Signed-off-by: Paul Burton --- Changes in v2: - Declare the host syscalls conditionally upon whether both host & target define their numbers, to avoid compile time warnings/errors about the host syscall functions being unused when built for targets which don't support them. --- linux-user/syscall.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/linux-user/syscall.c b/linux-user/syscall.c index 1c300be..fb36f46 100644 --- a/linux-user/syscall.c +++ b/linux-user/syscall.c @@ -252,6 +252,12 @@ _syscall2(int, capget, struct __user_cap_header_struct *, header, struct __user_cap_data_struct *, data); _syscall2(int, capset, struct __user_cap_header_struct *, header, struct __user_cap_data_struct *, data); +#if defined(TARGET_NR_ioprio_get) && defined(__NR_ioprio_get) +_syscall2(int, ioprio_get, int, which, int, who) +#endif +#if defined(TARGET_NR_ioprio_set) && defined(__NR_ioprio_set) +_syscall3(int, ioprio_set, int, which, int, who, int, ioprio) +#endif static bitmask_transtbl fcntl_flags_tbl[] = { { TARGET_O_ACCMODE, TARGET_O_WRONLY, O_ACCMODE, O_WRONLY, }, @@ -9474,6 +9480,18 @@ abi_long do_syscall(void *cpu_env, int num, abi_long arg1, break; #endif +#if defined(TARGET_NR_ioprio_get) && defined(__NR_ioprio_get) + case TARGET_NR_ioprio_get: + ret = get_errno(ioprio_get(arg1, arg2)); + break; +#endif + +#if defined(TARGET_NR_ioprio_set) && defined(__NR_ioprio_set) + case TARGET_NR_ioprio_set: + ret = get_errno(ioprio_set(arg1, arg2, arg3)); + break; +#endif + default: unimplemented: gemu_log("qemu: Unsupported syscall: %d\n", num); -- 2.0.0
