From aecde502e9bb20a30b0f111b5a690af1746b78ef Mon Sep 17 00:00:00 2001 From: John David Anglin Date: Sun, 23 Jun 2024 19:39:28 -0400 Subject: hppa/vdso: Add wrappers for vDSO functions The upcoming parisc (hppa) v6.11 Linux kernel will include vDSO support for gettimeofday(), clock_gettime() and clock_gettime64() syscalls for 32- and 64-bit userspace. The patch below adds the necessary glue code for glibc. Signed-off-by: Helge Deller Changes in v2: - add vsyscalls for 64-bit too --- sysdeps/unix/sysv/linux/hppa/sysdep.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'sysdeps/unix') diff --git a/sysdeps/unix/sysv/linux/hppa/sysdep.h b/sysdeps/unix/sysv/linux/hppa/sysdep.h index ee82fbd364..af62f7501e 100644 --- a/sysdeps/unix/sysv/linux/hppa/sysdep.h +++ b/sysdeps/unix/sysv/linux/hppa/sysdep.h @@ -468,6 +468,18 @@ L(pre_end): ASM_LINE_SEP \ #define CLOB_ARGS_1 CLOB_ARGS_2, "%r25" #define CLOB_ARGS_0 CLOB_ARGS_1, "%r26" +#define VDSO_NAME "LINUX_6.11" +#define VDSO_HASH 182951793 + +#ifdef __LP64__ +# define HAVE_CLOCK_GETTIME_VSYSCALL "__vdso_clock_gettime" +# define HAVE_GETTIMEOFDAY_VSYSCALL "__vdso_gettimeofday" +#else +# define HAVE_CLOCK_GETTIME_VSYSCALL "__vdso_clock_gettime" +# define HAVE_CLOCK_GETTIME64_VSYSCALL "__vdso_clock_gettime64" +# define HAVE_GETTIMEOFDAY_VSYSCALL "__vdso_gettimeofday" +#endif /* __LP64__ */ + #endif /* __ASSEMBLER__ */ #endif /* _LINUX_HPPA_SYSDEP_H */ -- cgit 1.4.1
