x86: consolidate header guards 2008-07-22T19:31:34+00:00 Vegard Nossum vegard.nossum@gmail.com 2008-06-18T15:08:48+00:00 77ef50a522717fa040636ee1017179ceba12ff62 This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>

x86, ptrace: PEBS support 2008-05-12T19:27:53+00:00 Markus Metzger markus.t.metzger@intel.com 2008-04-08T09:01:58+00:00 93fa7636dfdc059b25df148f230c0991096afdef Polish the ds.h interface and add support for PEBS. Ds.c is meant to be the resource allocator for per-thread and per-cpu BTS and PEBS recording. It is used by ptrace/utrace to provide execution tracing of debugged tasks. It will be used by profilers (e.g. perfmon2). It may be used by kernel debuggers to provide a kernel execution trace. Changes in detail: - guard DS and ptrace by CONFIG macros - separate DS and BTS more clearly - simplify field accesses - add functions to manage PEBS buffers - add simple protection/allocation mechanism - added support for Atom Opens: - buffer overflow handling Currently, only circular buffers are supported. This is all we need for debugging. Profilers would want an overflow notification.
