waiti would cause FW panic if it is called in irq level higher than passive level Signed-off-by: Rander Wang <rander.wang@linux.intel.com>
The register status is checked by polling its value in request time Signed-off-by: Rander Wang <rander.wang@linux.intel.com>
It is caused by the change of removing dai waiting after stop. dma should not be stopped in dai_comp_trigger if HW LLI is not enable. At this time DMA is still working and it can't be stopped DMA engine would stop the channel automatically after each transfer. So just query channel status to stop dma on BYT Signed-off-by: Pan Xiuli <xiuli.pan@linux.intel.com> Signed-off-by: Rander Wang <rander.wang@linux.intel.com>
list_item_for_safe is safe for item deletion, but when a new item is appended to the list. It seems the item could not be go through. To fix this limitation, move interrupt clear to make sure every IRQ is handled. Do not try to handle two task with one IRQ handler. Signed-off-by: Pan Xiuli <xiuli.pan@linux.intel.com>
There will be new task added in schedule_edf function, refine the function to handle multiple task. Signed-off-by: Pan Xiuli <xiuli.pan@linux.intel.com>
