[PATCH] ARM: EXYNOS4: Setup consistent dma size at boot time

by Tushar Behera

Some of the boards under mach-exynos4 initialize frame-buffers for which the memory requirement is more than 2MB (Nuri board requires around 4MB, Origen requires around 2.6MB), hence the default dma pool allocation size of 2MB is not sufficient. The consistent dma size is hence increased to successfully allocate memory for those boards. Depends on "ARM: Add init_consistent_dma_size()" by Jon Medhurst (99d1717dd7fecf2b10195b0d864323b952b4eba0).

BUGREPORTED work item state

by Fathi Boudra

Hi Zach, I noticed that you introduced BUGREPORTED on Android blueprints for the work items. It raised a couple of questions: 1. what does BUGREPORTED means ? 2. do we need to update https://wiki.linaro.org/Process/WorkItemsHowto#Work_items_in_the_whiteboard ? The whiteboard work items are parsed to update status.linaro.org so I guess these work items are simply skipped. Cheers, -- Fathi Boudra Linaro Release Manager | Validation Project Manager Linaro.org | Open source software for ARM SoCs

Linaro CI hwpack name improvements

by Deepti Kalakeri

Hello, I am working on improving the hwpack names delivered by the Linaro Kernel Continuous Integration. To start on this I needed inputs from the kernel team. currently the hwpack containing the newly built kernel debian package is named for example as hwpack_linaro-panda_20111004-1126_armel_supported.tar.gz and it includes 1) The board on which the hwpack can be booted 2) The hwpack creation timestamp includes the date in yyyymmdd format along with the time in hhmm format. The hwpack name does not include any defconfig related information, which was used to build the kernel. Do we need to use the defconfig name as well to be part of the hwpack name ? Is there any other information you would like to include in the hwpack name ? Or do we need to continue with the current hwpack names ? -- Thanks and Regards, Deepti Infrastructure Team Member, Linaro Platform Teams Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

[Patch 5/11] Regulator: DA9052/53 regulator support v4

by ashishj3

The Dialog PMIC has below featured regulators:- DA9052-BC - 4 DVS Buck converters 0.5V - 3.6V upto 1Amp. DA9053-AA/BX - 4 DVS Buck converters 0.5V - 2.5V upto 3Amp. DA9052/53 - 10 Programmable LDO's High PSSR, 1% accuracy. This patch support all the DA9052 and Da9053 regulators. The output voltages are fully programmable via I2C or SPI interface. The platform data with regulation constraints is passed down from the board to the regulator.

11.10 image changes

by Tom Gall

All, Our oneiric based images and hwpacks are shaping up in advance of the 11.10 based release. Already you can download from http://snapshots.linaro.org/oneiric. Some important things you'll want to be aware of. We'll be upgrading the version of live-build that we use to generate our images very soon. (today? tomorrow?) When we do so, it'll change the format of the root file system tarballs. This unfortunately will also mean you'll need to obtain a latest greatest version of linaro-media-create otherwise linaro-media-create will fail. The change in format of the tarball also means that the rootfs tarballs will appear to be larger. Don't panic. Once installed with linaro-media-create the installed image sizes are close to what they were in natty. The reason for the extra size is live-build is putting a copy of all the installed .debs into the tarball. -- Regards, Tom "We want great men who, when fortune frowns will not be discouraged." - Colonel Henry Knox Linaro.org │ Open source software for ARM SoCs w) tom.gall att linaro.org w) tom_gall att vnet.ibm.com h) tom_gall att mac.com

[PATCH] gpio/samsung: Move SoC specific codes within macro

by Tushar Behera

In drivers/gpio/gpio-samsung.c, there are certain structures and functions which are not getting used if the particular CPU is not selected. These code segments are moved under CPU specific macros to remove compilation warnings. Signed-off-by: Tushar Behera <tushar.behera(a)linaro.org> --- It has been build tested with s3c2410_defconfig, s3c6400_defconfig, s5p64x0_defconfig, s5pc100_defconfig, s5pv210_defconfig and exynos4_defconfig. The patch has been rebased onto Commit: gpio/samsung: correct pin configuration for S5PC100/S5PC110/EXYNOS4 on git://github.com/kgene/linux-samsung.git (next/topic-gpio-samsung) drivers/gpio/gpio-samsung.c | 10 ++++++++++ 1 files changed, 10 insertions(+), 0 deletions(-) diff --git a/drivers/gpio/gpio-samsung.c b/drivers/gpio/gpio-samsung.c index b6be77a..33d62d1 100644 --- a/drivers/gpio/gpio-samsung.c +++ b/drivers/gpio/gpio-samsung.c @@ -318,6 +318,7 @@ static unsigned samsung_gpio_getcfg_4bit(struct samsung_gpio_chip *chip, return S3C_GPIO_SPECIAL(con); } +#ifdef CONFIG_PLAT_S3C24XX /* * s3c24xx_gpio_setcfg_abank - S3C24XX style GPIO configuration (Bank A) * @chip: The gpio chip that is being configured. @@ -379,7 +380,9 @@ static unsigned s3c24xx_gpio_getcfg_abank(struct samsung_gpio_chip *chip, return S3C_GPIO_SFN(con); } +#endif +#if defined(CONFIG_CPU_S5P6440) || defined(CONFIG_CPU_S5P6450) static int s5p64x0_gpio_setcfg_rbank(struct samsung_gpio_chip *chip, unsigned int off, unsigned int cfg) { @@ -417,6 +420,7 @@ static int s5p64x0_gpio_setcfg_rbank(struct samsung_gpio_chip *chip, return 0; } +#endif static void __init samsung_gpiolib_set_cfg(struct samsung_gpio_cfg *chipcfg, int nr_chips) @@ -438,10 +442,12 @@ struct samsung_gpio_cfg s3c24xx_gpiocfg_default = { .get_config = samsung_gpio_getcfg_2bit, }; +#ifdef CONFIG_PLAT_S3C24XX static struct samsung_gpio_cfg s3c24xx_gpiocfg_banka = { .set_config = s3c24xx_gpio_setcfg_abank, .get_config = s3c24xx_gpio_getcfg_abank, }; +#endif static struct samsung_gpio_cfg exynos4_gpio_cfg = { .set_pull = exynos4_gpio_setpull, @@ -450,6 +456,7 @@ static struct samsung_gpio_cfg exynos4_gpio_cfg = { .get_config = samsung_gpio_getcfg_4bit, }; +#if defined(CONFIG_CPU_S5P6440) || defined(CONFIG_CPU_S5P6450) static struct samsung_gpio_cfg s5p64x0_gpio_cfg_rbank = { .cfg_eint = 0x3, .set_config = s5p64x0_gpio_setcfg_rbank, @@ -457,6 +464,7 @@ static struct samsung_gpio_cfg s5p64x0_gpio_cfg_rbank = { .set_pull = samsung_gpio_setpull_updown, .get_pull = samsung_gpio_getpull_updown, }; +#endif static struct samsung_gpio_cfg samsung_gpio_cfgs[] = { { @@ -682,6 +690,7 @@ static int samsung_gpiolib_4bit2_output(struct gpio_chip *chip, return 0; } +#ifdef CONFIG_PLAT_S3C24XX /* The next set of routines are for the case of s3c24xx bank a */ static int s3c24xx_gpiolib_banka_input(struct gpio_chip *chip, unsigned offset) @@ -717,6 +726,7 @@ static int s3c24xx_gpiolib_banka_output(struct gpio_chip *chip, local_irq_restore(flags); return 0; } +#endif /* The next set of routines are for the case of s5p64x0 bank r */ -- 1.7.4.1

Easy crossbuilding of package sets/images

by Wookey

One output from the 11.09 release was a reasonably painless way of cross-building whole images against an archive, which also forms the basis for an auto-crossbuilder. There is a HOWTO (for building linaro-nano images) here: https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/CrossBuildNano (It uses armel as the example, but should work the same for armhf) Summary of process ------------------ Essentially you can generate a cross-building chroot in one command (using multistrap), chroot into that (using schroot), and give the builder (xbuilder-simple) a list of packages to build - either a pre-generated one for an image, or your own. It chunters through and builds them all (using xdeb), and leaving build-logs for each package. Then at the end (from outside the chroot) you cross-generate an image from the debs (using multistrap, but the pile could be input for a different tool if you prefer). ------------------ To make this work usefully against a stable (natty) baseline, updated versions of both tools and packages are in two PPAs at: https://launchpad.net/~linaro-foundations/+archive/cross-build-tools and https://launchpad.net/~linaro-foundations/+archive/cross-alip Caveats ------- This is currently a technology demonstration in so far as some of the packages needed for a nano image don't successfully cross-build, so you can't actually currently cross-build all of it, but that should be fixed quite soon. Anyone who wants to help with that is very welcome. I've filed current status and remaining bugs here: https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/LinaroNanoStatus The autobuilder can actually run just as well using pdebuild-cross as xdeb to do the build-work, but that's not been tested for a while and is not covered in the HOWTO. The existing xbuilder is pretty stupid (that's why it's called xbuilder-simple) and it does not yet fully ensure a clean build environment every time (when using xdeb, it should if using pbuilder-cross), but it does enough to work reasonably well in practice. A more rigorous environment reset is on the list of improvements RSN. Ongoing work ------------ The current focus is on getting the remaining packages cross-building so that the whole process works to completeion without cheating by bringing in pre-built packages from the existing archive (That's a useful way to proceed if you want to use this tech today - just adjust the multistrap config to include the base natty armel/armhf archive too) Once this is completed I'll be setting up a continuously-running autobuilder so that the cross-buildability or otherwise of packages can be more easily discovered and more people can get involved in fixing up packages so that cross-building of larger images becomes realistic. It should be a simple matter of three multistrap config file changes to use this on an oneiric base, but it broke in a painfull mess of bind-mounts of deleted /run dirs when I tried it last week, so I'd hold off that for a little while, and stick with the nice natty-based examples. I'll add destructions to the HOWTO when I've got it going. I hope some of you find this useful, or at least interesting. I could really use some help on fixing up breakage in assorted packages, and this HOWTO makes it easy to set up a consistent build environment, so do give it a try and get stuck in if you'd like to see this working fully sooner rather than later. Reports of success, breakage, miserable failure, or how this almost-but-doesn't-quite address your use case are always welcome of course.

sched: ARM: arch_scale_freq_power

by Vincent Guittot

I work to link the cpu_power of ARM cores to their frequency by using arch_scale_freq_power. It's explained in the kernel that cpu_power is used to distribute load on cpus and a cpu with more cpu_power will pick up more load. The default value is SCHED_POWER_SCALE and I increase the value if I want a cpu to have more load than another one. Is there an advised range for cpu_power value as well as some time scale constraints for updating the cpu_power value ? I'm also wondering why this scheduler feature is currently disable by default ? Regards, Vincent
