| | | | | | | | | | | | | | | | | | | | | | In order to be coherent with the pre-existent API for half floats, this new API for double is the one meant to be used when doing double to float conversions. It is no more than a wrapper for the softfloat.h API but we meant to keep that one private. v2: - Fix bug in _mesa_double_to_float_rtz() in the inf/nan detection using the exponent value. v3: - Replace custom f64 -> f32 implementations with the softfloat one (Andres). v4: - Added API usage clarifying comments (Caio).

* meson: Add tests to suitesDylan Baker2018-11-201-3/+6
| | | | | | | | | | | | | | | | Meson test has a concepts of suites, which allow tests to be grouped together. This allows for a subtest of tests to be run only (say only the tests for nir). A test can be added to more than one suite, but for the most part I've only added a test to a single suite, though I've added a compiler group that includes nir, glsl, and glcpp tests. To use this you'll need to invoke meson test directly, instead of ninja test (which always runs all targets). it can be invoked as: `meson test -C builddir --suite $suitename` (meson test has addition options that are pretty useful).

* move u_math to src/utilDylan Baker2018-09-071-0/+2
| | | | | | | | | | | | | | | Currently we have two sets of functions for bit counts, one in gallium and one in core mesa. The ones in core mesa are header only in many cases, since they reduce to "#define _mesa_bitcount popcount", but they provide a fallback implementation. This is important because 32bit msvc doesn't have popcountll, just popcount; so when nir (for example) includes the core mesa header it doesn't (and shouldn't) link with core mesa. To fix this we'll promote the version out of gallium util, then replace the core mesa uses with the util version, since nir (and other non-core mesa users) can and do link with mesautils.

| | | | | | | | | | | | | | | | | | | | | | | | This is a simple, invasive, liberally licensed red-black tree implementation. It's an invasive data structure similar to the Linux kernel linked-list where the intention is that you embed a rb_node struct the data structure you intend to put into the tree. The implementation is mostly based on the one in "Introduction to Algorithms", third edition, by Cormen, Leiserson, Rivest, and Stein. There were a few other key design points: * It's an invasive data structure similar to the [Linux kernel linked list]. * It uses NULL for leaves instead of a sentinel. This means a few algorithms differ a small bit from the ones in "Introduction to Algorithms". * All search operations are inlined so that the compiler can optimize away the function pointer call.

* util: Add a virtual memory allocatorJason Ekstrand2018-05-311-0/+2
| | | | | | | | | | | | | | | | | | | | | | This is simple linear-walk first-fit allocator roughly based on the allocator in the radeon winsys code. This allocator has two primary functional differences: 1) It cleanly returns 0 on allocation failure 2) It allocates addresses top-down instead of bottom-up. The second one is needed for Intel because high addresses (with bit 47 set) need to be canonicalized in order to work properly. If we allocate bottom-up, then high addresses will be very rare (if they ever happen). We'd rather always have high addresses so that the canonicalization code gets better testing. v2: - [scott-ph] remove _heap_validate() if NDEBUG is defined (Jordan) Reviewed-by: Scott D Phillips <[email protected]> Tested-by: Scott D Phillips <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
* disk cache: Link with -latomic if necessaryThierry Reding2018-03-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The disk cache implementation uses 64-bit atomic operations. For some architectures, such as 32-bit ARM, GCC will not be able to translate these operations into atomic, lock-free instructions and will instead rely on the external atomics library to provide these operations. Check at configuration time whether or not linking against libatomic is necessary and if so, create a dependency that can be used while linking the mesautil library. This is the meson equivalent of 2ef7f23820a6 ("configure: check if -latomic is needed for __atomic_*").

* mesa: Add new fast mtx_t mutex type for basic use casesTimothy Arceri2017-11-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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%.
