- Renormalizes arbitrary N-bit values as 8-bit normalized.
- NV hardware performs integer normalization at 8 bits if the size is less than 8.
- This can cause significant arithmetic drift because the error is multiplied by a huge number when sampling.
* 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.
- Allows frameskipping to occur naturally if RSX thread is bombarded with flip requests but just jumping to the last one if possible
- See request_emu_flip() for async frame submission and implicit skipping
- Also allows display queue to fill faster than the flip thread can drain the queue
- Separate displayed statistics from actual backend statistics.
Allows asynchronous flipping to work correctly as it just uses display stats.
The real stats are used by the frame scope marker to determine behavior like engaging the FIFO optimizer or skipping draw calls correctly.
- Add an explicit frame scope marker tied in with the queue_prepare command
Since queue_prepare is emitted at the end of a frame, it can be used as end-of-frame in games that emit this
- If this command is not emitted, fifo flatenner and frameskip will not work
- Do not allow offloader to handle its own faults. Serialize them on RSX instead.
This approach introduces a GPU race condition that should be avoided with improved synchronization.
- TODO: Use proper GPU-side synchronization to avoid this situation
- 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
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.
- Do not bind companion framebuffer when clearing single aspect; let the
contest mechanism sort it out instead
- Do not prematurely tag framebuffers, instead only do so at
write-confirmation time. Should avoid false tagging if setup does not
allow a render to occur.
* Restore stack in fifo error handling
* Update get register after the cmd execution
* Fix put pause in the middle of command
* Add restore points when branching to self
* Precise nopcmd detection
* Test all invalid cmds for early treatment of queue corruption
- Tries to detect when FIFO preprocessing is beneficial and only enables optimizations if the benefit outweighs the cost
- Current threshold is at least 500 draw calls saved at over 2000 draw calls to justify the overhead
- TODO: More tuning for other CPUs
