Does linux-linaro support kernel page size bigger than 4K?

by Xu, Qiang

Hi Linaro I am a software engineer from Qualcomm. I want to know that if Linaro can change its memory page size in kernel ? As my CPU is arm-v7, it supports 4k/64k/1M/16M page size translation, but in my linux kernel whose version is 2.6.38, the page size is always 4K, Do the linux-linaro support different page size in kernel?

armv8 fondation perf

by Phi Debian

Hi All, I find out that building a project (make file and then some .c files) is real slow on the Foundation system. How people do build their own package (project, makefile oriented set of compile) on Foundation armv8 system ? Cheers, Phi

[PATCH v2 RFT 0/2] PM / Hibernate: sysfs resume

by Sebastian Capella

Patchset related to hibernation resume: one enhancement to make the use of an existing file more general and one documentation update. Both patches are based on the 3.11-rc6 tag. This was tested on a Pandaboard with partial hibernation support, and compiled on x86. Further testing is needed on other platforms. Please let me know if you're able to verify this on any other systems. [PATCH 1/2] PM / Hibernate: use name_to_dev_t to parse resume Use name_to_dev_t to parse the /sys/power/resume file making the syntax more flexible. It supports the previous use syntax and additionally can support other formats such as /dev/devicenode and UUID= formats. By changing /sys/debug/resume to accept the same syntax as the resume=device parameter, we can parse the resume=device in the initrd init script and use the resume device directly from the kernel command line. kernel/power/hibernate.c | 18 +++++++++++++----- 1 file changed, 13 insertions(+), 5 deletions(-) [PATCH 2/2] PM / Hibernate: add section for resume options This adds a small section to the swsusp.txt file to address the options for resuming. This comments on the manual resume option which is used when resorting to an initrd or initramfs for resuming. Resuming from late init is discussed later in the document, but it seemed appropriate to list them together. Documentation/power/swsusp.txt | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) Changes in v2: -------------- * Added check for null return of kstrndup in hibernate.c Thanks, Sebastian

embedding html into the wiki

by Mike Turquette

Hi all, I wanted to create a google doc spreadsheet for tracking some team activity and then embed in iframe for that spreadsheet into the team wiki page. I tried adding something like the following: === Project Status === {{{#!html <iframe width='500' height='300' frameborder='0' src='https://docs.google.com/spreadsheet/pub?key=0Ajx9x7R7ZLSidGVWcVI5YzhWVER5ZD…'></iframe> }}} Nothing shows up. I decided to try an easier test: === Project Status === {{{#!html <b>Hello, world!</b> }}} I can see the "Hello, world!" string, but the bold tags were ignored. So is HTML embedding disabled in MoinMoin? Any idea on the best way to proceed? Thanks, Mike

Help: making multi-platform ARM kernels work with CONFIG_DEBUG_LL

by James King

Hi, Has anyone else seen the following problem (or better solved it). I am testing with a multi-platform kernel binary on both a Broadcom board and ARM TC2 - as such I have: CONFIG_ARCH_BCM=y CONFIG_ARCH_VEXPRESS=y I am using some debug features and earlyprintk on the BCM board so have: CONFIG_DEBUG_LL=y CONFIG_EARLY_PRINTK=y and a arch/arm/include/debug/bcm_kona.S which is included by Kconfig.debug. If I put earlyprintk on the cmdline for the Broadcom board it all works fine. If I don't on the Vexpress it hangs at kernel start-up. That should have worked ok, but to make it do so I have to comment out the two putstr lines in decompress_kernel in arch/arm/boot/compressed/misc.c (then everything is fine). Apart from just removing those lines so I no longer get the printout of: "Uncompressing Linux... done, booting the kernel." I can't see an obvious way of fixing this. Has anyone else come across this issue with multi-platform kernels and come up with a solution which keeps the Uncompressing printout - I can't find anything about this on the usual mailing lists. Thanks, James

arm32: How to get a bigger rootf from a pre-built image.

by Phi Debian

Hi Guru's I successfully builf my own kernel abd run it for arm64, I try now to do the same trick with arm32. I need to have a root fs bigger enough to do basic dev in c user code. I choose latest raring-developper for this. DL vexpress-raring_developer_20130826-443.img.gz I can then mount it and extract vmlinuz and initrd then boot it like given on some doc pages qemu-system-arm \ -kernel vmlinuz \ -sd vexp.img \ -M vexpress-a9 \ -cpu cortex-a9 \ -serial stdio \ -m 1024 \ -initrd initrd \ -append 'root=/dev/mmcblk0p2 rw mem=1024M raid=noautodetect console=ttyAMA0,38 400n8 rootwait vmalloc=256MB devtmpfs.mount=0' >From there I got a prompt root@linaro-developer:~# uname -a Linux linaro-developer 3.11.0-1-linaro-vexpress #1ubuntu1~ci+130822051821-Ubuntu SMP Thu Aug 22 05:54:20 UTC 201 armv7l armv7l armv7l GNU/Linux root@linaro-developer:~# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/mmcblk0p2 963288 652056 245084 73% / udev 514152 4 514148 1% /dev tmpfs 103060 172 102888 1% /run none 4 0 4 0% /sys/fs/cgroup none 5120 0 5120 0% /run/lock none 515280 0 515280 0% /run/shm none 102400 0 102400 0% /run/user I need more disc space for doing dev, so I investigated 2 options 1) Make the rootfs bigger I truncate 4G the rootfs.img (rootfs.img is a short for vexpress-raring_developer_20130826-443.img) then I losetup the rootfs.img and use gparted to extend the ext4 partition. Alas next reboot fail, a bit like if /dev/mmcblk0p2 has an hardcoded size... 2) have an extern (user data) disc, and have it mounted So I trucate phi.img 4G, mkfs it, and try to mount it, but I got no idea what /dev to use to mount it, and got no idea what could be given in the qemu runstring to ask for one more disc in the HW description. Later on I would need to boot my own kernel, I tried the build from source path, all goes fine and I can get an Image a uImage etc, so I guess it will be a matter of providing this the vmlinus I get along with the initrd I got from teh rootfs.img, will see how it goes. But for now my problem is really to have more disc space either in rootfs ot in an additional disc. Any help appreciated. Cheers, Phi
