[PATCH 1/2] drm/i915: Make i915_engine_info pretty printer to standalone

[PATCH 1/2] drm/i915: Make i915_engine_info pretty printer to standalone

[Chris Wilson]

We can use drm_printer to hide the differences between printk and
seq_printf, and so make the i915_engine_info pretty printer able to be
called from different contexts and not just debugfs. For instance, I
want to use the pretty printer to debug kselftests.

[PATCH 2/2] drm/i915/selftests: Pretty print engine state when requests fail to start

[Chris Wilson]

During hangcheck testing, we try to execute requests following the GPU
reset, and in particular want to try and debug when those fail.
