similar to: [PATCH 0/1] vga_switcheroo: Constify vga_switcheroo_handler

Enable GPU switching on the pre-retina MacBook Pro (2008 - 2013), v5. The main obstacle on these machines is that the panel mode in VBIOS is bogus. Fortunately gmux can switch DDC independently from the display, thereby allowing the inactive GPU to probe the panel's EDID. In short, vga_switcheroo and apple-gmux are amended with hooks to switch DDC, DRM core is amended with a

Allow handlers to declare their capabilities and allow clients to obtain that information. So far we have these use cases: * If the handler is able to switch DDC separately, clients need to probe EDID with drm_get_edid_switcheroo(). We should allow them to detect a capable handler to ensure this function only gets called when needed. * Likewise if the handler is unable to switch AUX

Modernize vga_switcheroo by using a "device link" to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into. Remove thereby obsoleted code and fix a bunch of bugs. Device links were introduced in v4.10. Users might see a small power saving if the discrete GPU is in use and its HDA controller is not, because the HDA controller is now allowed to runtime

I can confirm what Peter said, path contains \_SB_.PCI0.RP05 and power_state contains D3hot.

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).

Replace nouveau_pr3_present() in favor of a more generic one, pci_pr3_present(). Also the presence of upstream bridge _PR3 doesn't need to go hand in hand with device's _DSM, so check _PR3 before _DSM.

Since the image pointed to may (and generally will) live in boot services memory (which we add to the global memory pool long before ACPI tables get looked at), we should prevent Dom0 from trying to retrieve the image data. The alternatives would be to - not add boot services memory to the global pool at all, or - defer adding boot services memory until Dom0 indicates it is safe to do so, or -

Modernize vga_switcheroo by using a device link to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into, v2. Changes since v1: - Replace patch [1/7] to use pci_save_state() / pci_restore_state() for consistency between runtime PM code path of bound and unbound devices. (Rafael, Bjorn) - Patch [5/7]: Drop an unnecessary initialization. (Bjorn) Rephrase

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

Do not unconditionally invoke function 0x1B without checking for its availability, it leads to an infinite loop on some firmware.

Hi all, i still have problem.. Some time I am able to install and other not. I tried this on different machine either in a pool and either in a single installation of XCP.

Any takers? Merging this would allow fdo #61115 to be closed (currently assigned to intel-gfx). FWIW this series has in the meantime been tested by more folks: Tested-by: Pierre Moreau
