Basically the steps are: - find out which ioctl it is. - check its arguments. if the arguments are 64bit clean (see http://www.firstfloor.org/~andi/writing-ioctl32 for a definition) you just add it as COMPATIBLE_IOCTL to arch/x86_64/ia32/ia32_ioctl.c If not you have to write a conversion handler, also following the tutorial in writing-ioctl32. > > 2. gdb still seems broken. gdb ./sleep [where ./sleep is simply main() calling > nanosleep(), but linked with -lpthread] hangs or loops and takes forever > to respond to ^C. It works with the SuSE 32bit gdb/userland. I think RedHat has a different libpthread. I don't have a RedHat userland, so someone else will have to debug it. > > 3. bootsect.S still needs a patch to prevent 'bzdisk' kernels from > disabling the FDC I put your previous patch already into CVS, but that was after the last Marcelo sync. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
