Hi Mauro,
After merging the v4l-dvb tree, today's linux-next build (x86_64 allmodconfig) failed like this:
ERROR: "dma_common_get_sgtable" [drivers/media/v4l2-core/videobuf2-dma-contig.ko] undefined!
Caused by commit 9ef2cbeb8192 ("[media] v4l: vb2-dma-contig: add support for DMABUF exporting"). dma_common_get_sgtable() is called from the inline dma_get_sgtable_attrs() and dma_get_sgtable_attrs() is "called from" dma_get_sgtable(). dma_common_get_sgtable() is only defined if ARCH_HAS_DMA_DECLARE_COHERENT_MEMORY is set which depends on CONFIG_HAVE_GENERIC_DMA_COHERENT being set which it isn't for this build.
I have used the v4l-dvb tree form next-20121026 for today.
Please try testing your tree with an x86_64 allmodconfig build. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au [unhandled content-type:application/pgp-signature] | |
