At each subsequent failure of the same + * operation we double the spin count, realizing an exponential + * backoff. + * + * When we spin, we try to use an operation that will cause the + * current cpu strand to block, and therefore make the core fully + * available to any other other runnable strands. There are two + * options, based upon cpu capabilities. + * + * On all cpus prior to SPARC-T4 we do three dummy reads of the + * condition code register. Each read blocks the strand for something + * between 40 and 50 cpu cycles. + * + * For SPARC-T4 and later we have a special "pause" instruction + * available. This is implemented using writes to register %asr27. + * The cpu will block the number of cycles written into the register, + * unless a disrupting trap happens first. SPARC-T4 specifically + * implements pause with a granularity of 8 cycles. Each strand has + * an internal pause counter which decrements every 8 cycles. So the + * chip shifts the %asr27 value down by 3 bits, and writes the result + * into the pause counter. If a value smaller than 8 is written, the + * chip blocks for 1 cycle. + * + * To achieve the same amount of backoff as the three %ccr reads give + * on earlier chips, we shift the backoff value up by 7 bits. (Three + * %ccr reads block for about 128 cycles, 1 << 7 == 128) We write the + * whole amount we want to block into the pause register, rather than + * loop writing 128 each time. + */ + #define BACKOFF_LIMIT (4 * 1024) #ifdef CONFIG_SMP @@ -11,16 +51,25 @@ #define BACKOFF_LABEL(spin_label, continue_label) \ spin_label -#define BACKOFF_SPIN(reg, tmp, label) \ - mov reg, tmp; \ -88: brnz,pt tmp, 88b; \ - sub tmp, 1, tmp; \ - set BACKOFF_LIMIT, tmp; \ - cmp reg, tmp; \ - bg,pn %xcc, label; \ - nop; \ - ba,pt %xcc, label; \ - sllx reg, 1, reg; +#define BACKOFF_SPIN(reg, tmp, label) \ + mov reg, tmp; \ +88: rd %ccr, %g0; \ + rd %ccr, %g0; \ + rd %ccr, %g0; \ + .section .pause_3insn_patch,"ax";\ + .word 88b; \ + sllx tmp, 7, tmp; \ + wr tmp, 0, %asr27; \ + clr tmp; \ + .previous; \ + brnz,pt tmp, 88b; \ + sub tmp, 1, tmp; \ + set BACKOFF_LIMIT, tmp; \ + cmp reg, tmp; \ + bg,pn %xcc, label; \ + nop; \ + ba,pt %xcc, label; \ + sllx reg, 1, reg; #else diff --git a/arch/sparc/include/asm/compat.h b/arch/sparc/include/asm/compat.h index cef99fb..830502fe 100644 --- a/arch/sparc/include/asm/compat.h +++ b/arch/sparc/include/asm/compat.h @@ -232,9 +232,10 @@ static inline void __user *arch_compat_alloc_user_space(long len) struct pt_regs *regs = current_thread_info()->kregs; unsigned long usp = regs->u_regs[UREG_I6]; - if (!(test_thread_flag(TIF_32BIT))) + if (test_thread_64bit_stack(usp)) usp += STACK_BIAS; - else + + if (test_thread_flag(TIF_32BIT)) usp &= 0xffffffffUL; usp -= len; diff --git a/arch/sparc/include/asm/processor_64.h b/arch/sparc/include/asm/processor_64.h index 4e5a483..721e25f 100644 --- a/arch/sparc/include/asm/processor_64.h +++ b/arch/sparc/include/asm/processor_64.h @@ -196,7 +196,22 @@ extern unsigned long get_wchan(struct task_struct *task); #define KSTK_EIP(tsk) (task_pt_regs(tsk)->tpc) #define KSTK_ESP(tsk) (task_pt_regs(tsk)->u_regs[UREG_FP]) -#define cpu_relax() barrier() +/* Please see the commentary in asm/backoff.h for a description of + * what these instructions are doing and how they have been choosen. + * To make a long story short, we are trying to yield the current cpu + * strand during busy loops. + */ +#define cpu_relax() asm volatile("\n99:\n\t" \ + "rd %%ccr, %%g0\n\t" \ + "rd %%ccr, %%g0\n\t" \ + "rd %%ccr, %%g0\n\t" \ + ".section .pause_3insn_patch,\"ax\"\n\t"\ + ".word 99b\n\t" \ + "wr %%g0, 128, %%asr27\n\t" \ + "nop\n\t" \ + "nop\n\t" \ + ".previous" \ + ::: "memory") /* Prefetch support.
