All I/O APIC pins are masked when an I/O APIC is first probed. The
APIC enumerator (MP Table or MADT) then parses its associated tables to
configure individual pins to set custom delivery modes or alternate
routing (e.g. routing IRQ 0 to intpin 2). Pins for regular interrupt
pins are left masked until the first interrupt is assigned. However,
pins with unusual settings (e.g. NMI or SMI) are never assigned an
interrupt and thus never re-programmed. The I/O APIC code used to
reprogram all interrupt pins during registration but this was lost in
r151979.
In theory, this is mostly a no-op as the ACPI APIC table does not
include a way to enumerate NMI or SMI pins for the I/O APIC, so only
systems using an MP Table would be affected.

Using the device pager with /dev/kmem is not stable since KVA mappings
are transient, but the device pager caches the PA associated with a
given offset forever. Interestingly, mips' implementation of
memmap() already refused requests for /dev/kmem.
Note that kvm_read/kvm_write do not use mmap, but use read and write on
/dev/kmem, so this should not affect libkvm users.

etc. can find out where the SMBIOS entry point is located. In pure
UEFI mode the BIOS is not mapped into the standard address space so the
SMBIOS table might not appear between 0xf0000 and 0xfffff. The
UEFI environment can report this the location of the anchor. If it is
reported then expose it as hint.smbios.0.mem. This can then be used
by other tools. However, we should make smbios(4) useful and have it
take this value and provide accesor function so ipmi(4) etc. don't
have to parse and figure things about the SMBIOS table. I have some
simple patches to smbios(4) to expose this address as sysctl and
for ipmi(4) to get the base address. However, the real fix is to
have ipmi(4) ask smbios(4) for what it wants and have smbios(4)
parse it out and return it. This would make smbios(4) useful and reduce
duplicated code. If this address doesn't point to the anchor then
finding SMBIOS info. will fail as if this didn't exist. So there should
be no harm.
With this change and the following hack, dmidecode works on a bunch of
UEFI machines that I tested:
if kenv hint.smbios.0.mem > /dev/null
then
mkdir -p /sys/firmware/efi
mount -t tmpfs -o size=8k tmpfs /sys/firmware/efi
echo "SMBIOS=`kenv hint.smbios.0.mem`" > /sys/firmware/efi/systab
fi
Linux exposes this information via the /sys/firmware/efi/systab file which
dmidecode looks at. We should update dmidecode to do this the FreeBSD
way when we determine what that is!

received on a TCP session that has entered the ESTABLISHED state. This
results in a lot of calls to reset the keepalive timer.
This patch changes the behavior so we set the keepalive timer for the
keepalive idle time (TP_KEEPIDLE). When the keepalive timer fires, it will
first check to see if the session has been idle for TP_KEEPIDLE ticks. If
not, it will reschedule the keepalive timer for the time the session will
have been idle for TP_KEEPIDLE ticks.
For a session with regular communication, the keepalive timer should fire
approximately once every TP_KEEPIDLE ticks. For sessions with irregular
communication, the keepalive timer might fire more often. But, the
disruption from a periodic keepalive timer should be less than the regular
cost of resetting the keepalive timer on every packet.
(FWIW, this change saved approximately 1.73% of the busy CPU cycles on a
particular test system with a heavy TCP output load. Of course, the
actual impact is very specific to the particular hardware and workload.)

6988 spa_sync() spends half its time in dmu_objset_do_userquota_updates
Using a benchmark which creates 2 million files in one TXG, I observe
that the thread running spa_sync() is on CPU almost the entire time we
are syncing, and therefore can be a performance bottleneck. About 50% of
the time in spa_sync() is in dmu_objset_do_userquota_updates().
The problem is that dmu_objset_do_userquota_updates() calls
zap_increment_int(DMU_USERUSED_OBJECT) once for every file that was
modified (or created). In this benchmark, all the files are owned by the
same user/group, so all 2 million calls to zap_increment_int() are
modifying the same entry in the zap. The same issue exists for the
DMU_GROUPUSED_OBJECT.
We should keep an in-memory map from user to space delta while we are
syncing, and when we finish, iterate over the in-memory map and modify
the ZAP once per entry. This reduces the number of calls to
zap_increment_int() from "number of objects modified" to "number of
owners/groups of modified files".
This reduced the time spent in spa_sync() in the file create benchmark
by ~33%, from 11 seconds to 7 seconds.
