THANKS You're welcome. You have yourself to thank for too because if it wasn't your shown interest and your keen debugging of that kernel issue this day would happen much later! /Tony Regards, Jose Fonseca ___ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel

I assumed it was an abstraction layer, but after googling around I saw it's not. (I confess I was rather naive in this issue as a GART allows to make a disperse segments of physical memory as a single contiguous memory for the cards - there had to be hw support in some end for this to happen...) I'm already working on the subject. I'm basing on the work of the gamma driver, which is, as far as I can tell, the only existing DRI driver which has non-GART PCI support, and it seems that there is no scatter/gather memory allocation (which makes the whole process even simpler). Note that this doesn't prevent people from testing DRI on mach64 PCI cards. I'm still waiting for some feedback... or I'll start focusing on other things! :) BTW Leif, how are going the glean tests of mach64? I noticed you commited a patch, but I ran glean on mach64 and there still are a bunch of errors in blendFunc and logicOp. Since you're more in the subject could you give me a brief update of the remaining problems and what may be causing them so I can help?

From memory, the only difference between AGP and PCI DMA scatter-gather tables is you need to set a bit somewhere to specify the pages are AGP memory, when required. Other than that, the DMA mechanism is the same, from the driver's point of view. As far as I can remember, anyway :-) -- Gareth ___ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
[Dri-devel] Mach64 PCI support added to 2D driver
I've just commited support for PCI only Mach64 cards to the 2D driver. It should recognize a PCI card and allocate memory from the PCIGART. There is still missing support for PCI operation of an AGP card when agpgart isn't available - not much really - just a question of book-keeping so it will be done shortly. I'm still not sure if everything is in place for DRI on Mach64 PCI cards. I'm in the process of updating and recompiling the kernel to have agpgart as a module to be able to check it myself.
