Put back in the simplification of the aiodone daemon. Previous "breakage" of the swap on arm64 has been found to be an issue on one machine the rockpro/arm64 related to a deadlock built into the sdmmc(4) stack interacting with swapping code both running under KERNEL_LOCK(). This issue is easily reproducible on -current and entering swap when building LLVM on a rockpro crashes the machine by memory corruption. Tested by mlarkin@ on octeon & i386, by myself on amd64 & arm64 and by sthen@ on i386 port bulk. ok beck@ some time ago. Previous commit message: Simplify the aiodone daemon which is only used for async writes. - Remove unused support for asynchronous read, including error conditions - Grab the proper lock for each page that has been written to swap. This allows to enable an assertion in uvm_page_unbusy(). - Move the uvm_anon_release() call outside of uvm_page_unbusy() and assert for the different anon cases. ok beck@, kettenis@ |

Finally remove the kernel lock from IPv6 neighbor discovery. ND6 entries in rt_llinfo are protected either by exclusive netlock or the ND6 mutex. The performance critical lookup path in nd6_resolve() uses shared netlock, but is not lockless. In contrast to ARP it grabs the mutex also in the common case. tested by Hrvoje Popovski; with and OK kn@ |

vmm(4)/vmd(8): switch to anonymous shared mappings. While splitting out emulated virtio network and block devices into separate processes, I originally used named mappings via shm_mkstemp(3). While this functionally achieved the desired result, it had two unintended consequences: 1) tearing down a vm process and its child processes required excessive locking as the guest memory was tied into the VFS layer. 2) it was observed by mlarkin@ that actions in other parts of the VFS layer could cause some of the guest memory to flush to storage, possibly filling /tmp. This commit adds a new vmm(4) ioctl dedicated to allowing a process request the kernel share a mapping of guest memory into its own vm space. This requires an open fd to /dev/vmm (requiring root) and both the "vmm" and "proc" pledge(2) promises. In addition, the caller must know enough about the original memory ranges to reconstruct them to make the vm's ranges. Tested with help from Mischa Peters. ok mlarkin@ |

give softnet threads unique names by suffixing softnet with their index. ie, you'll see softnet0, softnet1, etc in top/ps/etc now instead of just softnet on these threads. this is done by wrapping the taskq and name up in a softnet struct. ok patrick@ bluhm@ mvs@ kn@ sashan@ |

Implement the TCP/IP layer for hardware TCP segmentation offload. If the driver of a network interface claims to support TSO, do not chop the packet in software, but pass it down to the interface layer. Precalculate parts of the pseudo header checksum, but without the packet length. The length of all generated smaller packets is not known yet. Driver and hardware will use the mbuf packet header field ph_mss to calculate it and update checksum. Introduce separate flags IFCAP_TSOv4 and IFCAP_TSOv6 as hardware might support ony one protocol family. The old flag IFXF_TSO is only relevant for large receive offload. It is missnamed, but keep that for now. Note that drivers do not set TSO capabilites yet. Also the ifconfig flags and pseudo interfaces capabilities will be done separately. So this commit should not change behavior. heavily based on the work from jan@; OK sashan@ |

Use separate IFCAPs for LRO and TSO. This diff introduces separate capabilities for TCP offloading. We split this into LRO (large receive offloading) and TSO (TCP segmentation offloading). LRO can be turned on/off via tcprecvoffload option of ifconfig and is not inherited to sub interfaces. TSO is inherited by sub interfaces to signal this hardware offloading capability to the network stack. With tweaks from bluhm, claudio and dlg ok bluhm, claudio |

Introduce temporary PR_MPSYSCTL flag to mark (*pr_sysctl)() handler MP safe. We have may of them, so use flag instead of pushing kernel lock within. Unlock ip_sysctl(). Still take kernel lock within IPCTL_MRTSTATS case. It looks like `mrtstat' protection is inconsistent, so keep locking as it was. Since `mrtstat' are counters, it make sense to rework them into per CPU counters with separate diffs. Feedback and ok from bluhm@ |

Tolerate difference in some of the features advertised by the ID_AA64PFR0_EL1 register across cores. The CSV2/CSV3 features are handled on a per-core basis so it is fine if they are different. And we only support 64-bit userland so it is fine if the EL0/EL1/EL2/EL3 fields are different too. This prevents us from printing a warning on the Rockchip RK3588 SoC which combines Cortex-A55 with Cortex-A76 that implement a sightly different feature set. ok deraadt@, mlarkin@ |

Implement battery management sysctl. This will provide a set of sysctls to control the charging of laptop batteries: * hw.battery.chargemode (int) -1: force discharge 0: inhibit charge 1: auto In auto mode charging may be controlled by: * hw.battery.chargestop (int) Percentage (0-100) of last full capacity at which the battery should stop charging. * hw.battery.chargestart (int) Percentage (0-100) of last full capacity at which the battery should start charging. The idea is that with hw.battery.chargemode=1 hw.battery.chargestop=80 hw.battery.chargestart=75 the battery would be kept charged within the range between 75% and 80%. Allowable settings and some details of the behavior may differ between hardware implementations. Committing this early to easy testing of further diffs that implement this functionality in acpithinkpad(4) and aplsmc(4). ok kn@ |
