[Yaird-devel] Bug#345374: via82cxxx not correctly detected ?

[Jesus Climent]

Hi.

When upgrading to yaird + linux-image-2.6.{14,15} i suffer from no dma since
yaird does not seem to find my via82cxxx ide controler.

output from initrd's init (relevant part):

/sbin/insmod '/lib/modules/2.6.15-1-686/kernel/drivers/usb/core/usbcore.ko'
/sbin/insmod '/lib/modules/2.6.15-1-686/kernel/drivers/usb/host/uhci-hcd.ko'

Once I recreate the initrc.img file and reboot, with the following entries:

...
/sbin/insmod '/lib/modules/2.6.15-1-686/kernel/drivers/input/evdev.ko'
/sbin/insmod '/lib/modules/2.6.15-1-686/kernel/drivers/ide/ide-core.ko'
/sbin/insmod '/lib/modules/2.6.15-1-686/kernel/drivers/ide/pci/via82cxxx.ko'
/sbin/insmod '/lib/modules/2.6.15-1-686/kernel/drivers/ide/ide-disk.ko'
/sbin/insmod '/lib/modules/2.6.15-1-686/kernel/drivers/ide/ide-generic.ko'
mkbdev '/dev/hda' 'hda'
...

Everything starts working fine (DMA related):

bishop:~# hdparm /dev/hda

/dev/hda:
 multcount    =  0 (off)
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 65535/16/63, sectors = 117231408, start = 0

Cheers,
