[PATCH 2/4, v2] x86: enlightenment for ticket spin locks - Xen implementation
Use the (alternative instructions based) callout hooks to the ticket spinlock code to enlighten ticket locks when running fully virtualized on Xen. Ultimately, this code might also be a candidate to be used when running para-virtualized. Signed-off-by: Jan Beulich <jbeulich(a)novell.com> Cc: Jeremy Fitzhardinge <j... 29 Jun 2010 10:45

[PATCH 3/4, v2] x86: enlightenment for ticket spin locks - eliminate NOPs introduced by first patch
Under the assumption that the nop-s added by the base ticket spinlock enlightenment patch might be considered undesirable (or worse), here is an optional patch to eliminate these nop-s again. This is done through extending the memory operands of the inc instructions used for unlocking ticket locks to the necessary ... 29 Jun 2010 10:45

[PATCH 4/4, v2] x86: enlightenment for ticket spin locks - improve yield behavior on Xen
This optional patch improves yielding behavior in that the acquire function now checks whether the vCPU owning the lock is actually running, yielding immediately if it isn't. The (only) additional overhead this introduces for native execution is the writing of the owning CPU in the lock acquire paths. If this is ... 29 Jun 2010 10:45
