[PATCH 1/8] acpi: Rename v1 DSM to mux to avoid ambiguity
This is especially true when variables or functions are just called dsm without

[PATCH] drm/nouveau: fix mode_valid's return type
The method struct drm_connector_helper_funcs::mode_valid is defined
as returning an 'enum drm_mode_status' but the driver implementation
for this method uses an 'int' for it.
Fix this by using 'enum drm_mode_status' in the driver too.

[PATCH 0/1] vga_switcheroo: Constify vga_switcheroo_handler
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?
Thanks,
Lukas

[PATCH v5 01/12] vga_switcheroo: Add handler flags infrastructure
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

[PATCH 1/1] drm/nouveau: Use generic helper to check _PR3 presence
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.

[PATCH 4/4] drm/nouveau/acpi: fix lockup with PCIe runtime PM
Since "PCI: Add runtime PM support for PCIe ports", the parent PCIe port
can be runtime-suspended which disables power resources via ACPI. This
is incompatible with DSM, resulting in a GPU device which is still in D3
and locks up the kernel on resume.
Mirror the behavior of Windows 8 and newer[1] (as observed via an AMLi
debugger trace) and stop using the DSM functions for D3cold when

[PATCH v2 1/4] drm/nouveau/acpi: ensure matching ACPI handle and supported functions
Ensure that the returned set of supported DSM functions (MUX, Optimus)
match the ACPI handle that is set in nouveau_dsm_pci_probe.
As there are no machines with a MUX function on just one PCI device and
an Optimus on another, there should not be a functional impact. This
change however makes this implicit assumption more obvious.
Convert int to bool and rename has_dsm to has_mux while at it. Let

[PATCH] drm/nouveau: check function before using it
Do not unconditionally invoke function 0x1B without checking for its
availability, it leads to an infinite loop on some firmware.

What does the code mean?
Hello,
These days I am reading nouveau source code,but I cannot understand this code!
Please look at http://codepad.org/61v3mXmq .
The function ‘nouveau_dsm_power_state’ said optimus is disabled in another function ‘nouveau_switcheroo_set_state’.
But in fact,the function ‘nouveau_switcheroo_set_state’ will return directly when optimus is detected!
Both of these functions won’t disable

[PATCH v3] drm: don't set the pci power state if the pci subsystem handles the ACPI bits
When looking into the runpm issues, the first workaround I came up with
was setting the PCIe link speed to whatever it was before running devinit
on the GPU.
As I was playing around with my patches today, it seems like that just
reworking the runpm bits itself fixed it on my machine as well. Hopefully
this will be enough for other laptops as well.
Anyhow, it's a nice rework and if it's

[PATCH RFC] nouveau: Add support for Gmux _DSM method
This patch certainly needs some more work, but I'd like 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.
