vga_switcheroo.h: fix pci_dev warning

2012-06-16T10:11:25Z

Fix warnings on some architectures/configs (not on x86): include/linux/vga_switcheroo.h:28:30: warning: 'struct pci_dev' declared inside parameter list [enabled by default] include/linux/vga_switcheroo.h:28:30: warning: its scope is only this definition or declaration, which is probably not what you want [enabled by default] Signed-off-by: Randy Dunlap Cc: Takashi Iwai Reported-by: Geert Uytterhoeven Signed-off-by: Dave Airlie

vga_switcheroo: Fix error without CONFIG_VGA_SWITCHEROO

2012-06-08T10:51:08Z

Fix a typo that is built only when CONFIG_VGA_SWITCHEROO=n. 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: fix build with non switcheroo enabled path.

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

2011-01-05T03:44:07Z

This adds a hook after the mux is switched for the driver to reprobe the connected outputs. Signed-off-by: Dave Airlie

vga_switcheroo: fix build on platforms with no ACPI

2010-03-01T11:21:58Z

radeon was always including the atpx code unnecessarily, also core switcheroo was including acpi headers. Signed-off-by: Dave Airlie

vga_switcheroo: initial implementation (v15)

2010-03-01T06:20:37Z

Many new laptops now come with 2 gpus, one to be used for low power modes and one for gaming/on-ac applications. These GPUs are typically wired to the laptop panel and VGA ports via a multiplexer unit which is controlled via ACPI methods. 4 combinations of systems typically exist - with 2 ACPI methods. Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method ATI/ATI - some ASUS - use ATPX ACPI Method Intel/Nvidia - - use _DSM ACPI method Nvidia/Nvidia - - use _DSM ACPI method. TODO: This patch adds support for the ATPX method and initial bits for the _DSM methods that need to written by someone with access to the hardware. Add a proper non-debugfs interface - need to get some proper testing first. v2: add power up/down support for both devices on W500 puts i915/radeon into D3 and cuts power to radeon. v3: redo probing methods, no DMI list, drm devices call to register with switcheroo, it tries to find an ATPX method on any device and once there is two devices + ATPX it inits the switcher. v4: ATPX msg handling using buffers - should work on more machines v5: rearchitect after more mjg59 discussion - move ATPX handling to radeon driver. v6: add file headers + initial nouveau bits (to be filled out). v7: merge delayed switcher code. v8: avoid suspend/resume of gpu that is off v9: rearchitect - mjg59 is always right. - move all ATPX code to radeon, should allow simpler DSM also proper ATRM handling v10: add ATRM support for radeon BIOS, add mutex to lock vgasr_priv v11: fix bug in resuming Intel for 2nd time. v12: start fixing up nvidia code blindly. v13: blindly guess at finishing nvidia code v14: remove radeon audio hacks - fix up intel resume more like upstream v15: clean up printks + remove unnecessary igd/dis pointers mount debugfs /sys/kernel/debug/vgaswitcheroo/switch - should exist if ATPX detected + 2 cards. DIS - immediate change to discrete IGD - immediate change to IGD DDIS - delayed change to discrete DIGD - delayed change to IGD ON - turn on not in use OFF - turn off not in use Tested on W500 (Intel/ATI) and T500 (Intel/ATI) Signed-off-by: Dave Airlie
