From 75e13be918f567469054a2bc387d202b0848757b Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Sat, 2 Nov 2013 14:10:18 +0100 Subject: [PATCH 111/212] rhel: Drop "cfi.pflash01" and "isa-ide" device RH-Author: Markus Armbruster Message-id: <1383401418-4444-3-git-send-email-armbru@redhat.com> Patchwork-id: 55269 O-Subject: [PATCH 7.0 qemu-kvm 2/2] rhel: Drop "cfi.pflash01" and "isa-ide" device Bugzilla: 1001076 RH-Acked-by: Paolo Bonzini RH-Acked-by: Marcel Apfelbaum RH-Acked-by: Alex Williamson From: Markus Armbruster We can drop a device from the build only when it isn't referenced from code we build. References come in two forms: extern symbols, and qdev driver names. Unresolved extern symbols pose no real danger, because they fail safely at link time. Note for the curious: the optimizer gets rid of the reference to isa_ide_init() in hw/i386/pc_piix.c. Unresolved driver names get detected only at runtime, so we better be extra careful. There is just one occurence of either driver name outside the code dropped by this patch: "isa-ide" in hw/isa/pc87312.c. Compiled only when CONFIG_PC87312 is enabled. It isn't in our build. "cfi.pflash01" is already no-user. Drop it anyway, because it's easy and safe.
