SubjectRe: [PATCH] pcmcia event thread. (fwd)

I have an i82092AA evaluation board:

00:06.0 PCMCIA bridge: Intel Corporation 82092AA_0 (rev 02)
Flags: slow devsel, IRQ 27
I/O ports at 8400 [size=4]

I have three problems:

1. I have to specify the i365_base parameter when loading i82365,o

2. Even when I specify cs_irq=27, it resorts to polling:

Intel PCIC probe:
Intel i82365sl DF ISA-to-PCMCIA at port 0x8400 ofs 0x00, 2 sockets
host opts [0]: none
host opts [1]: none
ISA irqs (default) = none! polling interval = 1000 ms
Intel i82365sl DF ISA-to-PCMCIA at port 0x8400 ofs 0x80, 2 sockets
host opts [2]: none
host opts [3]: none
ISA irqs (default) = none! polling interval = 1000 ms

3. Note that it finds no IRQs available for the cards' IREQ to use. This is
on an Alpha SX164.

I'll fix it over the weekend - basically it just looks like a little too
much was stripped out of i82365.c when we started handling CardBus bridges
elsewhere. We ought to still handle PCI->PCMCIA bridges which aren't
CardBus-capable.


As a separate issue, the IDE on the same chip appears to be confusing the
kernel. I seem to end up with the generic IDE driver driving the on-board
CY82C693, which means I can't do DMA. That may be SRM's fault, though.


00:06.1 IDE interface: Intel Corporation 82092AA_1 (rev 02) (prog-if 00 [])
Flags: slow devsel, IRQ 31
I/O ports at 1090 [size=8]
I/O ports at 1098
I/O ports at 10a0 [size=8]
I/O ports at 10a8 [size=8]

00:08.1 IDE interface: Contaq Microsystems 82c693 (prog-if 80 [Master])
Flags: bus master, medium devsel, latency 0
I/O ports at 01f0 [size=8]
I/O ports at 03f4
I/O ports at 1080 [size=16]

ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
PCI_IDE: unknown IDE controller on PCI bus 00 device 31, VID=8086, DID=1222
PCI_IDE: chipset revision 2
PCI_IDE: not 100% native mode: will probe irqs later
CY82C693: IDE controller on PCI bus 00 dev 41

CY82C693: neither IDE port enabled (BIOS)
