2020-01-21Import dt(4) a driver and framework for Dynamic Profiling.Martin Pieuchot
The design is fairly simple: events, in the form of descriptors on a ring, are being produced in any kernel context and being consumed by a userland process reading /dev/dt. Code and hooks are all guarded under '#if NDT > 0' so this commit shouldn't introduce any change as long as dt(4) is disable in GENERIC. ok kettenis@, visa@, jasper@, deraadt@

noone seems to use it, and we should not encourage people to use it by having it available. it's been disabled for most of the last release and noones asked for it in 6.6, so i'm taking that as an ok for this removal.

2019-09-29Replace dwge(4) with a new driver based on dwxe(4). There are manyMark Kettenis
similarities between the two and using a common approach helps fixing bugs. The new driver is better integrated with the device tree framework and is faster (mainly because the DMA engine is configured properly now). Tested on all currently supported variants of the hardware. ok jsg@, jmatthew@
2019-09-07Remove tz, the kernel timezone.cheloha
After removing timezone support from date(1), msdosfs, gettimeofday(2), settimeofday(2), boot_config(8), config(8), and introducing kern.utc_offset sysctl(2) to replace the DST/TIMEZONE options(4) to support running the RTC at an offset from UTC, the kernel timezone is unused and we can delete it. With this commit the kernel timezone now appears to be extinct in upstream BSD, though it does survive in XNU: https://github.com/opensource-apple/xnu/blob/0a798f6738bc1db01281fc08ae024145e84df927/bsd/conf/param.c#L83 Prompted by tedu@ some time back, and inspired by NetBSD and FreeBSD's work in this area. ok deraadt@
2019-08-21sysctl(2): add kern.utc_offset: successor to the DST/TIMEZONE options(4)cheloha
The DST and TIMEZONE options(4) are incompatible with KARL, so we need some other way to compensate for an RTC running with a known offset. Enter kern.utc_offset, an offset in minutes East of UTC. TIMEZONE has always been minutes West, but this is inconsistent with how everyone else talks about timezones, hence the flip. TIMEZONE has the advantage of being compiled into the binary. Our new sysctl(2) has no such luck, so it needs to be set as early as possible in boot, from sysctl.conf(5), so we can correct the kernel clock from the RTC's local time to UTC before daemons like ntpd(8) and cron(8) start. To encourage this, kern.utc_offset is made immutable after the securelevel(7) is raised to 1. Prompted by yasuoka@. Discussed with deraadt@, kettenis@, yasuoka@. Additional testing by yasuoka@. ok deraadt@, yasuoka@

2019-08-02per-process itimers: itimerval -> itimerspeccheloha
Loongson runs at 128hz. 128 doesn't divide evenly into a million, but it does divide evenly into a billion. So if we do the per-process itimer bookkeeping with itimerspec structs we can have error-free virtual itimers on loongson just as we do on most other platforms. This change doesn't fix the virtual itimer error alpha, as 1024 does not divide evenly into a billion. But this doesn't make the situation any worse, either. ok deraadt@

2019-05-04Improve the interaction between efifb(4), inteldrm(4) and radeondrm(4)Mark Kettenis
when we have a serial console by introducing the notion of a "primary" graphics device. The primary graphics device is the one set up and used by firmware (BIOS, UEFI). The goal is to make sure that wsdisplay0 and drm0 reliably attach to the primary graphics device such that X works out of the box even if you have multiple cards or if you are using a serial console. This also fixes the situation where inteldrm(4) or radeondrm(4) would take over the console on UEFI systems even if the kernel was booted with a serial console. ok jsg@

2019-02-26Introduce safe memory reclamation, a mechanism for reclaiming sharedVisa Hankala
objects that readers can access without locking. This provides a basis for read-copy-update operations. Readers access SMR-protected shared objects inside SMR read-side critical section where sleeping is not allowed. To reclaim an SMR-protected object, the writer has to ensure mutual exclusion of other writers, remove the object's shared reference and wait until read-side references cannot exist any longer. As an alternative to waiting, the writer can schedule a callback that gets invoked when reclamation is safe. The mechanism relies on CPU quiescent states to determine when an SMR-protected object is ready for reclamation. The <sys/smr.h> header additionally provides an implementation of singly- and doubly-linked lists that can be used together with SMR. These lists allow lockless read access with a concurrent writer.

2018-12-20add bpe(4) or Backbone Provider Edge interfacesDavid Gwynne
Backbone refers to 802.1ah or 802.1Q Provider Backbone Bridges (PBB), or mac-in-mac, which is like vlans except it completely encapsulates the inner packet rather than just add a shim to it. This removes the need for Backbone Core Bridges (ie, switches between bpe instances) to know all the addresses on all the networks.

2018-08-21Rework kcov kernel config. Instead of treating kcov as both an option and aanton
pseudo-device, get rid of the option. Enabling kcov now requires the following line to be added to the kernel config: pseudo-device kcov 1 This is how pseudo devices are enabled in general.
