- Fix reading of varying registers in FP
Different registers have different behavior
- Always write to varying registers. If a register is not written to, it is initialized to (0, 0, 0, 1)
- Reimplements two-sided lighting correctly without hacks
- Also bumps shader cache version
- The hw generates inaccurate values when doing perspective-correct
interpolation of vertex output attributes and makes the comparison (a ==
b) fail even when they are a fixed constant value.
- Increase equality tolerance when doing comparisons in fragment
shaders for NV cards only to work around this issue.
- Teepo fix
- The fixed-point D24S8 format does special Z clamping during compare which matches PS3 behaviour
- D32S8 is a floating point format and comparison with Dref > 1 always fails causing black edges/borders
- Improve support for float16_t by minimizing mixed inputs to functions
(ambiguous overloads)
- Minimize amount of downcasts in code by using opcode flags
- Re-enable float16_t support for vulkan
- Emulating f16 with f32 is not ideal and requires a lot of value clamping
- Using native data type can significantly improve performance and accuracy
- With openGL, check for the compatible extensions NV_gpu_shader5 and
AMD_gpu_shader_half_float
- With Vulkan, enable this functionality in the deviceFeatures if
applicable. (VK_KHR_shader_float16_int8 extension)
- Temporarily disable hw fp16 for vulkan
- Implements a mirror view of D24S8 data that accesses the stencil components.
Finishes the implementation of TEX2D_DEPTH_RGBA as the stencil component was previously missing from the reconstructed data
- Add a few missing destructors
Image classes are inherited a lot and I forgot to make the dtors virtual
- Reimplements render target views used for sampling
- Optimizes access using an encoded control token
- Adds proper encoding for 24-bit textures (DRGB8 -> ORGB/OBGR)
- Adds proper encoding for ABGR textures (ABGR8 -> ARGB8)
- Silence some compiler warnings as well
- TODO: Real texture views for OGL current method is a hack
- Separate TXB from TXL: They are completely different!
- Properly perform TMU emulation in the fragment shader. Implemens SRGB conversion and alphakill at the moment
- Properly perform ROP emulation in the fragment shader. Implements FRAMEBUFFER_SRGB. While support on the chip looks to be incomplete (and wierd), it does work
- Document some more bits in SHADER_CONTROL register
According to the NV_fragment_program spec, its not feasible to have 16-bit depth wries
NOTE: NV_fragement_program precedes NV_fragment_program2 which is very
close to what RSX consumes. It is hardware from that era afterall
- Do not add unused subroutines in shaders unless necessary
-- makes shaders easier to read and disassembled spir-v has less clutter
- glsl: Replace switch block with lookup table
- Limits buffer size to min 720 in the Y axis (1024 section causes conflicts in some cases - TODO)
rsx: Fixups to allow large textures for blit operation
- Also includes checks for both leaking sections and blit regions for vulkan
hotfix for hanging when using WCB
addendum - unlock both ro and no blocks before attempting to copy memory blocks
gl: Fixups for ARB_explicit_uniform_location
- Forces glsl v 430 to make use of the extension
rsx/vk: Rework texture cache to minimize recursive access violations
- Also modifies the vulkan commandbuffer begin/end/submit mechanism
gl: Fix cached_texture_section::is_flushable to take memory protection into account
rsx: Fix blit dst offset calculation
* Update VKFragmentProgram.cpp
added missing exponent parameter
* fixed misplaced exponent in VKFragmentProgram.cpp
parameter that belonged to pow() was being passed to exp() instead, causing the shader compilation to fail
* fix for opengl fog_mode exponential2
same fix as the vulkan version
* directx fog_mode exponential2 fix
misplaced parameter
* directx fog_mode exponential2_abs fix
* vulkan fog_mode exponential2_abs fix
* opengl fog_mode exponential2 fix
* vk: Zero-initialize some more structs
* gl: Clean up fragment program generation code
* vk: Enable alpha kill
* vk: Fix surface clear; redirect output for surface_type:b
* vk: Tie renderpass to program object to avoid incompatible passes
