+ usbcore.autosuspend=
+ [USB] The autosuspend time delay (in seconds) used

+ help
+ SmartMIPS is a extension of the MIPS32 architecture aimed at
+ increased security at both hardware and software level for
+ smartcards. Enabling this option will allow proper use of the
+ SmartMIPS instructions by Linux applications. However a kernel with
+ this option will not work on a MIPS core without SmartMIPS core. If
+ you don't know you probably don't have SmartMIPS and should say N
+ here.

- * linux/drivers/sbus/char/aurora.c -- Aurora multiport driver
- *
- * Copyright (c) 1999 by Oliver Aldulea (oli at bv dot ro)
- *
- * This code is based on the RISCom/8 multiport serial driver written
- * by Dmitry Gorodchanin (pgmdsg@ibi.com), based on the Linux serial
- * driver, written by Linus Torvalds, Theodore T'so and others.
- * The Aurora multiport programming info was obtained mainly from the
- * Cirrus Logic CD180 documentation (available on the web), and by
- * doing heavy tests on the board. Many thanks to Eddie C. Dost for the
- * help on the sbus interface.

- * along with this program; if not, write to the Free Software
- * Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- * Revision 1.0
- *
- * This is the first public release.
- *
- * Most of the information you need is in the aurora.h file. Please
- * read that file before reading this one.
- *
- * Several parts of the code do not have comments yet.
- *
- * n.b. The board can support 115.2 bit rates, but only on a few
- * ports. The total badwidth of one chip (ports 0-7 or 8-15) is equal
- * to OSC_FREQ div 16. In case of my board, each chip can take 6
- * channels of 115.2 kbaud. This information is not well-tested.
- *
- * Fixed to use tty_get_baud_rate().
- * Theodore Ts'o <tytso@mit.edu>, 2001-Oct-12

- * linux/drivers/sbus/char/aurora.h -- Aurora multiport driver
- *
- * Copyright (c) 1999 by Oliver Aldulea (oli@bv.ro)
- *
- * This code is based on the RISCom/8 multiport serial driver written
- * by Dmitry Gorodchanin (pgmdsg@ibi.com), based on the Linux serial
- * driver, written by Linus Torvalds, Theodore T'so and others.
- * The Aurora multiport programming info was obtained mainly from the
- * Cirrus Logic CD180 documentation (available on the web), and by
- * doing heavy tests on the board. Many thanks to Eddie C. Dost for the
- * help on the sbus interface.

- *
- * Revision 1.0
- *
- * This is the first public release.
- *
- * This version needs a lot of feedback. This is the version that works
- * with _my_ board. My board is model 1600se, revision '@(#)1600se.fth
- * 1.2 3/28/95 1'. The driver might work with your board, but I do not
- * guarantee it. If you have _any_ type of board, I need to know if the
- * driver works or not, I need to know exactly your board parameters
- * (get them with 'cd /proc/openprom/iommu/sbus/sio16/; ls *; cat *')
- * Also, I need your board revision code, which is written on the board.
- * Send me the output of my driver too (it outputs through klogd).
- *
- * If the driver does not work, you can try enabling the debug options
- * to see what's wrong or what should be done.
- *
- * I'm sorry about the alignment of the code. It was written in a
- * 128x48 environment.
- *
- * I must say that I do not like Aurora Technologies' policy. I asked
- * them to help me do this driver faster, but they ended by something
- * like "don't call us, we'll call you", and I never heard anything
- * from them. They told me "knowing the way the board works, I don't
- * doubt you and others on the net will make the driver."
- * The truth about this board is that it has nothing intelligent on it.
- * If you want to say to somebody what kind of board you have, say that
- * it uses Cirrus Logic processors (CD180). The power of the board is
- * in those two chips. The rest of the board is the interface to the
- * sbus and to the peripherals. Still, they did something smart: they
- * reversed DTR and RTS to make on-board automatic hardware flow
- * control usable.
- * Thanks to Aurora Technologies for wasting my time, nerves and money.

* Skeleton Queue Headers
/*
* The UHCI driver uses QHs with Interrupt, Control and Bulk URBs for
* automatic queuing. To make it easy to insert entries into the schedule,
- * we have a skeleton of QHs for each predefined Interrupt latency,
- * low-speed control, full-speed control, bulk, and terminating QH
- * (see explanation for the terminating QH below).
+ * we have a skeleton of QHs for each predefined Interrupt latency.
+ * Asynchronous QHs (low-speed control, full-speed control, and bulk)
+ * go onto the period-1 interrupt list, since they all get accessed on
+ * every frame.
*
- * When we want to add a new QH, we add it to the end of the list for the
- * skeleton QH. For instance, the schedule list can look like this:
+ * When we want to add a new QH, we add it to the list starting from the
+ * appropriate skeleton QH. For instance, the schedule can look like this:
*
* skel int128 QH
* dev 1 interrupt QH
* skel int64 QH
* skel int32 QH
* ...
- * skel int1 QH
- * skel low-speed control QH
- * dev 5 control QH
- * skel full-speed control QH
- * skel bulk QH
+ * skel int1 + async QH
+ * dev 5 low-speed control QH
* dev 1 bulk QH
* dev 2 bulk QH
- * skel terminating QH
*
- * The terminating QH is used for 2 reasons:
- * - To place a terminating TD which is used to workaround a PIIX bug
- * (see Intel errata for explanation), and
- * - To loop back to the full-speed control queue for full-speed bandwidth
- * reclamation.
+ * There is a special terminating QH used to keep full-speed bandwidth
+ * reclamation active when no full-speed control or bulk QHs are linked
+ * into the schedule. It has an inactive TD (to work around a PIIX bug,
+ * see the Intel errata) and it points back to itself.
*
- * There's a special skeleton QH for Isochronous QHs. It never appears
- * on the schedule, and Isochronous TDs go on the schedule before the
+ * There's a special skeleton QH for Isochronous QHs which never appears
+ * on the schedule. Isochronous TDs go on the schedule before the
* the skeleton QHs. The hardware accesses them directly rather than
* through their QH, which is used only for bookkeeping purposes.
* While the UHCI spec doesn't forbid the use of QHs for Isochronous,
* it doesn't use them either. And the spec says that queues never
* advance on an error completion status, which makes them totally
* unsuitable for Isochronous transfers.
+ *
+ * There's also a special skeleton QH used for QHs which are in the process
+ * of unlinking and so may still be in use by the hardware. It too never
