kernel patch to make device ID available in sysfs (2.29 KB, patch)

Description David Woodhouse 2005-12-21 19:11:19 EST
printconf_conf.py contains this gem:

        magic_perl = "perl -e 'ioctl(STDIN,0x84005001,$result);"
        magic_perl += "print $result' 2>/dev/null <"
        foo = os.popen (magic_perl + dev)

That magic number is supposed to be IOCNR_GET_DEVICE_ID(0x400), which is 
_IOR(_IOC_READ, 'P', 1, 0x400), which in turn comes out at 0x44005001 on my
platform du jour. And thus autoprobe of USB printers is failing.

Would this help?

The kernel patch is now in the upstream kernel and also now building in the FC5
kernel-2.6.15-1.1826.2.6.FC5. Please use it :)
Comment 3 David Woodhouse 2006-03-16 11:54:14 EST
Did this get fixed for FC5? Do we use the information in sysfs instead of the
broken ioctl code now?
Comment 4 Tim Waugh 2006-03-16 12:52:54 EST
Busy fixing the larger problem of 'printconf is generally rubbish'.  I expect
we'll use the sysfs code in hal.
Comment 5 Tim Waugh 2007-01-15 07:18:25 EST
Reassigning to hal so that it can make use of this new sysfs interface.
