be set by a kernel conf option due to the struct buf structural
dependancy (sizing of b_pages[]) creating a conflict with modules
(which are not compiled with kernel config options overrides).
We'll be able to sysctl these two later on when the buffer subsystem
is revamped.
for the AN985 "Centaur" chip, which is apparently the next genetation
of the "Comet." The AN985 is also a tulip clone and is similar to the
AL981 except that it uses a 99C66 EEPROM and a serial MII interface
(instead of direct access to the PHY registers).
Also updated various documentation to mention the AN985 and created
a loadable module.
I don't think there are any cards that use this chip on the market yet:
the datasheet I got from ADMtek has boxes with big X's in them where the
diagrams should be, and the sample boards I got have chips without any
artwork on them.
It been awhile since the last major update, as a benefit there
are some cool things in this one (and new bugs probably :) )...
The ATA driver has grown "real" timeout support for all devices.
This means that it should be possible to get in contact with
(especially) lost ATAPI devices. It also means that the ATA
driver is now usable on notebooks as it will DTRT on resume.
An experimental hack at utilizing the Promise66's at UDMA66 is
in there, but I cant test it. If someone feels like sending
me one, give me a ping.
The ATAPI DMA enableling scheme has been changed, also better DMA
support for the Aladdin chipset has been implemented for ATAPI
devices. Note that the Aladdin apparently only can do DMA reads
on ATAPI devices, and the Promise cant do ATAPI DMA at all.
I have seen problems on some ATAPI devices that should be able
to run in DMA mode, so if you encounter problems with hanging
atapi devices during the probe, or during access, disable DMA
in atapi-all.c, and let me know. It might be nessesary to do this
via a "white list" for known good devices...
The ATAPI CDROM driver can now use eject/close without hanging and
the bug that caused reading beyond the end of a CD has been fixed.
Media change is also handled proberly. DVD drives are identified
and are usable as CDROM devices at least, I dont have the HW to
test this further, see above :).
The ATAPI tape driver has gotten some support for using the DSC
method for not blocking the IDE channel during read/write when
the device has full buffers. It knows about the OnStream DI-30
device, support is not completed yet, but it can function as a
primitive backup medium, without filemarks, and without bad media
handeling. This is because the OnStream device doesn't handle this
(like everybody else) in HW. It also now supports getting/setting
the record position on devices that supports it.
Some rather major cleanups and rearrangements as well (cvs -b diff
is your freind). I'm closing in on declaring this for beta code,
most of the infrastruture is in place by now.
As usual USE AT YOUR OWN RISK!!, this is still alpha level code.
This driver can hose your disk real bad if anything goes wrong, but
now you have been warned :)
But please tell me how it works for you!
Enjoy!

Revert the major number back to 2.
libcrypt only export one function, before the recent changes and now:
char *crypt(const char *key, const char *salt);
The prototype didn't changed. Internal representation of `char' and `char *'
didn't changed. Therefore, there is no reason to change the version number.

clustering issues (replacing code that used to be in
ufs/ufs/ufs_readwrite.c). vm_fault also now uses the new VM page counter
inlines.
This completes the changeover from vnode->v_lastr to vm_entry_t->v_lastr
for VM, and fp->f_nextread and fp->f_seqcount (which have been in the
tree for a while). Determination of the I/O strategy (sequential, random,
and so forth) is now handled on a descriptor-by-descriptor basis for
base I/O calls, and on a memory-region-by-memory-region and
process-by-process basis for VM faults.

submitter, who *still* hasn't bothered to answer me back.
The thing which the submitter completely failed to mention is that
his 3c900B-TPO card has the transceiver selection in the EEPROM set
to "auto." You can tweak the setting using the 3C90XCFG.EXE utility
that 3Com provides with the card. I'm not sure if it's supposed to
default to auto or if the user fiddled with it. Currently, the xl
driver only does autoselection for 10/100 NICs (i.e. those with NWAY
autonegotiation capabilities). For the 10baseT, 10base5, 10base2,
10baseFL and 100baseFX cards, the driver sets the default media to
whatever the EEPROM transceiver selector says. The problem is that
the "auto" selection is mistakenly identified as "10/100 NWAY
autoselection mode" and this is not handled correctly: the default
media ends up being chosen as 100baseTX, which doesn't work because
we've only added 10baseT media types to the ifmedia word. This leads
to a panic in ifmedia_set() (something else which the submitter never
bothered to mention).
A workaround for this is to re-run the 3C90XCFG.EXE utility and change
the transceiver selection to something besides "auto." I have also
patched the driver to watch for the "auto" setting in the non-miibus
case and select a reasonable default based on the card type instead of
falling through to 100baseTX and exploding.

Rename dev->si_bsize_max to si_iosize_max and set it in spec_open

Set vp->v_maxio from dev->si_bsize_max in spec_open rather than

spaces which cross a segment boundry in the page table. pmap_kextract()
is not designed for access to the user space portion of the page
table and cannot handle the null-page-directory-entry case.
The fix is to have vm_fault_quick() return a success or failure which
is then used to avoid calling pmap_kextract().
