[igt-dev] [PATCH i-g-t v8 00/14] vm_bind: Add VM_BIND validation support

[Niranjana Vishwanathapura]

DRM_I915_GEM_VM_BIND/UNBIND ioctls allows UMD to bind/unbind GEM
buffer objects (BOs) or sections of a BOs at specified GPU virtual
addresses on a specified address space (VM). Multiple mappings can map
to the same physical pages of an object (aliasing). These mappings (also
referred to as persistent mappings) will be persistent across multiple
GPU submissions (execbuf calls) issued by the UMD, without user having
to provide a list of all required mappings during each submission (as
required by older execbuf mode).

The new execbuf3 ioctl (I915_GEM_EXECBUFFER3) will only work in vm_bind
mode. The vm_bind mode only works with this new execbuf3 ioctl.

Add tests to validate the VM_BIND, VM_UNBIND and execbuf3 ioctls and
various scenarios involving persistent mappings.

TODOs:
* More validation support.
* Port some relevant gem_exec_* tests for execbuf3.

NOTEs:
* It is based on below VM_BIND design+uapi rfc.
  Documentation/gpu/rfc/i915_vm_bind.rst

* The i915 VM_BIND support is posted as,
  [PATCH v8 00/22] drm/i915/vm_bind: Add VM_BIND functionality

v2: Address various review comments
v3: Add gem_exec3_basic and gem_exec3_balancer tests,
    add gem_lmem_swapping@vm_bind subtest and some fixes.
v4: Add and use i915_vm_bind library functions,
    add lmem test if lmem region is present instead of skipping,
    remove helpers to create vm_private objects, instead use
    gem_create_ext() function.
v5: Use memory region's gtt_alignment, use non-recoverable faults,
    fix review comments.
v6: Rebased, add sanity tests for added reserved uapi fields,
    add gem_shrink@vm_bind* subtests.
v7: Pull in uapi changes and address review comments
v8: Rebased, add capture test

[Niranjana Vishwanathapura]

Add sanity test to exercise vm_bind uapi.
Test for various cases with vm_bind and vm_unbind ioctls.

v2: Add more input validity tests
    Add sanity test to fast-feedback.testlist
v3: Add only basic-smem subtest to fast-feedback.testlist
v4: Use gem_create_ext to create vm private objects,
    Ensure vm private objects are only allowed in vm_bind mode,
    Use library routine i915_vm_bind_version()
v5: Add execbuf3 sanity tests, use mr->gtt_alignment,
    add non-recoverable context sanity test
v6: Add more execbuf3 sanity tests
v7: Port as per uapi reserved field changes
v8: Validate partial binding

[igt-dev] [PATCH i-g-t v8 08/14] tests/i915/vm_bind: Add basic VM_BIND test support

[Niranjana Vishwanathapura]

Add basic tests for VM_BIND functionality. Bind the buffer objects in
device page table with VM_BIND calls and have GPU copy the data from a
source buffer object to destination buffer object.
Test for different buffer sizes, buffer object placement and with
multiple contexts.

v2: Add basic test to fast-feedback.testlist
v3: Run all tests for different memory types,
    pass VA instead of an array for batch_address
v4: Iterate for memory region types instead of hardcoding,
    use i915_vm_bind library functions
v5: Validate synchronous vm_bind, require blt engine,
    use mr->gtt_alignment instead of HAS_64K_PAGES,
    change info to debug messages, remove igt_collection usage,
    fix dg2 alignment issue
v6: Port as per uapi reserved field changes

[igt-dev] [PATCH i-g-t v8 09/14] tests/i915/vm_bind: Add userptr subtest

[Niranjana Vishwanathapura]

Add userptr object type to vm_bind_basic test.

v2: Run all tests for userptr type
v3: Change info to debug messages, remove igt_collection usage
v4: only munmap non-userptr objects

[igt-dev] [PATCH i-g-t v8 11/14] tests/i915/vm_bind: Add gem_exec3_balancer test

[Niranjana Vishwanathapura]

To test parallel submissions support in execbuf3, port the subtest
gem_exec_balancer@parallel-ordering to a new gem_exec3_balancer test
and switch to execbuf3 ioctl.

v2: use i915_vm_bind library functions
v3: Remove unwanted gem_set_domain()
v4: Require guc submission

[igt-dev] [PATCH i-g-t v8 12/14] tests/i915/vm_bind: Add gem_lmem_swapping@vm_bind sub test

[Niranjana Vishwanathapura]

Validate eviction of objects with persistent mappings and
check persistent mappings are properly rebound upon subsequent
execbuf3 call.

TODO: Add a new swapping test with just vm_bind mode
      (without legacy execbuf).

v2: use i915_vm_bind library functions
v3: fix dg2 alignment issue
