From c6ccb691d484544636bc4a097574c5c135ccccda Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 4 Sep 2024 16:30:48 +0200 Subject: [PATCH] pmdomain: core: Reduce debug summary table width Commit 9094e53ff5c86ebe ("pmdomain: core: Use dev_name() instead of kobject_get_path() in debugfs") severely shortened the names of devices in a PM Domain. Now the most common format[1] consists of a 32-bit unit-address (8 characters), followed by a dot and a node name (20 characters for "air-pollution-sensor" and "interrupt-controller", which are the longest generic node names documented in the Devicetree Specification), for a typical maximum of 29 characters. This offers a good opportunity to reduce the table width of the debug summary: - Reduce the device name field width from 50 to 30 characters, which matches the PM Domain name width, - Reduce the large inter-column space between the "performance" and "managed by" columns. Visual impact: - The "performance" column now starts at a position that is a multiple of 16, just like the "status" and "children" columns, - All of the "/device", "runtime status", and "managed by" columns are now indented 4 characters more than the columns right above them, - Everything fits in (one less than) 80 characters again ;-) [1] Note that some device names (e.g. TI AM335x interconnect target modules) do not follow this convention, and may be much longer, but these didn't fit in the old 50-character column width either.
