[openchrome-users] xf86-video-openchrome: X server crashing right upon start after upgrade to 1.20.11

[Kevin Brace]

Hi Peter,

Sorry for not responding right away.
Since you mentioned X Server Version 1.20.11, I did test the current code (Version 0.6.400) with it on Gentoo Linux, and it worked fine.
If I were to guess the issue, it might be due to a rootless X Server issue.
For OpenChrome DDX to function properly, you will need root privilege.
    Also, try blacklisting FBDEV related modules.

> After upgrading to 1.20.11 the X server crashes / dumps core right after its launch here. The last log messages before the crash are
>   Mapping MMIO at <some address>
>   Unable to map MMIO. Error: Permission denied

> Seen using the latest commits of branches master or main (main patched to have it find drm.h, see [1]), Arch Linux x86_64, VN896 / Chrome 9 HC. Sticking with point release 10 isn't really an option as 11 is fixing a vulnerability [2].
