* Drop luna88k bitsMarin Ramesa2013-09-091-1/+1
| | | | | * device/tty.h [luna88k]: Remove ifdef and include for nonexistent header files. * kern/debug.c: Remove check for luna88k.
* kern: add missing prototypeMarin Ramesa2013-07-181-0/+2
| | | | * kern/lock.h (db_show_all_slocks): Add prototype.
* (slab_info): fix format warningsMarin Ramesa2013-06-291-1/+1
| | | | * kern/slab.c (slab_info): Fix format for vm_size_t.
* Fix object construction in the slab allocatorRichard Braun2013-06-091-4/+10
| | | | | | | | There is currently no actual use of constructors, which is why this bug has been long overlooked. * kern/slab.c (kmem_cpu_pool_fill): Call constructor on buffers unless verification is enabled for the cache, or the constructor is NULL.
* Comment unused variableMarin Ramesa2013-06-041-3/+4
| | | | * kern/ipc_mig.c (syscall_device_write_request): Comment unused variable.

| * Fix yet another locking error in the slab allocatorRichard Braun2013-06-021-0/+1
| | | | | | | | | | * kern/slab.c (kmem_cache_free): Relock cache before retrying releasing an object to the CPU pool layer.
* | Remove unused variableMiguel Figueiredo2013-06-021-1/+0
|/ | | | * kern/act.c (act_create): Remove unused variable.
* Remove unneeded variable initializationMiguel Figueiredo2013-05-191-1/+1
| | | | | * kern/thread.c (thread_force_terminate): Remove unneeded variable initialization.
* Remove duplicate lineSamuel Thibault2013-05-191-1/+0
| | | | | | | Reported by Miguel Figueiredo * kern/thread.c (thread_create): Remove duplicate reset of new_thread->pc_sample.buffer to 0.
* Reduce fragmentation in the slab allocatorRichard Braun2013-05-161-2/+5
| | | | | | | | | | This reverts a change brought when reworking slab lists handling that made the allocator store slabs in LIFO order, whatever their reference count. While it's fine for free slabs, it actually increased fragmentation for partial slabs. * kern/slab.c (kmem_cache_alloc_from_slab): Insert slabs that become partial at the end of the partial slabs list.
* Rename list_insert to list_insert_headRichard Braun2013-05-162-5/+5
| | | | | | | | This change increases clarity. * kern/list.h (list_insert): Rename to ... (list_insert_head): ... this. * kern/slab.c: Update calls to list_insert.
* Drop unused variablesMiguel Figueiredo2013-05-131-1/+0
| | | | * kern/slab.c (kalloc_init): Remove unused variables.
* Optimize slab reapingRichard Braun2013-04-211-13/+10
| | | | | | | | 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.
* Rework slab lists handlingRichard Braun2013-04-212-81/+8
| | | | | | | | | | | | 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.

* Add the mach_print debugging system callRichard Braun2013-01-223-1/+22
| | | | | | | | | | | | 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.

| * Add function to dump a raw summary of the slab allocator stateRichard Braun2013-01-082-0/+34
| | | | | | | | | | | | | | | | | | 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.

|/ | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As it is intended to completely replace the zone allocator, remove it on the way. So long to the venerable code ! * Makefrag.am (libkernel_a_SOURCES): Add kern/slab.{c,h}, remove kern/kalloc.c and kern/zalloc.{c,h}. * configfrag.ac (SLAB_VERIFY, SLAB_USE_CPU_POOLS): Add defines. * i386/Makefrag.am (libkernel_a_SOURCES): Remove i386/i386/zalloc.h. * i386/configfrag.ac (CPU_L1_SHIFT): Remove define. * include/mach_debug/slab_info.h: New file. * kern/slab.c: Likewise. * kern/slab.h: Likewise. * i386/i386/zalloc.h: Remove file. * include/mach_debug/zone_info.h: Likewise. * kern/kalloc.c: Likewise. * kern/zalloc.c: Likewise. * kern/zalloc.h: Likewise.
