[Xen-ia64-devel] [PATCH][RFC]xenperf hypercall pretty print
this patch pretty prints the hypercall section for
$xenperf -f
previously, xenperf -f simply listed counts for all hyper calls. I added
a hypercall index to this so it will be easier to tell which hypercall
was called how many times. this is an architecture independent patch.

Hi Isaku, Your .config file did the trick and the installation went very smoothly. Thank you for your help!

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. Hi Ken. To give these options for xen, use .config under the xen directory. In your case, create xen-ia64-unstable-PATCHED.hg/.config and add the following two lines xen_ia64_tlb_track=y xen_ia64_pervcpu_vhpt=y It is also O.K. to edit Rules.mk. But you should add the above two lines. not CONFIG_XEN_IA64_xxx=y. FYI I use the following xen .config $ cat .config crash_debug=y debug=y verbose=y xen_ia64_tlb_track=y xen_ia64_pervcpu_vhpt=y perfc=y perfc_arrays=n I got the following error in while make world ld -g -T xen.lds.s -N \ -Map map.out linux-xen/head.o /home/ken/xen-ia64-unstable-PATCHED.hg/xen/common/built_in.o /home/ken/xen-ia64-unstable-PATCHED.hg/xen/drivers/built_in.o /home/ken/xen-ia64-unstable-PATCHED.hg/xen/arch/ia64/built_in.o -o /home/ken/xen-ia64-unstable-PATCHED.hg/xen/xen-syms /home/ken/xen-ia64-unstable-PATCHED.hg/xen/arch/ia64/built_in.o(.text +0x2722): In function `arch_domain_create': /home/ken/xen-ia64-unstable-PATCHED.hg/xen/arch/ia64/xen/domain.c:416: undefined reference to `tlb_track_destroy' gcc -O2 -fomit-frame-pointer -DNDEBUG -Wall -Wstrict-prototypes -Wdeclaration-after-statement -D__XEN_TOOLS__ -Werror -I ../../tools/python/xen/lowlevel/xc -I ../../tools/libxc -o xc_shadow xc_shadow.o -L../../tools/libxc -lxenctrl make[4]: *** [/home/ken/xen-ia64-unstable-PATCHED.hg/xen/xen-syms] Error 1 make[4]: Leaving directory `/home/ken/xen-ia64-unstable-PATCHED.hg/xen/arch/ia64' make[3]: *** [/home/ken/xen-ia64-unstable-PATCHED.hg/xen/xen] Error 2 make[3]: Leaving directory `/home/ken/xen-ia64-unstable-PATCHED.hg/xen' make[2]: *** [install] Error 2 make[2]: Leaving directory `/home/ken/xen-ia64-unstable-PATCHED.hg/xen' make[1]: *** [install-xen] Error 2 make[1]: *** Waiting for unfinished jobs Hmm, Anyway this is a compilation bug which depends on configuration.

This is in reference to your patch posted at http://lists.xensource.com/archives/html/xen-ia64-devel/2006-08/msg00149.html I tried to use your patch on the latest Xen-ia64-unstable but failed. my changeset is 11044:42a170218b63 I also tried the 10939 changeset with which you posted 2/10 of your patch, but with no avail also. Can you enlighten me on how to make this patch work? Thank you. Ken Hironaka ___ Xen-ia64-devel mailing list Xen-ia64-devel@lists.xensource.com http://lists.xensource.com/xen-ia64-devel
