This is the method used to override LVDS in intel_lvds and appears to be an effective way to ensure that the driver does not enable VGA hotplug. This is the same patch from 2.6.32 kernel in R12 but ported to 2.6.38, will send upstream next.

Run the following command as root, specifically looking at bit 9: mmio_read32 $[$(pci_read32 0 2 0 0x10) + 0x61110] = 0x00000000 Change-Id: Id8240f9fb31d058d8d79ee72f7b4615c43893f5a Reviewed-on: http://gerrit.chromium.org/gerrit/1390 Reviewed-by: Olof Johansson <olofj@chromium.org> Tested-by: Duncan Laurie <dlaurie@chromium.org> Signed-off-by: Keith Packard <keithp@keithp.com> |
