Thanks for the patches, I have applied all of them except the first one I've checked the linux-user testsuite 0.3 on master: The message Set unique value to 000120060e38 (000120060e38) is gone now, but `ls -l dummyfile` doesn't list the file yet. Would this be fpu related? If there were missing syscalls or something, I would expect an error/warning message rather than silent failure. Andreas

Richard, just in case you weren't aware and are interested: I was able to make an es40 emulation in qemu good enough to start Linux. I did this work several months ago, so it need revival. At this time the main limitation was the absence of IOMMU abstraction in qemu. Tristan.
