Description (Last modified by mentor)

Hi,

i tried to compile r2708-20070915 for 2.6.22.7 kernel on XScale IXP425 box, but the driver wasn't compiling, with error that ioread32be and iowrite32be are undefined. Without finding further information on this topic i managed to build the driver by adding the following lines to ath_hal/ah_os.h: 

#define ioread32be(p)    ({ unsigned int __v = be32_to_cpu(__raw_readl(p)); __v; })
#define iowrite32be(v,a)    __raw_writel(cpu_to_be32((v)),(a))

This way the driver compiled and i was able to load the module in the kernel. However after some time i got the following kernel panic:

  • description changed.

09/28/07 22:32:37 changed by mentor

  • priority changed from critical to major.
  • summary changed from Oops on XScale IXP425 BE to Compilation error: io{read,write}32 not defined (IXP425 - ARM).

Well, that code won't necessarily work, which is why it was changed. Retitling.

09/28/07 22:33:32 changed by mentor

It appears that CONFIG_GENERIC_IOMAP is not turned on for ARM and it does not have its own implementation... hmmm...

09/29/07 17:10:49 changed by david@boreham.org

I am also afflicted by this issue (actually in my case the driver compiles ok and references the symbols io[read|write]32be, but doesn't load at runtime due to unresolved symbols. I'm assuming this is just because I'm building as a module and the build allows unresolved symbols at compile time.

Anyway, I'm willing to expend some time on this. If there's an obvious route to go down (e.g. enabling the generic functions for ARM, writing assembler versions...) then I'm happy to try. Any pointers welcome.

Hi,

@david: Thank you for you patch. With it i was able to connect to the box via wlan. However there still seems to be a problem with the IO-calls. I tried to run tcpdump with the "-nn -i any" parameters and i got this dump:

You need to decode that oops message, as explained on DevDocs/KernelOops. Before pasting the decoded oops here, please refer to WikiFormatting.

fyi, patched as above I've been running two systems for a few days. I suspect that you have found a different bug. I'm pretty sure that r2708 is solid on ixp425.
