What could cause a DMA transfer to a page with physical address below
64mb to fail ?
Context: I am using rvmalloc code from bt848 driver in video capture
module (km, http://www.sf.net/projects/gatos). The device that does the
transfer is Radeon AIW AGP, transfer from device to main memory.
Hi folks,
I'm back in my mission to slowly add DRI support for my platform.
I'd like to start by just getting a basic /dev/agpgart working.
It SEEMS like a simple tast.
Trouble is, I cant find anything that will USE it.
Xfree3.3.6 does not seem to use it at all.
Xfree.4.1.0 has SOME code that

Hello
Have you checked that your AGP module is correctly loaded ?
If so, I suggest that you compile and run (as root, and before running X) the
C program located at :
http://ltswww.epfl.ch/~aspert/patches/testgart.c
Send the output of the program to the list...
Best regards
Nicolas.

On a different topic - Michel, do you know how DRI gets it's DMA able
memory, from agpgart or not ? - Thanks !
From the DRM. It can use both AGP and PCI GART but that's not
transparent at the DRM level.

And DRM gets it from agpgart, right ?
For AGP GART, yes. PCI GART it does on its own.
Thanks, that's what I needed to know. One last question - would you know
whether Radeon AGP has a restriction of not being able to DMA into non-AGP
memory ? I am providing a table with physical

Hi, I am the maintainer of V4L capture module for All-in-Wonder cards.
I need some help figuring out how to interface with drm.
The problem: the module works fine, except that (at least Radeons) want
physical memory from AGP addressable range. So I can either write my own
memory allocation
Sorry if this is a duplicate: It's been 8 hours or more, and I havent seen
a copy of my email to the list.
I'm looking to write a driver that implements /dev/agpgart, as a first step
towards doing a full DRI port.
Trouble is, I cant seem to find anything that USES the device any more.
In Xfree

2. I notice that both r128 and radeon do not make
a map for texture in PCI/PCIGART mode. Is it ok?
I guess texturing via the PCI bus wouldn't be much of a performance
gain, if any, so it makes sense.
In addition, although 32-bit mode
