/* |
* The SLAB allocator is closely modelled after OpenSolaris SLAB allocator |
* http://www.usenix.org/events/usenix01/full_papers/bonwick/bonwick_html/ |
* |
* with the following exceptions: |
* - empty SLABS are deallocated immediately |
* (in Linux they are kept in linked list, in Solaris ???) |
* - empty magazines are deallocated when not needed |
* (in Solaris they are held in linked list in slab cache) |
* |
* Following features are not currently supported but would be easy to do: |
* - cache coloring |
* - dynamic magazine growing (different magazine sizes are already |
* supported, but we would need to adjust allocating strategy) |
* |
* The SLAB allocator supports per-CPU caches ('magazines') to facilitate |
* good SMP scaling. |
* |
* When a new object is being allocated, it is first checked, if it is |
* available in CPU-bound magazine. If it is not found there, it is |
* allocated from CPU-shared SLAB - if partial full is found, it is used, |
* otherwise a new one is allocated. |
* |
* When an object is being deallocated, it is put to CPU-bound magazine. |
* If there is no such magazine, new one is allocated (if it fails, |
* the object is deallocated into SLAB). If the magazine is full, it is |
* put into cpu-shared list of magazines and new one is allocated. |
* |
* The CPU-bound magazine is actually a pair of magazine to avoid |
* thrashing when somebody is allocating/deallocating 1 item at the magazine |
* size boundary. LIFO order is enforced, which should avoid fragmentation |
* as much as possible. |
* |
* Every cache contains list of full slabs and list of partialy full slabs. |
* Empty SLABS are immediately freed (thrashing will be avoided because |
* of magazines). |
* |
* The SLAB information structure is kept inside the data area, if possible. |
* The cache can be marked that it should not use magazines. This is used |
* only for SLAB related caches to avoid deadlocks and infinite recursion |
* (the SLAB allocator uses itself for allocating all it's control structures). |
* |
* The SLAB allocator allocates lot of space and does not free it. When |
* frame allocator fails to allocate the frame, it calls slab_reclaim(). |
* It tries 'light reclaim' first, then brutal reclaim. The light reclaim |
* releases slabs from cpu-shared magazine-list, until at least 1 slab |
* is deallocated in each cache (this algorithm should probably change). |
* The brutal reclaim removes all cached objects, even from CPU-bound |
* magazines. |
* |
* TODO: For better CPU-scaling the magazine allocation strategy should |
* be extended. Currently, if the cache does not have magazine, it asks |
* for non-cpu cached magazine cache to provide one. It might be feasible |
* to add cpu-cached magazine cache (which would allocate it's magazines |
* from non-cpu-cached mag. cache). This would provide a nice per-cpu |
* buffer. The other possibility is to use the per-cache |
* 'empty-magazine-list', which decreases competing for 1 per-system |
* magazine cache. |
* |
* - it might be good to add granularity of locks even to slab level, |
* we could then try_spinlock over all partial slabs and thus improve |
* scalability even on slab level |
