https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=255998 Bug ID: 255998 Summary: CAM_DEBUG_LUN=-1 doesn't work as expected Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: luporl@FreeBSD.org According to CAM(4), setting CAM_DEBUG_LUN to -1 should enable debug of all luns. However, it usually results in no CAM debug messages at all. This happens because CAM_LUN_WILDCARD is defined as (~(u_int)0), but the type of the field where CAM_DEBUG_LUN gets stored is lun_id_t, that is an u_int64_t. If CAM_DEBUG_LUN is not defined, or if it is set to 0xffffffff in the kernel config, then it works as expected, selecting all luns. Changing CAM_LUN_WILDCARD to (~(lun_id_t)0) breaks the build, as some drivers use it with 32-bit types, but defining it as (-1) seems to work for me, in some tests with aacraid on PowerPC64. -- You are receiving this mail because: You are the assignee for the bug.
