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 --- drivers/gpu/drm/i915/i915_dma.c | 35 +++ drivers/gpu/drm/i915/i915_drv.c | 4 +- drivers/gpu/drm/i915/i915_drv.h | 2 + drivers/gpu/drm/i915/intel_fb.c | 2 + drivers/gpu/drm/nouveau/nouveau_acpi.c | 160 +++++++--- drivers/gpu/drm/nouveau/nouveau_drv.c | 9 +- drivers/gpu/drm/nouveau/nouveau_drv.h | 19 +- drivers/gpu/drm/nouveau/nouveau_fbcon.c | 2 + drivers/gpu/drm/nouveau/nouveau_state.c | 32 +- drivers/gpu/drm/radeon/Makefile | 3 +- drivers/gpu/drm/radeon/radeon.h | 8 + drivers/gpu/drm/radeon/radeon_atpx_handler.c | 258 +++++++++++++++ drivers/gpu/drm/radeon/radeon_bios.c | 44 ++- drivers/gpu/drm/radeon/radeon_device.c | 40 +++ drivers/gpu/drm/radeon/radeon_drv.c | 2 + drivers/gpu/drm/radeon/radeon_drv.h | 3 + drivers/gpu/drm/radeon/radeon_fb.c | 3 + drivers/gpu/drm/radeon/radeon_kms.c | 3 + drivers/gpu/vga/Kconfig | 13 + drivers/gpu/vga/Makefile | 1 + drivers/gpu/vga/vga_switcheroo.c | 453 +++++++++++++++++++++++++++ drivers/video/console/fbcon.c | 18 ++ include/linux/fb.h | 2 + include/linux/vga_switcheroo.h | 58 ++++ 24 files changed, 1104 insertions(+), 70 deletions(-) create mode 100644 drivers/gpu/drm/radeon/radeon_atpx_handler.c create mode 100644 drivers/gpu/vga/vga_switcheroo.c create mode 100644 include/linux/vga_switcheroo.h (limited to 'drivers/video') diff --git a/drivers/gpu/drm/i915/i915_dma.c b/drivers/gpu/drm/i915/i915_dma.c index 2307f98349f..42ca07f04a2 100644 --- a/drivers/gpu/drm/i915/i915_dma.c +++ b/drivers/gpu/drm/i915/i915_dma.c @@ -35,6 +35,7 @@ #include "i915_drv.h" #include "i915_trace.h" #include +#include /* Really want an OS-independent resettable timer.

This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy Acked-by: David Teigland Acked-by: Matt Domsch Acked-by: Maciej Sosnowski Acked-by: Hans J.

charset=UTF-8 Content-Transfer-Encoding: 8bit A pointer to a probe callback is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.
