menuconfig RT_USING_DEVICE_IPC
bool "Using device drivers IPC"
default y
select RT_USING_MUTEX
select RT_USING_SEMAPHORE
help
Enable the device-layer IPC helpers (pipes, message queues, workqueues)
that many drivers rely on for buffering and deferred processing. Disable
only on extremely small systems that do not load drivers needing mutex or
semaphore-based IPC primitives.
if RT_USING_DEVICE_IPC
config RT_UNAMED_PIPE_NUMBER
int "The number of unamed pipe"
default 64
help
Maximum number of anonymous pipes that can be created at runtime.
Reduce this to save memory if your application uses few pipes.
config RT_USING_SYSTEM_WORKQUEUE
bool "Using system default workqueue"
default n
help
Create a global system workqueue thread so drivers can defer work out
of interrupt context without allocating their own threads.
if RT_USING_SYSTEM_WORKQUEUE
config RT_SYSTEM_WORKQUEUE_STACKSIZE
int "The stack size for system workqueue thread"
default 2048
help
Stack size in bytes for the common workqueue thread; increase when
queued jobs perform complex tasks or call into heavy subsystems.
config RT_SYSTEM_WORKQUEUE_PRIORITY
int "The priority level of system workqueue thread"
default 23
help
Scheduler priority assigned to the workqueue thread. Lower numbers
mean higher priority; adjust relative to other timing-sensitive
threads in your system.
