However, that configuration in v4.8 doesn't enable CONFIG_CMA, which causes at least the DU driver to fail probing the device. I thus assume you have modified the configuration to enable CMA. The fact that shmobile_defconfig doesn't include the uvcvideo driver used by test 14 seems to confirm local modifications to the configuration. It would be useful to attach the kernel .config file to future reports to help reproducing the test failures with the exact same configuration. By the way, while at it, your e-mails are filtered out by the vger.kernel.org server as they contain HTML. If you could send future reports without HTML it would help them reaching the mailing list archive (although the presence of an attachment might not be appreciated by vger.kernel.org, I'm not sure about that). > So we would like to report the summary of the failure. Issue 8 ("Lager: bad image quality when shown on HDMI display") can't be reproduced on my system when displaying a test pattern with the modetest application. Could you please share more information on how to reproduce the problem ? Issue 11 ("VSP1:error message appears on initilization") has been introduced in commit 94fcdf829793b141dc93e20a2bbd9eeaa44ea25f Author: Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx> Date: Thu Feb 11 22:49:14 2016 -0200 [media] v4l: vsp1: Add FCP support and fixed in commit fd44aa9a254b18176ec3792a18e7de6977030ca8 Author: Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx> Date: Wed Aug 17 09:57:37 2016 -0300 [media] v4l: rcar-fcp: Don't force users to check for disabled FCP support The fix is available in v4.9-rc1. I've also submitted it for inclusion in the v4.8 stable series. Issue 14 ("USB-CAM: Warning message appears if remove the usb-camera cable under using") is likely not a Renesas-specific problem, but as I'm the maintainer of the uvcvideo webcam driver you used for testing I'll investigate that. -- Regards, Laurent Pinchart
