 |
|
Hello!
My alpha xp-1000 (Monet) has two usb ports. I wonder if I can make use of them, for memory sticks as an example.
Ok, all respective kernel-settings are done. But what about the hotplug scripts? Installing fails since they are masked in Portage. Do I need them at all? Are there replacements?
Thanks,
Alex |

I have a USB modem in my Alpha, and it works great, but i've never used the hotplug scripts. I can see that their not marked -alpha, which just means they've never been tested, if youd like to try them and let us know (via irc, on irc.freenode.net #gentoo-alpha, or file a bug with platform makred "alpha" on bugs.gentoo.org) if they work we will get them marked alpha in the tree. Just in case you dont know, you can force emerge to install a masked package by giving the full path to the ebuild, like this:
| Code: | # emerge -pv /usr/portage/sys-apps/hotplug/hotplug-20030501-r2.ebuild
# emerge /usr/portage/sys-apps/hotplug/hotplug-20030501-r2.ebuild |
I can see that they are stable on most platforms, so i dont foresee any problems, Thanks!

hotplug requires also masked package usbutils. Forcing emerge of usbutils with
ebuild /usr/portage/sys-apps/usbutils/usbutils-0.11-r1.ebuild merge
fails, because configure fails:
creating cache ./config.cache
checking host system type... Invalid configuration `alphaev6-unknown-linux-gnu': machine `alphaev6-unknown' not recognized
checking target system type... Invalid configuration `alphaev6-unknown-linux-gnu': machine `alphaev6-unknown' not recognized
checking build system type... Invalid configuration `alphaev6-unknown-linux-gnu': machine `alphaev6-unknown' not recognized
Possibly hotplug may do without usbutils. I should try.

| I synced this morning prior to attempting an emerge. Maybe I need another sync method? |

sorry, i meant i literally fixed it a few seconds ago when you reported it. you should emerge sync again to get the new version with the fix.

usbutils compiles! Thanks! I rebuilt the kernel with hotplugging, usb, usbfs, usb-storage, usb-uhci and usb-ohci enabled as modules. However, something doesn't work on booting as expected. Dmesg reports the following usb-related stuff, is there something to be adjusted on the SRM-console?
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
...
usb-ohci.c: found OHCI device with no IRQ assigned. check BIOS settings! (on 9 identical lines)
usb-uhci.c: $Revision: 1.275 $ time 16:39:52 Jul 16 2003
usb-uhci.c: High bandwidth mode enabled
usb-uhci.c: v1.275:USB Universal Host Controller Interface driver
...
usb-ohci.c: found OHCI device with no IRQ assigned. check BIOS settings!
...
usb-uhci.c: $Revision: 1.275 $ time 16:39:52 Jul 16 2003
usb-uhci.c: High bandwidth mode enabled
usb-uhci.c: v1.275:USB Universal Host Controller Interface driver |

I resolved the problem. First I updated the alpha firmware
http://ftp.digital.com/pub/DEC/Alpha/firmware/readmes/v6.5/doc/xp1000_v59_fw_relnote.pdf
Then I enabled usb by entering
set usb_enable on
at the SRM prompt. This feature was not available prior to this update.
Finally I rebuilt the kernel module usb-ohci with IRQ hardcoded to 10. The required modifications to function ohci_pci_probe in file usb-ohci.c are:
/* if (!dev->irq) {
err("found OHCI device with no IRQ assigned. check BIOS settings!");
pci_disable_device (dev);
return -ENODEV;
}
*/
if (!dev->irq) {
dev->irq=10; //hardcoded 20030717
}
Now everything works fine!
