Initial landing of SMP support for FreeBSD/amd64. - This is heavily derived from John Baldwin's apic/pci cleanup on i386. - I have completely rewritten or drastically cleaned up some other parts. (in particular, bootstrap) - This is still a WIP. It seems that there are some highly bogus bioses on nVidia nForce3-150 boards. I can't stress how broken these boards are. I have a workaround in mind, but right now the Asus SK8N is broken. The Gigabyte K8NPro (nVidia based) is also mind-numbingly hosed. - Most of my testing has been with SCHED_ULE. SCHED_4BSD works. - the apic and acpi components are 'standard'. - If you have an nVidia nForce3-150 board, you are stuck with 'device atpic' in addition, because they somehow managed to forget to connect the 8254 timer to the apic, even though its in the same silicon! ARGH! This directly violates the ACPI spec. 2003-11-17 08:58:16 +00:00			`AUTO_EOI_1 opt_auto_eoi.h`

Sync up with the files in the hammer branch in the p4 tree to get basic AMD64 support. There is still more to add. 2003-05-01 02:59:24 +00:00			`HAMMER opt_cpu.h`

Add BASIC i386 binary support for the amd64 kernel. This is largely 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.
