We're now finally emulating an s390x CPU, so we can move quite some logic from the kvm code out into generic CPU code. This patch does this and adjusts the interfaces according to what the code around now expects to be able to call. Signed-off-by: NAlexander Graf <agraf@suse.de>

There are some instructions that can't (or shouldn't) be expressed by pure tcg code. For those, we call into externally compiled C functions. This patch implements those C functions. Signed-off-by: NAlexander Graf <agraf@suse.de>

When running system emulation, we need to transverse through the MMU and deliver interrupts according to the specification. This patch implements those two pieces and in addition adjusts the CPU initialization code to account for the new fields in CPUState. Signed-off-by: NAlexander Graf <agraf@suse.de>

The default reset handler does a memset(0) until right in between CPU_COMMON. I incorrectly changed that behavior on the s390x port, so let's move the fields in CPUState around to reflect the correct split up to which point memset(0) zeros out everything.

The s390x virtio bus keeps management information on virtio after the top of the guest's RAM. We need to be able to tell the guest the size of its RAM (without virtio stuff), but also be able to trap when the guest accesses RAM outside of its scope (including virtio stuff). So we need a variable telling us the size of the virtio stuff, so we can calculate the highest available RAM address from that. While at it, also increase the maximum number of virtio pages, so we play along well with more recent kernels that spawn a ridiculous number of virtio console adapters.

Currently smp support for kvm does not work. Qemu does a kvm run even on secondary CPUs which dont have a sane state (initial psw == 0) triggering some program faults. Architecturally these cpus are in the stopped state, so we should not do the kvm run ioctl. (these CPUs will be started by a SIGP restart later during the boot process) We need to tell the loop that this cpu should not run. Jan Kiszka pointed out that kvm_arch_process_async_events is the right place to do. Signed-off-by: NChristian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: NAlexander Graf <agraf@suse.de>

AHCI provides two ways of reading/writing data: 1) NCQ 2) ATA commands with the LBA in the command FIS In the second code path, we didn't handle any LBAs that were bigger than 16 bits, so whenever a guest that used high LBA numbers wanted to access data, the LBA got truncated down to 16 bits, giving the guest garbage. This patch adds support for LBAs higher than 16 bits. I've tested that it works just fine with SeaBIOS and Linux guests. This patch also unbreaks the often reported grub errors people have seen with AHCI. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

DriveInfo is closely tied to -drive, and like -drive, it mixes information about host and guest part of the block device. Unlike DriveInfo, BlockDriverState should be about the host part only. One of the remaining guest bits there is the "type hint". -drive option media sets it, and qdevs "ide-drive", "scsi-disk" and non-qdev IF_XEN devices check it to pick HD vs. CD. Communicate -drive option media via new DriveInfo member media_cd instead. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

query-block's specification documents response member "type" with values "hd", "cdrom", "floppy", "unknown". Its value is unreliable: a block device used as floppy has type "floppy" if created with if=floppy, but type "hd" if created with if=none. That's because with if=none, the type is at best a declaration of intent: the drive can be connected to any guest device. Its type is really the guest device's business. Reporting it here is wrong. No known user of QMP uses "type". It's unlikely that any unknown users exist, because its value is useless unless you know how the block device was created. But then you also know the true value. Fixing the broken value risks breaking (hypothetical!) clients that somehow rely on the current behavior. Not fixing the value risks breaking (hypothetical!) clients that rely on the value to be accurate. Can't entirely avoid hypothetical lossage. Change the value to be always "unknown". This makes "info block" always report "type=unknown". Pointless. Change it to not report the type. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

A "scsi-disk" is either a hard disk or a CD-ROM, depending on the associated BlockDriverState's type hint. Unclean; disk vs. CD belongs to the guest part, not the host part. Have separate qdevs "scsi-hd" and "scsi-cd" to model disk vs. CD in the guest part. Keep scsi-disk for backward compatibility. Don't copy scsi-disk property removable to scsi-cd. It's not used and always zero(!) there. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Have separate qdevs "ide-hd" and "ide-cd" to model disk vs. CD in the guest part. Keep ide-drive for backward compatibility. "ide-disk" would perhaps be a nicer name than "ide-hd", but there's already "scsi-disk", which is like "ide-drive", and will be likewise split in the next commit. {ide,scsi}-{hd,cd} is the best consistent set of names I could find within the backward compatibility straightjacket.

One strategy to limit the startup delay of consistency check when opening image files is to ensure that the file is marked dirty for as little time as possible. QED currently marks the image dirty when the first allocating write request is issued and clears the dirty bit again when the image is cleanly closed. In practice that means the image is marked dirty for most of a guest's lifetime and prone to being in a dirty state upon crash or power failure. It is safe to clear the dirty bit after all allocating write requests have completed and a flush has been performed. This patch adds a timer after the last allocating write request completes. When the timer fires it will flush and then clear the dirty bit. The timer is set to 5 seconds and is cancelled upon arrival of a new allocating write request.

A thread should only be counted as idle when it really is waiting for new requests. Without this patch, sometimes too few threads are started as busy threads are counted as idle.
