Linux 4.17 has been released on 3 June 2018.

Summary: This release adds support for AMD Radeon Vega 12 and it enables the "display code" by default in supported AMD Radeon GPUs; it also adds a kernel TLS receive path; a more efficient idle loop that prevent CPUs from spending too much time in shallow idle states; eight unmaintained architectures have been removed and another, the Andes NDS32 architecture, has been added; XFS has gained lazytime support; the CPU load estimations have been modified; Intel Cannonlake GPUs are supported and a kernel memory consistency model has been added; and many new drivers and other improvements.

1. Prominent features

1.1. AMD Radeon Vega 12 support + "Display Code" enabled by default

This release adds support for AMD Radeon Vega 12.

It also enables by default the display code added in Linux 4.15

Code: commit, commit

1.2. Kernel TLS receive path

Linux 4.13 added a feature to speed up TLS traffic by creating an in-kernel TLS pseudo implementation that did let the kernel send TLS messages. This release includes support for the receiving side.

Code: commit, commit

1.3. A more efficient idle loop

This release reworks the idle loop in order to prevent CPUs from spending too much time in shallow idle states. It reduces idle power on some systems by 10% or more and may improve performance of workloads in which the idle loop overhead matters.

1.4. Removal of unused architectures

Eight architectures have been removed due to lack of maintenance: score, blackfin, CRIS, frv, m32r, metag, mn10300 and tile

1.5. New NDS32 architecture

While eight unmaintained architectures are being removed, one has been added: NDS32. The Andes nds32 architecture supports Linux for Andes's N10, D10, N13, N15, D15 processor cores. It is based on the patented 16/32-bit AndeStar RISC-like architecture. AndesCores range from highly performance-efficient small-footprint cores for microcontrollers and deeply-embedded applications to 1GHz+ cores running Linux, covering general-purpose N-series cores for a wide range of computing need, DSP-capable D-series cores for digital signal control, instruction-extensible E-series cores for application-specific acceleration, and secure S-series cores for best protection of the most valuable. Customers together have shipped over 2.5 billion SoC’s with Andes processors embedded (including non-MMU IP cores).

Code: (including interrupt controller driver and timer driver). It is able to boot to shell and passes most LTP-2017 testsuites in nds32 AE3XX platform https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/nds32?id=e71ea3badae55a69a44b8fcb46ae7b547529b3761arch/nds32

1.6. XFS lazytime support

XFS adds support for the lazytime, a feature that helps to improve the performance impact caused by atime updates.

Code: commit

1.7. Better load estimation

This release changes the algorithms used to estimate the CPU load to make it a better fit for the scheduling of tasks common in embedded mobile use-cases, without affecting other classes of workloads.

1.8. Intel Cannonlake support

Support for Intel Cannonlake GPUs is enabled in this release.

Code: commit, commit, commit

1.9. Latest protections against CPU bugs

This release adds support for SSBD mitigation

Code: commit, commit, commit, commit, commit, commit

1.10. Provide a Linux-kernel memory model

This release adds the Linux Kernel Memory Consistency Model (LKMM) subsystem, which is an an array of tools in tools/memory-model/ that formally describe the Linux memory coherency model (a.k.a. Documentation/memory-barriers.txt), and also produce 'litmus tests' in form of kernel code which can be directly executed and tested.

Code: commit

2. Core (various)

firmware
- Enable run time change of forcing fallback loader commit
- Enable to force disable the fallback mechanism at run time commit
Add KASAN checks to atomic operations commit, commit, commit, commit
Add trace events around the initcall functions, which adds the necessary information to analyze the initcalls without the high overhead of printk()s that can substantially slow down the boot process commit, commit, commit, commit
(FEATURED) Power management: rework the idle loop commit, commit, commit, commit , commit, ,commit, commit, commit, commit, commit
Task scheduler
- (FEATURED) Better load estimation commit, commit, commit, commit
- boot parameters "nohz_full=" or "isolcpus=nohz" will now offload the residual 1Hz tick to the global workqueue so that the nohz_full CPUs don't have anymore tick (assuming nothing else requires it) as their residual 1Hz tick is offloaded to the housekeepers commit, commit, commit, commit, commit, commit, commit, commit
- Reduce migrations and conflicts with automatic NUMA balancing commit, commit, commit, commit, commit, commit
prctl
- Add force disable speculation commit

Pin stack limit during exec commit
Hibernation: Add a new /sys/power/resume_offset that lets userspace specify the offset and disk to use when initiating a hibernate cycle commit
RCU: Remove obsolete statistics from debugfs commit, commit, commit, commit

XFS
- Implement the lazytime mount option commit
AFS
- Implement @cell substitution handling commit
- Implement @sys substitution handling commit
- Introduce a statistics proc file commit
- Add stats for data transfer operations commit
F2FS
- Introduce new mount option fsync_mode to control the policy of fsync. fsync_mode=posix is set by default, and means that f2fs uses a light fsync, which follows POSIX semantics. fsync_mode=strict means that it's a heavy fsync, which behaves in line with xfs, ext4 and btrfs, where generic/342 will pass, but the performance will regress commit
- Add three block allocation policies to pass down write hints given by user commit, commit, commit

6. Tracing and perf

Modernize the kprobe and uprobe creation/destruction tooling ABIs. The existing text based APIs (kprobe_events and uprobe_events in tracefs), are naive, limited ABIs that are not really suited for modern, robust tooling. This release introduces a file descriptor based ABI that does not have these limitations: it introduces the 'perf_kprobe' and 'perf_uprobe' PMUs and extend the perf_event_open() syscall to create events with a kprobe/uprobe attached to them commit, commit, commit

perf trace/stat: Implement support for the -G/--cgroup target in 'perf trace'. One can set a cgroup as a default cgroup to be used by all events or set cgroups with the 'perf stat' and 'perf record' behaviour, i.e. '-G A' will be the cgroup for events defined so far in the command line commit
perf stat
- Add the --interval-count option to print count deltas for fixed number of times commit
- Add the --timeout option option to print counts after a period of time commit

uprobe: Add support for attaching uprobes to binaries in overlayfs commit

7. Virtualization

User-mode linux
- Epoll based IRQ controller commit
- High Performance UML Vector Network Driver commit
KVM: Allow to query for hints about the configuration of the guests. The first hint KVM_HINTS_DEDICATED, is set if the guest has dedicated physical CPUs for each vCPU (i.e. pinning and no over-commitment). This allows optimizing spinlocks and tells the guest to avoid PV TLB flush commit
uio: uio_hv_generic: support sub-channels commit
