Hi, Mitch,
I know your Error key point, because it couldn't allocate the shadow
memory for rotation after crtc_shadow_allocate.
In our xf86-video-geode driver, all of memories are allocated by
GeodeAllocOffscreen, the exa offscreen memory is part of the memorySize. And
the rotation data is not in memorySize, it is allocated after memorySize.
You can check your Xorg.0.log file about "Gedoe LX video memory" and
"LX video memory", because the shadow buffer (rotate memory) will be allocated
from "FREE memory", if only 0x0 bytes are available, it can not do the rotate
operation.
Thanks,
Hunk Cui

Hi Hunk,
Thanks for the patch. I have tried it out with Xorg server 1.7.5, but
it doesn't work.
$ xrandr -q | grep connected
default connected 1024x768+0+0 (normal left inverted right x axis y
axis) 0mm x 0mm
So I will use "default".
$ xrandr --output default --rotate left
xrandr: Configure crtc 0 failed
The screen goes black for a moment, then comes back just as before,
i.e., not inverted. This happens for "left", "right", and "inverted".
There is no flash for "normal", and it returns immediately.
This is the same with the add/subtract lx_crtc->rotate_mem->size, and
with the add/subtract 1.
This message appears in the X log:
(EE) GEODE(0): Couldn't allocate the shadow memory for rotation
(EE) GEODE(0): You need 0x300000 bytes, but only 0x0 bytes are available
Is this because I am using Xorg server 1.7.5? Do you think it would
work with 1.8? Is there something I'm doing wrong?
I will try 1.8 now.
Thank you for your help!
Mitch.
