VIA VT82C416MV support

VIA VT82C416MV support

[Piotrek Kaczmarek]

Hi,
I use 2.4.10-pre1-xfs series kernel (cvs checkout 2001-08-28)
on a P133 based on a motherboard (don't remeber the manufacturer) 
with some VIA IDE controller, which seems to be
PCI_IDE: unknown IDE controller on PCI bus 00 device 08, VID=1106, DID=1571
for IDE driver....
VIA_82CXXX suport is compiled in kernel

Unfortunately i was unable to use UDMA33 mode with my
FUJITSU MPF3204AT, ATA DISK drive (20496MB w/512KiB Cache)

Here's my lspci -vvv output
00:01.0 IDE interface: VIA Technologies, Inc. VT82C416MV (rev 04) (prog-if 8a [Master SecP PriP])
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-

        Latency: 32
        Region 4: I/O ports at 6000 [size=16]
Is that controller supported in 2.4 kernels ? or maybe i am missing something?

I'd be appreciated for any response

Wow, this must be a very ancient hardware! If you send me lspci -vvxxx,
I'll take a look and perhaps we could make it work.

This is probably a bad entry in the database. The IDE/ISA chip
on your board is probably vt82c576m.

This (a8 20 a8 20 ff 00 ff ff) suggests that the chip could work with
the normal vt82cxxx.c IDE driver. It refuses to do that now, though.

Could you send me the whole lspci -vvxxx, including namely the ISA
bridge? With that knowledge I should be able to make a patch for you
that'll enable your chip in vt82cxxx.c
