bunnie	b596c40dd6	refactor I2C to have work queue, cleaner (but untested) APIs	2021-05-06 03:40:04 +08:00
bunnie	bb5bc1d212	refactor i2c to break out the i2c machine to a separate server ... the concurrency issues on I2C are getting hairy, and it was probably a dubious decision from the start to merge I2C into the LLIO block; but originally this was motivated by the idea of keeping all the "miscellaneous slow stuff" in one process to keep the memory footprint small and make code a bit more readable. Keeping I2C in the same process space as the LLIO but splitting it into its own thread and server splits the difference, by giving us more options to deal with the concurrency, without inflating the size of the kernel binary and allocating a lot of extra static data.	2021-05-06 00:45:14 +08:00

bunnie	50174f99e5	re-org the codec crate so that it can accommodate gnarly backends ... This is in anticipation of: 1) supply chain issues causing CODEC chips to change out 2) host integration being a PITA	2021-05-03 00:31:05 +08:00
