For now these just pass through to the current softintr code.
(The naming is different to allow softint/softintr to co-exist for a while.
I'm hoping that should make it easier to transition.)
Always write entries to all IOAPIC pins. The first 16 pins are
threated as ISA IRQs by default, the others like PCI IRQs. This avoids
inconsistencies based on incomplete BIOS setups. This resulted in early
ACPI SCI notifications to be lost, effectively breaking the Embedded
Controller on cold start on many notebooks.
Don't special case the IOAPIC setup between ioapic_attach and
ioapic_enable, always setup the correct redirections. Depend on
splhigh/disable_intr to stop interrupts and don't keep them masked in
the IOAPIC. This avoids unacknowleged edge interrupts and fixing the problem
of broken PS/2 keyboard when hitting keys during early boot.
- Instead of hooking the handler on the specdev of a mounted file system
hook directly on the `struct mount'.
- Rename from `vn_cow_*' to `fscow_*' and move to `kern/vfs_trans.c'. Use
`mount_*specific' instead of clobbering `struct mount' or `struct specinfo'.
- Replace the hand-made reader/writer lock with a krwlock.
- Keep `vn_cow_*' functions and mark as obsolete.
- Welcome to NetBSD 4.99.32 - `struct specinfo' changed size.

IHAE "IP Header Alignment Enable" feature of RXC register;
- careful cross referencing at KSZ8692P/8841P/8842P PDFs indicates IHEA
bit works as follows; When the feature is turned on, Rx DMA engine
will populate Rx frame data in the Rx memory with +2 or +3 byte swifted
to make its IP head field 32bit aligned. The shift amount is recorded
inside RDES0 to tell 0, 2 or 3. The automatic alignment is done only
when IHAE is enabled _and_ the Rx frame was IP frame. In other cases,
RDES0 swift amount field keeps 0.
- KSZ8841P document mentions the IHAE bit but its reference link is broken
to tell the new RDES0 field. KSZ8842P lacks both. The bit usage of
RDES0 23:20 seems different from KSZ8692P, which brings me a vague
suspiction of documentation error.
envstat(8) and the envsys framework:
- Modify the ENVSYS_SETDICTIONARY ioctl to support the following
plist structure:
<dict>
<key>foo0</key>
<array>
<dict>
<key>index</key>
<string>sensor0</string>
<key>description</key>
<string>cpu temp</string>
...
Another property for this sensor
...
</dict>
...
Another dictionary for other sensor
...
</array>
...
Another device as above
...
</dict>
Multiple devices with multiple sensors can now be specified, that means
that to set the properties only one copyin(9) is needed now.
- Added the ENVSYS_REMOVEPROPS ioctl, that accepts a boolean object
"envsys-remove-props" and when set to true, all properties that were
set previously by ENVSYS_SETDICTIONARY will be removed. That means that
you can now set multiple critical limits, descriptions and all they
will be removed or changed to its default value (for rfact and
description objects).
- Added the 'index' and 'allow-rfact' objects into the sensor dictionaries,
for better interactivity with userland. To know the position of the
sensor and to know if sensor allows to change the rfact.
- Misc cosmetic changes for consistency.
- Use a two clause license for all my code.
at the same time and the code accessed to an unexistent dictionary:
- Rather than using a global dictionary, use a singly linked list to
access to the dictionaries, one per event.
- When the dictionary has been sent to userland, destroy it and remove
it from the list.
With that change it is possible to receive multiple events at the
same time without panics; again thanks to rmind@ for comments and help
with locking.

mpacpi.c 1.48.12.2 from jmcneill-pm:
Don't process the MADT and modify the interrupt config at one moment and
later trying to figure out if an entry was overriden and matches the
ACPI SCI. This is brain-dead and breaks in various situations.
Just check for each ISA override entry, if it matches the SCI. If it
does, remember it and use it for the interrupt setup. If there's no such
override assume that it is not changed, but override the polarity and
level from ISA settings to PCI settings.
When changing the redirection entry for an interrupt, write the
high 32bit first. The low 32bit contain the mask bit and removing
that before setting the destionation ID can lead to lost interrupts.
(it does but has a side-effect) or .text (which is probably ok, but
still less kosher).
Make section macros work for traditional cpp (I guess we haven't used
that for a *long* time, b/c it was broken).
Use __unused instead of explicit attribute for __COPYRIGHT (to be
changed in the next commit).
Define __KERNEL_COPYRIGHT in terms of __COPYRIGHT rather than
duplicating the logic and accidentally inverting it.
Results in identical obj tree for an i386 build modulo ar archives
(with timestamps embedded) and few .o files (and programs they are
part of) that embed timestamps as strings.
