If it is ok, can you please merge these patches
I was about to merge them but I wanted to try first. Enabling kgd tests at boot time, I get plenty of failures as below. Have you successfully run the kgdb tests?
I re-tested v9 version patches with our internal arm64 simulator and I don't see these warnings. Also I tested with 3.13 kernel from linaro with v8 foundation model and no errors are seen (logs below).
It's good to know. Could you please rebase against 3.14-rc3 and rerun the tests? If they work, please send me your .config file that you used with the foundation model.
(and since you rebase on 3.14-rc3, you could repost a v10 with all the acks in place so that it's easier for me to merge)
Reposted v10 version of patches which is rebased on 3.14-rc3 kernel. Test results are as follows on v8 foundation model.
