[PATCH-Android] Patches to build Android using GCC 4.5/4.6.

by Sachin Kamat

Hi, The next set of patches will help in building Android source code out of the box using Linaro GCC 4.5/4.6 toolchains. The patches basically try to circumvent the build problem caused by stricter GCC 4.5/4.6. These patches are based on remotes/m/linaro_android_2.3.2 branch. Regards, Sachin

[NOTES] Minutes & Actions: Kernel Working Group meetings of March 28, 2011

by Mounir Bsaibes

Enclosed you'll find a link to the agenda, minutes, actions and IRC logs from the Linaro kernel working group weekly meetings of March 28, 2011. https://wiki.linaro.org/WorkingGroups/KernelConsolidation/Meetings/2011-03-… == Summary == * Nico will rebase linaro-2.6.38 the current linaro tree is based on 2.6.38-rc5 * Device Tree * Grant has sent a set of patches to John Rigby & the u-boot list which fixes up some things and enables dt support on most of the platforms we care about. Once those fixes are picked up d t should be enabled by default in the u-boot images produced by Linaro. Have to wait until it hits Nico's tree to complete the testing. Grant is pushing out a tree with the panda/beagle/samsung patches tonight will ask npitre to pull. * Bugs * From the bugs without assignee, the remaining bug without patch is 712175. * The Panda power off is fixed * The imprecise abort on Panda with display is fixed * Arnd posted the fix from Uli for 615974 "Interrupted system call handling" * Actions * 11.11 cycle: Everyone to take a look at the high-level requirements on the kernel from the TSC meeting: https://wiki.linaro.org/TSC/2011-03-16/Kernel, Paul will need to come back to TSC with a response.

Device Tree on ARM status report - Mar 20

by Grant Likely

I had great hopes of doing these status reports once a week; but it turns out to take more effort to get together that I estimated. Here's the status of ARM device tree support as of today. As always, let me know if you have any corrections or additional information. 1 - Latest news --------------- - The last vestiges of of_platform_bus_type are gone from Linus' tree as of the 2.6.39 merge window. Everything should be using platform_device now. - devicetree/arm on git://git.secretlab.ca/git/linux-2.6 has everything needed to turn on basic device tree support for any platform. - Support has been added for Versatile and Tegra in devicetree/arm - Support for Samsung s5pv310 and Freescale mx5 are in devicetree/test - Similarly, u-boot needs to have the CONFIG_OF_LIBFDT and CONFIG_SYS_BOOTMAPSZ defined to turn on device tree support. - I've also got patches that eliminate the need for CONFIG_SYS_BOOTMAPSZ which I'll post shortly, but they're not quite working yet. - I've also got a trivial patch that should enabled CONFIG_OF_LIBFDT on a large set of boards, but it has had pretty much zero testing. :-) - Jason Hui has been making awesome progress on mx5, and some of their patches are in devicetree/test. Hopefully to move over to devicetree/arm soon. - Shawn Guo has also been making good progress on adding the clock bindings to the mx5 support. There are still questions up in the air about the best way to handle clocks though. While all the clocks /can/ be converted to device tree data, there is also value in sharing clock initialization data between DT and non-DT board support. The of_platform_device_prepare() work mentioned below will help with that. It will also be easier to work on the clock support when the common struct clk patch series from Jeremy gets merged. Until then there ends up being a lot of duplication of code. - Lennert has a series of virq patches for ARM patches completed. He is currently working on cleaning them up to get them posted. - Patches posted for of_platform_prepare() which makes it easier for static platform_device registrations to co-exist with device tree data. Patches are currently in devicetree/test, and will move to devicetree/arm shortly. - Basic DT support has been merged into Nicolas' Linaro kernel tree. - DT is also working on Versatile Express, OMAP, and the new Xilinx platform, but I don't have patches for either of those platforms in my tree. - Rob Herring's work on the early dtb mmu maping is mainlined and makes it much nicer to work with dtbs. Next steps: -------------- At this point I'm putting on my Linaro hat. Feel free to tune out past this point if you're not interested how DT support will materialize in the next release. There are a number of very specific tasks that need to be completed for the 11.05 release. The goal is to have basic device tree support turned on and working on all of the platforms supported in the release. There isn't a lot of time to get this pulled together, but all the infrastructure is in places, so most of the work is turning on the configuration options and testing the platforms. For each board, I need an engineer to do the following: 1) Enable CONFIG_OF_LIBFDT and CONFIG_SYS_BOOTMAPSZ against the Linaro u-boot tree. 2) Enable CONFIG_OF and CONFIG_PROC_DEVICETREE in the kernel 3) Add something like the following to the *existing* machine definition. For initial basic support, you don't need to create a separate <soc>-dt.c board support file yet. +static const char *omap4_panda_dt_match[] __initdata = { + "ti,omap4-panda", + NULL +}; + MACHINE_START(OMAP4_PANDA, "OMAP4 Panda board") [...] + .dt_compat = omap4_panda_dt_match, MACHINE_END The string in the match table should be in the form "<vendor>,<board-name>" 4) Add a template .dts file for the board in arch/arm/boot/dts/<board>.dts. The following should be sufficient: /dts-v1/; / { model = "TI OMAP4 PandaBoard"; compatible = "ti,omap4-panda"; #address-cells = <1>; #size-cells = <1>; aliases { }; memory { device_type = "memory"; reg = <0x80000000 0x08000000>; }; chosen { }; }; 5) test it :-) 6) send patches to me for inclusion in the Linaro U-Boot and Kernel trees. I'll collect them to start and ask John and Nicolas to pull them into their trees when they're ready. This is enough for very basic device tree support and I expect it will only take a day or so of effort to get completed. It won't be particularly useful, but it ensures that the infrastructure is enabled and working. Bonus points if you're also able to provide patches that add of_platform_device_probe() and of_platform_bus_populate() calls to the board support so that device nodes get attached to the devices and can be used for attaching things like gpios, spi devices, and i2c devices. This is a nice to have for 11.05, but it isn't a requirement to have it working on all boards. Here is the list of hwpacks that should be supported to the best of my knowledge. Please reply with the hwpacks you can take responsibility for: efikamx igep imx51 omap3-x11-base omap3 overo panda s5pv310 vexpress There are also some specific cross-platform tasks that need some love. Let me know if you can take responsibility for any of these items. - Eliminate CONFIG_SYS_BOOTMAPSZ dependency from U-Boot. I've got a patch series that does this, but it is untested. I'll post the series tomorrow. - Add packaging of .dtb files into linux-image-linaro-* packages. Loic and I discussed putting them under /lib/dtb/`uname -r`/, but thinking about it more, it might make more sense to share the modules directory and use /lib/modules/`uname -r`/dtbs. The dtc tool needed to build the .dtbs is included with the kernel tree. - Add relevant dtb files to boot partition in linaro-image tools - Add boot script which passes dtb as 3rd argument to 'bootm' For purposes of tracking, I'll register bugs for the above items in the Linaro bug tracker tomorrow. Cheers, g. -- Grant Likely, B.Sc., P.Eng. Secret Lab Technologies Ltd.
