From: Alan Cox <[email protected]> The ivtv stream buffers may be for receive or for send but the attached sg handle is always destined cpu->device. We flush it correctly but the allocation is wrongly done with the same type as the buffers.
See bug: http://bugzilla.kernel.org/show_bug.cgi?id=13385 (Note this doesn't close the bug - it fixes the ivtv part and in turn the logging next shows up some rather alarming DMA sg list warnings in libata) Signed-off-by: Alan Cox <[email protected]> --- drivers/media/video/ivtv/ivtv-queue.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/drivers/media/video/ivtv/ivtv-queue.c b/drivers/media/video/ivtv/ivtv-queue.c index ff7b7de..7fde36e 100644 --- a/drivers/media/video/ivtv/ivtv-queue.c +++ b/drivers/media/video/ivtv/ivtv-queue.c @@ -230,7 +230,8 @@ int ivtv_stream_alloc(struct ivtv_stream *s) return -ENOMEM; } if (ivtv_might_use_dma(s)) { - s->sg_handle = pci_map_single(itv->pdev, s->sg_dma, sizeof(struct ivtv_sg_element), s->dma); + s->sg_handle = pci_map_single(itv->pdev, s->sg_dma, + sizeof(struct ivtv_sg_element), PCI_DMA_TODEVICE); ivtv_stream_sync_for_cpu(s); } -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
