This is correct usage of the __HVC() macro, so

New Gator version
Hi Andrey Two weeks ago ARM released a new version of Developer Studio 5 (v5.12) which as usual included a new version of the Streamline plugin and the corresponding new versions of the Gator daemon and module which run on the target device. I have updated my tracking branch which is pulled into linux-linaro-core-tracking so Linaro's Linux 3.7 kernels will get this new Gator version. However, I suspect that some builds will be staying with Linux 3.6 for a while so I have a separate topic branch suitable for pulling into this. I'm not completely sure how such branches will be managed but, if it is possible, can the Gator version in 3.6 be replaced by the new one from the branch '3.6-armlt-gator-5.12' in ARM LT tree (git://git.linaro.org/landing-teams/working/arm/kernel) ? Thanks -- Tixy ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

Yip.

Yes please. While we're focused on the Cortex-A series, we don't want to harm earlier architectures. If you see any speed or correctness regressions please let us know. -- Michael ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

Or used make savedefconfig? Yes these are added manually, make savedefconfig should be better, but it seems the original defconfig file are not well generated by savedefconfig, this file will be changed too much if I use make savedefconfig. If this is an issue, I will inform the maintainer to update this. After consideration, for this time, I will use savedefconfig to find right places for my configs, discarding the other dis-order ones. ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
