The procfs api does not parse several cards at this time.

Andre,

I swapped out the pdc20268 with a pdc20267, for a total of 2 pdc20267's.
Now all drives will do udma5, no problem. Do you know why the pdc20268's
don't play nice with other ide chipsets (AMD 7411 & pdc20267)?

thanks,

Re: PDC20268 UDMA troubles

[Sean Swallow]

Andre,

Thank you for the reply.

I was wondering if both controllers (PDC20268 and PDC20267) should show up
when I cat /proc/ide/pdc202xx ?

I'm not disabling the BURST_BIT, I think the driver is, but only on the
second card. Thus, I can't get udma5 on all 4 chains.

This is from dmesg:

PDC20267: IDE controller on PCI bus 00 dev 40
PDC20267: chipset revision 2
PDC20267: not 100% native mode: will probe irqs later
PDC20267: (U)DMA Burst Bit ENABLED Primary PCI Mode Secondary PCI Mode.

    ide3: BM-DMA at 0x1088-0x108f, BIOS settings: hdg:DMA, hdh:pio
PDC20268: IDE controller on PCI bus 00 dev 50
PDC20268: chipset revision 2
PDC20268: not 100% native mode: will probe irqs later

    ide5: BM-DMA at 0x10d8-0x10df, BIOS settings: hdk:pio, hdl:pio

Let me know if you need more information.

PDC20268 UDMA troubles

[Sean Swallow]

List,

I have a Tyan Tiger MP 2460 motherboard with a 3c59x ethernet card, a
PDC20267, and a PDC20268; kernel versions 2.4.9 and 2.4.10. I have tried
both PCI and a AGP video cards, with the same results.

I can not get all four chains to do UDMA5 at the same time. This is output
from dmesg (notice the messages from the PDC20268):

I've tried with and without "CONFIG_PDC202XX_BURST".

I tried setting ide4=ata66 and ide5=ata66 but that had no effect.

I also tried replacing the PDC20267 with another PDC20268 and using the
onboard AMD viper with one PDC20268, and still get the same result; 2
chains on the first detected promise card get UDMA, and no other chains
will. =(

Does anyone have any ideas?

thank you,
