Cover letter [RFC, PATCH 0/4] Add support to OProfile for profiling Cell BE SPUs -- update
On December 14, 2006, I posted a patch that added support to the OProfile kernel driver for profiling Cell SPUs. There have been some changes/fixes to this patch since the original posting (including forward porting from 2.6.18-based kernel to 2.6.20-rc1), so I am reposting the patch for review now. This patch relies upon the following patches that have not been accepted yet:
1. oprofile cleanup patch (submitted on Nov 27)
2. Fix for PPU profiling (not submitted yet, since it depends on #1)
3. SPU task notification patch (last submitted on Jan 26)
For those who may want to apply and build the oprofile SPU support patch, it would be necessary to first apply the above patches. For convenience, I will post all three of the above patches, along with the oprofile SPU support patch.
Comments appreciated.
Thank you.
