* Use Linux timers for sleeps up to 1ms (v3)
The current sleep timer implementation basically offers two variants. Either
wait the specified time exactly with a condition variable (as host) or use a
combination of it with a thread yielding busy loop afterwards (usleep timer).
While the second one is very precise it consumes CPU loops for each wait call
below 50us. Games like Bomberman Ultra spam 30us waits and the emulator hogs
low power CPUs. Switching to host mode reduces CPU consumption but gives a
~50us penalty for each wait call. Thus extending all sleeps by a factor of
more than two.
The following bugfix tries to improve the system timer for Linux by using
Linux native timers for small wait calls below 1ms. This has two effects.
- Host wait setting has much less wait overhead
- usleep wait setting produces lower CPU overhead
Move source files to Emu/GDB.cpp, GDB.h
Remove "WITH_GDB" option, enable GDB Server by default.
Change class name to gdb_thread.
Alias for external access gdb_server.
Change config option name to "GDB Server"
Bind on 127.0.0.1 by default.
Move se_t and se_storage to util/endian.hpp
Use single template instead of two specializations.
Add minor optimization for MSVC.
Remove v128 dependency.
Try to enable intrinsics for unaligned data.
Fix minor bug in u16/u32/u64 specializations.
Prefer vm::ptr<>::ptr over vm::get_addr.
Prefer vm::_ptr/base over vm::g_base_addr with offset.
Added methods atomic_t<>::bts and atomic_t<>::btr .
Removed obsolute rsx:🧵:Read/WriteIO32 methods.
Removed wrong check in semaphore_release.
Added handling for PUTRx commands for RawSPU MFC proxy.
Prefer overloaded methods of v128 instead of _mm_... in VPKSHUS ppu interpreter precise.
Fixed more potential overflows that may result in wrong behaviour.
Added io/size alignment check for sys_rsx_context_iounmap.
Added rsx::constants::local_mem_base which represents RSX local memory base address.
Removed obsolute rsx:🧵:main_mem_addr/ioSize/ioAddress members.
-Indentation warnings
-prevent shift overflow
-This was declared extern in all contexts. Remove this for initialization
-Fix main return types. OH CANADA!
-Silence extraneos 'unused expression' warning
-Force use return value (warning)
-Remove tautological compare copy-pasta (char always < 256)
- Multiple header files where missing #includes to other headers that
where used in the header. Correct header was included in correct
order in source files which caused everything to compile.
- Added missing #includes so header files correctly include all their
dependencies and fixes problems with IDEs being unable to parse
headers correctly due to missing symbols
Misc: fix EH frame registration (LLVM, non-Windows).
Misc: constant-folding bitcast (cpu_translator).
Misc: add syntax for LLVM arrays (cpu_translator).
Misc: use function names for proper linkage (SPU LLVM).
Changed function search and verification in Giga mode.
Basic stack frame layout analysis.
Function detection in Giga mode.
Basic use of new information in SPU LLVM.
Fixed jump table compilation in SPU LLVM.
Disable broken optimization in Accurate xfloat mode.
Make compiled SPU modules position-independent in SPU LLVM.
Optimizations include but not limited to:
* Compiling SPU functions as native functions when eligible
* Avoiding register context write-out
* Aligned stack assumption (CWD alike instruction)
* Implement both RawSPU and threaded SPU page fault recovery
* Guard page_fault_notification_entries access with a mutex
* Add missing lock in sys_ppu_thread_recover_page_fault/get_page_fault_context
* Fix EINVAL check in sys_ppu_thread_recover_page_fault, previously when the event was not found begin() was erased and
CELL_OK was returned.
* Fixed page fault recovery waiting logic:
- Do not rely on a single thread_ctrl notification (unsafe)
- Avoided a race where ::awake(ppu) can be called before ::sleep(ppu) therefore nop-ing out the notification
* Avoid inconsistencies with vm flags on page fault cause detection
* Fix sys_mmapper_enable_page_fault_notification EBUSY check
from RE it's allowed to register the same queue twice (on a different area) but not to enable page fault notifications twice
Is a memory manager for ASMJIT, replaces asmjit::JitRuntime
Unified memory manager for ASMJIT and LLVM
Unified SPU trampoline generation
Remove previous workarounds
Allow parallel compilation of SPU code, both at startup and runtime
Remove 'SPU Shared Runtime' option (it became obsolete)
Refactor spu_runtime class (now is common for ASMJIT and LLVM)
Implement SPU ubertrampoline generation in raw assembly (LLVM)
Minor improvement of balanced_wait_until<> and balanced_awaken<>
Make JIT MemoryManager2 shared (global)
Fix wrong assertion in cond_variable
Implement helper functions balanced_wait_until and balanced_awaken
They include new path for Windows 8.1+ (WaitOnAddress)
shared_mutex, cond_variable, cond_one, cond_x16 modified to use it
Added helper function utils::popcnt16
Replace most semaphore<> with shared_mutex
lf_queue<>: unbound FIFO queue with dynamic linked-list
lf_value<>: concurrently-assignable value readable without locking at the cost of memory (using dynamic linked list)
Add atomic_t<>::compare_exchange
Rewrite to use unsigned arithmetic, shrink to u32
Ensure zero default unlocked state (will need it later)
Inline all public methods, rewrite lock_upgrade()
Remove try_lock_degrade(), lock_degrade() methods
Implement lock_downgrade() (now trivial)
Remove is_reading(), added is_free()
Added reader_lock::try_upgrade()
- ASSUME now uses __builtin_assume in clang
- ASSERT defined as a wrapper around verify
- AUDIT aliases ASSERT when _DEBUG or _AUDIT are set, otherwise empty
* CMake: Refactor build to multiple libraries
- Refactor CMake build system by creating separate libraries for
different components
- Create interface libraries for most dependencies and add 3rdparty::*
ALIAS targets for ease of use and use them to try specifying correct
dependencies for each target
- Prefer 3rdparty:: ALIAS when linking dependencies
- Exclude xxHash subdirectory from ALL build target
- Add USE_SYSTEM_ZLIB option to select between using included ZLib and
the ZLib in CMake search path
* Add cstring include to Log.cpp
* CMake: Add 3rdparty::glew interface target
* Add Visual Studio CMakeSettings.json to gitignore
* CMake: Move building and finding LLVM to 3rdparty/llvm.cmake script
- LLVM is now built under 3rdparty/ directory in the binary directory
* CMake: Move finding Qt5 to 3rdparty/qt5.cmake script
- Script has to be included in rpcs3/CMakeLists.txt because it defines
Qt5::moc target which isn't available in that folder if it is
included in 3rdparty directory
- Set AUTOMOC and AUTOUIC properties for targets requiring them (rpcs3
and rpcs3_ui) instead of setting CMAKE_AUTOMOC and CMAKE_AUTOUIC so
those properties are not defined for all targets under rpcs3 dir
* CMake: Remove redundant code from rpcs3/CMakeLists.txt
* CMake: Add BUILD_LLVM_SUBMODULE option instead of hardcoded check
- Add BUILD_LLVM_SUBMODULE option (defaults to ON) to allow controlling
usage of the LLVM submodule.
- Move option definitions to root CMakeLists
* CMake: Remove separate Emu subtargets
- Based on discussion in pull request #5032, I decided to combine
subtargets under Emu folder back to a single rpcs3_emu target
* CMake: Remove utilities, loader and crypto targets: merge them to Emu
- Removed separate targets and merged them into rpcs3_emu target as
recommended in pull request (#5032) conversations. Separating targets
probably later in a separate pull request
* Fix relative includes in pad_thread.cpp
* Fix Travis-CI cloning all submodules needlessly
Preprocess . and .. correctly

Remove vm::ptr operator %
This was a bad idea but explicit_bool_t was created almost for it
Other removed types are unused and have little to no meaning
Remove "atomic operator" classes
Remove test, test_and_set, test_and_reset, test_and_complement global functions
Simplify atomic_t<> with constexpr if, remove some garbage
Redesign bs_t<> to use class, mark its methods constexpr
Implement atomic_bs_t<> for optimizations
Remove unused __bitwise_ops concept (should be in other header anyway)
Bitsets can now be tested via safe bool conversion
