[PATCH 0/2] Fixes for TBB ARM support

by Steve Capper

This series fixes a couple of problems with the ARM support in libTBB; the build system did not detect ARM correctly and external code that referenced TBB may have had problems building for Thumb state. These patches apply against tbb41_20130516oss, and have been tested under Fedora 18 and Debian Wheezy (with `make test' and `make examples'). Any comments/critique welcome, as I aim to send these patches upstream.

[Query]: Can people post to this mailing list without subscription?

by Viresh Kumar

Hi Guys, I really don't know whom to direct this mail to and hence the wide spread. Problem: When we send a mail to kernel mailing lists with linaro-dev or linaro-kernel in cc, and we get replies to those mails, sometimes the mails from outside people doesn't reach us back on linaro mailing lists. And i hope the reason behind that is those people aren't subscribed to these lists. For me it makes some sense to allow anyone to send mails to this list. Can that request be considered? I believe the idea behind blocking such use is for protecting against spam mails, but these mails/replies are really important and we certainly need them delivered to us. One solution (don't know if its possible) would be to monitor mails from non-subscribers and few people from Linaro can permit them on daily/hourly basis, so that we don't get any spam mails, but that would be a burden. -- viresh

[PATCH] drm/exynos: Add fallback option to get non physically contiguous memory for gem_dumb_create

by Vikas Sajjan

To address the case where physically contiguous memory MAY NOT be a mandatory requirement for framebuffer for the application calling exynos_drm_gem_dumb_create, the patch adds a feature to get non physically contiguous memory for framebuffer, if physically contiguous memory allocation fails and if IOMMU is supported.

Keithp did the tests and has the details of > exactly what he tested. (are we talking 4.7 or 4.8 (or > both) here keith?) I'm not sure what blocked M0. There are a few things suspicious: * Which C library is used? The one gcc-arm-embedded works, and the only one I know works for Cortex-M, is newlib. Other than that, good luck :-( * What is the newlib version, if you are using newlib. There were some patches for M0 when we enabled gcc-arm-embedded. But all of them are in latest newlib mainline now. Overall, sharing a source between arm-linux and arm-none-eabi sounds a good idea, but library can be the road blocker. As bare-metal version should use newlib and linux use glibc, it is not that straight-forward as assumed. Please be aware of this extra burden. Alternative approach is just grab the gcc-arm-embedded 4.8, which will be ready by Q4, and build it for debian. It will be straight forward as it is already built and released by launchpad as debian package and distributed as PPA. Also it will behavior the same as any other gcc-arm-embedded running on other linux distribution and Windows, which have been downloaded 100,000 copies. I'm OK with both approaches but I believe the latter makes more sense. > > > > Also they are gcc 4.7 based whilst Debian is moving to a 4.8 default. > > > > If history is anything to go by there will be a 4.8 release of that > > toolchain sometime in Q4 2013. Yes, 4.8 will be release in Q4 this year.

As I mentioned in another email, everything is at svn://gcc.gnu.org/branches/arm/embedded-4_x-branch/gcc/ChangeLog.arm given that you got correct newlib.

[Call for participation] Bi-Weekly KVM/ARM Technical Sync-up

by Christoffer Dall

Hi all, Linaro is going to host a bi-weekly sync-up call for technical issues on KVM/ARM development. The KVM 32-bit and 64-bit maintainers as well as the QEMU ARM maintainer will typically be on the call. The first call will be held Tuesday August 27th. If you, your organization, or any of your colleagues are interested in attending this call, please reply back to me with: - Your name - Your e-mail address - The capacity in which you are interested (hobbyist, company you represent, ...) We will send out an invite after we have collected all the participants. The calls will be based on an agenda that I will E-mail out to the list the Monday before the call. If we have no items on the agenda, we will not be having the call. Agenda items should be E-mailed to me and/or the kvmarm list before the call, obviously before the Monday prior to the call. We emphasize that this is going to be a technical call for engineers and not a forum to solicit services or discuss business concepts. Best, -Christoffer

Arndale board cannont disable prefetch on

by Dai Yan

Dear All, Actually I have sent a mail previously, but I found more info for my issue. So I am sorry that I that I send mails again, In fact, I found that when I call " MCR p15, 1, %0, c15, c0", 3, I am trapped into unsecured mode. And I think that I have to call secure monitor(SMC) to do prefetch off safely. But I found that I cannot get the public interface to do that. Could someone give me a hand? Platform: 1) linaro ubuntu 13.07 2) arndale board 3) No Virtualization enabled Best Regards Dai Yan

mailing list for cross build issues created

by Matthias Klose

Today the debian-cross(a)lists.debian.org ML was created. The rationale for having such a ML can be found in http://bugs.debian.org/717332. The description for the ML currently is: Discuss cross building of packages and infrastructure for cross-builds The list discusses * How to cross-build packages within Debian * Infrastructure needed to cross-build packages. This may include discussion about additional tags for cross-building, running cross-build daemons, etc. * How to use cross-builds to bootstrap Debian ports. The issue for the creation of this ML explicitly includes topics which affect Ubuntu and other derivatives. So it makes sense for Ubuntu and Linaro developers to subscribe to this ML too. Please avoid cross posting to Ubuntu a and Linaro lists, as people subscribed to debian-cross may not be allowed to post to these lists. Please subscribe to this list if you are interested in cross build issues. Matthias
