From 59851868a2fb632dbf080feda814137fd60242db Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Tue, 3 Oct 2023 14:30:23 +0200 Subject: [PATCH] accel: Declare AccelClass::cpu_common_[un]realize() handlers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently accel_cpu_realize() only performs target-specific realization. Introduce the cpu_common_[un]realize fields in the base AccelClass to be able to perform target-agnostic [un]realization of vCPUs.
