via 6420 pata/sata controller

via 6420 pata/sata controller

[Zdenek Tlusty]

hello,

I have problem with via 6420 controller under linux (I have mandrake 9.1 with 
kernel 2.4.25 with libata patch version 16).
This controller has two sata and one pata channels. Sata channel works fine 
with libata. My problem is with pata channel. I have pata hard disk on this 
controller. Bios of the controller detected this disk but linux did not.
What is the current status of the driver for this controller?
Thank you for your time.

There are some patches floating around adding support for VT6410
(not VT6420) to generic IDE PCI driver.  This controller may also work
with generic IDE PCI driver (PCI VendorID/ProductID needs to be added
to drivers/ide/pci/generic.h and drivers/ide/pci/generic.c).


http://www.viaarena.com/?PageID=186

"VIA want to make available code and other resources to appropriate open
source developers.  The VIA Open Source Developer's portal currently accepts
requests for IDE and Networking development as well as the CLE266 display
adaptor."

Unfortunately it seems I'm not "appropriate" enough as I didn't get any reply.
:/

BTW Does anybody has contacts in VIA?

Bartlomiej

VT 6420 should be added to via82cxxx.c, since it does the necessary bus 
setup and such.  AFAICS it is programmed just like all the other VIA 
PATA controllers.


> BTW Does anybody has contacts in VIA?

Sure...  I'll check my VT 6420 cards as well.  It should just be another 
PCI id added to via82cxxx.c.

Hello,

I tried to modify via82cxxx.c and .h, but was unsuccessful. Has anyone 
got it to work properly?

If I had to guess, I would try the attached patch.  The via82cxxx.c 
driver is a bit annoying in that, here we do not talk to the ISA bridge 
but to the PCI device 0x4149 itself.

If this doesn't work, I could probably whip together a quick PATA driver 
for libata that works on this hardware.

Re: via 6420 pata/sata controller

[kern.petr]

I downloaded new kernel 2.6.11, applied your's via82cxxx.c patch and 
compiled it (.config was derived "make oldconfig" from 2.6.8 kernel from 
Debian Sarge 3.1).

I created initrd.img with this settings:
/etc/mkinitrd/mkinitrd.conf
--- cut here ---
MODULES=dep
--- cut here ---

/etc/mkinitrd/modules
###
jbd
ext3
ide-core
via82cxxx

I boot PC with this settings:
/etc/modules
###
ide-cd
via82cxxx

Results:
Everything is the same, dmesg, lspci, lspci -n, cat /proc/ioports, lsmod 
as the last email.

Controller still don't working :'(.

PS: I don't add anything into pci_ids.h, I only applied your's 
via82cxxx.c patch:
#define PCI_DEVICE_ID_VIA_6420 0x4149
