This message is most likely just a result of the VDOA not supporting the selected capture format. In vdoa_context_configure, you can see that the VDOA only writes YUYV or NV12. > (imx6, running linux 4.14-rc3, imx-vdoa is probed and never removed, > a dev_info "probed" would maybe be useful for others too?) > > It supsequently fails with > > cma: cma_alloc: alloc failed, req-size: 178 pages, ret: -12 That is -ENOMEM. Is CMA enabled and sufficiently large? For example, CONFIG_CMA=y CONFIG_CMA_DEBUGFS=y CONFIG_DMA_CMA=y CONFIG_CMA_SIZE_MBYTES=256 CONFIG_CMA_SIZE_SEL_MBYTES=y > which may or may not be related to having the vdoa (is it?), but > shouldn't the VDOA module be active by default? > > # cat /sys/module/coda/parameters/disable_vdoa > 0 I think it is not related to VDOA at all. Yes, by default the VDOA should be activated automatically for any supported format. regards Philipp
