2019-01-11Move the placement of pmap_kernel's toplevel PML4 pageMike Larkin
This change moves the PML4 for pmap_kernel elsewhere during early boot. Lower levels of pmap_kernel will be moved in subsequent changes, but there are other pmap changes coming that need to be integrated first. In snaps for 3 days, no fallout seen. ok deraadt and substantial input and help from guenther@ cvs: ----------------------------------------------------------------------

2019-01-09Enable Spleen in wsfont and modify the font selection logic at runtimeFrederic Cambus
in rasops(9) to allow selecting larger fonts when available. Summary of the changes: - Enable spleen8x16 for all architectures, replacing bold8x16_iso1. - Enable spleen12x24 on all arches but sparc64, replacing gallant12x22. - Enable spleen16x32 and spleen32x64 on amd64, i386, and arm64 for GENERIC kernels. - Modify the font selection logic in rasops(9) so the 16x32 and 32x64 fonts are selected if at least 120 columns can be displayed. Screens with widths equal or larger than 1920px will use the 16x32 font, and screens with widths equal or larger than 3840px the 32x64 one. OK kettenis@, ratchov@, deraadt@
2019-01-09implement an if_enqueue handler for vlan(4)David Gwynne
this allows vlan packets to bypass the ifq handling, which allows packets to be encapsulated concurrently by any context. the code falls back to ifqs if hfsc is enabled on the vlan interface, otherwise it encaps the packet immedate and enqueues it on the parent interface. hrove popovski has seen a performance bump in certain configurations from this change. ok mpi@ no objections claudio@
2019-01-09split if_enqueue up so drivers can replace ifq handling if neededDavid Gwynne
if_enqueue() still makes sure packets get handled by pf on the way out, and seen by bridge if needed. however instead of falling through to ifq mapping and output, it now calls a function pointer in the ifnet struct. that pointer defaults to the ifq handling, but drivers can override it to bypass ifq processing. the most obvious users of the function pointer will be virtual interfaces, eg, vlan(4). ifqs are good if you need to serialise access to the thing that transmits packets (like hardware rings on nics), or mitigate the number of times you do ring processing, but neither of those things are desirable on vlan interfaces. ideally vlan could transmit on any cpu without having packets serialised by it's own ifq before being pushed down to an arbitrary number of rings on the parent interface. bypassing ifqs means the driver can push the vlan tag on concurrently and push down to the parent frmo any cpu. ok mpi@ no objection from claudio@

They are only used if VIRTIO_DEBUG is enabled. This should make the kernel slightly smaller.

2019-01-07tweak ohci_checkrev so it doesnt print a leading comma and space.David Gwynne
it assumes that it always followed an interrupt string, but we don't print that on fdt. having the bus responsible for the whitespace means the fdt glue can print a colon to separate the bus info from checkrev output, while every other glue keeps the comma. ok deraadt@

2019-01-06Fix unsafe use of ptsignal() in mi_switch().Visa Hankala
ptsignal() has to be called with the kernel lock held. As ensuring the locking in mi_switch() is not easy, and deferring the signaling using the task API is not possible because of lock order issues in mi_switch(), move the CPU time checking into a periodic timer where the kernel can be locked without issues. With this change, each process has a dedicated resource check timer. The timer gets activated only when a CPU time limit is set. Because the checking is not done as frequently as before, some precision is lost. Use of timers adapted from FreeBSD. OK tedu@ Reported-by: syzbot+2f5d62256e3280634623@syzkaller.appspotmail.com
