* util: Fix disk_cache index calculation on big endianMatt Turner2017-11-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cache-test test program attempts to create a collision (using key_a and key_a_collide) by making the first two bytes identical. The idea is fine -- the shader cache wants to use the first four characters of a SHA1 hex digest as the index. The following program unsigned char array[4] = {1, 2, 3, 4}; int *ptr = (int *)array; for (int i = 0; i < 4; i++) { printf("%02x", array[i]); } printf("\n"); printf("%08x\n", *ptr); prints 01020304 04030201 on little endian, and 01020304 01020304 on big endian. On big endian platforms reading the character array back as an int (as is done in disk_cache.c) does not yield the same results as reading the byte array. To get the first four characters of the SHA1 hex digest when we mask with CACHE_INDEX_KEY_MASK, we need to byte swap the int on big endian platforms.

* util: Fix SHA1 implementation on big endianMatt Turner2017-11-251-1/+2
| | | | | | | | | | | The code defines a macro blk0(i) based on the preprocessor condition BYTE_ORDER == LITTLE_ENDIAN. If true, blk0(i) is defined as a byte swap operation. Unfortunately, if the preprocessor macros used in the test are no defined, then the comparison becomes 0 == 0 and it evaluates as true.

| | | | | | | | | | | | | | | | | Fences are now 4 bytes instead of 96 bytes (on my 64-bit system). Signaling a fence is a single atomic operation in the fast case plus a syscall in the slow case.

* mesa: Add new fast mtx_t mutex type for basic use casesTimothy Arceri2017-11-093-0/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While modern pthread mutexes are very fast, they still incur a call to an external DSO and overhead of the generality and features of pthread mutexes. Most mutexes in mesa only needs lock/unlock, and the idea here is that we can inline the atomic operation and make the fast case just two intructions. Mutexes are subtle and finicky to implement, so we carefully copy the implementation from Ulrich Dreppers well-written and well-reviewed paper: "Futexes Are Tricky" http://www.akkadia.org/drepper/futex.pdf We implement "mutex3", which gives us a mutex that has no syscalls on uncontended lock or unlock. Further, the uncontended case boils down to a cmpxchg and an untaken branch and the uncontended unlock is just a locked decr and an untaken branch. We use __builtin_expect() to indicate that contention is unlikely so that gcc will put the contention code out of the main code flow. A fast mutex only supports lock/unlock, can't be recursive or used with condition variables. We keep the pthread mutex implementation around as for the few places where we use condition variables or recursive locking. For platforms or compilers where futex and atomics aren't available, simple_mtx_t falls back to the pthread mutex. The pthread mutex lock/unlock overhead shows up on benchmarks for CPU bound applications. Most CPU bound cases are helped and some of our internal bind_buffer_object heavy benchmarks gain up to 10%.

| | | | | | | | | | | | “Saints Row: Gat out of Hell” benefits from this on slower CPUs in that usage spikes on individual cores are avoided, which in turn makes it harder to hit a bug which causes broken audio and the game to hang on exit. “Saints Row IV” appears to be fine either way, but also exhibits the audio breakage bug: glthread is therefore being enabled on the grounds that it should make it a little harder to hit that bug.
