Walsworth† Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, Massachusetts 02138, USA; WebLesson 1: Spin locks ¶. The most basic primitive for locking is spinlock: static DEFINE_SPINLOCK (xxx_lock); unsigned long flags; spin_lock_irqsave (&xxx_lock, flags); ... critical section here .. spin_unlock_irqrestore (&xxx_lock, flags); The above is always safe. It will disable interrupts _locally_, but the spinlock itself will guarantee ...
Functional MRI Using Spin Lock Editing Preparation Pulses
WebAs preparation for dealing with both of those problems, protect the lists with a spinlock. The IRQ-unsafe version of the lock is used because IRQs are already disabled by local_lock_irqsave. spin_trylock is used in preparation for a time when local_lock could be used instead of lock_lock_irqsave. The per_cpu_pages still fits within the same ... WebJul 1, 2024 · The spinlock is a very simple single-holder lock. If a process attempts to acquire a spinlock and it is unavailable, the process will keep trying (spinning) until it can acquire the lock. This simplicity creates a small and fast lock. Like Mutex, there are two possible states in Spinlock: Locked or Unlocked. SpinLock in Linux Kernel Device Driver r4ryyyy
R1ρ at high spin-lock frequency could be a complementary
WebSpin-lock preparation with a RARE (rapid acquisition with relaxation enhancement) readout (9 different spin-lock times and 7 different spin-lock frequencies (FSLs)) and multi-echo UTE (ultrashort TE) pulses were developed to quantify R1ρ and R2 … WebJul 1, 2016 · (a) The STD-SL preparation contains a pair of spin-lock pulses applied with opposite phases and separated by a 180° refocusing pulse. (b) The PSC-SL preparation … WebOct 22, 2013 · We introduce a broadly applicable technique to create nuclear spin singlet states in organic molecules and other many-atom systems. We employ a novel pulse sequence to produce a spin-lock induced crossing (SLIC) of the spin singlet and triplet energy levels, which enables triplet-singlet polarization transfer and singlet-state … r4osteokine
