The display power well support on this platform is in a somewhat broken state atm, so disable it by default. This in effect will get rid of incorrect assert WARNs about the CSR/DMC firmware not being loaded during power well toggling. It also removes a problem during driver loading where a register is accessed while its backing power well is down, resulting in another WARN. Until we come up with the root cause of the second problem and the proper fix for both issues, keep all display side power wells on. Also clarify a bit the option description. Reported-by:

We have a timed release of a forcewake when using I915_READ/WRITE macros. wait_for() macro will go to quite long sleep if the first read doesn't satisfy the condition for successful exit. With these two interacting, it is possible that we lose the forcewake during the wait_for() and the subsequent read will reaquire forcewake. Further experiments with skl shows that when we lose forcewake, we lose the reset request we submitted. So reset request register is not power context saved. Grab forcewakes for all engines before starting the reset/request dance so that all requests stay valid for the duration of reset requisition across all the engines. v2: Add comment on power well sleeps. Wrap the reset handling under forcewake instead of just reset requests (Chris) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=92774 Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by:Chris Wilson <chris@chris-wilson.co.uk> Tested-by: Tomi Sarvela <tomix.p.sarvela@intel.com> (v1, v2) Signed-off-by:

While pinning a fb object to the display plane, only install a fence if the object is using a normal view. This corresponds with the behavior found in i915_gem_object_do_pin() where the fencability criteria is determined only for objects with normal views. v2: Look at the object's map_and_fenceable flag to determine whether to install a fence or not (Chris). v3: Pin and unpin a fence only if the current view type is normal. v4: Extend the "view type is normal" check for pin_fence as well.

hda_intel.c:azx_probe() defers initialization of an audio controller on the discrete GPU if the GPU is powered off. The power state of the GPU is determined by calling vga_switcheroo_get_client_state(). vga_switcheroo_get_client_state() returns VGA_SWITCHEROO_INIT if vga_switcheroo is not enabled, i.e. if no second GPU or no handler has registered. This can go wrong in the following scenario: - Driver for the integrated GPU is not loaded. - Driver for the discrete GPU registers with vga_switcheroo, uses driver power control to power down the GPU, handler cuts power to the GPU. - Driver for the audio controller gets loaded after the GPU was powered down, calls vga_switcheroo_get_client_state() which returns VGA_SWITCHEROO_INIT instead of VGA_SWITCHEROO_OFF. - Consequence: azx_probe() tries to initialize the audio controller even though the GPU is powered down. The power state VGA_SWITCHEROO_INIT was introduced by c8e9cf7b ("vga_switcheroo: Add a helper function to get the client state"). It is not apparent what its benefit might be. The idea seems to be to initialize the audio controller even if the power state is VGA_SWITCHEROO_OFF (were vga_switcheroo enabled), but as shown above this can fail. Drop VGA_SWITCHEROO_INIT to solve this. Acked-by:

This patch uses an approach closer to the nvidia driver to configure both PLLs for high gddr5 memory clocks (usually above 2400MHz) Previously nouveau used the one PLL as it was used for the lower clocks and just adjusted the second PLL to get as close as possible to the requested clock. This means for my card, that I got a 4050 MHz clock although 4008 MHz was requested. Now the driver iterates over a list of PLL configuration also used by the nvidia driver and then adjust the second PLL to get near the requested clock. Also it hold to some restriction I found while analyzing the PLL configurations This won't fix all gddr5 high clock issues itself, but it should be fine on hybrid gpu systems as found on many laptops these days. Also switching while normal desktop usage should be a lot more stable than before. v2: move the pll code into ramgk104 Signed-off-by:

Avoids waiting for VBLANKS that never arrive on headless or otherwise unconventional set-ups. Strategy taken from MEMX. Signed-off-by:

10053c is not even read on some cards, and I have no idea exactly what the criteria are. Likely NVIDIA pre-scans the VBIOS and in their driver disables all features that are never used. The practical effect should be the same as this implementation though. Signed-off-by:

Like Pierre's G94. We might want to structure Kepler similarly in a follow-up. Signed-off-by:
