Add support for SPARC64 V (and where it already makes sense for other
HAL/Fujitsu) CPUs. For the most part this consists of fleshing out the
MMU and cache handling, it doesn't add pmap optimizations possible with
these CPU, yet, though.
With these changes FreeBSD runs stable on Fujitsu Siemens PRIMEPOWER 250
and likely also other models based on SPARC64 V like 450, 650 and 850.
Thanks go to Michael Moll for providing access to a PRIMEPOWER 250.
r207622:
Drop driver lock before exiting from interrupt handler.
r207623:
Make sure to check whether driver is running before processing
received frames. Also check driver has valid ifp pointer before
calling msk_stop() in device_shutdown handler. While I'm here
remove unnecessary accesses to interrupt mask registers in
device_shutdown handler because driver puts the controller into
reset state.
With these changes, msk(4) now survive from heavy RX traffic(1byte
UDP frame) while reboot is in progress.
r207638:
When VLAN hardware tagging is disabled, make sure to disable VLAN
checksum offloading as well as TSO over VLAN.
r207628:
Enable multi-descriptor transmisstion for fragmented mbufs. There
is no more need to defragment mbufs. After transmitting the
multi-fragmented frame, the controller updates only the first
descriptor of multi-descriptor transmission so it's driver's
responsibility to clear OWN bits of remaining descriptor of
multi-descriptor transmission. It seems the controller behaves much
like jme(4) controllers in descriptor handling.
r207635:
Free entire mbuf chain instead of the first mbuf.
- Remove dead code. Calculated greatest common divisor was not used at all.
- Prefer u_int32_t over unsigned int to make its intention more clearer.
- Move the function to a header file and make it a static inline function.
On sparc64 obtain the initiator ID to be used for SPI HBAs from the
Open Firmware device tree in order to match what the PROM built-in
driver uses. This is especially important when netbooting Fujitsu
Siemens PRIMEPOWER250 as in that case the built-in driver isn't used
and the port facts PortSCSIID defaults to 0, conflicting with the
disk at the same address.
- On sparc64 obtain the initiator ID from the Open Firmware device tree
in order to match what the PROM built-in driver uses.
- Remove some no longer used includes.
Don't bother enabling interrupts before we're ready to handle them. This
prevents the firmware of Fujitsu Siemens PRIMEPOWER250, which both causes
stray interrupts and erroneously enables interrupts at least when calling
SUNW,set-trap-table, from shooting itself in the foot.
Add OF_getscsinitid(), a helper similar to OF_getetheraddr() but for
obtaining the initiator ID to be used for SPI controllers from the
Open Firmware device tree.
r207545:
Fix wrong dma tag usage. Previously it used TX descriptor ring dma
tag which should be TX mbuf dma tag.
r207625:
Remove clearing RxHashTable2 register. The register is reprogrammed
in sge_rxfilter().
- Add a signal handler for SIGINT which removes output file when necessary.
- While I'm there, move unlink_input() slightly down to after closing the
output file, in uncompression path.
- Language improvements to make the BUGS section easier to read.
Update GRANDPARENTED text to match the contents of tzdata/factory r19879.
This eliminates "warning: time zone abbreviation differs from POSIX" on
installworld.
Spaces and various other characters in pathnames are not passed through
literally by xargs in its default mode. Instead, use find . -exec ... {} +
Although the -- argument is not strictly required here, add it anyway to
avoid surprises when modifying the code to find -f -somedir ...
Fix named-checkconf in the situation where named_chroot_autoupdate
is NOT set, but named_chrootdir IS set.
Remove required_files for named.conf, named-checkconf is enough.
n64 has a different size for KINFO_PROC_SIZE.

MFC r207152:
Move the constants specifying the size of struct kinfo_proc into
machine-specific header files. Add KINFO_PROC32_SIZE for struct
kinfo_proc32 for architectures providing COMPAT_FREEBSD32. Add
CTASSERT for the size of struct kinfo_proc32.
MFC r207269:
Style: use #define<TAB> instead of #define<SPACE>.
Make SATA XPT negotiate and enable some additional SATA features, such as:
- device initiated power management (some devices support only this way);
- Automatic Partial to Slumber Transition (more power saving);
- DMA auto-activation (expected to slightly improve performance).
More features could be added later, when hardware supports.
Revert r198705.
As scottl@ noticed, max_target/max_lun was intended to be only a hint for
existing bus scanner. Some FC/SAS SIMs report fake values there, that are
smaller then maximum supported IDs. In that case this check makes impossible
manual scan outside hinted range.
For ATA/SATA SIMs respective check was instead implemented at SIM level.
Newer SCSI SIMs expected to have these checks at driver or firmware level.
Some older SCSI SIMs have no this check and the issues will get back there.
Instead of catching SIGPIPE and jumping out of the signal handler with
longjmp, ignore it and handle write errors to the local output by exiting
from there. I have changed the error message to mention the local output
instead of NetBSD's wrong "Connection closed by foreign host". Write errors
to the network were already handled by exiting immediately and this now
applies to EPIPE too.
The code assumed that SIGPIPE could only be generated by the network
connection; if it was generated by the local output, it would longjmp out of
the signal handler and write an error message which caused another SIGPIPE.

r207409:
Both RX_GMF_LP_THR and RX_GMF_UP_THR must be 16 bits register. If
it is 8bits register then RX FIFO size can't exceed 2KB which is
not true for almost all Yukon II controller.
r207442:
Disable non-ASF packet flushing on Yukon Extreme as vendor's driver
does. Without this change, Yukon Extreme seems to generate lots of
RX FIFO overruns even though controller has available RX buffers.
These excessive RX FIFO overruns generated lots of pause frames
which in turn killed devices plugged into switch. It seems there is
still occasional RX frame corruption on Yukon Extreme but this
change seems to fix the pause frame storm.

Enable VLAN hardware tag insertion/stripping. Due to lack of SiS190
controller, I'm not sure whether this is also applicable to SiS190
so this feature is only activated on SiS191 controller.
In theory, controller reinitialization is not needed when VLAN tag
configuration is changed, but xclin said controller was not stable
whenever toggling VLAN tag bit. To address that, sge(4)
reinitialize controller for VLAN configuration which seems to work
as expected. VLAN tag information for TX/RX descriptor and
configure bit of RxMacControl register was found by xclin.

Enable FCS stripping and padding 10 bytes bit of RX MAC control
register. Due to lack of SiS190 controller, I'm not sure whether
this is also applicable to SiS190 so this feature is only activated
on SiS191 controller.
The controller can pad 10 bytes before DMAing a received frame to
RX buffer and received bytes include the padded bytes. This padding
is very useful on strict-alignment architectures because driver
does not have to copy received frame to align IP header on 4 bytes
boundary. It also gives better RX performance on non-strict
alignment architectures. Special thanks to xclin to give me
valuable register information. Without his enthusiastic trial and
errors this wouldn't be even possible.
While I'm here tighten validity check of received frame. Controller
clears RDS_CRCOK bit when it received bad CRC frames. xclin found
that using loop back testing.

r207375:
Preserve unknown bits of RX MAC control register when driver

is one of key registers to get various offloading features as well
as performance. Blindly clearing unrelated bits can result in
unexpected results.
