them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.
- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.
This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
- split mkclock attachment from sparc64/clock.c into dev/mkclock.c
(now clock.s only contains clock interrupt and timecounter stuff)
- rename match/attach functions of rtc at ebus to match the device name
- update some comments around clock devices in GENERIC
No objection on port-sparc64 for a month.
on an Ultra 2 and works fine, apart from formatting which is known
to be broken. It failed to work on an ebus machine. The ebus
support compiles fine, but I don't have hardware for testing. This
code is based on the sparc driver with hints from OpenBSD on how
to do the sbus and ebus attachments, along with help from martin@
and mrg@.

TODO:
- fix ebus support
- fix XXX issues
- check resource deallocation
- fix formatting
- merge remaining differences from sparc driver
- split out back end chip support
- have sparc driver use new common back end chip support
- adapt to newlock when branch is ready
- adapt to "disk-info" property dictionary
the rules due to needing to conditionally postprocess the HAL object file.
Macppc needs a a non-ELF HAL (EABI) object, so take care of that by default
in the atheros include file.
* lpt device is defined in MI place (dev/ppbus/files.ppbus), dev/ic/lpt.c
is included there too; dev/ic/lpt.c is not included if ppbus is
configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt
glue
- factor out disksubr.c between sun3, sparc and sparc64. Keep the sun3
groveling code to find a NetBSD disklabel in the first sector (so that it
can find a label at the old sun3 LABELOFFSET) as a fallback is not
label at LABELOFFSET, or sun label is present.
- Fix the sun3 LABELOFFSET (was 64, but the kernel wrote the NetBSD label at
128)
- Make next68k disksubr.c always write a next-compatible disklabel.
- remove #ifdef __sparc__ hack from disklabel(8), and change it to issue
a DIOCWDINFO after writing the disklabel to the raw partition in the
-r/-I case (so that the kernel can convert the label if needed).
- Switch rtc (M5819) routines to use MI mc146818(4) driver.
Tested on Ultra5 (mkclock_ebus), but mkclock_sbus and rtc_ebus are not tested.
XXX This file should be split into each device and each bus attachment,
XXX and moved into sys/arch/sparc64/dev or sys/dev/sun.
/dev/power.
XXX - due to the way interrupt handling is structured we have no easy
way to defer clearing the button interrupt until the sysmon callback
has happened and the event is dispatched. We clear it imediately on
return from the interrupt handler. This means we get an interrupt storm
until the button is released, and then start to handle it.
This needs to be fixed! (But with the default application for the power
button does not make a user visible difference.)
This is derived from alpha/microtime.c and i386/tsc_microtime.c,
and will share with both ports.
This should fix PR port-sparc64/18452.

children to attach; it is not sufficient to have an interface
atttribute which only happens to have the same name.
Fix the same mistake with the sabtty declaration.
