[Xen-devel] [PATCH v2 0/2] xentrace: fix xentrace for smt=0

[Juergen Gross <jgross@xxxxxxxx>]

When hyperthreads are disabled via smt=0 Xen boot parameter xentrace
is no longer working, but crashing the system.

Patch 1 makes the xentrace user tool work on systems when not all
possible cpu ids have an associated trace buffer allocated.

Patch 2 corrects xentrace handling by sizing the control structures
according to the physical cpus instead of taking online cpus into
account only.

Juergen Gross (2):
  xentrace: allow sparse cpu list
  xentrace: handle sparse cpu ids correctly in xen trace buffer handling
