PCMCIA issues ---> cs: unable to map card memory 0x1000!

[Mathieu Bertrand]

Hi, 
So the "unable to map card memory 0x1000" error is ok.
Now, I try to test both an IDE compact flash card in socket 0 and a 3com LAN
10/100 (3c574_cs) card in socket 1.

Calling cardmgr, I have the following :

# cardmgr -v
cardmgr[3063]: cannot access /lib/modules/2.6.10-rc2: No such file or

Dec 31 17:04:25 cardmgr[3068]: get dev info on socket 1 failed: Resource

So with the ide-cs driver, I have a "ide-cs: GetNextTuple: No more items"
and "get dev info on socket 0 failed: No such device"
With the 3c574_cs driver, I have a "RequestIO: Resource in use" and a "get
dev info on socket 1 failed: Resource temporarily unavailable"

An idea ?


I'm not sure concerning my IO space configuration :
# lspci -v

        I/O window 1: 00003000-00003fff
        16-bit legacy interface ports at 0001

and 

# cat /proc/ioports
e0000000-e7ffffff : MV64340 PCI1 IO MEM
  e0000000-e0003fff : PCI Bus #02
    e0000000-e0000fff : PCI CardBus #03
    e0001000-e0001fff : PCI CardBus #03
    e0002000-e0002fff : PCI CardBus #07
    e0003000-e0003fff : PCI CardBus #07
e8000000-efffffff : MV64340 PCI0 IO MEM

Here is my config in config.opts :

include port 0x0000-0x0fff, port 0x1000-0x1fff
include port 0x2000-0x2fff, port 0x3000-0x3fff
include port 0x4000-0x4fff, port 0x5000-0x5fff
include port 0x6000-0x7fff, port 0x8000-0x9fff
include port 0xa000-0xcfff, port 0xd000-0xffff

So from the MIPS address space, the IO space is located at 0xE0000000 and is
then remapped physically to the PCI address 0.
Not sure it works... 
In fact, can I use an another range than 0-0xffff for the IO space ? It
seems that we can't use IO addresses above 0xffff in config.opts.

Thanks for your help.
Regards.

You need to make more iomem and ioport resources available. Especially some
which are _not_ used as Memory windows or I/O windows on the socket by
default. E.g. on my notebook's yenta sockets there is

Memory window 0: 30400000-307ff000 (prefetchable)
Memory window 1: 30800000-30bff000
I/O window 0: 00004000-000040ff
I/O window 1: 00004400-000044ff

but my /etc/pcmcia/config.opts does not even contain these resources:

include port 0x100-0x4ff, port 0x800-0x8ff, port 0xc00-0xcff
include memory 0xc0000-0xfffff
include memory 0xa0000000-0xa0ffffff, memory 0x60000000-0x60ffffff


Hope that helps,
	Dominik
