[Linux-fbdev-devel] Radeon AIW 8500DV support ?

[Yann D. <yd...@al...>]

Hi,

I just bought a 8500DV, and find out that the fb device does not know about
it yet.  I'd be happy to play with the driver and test stuff, but I lack
knowledge of the driver's architecture, and of the hardware...  Needless to
say, if you have any pointers that could help me much :)

I've looked at the driver code and have a couple of questions:

- I notice there is already a PCI id for 8500 (R200 chip), and the 8500DV
uses a different ID.  I suppose I should add it, but I'm wondering about the
naming conventions used for PCI_DEVICE_ID_RADEON_*  (I'd be tempted to use
DV, but well... :)

BTW, the device info is as follows, I suppose the ID to add is 4242 ?

- I'll suppose I'll have to add an entry to radeon_get_pllinfo() - what are
those pll fields, and how am I supposed to find out the values ?

- should there be any additional info to add, aside from this and the small
stuff in radeonfb_pci_register() ?

- the drm module appears to recognize the card (I still have to fetch
XFree86 4.2 to check whether this works) - is there any chance there is
any info to get from their implementation ?

# cat /proc/dri/0/name
radeon 0xe200
