Shahbaz Youssefi c26011b8 2023-04-11T15:16:29 Vulkan: Make advanced blend alpha div workaround permanent This workaround turned out to affect pretty much every driver, and numerous GL implementations were found to work around it similarly to ANGLE. It seems like this workaround may only be necessary for colorburn and colordodge, but for now ANGLE applies it to all modes.

Shahbaz Youssefi 6f80f0f0 2022-08-06T02:29:19 Translator: Clean up the compile flag passing interface Historically, compile flags were sent to the translator as a bitmask. Recently, we were getting close to running out of bits. Additionally, direct-to-metal work had started to introduce constants to be passed to the translator, which were misplaced in ShBuiltInResources and Caps. Recent work on Pixel Local Storage adds even more constants, aggravating the situation. In this change, the interface to passing compile flags is reworked. A struct is passed (instead of a bitmask) that has one bit for each flag. This can be indefinitely extended. Additionally, the constants needed by metal and PLS are also placed in this struct. In turn, the backends can set these options directly, and don't have to hack them into Caps to further get hacked into ShBuiltInResources.

Shahbaz Youssefi 2df17a12 2022-05-25T16:18:37 Vulkan: Pack driver uniforms Previously 5 vec4s were used for driver uniforms + 2 vec4s if specialization constants couldn't be supported. The driver uniforms are rearranged and packed such that only 2 vec4s are normally used, which include fallback for specialization constants as well. In the future, most of the specialization constants may turn into uniforms, and this change prepares for that. Additional uniforms are used (3 vec4s) only if common extensions are missing; transform feedback and bresenham lines. This change makes it more practical for driver uniforms to be turned into push constants. Additionally, these uniforms could potentially be loaded and cached at the beginning of the shader for more efficient memory access. On Pixel6, with this change, the traces show no difference in wall time. On most traces, CPU time shows up to ~7% improvement.

Shahbaz Youssefi 98c2e169 2022-05-20T16:17:49 Vulkan: Reduce pre-rotation spec const to bool The specialization constant now only dictates whether x and y should be swapped. The complete 8 possible states of rotation and y-flip are achieved by using this swap in combination with a driver uniform for x and y flip. Swapping is still a specialization constant to avoid degrading performance of dFdx/dFdy which otherwise would need both to be evaluated instead of one. On platforms which don't support pre-rotation, the specialization constant will never change and driver uniforms entirely govern y-flip. On platforms that do support pre-rotation, only two variations of the pipeline are needed.

Shahbaz Youssefi c5271e8e 2022-04-04T23:28:35 Vulkan: Emulate GL_KHR_blend_equation_advanced Based on a change by Brandon Schade <b.schade@samsung.com> In the translator, when advanced blend is enabled, an input attachment is added. Based on the listed advanced blend equations, emulation code is added that performs those equations' functions. The blend equation itself is passed through a driver uniform. Note that the advanced blend extension only allows a single output to use advanced blend, and that should be at location 0. In the Vulkan backend, when advanced blend is used, the driver uniform to select the equation is updated and normal blending is disabled.
