It used to be handy that we only had a couple of headers, but over time intel_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes. Reviewed-by:

Having transitioned GEM over to using intel_context as its primary means of tracking the GEM context and engine combined and using i915_request_create(), we can move the older i915_request_alloc() helper function into selftests/ where the remaining users are confined. Signed-off-by:

We no longer need to track the active intel_contexts within each engine, allowing us to drop a tricky mutex_lock from inside unpin (which may occur inside fs_reclaim). Signed-off-by:

We switched to a tree of per-engine HW context to accommodate the introduction of virtual engines. However, we plan to also support multiple instances of the same engine within the GEM context, defeating our use of the engine as a key to looking up the HW context. Just allocate a logical per-engine instance and always use an index into the ctx->engines[]. Later on, this ctx->engines[] may be replaced by a user specified map. v2: Add for_each_gem_engine() helper to iterator within the engines lock v3: intel_context_create_request() helper v4: s/unsigned long/unsigned int/ 4 billion engines is quite enough. v5: Push iterator locking to caller Signed-off-by:

Chris Wilson authored
Our eventual goal is to rid request construction of struct_mutex, with the short term step of lifting the struct_mutex requirements into the higher levels (i.e. the caller must ensure that the context is already pinned into the GTT). In this patch, we pin GVT's shadow context upon allocation and so keep them pinned into the GGTT for as long as the virtual machine is alive, and so we can use the simpler request construction path safe in the knowledge that the hard work is already done.

Broadwater and the rest of gen4 do support being able to saving and reloading context specific registers between contexts, providing isolation of the basic GPU state (as programmable by userspace). This allows userspace to assume that the GPU retains their state from one batch to the next, minimising the amount of state it needs to reload and manually save across batches. v2: CONSTANT_BUFFER woes Running through piglit turned up an interesting issue, a GPU hang inside the context load. The context image includes the CONSTANT_BUFFER command that loads an address into a on-gpu buffer, and the context load was executing that immediately. However, since it was reading from the GTT there is no guarantee that the GTT retains the same configuration as when the context was saved, resulting in stray reads and a GPU hang. Having tried issuing a CONSTANT_BUFFER (to disable the command) from the ring before saving the context to no avail, we resort to patching out the instruction inside the context image before loading. This does impose that gen4 always reissues CONSTANT_BUFFER commands on each batch, but due to the use of a shared GTT that was and will remain a requirement. v3: ECOSKPD to the rescue Ville found the magic bit in the ECOSKPD to disable saving and restoring the CONSTANT_BUFFER from the context image, thereby completely avoiding the GPU hangs from chasing invalid pointers. This appears to be the default behaviour for gen5, and so we just need to tweak gen4 to match. v4: Fix spelling of ECOSKPD and discover it already exists Signed-off-by:

Ironlake does support being able to saving and reloading context specific registers between contexts, providing isolation of the basic GPU state (as programmable by userspace). This allows userspace to assume that the GPU retains their state from one batch to the next, minimising the amount of state it needs to reload, or manually save and restore. v2: Fix off-by-one in reading CXT_SIZE, and add a comment that the CXT_SIZE and context-layout do not match in bspec, but the difference is irrelevant as we overallocate the full page anyway (Ville).

Despite what I think the prm recommends, commit f2253bd9 ("drm/i915/ringbuffer: EMIT_INVALIDATE after switch context") turned out to be a huge mistake when enabling Ironlake contexts as the GPU would hang on either a MI_FLUSH or PIPE_CONTROL immediately following the MI_SET_CONTEXT of an active mesa context (more vanilla contexts, e.g. simple rendercopies with igt, do not suffer). Ville found the following clue, "[DevCTG+]: For the invalidate operation of the pipe control, the following pointers are affected. The invalidate operation affects the restore of these packets. If the pipe control invalidate operation is completed before the context save, the indirect pointers will not be restored from memory. 1. Pipeline State Pointer 2. Media State Pointer 3. Constant Buffer Packet" which suggests by us emitting the INVALIDATE prior to the MI_SET_CONTEXT, we prevent the context-restore from chasing the dangling pointers within the image, and explains why this likely prevents the GPU hang.
