Oops, I almost made one big mistake. It turns out that MooWrapper still has
apps that run on older GPUs, but it would be the only project that I know of
that still does.

If no projects have CAL apps, I don't see any reason to keep the CAL
device enumeration code. Anyone else?

Correct me if I am wrong, but the first section would be
populated with values if the CAL detection code was working
properly. Even when the ATI library was found, the values were not
reported because Boinc I believe was not enumerating the CAL targets
correctly. In the Opencl section notice that the number of SIMD
units is correctly reported, but for some reason Boinc is detecting
an error returned by the driver. Don't know if it is a problem in
our code or in AMD's.

about the 7.8.1 startup, because the discussion is more appropriate
here. Yes AMD has publically switched from CAL to OpenCl a few years
back, but the CAL files are still apart of the driver. Even the new RX
Vega drivers still has the files included in them. The question is
what are they using them for? I don't believe it is to maintain
backwards compatibility, because AMD is very quick at cutting off
support for anything they consider legacy. I thought that maybe
they were using them as some sort of low level access to the GPU for
Opencl, and to test this I renamed the files and restarted Boinc. Low
and behold, Opencl has been and is working correctly for over 24 hours
now with out the files, so again why are they still apart of the
driver and what are they using them for? Here is a
link to a project on Github for a AMD GPU assembler and disassembler
that uses the CAL and the modifications to get it working on an RX4

run on an AMD GPU that still use a CAL program, the time it might take
to get it working correctly might not be worth it for just the
increase in info. So in fact it might be better to just remove the CAL
detection completely from Boinc reducing its size and startup time.

reports that no ATI library is found. OpenCL is found and works, but
clDeviceInfo does throw the error about not getting the number of SIMD
units, but it does. And Boinc is warning about the Astropulse r2742.cl
not being the correct size. It does this because with the last change
to the file I made, I forgot to change the file size in the
client_state file. (trying to get the Astropulse units to validate,
with the recent batch of test units on SetiBeta, I'm still getting
some inconclusives thrown, but more of them are validating now, but
that's a different problem).
