Hi Mark and Everyone,
Fix your mailer to word wrap at 80 columns, I've reflowed your text.
Sorry about that. The email client/server is too "smart." It is already set to 80 columns. Until I figure out a more permanent solution, I will add a [return] at the end of each line.
When a codec driver control handling function needs to write a group of registers without any other register of the same codec being written to in parallel by ALSA, what is the best way to do this under the snd-soc codec driver architecture? In the current architecture, does the driver's control handling function execute serially with other ALSA automated activities?
The framework should be taking care of locking for you in most situations. If you implement custom controls you will want to take the CODEC mutex while applying changes from them (most of the existing drivers are lax about this) and similarly for IRQs.
Ok thanks!
