* Use atomic waitables instead instead of global thread wait as often as possible.
* Add ::is_stopped() and and ::is_paued() which can be used in atomic loops and with atomic wait. (constexpr cpu flags test functions)
* Fix notification bug of sys_spu_thread_group_exit/terminate. (old bug, enhanced by #9117)
* Function time statistics at Emu.Stop() restored. (instead of current "X syscall failed with 0x00000000 : 0")
- Fix special case where n=f making (f-n) = 0
- Dynamically update depth range by setting dirty bits
- Fix depth bounds when n=f and bounds test is disabled
- Those strange offsets noted in some games seem to match to subpixel addressing.
For example, when scaling down by a factor of 4, a pixel offset of 2 will end up inside pixel 0 of the output
- Some games use texture semaphore for zcull sync which is rather bizzare.
However, it works on realhw as the depth test happens before fragment shader completion
- Due to the high performance penalty incurred by this act, this
behavior is only enabled by the "strict rendering mode" option.
- Properly synchronize DMA transfers when handling RSX pipeline
barriers. Texture read barrier is used to signify completion of DMA
routines and is often used to signal that Cell can overwrite vertex
data!
- Prefer lazy retire model. Sync commands are sent out and the reports will be
retired when they are available without forcing.
- To make this work with conditional rendering, hardware support is
required where the backend will automatically determine visibility by
itself during rendering.
- Allow delaying report flushes triggered by image_in or buffer_notify
- When the report is ready, all the delayed transfers will automatically
be done.
- TODO: Make this configurable?
This lowers the relative cost of this function from ~2.25% to ~1.80% on
gcc 9 which I found quite surprising, some of it probably gets inlined
better in the callers, but I haven’t been able to isolate which parts.
* allow sys_rsx_device_map to be called twice: in this case the DEVICE address retrived from the previous call returned
* Add ENOMEM checks for sys_rsx_memory_allocate and sys_rsx_context_allocate
* add EINVAL check for sys_rsx_context_allocate if memory handle is not found
* Separate sys_rsx_device_map allocation from sys_rsx_context_allocate's
* Implement sys_rsx_memory_free; used by cellGcmInit upon failure
* Added context_id checks
* Throw if sys_rsx_context_allocate was called twice.
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.
- ZCULL queue was updated to one-per-cb but the conditional render sync hint was not updated.
- Do not unconditionally flush the queue unless the upcoming ref is contained in the active CB.
- This avoids spamming queue flush, which frees up resources and improves performance
- Merge viewport raster window and scissor into one clipping region
- Viewport raster clip is different from viewport geometry clipping in
hardware as the latter is configurable separately
vm::spu max address was overflowing resulting in issues, so cast to u64 where needed. Fixes#6145.
Use vm::get_addr instead of manually substructing vm::base(0) from pointer in texture cache code.
Prefer std::atomic_thread_fence over _mm_?fence(), adjust usage to be more correct.
Used sequantially consistent ordering in semaphore_release for TSX path as well.
Improved memory ordering for sys_rsx_context_iounmap/map.
Fixed sync bugs in HLE gcm because of not using atomic instructions.
Use release memory barrier in lwsync for PPU LLVM, according to this xbox360 programming guide lwsync is a hw release memory barrier.
Also use release barrier where lwsync was originally used in liblv2 sys_lwmutex and cellSync.
Use acquire barrier for isync instruction, see https://devblogs.microsoft.com/oldnewthing/20180814-00/?p=99485
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.
- 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
- When reverse scanning, offsets are inverted and offset value of 0 is logically equivalent to an offset of -1
- Add an explicit message if clipping happens to avoid silent errors/bugs
