Software

Beware that the code is rough and it may not work on your machine. This code requires an AMD processor with IBS support.

$ git clone https://pdos.csail.mit.edu/dprof/dprof-linux.git
This is the Linux kernel to be used with DProf. The repository is composed of multiple branches; each branch contains changes to make data collection possible. The master branch is a merge of all branches. The .config we use is also available from the mosbench page.
$ git clone https://pdos.csail.mit.edu/dprof/slab_data_profile.git
This module allows DProf to collect IBS samples annotated with type information.
$ git clone https://pdos.csail.mit.edu/dprof/object_flow_profile.git
This module allows DProf to collect the set of instructions that access a particulars kernel object.
$ git clone https://pdos.csail.mit.edu/dprof/dprof.git
This is a set of Ruby scripts to aggregate the collected data.
