Over time we had several patches having to change both places to keep them in sync (and some patches failing to do so). The initial idea was to remove i915_frequency_info, but there are user space tools using it. From a quick code search there are other scripts and test tools besides igt, so it's not simply updating igt to get rid of the older file. Here we export a function using drm_printer as parameter and make both show() implementations to call this same function. Aside from a few variable name differences, for i915_frequency_info this brings a few lines that were not previously printed: RP UP EI, RP UP THRESHOLD, RP DOWN THRESHOLD and RP DOWN EI. These came in as part of commit 9c878557b1eb ("drm/i915/gt: Use the RPM config register to determine clk frequencies"), which didn't change both places.

Over time we had several patches having to change both places to keep them in sync (and some patches failing to do so). The initial idea was to remove i915_frequency_info, but there are user space tools using it. From a quick code search there are other scripts and test tools besides igt, so it's not simply updating igt to get rid of the older file. Here we export a function using drm_printer as parameter and make both show() implementations to call this same function. Aside from a few variable name differences, for i915_frequency_info this brings a few lines that were not previously printed: RP UP EI, RP UP THRESHOLD, RP DOWN THRESHOLD and RP DOWN EI. These came in as part of commit 9c878557b1eb ("drm/i915/gt: Use the RPM config register to determine clk frequencies"), which didn't change both places.
