Thank you for the report.

I've retested the HDMI output on Lager running v4.10-rc2 with=20
shmobile_defconfig using your test method (with the bmap application) a=
nd I=20
haven't been to reproduce the problem. I have also tested v4.8 and v4.9=
, and=20
both worked fine as well.

The kernel was started with the HDMI cable unplugged in all tests. If I=
 boot=20
the board with the cable plugged in, framebuffer allocation fails due t=
o CMA=20
being disabled. Enabling CMA makes the test pass on all three kernels, =
both=20
with the HDMI cable plugged at boot and plugged after boot.

If you can still reproduce the problem on your side, could you please p=
rovide=20
me with a very detailed test procedure (including the kernel .config an=
d any=20
test application or data you're using) ?

--=20
