From afca92071fc12402a8dee1ad68f66f22dd4b9872 Mon Sep 17 00:00:00 2001 From: Frederic Barrat Date: Thu, 1 Jun 2023 14:13:30 +0200 Subject: pnv/xive2: Introduce macros to manipulate TIMA addresses MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit TIMA addresses are somewhat special and are split in several bit fields with different meanings. This patch describes it and introduce macros to more easily access the various fields.
