Thank you for the report. I've retested the HDMI output on Lager running v4.10-rc2 with shmobile_defconfig using your test method (with the bmap application) and I haven't been to reproduce the problem. I have also tested v4.8 and v4.9, and both worked fine as well. The kernel was started with the HDMI cable unplugged in all tests. If I boot the board with the cable plugged in, framebuffer allocation fails due to CMA being disabled. Enabling CMA makes the test pass on all three kernels, both with the HDMI cable plugged at boot and plugged after boot. If you can still reproduce the problem on your side, could you please provide me with a very detailed test procedure (including the kernel .config and any test application or data you're using) ? -- Regards, Laurent Pinchart
