Author: ed Date: Wed Dec 14 13:03:01 2016 New Revision: 310055 URL: https://svnweb.freebsd.org/changeset/base/310055 Log: Add a "device_index" label to all sysctls under dev.$driver.$index. This way it becomes possible to graph a property for all instances of a single driver. For example, graphing the number of packets across all USB controllers, the amount of dropped packets on all NICs, etc. Reviewed by: cem Differential Revision: https://reviews.freebsd.org/D8775 Modified: head/sys/kern/subr_bus.c Modified: head/sys/kern/subr_bus.c ============================================================================== --- head/sys/kern/subr_bus.c Wed Dec 14 13:00:27 2016 (r310054) +++ head/sys/kern/subr_bus.c Wed Dec 14 13:03:01 2016 (r310055) @@ -288,10 +288,10 @@ device_sysctl_init(device_t dev) return; devclass_sysctl_init(dc); sysctl_ctx_init(&dev->sysctl_ctx); - dev->sysctl_tree = SYSCTL_ADD_NODE(&dev->sysctl_ctx, + dev->sysctl_tree = SYSCTL_ADD_NODE_WITH_LABEL(&dev->sysctl_ctx, SYSCTL_CHILDREN(dc->sysctl_tree), OID_AUTO, dev->nameunit + strlen(dc->name), - CTLFLAG_RD, NULL, ""); + CTLFLAG_RD, NULL, "", "device_index"); SYSCTL_ADD_PROC(&dev->sysctl_ctx, SYSCTL_CHILDREN(dev->sysctl_tree), OID_AUTO, "%desc", CTLTYPE_STRING | CTLFLAG_RD, dev, DEVICE_SYSCTL_DESC, device_sysctl_handler, "A",
