About peak_pci PATCH v6.1

Hi Oliver,

Thanks for your tests on usb adapters, I'll have a look to these diags.
Did you also plan to test the pciec card under heavy traffic? I would like to close that problem first...

Regards,

Stéphane

Unfortunately i didn't find the time @work, where i have the PCIeC slot to test. Will do tomorrow.

Hello Stephane,

you can add to all these drivers

- peak_pci v6.1 (http://marc.info/?l=linux-can&m=132973636320107&w=2)
- peak_usb v6 (http://marc.info/?l=linux-can&m=132998590401560&w=2)
- peak_pcmcia v4.1 (http://marc.info/?l=linux-pcmcia&m=132938721324159&w=2)

my

Very impressive! Whatever i tried - i didn't run into any problem with plugging / unplugging all of these interfaces (with & without traffic load).

Testbed was:

peak_pci 0000:0e:00.0: can0 at reg_base=0xf827e000 cfg_base=0xf814e000 irq=19 peak_pci 0000:0e:00.0: can1 at reg_base=0xf827e400 cfg_base=0xf814e000 irq=19 peak_pcmcia 0.0: PEAK-System pcmcia card PC_CAN_CARD fw 1.5
peak_pcmcia 0.0: can2 on channel 0 at 0x00012100 irq 19
peak_pcmcia 0.0: can3 on channel 1 at 0x00012120 irq 19
peak_usb 2-2:1.0: PEAK-System PCAN-USB Pro hwrev 0 serial FFFFFFFF.00000001 (2 channels) peak_usb 2-2:1.0: can4: attached to PCAN-USB Pro channel 0 (device 1) peak_usb 2-2:1.0: can5: attached to PCAN-USB Pro channel 1 (device 0) peak_usb 5-1:1.0: PEAK-System PCAN-USB adapter hwrev 28 serial FFFFFFFF (1 channel) peak_usb 5-1:1.0: can6: attached to PCAN-USB channel 0 (device 46)

can0 - can2 - can4 - can6 - PEAK MicroMod (for 100% busload) can1 - can3 - can5

Just two nitpicks:

When having traffic the LEDs from the PCIeC are flashing faster than the PCMCIA LEDs. With no traffic and interface is up, they are flashing with the same frequency.

The other one:

usb 2-2: new high-speed USB device number 4 using ehci_hcd
usb 2-2: config 1 interface 0 altsetting 0 bulk endpoint 0x83 has invalid maxpacket 64 usb 2-2: config 1 interface 1 altsetting 0 bulk endpoint 0x86 has invalid maxpacket 64 peak_usb 2-2:1.0: PEAK-System PCAN-USB Pro hwrev 0 serial FFFFFFFF.00000001 (2 channels) peak_usb 2-2:1.0: can4: attached to PCAN-USB Pro channel 0 (device 1) peak_usb 2-2:1.0: can5: attached to PCAN-USB Pro channel 1 (device 0)
usbcore: registered new interface driver peak_usb

Do you have any idea what

"altsetting 0 bulk endpoint 0x83 has invalid maxpacket 64"

means?

Is this something that's caused by your driver or it is caused by the hardware configuration of the USBpro adapter? I assume it's the latter.

Oliver

Hi Oliver,

Thanks for all of your precious time.

... I should check whether the two boards use the same chip to control the LEDs... But I think that the word "nitpicks" was especially invented for that particular issue ;-)

Yes you're right. These msgs are printed by the usb-core, before the _probe() function of the driver is called. It is something I will send back to our hw team...

Best regards,

Stéphane
