It is also the allocation size.

buffer_min

uint32_t rtems_bdbuf_config::buffer_min

Minimum buffer size.

max_read_ahead_blocks

uint32_t rtems_bdbuf_config::max_read_ahead_blocks

Number of blocks to read ahead.

max_write_blocks

uint32_t rtems_bdbuf_config::max_write_blocks

Number of blocks to write at once.

read_ahead_priority

rtems_task_priority rtems_bdbuf_config::read_ahead_priority

Priority of the read-ahead task.

swap_block_hold

uint32_t rtems_bdbuf_config::swap_block_hold

Period a buffer is held.

swapout_period

uint32_t rtems_bdbuf_config::swapout_period

Period swap-out checks buf timers.

swapout_priority

rtems_task_priority rtems_bdbuf_config::swapout_priority

Priority of the swap out task.

swapout_worker_priority

rtems_task_priority rtems_bdbuf_config::swapout_worker_priority

Priority of the swap out task.

swapout_workers

size_t rtems_bdbuf_config::swapout_workers

The number of worker threads for the swap-out task.

task_stack_size

size_t rtems_bdbuf_config::task_stack_size
