This patch set enables kdump (crash dump kernel) support on arm64 on top of Geoff's kexec patchset. In this version, there are some arm64-specific usage/constraints: 1) "mem=" boot parameter must be specified on crash dump kernel if the system starts on uefi. 2) Kvm will not be enabled on crash dump kernel even if configured See commit messages and Documentation/kdump/kdump.txt for details. The only concern I have is whether or not we can use the exact same kernel as both system kernel and crash dump kernel. The current arm64 kernel is not relocatable in the exact sense but I see no problems in using the same binary when testing kdump. I tested the code with - ATF v1.1 + EDK2(UEFI) v3.0-rc0 - kernel v4.0 + Geoff' kexec v9 on - Base fast model, and - MediaTek MT8173-EVB using my own kexec-tools [1], currently v0.12. You may want to start a kernel with the following boot parameter: crashkernel=64M (or so, on model) and try $ kexec -p --load <vmlinux> --append ... $ echo c > /proc/sysrq-trigger To examine vmcore (/proc/vmcore), you should use - gdb v7.7 or later - crash + a small patch (to recognize v4.0 kernel) Changes from v1: * rebased to Geoff's v9 * tested this patchset on real hardware and fixed bugs: - added cache flush operation in ipi_cpu_stop() when shutting down the system. Otherwise, data saved in vmcore's note sections by crash_save_cpu() might not be flushed to dumped memory and crash command fail to fetch correct data. I will address Mark's commit[2] after Geoff takes care of it on kexec. - modified to use ioremap_cache() instead of ioremap() when reading crash memory. Otherwise, accessing /proc/vmcore on crash dump kernel might cause an alignment fault. * allows reserve_crashkernel() to handle "crashkernel=xyz[MG]" correctly, thanks to Pratyush Anand. And it now also enforces memory limit. * moved reserve_crashkernel() and reserve_elfcorehdr() to arm64_memblock_init() to clarify that they should be called before dma_contignuous_reserve().

Bug on LSK 3.18 Android branch when offlining a CPU

by Jon Medhurst (Tixy)

Hi With an ARM Landing Team branch based on LSK 3.18 Android I'm seeing a hang if I echo 0 > /sys/devices/system/cpu/cpu1/online After bisecting, I fixed this problem by reverting commit 553b785b5383 ("cpufreq: Iterate over all the possible cpus to create powerstats.") I was tempted to also revert the other scheduler and cpufreq mods from Google that are part of the same series, just as a precaution, because they don't fill me with confidence, but have left them in for now. -- Tixy

[PATCH] sched: fix nohz.next_balance update

by Vincent Guittot

Since commit d4573c3e1c99 ("sched: Improve load balancing in the presence of idle CPUs"), the ILB CPU starts with the idle load balancing of other idle CPUs and finishes with itself in order to speed up the spread of tasks in all idle CPUs. The this_rq->next_balance is still used in nohz_idle_balance as an intermediate step to gather the shortest next balance before updating nohz.next_balance. But the former has not been updated yet and is likely to be set with the current jiffies. As a result, the nohz.next_balance will be set with current jiffies instead of the real next balance date. This generates spurious kicks of nohz ilde balance. nohz_idle_balance must set the nohz.next_balance without taking into account this_rq->next_balance which is not updated yet. Then, this_rq will update nohz.next_update with its next_balance once updated and if necessary.

[PATCH v6 0/4] Add Mediatek MT8173 cpufreq driver

by Pi-Cheng Chen

MT8173 is a ARMv8 based SoC with 2 clusters. All CPUs in a single cluster share the same power and clock domain. This series tries to add cpufreq support for MT8173 SoC. changes in v6: - Move clock and regulator consumer properties document to the device tree bindings documents of MT8173 CPU DVFS clock driver - Add change log to describe what is implemented in the MT8173 cpufreq driver - Add missed rcu_read_unlock() in the error path - Move of_init_opp_table() call to make sure all required hardware resources are already there before it is called - Add comments to describe why both platform driver and deivce registration codes are put in the initcall function - Use the term "voltage tracking" instead of "voltage trace" according to an internal SoC document changes in v5: - Move resource allocation code from init() into probe() and remove some unused functions due to this change - Fix descriptions for device tree binding document - Address review comments for last version - Register CPU cooling device Changes in v4: - Add bindings for MT8173 cpufreq driver - Move OPP table back into device tree - Address comments for last version Changes in v3: - Implement MT8173 specific standalone cpufreq driver instead of using cpufreq-dt driver - Define OPP table in the driver source code until new OPP binding is ready Changes in v2: - Add intermediate frequency support in cpufreq-dt driver - Use voltage scaling code of cpufreq-dt for little cluster instead of implementaion in notifier of mtk-cpufreq driver - Code refinement for mtk-cpufreq driver Pi-Cheng Chen (4): dt-bindings: mediatek: Add MT8173 CPU DVFS clock bindings dt-bindings: mediatek: Add MT8173 cpufreq driver bindings cpufreq: mediatek: Add MT8173 cpufreq driver arm64: dts: mt8173: Add mt8173 cpufreq driver support .../devicetree/bindings/clock/mt8173-cpu-dvfs.txt | 83 ++++ .../devicetree/bindings/cpufreq/cpufreq-mt8173.txt | 134 ++++++ arch/arm64/boot/dts/mediatek/mt8173-evb.dts | 18 + arch/arm64/boot/dts/mediatek/mt8173.dtsi | 64 +++ drivers/cpufreq/Kconfig.arm | 7 + drivers/cpufreq/Makefile | 1 + drivers/cpufreq/mt8173-cpufreq.c | 524 +++++++++++++++++++++ 7 files changed, 831 insertions(+) create mode 100644 Documentation/devicetree/bindings/clock/mt8173-cpu-dvfs.txt create mode 100644 Documentation/devicetree/bindings/cpufreq/cpufreq-mt8173.txt create mode 100644 drivers/cpufreq/mt8173-cpufreq.c -- 1.9.1

[PATCH V3 00/16] OPP: Add code to support operating-points-v2 bindings

by Viresh Kumar

Hi Guys, Resending this again because: - opp-hz is now 64 bit long and so that required a binding update. - There is another 4 patch series that as updating turbo OPP support, along with updates to cpufreq core and cpufreq-dt driver. - A minor bug-fix in V2 4/11, which caused false positive for duplicate OPPs in some cases. Tested this on dual-core exynos board with the driver inbuilt as well as a module. Tried multiple insertion/removals of the module. Have tested cpufreq-dt driver with both old and new bindings. Also tried by sending some dummy OPPs that contained opp-hz greater than what can be captured by u32, to test the u64 updates. ----------x-----------------x------------- This adds code to support operating-points-v2 bindings. Not everything is supported yet, but most of the basic stuff is. Pushed here as well for reference: ssh://git@git.linaro.org/people/viresh.kumar/linux.git opp/v2 V2->V3: - Update to opp-hz binding to make it pass u64 value instead of 32 bit value. This is done to support clock rates greater than 4 GHz. - Merged two inter-related series, opp-v2 and turbo mode updates. - Fixed 4/11 from opp-v2 series, which cased false positive for duplicate OPPs in some cases. - Add a separate comment in _opp_add_dynamic() (5/16), to clearly specify that we pass &dev_opp->opp_list to list_for_each_entry_rcu() and not pass 'head' which contains the same value. Because head will get modified by the code and that may result in an infinite loop. - Accumulate more RBY tags. V1->V2: - 1/11 is a new patch which moves the bindings file into opp specific folder. - 'opp-suspend' binding got updated and is part of individual OPPs now, instead of a phandle present in the opp table. - Some more minor reformatting as suggested by Bartlomiej and Stephen, they were already posted as reply to earlier patches in V1.
