RE: mips kernel 2.6.16rc1 + IET 0.4.13 - /dev/ietctl - ioctl unknown command

[Shanthi Kiran Pendyala (skiranp)]

I have seen such error messages when userspace app is built in 32bit
mode
And kernel is built in 64 bit mode. Does this apply to your setup ?

The way to fix this is to register a ioctl32 conversion routine in
The driver. Google is your friend..

Thx

[Ming Zhang]

thanks. i guess this is the reason.

@Frederic, could you confirm this? also if you compile u user space as
64bit, it should be ok then.

Re: [Iscsitarget-devel] RE: mips kernel 2.6.16rc1 + IET 0.4.13 - /dev/ietctl - ioctl unknown command

[Frederic Temporelli]

Hi,

Sorry, I'm not able to build 64 bits user space binaries (Debian distro, 
where all binaries are 32 bits... ld is reporting errors when I try to 
link using o64 and n64 ABIs, seems that only the kernel can be 64 bits).

But don't care, on my side it was just to do a test to IET.
I'll try do test it at work on IA64...
