And any race in updating the value in memory is harmless + * as the same value would simply be stored more than once. + * + * The only restriction for the algorithm to work properly is that this + * code must be executed at least once per each half period of the 32-bit + * counter to properly update the state bit in memory.

All reads preceding this primitive are guaranteed - * to access memory (but not necessarily other CPUs' caches) before any - * reads following this primitive that depend on the data return by - * any of the preceding reads. This primitive is much lighter weight than - * rmb() on most CPUs, and is never heavier weight than is - * rmb(). - * - * These ordering constraints are respected by both the local CPU - * and the compiler. - * - * Ordering is not guaranteed by anything other than these primitives, - * not even by data dependencies. See the documentation for - * memory_barrier() for examples and URLs to more information. - * - * For example, the following code would force ordering (the initial - * value of "a" is zero, "b" is one, and "p" is "&a"): - * - * <programlisting> - * CPU 0 CPU 1 - * - * b = 2; - * memory_barrier(); - * p = &b; q = p; - * read_barrier_depends(); - * d = *q; - * </programlisting> - * - * because the read of "*q" depends on the read of "p" and these - * two reads are separated by a read_barrier_depends(). However, - * the following code, with the same initial values for "a" and "b": - * - * <programlisting> - * CPU 0 CPU 1 - * - * a = 2; - * memory_barrier(); - * b = 3; y = b; - * read_barrier_depends(); - * x = a; - * </programlisting> - * - * does not enforce ordering, since there is no data dependency between - * the read of "a" and the read of "b". Therefore, on some CPUs, such - * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb() - * in cases like this where there are no data dependencies. - */ - -#define read_barrier_depends() do { } while(0) - -#ifdef CONFIG_CPU_HAS_SYNC -#define __sync() \ - __asm__ __volatile__( \ - ".set push\n\t" \ - ".set noreorder\n\t" \ - ".set mips2\n\t" \ - "sync\n\t" \ - ".set pop" \ - : /* no output */ \ - : /* no input */ \ - : "memory") -#else -#define __sync() do { } while(0) -#endif - -#define __fast_iob() \ - __asm__ __volatile__( \ - ".set push\n\t" \ - ".set noreorder\n\t" \ - "lw $0,%0\n\t" \ - "nop\n\t" \ - ".set pop" \ - : /* no output */ \ - : "m" (*(int *)CKSEG1) \ - : "memory") - -#define fast_wmb() __sync() -#define fast_rmb() __sync() -#define fast_mb() __sync() -#define fast_iob() \ - do { \ - __sync();

* TLB = translation look-aside buffer (term is stretched somewhat here) - * I = instruction (fetch accesses) - * D = data (load and store accesses) - * way = each TLB (ITLB and DTLB) consists of a number of "ways" - * that simultaneously match the virtual address of an access; - * a TLB successfully translates a virtual address if exactly - * one way matches the vaddr; if none match, it is a miss; - * if multiple match, one gets a "multihit" exception; - * each way can be independently configured in terms of number of - * entries, page sizes, which fields are writable or constant, etc. - * set = group of contiguous ways with exactly identical parameters - * ARF = auto-refill; hardware services a 1st-level miss by loading a PTE - * from the page table and storing it in one of the auto-refill ways; - * if this PTE load also misses, a miss exception is posted for s/w. - * min-wired = a "min-wired" way can be used to map a single (minimum-sized) - * page arbitrarily under program control; it has a single entry, - * is non-auto-refill (some other way(s) must be auto-refill), - * all its fields (VPN, PPN, ASID, CA) are all writable, and it - * supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current - * restriction is that this be the only page size it supports). - * - * TLB way entries are virtually indexed. - * TLB ways that support multiple page sizes: - * - must have all writable VPN and PPN fields; - * - can only use one page size at any given time (eg. setup at startup), - * selected by the respective ITLBCFG or DTLBCFG special register, - * whose bits n*4+3 .. n*4 index the list of page sizes for way n - * (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n); - * this list may be sparse for auto-refill ways because auto-refill - * ways have independent lists of supported page sizes sharing a - * common encoding with PTE entries; the encoding is the index into - * this list; unsupported sizes for a given way are zero in the list; - * selecting unsupported sizes results in undefined hardware behaviour; - * - is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition). -
