 1.36  03-Mar-2022  riastradh usb: usbd_abort_pipe never fails. Make it return void.

Prune dead branches as a result of this change.
 1.35  14-Mar-2020  christos revert the 0x% -> %# change for fixed width formats pointed out by uwe.
 1.34  13-Mar-2020  christos PR/55068: sc.dying: Fix printf formats:
- no %s/%p for kernel log
- 0x% -> %#
- always %j for kernel log
 1.33  01-Dec-2019  maxv localify
 1.32  05-May-2019  mrg remove explicit 'extern struct cfdriver <my>_cd;' and use ioconf.h
 1.31  03-Sep-2018  riastradh Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

PR kern/52931 Kernel panics with Atheros usb wireless interface

Audit the flags to usbd_create_xfer so that USBD_FORCE_SHORT_XFER is
supplied wherever such a transfer is setup. We can drop
USBD_SHORT_XFER_OK as it has not bearing on number of TDs
 1.29  01-Jun-2017  chs branches: 1.29.2;
remove checks for failure after memory allocation calls that cannot fail:

kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

 1.27  20-Aug-2016  jdolecek extract crc16 code from utoppy driver to a separate file in libkern, for use
by ext2fs; every usage gets their own copy of the table for now, as it's
fairly small, and too rare to be used to be useful pulling into every kernel

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.
 1.23  16-Mar-2014  dholland branches: 1.23.2;
Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
 1.22  30-Aug-2013  skrll Remove race introduced by using usbd_sync_transfer_sig with a callback
that use the xfer cv (or does wake up on the xfer). The xfer has likely
been freed or re-used.

While here update utoppy(4) to use usbd_sync_transfer_sig.

Fixes PR/48151
 1.21  27-Oct-2012  chs branches: 1.21.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.20  10-Jun-2012  mrg branches: 1.20.2;
merge the jmcneill-usbmp branch. many thanks to jared for the
initial work, and every one else who has tested things for me.
this is largely my fault at this point :-)

the main changes are something like:

- usbd_bus_methods{} gains a get_lock() to enable the
host controller to provide a lock for the USB code.
if the lock isn't provided, old-style protection is
(partially) applied.

- ehci/ohci/uhci have been converted to the new
interfaces, including mutex/cv/etc conversion.

- usbdivar.h contains a discussion about locking and
what locks are held for which method calls. more
to come for usbdi(9) here.

- audio drivers (uaudio, umidi, auvitek) have been
properly SMPified now that USB is ready.

- scsi drivers have been modified to take the kernel
lock explicitly before calling into scsi code.

- usb pipes are associated with a lock, that is the
same as the controller lock. (this could be split
up further in the future.)

- several usbfoo_locked() or usbfoo_unlocked()
functions have been added to the usbdi(9) to
enable functionality with or without the USB
lock (per controller) already being held.

the TODO.usbmp file has specific details on what is left to
do, including what device-specific changes should be done now
that the whole framework is ready.
 1.19  11-Mar-2012  mrg minor cleanups from usbmp:
- move usbd_delay_ms() into usbdivar.h in the usb_subr.c section
- minor rcsid fixes
- copyright maintenence
 1.18  06-Mar-2012  mrg pull down from usbmp branch:

- rename usb_detach_{wake,waitup}() to usb_detach_{wake,waitup}old()
- use some c99 struct .initialisers
 1.17  23-Dec-2011  jakllsch Revert previous due to active usbmp branch(es).

Stop using the compatibility macros USB_ATTACH(), USB_DETACH(),
USB_MATCH(), et cetera. These files produce the same assembly
(according to objdump -d) before and after the change
 1.14  06-Dec-2009  dyoung branches: 1.14.2; 1.14.4;
Simplify device-activation hooks.
 1.13  23-Sep-2009  plunky fix up USB drivers printing of autoconf information

1. expand the USB_ATTACH_SETUP macro (requested by jmcneill)

2. reorder the attach function so that the first thing it does is print
newlines.

3. after this, we can call usbd_devinfo_alloc(), which polls the device
allowing a context switch, and aprint_normal() the device information.

this avoids problems where autoconf messages are getting mixed up.
 1.12  24-May-2008  cube Split device_t and softc for all USB device drivers, and related cosmetic
changes.

Matthias Drochner kindly reviewed this patch, and tested ums, ubt, uaudio
and ral. I tested umass myself.
 1.11  28-Apr-2008  martin branches: 1.11.2;
Remove clause 3 and 4 from TNF licenses
 1.10  13-Mar-2007  drochner branches: 1.10.32; 1.10.34; 1.10.36;
Introduce different autoconf interface attributes for USB drivers
matching (and handling) a whole device and those which match an
interface only. This will allow to enforce some rules, eg that
the former don't use interface information for matching or that the
latter don't modify global device state.
The previous way left too much freedom do the drivers which led to
inconsistencies and abuse.
For now, I've not changed locators and submatch rules, this will
happen later.
There should not be any change in behaviour, except in the case of
some drivers which did behave inconsistently:
if_atu, if_axe, uep: matched the configured device in the interface
stage, but did configuration again. I've converted them to match
in the device stage.
ustir, utoppy: matched in the interface stage, but only against
vendor/device information, and used any configuration/interface
without checking. Changed to match in device stage, and added
some simple code to configure and use the first interface.
If you have one of those devices, please test!

Add a kernel driver and userland program for the Topfield TF5000PVR range
of digital video recorders popular in Europe and Australia.

These devices have a USB client port which can be used to upload and

 1.8.10.1  22-May-2007  itohy Overhaul of USB stack, mostly DMA related

This applies to NetBSD 4.99.13 (March 1, 2007)

usbdi(9) interface is based on FreeBSD version, excluding
- removal of portability code

Patch most NetBSD changes, excluding
- DMA memory "reserve", since we don't need contiguous buffers any longer
- volatiles in DMA structure, since it should not be needed
with proper bus_dmamap_sync(9)s

DMA/non-DMA memory management overhaul
- Move all DMA related code to usb_mem.[ch]
(add usb_alloc_buffer_dma(), usb_free_buffer_dma(), etc.).
XXX Should usb_mem.[ch] be renamed as usb_mem_dma.[ch] ?
- Add corresponding non-DMA code to usb_mem_nodma.[ch] .
Currently just use malloc(9).
- Above files are conditionally used by config framework (added
attributes to conf/files and dev/usb/files.usb).
- Add diagnostic panics when resource allocation is requested
on interrupt context.
- Change memory allocations (that require context) from NOWAIT to WAITOK.

Allocate DMA/non-DMA buffer per host interface, not globally.
advantage: Buffers can be freed on detaching host interface.
Activity of a host interface does not affect others.
disadvantages: It possibly consumes more memory.

API changes
- usbd_alloc_xfer() is changed:
old: usbd_xfer_handle usbd_alloc_xfer(usbd_device_handle dev);
new: usbd_xfer_handle usbd_alloc_xfer(usbd_device_handle dev,
usbd_pipe_handle pipe);
- pipe argument of usbd_setup_*xfer() are now unused
XXX the pipe argument should be removed?
- add mapping APIs
- async request will be processed as a task (kernel thread context),
and delayed to some extent
- usbdivar.h: struct usbd_xfer: renamed a member "allocbuf" to "hcbuffer"
(mapped/allocated/refered buffer for HCI driver)
- usb_port.h: change usb_proc_ptr from struct ptoc * to struct lwp *
- usb_port.h: add usb_sigproc_ptr for psignal(9) (struct proc *)
- usb.h: add UE_MAXPKTSZ(ep) and UE_MAXPKTSZ_MASK macros for USB 2.0

changes to USB device drivers
- atu, aue, axe, cdce, cue, kue, rum, udav, upl, ural, url,
uaudio, ubt, ucom, ugen, uhidev, uirda, ulpt, umidi, urio,
uscanner, ustir, utoppy:
* catch up API change of usbd_alloc_xfer()
- umass, usscanner:
* catch up API change of usbd_alloc_xfer()
* eliminate memory copy for large transfer

ohci
- free resources on detach
- add lots of bus_dmamap_sync() operations
- simplify the code of loading std chain
- rewrite code of looking up TD/ITD from DMA addr by using allocation chunk
- add workaround for CMD Tech 670 and 673 chipsets
- make sure resources are not allocated in interrupt context
- add support for mapping buffer and mbuf

slhci
- allocate xfer and slhci_xfer at once, and simplify relevant code
- add slhci_detach()
- remove second arg of slhci_attach() since it is the same as the first arg.
- add support for "mapping" (no, it doesn't map since it doesn't do DMA)
buffer and mbuf
- add pcmcia frontend
- NOT TESTED, missing hardware

ehci
- add lots of bus_dmamap_sync() operations, possibly too many
- make sure resources are not allocated in interrupt context
- add support for mapping buffer and mbuf
- done only simple test

uhci
- add lots of bus_dmamap_sync() operations, possibly too many
- make sure resources are not allocated in interrupt context
- add support for mapping buffer and mbuf

To do
- review, test, debug
- rewrite network drivers to utilize usbd_map_buffer_mbuf()
- rewrite uaudio(4) to eliminate memcpy
- "pipe" argument of usbd_setup_*xfer() should eventually be removed

 1.10.32.2  06-Apr-2008  mjf - after some discussion with agc@ i agreed it would be a good idea to move
device_unregister_* to device_deregister_* to be more like the pmf(9)
functions, especially since a lot of the time the function calls are next
to each other.

- add device_register_name() support for dk(4).
 1.10.32.1  05-Apr-2008  mjf - add "file-system DEVFS" and "pseudo-device devfsctl" to conf/std seeing
as these are always needed.

- convert many, many drivers over to the New Devfs World Order. For a
list of device drivers yet to be converted see,
http://www.netbsd.org/~mjf/devfs-todo.html.

- add a new device_unregister_all(device_t) function to remove all device
names associated with a device_t, which saves us having to construct
device names when the driver is detached.

- add a DEV_AUDIO type for devices.

 1.24.4.2  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.
 1.24.4.1  30-Nov-2014  skrll Use C99 types. u_int{8,16,32,64}_t to uint{8,16,32,64}_t.

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)
