rig a PREPEND macro for ALTQ as the POLL/DEQUEUE semantic is very bad in
terms of locking. We make this a full functional queue to allow "bulk
dequeue" which will further reduce the locking overhead (for non-altq
enabled devices). Drivers will access this via the following macros, which
will show up in <net/if_var.h> once we expose ALTQ to the build:
IFQ_DRV_DEQUEUE(ifq, m) - takes a mbuf off the queue (driver queue first)
IFQ_DRV_PREPEND(ifq, m) - pushes a mbuf back to the driver queue
IFQ_DRV_PURGE(ifq) - drops all packets in both queues
IFQ_DRV_IS_EMPTY(ifq) - checks for pending mbufs in either queue
One has to make sure that the first three are protected by a driver mutex.
At the moment most network drivers still require Giant, so this is not an
issue. Even those that have thier own mutex usually hold it in if_start and
the like, so this requirement is almost always satisfied.
This evolved from a discussion with Andrew Gallatin.
- add locking
- disable ALTQ3_COMPAT by default (do not remove the code to keep the diff
towards KAME small)
- put some more code under ALTQ3 conditional compilation as it should be
- account for if_xname
- some more minor compile fixes
As people started wondering:
The strange path layout "altq/altq" is there to avoid "-Isys/contrib" and
make it "-Isys/contrib/altq" instead, as we will need at least <altq/altq.h>
and <altq/if_altq.h> for kernel compilation.
The "freebsd4_..." in the privious commit is just the best tag name in the
KAME tree I could find to classify this in order to track its history. It
does *not* mean that this will go to 4-STABLE or anything of that kind.
HEAD at this point). This will not exactly live in a vendor branch, but have
the vendor backing to make it easier to exchange diffs.
This will be followed by a diff which takes most of the .c files off the
vendor branch in order to:
- add locking
- disable ALTQ3_COMPAT code (which is outdated and "un-lockable")
There is work in progress to refine the configuration API. Import this "as
is" now to have more exposure time before 5-STABLE.
This is only the import, it will be some more days until you will actually
be able to compile ALTQ support into your kernel so don't hold your breath.
HEADUPs will be posted on current@ and net@ before this is actually enabled.

emulate its buggy ACPI support.) Our ACPI support is similar to Win2k,
also. Put this behavior under ACPICA_PEDANTIC so we can get back to our
previous behavior for OSV testing.

for a long time and is run in production use. This is the code present in
portversion 2.03 with some additional tweaks.
The rather extensive diff accounts for:
- locking (to enable pf to work with a giant-free netstack)
- byte order difference between OpenBSD and FreeBSD for ip_len/ip_off
- conversion from pool(9) to zone(9)
- api differences etc.

Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.
Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.
Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.
Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.
Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.
Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:
The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT
A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.
Manual page update to follow shortly.
