Re: Performance enabling of Event handler

["Bi, Dandan" <dandan.bi@intel.com>]

Hi,

DP tool will filter some entries in which the time duration < 1ms by default.
And you can  use the" dp -t 0  "to dump all the Perf entries.
Then to double check whether the entry you care exists or not.


Thanks,
Dandan

Hi 

Yes it is included in same module (both event handler and function handler), and I’m not perf_start and perf_end only two times (one is by event handler and one is by normal function handler).

And I’m trying to print result using DP.efi, it shows entry for normal function.

Event is created successfully and event handler is also called successfully, but I can capture the performance of this event handler with PerformancePkg (by using perf_start and perf_end check points). This PerformancePkg is working fine with normal function calls.
