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.

---help---
Plug and Play (PnP) is a standard for peripherals which allows those
peripherals to be configured by software, e.g. assign IRQ's or other
parameters. No jumpers on the cards are needed, instead the values
are provided to the cards from the BIOS, from the operating system,
or using a user-space utility.
Say Y here if you would like Linux to configure your Plug and Play
devices. You should then also say Y to all of the protocols below.
Alternatively, you can say N here and configure your PnP devices
using user space utilities such as the isapnptools package.
If unsure, say Y.

bool "PNP debugging messages"
depends on PNP
help
Say Y here if you want the PNP layer to be able to produce debugging
messages if needed. The messages can be enabled at boot-time with
the pnp.debug kernel parameter.
This option allows you to save a bit of space if you do not want
the messages to even be built into the kernel.
If you have any doubts about this, say Y here.
