From 33e1d4a152ce55272b54a16884461218d12d4f1b Mon Sep 17 00:00:00 2001 From: Cédric Le Goater Date: Fri, 5 Nov 2021 11:26:31 +0100 Subject: powerpc/xive: Rename the 'cpus' debugfs file to 'ipis' MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit and remove the EQ entries output which is not very useful since only the next two events of the queue are taken into account. We will improve the dump of the EQ in the next patches.
