Turing adds a second top-level interrupt tree in HW, in addition to the
trees available via NV_PMC. Most of the interrupts we care about are
exposed in both trees, but not all of them, and we have some rather
nasty hacks to route the fault buffer interrupts.
Ampere removes the NV_PMC trees entirely.
Here we add some infrastructure to be able to handle all of this more
cleanly, as well as providing more explicit control over handlers.

The vblank and nonstall events have some annoying interactions with DRM
locking, and aren't able to do certain things as a result.
However, other uses of event notifications don't have such requirements,
and upcoming patches take advantage of this for various improvements.
Having separate classes for each nvkm_event's spinlocks allows lockdep
to distinguish between them and avoid false-positives.

This removes support for accelerated fbcon rendering, and fixes a number
of races/crashes/issues around suspend/resume/module unload etc.
Losing HW accelerated rendering isn't ideal, but it's been significantly
reduced in performance since the removal of accelerated scrolling in the
kernel anyway - not to mention, can be racey (skips cpu<->gpu sync) from
certain contexts.

This replaces the twisty, confusing, relationship between nvkm_event and
nvkm_notify with something much simpler, and less racey. It also places
events in the object tree hierarchy, which will allow a heap of the code
tracking events across allocation/teardown/suspend to be removed.
This commit just adds the new interfaces, and passes the owning subdev to
the event constructor to enable debug-tracing in the new code.

This moves control of link retraining in response to HPD IRQ to the
KMS driver's HPD IRQ handler.
NVKM still handles checking link status for the moment, this can be

Aside from fixing MST->SST switching (KMS never turned off MST link config),
this should preserve existing behaviour for the moment, but provide a path
for the KMS driver to have more explicit control of the DP link, which has
been requested by Lyude.
More research into modeset/supervisor interactions is needed before we can
have fully explicit control from the KMS driver.

There are various pieces of information we pass to NVKM about the next
modeset, which are generally used while handling supervisor interrupts.
We had to start passing in some information about audio requirements a
while back to allocate an appropriate SOR in ACQUIRE, so we may as well
move all this type of information here for other protocols too.
Certain methods will be blocked on non-acquired outputs now, preventing
NULL pointer derefs from KMS driver bugs.

On ilk the UDW of TIMESTAMP increments every 1000 ns,
LDW is mbz. In order to represent that we'd need 52 bits,
but we only have 32 bits. Even worse most things want to
only deal with 32 bits of timestamp. So let's just set
up the timestamp frequency as if we only had the UDW.
On ctg/elk 63:20 of TIMESTAMP increments every 1/4 ns, 19:0
are mbz. To make life simpler let's ignore the LDW and set up
timestamp frequency based on the UDW only (increments every
1024 ns).

The RTNI field is multiplied by 16 and incremented by 512 before being
used as the minimum number of pixel clock per horizontal line, hence
it is necessary to subtract those 512 bytes from htotal and then divide
the result by 16 before writing the value into the RTNI field. Fix the
calculation.

If a axi bus master with a higher priority do a lot of memory access
FIFO underruns can be inspected. Increase the burst size to 256B to
avoid such underruns and to improve the memory access efficiency.

Cursor snooping depended on implicit size and format which made debugging
quite difficult. Make the code easier to following by making everything
explicit and instead of using magic numbers predefine all the
parameters the code depends on.
Also fixes incorrectly computed pitches for non-aligned cursor snoops.
Fix which has no practical effect because non-aligned cursor snoops
are not used by the X11 driver and Wayland cursors will go through
mob cursors, instead of surface dma's.

Invalid userspace dma surface copies could potentially overflow
the memcpy from the surface to the snooped image leading to crashes.
To fix it the dimensions of the copybox have to be validated
against the expected size of the snooped cursor.
