[PATCH v3] ARM: OMAP2+: hwmod: Add a new state to handle hwmods left enabled at init

by Rajendra Nayak

An hwmod with a 'HWMOD_INIT_NO_IDLE' flag set, is left in enabled state by the hwmod framework post the initial setup. Once a real user of the device (a driver) tries to enable it at a later point, the hwmod framework throws a WARN() about the device being already in enabled state. Fix this by introducing a new state '_HWMOD_STATE_ENABLED_AT_INIT' to identify such devices/hwmods. When the device/hwmod is requested to be enabled (the first time) by its driver/user, nothing except the mux-enable and a state change to '_HWMOD_STATE_ENABLED' is needed. The mux data is board specific and is unavailable during initial enable() of the device, done by the framework as part of setup(). A good example of a such a device is an UART used as debug console. The UART module needs to be kept enabled through the boot, until the UART driver takes control of it, for debug prints to appear on the console.

Cross Compiling Firefox with Multiarch

by Riku Voipio

Hi, Just to let you all know, due to the ongoing multiarch work, it is not possible to cross-compile relatively complex packages in ubuntu. For example, following the instructions[1], Firefox. While building on oneiric, patched packages from the linaro-maintainers overlay are needed, many of those patches are on precise, and rest should get there during the next cycle. Cheers, Riku [1] https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/FirefoxCrossCompi…

[PATCH v3 0/5] common clk framework

by Mike Turquette

Hi all, A quick refresher: the clock framework APIs in include/linux/clk.h have allowed platforms to develop their own platform-specific implementations to manage clocks; this meant that everyone had their own definition of struct clk, duplicated much code and contributed negatively to the on-going quest for The One Image to Rule Them All. The common clk framework is an attempt to define a generic struct clk which most platforms can use to build a clk tree and perform a well-defined set of operations against. These five patches are the next iteration of the common clk framework. Since the V2 submission back in late September I ported the OMAP4 portion of OMAP's platform-specific clk framework and actively developed the generic code on a Panda board which revealed many bugs in V2. The patches are based on Linus' v3.2-rc1 tag and can be pulled from: git://git.linaro.org/people/mturquette/linux.git http://git.linaro.org/gitweb?p=people/mturquette/linux.git;a=shortlog;h=ref… A great deal of this work was first done by Jeremy Kerr, who in turn based his patches off of work by Ben Herrenschmidt (https://lkml.org/lkml/2011/5/20/81). Many others contributed to those patches and promptly had their work stolen by me. Thanks to all for their past contributions. What to expect in this version: .the most notable change is the removal of struct clk_hw. This extra layer of abstraction is only necessary if we want hide the definition of struct clk from platform code. Many developers expressed the need to know some details of the generic struct clk in the platform layer, and rightly so. Now struct clk is defined in include/linux/clk.h, protected by #ifdef CONFIG_GENERIC_CLK. .flags have been introduced to struct clk, with several of them defined and used in the common code. These flags protect against changing clk rates or switching the clk parent while that clk is enabled; another flag is used to signal to clk_set_rate that it should ask the parent to change it's rate too. .speaking of which, clk_set_rate has been overhauled and is now recursive. *collective groan*. clk_set_rate is still simple for the common case of simply setting a single clk's rate. But if your clk has the CLK_PARENT_SET_RATE flag and the .round_rate callback recommends changing the parent rate, then clk_set_rate will recurse upwards to the parent and try it all over again. In the event of a failure everything unwinds and all the clks go out for drinks. .clk_register has been replaced by clk_init, which does NOT allocate memory for you. Platforms should allocate their own clk_hw_whatever structure which contains struct clk. clk_init is still necessary to initialize struct clk internals. clk_init also accepts struct device *dev as an argument, but does nothing with it. This is in anticipation of device tree support. .Documentation! I'm sure somebody reads it. .sysfs support. Visualize your clk tree at /sys/clk! Where would be a better place to put the clk tree besides the root of /sys/? When a consensus on this is reached I'll submit the proper changes to Documentation/ABI/testing/. What's missing? .per tree locking. I implemented this at the Linaro Connect conference but the implementation was unpopular, so it didn't make the cut. There needs to be better understanding of everyone's needs for this to work. .rate change notifications. I simply didn't want to delay getting these patches to the list any longer, so the notifiers didn't make it in. I'll submit them to the list soon, or roll them into the V4 patchset. There are comments in the clk API definitions for where PRECHANGE, POSTCHANGE and ABORT propagation will go. .basic mux clk, divider and dummy clk implementations. I think others have some code lying around to implement these, so I left them out. .device tree support. I haven't looked much at the on-going discussions on the dt clk bindings. How compatible (or not) are the device tree clk bindings and the way these patches want to initialize clks? .what is the overlap between common clk and clkdev? We're essentially tracking the clks in two places (common clk's tree and clkdevs's list), which feels a bit wasteful. What else? .OMAP4 support will be posted to LOML and LAKML in a separate patchset, since others might be interested in seeing a full port. It is a total hack, and is not ready for a formal submission.

Bus framework

by Richard Zhao

Hi Amit, Is there anyone working on a SoC bus framework? The bus framework can manage the bus fabric, ddr, OCRAM clocks. When a device driver become working, it tells bus framework, cpu may access me (ip bus and related bus fabric on), I'm also a bus master, may access ddr (ddr dma access +1 ). For bus framework, if ddr dma access request is zero, ddr clk can be disabled in WFI/wait mode. The bus framework manage the SoC bus topology. If a bus switch use count is zero, it can be disabled. It may even adjust the bus freq dynamically according to bus request. Thanks Richard

For the device tree topic, is there anything I can do in the 11.12 (28th November 2011 - 18th November 2011)?

by Botao Sun

Hi Angus & Grant, Because the Linaro Android 11.11 release has been done successfully, I have some time to continue to work on device tree topic, here is my blue print for it: https://blueprints.launchpad.net/linaro-android/+spec/linaro-android-origen… Therefore, I would like to know what I can do for this in the 11.12 cycle - from now to the 18th December 2011. For Samsung Origen Android build, the latest kernel version I got is still 3.0.4+, so I think there is no any device tree stuff in it. @Angus, Would you give me a brief about the device tree support status on our current 3.0.4+ kernel? Will you upgrade it to the 3.1 in 11.12 cycle? @Thomas, In this blue print: https://blueprints.launchpad.net/linaro-android/+spec/linaro-platforms-lc4.…, Tony mentioned that you has upstreamed the initial support for device tree. However, it depends on the 3.1 kernel upgrade. I would like to know that is there any possible that I can do something without the kernel upgrade? I currently feel that this work highly depends on the outcome of landing team and kernel group, so before I get something from them, I'm afraid that I can't do any "real" work on this. Thank you all for your help! BR Botao Sun

[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

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
