* Do not provide the KERN_EMUL, KERN_EVCOUNT, KERN_INTRCNT, KERN_PROC* andmiod2004-12-241-3/+21

* This touches only MI code, and adds new time keeping code. Thetholo2004-07-281-1/+12
| | | | | | | | | | | | | | | 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
* Add new, generic ``evcount'' event counter API to the kernel. From art@,aaron2004-06-281-1/+16
| | | | | with modifications from me. Includes code for generic interrupt counter fetching via sysctl. deraadt@ tholo@ drahn@ millert@ ok

* Remove the 8 page limit for sysctl_proc_args after discussing with Theo.millert2004-06-241-7/+9
| | | | | 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.

* Merge in a piece of the SMP branch into HEAD.art2004-06-091-1/+5
| | | | | | | | | | | 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@
* pull ncpus support from smp tree into main branch.marc2004-06-081-2/+2
| | | | | remove alpha specific definition of ncpus. OK (and tested on alpha) deraadt@
* apm restores perflevel after resume; some cpus are forgetful.tedu2004-05-271-7/+6

| | | | | | | | | | | | 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.

| | | | | | | | | 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@

| | | | | | | | | 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@

* Make SysV-style shared memory and semaphore limits sysctl'able.millert2002-12-171-8/+37
| | | | | | | | | | | | Instead of allocating a static amount of memory for the data structures via valloc() in allocsys(), allocate things dynamically using pool(9) when possible and malloc(9) when not. The various members of struct seminfo and struct shminfo are in kern.seminfo and kern.shminfo respectively (not all members of kern.seminfo are changable). The data structures used still leave something to be desired but things are not made worse in that respect by this commit.
