debugfs hooks. Being able to create mock unit tests and execute them through CI is vital. Start by adding a central point where we can execute unit tests and a parameter to enable them. This is disabled by default as the expectation is that these tests will occasionally explode. To facilitate integration with igt, any parameter beginning with i915.igt__ is interpreted as a subtest executable independently via igt/drv_selftest. Two classes of selftests are recognised: mock unit tests and integration tests. Mock unit tests are run as soon as the module is loaded, before the device is probed. At that point there is no driver instantiated and all hw interactions must be "mocked". This is very useful for writing universal tests to exercise code not typically run on a broad range of architectures. Alternatively, you can hook into the live selftests and run when the device has been instantiated - hw interactions are real. v2: Add a macro for compiling conditional code for mock objects inside real objects. v3: Differentiate between mock unit tests and late integration test. v4: List the tests in natural order, use igt to sort after modparam. v5: s/late/live/ v6: s/unsigned long/unsigned int/ v7: Use igt_ prefixes for long helpers. v8: Deobfuscate macros overriding functions, stop using -I$(src) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170213171558.20942-1-chris@chris-wilson.co.uk |

v5: rebased. Changed the year in the copyright message to reflect
the right year.Correct the comments,remove the unwanted WARN message,
replace drm_gem_object_unreference() with i915_gem_object_put().Make the
prototypes in intel_huc.h non-extern.
v6: rebased. Update the file construction done by HuC. It is similar to
GuC.Adopted the approach used in-
https://patchwork.freedesktop.org/patch/104355/ <Tvrtko Ursulin>
v7: Change dev to dev_priv in macro definition.
Corrected comments.
v8: rebased on top of drm-tip. Updated functions intel_huc_load(),
intel_huc_init() and intel_uc_fw_fetch() to accept dev_priv instead of
dev. Moved contents of intel_huc.h to intel_uc.h.
v9: change SKL_FW_ to SKL_HUC_FW_. Add intel_ prefix to guc_wopcm_size().
Remove unwanted checks in intel_uc.h. Rename huc_fw in struct intel_huc to
simply fw to avoid redundency.
v10: rebased. Correct comments. Make intel_huc_fini() accept dev_priv
instead of dev like intel_huc_init() and intel_huc_load().Move definition
to i915_guc_reg.h from intel_uc.h. Clean DMA_CTRL bits after HuC DMA
transfer in huc_ucode_xfer() instead of guc_ucode_xfer(). Add suitable
WARNs to give extra info.
v11: rebased. Add proper bias for HuC and make sure there are
asserts on failure by using guc_ggtt_offset_vma(). Introduce
intel_huc.c and remove intel_huc_loader.c since it has functions that
do more than just loading.Correct year in copyright.
v12: remove invalidates that are not required anymore.

drm/i915/guc: Move GuC log related functions into dedicated file

drm/i915: Add i915 perf infrastructure
Adds base i915 perf infrastructure for Gen performance metrics.
This adds a DRM_IOCTL_I915_PERF_OPEN ioctl that takes an array of uint64
properties to configure a stream of metrics and returns a new fd usable
with standard VFS system calls including read() to read typed and sized
records; ioctl() to enable or disable capture and poll() to wait for
data.
A stream is opened something like:
uint64_t properties[] = {
/* Single context sampling */
DRM_I915_PERF_PROP_CTX_HANDLE, ctx_handle,
/* Include OA reports in samples */
DRM_I915_PERF_PROP_SAMPLE_OA, true,
/* OA unit configuration */
DRM_I915_PERF_PROP_OA_METRICS_SET, metrics_set_id,
DRM_I915_PERF_PROP_OA_FORMAT, report_format,
DRM_I915_PERF_PROP_OA_EXPONENT, period_exponent,
};
struct drm_i915_perf_open_param parm = {
.flags = I915_PERF_FLAG_FD_CLOEXEC |
I915_PERF_FLAG_FD_NONBLOCK |
I915_PERF_FLAG_DISABLED,
.properties_ptr = (uint64_t)properties,
.num_properties = sizeof(properties) / 16,
};
int fd = drmIoctl(drm_fd, DRM_IOCTL_I915_PERF_OPEN, ¶m);
Records read all start with a common { type, size } header with
DRM_I915_PERF_RECORD_SAMPLE being of most interest. Sample records
contain an extensible number of fields and it's the
DRM_I915_PERF_PROP_SAMPLE_xyz properties given when opening that
determine what's included in every sample.
No specific streams are supported yet so any attempt to open a stream
will return an error.
v2:
use i915_gem_context_get() - Chris Wilson
v3:
update read() interface to avoid passing state struct - Chris Wilson
fix some rebase fallout, with i915-perf init/deinit
v4:
s/DRM_IORW/DRM_IOW/ - Emil Velikov

drm/i915: Split out i915_vma.c
As a side product, had to split two other files;
- i915_gem_fence_reg.h
- i915_gem_object.h (only parts that needed immediate untanglement)
I tried to move code in as big chunks as possible, to make review
easier. i915_vma_compare was moved to a header temporarily.
v2:
- Use i915_gem_fence_reg.{c,h}
v3:
- Rebased
v4:
- Fix building when DEBUG_GEM is enabled by reordering a bit.

drm/i915: Combine seqno + tracking into a global timeline struct
Our timelines are more than just a seqno. They also provide an ordered list of requests to be executed. Due to the restriction of handling individual address spaces, we are limited to a timeline per address space but we use a fence context per engine within. Our first step to introducing independent timelines per context (i.e. to allow each context to have a queue of requests to execute that have a defined set of dependencies on other requests) is to provide a timeline abstraction for the global execution queue.
