Hi there, I am working on the drm code in the drm-tracking branch. I want to avoid the waits in the ioctl, by using the command queue interrupt. In the spec I have seen four interrupt related registers. I also saw that the mci module writes into the clear register to "ack the interrupt source". Is this special to the MMC interrupt? When do I need to "set" or "enable" the command queue interrupt? Lars-Peter Clausen already told me that I need to enable the interrupt after it triggered once. What else is there to consider?
kind regards Andreas Pokorny
