From 74ac7c81788198342d1dd60f95fa4870fa64728e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Roger=20Pau=20Monn=C3=A9?= Date: Wed, 12 Aug 2020 14:47:05 +0200 Subject: [PATCH] x86/hvm: change EOI exit bitmap helper parameter MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Change the last parameter of the update_eoi_exit_bitmap helper to be a set/clear boolean instead of a triggering field. This is already inline with how the function is implemented, and will allow deciding whether an exit is required by the higher layers that call into update_eoi_exit_bitmap. Note that the current behavior is not changed by this patch. No functional change intended.
