History
Michael Sevakis 36480c259f Fix a race condition in as3525 I2C driver caused by stacked ISRs. 
It was possible for interrupts of higher priority than the current IRQ
level to attempt to restart the interface while it was still active on
a transfer. The list modification also wasn't protected within the I2C
ISR itself.

dbop-as3525.h Sansa AMS: Time has shown that switching between 16 and 32bit mode costs much time (due to the micro delay needed), so do 32bit transfers unconditionally for lcd updates at the cost of updating slightly larger rectangles (gives upto 15% speed up, nearly at maximum now). 2010-01-07 22:21:41 +00:00

dma-pl081.c Deal with a complication when transferring recording method from PP5024: since the FIFO POP is always read until empty, keep track of sample parity instead of always saving the first one in the FIFO upon entering the ISR or else the first of a duplicate that is also the last in the FIFO would get duplicated. Also, give top priority to audio interrupts in all cases. 2011-12-12 20:12:22 +00:00
