Native PCI drivers for root complex devices were originally all in drivers/pci/host/. Some of these devices can also be operated in endpoint mode. Drivers for endpoint mode didn't seem to fit in the "host" directory, so we put both the root complex and endpoint drivers in per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc. These per-device directories contain trivial Kconfig and Makefiles and clutter drivers/pci/. Make a new drivers/pci/controllers/ directory and collect all the device-specific drivers there. No functional change intended.

Expose a new system call allowing each thread to register one userspace memory area to be used as an ABI between kernel and user-space for two purposes: user-space restartable sequences and quick access to read the current CPU number value from user-space. * Restartable sequences (per-cpu atomics) Restartables sequences allow user-space to perform update operations on per-cpu data without requiring heavy-weight atomic operations. The restartable critical sections (percpu atomics) work has been started by Paul Turner and Andrew Hunter. It lets the kernel handle restart of critical sections. [1] [2] The re-implementation proposed here brings a few simplifications to the ABI which facilitates porting to other architectures and speeds up the user-space fast path. Here are benchmarks of various rseq use-cases. Test hardware: arm32: ARMv7 Processor rev 4 (v7l) "Cubietruck", 2-core x86-64: Intel E5-2630 v3@2.40GHz, 16-core, hyperthreading The following benchmarks were all performed on a single thread. * Per-CPU statistic counter increment getcpu+atomic (ns/op) rseq (ns/op) speedup arm32: 344.0 31.4 11.0 x86-64: 15.3 2.0 7.7 * LTTng-UST: write event 32-bit header, 32-bit payload into tracer per-cpu buffer getcpu+atomic (ns/op) rseq (ns/op) speedup arm32: 2502.0 2250.0 1.1 x86-64: 117.4 98.0 1.2 * liburcu percpu: lock-unlock pair, dereference, read/compare word getcpu+atomic (ns/op) rseq (ns/op) speedup arm32: 751.0 128.5 5.8 x86-64: 53.4 28.6 1.9 * jemalloc memory allocator adapted to use rseq Using rseq with per-cpu memory pools in jemalloc at Facebook (based on rseq 2016 implementation): The production workload response-time has 1-2% gain avg. latency, and the P99 overall latency drops by 2-3%. * Reading the current CPU number Speeding up reading the current CPU number on which the caller thread is running is done by keeping the current CPU number up do date within the cpu_id field of the memory area registered by the thread. This is done by making scheduler preemption set the TIF_NOTIFY_RESUME flag on the current thread. Upon return to user-space, a notify-resume handler updates the current CPU value within the registered user-space memory area. User-space can then read the current CPU number directly from memory. Keeping the current cpu id in a memory area shared between kernel and user-space is an improvement over current mechanisms available to read the current CPU number, which has the following benefits over alternative approaches: - 35x speedup on ARM vs system call through glibc - 20x speedup on x86 compared to calling glibc, which calls vdso executing a "lsl" instruction, - 14x speedup on x86 compared to inlined "lsl" instruction, - Unlike vdso approaches, this cpu_id value can be read from an inline assembly, which makes it a useful building block for restartable sequences. - The approach of reading the cpu id through memory mapping shared between kernel and user-space is portable (e.g. ARM), which is not the case for the lsl-based x86 vdso. On x86, yet another possible approach would be to use the gs segment selector to point to user-space per-cpu data. This approach performs similarly to the cpu id cache, but it has two disadvantages: it is not portable, and it is incompatible with existing applications already using the gs segment selector for other purposes. Benchmarking various approaches for reading the current CPU number: ARMv7 Processor rev 4 (v7l) Machine model: Cubietruck - Baseline (empty loop): 8.4 ns - Read CPU from rseq cpu_id: 16.7 ns - Read CPU from rseq cpu_id (lazy register): 19.8 ns - glibc 2.19-0ubuntu6.6 getcpu: 301.8 ns - getcpu system call: 234.9 ns x86-64 Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz: - Baseline (empty loop): 0.8 ns - Read CPU from rseq cpu_id: 0.8 ns - Read CPU from rseq cpu_id (lazy register): 0.8 ns - Read using gs segment selector: 0.8 ns - "lsl" inline assembly: 13.0 ns - glibc 2.19-0ubuntu6 getcpu: 16.6 ns - getcpu system call: 53.9 ns - Speed (benchmark taken on v8 of patchset) Running 10 runs of hackbench -l 100000 seems to indicate, contrary to expectations, that enabling CONFIG_RSEQ slightly accelerates the scheduler: Configuration: 2 sockets * 8-core Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz (directly on hardware, hyperthreading disabled in BIOS, energy saving disabled in BIOS, turboboost disabled in BIOS, cpuidle.off=1 kernel parameter), with a Linux v4.6 defconfig+localyesconfig, restartable sequences series applied. * CONFIG_RSEQ=n avg.: 41.37 s std.dev.: 0.36 s * CONFIG_RSEQ=y avg.: 40.46 s std.dev.: 0.33 s - Size On x86-64, between CONFIG_RSEQ=n/y, the text size increase of vmlinux is 567 bytes, and the data size increase of vmlinux is 5696 bytes.

由 Greg Kroah-Hartman 提交于
The Lustre filesystem has been in the kernel tree for over 5 years now. While it has been an endless source of enjoyment for new kernel developers learning how to do basic codingstyle cleanups, as well as an semi-entertaining source of bewilderment from the vfs developers any time they have looked into the codebase to try to figure out how to port their latest api changes to this filesystem, it has not really moved forward into the "this is in shape to get out of staging" despite many half-completed attempts. And getting code out of staging is the main goal of that portion of the kernel tree. Code should not stagnate and it feels like having this code in staging is only causing the development cycle of the filesystem to take longer than it should. There is a whole separate out-of-tree copy of this codebase where the developers work on it, and then random changes are thrown over the wall at staging at some later point in time. This dual-tree development model has never worked, and the state of this codebase is proof of that. So, let's just delete the whole mess. Now the lustre developers can go off and work in their out-of-tree codebase and not have to worry about providing valid changelog entries and breaking their patches up into logical pieces. They can take the time they have spend doing those types of housekeeping chores and get the codebase into a much better shape, and it can be submitted for inclusion into the real part of the kernel tree when ready.

There aren't actually any files in the tree that match these patterns right now, but we've just started submitting our drivers so I thought it would be good to make sure there's at least someone at SiFive who's listed as maintaining them. I'm leaving the RISC-V lists on here because: * As of today, all the RISC-V ASICs that people can actually buy are from SiFive -- though hopefully there'll be more soon! * The RTL for many of our devices is open source, so I anticipate these devices might make they way chips from other vendors. * We may standardize some of these devices as part of a RISC-V specification at some point in the future. I'm a bit swamped right now so I might not be the most active maintainer of these drivers, but I think it'd be good to make sure someone who has hardware access gets CC'd on updates to our drivers just as a sanity check. Hopefully that's an OK way to handle this. Signed-off-by: NPalmer Dabbelt <palmer@sifive.com>

Qualcomm Process Voltage Scaling Tables defines the voltage and frequency value based on the msm-id in SMEM and speedbin blown in the efuse combination. The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC to provide the OPP framework with required information. This is used to determine the voltage and frequency value for each OPP of operating-points-v2 table when it is parsed by the OPP framework.

The net_failover driver provides an automated failover mechanism via APIs to create and destroy a failover master netdev and manages a primary and standby slave netdevs that get registered via the generic failover infrastructure. The failover netdev acts a master device and controls 2 slave devices. The original paravirtual interface gets registered as 'standby' slave netdev and a passthru/vf device with the same MAC gets registered as 'primary' slave netdev. Both 'standby' and 'failover' netdevs are associated with the same 'pci' device. The user accesses the network interface via 'failover' netdev. The 'failover' netdev chooses 'primary' netdev as default for transmits when it is available with link up and running. This can be used by paravirtual drivers to enable an alternate low latency datapath. It also enables hypervisor controlled live migration of a VM with direct attached VF by failing over to the paravirtual datapath when the VF is unplugged.

The failover module provides a generic interface for paravirtual drivers to register a netdev and a set of ops with a failover instance. The ops are used as event handlers that get called to handle netdev register/ unregister/link change/name change events on slave pci ethernet devices with the same mac address as the failover netdev. This enables paravirtual drivers to use a VF as an accelerated low latency datapath. It also allows migration of VMs with direct attached VFs by failing over to the paravirtual datapath when the VF is unplugged.

Add a document for the macro language introduced to Kconfig. The motivation of this work is to move the compiler option tests to Kconfig from Makefile. A number of kernel features require the compiler support. Enabling such features blindly in Kconfig ends up with a lot of nasty build-time testing in Makefiles. If a chosen feature turns out unsupported by the compiler, what the build system can do is either to disable it (silently!) or to forcibly break the build, despite Kconfig has let the user to enable it. By moving the compiler capability tests to Kconfig, features unsupported by the compiler will be hidden automatically. This change was strongly prompted by Linus Torvalds. You can find his suggestions [1] [2] in ML. The original idea was to add a new attribute with 'option shell=...', but I found more generalized text expansion would make Kconfig more powerful and lovely. The basic ideas are from Make, but there are some differences.
