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.

(Direct + * calls are essentially free, because the call and return addresses + * are completely predictable.) + * + * For i386, these macros rely on the standard gcc "regparm(3)" calling + * convention, in which the first three arguments are placed in %eax, + * %edx, %ecx (in that order), and the remaining arguments are placed + * on the stack. All caller-save registers (eax,edx,ecx) are expected + * to be modified (either clobbered or used for return values). + * X86_64, on the other hand, already specifies a register-based calling + * conventions, returning at %rax, with parameteres going on %rdi, %rsi, + * %rdx, and %rcx. Note that for this reason, x86_64 does not need any + * special handling for dealing with 4 arguments, unlike i386. + * However, x86_64 also have to clobber all caller saved registers, which + * unfortunately, are quite a bit (r8 - r11) + * + * The call instruction itself is marked by placing its start address + * and size into the .parainstructions section, so that + * apply_paravirt() in arch/i386/kernel/alternative.c can do the + * appropriate patching under the control of the backend pv_init_ops + * implementation. + * + * Unfortunately there's no way to get gcc to generate the args setup + * for the call, and then allow the call itself to be generated by an + * inline asm. Because of this, we must do the complete arg setup and + * return value handling from within these macros. This is fairly + * cumbersome. + * + * There are 5 sets of PVOP_* macros for dealing with 0-4 arguments. + * It could be extended to more arguments, but there would be little + * to be gained from that. For each number of arguments, there are + * the two VCALL and CALL variants for void and non-void functions. + * + * When there is a return value, the invoker of the macro must specify + * the return type. The macro then uses sizeof() on that type to + * determine whether its a 32 or 64 bit value, and places the return + * in the right register(s) (just %eax for 32-bit, and %edx:%eax for + * 64-bit). For x86_64 machines, it just returns at %rax regardless of + * the return value size. + * + * 64-bit arguments are passed as a pair of adjacent 32-bit arguments + * i386 also passes 64-bit arguments as a pair of adjacent 32-bit arguments + * in low,high order + * + * Small structures are passed and returned in registers. The macro + * calling convention can't directly deal with this, so the wrapper + * functions must do this. + * + * These PVOP_* macros are only defined within this header. This + * means that all uses must be wrapped in inline functions. This also + * makes sure the incoming and outgoing types are always correct. + */ +#ifdef CONFIG_X86_32 +#define PVOP_VCALL_ARGS unsigned long __eax, __edx, __ecx +#define PVOP_CALL_ARGS PVOP_VCALL_ARGS +#define PVOP_VCALL_CLOBBERS "=a" (__eax), "=d" (__edx), \ + "=c" (__ecx) +#define PVOP_CALL_CLOBBERS PVOP_VCALL_CLOBBERS +#define EXTRA_CLOBBERS +#define VEXTRA_CLOBBERS +#else +#define PVOP_VCALL_ARGS unsigned long __edi, __esi, __edx, __ecx +#define PVOP_CALL_ARGS PVOP_VCALL_ARGS, __eax +#define PVOP_VCALL_CLOBBERS "=D" (__edi), \ + "=S" (__esi), "=d" (__edx), \ + "=c" (__ecx) + +#define PVOP_CALL_CLOBBERS PVOP_VCALL_CLOBBERS, "=a" (__eax) + +#define EXTRA_CLOBBERS , "r8", "r9", "r10", "r11" +#define VEXTRA_CLOBBERS , "rax", "r8", "r9", "r10", "r11" +#endif + +#ifdef CONFIG_PARAVIRT_DEBUG +#define PVOP_TEST_NULL(op) BUG_ON(op == NULL) +#else +#define PVOP_TEST_NULL(op) ((void)op) +#endif + +#define __PVOP_CALL(rettype, op, pre, post, ...) \ + ({ \ + rettype __ret; \ + PVOP_CALL_ARGS; \ + PVOP_TEST_NULL(op); \ + /* This is 32-bit specific, but is okay in 64-bit */ \ + /* since this condition will never hold */ \ + if (sizeof(rettype) > sizeof(unsigned long)) { \ + asm volatile(pre \ + paravirt_alt(PARAVIRT_CALL) \ + post \ + : PVOP_CALL_CLOBBERS \ + : paravirt_type(op), \ + paravirt_clobber(CLBR_ANY), \ + ##__VA_ARGS__ \ + : "memory", "cc" EXTRA_CLOBBERS); \ + __ret = (rettype)((((u64)__edx) << 32) | __eax); \ + } else { \ + asm volatile(pre \ + paravirt_alt(PARAVIRT_CALL) \ + post \ + : PVOP_CALL_CLOBBERS \ + : paravirt_type(op), \ + paravirt_clobber(CLBR_ANY), \ + ##__VA_ARGS__ \ + : "memory", "cc" EXTRA_CLOBBERS); \ + __ret = (rettype)__eax; \ + } \ + __ret; \ + }) +#define __PVOP_VCALL(op, pre, post, ...) \ + ({ \ + PVOP_VCALL_ARGS; \ + PVOP_TEST_NULL(op); \ + asm volatile(pre \ + paravirt_alt(PARAVIRT_CALL) \ + post \ + : PVOP_VCALL_CLOBBERS \ + : paravirt_type(op), \ + paravirt_clobber(CLBR_ANY), \ + ##__VA_ARGS__ \ + : "memory", "cc" VEXTRA_CLOBBERS); \ + }) + +#define PVOP_CALL0(rettype, op) \ + __PVOP_CALL(rettype, op, "", "") +#define PVOP_VCALL0(op) \ + __PVOP_VCALL(op, "", "") + +#define PVOP_CALL1(rettype, op, arg1) \ + __PVOP_CALL(rettype, op, "", "", "0" ((unsigned long)(arg1))) +#define PVOP_VCALL1(op, arg1) \ + __PVOP_VCALL(op, "", "", "0" ((unsigned long)(arg1))) + +#define PVOP_CALL2(rettype, op, arg1, arg2) \ + __PVOP_CALL(rettype, op, "", "", "0" ((unsigned long)(arg1)), \ + "1" ((unsigned long)(arg2))) +#define PVOP_VCALL2(op, arg1, arg2) \ + __PVOP_VCALL(op, "", "", "0" ((unsigned long)(arg1)), \ + "1" ((unsigned long)(arg2))) + +#define PVOP_CALL3(rettype, op, arg1, arg2, arg3) \ + __PVOP_CALL(rettype, op, "", "", "0" ((unsigned long)(arg1)), \ + "1"((unsigned long)(arg2)), "2"((unsigned long)(arg3))) +#define PVOP_VCALL3(op, arg1, arg2, arg3) \ + __PVOP_VCALL(op, "", "", "0" ((unsigned long)(arg1)), \ + "1"((unsigned long)(arg2)), "2"((unsigned long)(arg3))) + +/* This is the only difference in x86_64.
