at levels 5 (sound) and 6 (via1) on the Q700. Raise splhigh when reading and writing registers. It's ugly, but it's possible that we could get an interrupt from a higher-level source, causing a re-read of a memory location. This is not good when, e.g., we are reading the interrupt register. Ideally, we would just raise splhigh() in ncr53c9x_readregs(), but that's m.i. code, and it may be expensive on other architectures. |
