| | | | | | | | | | | | | | | | | | where physical addresses larger than virtual addresses, such as i386s with PAE. - Use this to represent physical addresses in the MI vm system and in the i386 pmap code. This also changes the paddr parameter to d_mmap_t. - Fix printf formats to handle physical addresses >4G in the i386 memory detection code, and due to kvtop returning vm_paddr_t instead of u_long. Note that this is a name change only; vm_paddr_t is still the same as vm_offset_t on all currently supported platforms.

| | | | | | | | | | | | | | | | | | | allocated slabs and bucket caches for free items. It will not go ask the vm for pages. This differs from M_NOWAIT in that it not only doesn't block, it doesn't even ask. - Add a new zcreate option ZONE_VM, that sets the BUCKETCACHE zflag. This tells uma that it should only allocate buckets out of the bucket cache, and not from the VM. It does this by using the M_NOVM option to zalloc when getting a new bucket. This is so that the VM doesn't recursively enter itself while trying to allocate buckets for vm_map_entry zones. If there are already allocated buckets when we get here we'll still use them but otherwise we'll skip it. - Use the ZONE_VM flag on vm map entries and pv entries on x86.

| | | | | | | | | | | | | | | Updated the kmemzones logic such that the ks_size bitmap can be used as an index into it to report the size of the zone used. Create the kern.malloc sysctl which replaces the kvm mechanism to report similar data. This will provide an easy place for statistics aggregation if malloc_type statistics become per cpu data. Add some code ifdef'd under MALLOC_PROFILING to facilitate a tool for sizing the malloc buckets. Notes: svn path=/head/; revision=94729

| | | | | | | | | | | | - Callers of asleep() and await() have been converted to calling tsleep(). The only caller outside of M_ASLEEP was the ata driver, which called both asleep() and await() with spl-raised, so there was no need for the asleep() and await() pair. M_ASLEEP was unused.

* sys/malloc.h:Bruce Evans2000-06-141-1/+1
| | | | | | | | | | | | | | | Order the SYSINIT() for MALLOC_DEFINE() correctly so that malloc() doesn't have to waste time initializing itself. The (SI_SUB_KMEM, SI_ORDER_ANY) order was shared with syscons' SYSINIT() for scmeminit(), and scmeminit() calls malloc(), so malloc() initialization was not always complete on the first call to malloc(). kern/kern_malloc.c: - Removed self-initialization in malloc(). - Removed half-baked sanity check in free(). Trust MALLOC_DEFINE(). Notes: svn path=/head/; revision=61689
* Removed support for generating inline code for MALLOC() and FREE()Bruce Evans2000-06-141-45/+4
| | | | | | | | | | | | | | | | | | | | | | in the dysfunctional !KMEMSTATS case. This hasn't compiled since rev.1.31 of kern_malloc.c quietly removed the core of the support for the !KMEMSTATS case. I fixed it to see if it was worth saving and found that (as usual) inlining just wasted space and increased complexity without significantly affecting time, at least for the lmbench2 micro-benchmark on a Celeron. The space bloat was surprisingly large - the text size increased from 1700K to 1840K for a version with the entire malloc() family inlined. Removed even older garbage (kmemxtob() and btokmemx() macros). Attempt to deprecate MALLOC() and FREE(). Given current compilers (gcc-2.x or C99), they don't do anything that (safe) function-like macros or inline functions named malloc() and free() couldn't do. Fixed missing casts of macro args in MALLOC() and FREE(). Notes: svn path=/head/; revision=61680

* Force the "calls" count for malloc types to be 64 bit where it keeps trackPeter Wemm1999-10-011-2/+2
| | | | | | | | | | | | of the number of times a particular type has been used. It's rather easy to overflow. One site I'm looking at seems to do it in a matter of days. On the Alpha this is a no-op since 'long' is 64 bit already. The sole user of this interface seems to be vmstat -m and friends which will need a recompile. The overheads of using a 64 bit int should be pretty light as the kernel just does "calls++" type operations and that's it. Notes: svn path=/head/; revision=51842
