drm/i915/uapi: tweak error capture on recoverable contexts
A non-recoverable context must be used if the user wants proper error
capture on discrete platforms. In the future the kernel may want to blit
the contents of some objects when later doing the capture stage. Also
extend to newer integrated platforms.
v2(Thomas):
- Also extend to newer integrated platforms, for capture buffer memory
allocation purposes.
v3 (Reported-by: kernel test robot <[email protected]>):
- Fix build on !CONFIG_DRM_I915_CAPTURE_ERROR
Testcase: igt@gem_exec_capture@capture-recoverable
