From 053075097a053f7f9d8ce01f40ae1b1ad1845fea Mon Sep 17 00:00:00 2001 From: Frederic Barrat Date: Tue, 4 Jul 2023 16:48:48 +0200 Subject: pnv/xive: Allow mmio operations of any size on the ESB CI pages MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We currently only allow 64-bit operations on the ESB CI pages. There's no real reason for that limitation, skiboot/linux didn't need more. However the hardware supports any size, so this patch relaxes that restriction. It impacts both the ESB pages for "normal" interrupts as well as the ESB pages for escalation interrupts defined for the ENDs.
