* anv/pipeline: Add skeleton support for spilling to bindlessJason Ekstrand2019-04-194-27/+122
| | | | | | | | | | If the number of surfaces or samplers exceeds what we can put in a table, we will want to spill out to bindless. There is no bindless support yet but this gets us the basic framework that will be used by later commits.

* anv/pipeline: Sort bindings by most used firstJason Ekstrand2019-04-191-40/+95
| | | | | | | | | This commit just sorts the bindings by how often they're used vs the array size of the binding. This will let us make more nuanced decisions about what goes in the binding table vs. what to make bindless.

* anv: Put image params in the descriptor set buffer on gen8 and earlierJason Ekstrand2019-04-196-124/+109
| | | | | | | | | | | | This is really where they belong; not push constants. The one downside here is that we can't push them anymore for compute shaders. However, that's a general problem and we should figure out how to push descriptor sets for compute shaders. This lets us bump MAX_IMAGES to 64 on BDW and earlier platforms because we no longer have to worry about push constant overhead limits.

* anv: Make all VkDeviceMemory BOs resident permanentlyJason Ekstrand2019-04-194-46/+48
| | | | | | | | | | | | | | | | | | | | | We spend a lot of time in the driver adding things to hash sets to track residency. The reality is that a properly built Vulkan app uses large memory objects and sub-allocates from them. In a typical frame, most of if not all of those allocations are going to be resident for the entire frame so we're really not saving ourselves much by tracking fine-grained residency. Just throwing everything in the validation list does make it a little bit more expensive inside the kernel to walk the list and ensure that all our VA is in order. However, without relocations, the overhead of that is pretty small. If we ever do run into a memory pressure situation where the fine- grained residency could even potentially help, we would likely be swapping one page out to make room for another within the draw call and performance is totally lost at that point. We're better off swapping out other apps and just letting ours run a whole frame. Reviewed-by: Lionel Landwerlin <[email protected]> Reviewed-by: Caio Marcelo de Oliveira Filho <[email protected]>

| | | | | | | | | | | | | | | | We empty the cache sets when flushing the batch, at which point we need to add any framebuffer related BOs even though the bindings haven't changed. So, we now do the cache set tracking unconditionally. For now, we continue skipping resolve work based on the same conditions in the predraw functions - the thinking is if we didn't trigger resolves, there's nothing to update here.

* intel/fs: Account for live range lengths in spill costsJason Ekstrand2019-04-181-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current register allocator has a concept of "spill benefit" which is based on the number of nodes with which a given node interferes. The idea is that you want to spill stuff with high interference because those are the most likely registers to help when spilling. However, this fails to take into account the length of the live range so the allocator frequently picks "cheap" (not many uses) registers which are actually very short lived and so spilling them doesn't help with the pressure situation. This commit takes into account the length of the live range to make long-lived registers more likely to get spilled than short-lived ones. This encourages the spill chooser to choose slightly larger registers which will affect a larger area of the program and hopefully we have to spill fewer of them to get the same reduction in over-all register pressure.
