V2:
a.Update DxecorePerformanceLib/SmmCorePerformanceLib to report the
boot performance table address instead of records contents.
b.Update FirmwarePerformanceDxe/FirmwarePerformanceSmm to receive the address
of performance records.

This patch series also can be accessed at:
https://github.com/dandanbi/edk2/tree/NewPerformanceInfrastructureV2

These patches are to update EDKII performance infrastructure to log and dump
the performance entry as FPDT record in ACPI FPDT table.This new infrastructure
can support to dump performance data in UEFI Shell and OS both.
(1)PeiPerformanceLib/DxeCorePerformanceLib/SmmCorePerformanceLib log the
performance entry as FPDT record.
(2)FirmwarePerformancePei/FirmwarePerformanceDxe/FirmwarePerformanceSmm
install the FPDT records to the ACPI table.
(3)Update DP to dump the performance info from the FPDT records in
FPDT table.

Hi, Dandan

I have seen an email named “ [edk2] [PATCH v2 8/8] ShellPkg/Dp: Updated to dump perf log based on FPDT table “ in mail-archive ” and I know there is an update of Dp.

But I feel uncertain that:

-  // Determine in which direction the performance counter counts. -  TimerInfo.CountUp = (BOOLEAN) (TimerInfo.EndCount >= TimerInfo.StartCount); +  TimerInfo.StartCount = 0; +  TimerInfo.EndCount   = 0xFFFF; +  TimerInfo.CountUp = TRUE;

So it looks like we would not use timer count down feature , does it mean we should use count up timer such as TSC or ACPI Timer? Maybe is there any other cause?

I am looking forward your reply! Thanks!
