mpc / linux kernel - user space

Hello, I tried to make use of wake_up_interruptible(wq) in my module as following (I just wanted to test if I'm using it correctly): If I'm doing insmod, the module blocks in the wake_up_interruptible call. Does somebody know why? Maybe because there is no process sleeping? How do I check this? D

2003-12-01 Thread [EMAIL PROTECTED]
Hi, I could get PCI working on MBX860 with few changes to qspan_pci.c file (see the patch below) on linux-2.4.21. Do note that there are many copies of this file in different directories (arch/ppc/kernel, arch/ppc/syslib, arch/ppc/boot/simple). The one in boot/simple seems to be the older one (qsp

All, A quick search on this mailing list will point to a replay by Wolfgang Denk to exactly the same question. Try http://lists.linuxppc.org/linuxppc-embedded/200107/msg00154.html The subject is Interfacing user application and interrupt. I have just done exactly this using Wolfgang's reply to

Peripherals Memory Mapping

2003-12-01 Thread Kevin A. Sapp
Hello, Maybe this is a simple question, but I have searched the code and played around with no luck. This is for an 8260 FADS board, later to be used on custom H/W. How and where do I add peripherals memory to the memory map? I have tried adding it in the ads_map_io function but when I try to
