<luckyluke>I see syscalls on gnumach are sometimes "converted" into a trap, i.e. when syscall num is out of range, or when a parameter can't be read from the stack because of a page fault
<luckyluke>I wonder why the syscall just don't return a failure code, e.g. KERN_INVALID_ARGUMENT... is this also expected by glibc?
<luckyluke>well, at least for the wrong syscall num... the other case would probably fault again on return, it looks like some form of register corruption...
<gnucode>luckyluke: are you invovled with the libre gpu project?
<luckyluke>gnucode: no
<gnucode>hmm. I thought I recognized your irc nick. nevermind.
