Hi,
There's now amd64 support for rumprun/hw. The main motivation was
making it easier to document the build for newcomers, since now you no
longer need "-- -F ACLFLAGS=-m32" to produce a working system. I guess
some rare folks might want to run piggyprograms as unikernels, but if
not, sticking with 32bit is the sensible thing to do (unless you get a
kick out of wasting memory, of course, I don't judge).
Aaaaanyhooooo,
There are two, hmmh, caveats.
The first is that I completely punted with interrupt routing, so all
peripheral interrupts are squashed to 1 level. I'm not sure this is a
huge problem in a system with typically 1-2 interrupt sources, but if
someone wants to fix it properly, knock yourself out.
The second one is more curious. For whatever reason, tls data does not
get loaded. It's present in the baked binary (verified by hexdump), but
if you examine the contents of the memory location even right at the
kernel entry point before anyone has had a change to stompstomp, the
contents are all zeros. tls/bss works just fine. Needless to say, this
little issue makes the tls test fail. The good news is that it's the
only failing test.
enjoy, or something
