* - Make SCHED_STATS more generic by adding a wrapper to create theJeff Roberson2008-04-171-0/+1
| | | | | | | | | | | | | | | | | | | | | variables and sysctl nodes. - In reset walk the children of kern_sched_stats and reset the counters via the oid_arg1 pointer. This allows us to add arbitrary counters to the tree and still reset them properly. - Define a set of switch types to be passed with flags to mi_switch(). These types are named SWT_*. These types correspond to SCHED_STATS counters and are automatically handled in this way. - Make the new SWT_ types more specific than the older switch stats. There are now stats for idle switches, remote idle wakeups, remote preemption ithreads idling, etc. - Add switch statistics for ULE's pickcpu algorithm. These stats include how much migration there is, how often affinity was successful, how often threads were migrated to the local cpu on wakeup, etc. Sponsored by: Nokia Notes: svn path=/head/; revision=178272

* Add very basic support for the kernel to export a list of features. EachJohn Baldwin2007-12-311-0/+8
| | | | | | | | | | | | | | | feature is represented by a node in the new 'kern.features' sysctl node. A feature is present if the corresponding node is present and evaluates to true. A FEATURE() wrapper macro is added which takes the sysctl node name and a description of the feature as the sole arguments and creates a read-only sysctl node with a value of 1.

* Add another new sysctl in support of the forthcoming procstat(1) toRobert Watson2007-12-021-0/+1
| | | | | | | | | | | | | | | | | support its -k argument: kern.proc.kstack - dump the kernel stack of a process, if debugging is permitted. This sysctl is present if either "options DDB" or "options STACK" is compiled into the kernel. Having support for tracing the kernel stacks of processes from user space makes it much easier to debug (or understand) specific wmesg's while avoiding the need to enter DDB in order to determine the path by which a process came to be blocked on a particular wait channel or lock.

* Add two new sysctls in support of the forthcoming procstat(1) to supportRobert Watson2007-12-021-0/+3
| | | | | | | | | | | | | | | | | | | its -f and -v arguments: kern.proc.filedesc - dump file descriptor information for a process, if debugging is permitted, including socket addresses, open flags, file offsets, file paths, etc. kern.proc.vmmap - dump virtual memory mapping information for a process, if debugging is permitted, including layout and information on underlying objects, such as the type of object and path. These provide a superset of the information historically available through the now-deprecated procfs(4), and are intended to be exported in an ABI-robust form. Notes: svn path=/head/; revision=174167

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit includes the following core components: * sample configuration file for sensorsd * rc(8) script and glue code for sensorsd(8) * sysctl(3) doc fixes for CTL_HW tree * sysctl(3) documentation for hardware sensors * sysctl(8) documentation for hardware sensors * support for the sensor structure for sysctl(8) * rc.conf(5) documentation for starting sensorsd(8) * sensor_attach(9) et al documentation * /sys/kern/kern_sensors.c o sensor_attach(9) API for drivers to register ksensors o sensor_task_register(9) API for the update task o sysctl(3) glue code o hw.sensors shadow tree for sysctl(8) internal magic * <sys/sensors.h> * HW_SENSORS definition for <sys/sysctl.h> * sensors display for systat(1), including documentation * sensorsd(8) and all applicable documentation The userland part of the framework is entirely source-code compatible with OpenBSD 4.1, 4.2 and -current as of today. All sensor readings can be viewed with `sysctl hw.sensors`, monitored in semi-realtime with `systat -sensors` and also logged with `sensorsd`. Submitted by: Constantine A.

* Move some functions and definitions from uipc_socket2.c to uipc_socket.c:Robert Watson2006-06-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | - Move sonewconn(), which creates new sockets for incoming connections on listen sockets, so that all socket allocate code is together in uipc_socket.c. - Move 'maxsockets' and associated sysctls to uipc_socket.c with the socket allocation code. - Move kern.ipc sysctl node to uipc_socket.c, add a SYSCTL_DECL() for it to sysctl.h and remove lots of scattered implementations in various IPC modules. - Sort sodealloc() after soalloc() in uipc_socket.c for dependency order reasons. Statisticize soalloc() and sodealloc() as they are now required only in uipc_socket.c, and are internal to the socket implementation. After this change, socket allocation and deallocation is entirely centralized in one file, and uipc_socket2.c consists entirely of socket buffer manipulation and default protocol switch functions.

| | | | | | | | | | | | | | | | | | | sysctl routines and state. Add some code to use it for signalling the need to downconvert a data structure to 32 bits on a 64 bit OS when requested by a 32 bit app. I tried to do this in a generic abi wrapper that intercepted the sysctl oid's, or looked up the format string etc, but it was a real can of worms that turned into a fragile mess before I even got it partially working. With this, we can now run 'sysctl -a' on a 32 bit sysctl binary and have it not abort. Things like netstat, ps, etc have a long way to go. This also fixes a bug in the kern.ps_strings and kern.usrstack hacks. These do matter very much because they are used by libc_r and other things. Notes: svn path=/head/; revision=136404

Split munlock() in a similar way. Enable the RLIMIT_MEMLOCK checking code in kern_mlock(). Replace calls to vslock() and vsunlock() in the sysctl code with calls to kern_mlock() and kern_munlock() so that the sysctl code will obey the wired memory limits. Nuke the vslock() and vsunlock() implementations, which are no longer used. Add a member to struct sysctl_req to track the amount of memory that is wired to handle the request. Modify sysctl_wire_old_buffer() to return an error if its call to kern_mlock() fails. Only wire the minimum of the length specified in the sysctl request and the length specified in its argument list. It is recommended that sysctl handlers that use sysctl_wire_old_buffer() should specify reasonable estimates for the amount of data they want to return so that only the minimum amount of memory is wired no matter what length has been specified by the request. Modify the callers of sysctl_wire_old_buffer() to look for the error return. Modify sysctl_old_user to obey the wired buffer length and clean up its implementation.
