perf: Fix Pentium4 raw event validation
This patch fixes some issues with raw event validation on Pentium 4 (Netburst) based processors. As I was testing libpfm4 Netburst support, I ran into two problems in the p4_validate_raw_event() function: - the shared field must be checked ONLY when HT is on - the binding to ESCR register was missing The second item was causing raw events to not be encoded correctly compared to generic PMU events. With this patch, I can now pass Netburst events to libpfm4 examples and get meaningful results: $ task -e global_power_events:running:u noploop 1 noploop for 1 seconds 3,206,304,898 global_power_events:running Signed-off-by: Stephane Eranian <eranian@google.com> Acked-by: Cyrill Gorcunov <gorcunov@openvz.org> Cc: peterz@infradead.org Cc: paulus@samba.org Cc: davem@davemloft.net Cc: fweisbec@gmail.com Cc: perfmon2-devel@lists.sf.net Cc: eranian@gmail.com Cc: robert.richter@amd.com Cc: acme@redhat.com Cc: gorcunov@gmail.com Cc: ming.m.lin@intel.com LKML-Reference: <4d3efb2f.1252d80a.1a80.ffffc83f@mx.google.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
