Well, surprise surprise with the YUV422P format. We're not done yet ... There is a little issue with overrun : buf->active_dma is cleared in dma irq handler (for example suppose is cleared of DMA_U which finished first). Then an overrun occurs, and we restart that frame ... We should have reset buf->active_dma to DMA_Y | DMA_U | DMA_V. I think same thing applies to the "hot chain" link miss restart. The non-regression tests are not yet finished ... exciting, isn't it ? :) Cheers. -- Robert -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
