- If the config had both an le@pci and a pcn, simply remove le@pci
(pcn would match at a higher priority anyway).
- If the config had le@pci enabled, but no pcn, change le@pci to pcn.
- If the config had le@pci commented out, but no pcn, change le@pci
to pcn and leave it commented out.
The pcn driver supports more chips than le@pci and does DMA directly
to/from mbufs rather than memory copies.
a thread can exit with waiters still hanging off it (cancellation when
waiting on a condvar) so deal with all/any crappy failure like that and
make sure there are never any waiters left before exiting. Maybe of help

PR: bin/50350: rump/rumpkern/t_sp/stress_{long,short} fail on Core 2
is to get the thread to go through the slow path. If there are waiters,
process them there and then. Should not affect well behaved apps. Maybe

- in the !__HAVE_MM_MD_DIRECT_MAPPED_PHYS case pass UVM_KMF_WIRED so that
the mappings are removed and the KVA is released. Fixes the KASSERT
seen in the automated test runs.
- in the __HAVE_MM_MD_DIRECT_MAPPED_PHYS case we can work out pa much
easier than caling pmap_extract.
life without its self->pt_lid being filled in.
- Fix an error path in _lwp_create(). If the new LID can't be copied out,
then get rid of the new LWP (i.e. either succeed or fail, not both).
- Mark l_dopreempt and l_nopreempt volatile in struct lwp.
Several of us have been setting this in /etc/sysctl.conf for months, to
get better performance from applications that require synced audio, etc.
It's also mentioned as a good value with low overhead on most archs here:
https://mail-index.netbsd.org/tech-kern/2019/12/07/msg025830.html
We could probably go lower, but this is low enough to make most/all
software run well, removing frame drops. It's also low enough to get
emulators/mednafen to stop complaining in the console.
Set hw.wm*.txrx_workqueue=1 to use workqueue instead of softint.
The default value of hw.wm*.txrx_workqueue is 0, that is, use softint
as before.
ok by msaitoh@n.o.
If \*[title-section] is non-empty, use it to override the title
instead of appending it. Nothing in the tree uses title-section
currently, so it shouldn't affect any existing document.
This override will be used by the installation notes where the default
title is less than helpful.
