[ANNOUNCE] Xen port to Cortex-A15 / ARMv7 with virt extensions

by Stefano Stabellini

Hi all, a few weeks ago I (and a few others) started hacking on a proof-of-concept hypervisor port to Cortex-A15 which uses and requires ARMv7 virtualization extensions. The intention of this work was to find out how to best support ARM v7+ on Xen. See http://old-list-archives.xen.org/archives/html/xen-arm/2011-09/msg00013.html for more details. I am pleased to announce that significant progress has been made, and that we now have a nascent Xen port for Cortex-A15. The port is based on xen-unstable (HG CS 8d6edc3d26d2) and written from scratch exploiting the latest virtualization, LPAE, GIC and generic timer support in hardware. We started the work less than three months ago, but the port is already capable of booting a Linux 3.0 based virtual machine (dom0) up to a shell prompt on an ARM Architecture Envelope Model, configured to emulate an A15-based Versatile Express. In this context, we wanted to thank ARM for making the model available to us. Now we are looking forward to porting the tools and running multiple guests. The code requires virtualization, LPAE and GIC support and therefore it won't be able to run on anything older than a Cortex-A15. On the other hand, thanks to this, it is very small and easy to read, write and understand. The implementation does not distinguish between PV and HVM guests: there is just one type of guests that would be comparable to Linux PV on HVM in the Xen X86 world, but with no need for Qemu emulation. The code only requires minimal changes to the Linux kernel: just enough to support PV drivers. Even though we are currently targeting Versatile Express and Cortex-A15 we do intend to support other machines and other ARMv7 with virtualization extensions CPUs. We are also looking forward to ARMv8 and 64 bits support. Given that porting Xen to Cortex-A15 could be done with so little code, we believe that the best course of action is to merge it into xen-unstable as quickly as possible. There are still few rough edges to sort out but we should be able to produce a clean and digestible patch series for submission to xen-devel within the next couple of months. I hope to see the first patches going to the list as soon as possible. We would very welcome any contributions, in the form of testing, code reviews and, of course, patches! A git tree is available here: git://xenbits.xen.org/people/sstabellini/xen-unstable.git arm the gitweb url is the following: http://xenbits.xen.org/gitweb/?p=people/sstabellini/xen-unstable.git/.git;a… And here is the full diff: http://xenbits.xen.org/people/sstabellini/diff We want to point out that this effort is in addition to Samsung's ongoing efforts to upstream Xen ARM to xen-unstable. Samsung's XenARM port allows virtualization of Xen on ARM CPUs prior to virtualization extensions and supports traditional PV guests. I would like to thank Tim Deegan and Ian Campbell: if you spend some time reading the history, you'll see that this project wouldn't have been possible in such a short time without great contributions from them. Cheers, Stefano

[PATCH] thermal: Add a new trip type to use cooling device instance number

by Amit Daniel Kachhap

This patch adds a new trip type THERMAL_TRIP_STATE_ACTIVE. This trip behaves same as THERMAL_TRIP_ACTIVE but also passes the cooling device instance number. This helps the cooling device registered as different instances to perform appropriate cooling action decision in the set_cur_state call back function. Also since the trip temperature's are in ascending order so some logic is put in place to skip the un-necessary checks.

cpu_idle?

by Zach Pfeffer

Amit/Mounir, What's your guys plan with cpu_idle for each board? Are you going to try and upstream a solution that will work across all boards? Would you or Mounir be open to filing a BP per board so we can track when cpu_idle will hit each board? Does it make sense to prototype something across each board that we could land in Ubuntu and Android? Adding other people, leads, etc... -- Zach Pfeffer Android Platform Team Lead, 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

[ACTIVITY] OCTO weekly status report - wk47.2011 (20111121-20111125)

by Ilias Biris

Status report in detail in https://wiki.linaro.org/OfficeofCTO/WeeklyReport Last weekly meeting: https://wiki.linaro.org/OfficeofCTO/2011-11-29 Highlights: - ARMHF (also tracked via https://launchpad.net/linaro-octo-armhf Launchpad project) + Debian builds are now churning + Ubuntu ARMHF now happening - there were some problems unearthed (eg https://bugs.launchpad.net/ubuntu/+source/python2.7/+bug/898172) but moving on. Bugs which will appear will be tackled + Bug https://bugs.launchpad.net/offspring/+bug/892240 - offspring does not currently support armhf. This will impede efforts to get armhf benchmarks running on LAVA. The issue is being now tackled by infra, a machine will be set to handle putting together *unsupported* experimental armhf Debian images as a precursor to getting eventually Ubuntu armhf builds supported by offspring. - ARM Server: Preparation work is ongoing, for the roadmap and requirements as well as initial planning for the first steps. A server LEB will also be discussed from next week onwards. - A number of patches sent already to deal with reducing ticks as a way to reduce power consumption. Check patches from http://patches.linaro.org/team/linaro-octo/ - Finally a short account of memory management: + CMA has seen a new version of the patches as result of the discussion on Kernel Summit + there is ongoing work to enable testing of CMA via LAVA + getting dma-buf sharing improved based on the review comments, and also pushing implementation of v4l2 as a user of dmabuf + we have a first implementation of dri2video for nouveau driver, and also coming soon for omap All questions, comments, are welcome, -- Ilias Biris ilias.biris(a)linaro.org Project Manager, Linaro M: +358504839608, IRC: ibiris Skype: ilias_biris Linaro.org│ Open source software for ARM SoCs

2 > make: *** [drivers] Error 2 > ^C[1]+ Exit 2 make V=1 > build.log 2>&1 OK, so the reason why you can't turn -Werror off is because drivers/net/wireless/bcm4329/Makefile adds it again: DHDCFLAGS = -DLINUX -DBCMDRIVER -DBCMDONGLEHOST -DDHDTHREAD -DBCMWPA2 \ -DUNRELEASEDCHIP -Dlinux -DDHD_SDALIGN=64 -DMAX_HDR_READ=64 \ -DDHD_FIRSTREAD=64 -DDHD_GPL -DDHD_SCHED -DBDC -DTOE -DDHD_BCMEVENTS \ -DSHOW_EVENTS -DBCMSDIO -DDHD_GPL -DBCMLXSDMMC -DBCMPLATFORM_BUS \ -Wall -Wstrict-prototypes -Werror -DOOB_INTR_ONLY -DCUSTOMER_HW2 \ -DDHD_USE_STATIC_BUF -DMMC_SDIO_ABORT -DDHD_DEBUG_TRAP -DSOFTAP \ -DEMBEDDED_PLATFORM -DARP_OFFLOAD_SUPPORT -DPKT_FILTER_SUPPORT \ -DGET_CUSTOM_MAC_ENABLE -DSET_RANDOM_MAC_SOFTAP -DCSCAN -DHW_OOB \ -DKEEP_ALIVE -DPNO_SUPPORT \ -Idrivers/net/wireless/bcm4329 -Idrivers/net/wireless/bcm4329/include EXTRA_CFLAGS = $(DHDCFLAGS) Kbuild doesn't allow you to override such things from the top level. Adding -Werror overrides any preceding -Wno-error flag. -Werror really should only be added in subdirectory Makefiles if the code in that directory is super-clean. The exact behaviour of GCC with -Werror *will* change between different compiler versions -- this is not a bug. It explicitly allows GCC to fail to compile code which might be correct. There seems to be no good way to override -Werror in a subdirectory Makefile from higher-level Makefiles. You may be able to remove the error behaviour for individual warnings with -Wno-error=<warning>, but it's not really a good idea to do this at the top level because it will affect the whole kernel. So far as I can see, the warnings/errors you get probably indicate real issues in the code. It doesn't look like a compiler bug, or a problem with Kbuild -- it's just an effect of the way the writers of that subdirectory wrote their Makefile. If you have not already done so, you should check for newer versions of the code which may fix the problems. If there is no newer version, it would be a good idea to fix the source code issues and propose those changes for merging so that the problem gets solved for everyone. You can also simply remove -Werror from DHDCFLAGS in your local build tree. This will allow you to build the kernel, but it won't prevent other people from encountering the same problem. Since this appears to be an issue with an Android kernel tree, I suggest if you have more questions on this you should reply via linaro-dev(a)lists.linaro.org, or ask questions on the #linaro or #linaro-android channels on IRC at chat.freenode.net if you need additional help.
