Almost all regression tests are based on very flexible fstest tool.
They verify correctness (POSIX conformance) of almost all file
system-related system calls.
The motivation behind this work is my ZFS port and POSIX, who doesn't
provide free test suites.
Runs on: FreeBSD/UFS, FreeBSD/ZFS, Solaris/UFS, Solaris/ZFS

PCI bus' one as the default one, and explicitely use the other one for
non-PCI devices.
This is needed because the PCI bus can only address 64MB of RAM, while some
IXP425 boards have 128MB or more, and most of the PCI drivers do not bother
providing the parent dma tag.
- Add a default parent dma tag, similar to what has been done for sparc64.
- Before invalidating the dcache in POSTREAD, save the bits which are in the
same cachelines than our buffers, but not part of it, and restore them after
the invalidation.

of keeping the write speed constant. And yes, that helps a lot

improvements using benchmarks/bonnie.

bus hanging off from the Fireplane/Safari bus in some USIII machines.
This is part 3/4 of allowing creator(4) to work in these machines.
The little info needed on how to configure the bridge and to work
around the incorrect values contained in the `interrupts' properties
of its children were obtained form OpenSolaris.
The separate bus front-end was inherited from the OpenBSD creator(4),
which at that time had a mainbus(4) (for USI/II machines, which use
an UPA interconnection bus as the nexus) and an upa(4) (for USIII
machines, which use a subordinate/slave UPA bus hanging off from the
Fireplane/Safari interconnection bus) front-end. With FreeBSD and
newbus there is/will be no need to have two separate bus front-ends
for these busses, so we can easily coallapse the shared front-end
and the back-end into a single source file (note that the FreeBSD
creator_upa.c was misnomer anyway; based on what it actually attached
to that should have been creator_nexus.c), actually OpenBSD meanwhile
also has moved to a shared front-end and a single source file. Due
to the low-level console support creator.c also wasn't free from bus
related things before.
While at it, also split sys/sparc64/creator/creator.h into a
sys/dev/fb/creatorreg.h that only contains register macros and move
the structures to the top of sys/dev/fb/creator.c as suggested by
style(9) so creator(4) is no longer scattered over two directories.
- Use OF_decode_addr()/sparc64_fake_bustag() to obtain the bus tags and
handles for the low-level console support instead of hardcoding
support for AFB/FFB hanging off from nexus(4) only. This is part 2/4
of allowing creator(4) to work in USIII machines (which have a UPA
bus hanging off from the Fireplane/Safari bus reflected by the nexus),
which already makes it work as the low-level console there.
- Allocate resources in the bus attach routine regardless of whether
creator(4) is used as for the low-level console and thus the required
bus tags and handles have been already obtained or not so the resources
are marked as taken in the respective RMAN.
- For both obtaining the bus tags and handles for the low-level console
support as well as allocating the corresponding resources in the
regular bus attach routine don't bother to get all for the maximum of
24 register banks but only (for) the two tag/handle pairs required for
providing the video interface for syscons(4) support. If we can't
allocate the rest of them just limit the memory range accessible via
creator_fb_mmap() accordingly.
- Sanity check the memory range spanned by the first and last resources
and the resources in between as far as possible, as the XFree86/Xorg
sunffb(4) expects to be able to access the whole region, even though
the backing resources are actually non-continuous. Limit and check
the memory range accessible via creator_fb_mmap() accordingly.
- Reduce the size of buffers for OFW properties to what they actually
need to hold.
- Rename some tables to creator_<foo> for consistency.
- Also for the sizes in the creator_fb_mmap() mapping table entries use
macros for consistency, add macros for the remaining register banks
for completeness.
nexus (which might or might not reflect an UPA interconnection bus;
accordingly UPA_BUS_SPACE should be renamed to NEXUS_BUS_SPACE at a
later point) and subordinate/slave UPA busses. This is part 1/4 of

operation as it ran out of free descriptors or if there are too many
segments in the first place, call bus_dmamap_unload() in order to
unload the already loaded segments.
For trying to map the defragmented mbuf (chain) in re_encap() this
introduces re_dma_map_desc() setting arg.rl_maxsegs to 0 as a new
failure mode. Previously we just ignored this case, corrupting our
view of the TX ring.
o In re_txeof():
- Don't clear IFF_DRV_OACTIVE unless there are at least 4 free TX
descriptors. Further down the road re_encap() will bail if there
aren't at least 4 free TX descriptors, causing re_start() to
abort and prepend the dequeued mbuf again so it makes no sense
to pretend we could process mbufs again when in fact we won't.
While at it replace this magic 4 with a macro RL_TX_DESC_THLD
throughout this driver.
- Don't cancel the watchdog timeout as soon as there's at least one
free TX descriptor but instead only if all descriptors have been
handled. It's perfectly normal, especially in the DEVICE_POLLING
case, that re_txeof() is called when only a part of the enqueued
TX descriptors have been handled, causing the watchdog to be
disarmed prematurely.
o In re_encap():
- If m_defrag() fails just drop the packet like other NIC drivers
do. This should only happen when there's a mbuf shortage, in which
case it was possible to end up with an IFQ full of packets which
couldn't be processed as they couldn't be defragmented as they
were taking up all the mbufs themselves. This includes adjusting
re_start() to not trying to prepend the mbuf (chain) if re_encap()
has freed it.
- Remove dupe initialization of members of struct rl_dmaload_arg to
values that didn't change since trying to process the fragmented
mbuf chain.
While at it remove an unused member from struct rl_dmaload_arg.
o In re_start() remove a abandoned, banal comment. The corresponding
code was moved to re_attach() some time ago.
With these changes re(4) now survives one day (until stopped) of
hammering out packets here.

- Retire the PCI_SUB*_1 constants and don't try to read a subvendor ID out
of them. There isn't a standard subvendor ID field for PCI-PCI bridges.
Instead, the dword at offset 0x34 is actually mostly reserved except for
the LSB which is the capabilities pointer.
