Dear list, I just (finally) added a second cpu to my Gigabyte 586DX board, upgraded from 2.2-Stable to 3.0-Current, compiled an SMP kernel with the default options, and It Just Worked. GREAT! I have a few questions. BTW, my cvs source tree is up to date till 16-nov. Although I'm compiling something right now, top shows that the machine is almost idle. (It certainly isn't.) For example: CPU states: 4.7% user, 0.0% nice, 20.3% system, 0.8% interrupt, 74.2% idle Mem: 3892K Active, 28M Inact, 15M Wired, 12M Cache, 7595K Buf, 2540K Free Swap: 128M Total, 5728K Used, 122M Free, 4% Inuse PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAND 12309 root 10 0 1240K 644K wait 0 0:02 0.31% 0.31% make 13234 root 73 0 1972K 1872K CPU0 0 0:00 3.12% 0.15% cc1 13235 root -6 0 504K 656K piperd 0 0:00 1.56% 0.08% as 13232 root 10 0 220K 476K wait 0 0:00 0.78% 0.04% cc 10434 benst 28 0 832K 572K CPU1 1 0:02 0.04% 0.04% top I tried to compile a kernel (GENERIC to be exact) with make -j4, but it failed: make -j4 --- symbols.exclude --- --- symbols.sort --- --- if_vx.o --- --- cd9660_bmap.o --- --- symbols.exclude --- echo "gcc2_compiled." >symbols.exclude echo "___gnu_compiled_c" >>symbols.exclude --- symbols.sort --- grep -v '^#' ../../i386/i386/symbols.raw | sed 's/^ //' | sort -u > symbols.sort --- if_vx.o --- cc -c -O -pipe -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wuninitialized -nostdinc -I- -I. -I../.. -I../../../include -DFAILSAFE -DCOMPAT_43 -DMSDOSFS -DNFS -DFFS -DINET -DKERNEL -include opt_global.h ../../dev/vx/if_vx.c --- cd9660_lookup.o --- --- cd9660_bmap.o --- cc -c -O -pipe -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wuninitialized -nostdinc -I- -I. -I../.. -I../../../include -DFAILSAFE -DCOMPAT_43 -DMSDOSFS -DNFS -DFFS -DINET -DKERNEL -include opt_global.h ../../isofs/cd9660/cd9660_bmap.c --- cd9660_node.o --- --- cd9660_bmap.o --- In file included from ../../isofs/cd9660/cd9660_bmap.c:43: ../../sys/vnode.h:429: vnode_if.h: No such file or directory --- cd9660_lookup.o --- cc -c -O -pipe -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wuninitialized -nostdinc -I- -I. -I../.. -I../../../include -DFAILSAFE -DCOMPAT_43 -DMSDOSFS -DNFS -DFFS -DINET -DKERNEL -include opt_global.h ../../isofs/cd9660/cd9660_lookup.c --- cd9660_node.o --- cc -c -O -pipe -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wuninitialized -nostdinc -I- -I. -I../.. -I../../../include -DFAILSAFE -DCOMPAT_43 -DMSDOSFS -DNFS -DFFS -DINET -DKERNEL -include opt_global.h ../../isofs/cd9660/cd9660_node.c --- cd9660_bmap.o --- In file included from ../../isofs/cd9660/cd9660_bmap.c:43: ../../sys/vnode.h:450: warning: `struct vop_lease_args' declared inside parameter list ../../sys/vnode.h:450: warning: its scope is only this definition or declaration, ../../sys/vnode.h:450: warning: which is probably not what you want. ../../sys/vnode.h:464: warning: `struct vop_lease_args' declared inside parameter list ../../sys/vnode.h:489: warning: `struct vop_lookup_args' declared inside parameter list ../../sys/vnode.h:494: warning: `struct vop_islocked_args' declared inside parameter list ../../sys/vnode.h:495: warning: `struct vop_lock_args' declared inside parameter list ../../sys/vnode.h:496: warning: `struct vop_unlock_args' declared inside parameter list ../../sys/vnode.h:497: warning: `struct vop_islocked_args' declared inside parameter list ../../sys/vnode.h:498: warning: `struct vop_lock_args' declared inside parameter list ../../sys/vnode.h:499: warning: `struct vop_poll_args' declared inside parameter list ../../sys/vnode.h:500: warning: `struct vop_unlock_args' declared inside parameter list ../../sys/vnode.h:501: warning: `struct vop_pathconf_args' declared inside parameter list ../../sys/vnode.h:502: warning: `struct vop_revoke_args' declared inside parameter list ../../sys/vnode.h:503: warning: `struct vop_lock_args' declared inside parameter list --- cd9660_lookup.o --- ... etc Even a make -j1 has this problem. A make without any -j option works fine. Did I miss something? Any ideas? Thanks, Ben
