disable multiword DMA for these chips. multiword DMA can be forced with
options PCIIDE_AMD756_ENABLEDMA on rev D2 chips, but use at your own risk !
While I'm there remove a duplicate allocation of sc_wdcdev.nchannels in HPT
code.
volatile flags (isp_mboxbsy- keeps a bitmask of expected output mailbox
registers) and storage for them (isp_mboxtmp). Get rid of macroized
LUN widths. This is determined at run time.
in new MBOX_WAIT_COMPLETE/MBOX_NOTIFY_COMPLETE macros (ready for SMPizing).
Define STRNCAT inline for our usage.
Stealing a bit of the xs_status flags to maintain command state that
is pertinent for the hBA- should really reserve them for private usage
in scsipiconf.h.
Qlogic controller driven by this chipset. If they don't want the verbosity,
don't compile a DIAGNOSTIC kernel.
Major amount of mailbox command rewrites- hopefully should fix some of the
outstanding PRs.
Change header to note that this is no longer maintained at NASA/Ames.
and loaded. Remember to enable interrupts after isp_reset but before
isp_attach. Return CMD_EAGAIN on request queue overflow so we can retry
the command when there's more queue space.
Some AMD controllers have a bug which can look up the machine when using DMA, so
disable DMA for some revisions (info provided by AMD).
"options PCIIDE_AMD756_ENABLEDMA" can be used to force DMA on these chips.
registers. rationale:
- Netwave cards choke if we map i/o memory to >= 0x400
- even though, CIS tuple talks nothing about it
- it is not possible to specify range in pcmcia_io_map
- it would be very bad to do a try-and-error bus_space allocation for
i/o memory regions < 0x400
- we can have exactly the same functionality with memory mapped access
this should correct PR 10139.
the memory mapped access idea was from WIDE wildboar/bsdi cnw code.
u_int8_t array to struct ieee80211_nwid to prepend length field.
The length field is necessary because IEEE 802.11 spec doesn't prohibit
even '\0' for SSID.
Though the name and the value of SIOC... macro is unchanged, this change
breaks binary compatibility. The only affected userland program on the
tree is ifconfig(8).
As Jason suggested on tech-net, it is better than live with problems
since there are no releases for this ioctls yet.
