[igt-dev] [PATCH i-g-t v2] tools/i915-perf-recorder: fix topology alignment issue

[Chris Wilson]

Quoting Lionel Landwerlin (2020-04-01 12:55:13)
> The additional alignment added when writing into the output was not
> accounted in the header. This is preventing reading the recorded data.
> 
> Instead of adding the alignment when writing, just account for it when
> querying the topology.
> 
> v2: Use calloc
>     Drop unused var
