Hello, I have several brief questions on issues I'm slightly stuck on: 1. For buildworld, my /etc/src.conf uses default CROSS_COMPILER, CLANG_BOOTSTRAP, CLANG_FULL for amd64, but I would like clang to xbuild only for target i386 as I do not need the others (like Target/arm). Is there a knob for this?
2. Is there a way to read a list of modules inside an unloaded kernel? Sort of "kldstat -v" for a non-loaded kernel? Reading the kernel manifest (INCLUDE_CONFIG_FILE setting) is not what I need. 3. Under one scenario, I'm getting a kernel panic but I cannot dump because busybox states "no dumpdev specified" which means rc.conf (where I have dumpdev set) has not been read yet. How can I pass dumpdev wile in busybox command line so that ">dump" does its job? 4. Getting several of these lock order reversals. Kernel is drm-next but Generic from Head gives the same messages. Not urgent, just FYI. lock order reversal: 1st 0xfffff80064915040 filedesc structure (filedesc structure) @ /asp/git/srcdrm/sys/kern/kern_descrip.c:1234 2nd 0xfffff8002e9f0d50 ufs (ufs) @ /asp/git/srcdrm/sys/kern/vfs_subr.c:5022 stack backtrace: #0 0xffffffff804d3180 at witness_debugger+0x70 #1 0xffffffff804d3073 at witness_checkorder+0xe23 #2 0xffffffff8044aa35 at __lockmgr_args+0x875 #3 0xffffffff814d09e5 at ffs_lock+0xa5 #4 0xffffffff80717840 at VOP_LOCK1_APV+0xe0 #5 0xffffffff8054847a at _vn_lock+0x6a #6 0xffffffff8042c9c8 at knlist_remove_kq+0x88 #7 0xffffffff8053f358 at filt_vfsdetach+0x28 #8 0xffffffff8042d4f1 at knote_fdclose+0x171 #9 0xffffffff804206b5 at closefp+0x65 #10 0xffffffff806afe9a at amd64_syscall+0x57a #11 0xffffffff80692dcb at Xfast_syscall+0xfb lock order reversal: 1st 0xfffff80064915040 filedesc structure (filedesc structure) @ /asp/git/srcdrm/sys/kern/kern_descrip.c:1234 2nd 0xfffff8004b4d3d50 zfs (zfs) @ /asp/git/srcdrm/sys/kern/vfs_subr.c:5022 stack backtrace: #0 0xffffffff804d3180 at witness_debugger+0x70 #1 0xffffffff804d3073 at witness_checkorder+0xe23 #2 0xffffffff8044a0fe at lockmgr_lock_fast_path+0x1ce #3 0xffffffff80717840 at VOP_LOCK1_APV+0xe0 #4 0xffffffff8054847a at _vn_lock+0x6a #5 0xffffffff8042c9c8 at knlist_remove_kq+0x88 #6 0xffffffff8053f358 at filt_vfsdetach+0x28 #7 0xffffffff8042d4f1 at knote_fdclose+0x171 #8 0xffffffff804206b5 at closefp+0x65 #9 0xffffffff806afe9a at amd64_syscall+0x57a #10 0xffffffff80692dcb at Xfast_syscall+0xfb lock order reversal: 1st 0xfffff801aec715f0 syncer (syncer) @ /asp/git/srcdrm/sys/kern/vfs_subr.c:2152 2nd 0xfffff8004bc3e068 zfs (zfs) @ /asp/git/srcdrm/sys/kern/vfs_subr.c:2602 stack backtrace: #0 0xffffffff804d3180 at witness_debugger+0x70 #1 0xffffffff804d3073 at witness_checkorder+0xe23 #2 0xffffffff8044a0fe at lockmgr_lock_fast_path+0x1ce #3 0xffffffff80717840 at VOP_LOCK1_APV+0xe0 #4 0xffffffff8054847a at _vn_lock+0x6a #5 0xffffffff80538892 at vget+0x82 #6 0xffffffff8053a936 at vfs_msync+0xa6 #7 0xffffffff8053ef96 at sync_fsync+0xc6 #8 0xffffffff80716890 at VOP_FSYNC_APV+0xe0 #9 0xffffffff8053d2fc at sched_sync+0x36c #10 0xffffffff80436f44 at fork_exit+0x84 #11 0xffffffff8069301e at fork_trampoline+0xe lock order reversal: 1st 0xfffff80039590d50 zfs (zfs) @ /asp/git/srcdrm/sys/kern/vfs_mount.c:855 2nd 0xfffff8001a4489a0 devfs (devfs) @ /asp/git/srcdrm/sys/kern/vfs_subr.c:2602 stack backtrace: #0 0xffffffff804d3180 at witness_debugger+0x70 #1 0xffffffff804d3073 at witness_checkorder+0xe23 #2 0xffffffff8044a0fe at lo ckmgr_lock_fast_path+0x1ce #3 0xffffffff80717840 at VOP_LOCK1_APV+0xe0 #4 0xffffffff8054847a at _vn_lock+0x6a #5 0xffffffff80538892 at vget+0x82 #6 0xffffffff80395b2d at devfs_allocv+0xcd #7 0xffffffff80395643 at devfs_root+0x43 #8 0xffffffff8052f66f at vfs_donmount+0x118f #9 0xffffffff8052e4b2 at sys_nmount+0x72 #10 0xffffffff806afe9a at amd64_syscall+0x57a #11 0xffffffff80692dcb at Xfast_syscall+0xfb _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
