From 7d8365771ffb0edc336f2cd45e96ef8214a83dca Mon Sep 17 00:00:00 2001 From: Paul Menzel Date: Fri, 3 Jul 2020 16:29:38 +0200 Subject: moduleparams: Add hexint type parameter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For bitmasks printing values in hex is more convenient. Prefix with `0x` to make it clear, that it’s a hex value, and pad it out. Using the helper for `amdgpu.ppfeaturemask`, it will look like below.
