* RUMP_MEMLIMIT works
* allocating memory with PR_NOWAIT will fail immediately if no memory
is available and PR_WAITOK will wait for memory to be available
/stand/arch/vers/kmods works in rump (and that the result is usable ;).
On i386 this "just works". For amd64, due to -mcmodel=kernel,
things are a little more complicated. We must have the entire rump
kernel loaded in the lower 2GB. Currently, this can be done either
by using the non-PIC version for the rump kernel compiled with
-mcmodel=small, or, as njoly pointed out, using netbsd32, which
causes vm_default_addr() to give something in the lower 2GB and
therefore shared libs "magically" getting loaded there. I guess
it would be possible to put a suggested vaddr into the rump kernel
libs and make ld.elf_so map memory from the suggested address if
present ... but that's another show.
Also thanks to tron for access to an amd64 so that I could verify
the test works.
the LDADD variable expansion. To support static linking, ensure
that the common libraries gets tacked on at the end as well (order
matters for static linking), by using a convenience variable and
add it to the end of LDADD.t_modlinkset, as well as when doing the
general LDADD+= setting.
this becomes apparent when linking statically (e.g. as for sun2).
Add an extra instance of -lrump to the library list so that it can be
linked statically as well.
