xen-ia64-devel
Re: [Xen-ia64-devel] a problem with "performance tuning TAKE 3"
Hi Isaku,
Thank you on your advice on the changeset. The patch worked just
fine(except for the copyright section at 5/10 but that's no big
problem). I am now trying to install it all. My understanding is that
you have to have
CONFIG_XEN_IA64_TLB_TRACK
CONFIG_XEN_IA64_PERVCPU_VHPT
options on. I would like to know how exactly you do that at compile
time. I'd tried adding
CONFIG_XEN_IA64_TLB_TRACK=y
CONFIG_XEN_IA64_PERVCPU_VHPT=y
to the top level makefile and the Rules.mk under xen/arch/ia64
but in either case, it has not worked.
I got the following error in while make world
ld -g -T xen.lds.s -N \
-Map map.out
