Potential problem with USB_THREAD_SUSPEND()?
Hi,
USB_THREAD_SUSPEND(p) is defined as {kproc|kthread}_suspend(p, 0). This means
that it will wait until the corresponding thread recognizes its suspend request
and suspends itself. It seems that {kproc|kthread}_suspend_check() will be
used nowhere in the USB system. Thus the USB_THREAD_SUSPEND() will block
forever in most cases? It is only used in usb_proc_drain() during cold boot.
Have a nice day!

Re: CPU Cache and busdma usage in USB
Hi! The general approach for systems with no hardware cache coherence protocol should be: Memory to device DMA transfer of a buffer: 1. write all modified cache lines of the buffer back to memory (cache flush for buffer) 2. start DMA transfer Device to memory DMA transfer of a buffer: 1. invalidate the cache of the buffer, here you have to make sure that this buffer does not share a cache line with other buffers (!) 2. start DMA transfer 3. all accesses to the buffer via the cache must wait until the DMA has finished CU -- Sebastian Huber, Embedded Brains GmbH Address : Obere Lagerstr. 30, D-82178 Puchheim, Germany Phone : +49 89 18 90 80 79-6 Fax : +49 89 18 90 80 79-9 E-Mail : sebastian.hu...@embedded-brains.de PGP : Public key available on request Diese Nachricht ist keine geschäftliche Mitteilung im Sinne des EHUG. ___ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"

How fast is the OHCI driver?
Hi, I work with an ARM9 based system on a LPC3250 evaluation board from Phytec. It has an integrated OHCI USB controller from NXP. The vendor provides a Linux system for this board and with this system I can read with 1MByte/s from an USB stick (I can also read with 23MByte/s from this stick on another system with an EHCI controller). If I use the FreeBSD USB-stack (trunk revision 200101), then I can only achieve a read performance of 70kByte/s. Comparing the activity on the USB data lines with an oscilloscope of the two systems shows that on the Linux system the line is continuously busy while on the FreeBSD based system there are huge gaps of inactivity. Both systems operate with 12MHz. The FreeBSD based system is 65% of the time in the idle task, so it seems that it waits a lot for something. Has someone values from other FreeBSD based systems with an OHCI controller? Have a nice day!

Thank you for your reference values. Actually my test setup on the FreeBSD
based system was bad. I now have the following values:
TSZ: Size of one transfer block in bytes
TIME: Time to transfer 1024 blocks in seconds
RATE: Bytes transfered per second
TSZ TIME RATE
512 6.15 85250
1024 7.17 146244
2048 8.20 255750
4096 10.24 409600
8192 13.38 626951
16384 21.50 780335
32768 36.92 908841
65536 67.92 988057
131072 131.39 1021521
262144 259.00 1036430
524288 514.16 1044170
1048576 964.04 1048532
So it looks very good if you use the right transfer size.
Best regards,
Sebastian Huber

You cannot disable the USB debug support completely (USB_DEBUG define) due to
an intermix of #if and #ifdef handling. The header file usb_freebsd.h defines
USB_DEBUG if it is undefined. So the USB_DEBUG pre-processor symbol is always
defined. Thus you cannot use #ifdef and #ifndef to test if debugging support
should be enabled or disabled.

Hi,
Thank you for your optimisation patch:
https://svnweb.freebsd.org/changeset/base/290195
Thanks.
How does the DWC OTG driver from FreeBSD work with your setup?
After an update of the USB stack from 9.3 to current it worked out of
the box. Thanks a lot for your great USB stack!
It seems that this driver doesn't support DMA. I see a quite high CPU
utilization in this area:
static void
dwc_otg_interrupt_poll_locked(struct dwc_otg_softc *sc)
{
[...]
if (sc->sc_last_rx_status != 0) {

dwc_otg: Problem with directly connected full/low speed devices
Hello,
I use an Altera Cyclone V development kit which the dwc_otg driver from
FreeBSD. The device enumeration of full/low speed devices directly
connected to the root hub fails since split transactions are used. If I
connect them via a hub it works fine. I used the following hack to get
them working with a direct connection:
diff --git a/sys/dev/usb/controller/dwc_otg.c
b/sys/dev/usb/controller/dwc_otg.c

I am not sure how to fix this properly. Is this a specific problem with
the Altera Cyclone V board or is this problem also present on other
boards e.g. RPI2?

USB Host Driver for Atmel USB High-Speed Interface (USBHS)?
Hello, there are several Atmel USB controllers supported by FreeBSD. However, support for the Atmel USB High-Speed Interface (USBHS) module seems to be missing. This module can be found for example on the ATSAMV71Q21: http://www.atmel.com/devices/ATSAMV71Q21.aspx Does someone know if this module is supported (maybe out of tree) or is someone working on a driver already? If not, then in case someone is able to develop a FreeBSD driver for this module, then please contact me to potentially do this on a contract basis. -- Sebastian Huber, embedded brains GmbH Address : Dornierstr. 4, D-82178 Puchheim, Germany Phone : +49 89 189 47 41-16 Fax : +49 89 189 47 41-09 E-Mail : sebastian.hu...@embedded-brains.de PGP : Public key available on request.

Hi, Can you check if you have a match with avr32dci.c in sys/dev/usb/controller ? The register interface looks similar, but this is a device only driver? At least I don't find defines for the host registers. I need the host mode. -- Sebastian Huber, embedded brains GmbH Address : Dornierstr. 4, D-82178 Puchheim, Germany Phone : +49 89 189 47 41-16 Fax : +49 89 189 47 41-09 E-Mail : sebastian.hu...@embedded-brains.de PGP : Public key available on request.
