6.12-stable review patch. If anyone has any objections, please let me know.
From: Thomas Zimmermann tzimmermann@suse.de
commit 6f719373b943a955fee6fc2012aed207b65e2854 upstream.
Blank the display by disabling sync pulses with VGACR17<7>. Unblank by reenabling them. This VGA setting should be supported by all Aspeed hardware.
This patch breaks VGA output on my machine. I have already reported this regression against mainline 6.18-rc2, see here:
https://lore.kernel.org/all/a40caf8e-58ad-4f9c-af7f-54f6f69c29bb@googlemail....
When I revert this patch from 6.12.55-rc1, the issue goes away, just as in mainline. I'm still going to test 6.17.5-rc1 too and report back, but I guess it will be just the same.
Now dropped from this queue as well. I'll go push out a -rc2 to be safe.
thanks,
