Revision 85a00d9bbfb4704fbf368944b1cb9fed8f1598c5 authored by Peter Jones on 22 September 2010, 20:05:04 UTC, committed by Linus Torvalds on 23 September 2010, 00:22:39 UTC
Some Apple machines have identical DMI data but different memory configurations for the video. Given that, check that the address in our table is actually within the range of a PCI BAR on a VGA device in the machine. This also fixes up the return value from set_system(), which has always been wrong, but never resulted in bad behavior since there's only ever been one matching entry in the dmi table. The patch 1) stops people's machines from crashing when we get their display wrong, which seems to be unfortunately inevitable, 2) allows us to support identical dmi data with differing video memory configurations This also adds me as the efifb maintainer, since I've effectively been acting as such for quite some time.

This option enables basic support for the SGI IOC3-based Base IO
controller card. This option does not enable any specific
functions on such a card, but provides necessary infrastructure
for other drivers to utilize.
If you have an SGI Altix with an IOC3-based
I/O controller or a PCI IOC3 serial card say Y.
Otherwise say N.
