The VPU then returns the size of the -parameter that it wished to return, and as much as possible of -that parameter is returned to the client. - -The implementation previously only returned the size provided -by the VPU should it exceed the buffer size. So for parameters -such as the supported encodings list the client had no idea -how much of the provided storage had been populated. - -Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org> ---- - drivers/staging/vc04_services/vchiq-mmal/mmal-vchiq.c | 3 ++- - 1 file changed, 2 insertions(+), 1 deletion(-) - ---- a/drivers/staging/vc04_services/vchiq-mmal/mmal-vchiq.c -+++ b/drivers/staging/vc04_services/vchiq-mmal/mmal-vchiq.c -@@ -1412,11 +1412,12 @@ static int port_parameter_get(struct vch - */ - memcpy(value, &rmsg->u.port_parameter_get_reply.value, - *value_size); -- *value_size = rmsg->u.port_parameter_get_reply.size; - } else { - memcpy(value, &rmsg->u.port_parameter_get_reply.value, - rmsg->u.port_parameter_get_reply.size); - } -+ /* Always report the size of the returned parameter to the caller */ -+ *value_size = rmsg->u.port_parameter_get_reply.size; - - pr_debug("%s:result:%d component:0x%x port:%d parameter:%d\n", __func__, - ret, port->component->handle, port->handle, parameter_id); |
