This driver only supports 10Mb Ethernet using PIO (the hardware supports
DMA, but the driver only does PIO).  There are not any PCCard adapters
supported by this driver, only ISA cards.  In addition, it does not use
bus_space but instead uses bcopy with volatile pointers triggering a
host of warnings.  (if_ie.c is one of 3 files always built with

This hardware is not present on any modern systems.  The driver is quite
hackish (raw inb/outb instead of bus_space, and raw inb/outb to random
I/O ports to enable ACPI since it predated proper ACPI support).

The wl(4) driver supports pre-802.11 PCCard wireless adapters that
are slower than 802.11b.  They do not work with any of the 802.11
framework and the driver hasn't been reported to actually work in a
long time.

While this driver does do DMA, it bounce buffers all transactions through
a single 64k buffer.  It also does not have a manpage.

The si(4) driver supported multiport serial adapters for ISA, EISA, and
PCI buses.  This driver does not use bus_space, instead it depends on
direct use of the pointer returned by rman_get_virtual().  It is also
still locked by Giant and calls for patch testing to convert it to use
bus_space were unanswered.

Using a benchmark which has 32 threads creating 2 million files in the
same directory, on a machine with 16 CPU cores, I observed poor
performance. I noticed that dmu_tx_hold_zap() was using about 30% of
all CPU, and doing dnode_hold() 7 times on the same object (the ZAP
object that is being held).

dmu_tx_hold_zap() keeps a hold on the dnode_t the entire time it is
running, in dmu_tx_hold_t:txh_dnode, so it would be nice to use the
dnode_t that we already have in hand, rather than repeatedly calling
dnode_hold(). To do this, we need to pass the dnode_t down through
all the intermediate calls that dmu_tx_hold_zap() makes, making these
routines take the dnode_t* rather than an objset_t* and a uint64_t
object number. In particular, the following routines will need to have
analogous *_by_dnode() variants created:


This can improve performance on the benchmark described above by 100%,
from 30,000 file creations per second to 60,000. (This improvement is on
top of that provided by working around the object allocation issue. Peak
performance of ~90,000 creations per second was observed with 8 CPUs;
adding CPUs past that decreased performance due to lock contention.) The
CPU used by dmu_tx_hold_zap() was reduced by 88%, from 340 CPU-seconds
to 40 CPU-seconds.

zap_lockdir() / zap_unlockdir() should take a "void *tag" argument which
tags the hold on the zap. This will help diagnose programming errors
which misuse the hold on the ZAP.
