If I understand it correctly, if the laptop is an Optimus one or has a mux, we are not "allowed" to opt-out of DynPwr/DynOff by powering down the card?
In the same commit adding this conditional (5addcf0a5f0fadceba6bd562d0616a1c5d4c1a4d), you added the possibility to enable/disable dynp...

[PATCH 0/7] Modernize vga_switcheroo by using device link for HDA
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

[PATCH v2 0/7] Modernize vga_switcheroo by using device link for HDA
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)

[PATCH RFC] nouveau: Add support for Gmux _DSM method
...to get some comments.
Not sure if it is really related to the gmux or if it is a different Optimus
_DSM version.
I tested it on my laptop (MCP79/7A + G96) and the G96 successfully goes to
sleep, however it is still marked as PWR in vga_switcheroo, despite
`vga_switcheroo_set_dynamic_switch(pdev, VGA_SWITCHEROO_OFF)` being called.

[PATCH 0/5] Fix deadlock on runtime suspend in DRM drivers
Fix a deadlock on hybrid graphics laptops that's been present since 2013:
DRM drivers poll connectors in 10 sec intervals. The poll worker is
stopped on ->runtime_suspend with cancel_delayed_work_sync(). However
the poll worker invokes the DRM drivers' ->detect callbacks, which call
pm_runtime_get_sync(). If the poll worker starts after runtime suspend
has begun,

[PATCH v5 00/12] Enable GPU switching on pre-retina MacBook Pro
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
