stolen from the ia64/ia32 code (indeed there was a repocopy), but I've redone the MD parts and added and fixed a few essential syscalls. It is sufficient to run i386 binaries like /bin/ls, /usr/bin/id (dynamic) and p4. The ia64 code has not implemented signal delivery, so I had to do that. Before you say it, yes, this does need to go in a common place. But we're in a freeze at the moment and I didn't want to risk breaking ia64. I will sort this out after the freeze so that the common code is in a common place. On the AMD64 side, this required adding segment selector context switch support and some other support infrastructure. The %fs/%gs etc code is hairy because loading %gs will clobber the kernel's current MSR_GSBASE setting. The segment selectors are not used by the kernel, so they're only changed at context switch time or when changing modes. This still needs to be optimized. Approved by: re (amd64/* blanket) |
