* configure.ac: rework -latomic checkThomas Petazzoni2018-06-131-17/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The configure.ac logic added in commit 2ef7f23820a67e958c2252bd81eb0458903ebf33 ("configure: check if -latomic is needed for __atomic_*") makes the assumption that if a 64-bit atomic intrinsic test program fails to link without -latomic, it is because we must use -latomic. Unfortunately, this is not completely correct: libatomic only appeared in gcc 4.8, and therefore gcc versions before that will not have libatomic, and therefore don't provide atomic intrinsics for all architectures. This issue was for example encountered on PowerPC with a gcc 4.7 toolchain, where the build fails with: powerpc-ctng_e500v2-linux-gnuspe/bin/ld: cannot find -latomic This commit aims at fixing that, by not assuming -latomic is available. The commit re-organizes the atomic intrinsics detection as follows: (1) Test if a program using 64-bit atomic intrinsics links properly, without -latomic. If this is the case, we have atomic intrinsics, and we're good to go. (2) If (1) has failed, then test to link the same program, but this time with -latomic in LDFLAGS. If this is the case, then we have atomic intrinsics, provided we link with -latomic. This has been tested in three situations: - On x86-64, where atomic instrinsics are all built-in, with no need for libatomic. In this case, config.log contains: GCC_ATOMIC_BUILTINS_SUPPORTED_FALSE='#' GCC_ATOMIC_BUILTINS_SUPPORTED_TRUE='' LIBATOMIC_LIBS='' This means: atomic intrinsics are available, and we don't need to link with libatomic. - On NIOS2, where atomic intrinsics are available, but some of them (64-bit ones) require using libatomic. In this case, config.log contains: GCC_ATOMIC_BUILTINS_SUPPORTED_FALSE='#' GCC_ATOMIC_BUILTINS_SUPPORTED_TRUE='' LIBATOMIC_LIBS='-latomic' This means: atomic intrinsics are available, and we need to link with libatomic. - On PowerPC with an old gcc 4.7 toolchain, where 32-bit atomic instrinsics are available, but not 64-bit atomic instrinsics, and there is no libatomic. In this case, config.log contains: GCC_ATOMIC_BUILTINS_SUPPORTED_FALSE='' GCC_ATOMIC_BUILTINS_SUPPORTED_TRUE='#' With means that atomic intrinsics are not usable.

* configure.ac/meson.build: Fix -latomic testNicolas Boichat2018-06-131-2/+4
| | | | | | | | | | | | | | | | | | | When compiling with LLVM 6.0 on x86 (32-bit) for Android, the test fails to detect that -latomic is actually required, as the atomic call is inlined. In the code itself (src/util/disk_cache.c), we see this pattern: p_atomic_add(cache->size, - (uint64_t)size); where cache->size is an uint64_t *, and results in the following link time error without -latomic: src/util/disk_cache.c:628: error: undefined reference to '__atomic_fetch_add_8' Fix the configure/meson test to replicate this pattern, which then correctly realizes the need for -latomic.

| | | | | | | | | | | | | | | | | | | | | The currently we use the singular CHECK_HEADER combined with explicit append to the DEFINES variable. That is a legacy misnomer, since it requires us to add $DEFINES to every piece that we build. Using the plural version of the helper sets the HAVE_ macro for us, plus ensures it's passed to the compiler - if config.h is available in there (not in the case of mesa) otherwise on the command line. In hindsight, we should replace all the AC_CHECK_{FUNC,HEADER} instances with the plural version (or even the _ONCE suffixed version) and drop the DEFINES hacks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra K1 and later use a GPU that can be driven by the Nouveau driver. But the GPU is a pure render node and has no display engine, hence the scanout needs to happen on the Tegra display hardware. The GPU and the display engine each have a separate DRM device node exposed by the kernel. To make the setup appear as a single device, this driver instantiates a Nouveau screen with each instance of a Tegra screen and forwards GPU requests to the Nouveau screen. For purposes of scanout it will import buffers created on the GPU into the display driver. Handles that userspace requests are those of the display driver so that they can be used to create framebuffers. This has been tested with some GBM test programs, as well as kmscube and weston. All of those run without modifications, but I'm sure there is a lot that can be improved. Some fixes contributed by Hector Martin <[email protected]>.

| | | | | | | | | | | | | | | | | | | | | | | | Part 1 of 2 (part 1 is autoconf changes, part 2 is C++ changes) When only a single SWR architecture is being used, this allows that architecture to be builtin rather than as a separate libswrARCH.so that gets loaded via dlopen. Since there are now several different code paths for each detected CPU architecture, the log output is also adjusted to convey where the backend is getting loaded from. This allows SWR to be used for static mesa builds which are still important for large HPC environments where shared libraries can impose unacceptable application startup times as hundreds of thousands of copies of the libs are loaded from a shared parallel filesystem.

* mesa: Add new fast mtx_t mutex type for basic use casesTimothy Arceri2017-11-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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%.

| | | | | | | | | | | | | | | | | | Add a check that tests whether the c++ compiler supports c++11, either by default, by adding the compiler flag -std=c++11, or by adding a compiler flag that the user has specified via the environment variable CXX11_CXXFLAGS. The test only does a very shallow check of c++11 support, i.e. it tests whether the define __cplusplus >= 201103L to confirm language support by the compiler, and it checks whether the header <tuple> is available to test the availability of the c++11 standard library. A make file conditional HAVE_STD_CXX11 is provided that is used in this patch to enable the test in st/mesa if C++11 support is available.
