9ae4651601 Move some MD declarations from x86/pci/files.pci to x86/conf/files.x86, 
so that Xen can use the former.

Drop Xen's pcib.c in favor of the x86 code and thereby unbreak ichlpcib.

d80637780e xbd_map_align() can be called from interrupt context (though 
xbd_handler()->dk_iodone()->dk_start()->xbd_start()), so don't try
to sleep in uvm_km_alloc().

abec36fc7a split device/softc for ioapic 2008-07-03 15:44:19 +00:00

54745077e8 Remove "struct device" from "struct pic", where it was only real 
for ioapics and faked up for others. Add it to "struct ioapic_softc"
for now, until device/softc get split.
This required all typecasts between "struct pic" and "struct ioapic_softc"
to be replaced, I hope I got them all.
functionally tested on i386, compile-tested on xen, untested on amd64

d491d792fd Remork the C implementation of spllower() in evtchn_do_event(), so that 
callbacks are always called in decreasing IPL order. Although it's not
strictly a bug, it makes the code easier to read, and avoids processing
the whole IPL range several times.

a790b941e6 Make cpu_idle a macro calling a function pointer on x86. 
Select the Xen idle routine for Xen, mwait if supported by the CPU and
it is not AMD and halt otherwise. As reported by Christoph Egger,
AMD Barcelona keeps the CPU in C0 state with MWAIT, contrary to HLT,
which uses C1 and therefore much less power.

46512505a9 Update headers: Welcome Xen 3.2.1 
Important note: This does not break backward-compatibility. It is still possible to run on Xen 3.1.4.
Hint for developers: Use the xen_version hypercall to determine at runtime if a new hypercall will work. Also check the hypercall return code.
Tested by me and bouyer. OK bouyer.

ad2fcdc36d Do not set ioapic_bsp_id in cpu_attach_common(). It's already initialized 
in cpu_attach(), and doing it here will overwrite the cpu_number of the
physical CPU with the one from the virtual CPU (which is always 0).
XXX is ioapic_bsp_id read somewhere ?
