ae6e843fe08d0e Bob Pearson 2021-09-14 10 /* Implements a simple circular buffer that is shared between user
ae6e843fe08d0e Bob Pearson 2021-09-14 11 * and the driver and can be resized. The requested element size is
ae6e843fe08d0e Bob Pearson 2021-09-14 12 * rounded up to a power of 2 and the number of elements in the buffer
ae6e843fe08d0e Bob Pearson 2021-09-14 13 * is also rounded up to a power of 2. Since the queue is empty when
ae6e843fe08d0e Bob Pearson 2021-09-14 14 * the producer and consumer indices match the maximum capacity of the
ae6e843fe08d0e Bob Pearson 2021-09-14 15 * queue is one less than the number of element slots.

5bcf5a59c41e19 Bob Pearson 2021-05-27 17 * Notes:
ae6e843fe08d0e Bob Pearson 2021-09-14 18 * - The driver indices are always masked off to q->index_mask
5bcf5a59c41e19 Bob Pearson 2021-05-27 19 * before storing so do not need to be checked on reads.
ae6e843fe08d0e Bob Pearson 2021-09-14 20 * - The user whether user space or kernel is generally
ae6e843fe08d0e Bob Pearson 2021-09-14 21 * not trusted so its parameters are masked to make sure
ae6e843fe08d0e Bob Pearson 2021-09-14 22 * they do not access the queue out of bounds on reads.
ae6e843fe08d0e Bob Pearson 2021-09-14 23 * - The driver indices for queues must not be written
ae6e843fe08d0e Bob Pearson 2021-09-14 24 * by user so a local copy is used and a shared copy is
ae6e843fe08d0e Bob Pearson 2021-09-14 25 * stored when the local copy is changed.
5bcf5a59c41e19 Bob Pearson 2021-05-27 26 * - By passing the type in the parameter list separate from q
5bcf5a59c41e19 Bob Pearson 2021-05-27 27 * the compiler can eliminate the switch statement when the
ae6e843fe08d0e Bob Pearson 2021-09-14 28 * actual queue type is known when the function is called at
ae6e843fe08d0e Bob Pearson 2021-09-14 29 * compile time.
ae6e843fe08d0e Bob Pearson 2021-09-14 30 * - These queues are lock free. The user and driver must protect
ae6e843fe08d0e Bob Pearson 2021-09-14 31 * changes to their end of the queues with locks if more than one
ae6e843fe08d0e Bob Pearson 2021-09-14 32 * CPU can be accessing it at the same time.
