Brad, I have posted a couple of patches on the review board. You should
take a look.
Thanks

The patch that I will put out on the review board will have both the memory
controller and the cache controller stats in the format specified by the
third option.

Thanks for doing this. This has long been a sore spot and it is great that
you are cleaning this up. I know that code is not easy to understand.
I like the last option, though the memBuffer statistics are not that
important to me.
What I care about is the generated controller statistics. That is where I
believe it is important to maintain a condensed format. I assume you're
plan is to tackle those eventually???

Subject: Printing vector statistics
Hi Brad
I am working on moving more of the statistics collected by ruby to gem5'
style. To keep the printing similar to that of ruby, I am considering
adding an option to print vector statistics in gem5 in style different from
the current one. How would like to see the statistics? I can think of the
following three options:
1. Keep the style as is. This means all the data values for index in the
vector are printed on separate lines. For example:
system.ruby.dir_cntrl0.memBuffer.memBankCount::0 19 5.22%
5.22%
# Number of accesses per bank
system.ruby.dir_cntrl0.memBuffer.memBankCount::1 15 4.12%
9.34%
# Number of accesses per bank
system.ruby.dir_cntrl0.memBuffer.memBankCount::2 15 4.12%
13.46%
# Number of accesses per bank
system.ruby.dir_cntrl0.memBuffer.memBankCount::3 19 5.22%
18.68%
# Number of accesses per bank
system.ruby.dir_cntrl0.memBuffer.memBankCount::4 20 5.49%
24.18%
# Number of accesses per bank
The first column is the name of stat and the index in the vector, the
second column is value at the index, the third column is pdf and last one
is pdf.
2. Print the data values, the pdf and the cdf on three separate lines.
Example:
system.ruby.dir_cntrl0.memBuffer.memBankCount::data 19 15 15 19
20
system.ruby.dir_cntrl0.memBuffer.memBankCount::pdf 19% 15% 15%
19%
20%
system.ruby.dir_cntrl0.memBuffer.memBankCount::cdf 19% 34% 49%
68%
88%
3. Print the data values, the pdf and the cdf together on a single line.
Example:
system.ruby.dir_cntrl0.memBuffer.memBankCount::[data, pdf, cdf] [19 5.22%
5.22%] [15 4.12% 9.34%] [15 4.12% 13.46%] [19 5.22% 18.68%] [20 5.49%
24.18%]
