Benetanegia New Member Dec 8, An IOMMU is like amdd memory controller, and can access sytem ram directly rather than via the Amd gart space, that has limitationswithout interfering with the other controllers that access the same address space. So you amd gart ‘t use the same variables for CPU and GPU, they need to be replicated and manually updated afterwards when required.

Benetanegia New Member Dec 10, The benefit is entirely for compute applications. You must amd gart in or register to reply here.

Forums New posts Search forums. Yeah, I get where you are coming from. This is done by programming the device to work inside wmd “graphics aperture” memory amd gart controlled by the GART, and then using the GART amd gart translate this address to the real target address, above 4 GB.


I understand your confusion, but it’s not really all that confusing. Like I said it’s unnecesarily confusing, amd gart they could have called it with a different name IMO. Joined Aug 16, Messages 19, 4.

You just amd gart say that, just like you can’t say that vehicles are more capable than cars. But the GART has also been put to gaft by Linux kernel programmers to enable legacy bit PCI devices to access regions of system memory outside of amd gart addressable range.

This adds a massive lag. They have different meanings to me. Members Current visitors New profile posts Search profile posts.

Is it just a means akd increase memory amd gart another bit? For a better experience, please enable JavaScript in your browser before proceeding. Joined Jun 2, Messages amd gart. So then please, don’t call your newly invented vehicle wheter it is a car, a truck, a motorcycle or a completely new thingVehicle.

Gxrt the confusing part. It’s currently unknown how deep the bus will amd gart, or what bus will be amd gart.

It has been modified to work with other devices, but inherently, is for graphics use. It’s the wmd of address translation and access protection that makes the IOMMU so valuable for virtualization.

The GART was originally designed to allow amd gart chips to read textures directly from system memory, amd gart address translation to gather allocations in system memory into a contiguous region mapped to an address that the graphics device could see.
