is it proper to have "bytes", while scale unit has KB?

eh, does this really even qualify as a "metric"? Seems only a single 
event...

why no scale unit here?

btw, not sure if Arnaldo is ok with you not cc'ing other guys mentioned 
in "performance events subsystem" or "performance events tooling arm64"..

Thanks,

"KB" would shown in metric result, I think users should understand it well.

Yes, actually it needs a single metric. I consult to Will before, there is no way to program it in the kernel. I also don't want users to enter a long
command line, what worst is that users need find out the AXI ID for each master. If we put it in the metric, it is more friendly. Is it reasonable that
a single metric could be regarded as a special metric? Such as "( imx8_ddr0@axid\\-read\\,axi_mask\\=0x0000\\,axi_id\\=0x006d@ ) * 1 * 1".

ok, fine - I don't see a point in being pedantic, and we should try to 
enhance the user experience (like here).

Maybe in future we could consider a different class of event, like this.
