version.h is now found via CMAKE_BINARY_DIR on the include path instead
of a hardcoded "build/version.h" path. This allows out-of-tree and
multi-config builds to each generate and find their own version header
without colliding.
When SuspendThread is called on an already-suspended thread, it would send
another pthread_kill signal, which would nest signal handlers and create
multiple outstanding sem_wait calls while Resume only posts once when count
reaches 0. Instead we increment suspend count and skip redundant signal.
Replace std::mutex/condition_variable with sem_wait/sem_post for thread
suspension, as WaitSuspended is called from the SIGRTMIN signal handler
where pthread_mutex_lock is not async-signal-safe.
The threading test is verifying that the timer fires, not that it fires
within a specific timeout, so increasing to 100 to keep it from failing
randomly. Also removing xenia-cpu-ppc-tests from list of default targets
as they take forever to run, they can still be run run using xb test
with --target xenia-cpu-ppc-tests explicitly.
BaseHeap::Dispose() walks the page table and calls
DeallocFixed(addr, 0, kRelease) for every allocated page region.
These addresses are within file-backed view mappings (i.e. guest memory).
On Windows, VirtualFree on file-mapped pages silently returns FALSE.
On POSIX, the code hit assert_always() and crashed. Changed to return false
to match Windows behavior.
Memory leaks from munmap(addr, 0):
Callers passed length=0 to DeallocFixed(kRelease). On Windows this works because
VirtualFree(addr, 0, MEM_RELEASE) means "release the entire region" — Windows
ignores the length parameter for MEM_RELEASE and always frees the whole
allocation. On POSIX, munmap(addr, 0) fails with EINVAL, so the memory was
silently leaked every time.
File-scope static initialization order is undefined across translation
units. Code that acquires the global critical region during early startup
could run before the mutex constructor, operating on uninitialized state.
A function-local static is constructed on first use, guaranteeing the
mutex is initialized before any caller can access it.
- Added codepath for "consume only" pass. This should resolve constant clicking in Source engine games.
- Added smaller performance improvements to decoder
Enable portability subset physical device enumeration.
Don't use Vulkan 1.1+ logical devices on Vulkan 1.0 instances due to the
VkApplicationInfo::apiVersion specification.
Make sure all extension dependencies are enabled when creating a device.
Prefer exposing feature support over extension support via the device
interface to avoid causing confusion with regard to promoted extensions
(especially those that required some features as extensions, but had those
features made optional when they were promoted).
Allow creating presentation-only devices, not demanding any optional
features beyond the basic Vulkan 1.0, for use cases such as internal tools
or CPU rendering.
Require the independentBlend feature for GPU emulation as working around is
complicated, while support is almost ubiquitous.
Move the graphics system initialization fatal error message to xenia_main
after attempting to initialize all implementations, for automatic fallback
to other implementations in the future.
Log Vulkan driver info.
Improve Vulkan debug message logging, enabled by default.
Refactor code, with simplified logic for enabling extensions and layers.
