[gPXE-devel] Usermode debugging under Linux patchset

[Piotr Jaroszyński]

Hello,

this patchset adds linux platform which allows developing gPXE directly in
userspace. This means that you don't need a separate dev machine or even a
separate nic to work on gPXE.

It fully supports gdb as well as valgrind (for both malloc() and umalloc()).

Currently there are two linux specific drivers available. First one - tap - is
a very simple driver that uses the tap interface to provide networking to gPXE.
See [1] for a howto.

The second driver - lpci - is really an additional layer that allows developing
all PCI drivers in userspace. It requires an extra kernel module, but I hear
it's worth the hassle ;) A howto is at [2].

A little outdated (from before the lpci driver) implementation details are at [3].

All kind of feedback highly appreciated :)
