1. Prominent features

1.1. New driver amdgpu for modern AMD Radeon hardware

This release includes the amdgpu driver, a new driver for VI+ AMD asics. It currently supports Tonga, Iceland, and Carrizo and also contains an option to build support for CI parts for testing. All major functionality is supported (displays, gfx, compute, dma, video decode/encode, etc.). Power management is working on Carrizo, but is still being worked on for Tonga and Iceland.

The purpose of this driver is to unify AMD's Linux offerings: the functionality that it's kept as private code in the Catalyst driver will be either ported to this driver or will run as a user-space private blob that uses the new driver.

1.2. Add virtio gpu driver

[http://wiki.libvirt.org/page/Virtio Virtio] drivers are "fake" drivers that are used to make communication between virtualization guests and host faster, because emulating real hardware is complicated and ineficcient.

This release adds a virtual GPU driver for virtio. It can be used with QEMU based VMMs (like KVM or Xen). For now it supports kernel-modesetting: The xorg modesetting driver can handle the device just fine, the framebuffer for fbcon is there too. Qemu patches for the host side are under review currently. This initial revision has only 2d support, 3d (virgl) support requires some more work on the qemu side and will be added later.

1.3. Atomic modesetting API enabled by default

This release finally completes the atomic modesetting API and enables it by default. For details about the atomic modesetting API and why it is neccesary, read these recommended LWN articles: [https://lwn.net/Articles/653071/ Atomic mode setting design overview, part 1], and [https://lwn.net/Articles/653466/ part 2]

1.4. Stacking of security modules

There are several security modules in the Linux kernel, but only one can be used. For a very long time, developers have wanted to be able to be able to use more than one at the same time ("stacking"). This release adds support for stacking of linux security modules

1.5. Queued spinlocks become the default spinlock implementation

This release adds support in the x86 architecture for queue-based spinlocks that can replace the default ticket spinlock without increasing the size of the spinlock data structure.

The queue spinlock has slightly better performance than the ticket spinlock in uncontended case, and its performance can be much better with moderate to heavy contention. It is especially suitable for NUMA machines with at least 2 sockets. Though even at the 2-socket level, there can be significant speedup depending on the workload. It can also improve the performance of an I/O and interrupt intensive stress test with a lot of spinlock contention on a 2-socket system by up to 20%.

1.6. cgroup writeback support

The Linux kernel can throttle processes than are trying to write too many pages to the disk ("writeback"). But this control was only global. This release adds support for writeback control of processes inside a cgroup.

1.7. Reintroduction of the H8/300 architecture

Linux added support for the [http://sg.renesas.com/products/mpumcu/h8/h8300/index.jsp H8/300 architecture] in Linux [https://lwn.net/Articles/29489/ 2.5.68]. But it got removed [http://kernelnewbies.org/Linux_3.13-DriversArch#head-822cd1ebdfb3ba567aae68fc49dd9ee2244eeb2f in Linux 3.13] due to lack of maintainance.

In this release, the H8/300 architecture has got support again, and it's being reincorporated to the tree

* Allow the watchdog to run by default only on the housekeeping cores when nohz_full is in effect; this seems to be a good compromise short of turning it off completely (since the nohz_full cores can't tolerate a watchdog). To provide customizability, a /proc/sys/kernel/watchdog_cpumask file is added so that the set of cores running the watchdog can be tuned to different values after bootup [https://git.kernel.org/torvalds/c/b5242e98c1cb834feb1e84026f09a4796b49eb4d commit], [https://git.kernel.org/torvalds/c/f51c0eaee39e306458d2bf8a30e010615fa451cc commit], [https://git.kernel.org/torvalds/c/fe4ba3c34352b7e8068b7f18eb233444aed17011 commit]

6. Block layer

• The libnvdimm sub-system introduces, in addition to the libnvdimm-core, 4 drivers / enabling modules (common code to all: [https://git.kernel.org/torvalds/c/88793e5c774ec69351ef6b5200bb59f532e41bca (merge)])

  • NFIT: Add ACPI NVDIMM Firmware Interface Table (NFIT) support: It adds infrastructure to probe ACPI 6 compliant platforms for NVDIMMs (NFIT) and register a libnvdimm device tree. In addition to storage devices this also enables libnvdimm to pass ACPI._DSM messages for platform/dimm configuration.
  • PMEM: Initially merged in v4.1 this driver for contiguous spans of persistent memory address ranges is re-worked to drive PMEM-namespaces emitted by the libnvdimm-core. In this update the PMEM driver, on x86, gains the ability to assert that writes to persistent memory have been flushed all the way through the caches and buffers in the platform to persistent media.
  • BLK: This new driver enables access to persistent memory media through "Block Data Windows" as defined by the NFIT. The primary difference of this driver to PMEM is that only a small window of persistent memory is mapped into system address space at any given point in time. Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access different portions of the media. BLK-mode, by definition, does not support DAX
  • BTT: This is a library, optionally consumed by either PMEM or BLK, that converts a byte-accessible namespace into a disk with atomic sector update semantics (prevents sector tearing on crash or power loss)

• Make CFQ default to IOPS mode on SSDs [https://git.kernel.org/torvalds/c/41c0126b3f22ef36b97b3c38b8f29569848a5ce2 commit]

• xen: block: add multi-page ring support, so that more requests can be issued by using more than one pages as the request ring between blkfrontand backend. As a result, the performance can get improved significantly. If using 64 pages as the ring, the IOPS increased about 15 times for the throughput testing and above doubled for the latency testing [https://git.kernel.org/torvalds/c/86839c56dee28c315a4c19b7bfee450ccd84cd25 commit]

11. Networking

• TCP: Add CAIA Delay-Gradient (CDG) congestion control. CDG modifies the TCP sender in order to: -Use the delay gradient as a congestion signal; -Back off with an average probability that is independent of the RTT; - Coexist with flows that use loss-based congestion control, i.e., flows that are unresponsive to the delay signal; Tolerate packet loss unrelated to congestion.(disabled by default. Its FreeBSD implementation [http://www.ietf.org/proceedings/84/iccrg.html was presented for the ICCRG] in July 2012 [https://git.kernel.org/torvalds/c/2b0a8c9eee81882fc0001ccf6d9af62cdc682f9e commit]

• Add IP_BIND_ADDRESS_NO_PORT to overcome bind(0) limitations: When an application needs to force a source IP on an active TCP socket it has to use bind(IP, port=x). As most applications do not want to deal with already used ports, x is often set to 0, meaning the kernel is in charge to find an available port. But kernel does not know yet if this socket is going to be a listener or be connected. This patch adds a new SOL_IP socket option, asking kernel to ignore the 0 port provided by application in bind(IP, port=0) and only remember the given IP address. The port will be automatically chosen at connect() time, in a way that allows sharing a source port as long as the 4-tuples are unique [https://git.kernel.org/torvalds/c/90c337da1524863838658078ec34241f45d8394d commit]

• TCP: Add rfc3168, section 6.1.1.1. fallback for outgoing ECN connections. In other words, this work adds a retry with a non-ECN setup SYN packet, as suggested from the RFC on the first timeout. For users explicitly not wanting this which can be in DC use case, a net.ipv4.tcp_ecn_fallback knob is added that allows for disabling the fallback [https://git.kernel.org/torvalds/c/492135557dc090a1abb2cfbe1a412757e3ed68ab commit]

• switchdev: Add VLAN dump support to switchdev port's bridge_getlink. iproute2 "bridge vlan show" cmd already knows how to show the vlans installed on the bridge and the device , but (until now) no one implemented the port vlan part of the netlink message [https://git.kernel.org/torvalds/c/06baa3d0fb8491b21d579d3220569730c01efacc (merge)]

• Add a netdev driver for GENEVE (GEneric NEtwork Virtualization Encapsulation) tunnels. It allows one to create geneve virtual interfaces that provide Layer 2 Networks over Layer 3 Networks. GENEVE is often used to tunnel virtual network infrastructure in virtualized environments.

• Export the value of the linkdown sysctl to netconf [https://git.kernel.org/torvalds/c/974d7af5fcc295dcf8315255142b2fe44fd74b0c commit]

• IPv6: IPv6 flow labels have been an unmitigated disappointment thus far. Support in HW devices to use them for ECMP is lacking, and OSes don't turn them on by default. This release splits the flow label space into two ranges: 0-7ffff is reserved for flow label manager, 80000-fffff will be used for creating auto flow labels (per RFC6438). This should give Linux a path to enabling auto flow labels by default for all IPv6 packets. It can be disabled with sysctl flowlabel_state_ranges [https://git.kernel.org/torvalds/c/82a584b7cd366511a22e37675b029cf2fb58e291 commit]
