[PATCH V4 0/8] driver/core: cpu: initialize opp table

by Viresh Kumar

Drivers expecting CPU's OPPs from device tree initialize OPP table themselves by calling of_init_opp_table() and there is nothing driver specific in that. They all do it in the same redundant way. It would be better if we can get rid of redundancy by initializing CPU OPPs from CPU core code for all CPUs (that have a "operating-points" property defined in their node). This patchset callsl of_init_opp_table() directly from register_cpu() right after CPU device is registered. Later patches updates existing cpufreq drivers which were calling of_init_opp_table() directly. V3->V4: - Remove of_init_cpu_opp_table() and use of_init_opp_table() instead after adding more print messages to it. - Drop a rather unrelated patch which was getting rid of dependency on thermal for cpufreq-cpu0. Will be sent separately.

[patch added to the 3.12 stable tree] hrtimer: Set expiry time before switch_hrtimer_base()

by Jiri Slaby

From: Viresh Kumar <viresh.kumar(a)linaro.org> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== commit 84ea7fe37908254c3bd90910921f6e1045c1747a upstream. switch_hrtimer_base() calls hrtimer_check_target() which ensures that we do not migrate a timer to a remote cpu if the timer expires before the current programmed expiry time on that remote cpu. But __hrtimer_start_range_ns() calls switch_hrtimer_base() before the new expiry time is set. So the sanity check in hrtimer_check_target() is operating on stale or even uninitialized data. Update expiry time before calling switch_hrtimer_base().

[PATCH V2 1/2] sched: idle: Encapsulate the code to compile it out

by Daniel Lezcano

Encapsulate the large portion of cpuidle_idle_call inside another function so when CONFIG_CPU_IDLE=n, the code will be compiled out. Also that is benefitial for the clarity of the code as it removes a nested indentation level.

[PATCH V5 0/2] cpufreq: add support for intermediate (stable) frequencies

by Viresh Kumar

Douglas Anderson, recently pointed out an interesting problem due to which udelay() was expiring earlier than it should. While transitioning between frequencies few platforms may temporarily switch to a stable frequency, waiting for the main PLL to stabilize. For example: When we transition between very low frequencies on exynos, like between 200MHz and 300MHz, we may temporarily switch to a PLL running at 800MHz. No CPUFREQ notification is sent for that. That means there's a period of time when we're running at 800MHz but loops_per_jiffy is calibrated at between 200MHz and 300MHz. And so udelay behaves badly. To get this fixed in a generic way, lets introduce another set of callbacks get_intermediate() and target_intermediate(), only for drivers with target_index() and CPUFREQ_ASYNC_NOTIFICATION unset. get_intermediate() should return a stable intermediate frequency platform wants to switch to, and target_intermediate() should set CPU to to that frequency, before jumping to the frequency corresponding to 'index'. Core will take care of sending notifications and driver doesn't have to handle them in target_intermediate() or target_index(). This patchset also update Tegra to use this new infrastructure and is already tested by Stephen. V4->V5: - Moved setting old frequency to __target_index() from __target_intermediate() - Replaced retval with 0 during call to cpufreq_freq_transition_end() for restoring to restored freq. - Fix important issues with Tegra driver as reported by Stephen. - Dropped patch 1, already applied: "cpufreq: handle calls to ->target_index() in separate routine" V3->V4: - Allow get_intermediate() to return zero when we don't need to switch to intermediate first - Get rid of 'goto' and create another routine for handling intermediate freqs - Allow target_index() to fail, its not a crime :) - Fix tegra driver to return zero from get_intermediate() for few situations (refer to patch 3/4) - Fix issues with tegra's patch, like s/rate/rate * 1000 - Overall there are more modifications that what Doug requested as I felt we need better support from core. - Looks much better now, thanks Doug :) V2-V3: - Fix spelling error: s/Uset/Used - Update tegra with the changes Stephen suggested - Include a dependency patch sent separately earlier (3/4) V1-V2: Almost changed completely, V1 was here: https://lkml.org/lkml/2014/5/15/40 Viresh Kumar (2): cpufreq: add support for intermediate (stable) frequencies cpufreq: Tegra: implement intermediate frequency callbacks Documentation/cpu-freq/cpu-drivers.txt | 29 +++++++++- drivers/cpufreq/cpufreq.c | 67 ++++++++++++++++++++--- drivers/cpufreq/tegra-cpufreq.c | 97 ++++++++++++++++++++++------------ include/linux/cpufreq.h | 25 +++++++++ 4 files changed, 174 insertions(+), 44 deletions(-) -- 2.0.0.rc2

Re: USB serial in ubuntu for arndale

by Botao Sun

Hi Alexandru, No, I'm afraid not that stable but this one: https://git.linaro.org/kernel/linux-linaro-tracking.git There is a wiki page for that Linaro Kernel tree process: https://wiki.linaro.org/Platform/DevPlatform/LinuxLinaroKernelTreeProcess I added Andrey Konovalov to CC list since he currently is the maintainer of linux-linaro kernel and hopefully can provide you more information. Thanks. On 6 June 2014 00:17, Alexandru Rosca <srosca(a)bu.edu> wrote: > Hi Botao, > > Thanks for your help. I am using Ubuntu trusty 14.05.
