2014-12-08i2c: designware: Fix falling time bindings docDoug Anderson
In (6468276 i2c: designware: make SCL and SDA falling time configurable) new device tree properties were added for setting the falling time of SDA and SCL. The device tree bindings doc had a typo in it: it forgot the "-ns" suffix for both properies in the prose of the bindings. I assume this is a typo because: * The source code includes the "-ns" * The example in the bindings includes the "-ns". Fix the typo.

2014-12-05Input: xpad - update docs to reflect current stateDaniel Dressler
The last time this documentation was accurate was just over 8 years ago. In this time we've added support for two new generations of Xbox console controllers and dozens of third-party controllers. This patch unifies terminology and makes it explicit which model of controller a sentence refers to. It also expands certain sections to address the latest versions of Xbox controllers. Thus this documentation should now be useful to end users and not contain out-right untruths. This is the patch's second revision. Prior versions of this patch altered the driver's TODO list. That change has been pulled out of this documentation update patch. Signed-off-by: Daniel Dressler <danieru.dressler@gmail.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2014-12-04clocksource: arch_timer: Allow the device tree to specify uninitialized ↵Doug Anderson
timer registers Some 32-bit (ARMv7) systems are architected like this: * The firmware doesn't know and doesn't care about hypervisor mode and we don't want to add the complexity of hypervisor there. * The firmware isn't involved in SMP bringup or resume. * The ARCH timer come up with an uninitialized offset (CNTVOFF) between the virtual and physical counters. Each core gets a different random offset. * The device boots in "Secure SVC" mode. * Nothing has touched the reset value of CNTHCTL.PL1PCEN or CNTHCTL.PL1PCTEN (both default to 1 at reset) On systems like the above, it doesn't make sense to use the virtual counter. There's nobody managing the offset and each time a core goes down and comes back up it will get reinitialized to some other random value. This adds an optional property which can inform the kernel of this situation, and firmware is free to remove the property if it is going to initialize the CNTVOFF registers when each CPU comes out of reset. Currently, the best course of action in this case is to use the physical timer, which is why it is important that CNTHCTL hasn't been changed from its reset value and it's a reasonable assumption given that the firmware has never entered HYP mode. Note that it's been said that on ARMv8 systems the firmware and kernel really can't be architected as described above. That means using the physical timer like this really only makes sense for ARMv7 systems.

2014-12-03tracing: Add additional marks to signal very large time deltasByungchul Park
Currently, function graph tracer prints "!" or "+" just before function execution time to signal a function overhead, depending on the time. And some tracers tracing latency also print "!" or "+" just after time to signal overhead, depending on the interval between events. Even it is usually enough to do that, we sometimes need to signal for bigger execution time than 100 micro seconds. For example, I used function graph tracer to detect if there is any case that exit_mm() takes too much time. I did following steps in /sys/kernel/debug/tracing. It was easier to detect very large excution time with patched kernel than with original kernel. $ echo exit_mm > set_graph_function $ echo function_graph > current_tracer $ echo > trace $ cat trace_pipe > $LOGFILE ... (do something and terminate logging) $ grep "\\$" $LOGFILE 3) $ 22082032 us | } /* kernel_map_pages */ 3) $ 22082040 us | } /* free_pages_prepare */ 3) $ 22082113 us | } /* free_hot_cold_page */ 3) $ 22083455 us | } /* free_hot_cold_page_list */ 3) $ 22083895 us | } /* release_pages */ 3) $ 22177873 us | } /* free_pages_and_swap_cache */ 3) $ 22178929 us | } /* unmap_single_vma */ 3) $ 22198885 us | } /* unmap_vmas */ 3) $ 22206949 us | } /* exit_mmap */ 3) $ 22207659 us | } /* mmput */ 3) $ 22207793 us | } /* exit_mm */ And then, it was easy to find out that a schedule-out occured by sub_preempt_count() within kernel_map_pages(). To detect very large function exection time caused by either problematic function implementation or scheduling issues, this patch can be useful.
