Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
On GM200 and later GPUs, firmware for some essential falcons (notably
GR ones) must be authenticated by a NVIDIA-produced signature and
loaded by a high-secure falcon in order to be able to access privileged
registers, in a process known as Secure Boot.
Secure Boot requires building a binary blob containing the firmwares
and signatures of the falcons to be loaded. This blob is then given to
a high-secure falcon running a signed loader firmware that copies the
blob into a write-protected region, checks that the signatures are
valid, and finally loads the verified firmware into the managed falcons
and switches them to privileged mode.
This patch adds infrastructure code to support this process on chips
that require it.
v2:
- The IRQ mask of the PMU falcon was left - replace it with the proper
irq_mask variable.
- The falcon reset procedure expecting a falcon in an initialized state,
which was accidentally provided by the PMU subdev. Make sure that
secboot can manage the falcon on its own.

It is not advisable to perform devinit if it has already been done.
VBIOS will very likely have invoked devinit if the GPU is the primary

This patch adds such a method for gf100 and later chips, by means of the

In the display resume path, move the calls to drm_vblank_on()
after the point when the display engine is running again.
Since changes were made to drm_update_vblank_count() in Linux 4.4+
to emulate hw vblank counters via vblank timestamping, the function
drm_vblank_on() now needs working high precision vblank timestamping
and therefore working scanout position queries at time of call.
These don't work before the display engine gets restarted, causing
miscalculation of vblank counter increments and thereby large forward
jumps in vblank count at display resume. These jumps can cause client
hangs on resume, or desktop hangs in the case of composited desktops.
Fix this Linux 4.4 regression by reordering calls accordingly.

gmux is a microcontroller built into dual GPU MacBook Pros.
On pre-retina MBPs, if we're the inactive GPU, we need apple-gmux
to temporarily switch DDC so that we can probe the panel's EDID.
The checks for CONFIG_VGA_ARB and CONFIG_VGA_SWITCHEROO are necessary
because if either of them is disabled but gmux is present, the driver
would never load, even if we're the active GPU. (vga_default_device()
would evaluate to NULL and vga_switcheroo_handler_flags() would
evaluate to 0.)

The pre-retina MacBook Pro uses an LVDS panel and a gmux controller
to switch the panel between its two GPUs. The panel mode in VBIOS
is notoriously bogus on these machines.
Use drm_get_edid_switcheroo() in lieu of drm_get_edid() on LVDS
if the vga_switcheroo handler is capable of temporarily switching
the panel's DDC lines to the discrete GPU. This allows us to retrieve
the EDID if the panel is currently muxed to the integrated GPU.
Likewise, ask vga_switcheroo to switch DDC before probing LVDS
connectors.
This only enables EDID probing on the pre-retina MBP (2008 - 2013).
The retina MBP (2012 - present) uses eDP and gmux is not capable of
switching AUX separately from the main link on these models.
This will be addressed in later patches.

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 separately, the active
client needs to communicate link training parameters to the inactive
client, which may then skip the AUX handshake and set up its output
with these pre-calibrated values (DisplayPort specification v1.1a,
section 2.5.3.3). Clients need a way to recognize such a situation.
The flags for the radeon_atpx_handler and amdgpu_atpx_handler are
initially set to 0, this can later on be amended with
handler_flags |= VGA_SWITCHEROO_CAN_SWITCH_DDC;
when a ->switch_ddc callback is added.

The new debugfs initialization code fails to build when CONFIG_DEBUG_FS
is disabled:
In file included from /git/arm-soc/drivers/gpu/drm/nouveau/nouveau_drm.c:57:0:
drivers/gpu/drm/nouveau/nouveau_debugfs.h: In function 'nouveau_debugfs_init':
drivers/gpu/drm/nouveau/nouveau_debugfs.h:37:29: error: parameter name omitted
nouveau_debugfs_init(struct nouveau_drm *)
This fixes the prototypes so we can build it again.

move printing of pcie speeds into oneinit,
rename all pcie functions to nvkm_pcie_*
don't try to raise the pcie version when no higher one is supported
v5: revert Copyright changes and rename nvkm_pcie_raise_version to nvkm_pcie_set_version
v6: remove some useless pci_is_pcie checks and rework messages
