Hi I need to build a driver on the kernel version 2.4.22 on Mips architecture ( I am using an AMD board). When I try to insmod the driver it gives unresolved symbols for "__up, __down_trylock & __down_interruptible". I checked in the semaphore.c file under kernel/arch/mips. The above symbols are neither defined nor exported while they are done for the semaphore files under other arch like sparc, sh, alpha etc. If I try to use the functions from the latest CVS files in the mips-org site it gives other compilation errors. Please can you tell me how do I go about this problem. Have the above functions been obsoleted? Is there any patch available for them? Or is there any doc explaining this? I am using Kernel version 2.4.22. Can anybody help me out with this please. Rgds Priya
