From ecbce923713d736b45696e438ea024e780fd58b7 Mon Sep 17 00:00:00 2001 From: Michal Privoznik Date: Fri, 16 Jun 2023 13:05:48 +0200 Subject: [PATCH] qemu: Adapt to new way of specifying PC speaker Historically, the way to set PC speaker for a guest was to pass: -soundhw pcspk but as of QEMU commit v5.1.0-rc0~28^2~3 this is deprecated and we should use: -machine pcspk-audiodev=$id instead. The old way was then removed in commit v7.1.0-rc0~99^2~3. Now, ideally we would have a capability selecting whether we talk to a QEMU that understands the new way or not. But it's not that simple - the machine attribute is just an alias to the .audiodev= attribute of 'isa-pcspk' object and both are created in pc_machine_initfn() function, i.e. not then the PC_MACHINE() class is initialized, but when it's instantiated. IOW, it's not possible for us to query whether we're dealing with older or newer QEMU. But given that the newer version is supported since v5.1.0 and the minimal version we require is v4.2.0 (i.e. there are two releases which don't understand the newer cmd line) and how frequently this feature is (un-)used (the issue was reported after ~1 year since it stopped working), I believe we can live without any capability and just use the newer cmd line unconditionally.
