The report seems to be valid, but I don't think this is the fix.

Where do we even check for invalid instance/uabi_instance in code?

The whole thing seems rather poorly documented as there's a matching
uabi struct with __u16's and the negative values are defined right
there in the uapi header as well.

Negative ones are exception values to be used in conjunction with the virtual engine uapi (see "DOC: Virtual Engine uAPI" and also comment next to I915_CONTEXT_PARAM_ENGINES).

AFAIK assigning negative int to unsigned int is defined and fine.

Compiler does warn on comparisons which is why we have:

./gem/i915_gem_busy.c:  if (id == (u16)I915_ENGINE_CLASS_INVALID)
./gem/i915_gem_busy.c:  if (id == (u16)I915_ENGINE_CLASS_INVALID)
./gem/i915_gem_context.c:               if (ci.engine_class == (u16)I915_ENGINE_CLASS_INVALID &&
./gem/i915_gem_context.c:                   ci.engine_instance == (u16)I915_ENGINE_CLASS_INVALID_NONE)

So I think no action needed here.

Negative ones are exception values to be used in conjunction with the virtual engine uapi (see "DOC: Virtual Engine uAPI" and also comment next to I915_CONTEXT_PARAM_ENGINES).

AFAIK assigning negative int to unsigned int is defined and fine.

Compiler does warn on comparisons which is why we have:

./gem/i915_gem_busy.c:  if (id == (u16)I915_ENGINE_CLASS_INVALID)
./gem/i915_gem_busy.c:  if (id == (u16)I915_ENGINE_CLASS_INVALID)
./gem/i915_gem_context.c:               if (ci.engine_class == (u16)I915_ENGINE_CLASS_INVALID &&
./gem/i915_gem_context.c:                   ci.engine_instance == (u16)I915_ENGINE_CLASS_INVALID_NONE)

So I think no action needed here.

Tvrtko

We never check instance or uabi_instance members against
I915_ENGINE_CLASS_INVALID_VIRTUAL anywhere.
