Unfortunately some of the - * semantics of the copy routine (exception handling) is difficult to express - * in C, so we have to play some tricks to get it to work. - * - * All the loads and stores are done via explicit asm() code in order to use - * the right space registers. - * - * Testing with various alignments and buffer sizes shows that this code is - * often >10x faster than a simple byte-at-a-time copy, even for strangely - * aligned operands. It is interesting to note that the glibc version - * of memcpy (written in C) is actually quite fast already. This routine is - * able to beat it by 30-40% for aligned copies because of the loop unrolling, - * but in some cases the glibc version is still slightly faster. This lends - * more credibility that gcc can generate very good code as long as we are - * careful. - * - * TODO: - * - cache prefetching needs more experimentation to get optimal settings - * - try not to use the post-increment address modifiers; they create additional - * interlocks - * - replace byte-copy loops with stybs sequences */ -#ifdef __KERNEL__ #include <linux/module.h> #include <linux/compiler.h> #include <linux/uaccess.h> -#define s_space "%%sr1" -#define d_space "%%sr2" -#else -#include "memcpy.h" -#define s_space "%%sr0" -#define d_space "%%sr0" -#define pa_memcpy new2_copy -#endif DECLARE_PER_CPU(struct exception_data, exception_data); -#define preserve_branch(label) do { \ - volatile int dummy = 0; \ - /* The following branch is never taken, it's just here to */ \ - /* prevent gcc from optimizing away our exception code. */ \ - if (unlikely(dummy != dummy)) \ - goto label; \ -} while (0) - #define get_user_space() (segment_eq(get_fs(), KERNEL_DS) ? 0 : mfsp(3)) #define get_kernel_space() (0) -#define MERGE(w0, sh_1, w1, sh_2) ({ \ - unsigned int _r; \ - asm volatile ( \ - "mtsar %3\n" \ - "shrpw %1, %2, %%sar, %0\n" \ - : "=r"(_r) \ - : "r"(w0), "r"(w1), "r"(sh_2) \ - ); \ - _r; \ -}) -#define THRESHOLD 16 - -#ifdef DEBUG_MEMCPY -#define DPRINTF(fmt, args...) do { printk(KERN_DEBUG "%s:%d:%s ", __FILE__, __LINE__, __func__ ); printk(KERN_DEBUG fmt, ##args ); } while (0) -#else -#define DPRINTF(fmt, args...) -#endif - -#define def_load_ai_insn(_insn,_sz,_tt,_s,_a,_t,_e) \ - __asm__ __volatile__ ( \ - "1:\t" #_insn ",ma " #_sz "(" _s ",%1), %0\n\t" \ - ASM_EXCEPTIONTABLE_ENTRY(1b,_e) \ - : _tt(_t), "+r"(_a) \ - : \ - : "r8") - -#define def_store_ai_insn(_insn,_sz,_tt,_s,_a,_t,_e) \ - __asm__ __volatile__ ( \ - "1:\t" #_insn ",ma %1, " #_sz "(" _s ",%0)\n\t" \ - ASM_EXCEPTIONTABLE_ENTRY(1b,_e) \ - : "+r"(_a) \ - : _tt(_t) \ - : "r8") - -#define ldbma(_s, _a, _t, _e) def_load_ai_insn(ldbs,1,"=r",_s,_a,_t,_e) -#define stbma(_s, _t, _a, _e) def_store_ai_insn(stbs,1,"r",_s,_a,_t,_e) -#define ldwma(_s, _a, _t, _e) def_load_ai_insn(ldw,4,"=r",_s,_a,_t,_e) -#define stwma(_s, _t, _a, _e) def_store_ai_insn(stw,4,"r",_s,_a,_t,_e) -#define flddma(_s, _a, _t, _e) def_load_ai_insn(fldd,8,"=f",_s,_a,_t,_e) -#define fstdma(_s, _t, _a, _e) def_store_ai_insn(fstd,8,"f",_s,_a,_t,_e) - -#define def_load_insn(_insn,_tt,_s,_o,_a,_t,_e) \ - __asm__ __volatile__ ( \ - "1:\t" #_insn " " #_o "(" _s ",%1), %0\n\t" \ - ASM_EXCEPTIONTABLE_ENTRY(1b,_e) \ - : _tt(_t) \ - : "r"(_a) \ - : "r8") - -#define def_store_insn(_insn,_tt,_s,_t,_o,_a,_e) \ - __asm__ __volatile__ ( \ - "1:\t" #_insn " %0, " #_o "(" _s ",%1)\n\t" \ - ASM_EXCEPTIONTABLE_ENTRY(1b,_e) \ - : \ - : _tt(_t), "r"(_a) \ - : "r8") - -#define ldw(_s,_o,_a,_t,_e) def_load_insn(ldw,"=r",_s,_o,_a,_t,_e) -#define stw(_s,_t,_o,_a,_e) def_store_insn(stw,"r",_s,_t,_o,_a,_e) - -#ifdef CONFIG_PREFETCH -static inline void prefetch_src(const void *addr) -{ - __asm__("ldw 0(" s_space ",%0), %%r0" : : "r" (addr)); -} - -static inline void prefetch_dst(const void *addr) -{ - __asm__("ldd 0(" d_space ",%0), %%r0" : : "r" (addr)); -} -#else -#define prefetch_src(addr) do { } while(0) -#define prefetch_dst(addr) do { } while(0) -#endif - -#define PA_MEMCPY_OK 0 -#define PA_MEMCPY_LOAD_ERROR 1 -#define PA_MEMCPY_STORE_ERROR 2 - -/* Copy from a not-aligned src to an aligned dst, using shifts.
