Merge tag 'drm-next-2020-10-15' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "Not a major amount of change, the i915 trees got split into display
  and gt trees to better facilitate higher level review, and there's a
  major refactoring of i915 GEM locking to use more core kernel concepts
  (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards
  get DC support, nouveau got a bump in displayport support with common
  code extraction from i915.

  Outside of drm this contains a couple of patches for hexint
  moduleparams which you've acked, and a virtio common code tree that

72e71a82d6 drm/amdgpu: add new trace event for page table update
This patch adds a new trace event to track the PTE update
events. This specific event will provide information like:
- start and end of virtual memory mapping
- HW engine flags for the map
- physical address for mapping

This will be particularly useful for memory profiling tools
(like RMV) which are monitoring the page table update events.

V2: Added physical address lookup logic in trace point
V3: switch to use __dynamic_array
    added nptes int the TPprint arguments list
    added page size in the arg list
V4: Addressed Christian's review comments
    add start/end instead of seg
    use incr instead of page_sz to be accurate
V5: Addressed Christian's review comments:
    add pid and vm context information in the event
V6: Re-sequence the variables (put pid and ctx_id first)

c7b6bac9c7 drm, iommu: Change type of pasid to u32
PASID is defined as a few different types in iommu including "int",
"u32", and "unsigned int". To be consistent and to match with uapi
definitions, define PASID and its variations (e.g. max PASID) as "u32".
"u32" is also shorter and a little more explicit than "unsigned int".

No PASID type change in uapi although it defines PASID as __u64 in
some places.

8b80d74bdb drm/amdgpu: restrict bo mapping within gpu address limits
Have strict check on bo mapping since on some systems, such as A+A or
hybrid, the cpu might support 5 level paging or can address memory above
48 bits but gpu might be limited by hardware to just use 48 bits. In
general, this applies to all asics where this limitation can be checked
against their max_pfn range. This restricts the range to map bo within
pratical limits of cpu and gpu for shared virtual memory access.

b4672c8a84 amd/amdgpu: force to trigger a no-retry-fault after a retry-fault
Only for the debugger use case.

[why]
Avoid endless translation retries, after an invalid address access has
been issued to the GPU. Instead, the trap handler is forced to enter by
generating a no-retry-fault.
A s_trap instruction is inserted in the debugger case to let the wave to
enter trap handler to save context.

[how]
Intentionally using an invalid flag combination (F and P set at the same
time) to trigger a no-retry-fault, after a retry-fault happens. This is
only valid under compute context.

Instead of skipping the root PD while processing the relocated list just never
put it on the list in the first place.

This avoids walking the list all together when the root PD is the only entry
