A follow-up to the last PR addressing a few issues

  • Tons of accuracy and stability/crash fixes in texture cache and blit engine
  • Vastly improved synchronization mechanism (DMA flush)
  • Implemented blit engine rotations on the GPU
  • Lays groundwork for the next task (variable sized framebuffers to preserve memory contents)

Tracker: #5708

kd-11 added some commits Mar 11, 2019

rsx: Fix zero-pitch textures
- Assumption here is that only texel (0, 0) is accessible. Inline with other pitch 0 operations.
- TODO: Verify pitch 0 does not advance in Y either
rsx/cache: Debugging bugs introduced by the atlas coverage check
- Figured out why it breaks things, ofc can't actually check for coverage when there is no proper fbo data persistence
vk/gl: Synchronization improvements
- Properly wait for the buffer transfer operation to finish before map/readback!
- Change vkFence to vkEvent which works more like a GL fence which is what is needed.
- Implement supporting methods and functions
- Do not destroy fence by immediately waiting after copying to dma buffer
rsx: Fix dst upload block region
- The section needed starts at image origin, not transfer origin!
vk/gl: Improve memory tag sync and test
- Properly pass parameters such as rsx-pitch to the surface store
- Do not crash if a surface fails verification in flip, use fall-back instead
rsx: Improvements to memory flush mechanism
- Batch dma transfers whenever possible and do them in one go
- vk: Always ensure that queued dma transfers are visible to the GPU before they are needed by the host
  Requires a little refactoring to allow proper communication of the commandbuffer state
- vk: Code cleanup, the simplified mechanism makes it so that its not necessary to pass tons of args to methods
- vk: Fixup - do not forcefully do dma transfers on sections in an invalidation zone! They may have been speculated correctly already

H.A.W.X can now go ingame without the need for CPU Blit. OpenGL can get ingame but has issues, while Vulkan can't get ingame at all.

OpenGL Issues

The game manages to get ingame but suffers from weird texture corruption that only appears ingame:
Broken Graphics
Correct textures:
Correct Graphics

Please let me know if there is any more information you would like me to supply.
OpenGL Log: OpenGL

Vulkan Issues

As the shaders are being compiled right before it would enter ingame, the screen freezes and spams the log with RSX: Blit request consists of an empty region descriptor!. It then proceeds to crash with RSX: class std::runtime_error thrown: Assertion Failed! Vulkan API call failed with unrecoverable error: Device lost (Driver crashed with unspecified error or stopped responding and recovered) (VK_ERROR_DEVICE_LOST).

Please let me know if there is any more information you would like me to supply.

Just delete your shader cache and the far cry 2 issue should be fixed.

@kd-11 this pr and #5675 fixed like 10 games with Fatal Error Issue and like 30 games overall improvement in graphics thanks a lot for the hard work and sorry if i post some games unrelated to this pr only was thinking maybe you could fixed : )

Beyond Two Souls also had an issue where cpu blit would make the colors look correct but when you using your ability the environment can randomly turn black. Since this PR makes it so you only need WCB now both look correct.

Before WCB only:
Before WCB and CPU blit:
After WCB only:
After WCB and CPU blit:
after with blit
