--- Comment #9 from V Stuart Foote <[email protected]> ---
Regards nVidia driver versioning: this from  Sascha Willems, the Vulkan
community's maintainer of the vulkan.gpuinfo.org repository--as sourced from
nVidia [1]

   <snip>
   This is the information I got from NVIDIA :

   Starting with MSB :
   10 bits = major version (up to r1023)
   8 bits = minor version (up to 255)
   8 bits = secondary branch version/build version (up to 255)
   6 bits = tertiary branch/build version (up to 63)
   </snip>

So nVidia intends encoding of a 4-part driver version string into uint32_t of
props.driverVersion. 

I recall Lubos being particular about difference between vendor's "marketing"
driver version and the actual Vulkan driver version that we needed for the
denylist, I guess some of that is at play here since we've got to
convert/extract the version string to test.
