https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211821 --- Comment #3 from Damon Zwolinski <freebsd@g3os.org> --- I think this is relevant: 1) On my emac, it looks like `hz is a pointer to an int.=20=20 # dtrace -n 'BEGIN { printf("`hz: %d\n", `hz); exit(0); }' dtrace: invalid probe specifier BEGIN { printf("%d\n", `hz); exit(0); }: printf( ) argument #2 is incompatible with conversion #1 prototype: conversion: %d prototype: char, short, int, long, or long long argument: int (*)() # dtrace -qn 'BEGIN { printf("`hz: %p, (int) `hz: %d\n", `hz, (int) `hz); exit(0); }' dtrace: buffer size lowered to 2m `hz: 3e8, (int) `hz: 1000 2) On my amd64 system (running in virtualbox on a macbook), `hz is an int. # uname -a FreeBSD macbook.local 10.3-RELEASE FreeBSD 10.3-RELEASE #0 r297264: Fri Mar= 25 02:10:02 UTC 2016 root@releng1.nyi.freebsd.org:/usr /obj/usr/src/sys/GENERIC amd64 # dtrace -qn 'BEGIN { printf("`hz: %d\n", `hz); exit(0); }' `hz: 1000 # dtrace -qn 'BEGIN { printf("&`hz: %p, `hz: %d\n", &`hz, `hz); exit(0); }' &`hz: ffffffff816a5d4c, `hz: 1000 3) I would bet they should be the same. Assuming sys/sys/kernel.h is the right file, hz is defined as an int there = so maybe it's not being brought into dtrace correctly on powerpc and/or on 32 = bit systems. Because I used trace(`hz), which tries to do the right thing (use= a cast if needed) above, it seemed like it worked. I'm also surprised the va= lue of hz is 1000 on my amd64 system. I thought it would be higher; I double checked to make sure I didn't copy the wrong text. I guess it doesn't mean what I thought it meant. --=20 You are receiving this mail because: You are the assignee for the bug.=
