opencl-icd virtual package(s)?

[Paul Wise]

[BCCed to OpenCL ICD implementation package maintainers]

I noticed that some packages have a dep on specific OpenCL ICD
packages, but don't dep on the opencl-icd virtual package(s).
Presumably any of the OpenCL ICDs work for most packages?

$ grep-aptavail --no-field-names --show-field Package --field
Depends,Recommends,Suggests --whole-pkg '(' --pattern .*opencl-icd.* --
and --not --pattern '^opencl-icd(-1\.[1]2-1)?$' ')'

In addition, I noticed that hashcat-nvidia (which presumably doesn't
need to depend on the opencl-icd virtual package) only depends on two
of the nvidia OpenCL ICD packages, while there are lots of other nvidia
OpenCL ICD packages that presumably work too.

I have attached a package list and dd-list for these issues.

Perhaps there should be a default-opencl-icd virtual package?

Perhaps lintian should flag situations where the dep isn't just
default-opencl-icd | opencl-icd? or is missing opencl-icd?

Thoughts?

PS: I noticed this because beignet-opencl-icd is RC-buggy. This is the
only OpenCL ICD implementation package I can see that supports Intel
Ivy Bridge, but it is hard to tell which other packages support this,
because some descriptions don't mention which hardware is supported.
