Functions
static bool	ipc_server_client_is_input_blocked (volatile struct ipc_client_state *ics, enum xrt_input_name name)
	Is the given input blocked for this client by its ipc_client_io_blocks.
static void	ipc_server_client_filter_blocked_inputs (volatile struct ipc_client_state *ics, struct xrt_input *inputs, uint32_t input_count)
	Zero out the inputs that are blocked for this client, in place.
static void	ipc_server_client_filter_blocked_outputs (volatile struct ipc_client_state *ics, struct xrt_output *outputs, uint32_t output_count)
	Zero out the outputs if outputs are blocked for this client, in place.
static xrt_result_t	ipc_server_validate_output_value (volatile struct ipc_client_state *ics, const struct xrt_output_value *value)
	Plain output calls copy the value as is, so reject PCM values: they hold client pointers and must go through a varlen haptic output call.
static xrt_result_t	ipc_server_validate_pcm_haptic_buffer (volatile struct ipc_client_state *ics, const struct ipc_pcm_haptic_buffer *buffer)
	Reject haptic output calls with no samples, since the message channel can't send zero bytes, or with more samples than the service will allocate, see IPC_MAX_PCM_HAPTIC_SAMPLES.
