[PATCH] drm/mgag200: Flag all G200 SE A machines as broken wrt <startadd>

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Several MGA G200 SE machines don't respect the value of the startadd
register field. After more feedback on affected machines, neither PCI
subvendor ID nor the internal ID seem to hint towards the bug. All
affected machines have a PCI ID of 0x0522 (i.e., G200 SE A). It was
decided to flag all G200 SE A machines as broken.
