Bug description:
Description:
Mesa Vulkan VK_INTEL_performance_query extension
Adds support to Mesa and kernel for a new Vulkan extension called
“VK_INTEL_performance_query” enabling exposure of Intel based GPU metric
collection. Enable support for query based metrics in Linux Vulkan for Intel
Graphics Performance Analyzers (Intel GPA), Enables metrics to be collected on
Integrated graphics beginning with Broadwell (Skylake, Kabylake, Coffeelake,
Icelake, …).
Intel GPA already supports Linux OpenGL hardware based metrics. Obtaining
hardware metrics for Vulkan based workloads is essential to make GPA’s
profiling capabilities usable.
Several internal customers and ISV’s rely on GPA to enable best in class game
performance on Intel hardware.
Key for hardware design win that depends upon holistic Vulkan support in
Linux including query based performance metric analysis.
