hi,
I just purchased an ATI Radeon 9600 128MB for use with my Xen testbox.
However, upon loading the intel-agp module, the following test fails:
in drivers/char/agp/backend.c:
if (bridge->driver->create_gatt_table()) {
printk(KERN_ERR PFX
"unable to get memory for graphics translation
table.\n");
rc = -ENOMEM;
goto err_out;
}
The card runs fine (i.e. accellerated) with vanilla linux 2.6.10.
Any suggestions?
Jacob

The chipset is an Intel 875. Jacob ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

(Whether or not the subsequent X crash has anything to do with this is not clear -- the ATI wrapper has quite a few references to virt_to_phys(), so likely some problems there as well.) Is there a good reason for this / what will it take to implement ioremap_nocache correctly?
