The feature of control element set has been abandoned for a long time since firstly introduced in 2003. Furthermore, there's few applications to utilize this feature. These situations bring a hard work to persons who need the feature. Especially, a lack of test program make it harder to fix much bugs in this feature. This commit adds a test program as a sample of the feature. This program adds element sets of each element type to 'hw:0' in this order; boolean, integer, enumerated, bytes, IEC958 and integer64. Each iteration includes below scheme: 1. add an element set with 900 elements. Each of them has maximum number of members allowed by ALSA ctl core. 2. check all of events generated by above operation. 3. retrieve information of each element, then validate it. 4. unlock each member of all elements because they're initially locked. 5. write to all of members in all elements and read. 6. check all of events generated by above operation. 7. write information for threshold level to the element set and read it. 8. check all of events generated by above operation. 9. remove the element set. 10.check all of events generated by above operation. When any of these operations fail, it means regression occurs. Then, added elements still remain in a certain sound card. In this case, unloading drivers corresponding to the card is an easy way to recover. Besides, this program doesn't perform below element operations of ALSA ctl feature: - list - lock - replace Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de> |
