Hi all, I want to debug Dom0 driver when installing XEN SERVER5.6 ISO. The XS5.6 kernel is 2.6.27.42-0.1.1 I downloaded "kdb-v4.4-2.6.27-rc8-common-1.1" and "kdb-v4.4-2.6.27-rc8-x86-1". After patching, kdb configure does not appear. I found the below: # cat arch/x86/Kconfig.debug|grep -A10 KDB config KDB bool "Built-in Kernel Debugger support" depends on DEBUG_KERNEL && !XEN This mean kdb does not support XEN? If yes, how to debug Dom0 driver? Thanks! _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

In "linux-2.6.27.42-0.1.1.xs5.6.0.44.111158/arch/x86/Kconfig.debug" config KDB bool "Built-in Kernel Debugger support" depends on DEBUG_KERNEL && !XEN Why disable XEN? I should use unstable kernel to debug? How to get it? Any suggestion is appreciated.

Not the "boot/xen.gz" When XEN installing with ISO, it first load xen.gz,then load vmlinuz,load my driver to check disk. It hanged at "Checking for existing products...". This is my scsi driver problem. LABEL install KERNEL mboot.c32 APPEND /boot/xen.gz dom0_mem=1024M com1=115200,8n1 console=com1,vga --- /boot/vmlinuz xencons=hvc console=ttyS0,115200 extramodules=my_scsi --- /install.img I got vmlinuz''s kernel source from XS5.6 source ISO image. It already include kdb patch. But it disable XEN to ue kdb. I can need build xen.gdb to debug vmlinuz? I''m a newbie for XEN. Any suggestion is appreciated.

Thanks!http://xenbits.xensource.com/ext/debuggers.hg?file/926cc93296dd/xen/kdb/README is totally independent of kdb patches in linux. It has nothing to do with linux kdb. You''ll not need to kdb patches in linux to use it. It is a xen built-in debugger that will let you debug xen or domains. Take a look at the README. thanks Mukesh _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
