Note that data[0].previous_used and data[0].previous_total are not longer written, which is also the case for the NetBSD/OpenBSD case. - Bump PORTREVISION >How-To-Repeat: >Fix: Patch attached with submission follows: ? work Index: Makefile =================================================================== RCS file: /home/pcvs/ports/sysutils/xfce4-cpugraph-plugin/Makefile,v retrieving revision 1.41 diff -u -r1.41 Makefile --- Makefile 26 Oct 2011 20:27:20 -0000 1.41 +++ Makefile 18 Dec 2011 12:59:11 -0000 @@ -7,7 +7,7 @@ PORTNAME= xfce4-cpugraph-plugin PORTVERSION= 1.0.1 -PORTREVISION= 1 +PORTREVISION= 2 CATEGORIES= sysutils xfce MASTER_SITES= ${MASTER_SITE_XFCE} MASTER_SITE_SUBDIR= src/panel-plugins/${PORTNAME}/${PORTVERSION:R} Index: files/patch-panel-plugin__os.c =================================================================== RCS file: files/patch-panel-plugin__os.c diff -N files/patch-panel-plugin__os.c --- /dev/null 1 Jan 1970 00:00:00 -0000 +++ files/patch-panel-plugin__os.c 18 Dec 2011 12:59:11 -0000 @@ -0,0 +1,57 @@ +--- panel-plugin/os.c.orig 2010-11-07 13:58:22.000000000 +0100 ++++ panel-plugin/os.c 2011-12-18 13:52:22.000000000 +0100 +@@ -134,28 +134,41 @@ + #elif defined (__FreeBSD__) + guint detect_cpu_number() + { +- return 1; ++ static gint mib[] = {CTL_HW, HW_NCPU}; ++ gint ncpu; ++ gsize len = sizeof( gint ); ++ if( sysctl( mib, 2, &ncpu, &len, NULL, 0 ) < 0 ) ++ return 0; ++ else ++ return ncpu; + } + + gboolean read_cpu_data( CpuData *data, guint nb_cpu) + { + glong used, total; +- glong cp_time[CPUSTATES]; ++ glong cp_time[CPUSTATES * nb_cpu]; ++ glong *cp_time1; + gsize len = sizeof( cp_time ); ++ gint i; + +- if( sysctlbyname( "kern.cp_time", &cp_time, &len, NULL, 0 ) < 0 ) ++ data[0].load = 0; ++ if( sysctlbyname( "kern.cp_times", &cp_time, &len, NULL, 0 ) < 0 ) + return FALSE; ++ for (i = 1; i <= nb_cpu; i++ ) ++ { ++ cp_time1 = cp_time + CPUSTATES * (i - 1); ++ used = cp_time1[CP_USER] + cp_time1[CP_NICE] + cp_time1[CP_SYS] + cp_time1[CP_INTR]; ++ total = used + cp_time1[CP_IDLE]; ++ if( (total - data[i].previous_total) != 0 ) ++ data[i].load = (CPU_SCALE * (used - data[i].previous_used))/(total - data[i].previous_total); ++ else ++ data[i].load = 0; + +- used = cp_time[CP_USER] + cp_time[CP_NICE] + cp_time[CP_SYS] + cp_time[CP_INTR]; +- total = used + cp_time[CP_IDLE]; +- if( (total - data[0].previous_total) != 0 ) +- data[0].load = (CPU_SCALE * (used - data[0].previous_used))/(total - data[0].previous_total); +- else +- data[0].load = 0; +- +- data[0].previous_used = used; +- data[0].previous_total = total; +- ++ data[i].previous_used = used; ++ data[i].previous_total = total; ++ data[0].load += data[i].load; ++ } ++ data[0].load /= nb_cpu; + return TRUE; + } + >Release-Note: >Audit-Trail: >Unformatted:
