The pa_timer has also been modified to be per adapter. The timer is now stopped when the queue is empty. The bcast_pa_requests queue, along with the pa_timer_id are now stored in the bap_data structure. Each adapter already has a coresponding entry in the sessions queue. Operations on the old bcast_pa_requests have been modified to be made on the appropriate bap_data entry. The bap_bcast_remove function has also been updated to remove from the queue entries of devices that were freed. --- profiles/audio/bap.c | 109 +++++++++++++++++++++++++++++++------------ 1 file changed, 79 insertions(+), 30 deletions(-) diff --git a/profiles/audio/bap.c b/profiles/audio/bap.c index db0af7e7c..82c6cf313 100644 --- a/profiles/audio/bap.c +++ b/profiles/audio/bap.c @@ -107,6 +107,8 @@ struct bap_data { struct queue *snks; struct queue *bcast; struct queue *streams; + struct queue *bcast_pa_requests; + unsigned int pa_timer_id; GIOChannel *listen_io; int selecting; void *user_data; @@ -127,8 +129,6 @@ struct bap_bcast_pa_req { }; static struct queue *sessions; -static struct queue *bcast_pa_requests; -static unsigned int pa_timer_id; /* Structure holding the parameters for Periodic Advertisement create sync. * The full QOS is populated at the time the user selects and endpoint and @@ -965,15 +965,25 @@ static DBusMessage *set_configuration(DBusConnection *conn, DBusMessage *msg, return NULL; } +static bool match_adapter_entry(const void *data, const void *match_data) +{ + const struct bap_data *bdata = data; + const struct btd_adapter *adapter = match_data; + + return (bdata->user_data == adapter) && (bdata->device == NULL); +} + static void iso_bcast_confirm_cb(GIOChannel *io, GError *err, void *user_data) { struct bap_bcast_pa_req *req = user_data; struct bap_setup *setup = req->data.setup; + struct bap_data *bap_data = queue_find(sessions, + match_adapter_entry, setup->ep->data->adapter); int fd; DBG("BIG Sync completed"); - queue_remove(bcast_pa_requests, req); + queue_remove(bap_data->bcast_pa_requests, req); /* This device is no longer needed */ btd_service_connecting_complete(setup->ep->data->service, 0); @@ -1109,6 +1119,7 @@ static void iso_pa_sync_confirm_cb(GIOChannel *io, void *user_data) GError *err = NULL; struct bap_bcast_pa_req *pa_req = user_data; struct bap_data *data = btd_service_get_user_data(pa_req->data.service); + struct bt_bap *bap = data->bap; struct bt_iso_base base; struct bt_iso_qos qos; @@ -1130,12 +1141,13 @@ static void iso_pa_sync_confirm_cb(GIOChannel *io, void *user_data) g_io_channel_unref(data->listen_io); g_io_channel_shutdown(io, TRUE, NULL); data->listen_io = NULL; - queue_remove(bcast_pa_requests, pa_req); + data = queue_find(sessions, match_adapter_entry, data->adapter); + queue_remove(data->bcast_pa_requests, pa_req); /* Analyze received BASE data and create remote media endpoints for each * BIS matching our capabilities */ - parse_base(data->bap, &base, bap_debug); + parse_base(bap, &base, bap_debug); } static bool match_data_bap_data(const void *data, const void *match_data) @@ -2015,25 +2027,37 @@ static void pa_and_big_sync(struct bap_bcast_pa_req *req); static gboolean pa_idle_timer(gpointer user_data) { - struct bap_bcast_pa_req *req = user_data; + struct bap_data *bap_data = user_data; + struct bap_bcast_pa_req *req = + queue_peek_head(bap_data->bcast_pa_requests); bool in_progress = FALSE; + /* If the queue is empty, stop the timer.
