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🏃u noploop 1
noploop for 1 seconds
3,206,304,898 global_power_events:running
