2013-04-21Optimize slab reapingRichard Braun
Instead of walking the list of free slabs while holding the cache lock, detach the list from the cache and directly compute the final count values, and destroy slabs after releasing the cache lock. * kern/slab.c (kmem_cache_reap): Optimize.
2013-04-21Rework slab lists handlingRichard Braun
Don't enforce strong ordering of partial slabs. Separating partial slabs from free slabs is already effective against fragmentation, and sorting would sometimes cause pathological scalability issues. In addition, store new slabs (whether free or partial) in LIFO order for better cache usage. * kern/slab.c (kmem_cache_grow): Insert new slab at the head of the slabs list. (kmem_cache_alloc_from_slab): Likewise. In addition, don't sort partial slabs. (kmem_cache_free_to_slab): Likewise. * kern/slab.h: Remove comment about partial slabs sorting.
2013-04-21Fix locking error in the slab allocatorRichard Braun
* kern/slab.c (kmem_cache_free): Lock cache before releasing an object to the slab layer.
2013-03-11Update BASEPRI_USERSamuel Thibault
* kern/sched.h (BASEPRI_USER): Increase to 25.
2013-03-06Increase number of prioritiesSamuel Thibault
* kern/sched.h (NRQS): Increase to 50.
2013-03-05Do not hardcode maximum priority valueSamuel Thibault
* kern/sched_prim.c (do_priority_computation): Replace 31 with NRQS - 1. idle_thread: Likewise.
2013-01-22Add the mach_print debugging system callRichard Braun
The purpose of this system call is to help debugging in situations where it's desirable to bypass the mach_msg call entirely. * include/mach/syscall_sw.h (mach_print): Generate system call code. * kern/syscall_subr.c: Include <kern/printf.h>. [MACH_KDB] (mach_print): New function. * kern/syscall_subr.h (mach_print): New prototype. * kern/syscall_sw.c [MACH_KDB] (mach_trap_table): Declare mach_print system call.

2013-01-08Add function to dump a raw summary of the slab allocator stateRichard Braun
The purpose of this function is to allow kernel code to display the state of the slab caches in situations where the host_slab_info RPC wouldn't be available, e.g. before a panic. * kern/slab.c (slab_info): New function. * kern/slab.h: Add declaration for slab_info.

2012-12-23Make thread_suspend wait for !TH_UNINTSamuel Thibault
0a55db5 made thread_suspend return KERN_FAILURE when the target thread is in TH_UNINT state. That however is not currently handled by libc, and it's more useful to just wait for the thread to get interruptible. * kern/sched_prim.c (thread_invoke): Wake NEW_THREAD->STATE for thread_suspend. * kern/thread.c (thread_suspend): Wait on NEW_THREAD->STATE as long as THREAD has TH_UNINT.
2012-12-05Fix kernel task creation timeRichard Braun

2012-07-08Fix slab collection timingRichard Braun
The slab garbage collector uses sched_tick as its time reference, which is increased every seconds, while the interval is expressed in clock ticks. Use the proper time reference instead. * kern/slab.c (kmem_gc_last_tick): Declare as unsigned long. (slab_collect): Use elapsed_ticks instead of sched_tick.
2012-07-07Increase the slab collection intervalRichard Braun
* kern/slab.c (KMEM_GC_INTERVAL): Increase to 5 seconds.
2012-07-07Allocate kernel thread stacks out of kmem_mapRichard Braun
The kernel submaps eat most of the available kernel space. Using the main kernel map for thread stacks sometimes lead to exhaustion when many threads are created. Use kmem_map instead to increase this limit. * kern/thread.c (stack_alloc): Use kmem_map instead of kernel_map for stack allocation. (stack_collect): Likewise for release.

2012-01-22Fix build on 64bit hostSamuel Thibault
When stealing the memset function from the 32bit host libc on a 64bit host system, glibc tends to bring unwanted references to _Unwind_Resume, __gcc_personality_v0, etc. So let's stop stealing memset. * kern/strings.c (memset): New function. * Makefile.am (clib_routines): Remove memset.
