Ivan Chikish d34287b2cc Linux: use futex_waitv syscall for atomic waiting
In order to make this possible, some unnecessary features were removed.
2023-08-02 21:46:06 +03:00
Nekotekina 580bd2b25e Initial Linux Aarch64 support
* Update asmjit dependency (aarch64 branch)
* Disable USE_DISCORD_RPC by default
* Dump some JIT objects in rpcs3 cache dir
* Add SIGILL handler for all platforms
* Fix resetting zeroing denormals in thread pool
* Refactor most v128:: utils into global gv_** functions
* Refactor PPU interpreter (incomplete), remove "precise"
* - Instruction specializations with multiple accuracy flags
* - Adjust calling convention for speed
* - Removed precise/fast setting, replaced with static
* - Started refactoring interpreters for building at runtime JIT
*   (I got tired of poor compiler optimizations)
* - Expose some accuracy settings (SAT, NJ, VNAN, FPCC)
* - Add exec_bytes PPU thread variable (akin to cycle count)
* PPU LLVM: fix VCTUXS+VCTSXS instruction NaN results
* SPU interpreter: remove "precise" for now (extremely non-portable)
* - As with PPU, settings changed to static/dynamic for interpreters.
* - Precise options will be implemented later
* Fix termination after fatal error dialog

Eladash 1ee7b91646 Refactoring (#6143)
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.

Lassi Hämäläinen c963c51a60 Remove unnecessary header includes
- Manually removed lot of unneeded #includes to clean code and reduce
  compilation time
- Reordered some of the #includes to be in more logical order
2019-06-25 17:11:10 +03:00
Lassi Hämäläinen 499035512b Split Emu/Memory into more logical headers
- Add vm_locking.h and vm_reservation.h and move relevant functions
  and types to these headers.
- Change include order and make vm_ptr.h, vm_var.h and vm_ref.h headers
  usable invidually and them including vm.h instead of other way around
- Because usage of vm::ptr now requires including vm_ptr.h instead of
  vm.h updated multiple #includes
- Added additional #includes to vm_reservation.h and vm_locking to
  where vm::reservation_* and locking related functions are used
