From: gosha <embedded@nm.ru> To: devel-kernel@lists.altlinux.org Subject: [d-kernel] info [немного недопонял, - В kernel 2.6.16 теперь ждущие блокировки spinlock() не работают?] Date: Sat, 17 Jun 2006 10:36:58 +0000 Message-ID: <547194163.20060617103658@nm.ru> (raw) Здравствуйте. Проблема с kernel 2.6.16.18/20.- Пробовал пересобрать (портировать) kernel 2.6.16.18: static spinlock_t lock; spin_lock_init(&lock); for(ir=0;ir<128;ir++) {spin_lock(&lock); printk("%s %s %d spinlock=%ld,%p\r\n", __FILE__, __FUNCTION__, __LINE__, ir, lock.raw_lock); } так она ни на одном мутексе не останавливается... И в include/linux/spinlock*.h ничего похожего на разблокировку/ блокировку .... --- include/linux/spinlock-up.h #define __raw_write_unlock(lock) do { (void)(lock); } while (0) #else /* DEBUG_SPINLOCK */ #define __raw_spin_is_locked(lock) ((void)(lock), 0) /* for sched.c and kernel_lock.c: */ # define __raw_spin_lock(lock) do { (void)(lock); } while (0) # define __raw_spin_unlock(lock) do { (void)(lock); } while (0) # define __raw_spin_trylock(lock) ({ (void)(lock); 1; }) #endif /* DEBUG_SPINLOCK */ #define __raw_read_can_lock(lock) (((void)(lock), 1)) #define __raw_write_can_lock(lock) (((void)(lock), 1)) #define __raw_spin_unlock_wait(lock) \ do { cpu_relax(); } while (__raw_spin_is_locked(lock)) #endif /* __LINUX_SPINLOCK_UP_H */ Спасибо. ---- -- С Уважением, gosha mailto:embedded@nm.ru
