4cfdcd9cec drm/amdgpu: cleanup on error in amdgpu_cs_ioctl()
We recently changed the locking in this function and now there is a
missing unlock on error.  Also there are some other resources that we
should probably release as well...

bf248ca1f5 drm/i915: Fix locking around GuC firmware load
The GuC firmware load requires struct_mutex to create a GEM object,
but this collides badly with request_firmware. Move struct_mutex
locking down into the loader itself, so we don't hold it across the
entire load process, including request_firmware.

32544d0215 drm/amd/scheduler: don't oops on failure to load
In two places amdgpu tries to tear down something it hasn't
initalised when failing. This is what happens when you
enable experimental support on topaz which then fails in
ring init.

This patch allows it to fail cleanly.

agd: Split out from from the original patch since the
scheduler is a driver independent.

78eaf335e4 drm/nouveau/pll/gk104: fix PLL instability due to bad configuration with gddr5
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

5d5b43f59b drm/nouveau/pci: Handle 5-bit and 8-bit tag field
If the hardware supports extended tag field (8-bit ones), then enable it.

This is usually done by the VBIOS, but not on some MBPs (see fdo#86537).

In case extended tag field is not supported, 5-bit tag field is used which
limits the possible number of requests to 32. Apparently bits 7:0 of
0x08841c stores some number of outstanding requests, so cap it to 32 if
extended tag is unsupported.

Fixes: fdo#86537

v2: Restrict changes to chipsets >= 0x84
v3:
  * Add nvkm_pci_mask to pci.h
  * Mask bit 8 before setting it
v4:
  * Rename `add` argument of nvkm_pci_mask to `value`
  * Move code from nvkm_pci_init to g84_pci_init and remove PCIe and chipset
    checks
v5:
  * Rebase code on latest PCI structure
  * Restore PCIe check
  * Fix namings in nvkm_pci_mask
