Vulkan

This is the start of a series about getting OpenGL ES 3.0 conformance on Vivante GC7000 hardware using the open-source etnaviv driver in Mesa. Thanks to Igalia for giving me the opportunity to spend some time on these topics. Where We Are etnaviv has supported GLES2 on Vivante GPUs for a long time. GLES3 support has been progressing steadily, but the remaining dEQP failures are the stubborn ones - the cases where the hardware doesn’t quite do what the spec says, and the driver has to get creative. ...

After years of working on etnaviv - a Gallium/OpenGL driver for Vivante GPUs - I’ve been wanting to get into Vulkan. As part of my work at Igalia, the goal was to bring VK_EXT_blend_operation_advanced to lavapipe. But rather than going straight there, I started with Honeykrisp - the Vulkan driver for Apple Silicon - as a first target: a real hardware driver to validate the implementation against before wiring it up in a software renderer. My first Vulkan extension, and my first real contribution to Honeykrisp. ...
