[Dri-devel] bus master on apm suspend/resume for r128 mobility

[Jeremy K. <ka...@li...>]

First off, I have to applaud the efforts that have gone into the DRI
thus far;  I now have working 3D on my laptop with a Rage 128 Mobility
M3.  Unfortunately, after an APM suspend/resume cycle, the BIOS resets
the video chip to the non bus master mode and a restart of X (or calling
setpci) is required for DRI to work again.  Are there any hooks in the
drivers which get called on suspend and resume that could be used to
reenable bus mastering on apm resume?  If not, perhaps enabling the bus
mastering at another point during the initialization (and I don't even
close to know enough about the architecture of the DRI drivers to
suggest where)?

Thanks!
