Hello I am developing a driver for a camera that supports read/write and mmap access to the buffers. When I am running the compliance test, I cannot pass it because of this test on v4l2-test-formats.cpp 904 if (!(node->caps & V4L2_CAP_READWRITE)) 905 fail_on_test(cap->readbuffers); 906 else if (node->caps & V4L2_CAP_STREAMING) 907 fail_on_test(!cap->readbuffers); What should be the value of cap-readbuffers for a driver such as mine, that supports cap_readwrite and cap_streaming? Or I cannot support both, although at least this drivers do the same? $ git grep CAP_READWRITE * | grep CAP_STREAMING pci/cx25821/cx25821-video.c: V4L2_CAP_READWRITE | V4L2_CAP_STREAMING; pci/cx88/cx88-video.c: cap->device_caps = V4L2_CAP_READWRITE | V4L2_CAP_STREAMING; pci/saa7134/saa7134-video.c: cap->device_caps = V4L2_CAP_READWRITE | V4L2_CAP_STREAMING; platform/marvell-ccic/mcam-core.c: V4L2_CAP_READWRITE | V4L2_CAP_STREAMING; platform/via-camera.c: V4L2_CAP_READWRITE | V4L2_CAP_STREAMING; usb/cx231xx/cx231xx-video.c: cap->device_caps = V4L2_CAP_READWRITE | V4L2_CAP_STREAMING; usb/em28xx/em28xx-video.c: V4L2_CAP_READWRITE | V4L2_CAP_VIDEO_CAPTURE | V4L2_CAP_STREAMING; usb/stkwebcam/stk-webcam.c: | V4L2_CAP_READWRITE | V4L2_CAP_STREAMING; usb/tlg2300/pd-video.c: V4L2_CAP_STREAMING | V4L2_CAP_READWRITE; Thanks! -- Ricardo Ribalda -- 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
