      apple-gmux: lock iGP IO to protect from vgaarb changes · 4eebd5a4
      Bruno Prémont authored
      As GMUX depends on IO for iGP to be enabled and active, lock the IO at
      vgaarb level. This should prevent GPU driver for dGPU to disable IO for
      iGP while it tries to own legacy VGA IO.
      
      This fixes usage of backlight control combined with closed nvidia
      driver on some Apple dual-GPU (intel/nvidia) systems.
      
      On those systems loading nvidia driver disables intel IO decoding,
      disabling the gmux backlight controls as a side effect.
      Prior to commits moving boot_vga from (optional) efifb to less optional
      vgaarb this mis-behavior could be avoided by using right kernel config
      (efifb enabled but vgaarb disabled).
      
      This patch explicitly does not try to trigger vgaarb changes in order
      to avoid confusing already running graphics drivers. If IO has been
      mis-configured by vgaarb gmux will thus fail to probe.
      It is expected to load/probe gmux prior to graphics drivers.
      
      Fixes: ce027dac # nvidia interaction

      .. after extensive statistical analysis of my G+ polling, I've come to
      the inescapable conclusion that internet polls are bad.
      
      Big surprise.
      
      But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38%
      margin, in a poll that people weren't even supposed to participate in.
      Who can argue with solid numbers like that? 5,796 votes from people who
      can't even follow the most basic directions?
      
      In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%,
      but with a total of 29,110 votes right now.
      
      Now, arguably, that vote spread is only about 3,200 votes, which is less
      than the almost six thousand votes that the "please ignore" poll got, so
      it could be considered noise.
      
      But hey, I asked, so I'll honor the votes.
