Hi, In vme.c, function vme_master_set(), vme_check_window() is called, where invalid restrictions are applied. In case of address space VME_A16, vme_base + size must not exceed VME_A16_MAX, which is defined in include/linux/vme.h to 0x10000ULL. The second test is never evaluated. As slave windows must not overlap, this means that there can not be more than one window in this address space on any VME bus member, because the only valid base address would be 0x0. The correct test should be the maximum value of a 64-bit unsigned integer plus 1, minus 0xffff; and if checking is already done, maybe some alignment test could help. Other than this, the call to vme_check_window() could also be eliminated. -- Christoph _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
