vga_switcheroo: Don't require handler init callback

2012-08-17T21:34:41Z

This callback is a no-op in nouveau, and the upcoming apple-gmux switcheroo support won't require it either. Rather than forcing drivers to stub it out, just make it optional and remove the callback from nouveau. Signed-off-by: Seth Forshee Signed-off-by: Matthew Garrett

vga_switcheroo: Remove assumptions about registration/unregistration ordering

2012-08-17T21:34:41Z

vga_switcheroo assumes that the handler will be registered before the last client, otherwise switching will not be enabled. Likewise it's assumed that the handler will not be unregistered without at least one client also being unregistered, otherwise switching will remain enabled despite no longer having a handler. These assumptions cannot be enforced if the handler is in a separate driver from both clients, as with the gmux found in Apple laptops. Remove this assumption.

vga_switcheroo: Enable/disable audio clients at the right time

2012-06-09T10:14:43Z

The audio clients have to be disabled before disabling the VGA and switching. Similarly, enabling the audio client should be done at last. Otherwise the audio-side operation stalls, eventually leading to Oops or lockups. Tested-by: Jörg-Volker Peetz Acked-by: Dave Airlie Signed-off-by: Takashi Iwai

vga_switcheroo: Add a helper function to get the client state

2012-06-08T09:24:12Z

Add vga_switcheroo_get_client_state() to get the current state of the client. This is necessary to determine the proper initial state of audio clients in HD-audio driver. Acked-by: Dave Airlie Signed-off-by: Takashi Iwai

vga_switcheroo: Add the support for audio clients

2012-05-13T09:27:21Z

Add the support for audio clients to VGA-switcheroo for handling the HDMI audio controller together with VGA switching. The id of the audio controller should be given explicitly at registration time unlike the video controller. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=43155 Signed-off-by: Takashi Iwai

vga_switcheroo: Introduce struct vga_switcheroo_client_ops

2012-05-13T09:24:09Z

This changes the API as a clean-up. Instead of passing multiple function pointers at each time, introduce a new struct holding the whole callback functions and pass it to the registration. The same struct will be used for the upcoming audio client registration, too. Signed-off-by: Takashi Iwai

vga_switcheroo: Refactor using linked list

2012-05-13T09:21:56Z

Refactor the code base a bit for the further work to adapt more clients. Signed-off-by: Takashi Iwai

vga: fix build when fbdev is a module

2012-04-24T08:50:21Z

This fixes the build breakage reported by Stephen in -next when merging the drm-next tree. Signed-off-by: Dave Airlie

vga-switcheroo: select VGA arbitration.

2012-04-24T08:50:19Z

Since Matthew's changes we have to select arbitration. Reported-by: devh on #radeon Signed-off-by: Dave Airlie

vga-switcheroo: Use vga_default_device()

2012-04-24T08:50:16Z

vga-switcheroo currently changes the default VGA device by fiddling with the IORESOURCE_ROM_SHADOW flag on the device. This isn't strictly accurate, since there's no guarantee that switching also changes the ROM decoding. Switch over to using the vgaarb functions for this.
