Re: [Xen-devel] [PATCH] Improve guest stack traces

Add an option to use the frame pointer for guest stack traces.
For stack dumps, avoid assumptions regarding stack size, and
continue past unreadable addresses, which helps when a guest
has overflowed its stack.

Improved guest backtraces belong in the xenctx utility (tools/xentrace/xenctx.c). It already has the clear advantage that it can print kernel symbols as well as addresses. The stack dump code in Xen is mainly for very early crashes in dom0, and it's quite sufficient for that.

So, if you want a frame-walking mode, put it in xenctx.
