From a1b40bda089e39b4dfad3cea72a696eb7bdef58e Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 22 Jun 2020 11:42:19 +0200 Subject: blockdev: Deprecate -drive with bogus interface type Drives with interface types other than if=none are for onboard devices. Unfortunately, any such drives the board doesn't pick up can still be used with -device, like this: $ qemu-system-x86_64 -nodefaults -display none -S -drive if=floppy,id=bogus,unit=7 -device ide-cd,drive=bogus -monitor stdio QEMU 5.0.50 monitor - type 'help' for more information (qemu) info block bogus: [not inserted] Attached to: /machine/peripheral-anon/device[0] Removable device: not locked, tray closed (qemu) info qtree bus: main-system-bus type System [...] bus: ide.1 type IDE dev: ide-cd, id "" ---> drive = "bogus" [...] unit = 0 (0x0) [...] This kind of abuse has always worked. Deprecate it: qemu-system-x86_64: -drive if=floppy,id=bogus,unit=7: warning: bogus if=floppy is deprecated, use if=none Signed-off-by: Markus Armbruster Message-Id: <20200622094227.1271650-9-armbru@redhat.com> --- include/sysemu/blockdev.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include') diff --git a/include/sysemu/blockdev.h b/include/sysemu/blockdev.h index a86d99b..3b5fcda 100644 --- a/include/sysemu/blockdev.h +++ b/include/sysemu/blockdev.h @@ -35,6 +35,7 @@ struct DriveInfo { bool is_default; /* Added by default_drive() ? */ int media_cd; QemuOpts *opts; + bool claimed_by_board; QTAILQ_ENTRY(DriveInfo) next; }; @@ -45,6 +46,7 @@ BlockBackend *blk_by_legacy_dinfo(DriveInfo *dinfo); void override_max_devs(BlockInterfaceType type, int max_devs); DriveInfo *drive_get(BlockInterfaceType type, int bus, int unit); +void drive_mark_claimed_by_board(void); void drive_check_orphaned(void); DriveInfo *drive_get_by_index(BlockInterfaceType type, int index); int drive_get_max_bus(BlockInterfaceType type); -- cgit v1.1
