224MB for textures on Intel 950GM

Mon Sep 29 08:18:14 PDT 2008

Hello,

I'm developing a game with uses a lot of textures and something goes wrong with 224MB memory allocation for the intel 950GM using the driver i915.

I developed a tool to "compress" some textures and see the amount of memory used for my game.

On windows, with the Intel's driver, I can play my game that uses 180MB for textures, but this game doesn't work on the linux box, because is too slow.

I think there is a problem with the DVMT (Dynamic Virtual Memory Technology) on the linux. It seems that the linux box can only use 128MB of fixed Memory, and cannot use the 224 of Max memory. (BIOS set to DVMT 224MB)

I forced VideoRam to 229376 (224MB) on X.org but no luck.

¿I need to patch the kernel or activate some driver option, so I can use the 224MB of Shared video RAM?

I attached some information about my linux box.

I'm running a debian etch.

I apologized for my English.

Thank's
