VIA 4.2x driver for 2.2 kernels
PATCH 1/1 VIA 4.2x driver for 2.2 kernels
Hi Andre!
You wanted my VIA driver for 2.2. Here is a patch that brings the very latest 4.2 driver to the 2.2 kernel. The patch is against the 2.2.19-pre13 kernel plus yours 1221 ide patch.
Enjoy!

Hi,
This drivers breaks with my HP 8110 CD-R drive. It's sitting on primary slave of a Via 686B controler. When I try to do a hdparm -d1 -u1 -k1 /dev/hdb, the kernel locks up hard. Not even an oops. Reverting to the old driver works fine.
Uniform Multi-Platform E-IDE driver Revision: 6.30
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xxVP_IDE: IDE controller on PCI bus 00 dev 39VP_IDE: chipset revision 6VP_IDE: not 100%% native mode: will probe irqs laterVP_IDE: VIA vt82c686b (rev 40) IDE UDMA100 controller on pci00:07.1
ide0: BM-DMA at 0xc000-0xc007, BIOS settings: hda:pio,
hdb:pio
ide1: BM-DMA at 0xc008-0xc00f, BIOS settings: hdc:pio,hdd:pio
HPT370: IDE controller on PCI bus 00 dev 70

hdb: Hewlett-Packard CD-Writer Plus 8100, ATAPI CDROM driveVP_IDE: Calibrating PCI clock ... 34.91 MHz
hde: Maxtor 92720U8, ATA DISK drive

ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide2 at 0xdc00-0xdc07,0xe002 on irq 10
ide3 at 0xe400-0xe407,0xe802 on irq 10
hde: Maxtor 92720U8, 25965MB w/2048kB Cache, CHS=52755/16/63, UDMA(66)
hdg: Maxtor 96147U8, 58623MB w/2048kB Cache, CHS=119108/16/63, UDMA(66)
The one thing I see here which looks odd is the PCI clock timing at 34.91 MHZ. The CPU is not overclocked so the PCI clock should be 33MHZ but that's probably not related.
Regards,
Shane

Don't do that. Use the kernel option to enable DMA instead.
Hmm, I'll have to look into this anyway - many users seem to do that and it isn't as harmless as it looks (it worked by pure luck with the previous version).

Ok, can I still use -u1 -k1 -c1 on the drives or is it even necessary anymore. Is the deprecation of -d1 VIA IDE specific or does it apply to the entire subsystem.

If you enable automatic DMA in the kernel config, it isn't necessary at all. The VIA driver sets up everything.

Well, in my opinion it was always a potentially dangerous option and so it remains. I'll update the VIA driver to make sure its not dangerous at least with it anymore.
Scenario:
1) AutoDMA not enabled
2) VIA sets PIO mode on boot
3) User enables DMA -> IDE driver starts using dma
4) But VIA is still set to PIO mode
I'll have to make the VIA driver check when IDE dma is enabled, test whether the chipset was already programmed for it and program the chipset for it if needed.

You mean using hdparm can cause problems? Could you provide more details on the problems that could arise? I'm completely ignorant on the subject...

Ok. Please disregard my last message (this one contains exactly what I was looking for).

Why does this happen?
And what about the other options to hdparm (-u1 -k1 -c1)? Are they potentially dangerous also?

Well, I checked today and my fears were *not* confirmed. Actually the VIA driver will set up the chipset for UDMA even when UDMA won't be later used, so it's all OK.

Hi,
I have investigated this problem further. The hdparm triggers the error but is not the cause. hdparm accesses /dev/hdb which is my cd-r drive. This triggers the loading of the cdrom and ide-cd modules. Manually loading cdrom succeeds, after which, manually loading ide-cd crashes the system. No need to even open() the device. This works fine with the VIA driver from 2.2.19pre14+ide-2.2.18-1221.
Regards,
Shane
