Hi Adam, Jesse, We here at SGI are getting ready to deploy the SGI Ultraviolet system (see refs below) and the question came up about supporting legacy I/O for multiple VGA cards. The UV architecture requires some additional setup when changing the "owner" of the legacy VGA I/O space.
I've been trying to follow the progress of the VGA Arbiter, and it's use by X, as a means of providing the kernel hook to execute this setup. Can you (or someone) enlighten me as to whether a.) X still requires the use of legacy I/O [or are all accesses being done with MMIO operations]? and b.) is the plan still to use the VGA Arbiter as currently implemented in linux-2.6.32? Some additional information... UV will not be supporting the external VGA cards as vgacons, strictly as X/OpenGL devices. There is one dedicated VGA for the system console. Currently planned releases: linux-2.6.32, X-7.4.1 Thanks!
