2005-07-31do not allocate huge kinfo_proc2 and eproc structures on the stack.Theo de Raadt
allocate them on startup if needed, and free them when done. discussion with pascoe, tested by dlg
2005-06-08Add KERN_CPTIME2 on systems where __HAVE_CPUINFO is defined, exposesTodd C. Miller
spc_cp_time member of struct schedstate_percpu (per-cpu stats). From art@ during the hackathon.
2005-06-04let the arc4random sysctl write out up to 256 bytes at once.Ted Unangst
ok + input deraadt miod
2005-05-24add a new field to vm_space and use it to track the number of anonTed Unangst
pages a process uses. this is now the userland "data size" value. ok art deraadt tdeval. thanks testers.
2005-03-10split out uidinfo from kern_proc.c private, use it to store lock count,Ted Unangst
restrict lock count per uid to a global limit, add sysctl to adjust limit. this prevents a user from creating too many locks. problem noticed by devon o'dell. ok deraadt miod pedro
2004-12-24Do not provide the KERN_EMUL, KERN_EVCOUNT, KERN_INTRCNT, KERN_PROC* andMiod Vallat
HW_SENSORS sysctl trees if option SMALL_KERNEL. ok deraadt@
2004-11-26Kill __HAVE_EVCOUNT, now that all architectures provide them.Miod Vallat
2004-10-14a more reasonable limit for the stackgap_random; found by openbsd@hunger.huMichael Shalayeff
2004-09-23change KERN_INTRCNT_CNT to return a quad; ok teduTheo de Raadt
2004-09-15Check for num < 0 in sysctl_sensors(); from Patrick Latifi.Alexander Yurchenko
ok millert@
2004-07-28This touches only MI code, and adds new time keeping code. TheThorsten Lockert
code is all conditionalized on __HAVE_TIMECOUNTER, and not enabled on any platforms. adjtime(2) support exists, courtesy of nordin@, sysctl(2) support and a concept of quality for each time source attached exists. High quality time sources exists for PIIX4 ACPI timer as well as some AMD power management chips. This will have to be redone once we actually add ACPI support (at that time we need to use the ACPI interfaces to get at these clocks). ok art@ ken@ miod@ jmc@ and many more
2004-06-28Add new, generic ``evcount'' event counter API to the kernel. From art@,Aaron Campbell
with modifications from me. Includes code for generic interrupt counter fetching via sysctl. deraadt@ tholo@ drahn@ millert@ ok
2004-06-25Instead of accessing ci_dev (that's an MI field), provide a marco thatArtur Grabowski
translates a cpu_info structure into a human-readable cpu number. drahn@ deraadt@ ok
2004-06-24Remove the 8 page limit for sysctl_proc_args after discussing with Theo.Todd C. Miller
Add trivial support for passing a NULL pointer for the argv buffer; currently just returns ARG_MAX for KERN_PROC_ARGV and KERN_PROC_ENV.
2004-06-20Another merge error from smp branch.Artur Grabowski
Found by otto@drijf.net deraadt@ ok
2004-06-16export cpu# instead of apid#; art okTheo de Raadt
2004-06-13debranch SMP, have funNiklas Hallqvist
2004-06-09Merge in a piece of the SMP branch into HEAD.Artur Grabowski
Introduce the cpu_info structure, p_cpu field in struct proc and global scheduling context and various changed code to deal with this. At the moment no architecture uses this stuff yet, but it will allow us slow and controlled migration to the new APIs. All new code is ifdef:ed out. ok deraadt@ niklas@
2004-06-08pull ncpus support from smp tree into main branch.Marco S Hyman
remove alpha specific definition of ncpus. OK (and tested on alpha) deraadt@
2004-05-27apm restores perflevel after resume; some cpus are forgetful.Ted Unangst
update cpu even with 100 -> 100 setperf changes, in case saved value has gotten out of sync. from grange@ ok deraadt@ grange@
2004-05-23bad stuff escaped by accidentTed Unangst
2004-05-23according to fork1(9), retval is optional. make it so.Ted Unangst
from form@pdp-11.org.ru via mpech. ok millert
2004-04-19introduce a new km_page allocator that gets pages from kernel_map usingTed Unangst
an interrupt safe thread. use this as the new backend for mbpool and mclpool, eliminating the mb_map. introduce a sysctl kern.maxclusters which controls the limit of clusters allocated. testing by many people, works everywhere but m68k. ok deraadt@ this essentially deprecates the NMBCLUSTERS option, don't use it. this should reduce pressure on the kmem_map and the uvm reserve of static map entries.
2004-04-15rework access to emulations slightly in an effort to both merge andTed Unangst
separate exec format from emulation. consistent naming of freebsd emuls. not much in the way of functional changes yet. testing and ok deraadt@ and others along the way.
2004-02-29Check for negative numbers.Tobias Weingartner
ok grange@
2004-02-27Move setperf_prio to the machdep code, requested by deraadt@Alexander Yurchenko

2004-02-27Introduce simple priorities mechanism so that concurrentAlexander Yurchenko
hw.setperf handlers don't override each other. Problem reported and tested by danh@. ok tedu@ deraadt@
2004-02-15add sysctl_int_arr() API similar to BSD/OS; ok itojun, deraadt, miod, henningMarkus Friedl
2004-02-15new arg to disk_unbusy, to record separate read/write statistics.Ted Unangst
looked at by various, testing henning@ mcbride@ dan weeks mostly from netbsd via Pedro Martelletto <pbastos@rdc.puc-rio.br>

from the underlying callbacks. Testing hppa mickey@, ppc drahn@ Ok markus@ tedu@
2004-01-07Add p_rlim_rss_cur for ps "lim" field. OK deraadt@Todd C. Miller
2004-01-07no kern_watchdog for SMALL_KERNEL; ok deraadt@Markus Friedl
2004-01-07Unbreak KERN_PROC_KTHREAD. Explicitly list KERN_PROC_KTHREAD inTodd C. Miller
the sysctl_doproc() switch so it does not match the default case (EINVAL). deraadt@ OK.
2004-01-07Add p_emul to kinfo_proc2 for psTodd C. Miller
2004-01-07Implement KERN_PROC2 sysctl from NetBSD. This will allow us toTodd C. Miller
have ps and friends be independent of changes in struct proc et al in the kernel. OK deraadt@
2003-12-18add new hw sysctls, cpuspeed and setperf to control cpu frequency.Ted Unangst
convert longrun support to use new sysctls. add enhanced speedstep support, based on code by Michael Eriksson. idea, help testing & ok deraadt@
2003-11-23Check correct array index KERN_VNODE; from Alistair KerrTodd C. Miller
Closes PR 3571 as per on icb.
2003-10-26per deraadt@ request, don't permit insanely large stackgap values.Ted Unangst
2003-10-24refactor stackgap sysctl. prompted by a bug report from Michael Coulter.Ted Unangst
ok deraadt@ markus@
2003-08-23remove native emulations from emulsw. you can't change them and probablyTed Unangst
aren't interested, so keep them out of the sysctl. ok deraadt

2003-08-23allow disabling a emul after enabling it; tedu@ ok.Federico G. Schwindt
2003-08-21emulation is now controlled by sysctl. changes:Ted Unangst
add e_flags to struct emul. this stores on/off and native flags. check for emul enabled in check_exec(). gather all the emuls into a emulsw so a sysctl can find them. create sysctl. move maxhdrsiz calcualation into init_main so it cleans up sys_execve codepath. teach sysctl utility to grok kern.emul hierarchy. requested and ok deraadt@ some comments from mickey@
2003-08-15change arguments to suser. suser now takes the process, and a flagsTed Unangst
argument. old cred only calls user suser_ucred. this will allow future work to more flexibly implement the idea of a root process. looks like something i saw in freebsd, but a little different. use of suser_ucred vs suser in file system code should be looked at again, for the moment semantics remain unchanged. review and input from art@ testing and further review miod@
2003-08-06Remove some double semicolons (hmm, do two semis equal a maxi?).Todd C. Miller
I've skipped the GNU stuff for now. From Patrick Latifi.

rescinded 22 July 1999. Proofed by myself and Theo.

2003-04-25sysctl front-end for the hardware monitoring sensors. This addsAlexander Yurchenko
new node hw.sensors; information from the sensors can be obtained via hw.sensors.n, where n is a sensor number. All values are read only for now. Documentation and back-end drivers are comming. Tested by henning@ and millert@. Four oks from henning@ and one from millert@.
2003-01-21add kern.watchdog sysctl and generic watchdog interface;Markus Friedl
