[Qemu-devel] [PATCH v7 00/74] linux-user: Split do_syscall

[Richard Henderson]

Based-on: <address@hidden>
Aka "linux-user: path, clone, sparc, shmat fixes"

Version 6 was
https://lists.gnu.org/archive/html/qemu-devel/2019-01/msg04794.html

Since v5, I've fixed the ioctl failure that Laurent found, and
have done a few more syscalls.

I've tried to do more testing with LTP, but it's a really annoying
testsuite.  There are at least 3 tests that hang forever (before 
and after this patch set), and the host kernel's OOM handler kills
my login session, ending the test run.  This seems to be different
behaviour than I was seeing in January, when I did have test runs
that completed successfully.

OTOH, looking back at the v6 cover letter, I now see that I was
testing armhf and i386 as guests, whereas this time I was trying
aarch64 and ppc64 as guests.  32-bit guests unable to trigger the
host OOM killer?

Laurent, is there anything special that you're doing to see these
tests run to completion?
