We try the drive defined with -drive if=ide,index=0 (or equivalent sugar). We use it only if (dinfo && bdrv_is_inserted(dinfo->bdrv) && !bdrv_is_removable(dinfo->bdrv)). This is a convoluted way to test for "drive media can't be removed". The only way to create such a drive with -drive if=ide is media=cdrom. And that sets dinfo->media_cd, so just test that.

savevm and loadvm silently ignore block devices with removable media, such as floppies and SD cards. Rolling back a VM to a previous checkpoint will *not* roll back writes to block devices with removable media. Moreover, bdrv_is_removable() is a confused mess, and wrong in at least one case: it considers "-drive if=xen,media=cdrom -M xenpv" removable. It'll be cleaned up later in this series. Read-only block devices are also ignored, but that's okay. Fix by ignoring only read-only block devices and empty block devices.

Change (!bdrv_is_removable(bs) || bdrv_is_inserted(bs)) to just bdrv_is_inserted(). Rationale: The value of bdrv_is_removable(bs) matters only when bdrv_is_inserted(bs) is false. bdrv_is_inserted(bs) is true when bs is open (bs->drv != NULL) and not an empty host drive (CD-ROM or floppy). Therefore, bdrv_is_removable(bs) matters only when: 1. bs is not open old: may call bdrv_flush(bs), which does nothing new: won't call 2. bs is an empty host drive old: may call bdrv_flush(bs), which calls driver method raw_flush(), which calls fdatasync() or equivalent, which can't do anything useful while the drive is empty new: won't call Result is bs->drv && !bdrv_is_read_only(bs) && bdrv_is_inserted(bs). bdrv_is_inserted(bs) implies bs->drv. Drop the redundant test. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

fdctrl_change_cb() gets called on a virtual media change via monitor. It would be nice if host device block drivers called it on physical media change, but they don't. bdrv_media_changed() lets you poll for media change, but it returns "don't know" except with block driver "host_floppy". FDrive member media_changed gets set on device initialization and by fdctrl_change_cb(), and cleared by fdctrl_media_changed(). Thus, it's set on first entry to fdctrl_media_changed() since device initialization or virtual media change. fdctrl_media_changed() ignores media_changed unless bdrv_media_changed() returns "don't know". If we change media via monitor (setting media_changed), and the new media's block driver returns 0, we lose. Fortunately, "host_floppy" always returns 1 on first call. Brittle. Clean it up not to rely on it. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Block driver "raw" forwards most methods to the underlying block driver. However, it doesn't implement method bdrv_media_changed(). Makes bdrv_media_changed() always return -ENOTSUP. I believe -fda /dev/fd0 gives you raw over host_floppy, and disk change detection (fdc register 7 bit 7) is broken. Testing my theory requires a computer museum, though.

For now, this just protects against programming errors like having the same drive back multiple non-qdev devices, or untimely bdrv_delete(). Later commits will add other interesting uses.

qemu may segfault when a BH handler first deletes a BH and then (possibly indirectly) calls a nested qemu_bh_poll(). This is because the inner instance frees the BH and deletes it from the list that the outer one processes. This patch deletes BHs only in the outermost qemu_bh_poll instance. Commit 7887f620 already tried to achieve the same, but it assumed that the BH handler would only delete its own BH. With a nested qemu_bh_poll(), this isn't guaranteed, so that commit wasn't enough. Hope this one fixes it for real. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

A packed struct needs different gcc attributes for compilations with MinGW compilers because glib-2.0 adds compiler flag -mms-bitfields which modifies the packing algorithm. Attribute gcc_struct reverses the negative effects of -mms-bitfields. QEMU_PACKED sets this attribute and must be used for any packed struct which is affected by -mms-bitfields.

Enabling the I/O thread by default seems like an important part of declaring 1.0. Besides allowing true SMP support with KVM, the I/O thread means that the TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which currently requires a (racey) signal based alarm system. I know there have been concerns about performance. I think so far the ones that have come up (virtio-net) are most likely due to secondary reasons like decreased batching. I think we ought to force enabling I/O thread early in 1.0 development and commit to resolving any lingering issues. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This patch changes qemu_set_fd_handler to be implemented in terms of g_io_add_watch(). The semantics are a bit different so some glue is required. qemu_set_fd_handler2 is much harder to convert because of its use of polling. The glib main loop has the major of advantage of having a proven thread safe architecture. By using the glib main loop instead of our own, it will allow us to eventually introduce multiple I/O threads. I'm pretty sure that this will work on Win32, but I would appreciate some help testing. I think the semantics of g_io_channel_unix_new() are really just tied to the notion of a "unix fd" and not necessarily unix itself. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This allows GSources to be used to register callback events in QEMU. This is useful as it allows us to take greater advantage of glib and also because it allows us to write code that is more easily testable outside of QEMU since we can make use of glib's main loop in unit tests. All new code should use glib's callback mechanisms for registering fd events which are very well documented at: http://developer.gnome.org/glib/stable/glib-The-Main-Event-Loop.html And: http://developer.gnome.org/gio/stable/Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
