mycroft e63d9a6eae Restructure interrupt handling a little: 
* Only futz with the done list in the soft interrupt handler.  In the hard
  interrupt handler, do nothing except mask WDH and queue the soft interrupt.
  This simplifies a bunch of code, removes two O(n^2) queue manipulations,
  and gets rid of some really sketchy stuff around the queue head access.
* Use the auto-masking code at the end of the interrupt handler for both WDH
  and RHSC interrupts.  Again, this reduces the code a little, and avoids
  multiple writebacks to the chip registers.

joff 330c69ca0e Make sure to ack the interrupt even if we are ignoring it. Otherwise, we will 
keep coming back.

fvdl a3cea30b50 Implement an USB memory reserve. Allocate some memory per host controller 
in the wanted bus_dma space. If an allocation fails during operation
(i.e. when hotplugging an umass device), fall back to using the reserve.

The amount can be configured as USB_MEM_RESERVE. The default value is
256k.

Ideally, there would be a way to steal pages in the desired area from
UVM, but that's far more complicated, and this is not intrusive, plus
it works.

augustss d32a749096 Allow strings descriptor 0 to be fetched. It's the default language index. 2004-10-26 20:46:16 +00:00
mycroft 584d70dbc1 Avoid touching the xfer after calling usb_transfer_complete(), as the 
driver callback may have recycled it.  From PR 25960.

mycroft b48bbc8b8a Fix an error in a printf() format. 
Swap the order that two items are written; possibly fixes a race condition
that would affect isoc transfers.

mycroft ac575d2a58 Make one message dependent on ohcidebug, so it doesn't interfere with polled 
operation; e.g. when entering a root device or in DDB.

mycroft 7c3a6504d0 Adjust a couple of comments to make it clear WTF is going on. 2004-06-22 18:27:46 +00:00
mycroft 941901b304 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.

Suddenly I get MUCH better performance with ehci...

toshii 05069ebd4d Use the correct wValue to get hub desriptors. 
Also, make wValue checks of root hub codes less strict.

simonb 78c2103e34 Remove assigned-to but otherwise unused variables. 
Remove unreachable break after return statements.

toshii 6bd45c6229 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.

mycroft dad4d4580d Update actlen even in the case where a TD returns an error -- this is critical 
for the umass bulk-only STALL case.

simonb d7b879c6ec Grrr. So much for my ability to use grep(1) effectively. Pointed out 
by Stephen Degler in private mail.

Pointed out by SOMEYA Yoshihiko.

toshii 21318640e1 Update xfer->frlengths for input isoc transfer. Based on patches from 
SOMEYA Yoshihiko.
Also fix error handling for isoc transfer somewhat; usb_transfer_complete
shouldn't be called for more than once.
 2002-12-07 07:33:20 +00:00
toshii 44f269f8ff Fix several nits. Mostly from SOMEYA Yoshihiko. 
- Call usbd_transfer_complete at splusb.
- Fix a botched for loop in ohci_rem_ed.
- In ohci_close_pipe, wait 1ms after removing an ED to avoid possible race
 condition.

lukem 06de426449 SIMPLEQ rototill: 
- implement SIMPLEQ_REMOVE(head, elm, type, field).  whilst it's O(n),
  this mirrors the functionality of SLIST_REMOVE() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
  this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups
