[v4,1/4] libcamera: ipa_manager: Create IPA by name

26503 diff mbox series

Currently createIPA() / IPAManager::module() assume that there is a 1:1
relationship between pipeline handlers and IPAs and IPA matching is done
based on matching the pipe to ipaModuleInfo.pipelineName[].

One way to allow using a single IPA with multiple pipelines would be to
allow the IPA to declare itself compatible with more than one pipeline,
turning ipaModuleInfo.pipelineName[] into e.g. a vector. But the way
ipaModuleInfo is loaded as an ELF symbol requires it to be a simple flat
C-struct.

Instead, move the IPA creation procedure to be name-based, introducing
an overload to IPAManager::createIPA(pipe, name, minVer, maxVer)  that
allows to specify the name of the IPA module to match. Pipeline handlers
that wants to use their name as matching criteria can continue doing so
using the already existing createIPA(pipe, minVer, maxVer) overload.

I agree with this change, but I wish that the name could be derived from `T`.
And that is quite easy to do, just adding a

   static constexpr const char *name() { return "..."; }

and then using `T::name()` here works mostly.

But unfortunately the raspberry pi ipa modules are not compatible at the moment
with this approach. I have tried to come up with something, but so for has failed.

Maybe the `name` argument could be kept like this:

   const char *name = T::name()

and then the rpi pipeline handler could be changed to use the specific names. Not
a fan of this in any case.

What is the issue ? That the proxy is the same for v4 and v5 ?

The proxy type is the same, but different names need to be used.
