Hi,
just booting XEN0 (from netbsd-3 src) I see there is no ACPI nor
CardBus support. As I have a laptop with bad APM issues and atheros
wifi cardbus for connection, I feel a bit disapointed ;)
I tried to take my NetBSD kernel and add the diffs from GENERIC vs
XEN0 but this does not work. First try said :
ATHERIA.XEN0:262: ioapic*: unknown device `ioapic'
ATHERIA.XEN0:290: acpi0: unknown device `acpi'
ATHERIA.XEN0:297: acpiacad*: unknown device `acpiacad'
ATHERIA.XEN0:298: acpibat*: unknown device `acpibat'
ATHERIA.XEN0:299: acpibut*: unknown device `acpibut'
ATHERIA.XEN0:300: acpiec*: unknown device `acpiec'
ATHERIA.XEN0:301: acpilid*: unknown device `acpilid'
ATHERIA.XEN0:302: acpitz*: unknown device `acpitz'
ATHERIA.XEN0:305: com* at acpi?: `acpi' unknown
... blabla
Then I uncommented "include "arch/i386/conf/std.i386"" and got :
../../../../arch/xen/conf/std.xen:6: syntax error
../../../../arch/xen/conf/std.xen:8: already have options `EXEC_AOUT=1'
../../../../arch/xen/conf/std.xen:9: already have options `EXEC_ELF32=1'
../../../../arch/xen/conf/std.xen:10: already have options `EXEC_SCRIPT=1'
../../../../arch/xen/conf/std.xen:12: already have options `INET6_MD_CKSUM=1'
ATHERIA.XEN0:1225: hypervisor*: unknown device `hypervisor'
... blabla
The diff between NetBSD and Xen kernel are :
-(ptijo@atheria)-(NetBSD 3.0_BETA)-(0 jobs)-(Sat May 07)-
-(17:58)-(/usr/src/sys/arch/i386/conf)- diff -u2 ATHERIA ATHERIA.XEN0

So,
1. is there ACPI and/or cardbus support on Xen (domain0) ?
2. how to build a kernel with support for this ?
3. better add NetBSD drivers ref to XEN0 kernel template or the contrary ?
TIA,
Jo
