Exa and dri

[Thomas Hellström]

Hi.

I have some questions about the interoperability between exa and dri:

1) Is the dri lock guaranteed to be held between prepare and subsequent 
execute calls? Otherwise one cannot assume single-threaded access to the 
2D engine.

2) The via driver has a drm memory manager for the frame-buffer. 
Currently it gets all framebuffer memory
except screen, cursor, virtual queue and pixmap cache at startup. Having 
the memory manager discussion in mind, Would it be possible to hand all 
memory to the drm memory manager and make Exa call that one through the 
driver when dri is present?  Performance implications?
