Hi all,
I'm looking to cover a corner case for an upcoming test cycle. Is there a way to boot a RedHat Advanced Server 4 (update 3) installed on a Power PC machine to use a 32 bit kernel? This would be similar to what is done here -> https://www.unix.com/aix/26204-aix-platform.html

Hi.
I need to migrate the whole unix environment from a Unix mp-ras 32 bit to a Linux Suse 64 bit.
1) can i use cpio to copy the data?
2) can i just copy the users from unix to linux or do i have to create them by hand
3) are there any other concerns i should worry about?
thanx (1 Reply)

LEARN ABOUT SUNOS
atomic_set_long_excl
atomic_bits(9F) atomic_bits(9F)
NAME
atomic_bits, atomic_set_long_excl, atomic_clear_long_excl - atomic set and clear bit operations
SYNOPSIS
#include <sys/atomic.h>
int atomic_set_long_excl(volatile ulong_t *target, uint_t bit);
int atomic_clear_long_excl(volatile ulong_t *target, uint_t bit);
The atomic_set_long_excl() and atomic_clear_long_excl() functions perform an exclusive atomic bit set or clear operation on target. The
value of bit specifies the number of the bit to be modified within target. Bits are numbered from zero to one less than the maximum number
of bits in a long. If the value of bit falls outside of this range, the result of the operation is undefined.
The atomic_set_long_excl() and atomic_clear_long_excl() functions return 0 if bit was successfully set or cleared. They return -1 if bit
was already set or cleared.
No errors are defined.
These functions can be called from user or interrupt context.
