vga_switcheroo: don't toggle-switch devices

2011-05-15T22:57:04+00:00

If the requested device is already active, ignore the request.

This restores the original behaviour of the interface. The change was
probably an unintended side effect of

commit 66b37c6777c4 vga_switcheroo: split switching into two stages

which did not take into account to duplicate the !active check in the split-off
stage2.

Fix this by factoring that check out of stage1 into the debugfs_write routine.

drm/i915: Recognise non-VGA display devices

2011-01-23T12:52:16+00:00

Starting with SandyBridge (though possible with earlier hacked BIOSes),
the BIOS may initialise the IGFX as secondary to a discrete GPU. Prior,
it would simply disable the integrated GPU. So we adjust our PCI class
mask to match any DISPLAY_CLASS device.

In such a configuration, the IGFX is not a primary VGA controller and
so should not take part in VGA arbitration, and the error return from
vga_client_register() is expected.

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

2011-01-21T01:02:05+00:00

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

vga_switcheroo: comparing too few characters in strncmp()

2011-01-07T05:29:37+00:00

This is a copy-and-paste bug.  We should be comparing 4 characters here
instead of 3.

vga_switcheroo: add reprobe hook for fbcon to recheck connected outputs.

2011-01-05T03:44:07+00:00

This adds a hook after the mux is switched for the driver to reprobe
the connected outputs.

vga_switcheroo: add debugging mux switch option.

2011-01-05T03:43:15+00:00

This allows the mux to be switched from userspace using MIGD/MDIS
command to the switch.

vga_switcheroo: make power switch handler optional

2011-01-05T03:43:05+00:00

At least on the nvidia mux the power switch seems to be executed
by the ACPI PS0/PS3 methods so need to do it explicitly.
