[Xen-devel] ATI fglrx OpenGL working in Xen!

[Jacob Gorm Hansen <jacobg@xxxxxxx>]

hi,

I gave the closed-source fglrx-driver another try, and with the latest 
xeno-unstable and some patching of the open-source wrapper provided with 
fglrx, I managed to get my ATI Radeon 9600SE accellerated OpenGL running 
at what appears to be full speed, in dom0.
I have attached diffs to the two source files that need changing, below. 
Basically, I replaced all CONFIG_X86* ifdefs with CONFIG_XEN*, and I 
replaced the calls to remap_page_range() with calls to 
io_remap_page_range().
This is not a very clean or nice patch, but it does the job. Does anyone 
 know where to send fglrx-patches, once I have a nicer version?
Jacob
