When an hwirq is mapped, an irq_desc is allocated and the hwirq is used as the lookup key for the radix tree. The tree map is a good choice if the hwirq number can be very large since it doesn’t need to allocate a table as large as the largest hwirq number. how to sharpen fiskars garden shearsWeb1 // SPDX-License-Identifier: GPL-2.0: 2 /* 3 * Copyright (C) 1992, 1998-2006 Linus Torvalds, Ingo Molnar: 4 * Copyright (C) 2005-2006 Thomas Gleixner how to sharpen fiskars easy action scissorsWebInterrupts and Interrupt Handling.
