Why not "tristate"? This driver can be a loadable module, right?
As I understand, modular efivars have still not been fully sorted out in
the kernel. For example, userspace could try and mount efivarfs before
the module has been loaded and by that erroneously determine that the
system doesn't support efivars. So requiring it to be built in for now
is more of a workaround (which has been suggested by Johan Hovold).
There is no technical limitation in this part of the code itself, so
enabling it (and QCOM_QSEECOM for that matter) to be built as module
should be fairly straightforward once that's been sorted out.
If not this application I would atleast like the QSEECOM driver to be a loadable module due to GKI (Generic Kernel Image) needs. Can we mark QSEECOM as "tristate" please? If not then there is a problem which we are not solving right now as you are documenting above and just moving it it for future and downstream vendors will keep having their additional changes to make it fit for loadable module needs.
Could you elaborate a bit on why/how switching to a tristate would help
here? I'm afraid I don't quite follow. Do you mean that this would make
it easier for downstream vendors to patch the module as opposed to
create their own new thing? IMHO if they already need to patch it they
can just as well modify it to be buildable as a module.
Generally I'm not opposed to have both loadable as modules, but I don't
quite see the point as it would not be usable as such in upstream at
the moment (at least not reliably, so to avoid those headaches I think
it's better to just stick to bool for now).
