| 2018-12-13 | irq/irq_sim: Store multiple interrupt offsets in a bitmap | Bartosz Golaszewski | 1 | -1/+1 | |
| Two threads can try to fire the irq_sim with different offsets and will end up fighting for the irq_work asignment. Thomas Gleixner suggested a solution based on a bitfield where we set a bit for every offset associated with an interrupt that should be fired and then iterate over all set bits in the interrupt handler. This is a slightly modified solution using a bitmap so that we don't impose a limit on the number of interrupts one can allocate with irq_sim.

| 2017-08-16 | genirq/irq_sim: Add a devres variant of irq_sim_init() | Bartosz Golaszewski | 1 | -0/+3 | |
| Add a resource managed version of irq_sim_init(). This can be conveniently used in device drivers.

| 2017-08-16 | genirq/irq_sim: Add a simple interrupt simulator framework | Bartosz Golaszewski | 1 | -0/+41 | |
| Implement a simple, irq_work-based framework for simulating interrupts. Currently the API exposes routines for initializing and deinitializing the simulator object, enqueueing the interrupts and retrieving the allocated interrupt numbers based on the offset of the dummy interrupt in the simulator struct.
