From 35f6b46eeb033c05b6668755d5c1fd20702aedb6 Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Wed, 14 Feb 2024 09:59:01 -0800 Subject: [PATCH] ionic: set adminq irq affinity [ Upstream commit c699f35d658f3c21b69ed24e64b2ea26381e941d ] We claim to have the AdminQ on our irq0 and thus cpu id 0, but we need to be sure we set the affinity hint to try to keep it there.
