The kmem SLAB + * allocator allocates slabs from it. Then the generic allocation functions + * kmem_{alloc,zalloc,free}() are layered on top of SLAB allocators. + * + * On Linux, the primary means of doing allocations is via kmalloc(), which + * is similarly layered on top of something called the buddy allocator. The + * buddy allocator is not available to kernel modules, it uses physical + * memory addresses rather than virtual memory addresses and is prone to + * fragmentation. + * + * Linux sets aside a relatively small address space for in-kernel virtual + * memory from which allocations can be done using vmalloc(). It might seem + * like a good idea to use vmalloc() to implement something similar to + * Illumos' allocator. However, this has the following problems: + * + * 1. Page directory table allocations are hard coded to use GFP_KERNEL. + * Consequently, any KM_PUSHPAGE or KM_NOSLEEP allocations done using + * vmalloc() will not have proper semantics. + * + * 2. Address space exhaustion is a real issue on 32-bit platforms where + * only a few 100MB are available. The kernel will handle it by spinning + * when it runs out of address space. + * + * 3. All vmalloc() allocations and frees are protected by a single global + * lock which serializes all allocations. + * + * 4. Accessing /proc/meminfo and /proc/vmallocinfo will iterate the entire + * list. The former will sum the allocations while the latter will print + * them to user space in a way that user space can keep the lock held + * indefinitely. When the total number of mapped allocations is large + * (several 100,000) a large amount of time will be spent waiting on locks. + * + * 5. Linux has a wait_on_bit() locking primitive that assumes physical + * memory is used, it simply does not work on virtual memory. Certain + * Linux structures (e.g. the superblock) use them and might be embedded + * into a structure from Illumos. This makes using Linux virtual memory + * unsafe in certain situations. + * + * It follows that we cannot obtain identical semantics to those on Illumos. + * Consequently, we implement the kmem_{alloc,zalloc,free}() functions in + * such a way that they can be used as drop-in replacements for small vmem_* + * allocations (8MB in size or smaller) and map vmem_{alloc,zalloc,free}() + * to them. + */ + +#define vmem_alloc(sz, fl) spl_vmem_alloc((sz), (fl), __func__, __LINE__) +#define vmem_zalloc(sz, fl) spl_vmem_zalloc((sz), (fl), __func__, __LINE__) +#define vmem_free(ptr, sz) spl_vmem_free((ptr), (sz)) + +extern void *spl_vmem_alloc(size_t sz, int fl, const char *func, int line); +extern void *spl_vmem_zalloc(size_t sz, int fl, const char *func, int line); +extern void spl_vmem_free(const void *ptr, size_t sz); + +int spl_vmem_init(void); +void spl_vmem_fini(void); + +#endif /* _SPL_VMEM_H */ diff --git a/include/sys/vmsystm.h b/include/sys/vmsystm.h index adff774..2fa1695 100644 --- a/include/sys/vmsystm.h +++ b/include/sys/vmsystm.h @@ -33,115 +33,12 @@ #include #include -/* These values are loosely coupled with the VM page reclaim. - * Linux uses its own heuristics to trigger page reclamation, and - * because those interface are difficult to interface with.
