What do you mean by real-time display? powerdebug will only refresh it's information every 'n' seconds. At that point, the 'show' function for the sysfs rate entry should call get_rate() for the clock. > Actually, this feature can be easily supported. if you found some > clocks' information stay unchanged after your drivers change clock > setting, it may be caused by the wrong way of clock information > exposing. > > In the last several weeks, Jeremy and I reviewed the clock debug code > based on common clock struct.

Why is it called clk_debug_rate_get()? Is there not a standard clk_rate_get() that we can use? > Previously, some of you might use a variable to store clock > information like rate or count, and expose these variable to sysfs, > which is why they are not updated when the real clock information is > changing. Right, storing in variables will give wrong results if you're in the middle of a rate refresh.

Re: [Branch ~linaro-maintainers/linaro-image-tools/linaro-image-tools] Rev 220: Drop parted dependency.

by Guilherme Salgado

Hi Loïc, l-m-c still uses parted, albeit indirectly via media_create/partitions.py, so unless I'm missing something I think this should be reverted.

Minutes & actions: Kernel Working Group meeting of Dec 13th, 2010

by Mounir Bsaibes

Greetings, Enclosed you'll find a link to the agenda, minutes and actions from the Linaro kernel working group weekly meeting of December 13, 2010. https://wiki.linaro.org/WorkingGroups/KernelConsolidation/Meetings/2010-12-…<https://wiki.linaro.org/WorkingGroups/KernelConsolidation/Meetings/2010-11-…> == Summary == * Reviewed Freescale BSP. Many drivers are close to being upstreamable. * eMMC performance improvement, initial numbers shows 5% performance gains for large writes and 10% performance gains for large reads. * USB patches for 8500 have been accepted into Greg KH's tree, and Felipe Balbi's tree. * u-boot is in the final phases of the 2010-12 release. Patch from last week (environment code would incorrectly report correctable errors) accepted in mainline. * Working RTC issues: timer list and timer queue which are precursors to getting the Android alarms upstreamed. Patches in -tip slated for 2.6.38. LWN article for timers and alarms. * Working IRQ code in core code in support of virtual IRQ. Working on QEMU model of Versatile Express and the Nvidia Tegra (Serial port and eMMC). Dusting off u-boot work that John Rigby has done so that device tree is passed correctly to kernel. Kernel configuration management solution in the works -- "Kconfig fragment". Configuration process loads an alternative per-board Kconfig file that sets defaults for Kconfig, and then sets up with the full Kconfig, so that you can have definitions set up for a family of SoCs or boards. * Looked at gitdm tool, considering sending in a patch to list Linaro people as belonging to Linaro instead of to whatever gitdm currently accounts them to. * Finished kexec() blueprint specification, will get it reviewed next. * Progress on RCU priority boosting, additional energy-management tasks and scalability tasks look to be easily handled. Regards, Mounir
