use a normal console to install on systems, such as my Tyan S2885,
which find the in-built vga in isa land rather than pci land.
Completes earlier work by Tom Cosgrove on GENERIC.

pending result. This isn't a good solution (we're obviously missing an
interrupt or two in some cases), but this will guarantee we get called
periodically until all of the queues are drained. Based on idea from
"jochen from penguin-breeder decimal org"; ok theo

superblock; make the block size check also catch negative values.

so that the "high" pri interrupt gets blocked by the "low" spl & irq handler,
and raise the cpl to the "high" level in the handler, so that no other
in fact lower-leveled, interrupts can preempt the handling of the "high"
interrupt. This means that the "low" interrupt gets the same quality treatment,
thus causing some degradation in performance. Therefore we still issue a
diagnostic, so people can try to avoid the situation by tweaking their BIOS
settings. Note, there is still issues with dynamically established interrupts
which cause irq sharing, we are working on that.

Also deal with mixed scsi/ide/whatever setups. Based on a diff from
Fred de Jong. OK deraadt@ and tested by several people.

function names in messages didnt always match the actual name of the function.
endian fix when dumping a qtd chain so it terminates correctly on big endian
archs.
dont blame uhci for problems ehci has.

log message for 1.175:
Tweak a debugging printf().
log message for 1.179:
Make one message dependent on ohcidebug, so it doesn't interfere with polled

hcpriv is not actually used here. Remove references to it.
|
|
Interrupt descriptors might become invalid while being processed in
uhci_check_intr - so remember their next pointer before calling it.
|
|
Ignore a CRCTO error on a SETUP transaction in combination with STALLED or NAK.
This fixes problems with the GL641.
|
|
Transfers should only be removed if they haven't already completed
|
|
The cancellation of the timeout in ohci_softintr should predicate on the
transfer being the last of the batch
|
|
It's possible that the ohci interrupt can reach the CPU before the write
over PCI. This results in the done head pointer being NULL. If the
subsequent read of the interrupt status indicates that an OHCI_WDH has
occured then the done pointer should be reread and the pointer nulled.

Avoid touching the xfer after calling usb_transfer_complete(), as the
driver callback may have recycled it. From PR 25960.

swap the order that two items are written; possibly fixes a race
condition that would affect isoc transfers.

log message for 1.142:
Fix a done list handling bug which exhibits under high shared interrupt
rate and bus traffic. As the interrupt register is read after checking
hcca_done_head, there was a small chance of dropping a done list.
Ignore OHCI_WDH interrupt bit if hcca_done_head is zero so that OHCI_WDH
is processed later.
log message for 1.147:
Failure to properly mask off UE_DIR_IN from the endpoint address was
causing OHCI_ED_FORMAT_ISO and EHCI_QH_HRECL to get set spuriously,
causing rather interesting lossage.

Update actlen even in the case where a TD returns an error -- this is
critical for the umass bulk-only STALL case.
