            Bug ID: 501
           Summary: Discuss Vulkan requiring software API compliance and
                    how that meshes with our OPF compliance needs
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: CONFIRMED
          Severity: normal
          Priority: Normal
         Component: Specification
          Assignee: lkcl at lkcl.net
          Reporter: colepoirier at gmail.com

   NLnet milestone: ---

Based on a chat message Jacob sent in our Wed 23 September 2020
Libre-SOC-Microwatt Sync Jisti call:

"Note that vulkan is software API compliance, not ISA-level, so the compiler
can adapt b/w vulkan and the ISA."

This has important implications for our HDL, but even greater implications for
our to-be-proposed OpenPowerISA '3D GPU' or 'Unix without VSX' compliance
category requirements. If you don't mind, Jacob, can you fill in some of the
implications this has, as I think you know and I don't.
