riastradh | Factor out HCI-independent xfer completion logic.
New API for HCI drivers to synchronize hardware completion
interrupts, synchronous aborts, and asynchronous timeouts:
- When submitting an xfer to hardware, call
usbd_xfer_schedule_timeout(xfer).
- On HCI completion interrupt for xfer completion:
if (!usbd_xfer_trycomplete(xfer))
return; /* timed out or aborted, ignore it */
- In upm_abort methods, call usbd_xfer_abort(xfer).
For HCI drivers that use this API (not needed in drivers that don't,
or for xfers like root intr xfers that don't use it):
- New ubm_abortx method serves role of former *hci_abort_xfer, but
without any logic for wrangling timeouts/callouts/tasks -- caller
in usbd_xfer_abort has already handled them.
- New ubm_dying method, returns true if the device is in the process
of detaching, used by the timeout logic.
Converted and tested:
- ehci
- ohci
Converted and compile-tested:
- ahci (XXX did this ever work?)
- dwc2
- motg (XXX missing usbd_xfer_schedule_timeout in motg_*_start?)
- uhci
- xhci
Not changed:
- slhci (sys/dev/ic/sl811hs.c) -- doesn't use a separate per-xfer
callout for timeouts (XXX but maybe should?)
- ugenhc (sys/rump/dev/lib/libugenhc/ugenhc.c) -- doesn't manage its
own transfer timeouts
- vhci -- times transfers out only on detach; could be adapted easily
if we wanted to use the xfer->ux_callout

skrll | Adapt the Synopsys DWC2 driver to NetBSD.
Still work-in-progress

skrll | First pass at netbsd-7 updated with USB code from HEAD
|
| 1.3.12.11 |
| 30-Apr-2016 |
skrll | Move the struct usb_task to struct usbd_xfer for everyone to use.

| 1.3.12.7 |
| 22-Oct-2015 |
skrll | Simplify *_XFER2SC using ux_bus
|
| 1.3.12.6 |
| 11-Oct-2015 |
skrll | Update ubm_allocx with the isoc frame count parameter and use it in
dwctwo(4)
|
| 1.3.12.5 |
| 06-Jun-2015 |
skrll | Sync with HEAD
|
| 1.3.12.4 |
| 19-Mar-2015 |
skrll | Do the same as OpenBSD and get rid of the *_handle typedefs and use
plain structures insteads
|
| 1.3.12.3 |
| 04-Dec-2014 |
skrll | Rework roothub control transfers so that much of the code is shared
across HCDs.
I have retained the vendor/product reporting for each HCD for now,
but it maybe get removed later.
ahci(4) now reports a language table and uses the usb_makestrdesc
function instead of rolling its own version.
|
| 1.3.12.2 |
| 03-Dec-2014 |
skrll | The grand renaming of structure members.
No functional change.
|
| 1.3.12.1 |
| 02-Dec-2014 |
skrll | Step #1 of memory allocation re-organisation.
Centralised the buffer allocation routine which now supports DMA
and non-DMA capable host controllers. Remove the
ubm_{alloc,free}m methods from usbd_bus_methods.
The buffer allocation is only allowed in thread context and,
therefore, negates the usefulness of the reserve dma code which
is removed in this change.
USBD_NO_COPY is also no longer required as usbd_transfer and
usbd_transfer_complete now track buffer usage and handle any
copying.

Merge netbsd-7-nhusb:
- API / infrastructure changes to support memory management changes.
- Memory management improvements and bug fixes.
- HCDs should now be MP safe
- conversion to KERNHIST based debug
- FS/LS isoc support on ehci(4).
- conversion to kmem(9)
- Some USB 3 support - mostly from Takahiro HAYASHI (t-hash).
- interrupt transfers now get proper DMA operations
- general bug fixes
- kern/48308
- uhub status notification improvements
- umass(4) probe fix (applied to HEAD already)
- ohci(4) short transfer fix
- Change the SOFTINT level from NET to SERIAL for the USB softint handler.
This gives the callback a chance of running when another softint handler
at SOFTINT_NET has blocked holding a lock, e.g. softnet_lock and most of
the network stack.
- kern/49065 - ifconfig tun0 ... sequence locks up system / lockup:
softnet_lock held across usb xfr
- kern/50491 - unkillable wait in usbd_transfer while using usmsc0
on raspberry pi 2
- kern/51395 - USB Ethernet makes xhci hang
- Various improvements to slhci(4)
- Various improvements to dwc2(4)

Teach usb_rem_task to return whether removed from queue or not.
New function usb_task_pending for diagnostic assertions.
Usable only for negative diagnostic assertions:
KASSERT(!usb_task_pending(dev, task))
If you can think of a better name for this than !usb_task_pending,
I'm all ears.
-
Nothing guarantees xfer's timeout has completed.
Wait for it when we free the xfer.
-
New xfer state variables ux_timeout_set and ux_timeout_reset.
These are needed because:
- The host controller interrupt cannot wait for the callout or task
to finish running.
- Nothing in the USBD API as is waits for the callout or task to
finish running.
- Callers expect to be able to resubmit USB xfers from xfer callbacks
without waiting for anything to finish running.
The variable ux_timeout_set can be used by a host controller to
decide on submission whether to schedule the callout or to ask an
already-scheduled callout or already-queued task to reschedule the
callout, by setting the variable ux_timeout_reset to true.
When the callout or task runs and sees that ux_timeout_reset is true,
rather than queue the task or abort the xfer, it can instead just
schedule the callout anew.
-
Fix steady state of timeouts in ehci.
This is complicated because:
1. There are three ways that an xfer can be completed:
(a) hardware interrupt completes xfer
(b) software decision aborts xfer with USBD_CANCELLED
(c) timeout aborts xfer with USBD_TIMEOUT
2. The timeout abort can't be done in callout because ehci_sync_hc,
called unconditionally by ehci_abort_xfer to wait until the device
has finished using any references to the xfer, may sleep. So we
have to schedule a callout that, when run, will schedule a usb_task.
3. The hardware completion interrupt can't sleep waiting for a callout
or task to finish -- can't use callout_halt or usb_rem_task_wait.
So the callout and usb_task must be able to run _after_ the hardware
completion interrupt, and recognize that they're late to the party.
(Note, though, that usbd_free_xfer does wait for the callout and
task to complete, so there's no danger they may use themselves after
free.)
4. The xfer may resubmitted -- and the timeout may be rescheduled --
immediately after the hardware completion interrupt, _while_ the
callout and/or usb_task may still be scheduled. Specifically, we
may have the following sequence of events:
(a) hardware completion interrupt
(b) callout or usb_task fires
(c) driver resubmits xfer
(d) callout or usb_task acquires lock and looks around dazed and
bewildered at the firehose of events like reading the news in 2019
The mechanism for sorting this out is that we have two bits of state:
- xfer->ux_timeout_set informs the driver, when submitting an xfer and
setting up its timeout, whether either the callout or usb_task is
already scheduled or not.
- xfer->ux_timeout_reset informs the callout or usb_task whether it
should reschedule the callout, because the xfer got resubmitted, or
not.
-
Factor out HCI-independent xfer completion logic.
New API for HCI drivers to synchronize hardware completion
interrupts, synchronous aborts, and asynchronous timeouts:
- When submitting an xfer to hardware, call
usbd_xfer_schedule_timeout(xfer).
- On HCI completion interrupt for xfer completion:
if (!usbd_xfer_trycomplete(xfer))
return; /* timed out or aborted, ignore it */
- In upm_abort methods, call usbd_xfer_abort(xfer).
For HCI drivers that use this API (not needed in drivers that don't,
or for xfers like root intr xfers that don't use it):
- New ubm_abortx method serves role of former *hci_abort_xfer, but
without any logic for wrangling timeouts/callouts/tasks -- caller
in usbd_xfer_abort has already handled them.
- New ubm_dying method, returns true if the device is in the process
of detaching, used by the timeout logic.
Converted and tested:
- ehci
- ohci
Converted and compile-tested:
- ahci (XXX did this ever work?)
- dwc2
- motg (XXX missing usbd_xfer_schedule_timeout in motg_*_start?)
- uhci
- xhci
Not changed:
- slhci (sys/dev/ic/sl811hs.c) -- doesn't use a separate per-xfer
callout for timeouts (XXX but maybe should?)
- ugenhc (sys/rump/dev/lib/libugenhc/ugenhc.c) -- doesn't manage its
own transfer timeouts
-
Fix steady state of root intr xfers.
Why?
- Avoid completing a root intr xfer multiple times in races.
- Avoid potential use-after-free in poll_hub callouts (uhci, ahci).
How?
- Use sc->sc_intr_xfer or equivalent to store only a pending xfer
that has not yet completed -- whether successfully, by timeout, or
by synchronous abort. When any of those happens, set it to null
under the lock, so the xfer is completed only once.
- For hci drivers that use a callout to poll the root hub (uhci, ahci):
. Pass the softc pointer, not the xfer, to the callout, so the
callout is not even tempted to use xfer after free -- if the
callout fires, but the xfer is synchronously aborted before the
callout can do anything, the xfer might be freed by the time the
callout starts to examine it.
. Teach the callout to do nothing if it is callout_pending after it
has fired. This way:
1. completion or synchronous abort can just callout_stop
2. start can just callout_schedule
If the callout had already fired before (1), and doesn't acquire
the bus lock until after (2), it may be tempted to abort the new
root intr xfer just after submission, which would be wrong -- so
instead we just have the callout do nothing if it notices it has
been rescheduled, since it will fire again after the appropriate
time has elapsed.
-
Initialize xfer->ux_status in uhci_root_intr_start.
Otherwise, it will be USBD_NOT_STARTED, so usbd_ar_pipe will skip
calling upm_abort.
Candidate fix for PR kern/54963, same problem as reported at:
href="https://mail-index.NetBSD.org/current-users/2020/02/13/msg037740.html
-
Set ux_isdone in uhci_poll_hub for DIAGNOSTIC.
-
Fix mistakes in previous sloppy change with root intr xfers.
- Make sure ux_status is set to USBD_IN_PROGRESS when started.
Otherwise, if it is still in flight when we abort the pipe,
usbd_ar_pipe will skip calling upm_abort.
- Initialize ux_status under the lock; in principle a completion
interrupt (or a delay) could race with the initialization.
- KASSERT that the xfer is in progress when we're about to complete
it.
Candidate fix for PR kern/54963 for other HCI drivers than uhci.
ok nick
ok phone
(This is the change that nick evidently MEANT to ok when he ok'd the
previous one!)
-
Fix build
-
Fix non-DIAGNOSTIC builds.
-
Fix wrong KASSERT in motg abort.
This has been wrong since last summer when we did the transition to
xfer->ux_status = USBD_CANCELLED earlier.
XXX pullup-9
-
Fix mistakes in timeout/abort/completion changes in motg(4).
- Call usbd_xfer_schedule_timeout so we actually do time out.
- Don't call usbd_xfer_trycomplete until all the data have been
transferred -- it commits to completion, not timeout.
- Use xfer->ux_status != USBD_IN_PROGRESS to test whether, after a
partial write, an xfer has been interrupted or timed out and need
not be continued.
- Remove wrong assertion.
-
Fix mistake in use of usbd_xfer_schedule_timeout in motg.
This code path is used both for xfers that are new, and xfers that
are being done piece by piece and are partway done. For the latter
case, skip usbd_xfer_schedule_timeout so we schedule it only once per
xfer.
-
Simplify some branches and kassert some redundant assignments.
