A bunch of it also looks like x86 specific stuff which has crept in. e.g. PARAVIRT_LAZY_FOO and paravirt_get_lazy_mode() are arch/x86 specific and shouldn't be called from common code (and aren't, AFAICT). ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
[PATH v3 0/2] Add v4l2 subdev driver for S5K4ECGX sensor with embedded SoC ISP
The following 2 patches add driver for S5K4ECGX sensor with embedded ISP SoC, and minor v4l2 control API enhancement. S5K4ECGX is 5M CMOS Image sensor from Samsung Changes since v2: - added GPIO (reset/stby) and regulators - updated I2C read/write, based on s5k6aa datasheet - fixed set_fmt errors - reduced register tables a bit - removed vmalloc Changes since v1: - fixed s_stream(0) when it called twice - changed mutex_X position to be used when strictly necessary - add additional s_power(0) in case that error happens - update more accurate debugging statements - remove dummy else Sangwook Lee (2): v4l: Add factory register values form S5K4ECGX sensor v4l: Add v4l2 subdev driver for S5K4ECGX sensor drivers/media/video/Kconfig |8 + drivers/media/video/Makefile|1 + drivers/media/video/s5k4ecgx.c | 839 ++ drivers/media/video/s5k4ecgx_regs.h | 3105 +++ include/media/s5k4ecgx.h| 39 + 5 files changed, 3992 insertions(+) create mode 100644 drivers/media/video/s5k4ecgx.c create mode 100644 drivers/media/video/s5k4ecgx_regs.h create mode 100644 include/media/s5k4ecgx.h -- 1.7.9.5 ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

Changing QA images to pre-built ones
Hey, Lately we've been producing and using the pre-built images for most of the use cases we have at Linaro. Seems that now that we finally got it working the way we expected, it'd also make sense to move the Ubuntu QA to start using the pre-built images instead of a combination of hwpack + rootfs. A few advantages about using pre-built images: - Single ID for the hwpack + rootfs combination - Less time to download, if you use zsync with a previous image as base - A lot faster to flash, as it'll use the maximum from your SD card into one single shot (dd) We're producing them daily nowadays, so I think we should just go and change the process. You can find all the pre-built images at http://snapshots.linaro.org/precise/pre-built/ Fathi, Paul, would that work for you both? Thanks! -- Ricardo Salveti de Araujo ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
