* intel-gpu-tools. The value supplied with the event is always 1.

* I915_ERROR_UEVENT - Generated upon error detection, currently only via
* hangcheck. The error detection event is a good indicator of when things
* began to go badly. The value supplied with the event is a 1 upon error
* detection, and a 0 upon reset completion, signifying no more error
* exists. NOTE: Disabling hangcheck or reset via module parameter will
* cause the related events to not be seen.
*
* I915_RESET_UEVENT - Event is generated just before an attempt to reset the
* GPU. The value supplied with the event is always 1. NOTE: Disable
* reset via module parameter will cause this event to not be seen.

*
* Many interfaces need to grow over time. In most cases we can simply
* extend the struct and have userspace pass in more data. Another option,
* as demonstrated by Vulkan's approach to providing extensions for forward
* and backward compatibility, is to use a list of optional structs to
* provide those extra details.
*
* The key advantage to using an extension chain is that it allows us to
* redefine the interface more easily than an ever growing struct of
* increasing complexity, and for large parts of that interface to be
* entirely optional. The downside is more pointer chasing; chasing across
* the __user boundary with pointers encapsulated inside u64.
*
* Example chaining:
*
* .. code-block:: C
*
* struct i915_user_extension ext3 {
* .next_extension = 0, // end
* .name = ...,
* };
* struct i915_user_extension ext2 {
* .next_extension = (uintptr_t)&ext3,
* .name = ...,
* };
* struct i915_user_extension ext1 {
* .next_extension = (uintptr_t)&ext2,
* .name = ...,
* };
*
* Typically the struct i915_user_extension would be embedded in some uAPI
* struct, and in this case we would feed it the head of the chain(i.e ext1),
* which would then apply all of the above extensions.

DRM_I915_PERF_* calls and a new I915_PARAM_HAS_EXEC_FENCE_ARRAY ABI for the Intel driver. - tools/include/uapi/linux/bpf.h: New bpf_sock fields (::mark and ::priority), new XDP_REDIRECT action, new kvm_ppc_smmu_info fields (::data_keys, instr_keys) Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Milian Wolff <milian.wolff@kdab.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Taeung Song <treeze.taeung@gmail.com> Cc: Wang Nan <wangnan0@huawei.com> Cc: Yao Jin <yao.jin@linux.intel.com> Link: http://lkml.kernel.org/r/20170913073823.lxmi4c7ejqlfabjx@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

DRM_I915_PERF_* calls and a new I915_PARAM_HAS_EXEC_FENCE_ARRAY ABI for the Intel driver. - tools/include/uapi/linux/bpf.h: New bpf_sock fields (::mark and ::priority), new XDP_REDIRECT action, new kvm_ppc_smmu_info fields (::data_keys, instr_keys) Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Milian Wolff <milian.wolff@kdab.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Taeung Song <treeze.taeung@gmail.com> Cc: Wang Nan <wangnan0@huawei.com> Cc: Yao Jin <yao.jin@linux.intel.com> Link: http://lkml.kernel.org/r/20170913073823.lxmi4c7ejqlfabjx@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

* struct drm_i915_gem_set_domain - Adjust the objects write or read domain, in
* preparation for accessing the pages via some CPU domain.
*
* Specifying a new write or read domain will flush the object out of the
* previous domain(if required), before then updating the objects domain
* tracking with the new domain.
*
* Note this might involve waiting for the object first if it is still active on
* the GPU.
*
* Supported values for @read_domains and @write_domain:
*
* - I915_GEM_DOMAIN_WC: Uncached write-combined domain
* - I915_GEM_DOMAIN_CPU: CPU cache domain
* - I915_GEM_DOMAIN_GTT: Mappable aperture domain
*
* All other domains are rejected.
*
* Note that for discrete, starting from DG1, this is no longer supported, and
* is instead rejected. On such platforms the CPU domain is effectively static,
* where we also only support a single &drm_i915_gem_mmap_offset cache mode,
* which can't be set explicitly and instead depends on the object placements,
* as per the below.
*
* Implicit caching rules, starting from DG1:
*
* - If any of the object placements (see &drm_i915_gem_create_ext_memory_regions)
* contain I915_MEMORY_CLASS_DEVICE then the object will be allocated and
* mapped as write-combined only.
*
* - Everything else is always allocated and mapped as write-back, with the
* guarantee that everything is also coherent with the GPU.
*
* Note that this is likely to change in the future again, where we might need
* more flexibility on future devices, so making this all explicit as part of a
* new &drm_i915_gem_create_ext extension is probable.

* struct drm_i915_gem_caching - Set or get the caching for given object

*
* Allow userspace to control the GTT caching bits for a given object when the
* object is later mapped through the ppGTT(or GGTT on older platforms lacking
* ppGTT support, or if the object is used for scanout). Note that this might
* require unbinding the object from the GTT first, if its current caching value
* doesn't match.
*
* Note that this all changes on discrete platforms, starting from DG1, the
* set/get caching is no longer supported, and is now rejected. Instead the CPU
* caching attributes(WB vs WC) will become an immutable creation time property
* for the object, along with the GTT caching level. For now we don't expose any
* new uAPI for this, instead on DG1 this is all implicit, although this largely
* shouldn't matter since DG1 is coherent by default(without any way of
* controlling it).
*
* Implicit caching rules, starting from DG1:
*
* - If any of the object placements (see &drm_i915_gem_create_ext_memory_regions)
* contain I915_MEMORY_CLASS_DEVICE then the object will be allocated and
* mapped as write-combined only.
*
* - Everything else is always allocated and mapped as write-back, with the
* guarantee that everything is also coherent with the GPU.
*
* Note that this is likely to change in the future again, where we might need
* more flexibility on future devices, so making this all explicit as part of a
* new &drm_i915_gem_create_ext extension is probable.
*
* Side note: Part of the reason for this is that changing the at-allocation-time CPU
* caching attributes for the pages might be required(and is expensive) if we
* need to then CPU map the pages later with different caching attributes. This
* inconsistent caching behaviour, while supported on x86, is not universally
* supported on other architectures. So for simplicity we opt for setting
* everything at creation time, whilst also making it immutable, on discrete
* platforms.

/**
* DOC: Virtual Engine uAPI
*
* Virtual engine is a concept where userspace is able to configure a set of
* physical engines, submit a batch buffer, and let the driver execute it on any
* engine from the set as it sees fit.
*
* This is primarily useful on parts which have multiple instances of a same
* class engine, like for example GT3+ Skylake parts with their two VCS engines.
*
* For instance userspace can enumerate all engines of a certain class using the
* previously described `Engine Discovery uAPI`_. After that userspace can
* create a GEM context with a placeholder slot for the virtual engine (using
* `I915_ENGINE_CLASS_INVALID` and `I915_ENGINE_CLASS_INVALID_NONE` for class
* and instance respectively) and finally using the
* `I915_CONTEXT_ENGINES_EXT_LOAD_BALANCE` extension place a virtual engine in
* the same reserved slot.
*
* Example of creating a virtual engine and submitting a batch buffer to it:
*
* .. code-block:: C
*
* I915_DEFINE_CONTEXT_ENGINES_LOAD_BALANCE(virtual, 2) = {
* .base.name = I915_CONTEXT_ENGINES_EXT_LOAD_BALANCE,
* .engine_index = 0, // Place this virtual engine into engine map slot 0
* .num_siblings = 2,
* .engines = { { I915_ENGINE_CLASS_VIDEO, 0 },
* { I915_ENGINE_CLASS_VIDEO, 1 }, },
* };
* I915_DEFINE_CONTEXT_PARAM_ENGINES(engines, 1) = {
* .engines = { { I915_ENGINE_CLASS_INVALID,
* I915_ENGINE_CLASS_INVALID_NONE } },
* .extensions = to_user_pointer(&virtual), // Chains after load_balance extension
* };
* struct drm_i915_gem_context_create_ext_setparam p_engines = {
* .base = {
* .name = I915_CONTEXT_CREATE_EXT_SETPARAM,
* },
* .param = {
* .param = I915_CONTEXT_PARAM_ENGINES,
* .value = to_user_pointer(&engines),
* .size = sizeof(engines),
* },
* };
* struct drm_i915_gem_context_create_ext create = {
* .flags = I915_CONTEXT_CREATE_FLAGS_USE_EXTENSIONS,
* .extensions = to_user_pointer(&p_engines);
* };
*
* ctx_id = gem_context_create_ext(drm_fd, &create);
*
* // Now we have created a GEM context with its engine map containing a
* // single virtual engine. Submissions to this slot can go either to
* // vcs0 or vcs1, depending on the load balancing algorithm used inside
* // the driver. The load balancing is dynamic from one batch buffer to
* // another and transparent to userspace.
*
* ...
* execbuf.rsvd1 = ctx_id;
* execbuf.flags = 0; // Submits to index 0 which is the virtual engine
* gem_execbuf(drm_fd, &execbuf);

/**
* struct i915_context_engines_parallel_submit - Configure engine for
* parallel submission.
*
* Setup a slot in the context engine map to allow multiple BBs to be submitted
* in a single execbuf IOCTL. Those BBs will then be scheduled to run on the GPU
* in parallel. Multiple hardware contexts are created internally in the i915 to
* run these BBs. Once a slot is configured for N BBs only N BBs can be
* submitted in each execbuf IOCTL and this is implicit behavior e.g. The user
* doesn't tell the execbuf IOCTL there are N BBs, the execbuf IOCTL knows how
* many BBs there are based on the slot's configuration. The N BBs are the last
* N buffer objects or first N if I915_EXEC_BATCH_FIRST is set.
*
* The default placement behavior is to create implicit bonds between each
* context if each context maps to more than 1 physical engine (e.g. context is
* a virtual engine). Also we only allow contexts of same engine class and these
* contexts must be in logically contiguous order. Examples of the placement
* behavior are described below. Lastly, the default is to not allow BBs to be
* preempted mid-batch. Rather insert coordinated preemption points on all
* hardware contexts between each set of BBs. Flags could be added in the future
* to change both of these default behaviors.
*
* Returns -EINVAL if hardware context placement configuration is invalid or if
* the placement configuration isn't supported on the platform / submission
* interface.
* Returns -ENODEV if extension isn't supported on the platform / submission
* interface.
*
* .. code-block:: none
*
* Examples syntax:
* CS[X] = generic engine of same class, logical instance X
* INVALID = I915_ENGINE_CLASS_INVALID, I915_ENGINE_CLASS_INVALID_NONE
*
* Example 1 pseudo code:
* set_engines(INVALID)
* set_parallel(engine_index=0, width=2, num_siblings=1,
* engines=CS[0],CS[1])
*
* Results in the following valid placement:
* CS[0], CS[1]
*
* Example 2 pseudo code:
* set_engines(INVALID)
* set_parallel(engine_index=0, width=2, num_siblings=2,
* engines=CS[0],CS[2],CS[1],CS[3])
*
* Results in the following valid placements:
* CS[0], CS[1]
* CS[2], CS[3]
*
* This can be thought of as two virtual engines, each containing two
* engines thereby making a 2D array. However, there are bonds tying the
* entries together and placing restrictions on how they can be scheduled.
* Specifically, the scheduler can choose only vertical columns from the 2D
* array. That is, CS[0] is bonded to CS[1] and CS[2] to CS[3]. So if the
* scheduler wants to submit to CS[0], it must also choose CS[1] and vice
* versa. Same for CS[2] requires also using CS[3].
* VE[0] = CS[0], CS[2]
* VE[1] = CS[1], CS[3]
*
* Example 3 pseudo code:
* set_engines(INVALID)
* set_parallel(engine_index=0, width=2, num_siblings=2,
* engines=CS[0],CS[1],CS[1],CS[3])

/**
* DOC: Context Engine Map uAPI
*
* Context engine map is a new way of addressing engines when submitting batch-
* buffers, replacing the existing way of using identifiers like `I915_EXEC_BLT`
* inside the flags field of `struct drm_i915_gem_execbuffer2`.
*
* To use it created GEM contexts need to be configured with a list of engines
* the user is intending to submit to. This is accomplished using the
* `I915_CONTEXT_PARAM_ENGINES` parameter and `struct
* i915_context_param_engines`.
*
* For such contexts the `I915_EXEC_RING_MASK` field becomes an index into the
* configured map.
*
* Example of creating such context and submitting against it:
*
* .. code-block:: C

* the &drm_i915_query_item.length should still be the same as what the

* Note that for some query items it can make sense for userspace to just pass

/**
* DOC: Engine Discovery uAPI
*
* Engine discovery uAPI is a way of enumerating physical engines present in a
* GPU associated with an open i915 DRM file descriptor. This supersedes the old
* way of using `DRM_IOCTL_I915_GETPARAM` and engine identifiers like
* `I915_PARAM_HAS_BLT`.
*
* The need for this interface came starting with Icelake and newer GPUs, which
* started to establish a pattern of having multiple engines of a same class,
* where not all instances were always completely functionally equivalent.
*
* Entry point for this uapi is `DRM_IOCTL_I915_QUERY` with the
* `DRM_I915_QUERY_ENGINE_INFO` as the queried item id.
*
* Example for getting the list of engines:
*
* .. code-block:: C
*
* struct drm_i915_query_engine_info *info;
* struct drm_i915_query_item item = {
* .query_id = DRM_I915_QUERY_ENGINE_INFO;
* };
* struct drm_i915_query query = {
* .num_items = 1,

* page sizes for such memory. The kernel will already ensure that all
* I915_MEMORY_CLASS_DEVICE memory is allocated using 64K or larger page
* sizes underneath.
*
* Note that the returned size here will always reflect any required
* rounding up done by the kernel, i.e 4K will now become 64K on devices
* such as DG2.
*
* Special DG2 GTT address alignment requirement:
*
* The GTT alignment will also need to be at least 2M for such objects.
*
* Note that due to how the hardware implements 64K GTT page support, we
* have some further complications:
*
* 1) The entire PDE (which covers a 2MB virtual address range), must
* contain only 64K PTEs, i.e mixing 4K and 64K PTEs in the same
* PDE is forbidden by the hardware.
*
* 2) We still need to support 4K PTEs for I915_MEMORY_CLASS_SYSTEM
* objects.
*
* To keep things simple for userland, we mandate that any GTT mappings
* must be aligned to and rounded up to 2MB. The kernel will internally
* pad them out to the next 2MB boundary. As this only wastes virtual
* address space and avoids userland having to copy any needlessly
* complicated PDE sharing scheme (coloring) and only affects DG2, this
* is deemed to be a good compromise.
