* util: Change the pointer hashing functionThomas Helland2017-05-221-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use our knowledge that pointers are at least 4 byte aligned to remove the useless digits. Then shift by 6, 10, and 14 bits and add this to the original pointer, effectively folding in the entropy of the higher bits of the pointer into a 4-bit section. Stopping at 14 means we can add the entropy from 18 bits, or at least a 600Kbyte section of memory. Assuming that ralloc allocates from a linearly allocated heap less than this we can make a very efficient pointer hashing function for our usecase. Even if we are not on an architecture that is 4 byte aligned, there is still a high big chance that the thing we are allocating is at least 8 bytes in size, so even then we will have entropy into the third bit. The 4 bit increment on the shifts is chosen rather arbitrarily; if we had chosen a 3 bit increment we would need to add another xor to cover a decently sized memorypool. Increasing it to 5 bits would spread our entropy more, possibly hurting us with more collisions on hash tables of size less than 32. With a hash table of size 16 there are a max of 11 entries, and we can assume that with such a small table collisions are not that painfull. This allows us to hash the whole 32 or 64 bit pointer at once, instead of running FNV1a, looping through each byte and doing increments, decrements, muls, and xors on every byte. This cuts _mesa_hash_data from 1.5 % on profiles, to making _mesa_hash_pointer show up with a 0.09% share. Collisions on insertion actually seems to be ever so slightly lower with this hash function, as found by printing a loop counter and sorting the data. perf stat shows a 1.5% reduction in instruction count, and a 5% reduction in stalled cycles. Shader-db runtime goes from 225 to 220 seconds. No instruction-count changes in shader-db, but there are some minor changes in cycle-count that is likely caused by nir walking a set in some of its passes, and this causing a different ordering. That might eventually lead to a difference in register allocation. However, the effect is a net positive; total cycles in shared programs: 24739550 -> 24738482 (-0.00%) cycles in affected programs: 374468 -> 373400 (-0.29%) helped: 178 HURT: 49 Reviewed-by: Marek Olšák <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

* util/disk_cache: remove percentage based max cache limitTimothy Arceri2017-04-281-6/+2
| | | | | | | | | | | | | | | | The more I think about it the more this seems like a bad idea. When we were deleting old cache dirs this wasn't so bad as it was unlikely we would ever hit the actual limit before things were cleaned up. Now that we only start cleaning up old cache items once the limit is reached the a percentage based max cache limit is more risky. For the inital release of shader cache I think its better to stick to a more conservative cache limit, at least until we have some way of cleaning up the cache more aggressively.

* disk_cache: use block size rather than file sizeTimothy Arceri2017-04-271-5/+11
| | | | | | | | | | | | | | | | The majority of cache files are less than 1kb this resulted in us greatly miscalculating the amount of disk space used by the cache. Using the number of blocks allocated to the file is more conservative and less likely to cause issues. This change will result in cache sizes being miscalculated further until old items added with the previous calculation have all been removed. However I don't see anyway around that, the previous patch should help limit that problem. Cc: "17.1" <[email protected]> Reviewed-and-Tested-by: Michel Dänzer <[email protected]>

* util/disk_cache: add a write helperGrazvydas Ignotas2017-03-211-14/+23
| | | | | | | | | | | | | Simplifies the write code a bit and handles EINTR. V2: (Timothy Arceri) Drop EINTR handling. To do it properly we would need a retry limit but it's probably best to just avoid trying to write if we hit EINTR and try again next time we see the program.

| | | | | | | | | I haven't seen this causing problems in practice, but for correctness we should also check if rename succeeded to avoid breaking accounting and leaving a .tmp file behind. Signed-off-by: Grazvydas Ignotas <[email protected]> Reviewed-by: Timothy Arceri <[email protected]>
* util/disk_cache: delete .tmp if target existsGrazvydas Ignotas2017-03-201-1/+3
| | | | | | | | | | | At the time of target file check, .tmp file is already created and file lock is held, so we should remove the .tmp, like in other error paths. With this, piglit no longer leaves large amount of empty .tmp files behind, which waste directory entries and may interfere with eviction.
