Re: GSoC Proposal

i was replying via the groups.io web interface, I'm guessing that messed up
the thread? i haven't used mailing lists before and don't know how they
work. I'll use my mail client from here on.

I'm on board with not treating EFI as an operating system. the more i think
about it the more it looks like scope creep. I'm not quite as enthusiastic
about it as i was at first glance.

I'm still keen on doing my gsoc proposal for edk, though, and even if this
task and the acpica application are decided to be out of scope unit
testing, clang integration and source-level debugging are all relevant to
my interests.

how about your ideas for security stuff? I'm not very knowledgeable about
trusted platform or secure boot but I'm willing to learn whatever is
necessary to get something spun up for my proposal.

Hi, Marvin

Its similarity to my own latest experiment is the key to what grabbed my
attention. I have no particular use case in mind for it, but I see its
potential for anybody developing larger applications in that when a library
is changed there's no need to distribute a new version of the whole binary,
just the relevant library module.

I really do not like the trend of treating UEFI as a full-fledged OS - it
is not. The most used UEFI applications, OS loaders, are really not that
huge and are distributed as part of the OS image anyway. Even for less used
applications, you will always get a full snapshot anyhow. Gladly we don’t
have auto-update and package management yet. :)


I slept on it and it occurred to me that the whole thing could operate
similarly to the shell protocol in that the linker/loader is itself an
application that does a LoadImage() on the application needing dynamic
linking facilities.

That would mean the linker itself is shipped with every application that
requires it? Otherwise it doesn’t make much sense for it to be an app and
below’s problems apply.

If however the whole plan is making the linker as a DXE and including it
with the firmware, that I'm not quite as sure about. That would necessarily
tie any applications using dynamic linking to TianoCore or any firmware
distribution that derives from it.

I think that was the idea referred to as “edk2 core” by Steven, but I’d
like to hear his proposal to be sure. Virtually everyone uses edk2, so that
itself is not the problem, but versioning is. Vendors are slow to update
their snapshots or have just given up doing that entirely. Distributing it
for external applications like OS loaders would mean this can be leveraged
probably no earlier than 10 years from now. And for in-firmware things, I
have a hard time thinking about a use-case that outweighs the drawbacks.


To shift the topic slightly back to GSoC, however, I'm willing to work
on other items on the task list. Unit testing and an ACPICA application are
the alternative projects I had thought about. I need to choose fairly soon
as the proposal deadline is next Tuesday. I know a tiny bit about porting
ACPICA as I also have plans to incorporate it into my own project.

I have a few more ideas for security stuff, but Nate did not confirm them
as appropriate yet and I’m not here to drive you away from this specific
task (or the others). However, I’m still curious and concerned. :)

Best regards,
Marvin
