Another vga_switcheroo cleanup. Maintainers, is it okay to include the one-line change of each driver in here or do you want that split into separate patches?

...n. Caution: Patch [09/12] depends on a new acpi_dev_present() API which will land in 4.5 via Rafael J. Wysocki's tree. I would particularly be interested in feedback on the handler flags patch [01/12]. I'm not 100% happy with the number of characters required to query the flags (e.g.: if (vga_switcheroo_handler_flags() & VGA_SWITCHEROO_CAN_SWITCH_DDC)), but failed to come up with something shorter. Thierry Reding used a struct of bools instead of a bitmask for his recent drm_dp_link_caps patches. Maybe use that instead? http://lists.freedesktop.org/archives/dri-devel/2015-December/097025.html Thank...

Hi, Here are two patches to fix an issue reported on kernel bugzilla (infinite loop due to unchecked function) and a more important fix to fix hanging Optimus machines when runtime PM is enabled (with pm/pci patches). An older (obsolete) patch for the first issue was tested by the reporter: https://bugzilla.kernel.org/show_bug.cgi?id=104791#c11 (it is replaced by "check for function 0x1B

Hi, Here are two patches to fix an issue reported on kernel bugzilla (infinite loop due to unchecked function) and a more important fix to fix hanging Optimus machines when runtime PM is enabled (with pm/pci patches). See the first version[1] for a background on the fixed problems. This is the second revision of incorporating feedback from Emil Velikov (patch 1), Mika Westerberg (patch 4).

The method struct vga_switcheroo_handler::get_client_id() is defined as returning an 'enum vga_switcheroo_client_id' but the implementation in this driver, nouveau_dsm_get_client_id(), returns an 'int'. Fix this by returning 'enum vga_switcheroo_client_id' in this driver too. Signed-off-by: Luc Van Oostenryck &...

Hi, Here are two patches to fix an issue reported on kernel bugzilla (infinite loop due to unchecked function) and a more important fix to fix hanging Optimus machines when runtime PM is enabled (with pm/pci patches). These are the final patches targeting v4.8. Changes compared to v2[1]: collected R-b from Hans and Mika and fixed a minor comment style issue. I recommend it to be merged before
