* i965: Disentangle batch and state buffer flushing.Kenneth Graunke2017-09-145-40/+30
| | | | | | | | | | | | | | | | | | | | | | We now flush the batch when either the batchbuffer or statebuffer reaches the original intended batch size, instead of when the sum of the two reaches a certain size (which makes no sense now that they're separate buffers). With this change, we also need to update our "are we near the end?" estimate to require separate batch and state buffer space. I obtained these estimates by looking at the size of draw calls in the Unreal 4 Elemental Demo (using INTEL_DEBUG=flush and always_flush_batch=true). This will significantly impact the size of our batches. I've adjusted both down to try and be roughly similar to what we had been doing. On various benchmarks, a 20kB batch and 16kB statebuffer seemed to about right, but we may need to adjust this further. I tried a 16kB batch, but that regressed Synmark OglMultithread performance by a fair bit. 32kB for both would have significantly increased our batch sizes.

* i965: Grow the batch/state buffers if we need space and can't flush.Kenneth Graunke2017-09-141-5/+131
| | | | | | | | | | | | | | | | | | | | | | | | | Previously, we would just assert fail and die in this case. The only safeguard is the "estimated max prim size" checks when starting a draw (or compute dispatch or BLORP operation)...which are woefully broken. Growing is fairly straightforward: 1. Allocate a new larger BO. 2. memcpy the existing contents over to the new buffer 3. Set the new BO to the same GTT offset as the old BO. When emitting relocations, we write the presumed GTT offset of the target BO. If we changed it, we'd have to update all the existing values (by walking the relocation list and looking at offsets), which is more expensive. With the old BO freed, ideally the kernel could simply place the new BO at that offset anyway. 4. Update the validation list to contain the new BO. 5. Update the relocation list to have the GEM handle for the new BO (which we can skip if using I915_EXEC_HANDLE_LUT). v2: Update to handle malloc'd shadow buffers.

* i965: Use a separate state buffer, but avoid changing flushing behavior.Kenneth Graunke2017-09-147-82/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we emitted GPU commands and indirect state into the same buffer, using a stack/heap like system where we filled in commands from the start of the buffer, and state from the end of the buffer. We then flushed before the two met in the middle. Meeting in the middle is fatal, so you have to be certain that you reserve the correct amount of space before emitting commands or state for a draw. Currently, we will assert !no_batch_wrap and die if the estimate is ever too small. This has been mercifully obscure, but has happened on a number of occasions, and could in theory happen to any application that issues a large draw at just the wrong time. Estimating the amount of batch space required is painful - it's hard to get right, and getting it right involves a lot of code that would burn CPU time, and also be painful to maintain. Rolling back to a saved state and retrying is also painful - failing to save/restore all the required state will break things, and redoing state emission burns a lot of CPU. memcpy'ing to a new batch and continuing is painful, because commands we issue for a draw depend on earlier commands as well (such as STATE_BASE_ADDRESS, or the GPU being in a pirtacular state). The best plan is to never run out of space, which is totally doable but pretty wasteful - a pessimal draw requires a huge amount of space, and rarely occurs. Instead, we'd like to grow the batch buffer if we need more space and can't safely flush. We can't grow with a meet in the middle approach - we'd have to move the state to the end, which would mean updating every offset from dynamic state base address. Using separate batch and state buffers, where both fill starting at the beginning, makes it easy to grow either as needed. This patch separates the two concepts. We create a separate state buffer, with a second relocation list, and use that for brw_state_batch. However, this patch tries to retain the original flushing behavior - it adds the amount of batch and state space together, as if they were still co-existing in a single buffer. The hope is to flush at the same time as before. This is necessary to avoid provoking bugs caused by broken batch wrap handling (which we'll fix shortly). It also avoids suddenly increasing the size of the batch (due to state not taking up space), which could have a significant performance impact. We'll tune it later. v2: - Mark the statebuffer with EXEC_OBJECT_CAPTURE when supported (caught by Chris). Unfortunately, we lose the ability to capture state data on older kernels. - Continue to support the malloc'd shadow buffers.
