From: Mark Brown <broonie(a)linaro.org> Another spin of the arm64 topology work - this should incorporate most of the feedback from Lorenzo, there's a few things that were still under discussion the main ones being: - Should we have a smp_store_cpu_info(); like I say I like the errors it generates for omitted cores and the reuse of the SMP enumeration code (and cross-check with that I guess - make sure we don't get confused about which CPUs are getting enabled). - Should we update the binding to allow cores in the root cpu_map node (since it's less effort in code and not a meaningful difference semantically), warn if we find cores in the cpu_map node or actively reject such DTs? In both cases I don't much mind but I think what's there is reasonable so I've left the code as-is pending further feedback. I also didn't update the code to get more reuse of the iteration code, like I said I did look at that when writing the code but couldn't find anything that actually made things more pleasant but if someone has some ideas... Everything else raised should be addressed I think.

Arndale Timer Interrupt Question

by Mj Embd

Hi Tushar / Samsung, I am a bit confused on the interrupt number for CNTVIRQ..CNTHPIRQ. Can you please help here. As per the exynos5 public manual What is the difference between CPU_nCNTHPIRQ[0] and CNTHPIRQ. While the later has an interrupt ID 26, the former is part of a group with combined interrupt id as 33 for core 0 and 54 for core 1. For a timer interrupt which goes to PL2, which id should be used 26 or 33 for core 0 ? Please clear this confusion. Many Thanks

[Query]: trace-cmd crashing with '-e syscalls' on 3.13-rc1

Hi Steven, I am trying to trace some stuff on Samsung's Arndale Board (ARM) with 3.13-rc1 and seeing these crashes/segmentation faults whenever I try to trace syscalls. Is this a know issue?

[PATCH Resend 1/4] cpufreq: stats: handle cpufreq_unregister_driver() and suspend/resume properly

by Viresh Kumar

There are several problems cpufreq stats in the way it handles cpufreq_unregister_driver() and suspend/resume.. - We must not loose data collected so far when suspend/resume happens and so stats directories must not be removed/allocated during these operations, Which is done currently. - cpufreq_stat has registered notifiers with both cpufreq and hotplug. It adds sysfs stats directory with a cpufreq notifier: CPUFREQ_NOTIFY and removes this directory with a notifier from hotplug core. In case cpufreq_unregister_driver() is called (on rmmod cpufreq driver), stats directories per cpu aren't removed as CPUs are still online. The only call cpufreq_stats gets is cpufreq_stats_update_policy_cpu for all CPUs except the last of each policy. And pointer to stat information is stored in the entry for last cpu in per-cpu cpufreq_stats_table. But policy structure would be freed inside cpufreq core and so that will result in memory leak inside cpufreq stats (as we are never freeing memory for stats). Now if we again insert the module cpufreq_register_driver() will be called and we will again allocate stats data and put it on for first cpu of every policy. In case we only have a single cpu per policy we will return with a error from cpufreq_stats_create_table() due to below code: if (per_cpu(cpufreq_stats_table, cpu)) return -EBUSY; And so probably cpufreq stats directory would show up anymore (as it was added inside last policies->kobj which doesn't exist anymore). I haven't tested it though. Also the values in stats files wouldn't be refreshed as we are using the earlier stats structure. - CPUFREQ_NOTIFY is called from cpufreq_set_policy() which is called for scenarios where we don't really want cpufreq_stat_notifier_policy() to get called. For example whenever we are changing anything related to a policy: min/max/current freq, etc.. cpufreq_set_policy() is called and so cpufreq stats is notified. Where we don't do any useful stuff other than simply returning with -EBUSY from cpufreq_stats_create_table(). And so this isn't the right notifier that cpufreq stats.. Due to all above reasons this patch does following changes: - Add new notifiers CPUFREQ_CREATE_POLICY and CPUFREQ_REMOVE_POLICY, which are only called when policy is created/destroyed. They aren't called for suspend/resume paths.. - Use these notifiers in cpufreq_stat_notifier_policy() to create/destory stats sysfs entries. And so cpufreq_unregister_driver() or suspend/resume shouldn't be a problem for cpufreq_stats. - Return early from cpufreq_stat_cpu_callback() for suspend/resume sequence, so that we don't free stats structure.

Possible arm64 patches for stable

by Mark Brown

Hi, While reading the kernel logs for arm64 (as one does) I noticed a few patches that seemed like candidates for either LTS or LTSI. I've also had a couple of others mentioned via other routes. What do you think of these? 4ecf7ccb1973 arm64: spinlock: retry trylock operation if strex fails on free lock This seems like a correctness fix for spinlocks, though since the callers should cope with failure it's arguably just an optimisation. 53ae3acd4390 arm64: Only enable local interrupts after the CPU is marked online 82b2f495fba3 arm64: virt: ensure visibility of __boot_cpu_mode 845ad05ec31e arm64: Change kernel stack size to 16K 6db83cea1c97 arm64: fix possible invalid FPSIMD initialization state 7b22c03536a5 arm64: check for number of arguments in syscall_get/set_arguments() df503ba7f653 arm64: dts: Reserve the memory used for secondary CPU release address These all look like correctness fixes of one kind or another; the change to 16K stacks is poorly explained but it looks like it's fixing failures of some kind. f0dd718090ae arm64: Remove unused cpu_name ascii in arch/arm64/mm/proc.S A user was reporting that this caused build failures due to alignment issues with some of the debug options turned on. I've not fully investigated yet, this might be a toolchain issue though given how simple the change is. 0d651e4e65e9 clocksource: arch_timer: use virtual counters This is as mentioned in the changelog a correctness fix for avoiding clocks going backwards and has also been found to be required to avoid boot hangs with CONFIG_PROVE_RCU_DELAY enabled. There were also a few others that aren't entirely -stable material but might be a fit for LTSI (and the above might be if not -stable in themselves): b5b6c9e9149d arm64: Avoid cache flushing in flush_dcache_page() 7249b79f6b4c arm64: Do not flush the D-cache for anonymous pages 4f00130b70e5 arm64: Use Normal NonCacheable memory for writecombine These look like simple, localised optimisations. Thanks, Mark
