* glsl: be much more aggressive when skipping shader compilationTimothy Arceri2019-01-192-6/+10
| | | | | | | | | | | | | | | | | | | | Currently we only add a cache key for a shader once it is linked. However games like Team Fortress 2 compile a whole bunch of shaders which are never actually linked. These compiled shaders can take up a bunch of memory. This patch changes things so that we add the key for the shader to the cache as soon as it is compiled. This means on a warm cache we can avoid the wasted memory from these shaders. Worst case scenario is we need to compile the shaders at link time but this can happen anyway if the shader has been evicted from the cache. Reduces memory use in Team Fortress 2 from 1.3GB -> 770MB on a warm cache from start up to the game menu. V2: only add key to cache when compilation is successful.

* intel/fs: Don't touch accumulator destination while applying regioning ↵Jason Ekstrand2019-01-181-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | alignment rule In some shaders, you can end up with a stride in the source of a SHADER_OPCODE_MULH. One way this can happen is if the MULH is acting on the top bits of a 64-bit value due to 64-bit integer lowering. In this case, the compiler will produce something like this: mul(8) acc0<1>UD g5<8,4,2>UD 0x0004UW { align1 1Q }; mach(8) g6<1>UD g5<8,4,2>UD 0x00000004UD { align1 1Q AccWrEnable }; The new region fixup pass looks at the MUL and sees a strided source and unstrided destination and determines that the sequence is illegal. It then attempts to fix the illegal stride by replacing the destination of the MUL with a temporary and emitting a MOV into the accumulator: mul(8) g9<2>UD g5<8,4,2>UD 0x0004UW { align1 1Q }; mov(8) acc0<1>UD g9<8,4,2>UD { align1 1Q }; mach(8) g6<1>UD g5<8,4,2>UD 0x00000004UD { align1 1Q AccWrEnable }; Unfortunately, this new sequence isn't correct because MOV accesses the accumulator with a different precision to MUL and, instead of filling the bottom 32 bits with the source and zeroing the top 32 bits, it leaves the top 32 (or maybe 31) bits alone and full of garbage. When the MACH comes along and tries to complete the multiplication, the result is correct in the bottom 32 bits (which we throw away) and garbage in the top 32 bits which are actually returned by MACH. This commit does two things: First, it adds an assert to ensure that we don't try to rewrite accumulator destinations of MUL instructions so we can avoid this precision issue. Second, it modifies required_dst_byte_stride to require a tightly packed stride so that we fix up the sources instead and the actual code which gets emitted is this: mov(8) g9<1>UD g5<8,4,2>UD { align1 1Q }; mul(8) acc0<1>UD g9<8,8,1>UD 0x0004UW { align1 1Q }; mach(8) g6<1>UD g5<8,4,2>UD 0x00000004UD { align1 1Q AccWrEnable }; Fixes: efa4e4bc5fc "intel/fs: Introduce regioning lowering pass" Reviewed-by: Francisco Jerez <[email protected]>

| | | | | | | | | | | | | | | | | | We are not going to use userptr for anv block pool BOs anymore. However, so far we have been relying on the fact that userptr BOs are snooped on non-llc platforms. Let's make sure that the block pool BOs are still snooped, and we can also remove the clflush'ing that we do on all state buffers. And since we plan to remove the flushes, set the anv_bo_pool BOs to cached (snooped on non-LLC platforms) too. For LLC platforms, they are all cached by default, so this becomes a no-op. v5: - Add snooping to anv_bo_pool BOs too (Jason). - Remove anv_gem_set_domain.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible that we still have some space left in the block pool, but we try to allocate a state larger than that state. This means such state would start somewhere within the range of the old block_pool, and end after that range, within the range of the new size. That's fine when we use userptr, since the memory in the block pool is CPU mapped continuously. However, by the end of this series, we will have the block_pool split into different BOs, with different CPU mapping ranges that are not necessarily continuous. So we must avoid such case of a given state being part of two different BOs in the block pool. This commit solves the issue by detecting that we are growing the block_pool even though we are not at the end of the range. If that happens, we don't use the space left at the end of the old size, and consider it as "padding" that can't be used in the allocation. We update the size requested from the block pool to take the padding into account, and return the offset after the padding, which happens to be at the start of the new address range. Additionally, we return the amount of padding we used, so the caller knows that this happens and can return that padding back into a list of free states, that can be reused later. This way we hopefully don't waste any space, but also avoid having a state split between two different BOs. v3: - Calculate offset + padding at anv_block_pool_alloc_new (Jason). v4: - Remove extra "leftover".

* anv/allocator: Rework chunk return to the state pool.Rafael Antognolli2019-01-171-23/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit tries to rework the code that split and returns chunks back to the state pool, while still keeping the same logic. The original code would get a chunk larger than we need and split it into pool->block_size. Then it would return all but the first one, and would split that first one into alloc_size chunks. Then it would keep the first one (for the allocation), and return the others back to the pool. The new anv_state_pool_return_chunk() function will take a chunk (with the alloc_size part removed), and a small_size hint. It then splits that chunk into pool->block_size'd chunks, and if there's some space still left, split that into small_size chunks. small_size in this case is the same size as alloc_size. The idea is to keep the same logic, but make it in a way we can reuse it to return other chunks to the pool when we are growing the buffer. v2: - Include Jason's suggestions to the algorithm that returns chunks. - Update comments. v3: - Disallow returning 0 blocks (Jason). - fix min_size in the loop (Jason). - remove temporary variables (Jason) v4: - return_chunk() should never return blocks larger than pool->block_size.

* anv: Validate the list of BOs from the block pool.Rafael Antognolli2019-01-171-5/+49
| | | | | | | | | | | | | | | | | | | We now have multiple BOs in the block pool, but sometimes we still reference only the first one in some instructions, and use relative offsets in others. So we must be sure to add all the BOs from the block pool to the validation list when submitting commands. v2: - Don't add block pool BOs to the dependency list right before execbuf (Jason) - Call anv_execbuf_add_bo() to each BO in the block pools (Jason) - Use anv_execbuf_add_bo_set() to add surface state dependencies to execbuf. v3: - Add comment to the non-softpin case (Jason).

* anv: Split code to add BO dependencies to execbuf.Rafael Antognolli2019-01-171-23/+39
| | | | | | | | | This part of the anv_execbuf_add_bo() code is totally independent of the BO being added. Let's split it out, so we can reuse it later. v3: rename to anv_execbuf_add_bo_set (Jason). Reviewed-by: Jason Ekstrand <[email protected]>
* anv/allocator: Add support for a list of BOs in block pool.Rafael Antognolli2019-01-172-11/+59
| | | | | | | | | | | | | | | | | | | So far we use only one BO (the last one created) in the block pool. When we switch to not use the userptr API, we will need multiple BOs. So add code now to store multiple BOs in the block pool. This has several implications, the main one being that we can't use pool->map as before. For that reason we update the getter to find which BO a given offset is part of, and return the respective map. v3: - Simplify anv_block_pool_map (Jason). - Use fixed size array for anv_bo's (Jason) v4: - Respect the order (item, container) in anv_block_pool_foreach_bo (Jason).
