Voiding the ITS caches is not supposed to happen via individual register writes. So we introduced a dedicated ITS KVM device ioctl to perform a cold reset of the ITS: KVM_DEV_ARM_VGIC_GRP_CTRL/KVM_DEV_ARM_ITS_CTRL_RESET. Let's use this latter if the kernel supports it.

At the moment the ITS is not properly reset and this causes various bugs on save/restore. We implement a minimalist reset through individual register writes but for kernel versions before v4.15 this fails voiding the vITS cache. We cannot claim we have a comprehensive reset (hence the error message) but that's better than nothing.

The refactoring of commit 296e5a0a has a nasty bug: it accidentally dropped the generation of code to raise the UNDEF exception when disas_thumb2_insn() returns nonzero. This means that 32-bit Thumb2 instruction patterns that ought to UNDEF just act like nops instead. This is likely to break any number of things, including the kernel's "disable the FPU and use the UNDEF exception to identify when to turn it back on again" trick.

Commit 5c0919d0 ("virtio-scsi: Add virtqueue_size parameter allowing virtqueue size to be set.") introduced a new parameter to virtio-scsi. Later, commit 92003610 ("vhost-user-scsi: add missing virtqueue_size param") added that parameter to the new vhost-user-scsi interface but neglected the existing vhost-scsi interface it was built on. Apply the same change to vhost-scsi, so that we can boot a guest with a device defined. This also avoids crashing a guest when hotplugging a vhost-scsi device.

Occasionally in Linux guests on x86_64 we're seeing logs like: ppc_set_irq: 0x55b4e0d562f0 n_IRQ 8 level 1 => pending 00000100req 00000004 when they should read: ppc_set_irq: 0x55b4e0d562f0 n_IRQ 8 level 1 => pending 00000100req 00000002 The "00000004" is CPU_INTERRUPT_EXITTB yet the code calls cpu_interrupt(cs, CPU_INTERRUPT_HARD) ("00000002") in this function just before the log message. Something is causing the HARD bit setting to get lost. The knock on effect of losing that bit is the decrementer timer interrupts don't get delivered which causes the guest to sit idle in its idle handler and 'hang'. The issue occurs due to races from code which sets CPU_INTERRUPT_EXITTB. Rather than poking directly into cs->interrupt_request, that code needs to: a) hold BQL b) use the cpu_interrupt() helper This patch fixes the call sites to do this, fixing the hang. The calls are made from a variety of contexts so a helper function is added to handle the necessary locking. This can likely be improved and optimised in the future but it ensures the code is correct and doesn't lockup as it stands today.

Starting from commit 40840e41 we are pausing all block jobs during bdrv_reopen_multiple() to prevent any of them from finishing and removing nodes from the graph while they are being reopened. It turns out that pausing a block job doesn't necessarily prevent it from finishing: a paused block job can still run its exit function from the main loop and call block_job_completed(). The mirror block job in particular always goes to the main loop while it is paused (by virtue of the bdrv_drained_begin() call in mirror_run()). Destroying a paused block job during bdrv_reopen_multiple() has two consequences: 1) The references to the nodes involved in the job are released, possibly destroying some of them. If those nodes were in the reopen queue this would trigger the problem originally described in commit 40840e41, crashing QEMU. 2) At the end of bdrv_reopen_multiple(), bdrv_drain_all_end() would not be doing all necessary bdrv_parent_drained_end() calls. I can reproduce problem 1) easily with iotest 030 by increasing STREAM_BUFFER_SIZE from 512KB to 8MB in block/stream.c, or by tweaking the iotest like in this example: https://lists.gnu.org/archive/html/qemu-block/2017-11/msg00934.html This patch keeps an additional reference to all block jobs between block_job_pause_all() and block_job_resume_all(), guaranteeing that they are kept alive.

At guest reset time, we allocate a hash page table (HPT) for the guest based on the guest's RAM size. If dynamic HPT resizing is not available we use the maximum RAM size, if it is we use the current RAM size. But the "current RAM size" calculation is incorrect - we just use the "base" ram_size from the machine structure. This doesn't include any pluggable DIMMs that are already plugged at reset time. This means that if you try to start a 'pseries' machine with a DIMM specified on the command line that's much larger than the "base" RAM size, then the guest will get a woefully inadequate HPT. This can lead to a guest freeze during boot as it runs out of HPT space during initial MMU setup.

Since commit f1f9e6c5 "vhost: adapt vhost_verify_ring_mappings() to virtio 1 ring layout", we check the mapping of each part (descriptor table, available ring and used ring) of each virtqueue separately. The checking of a part is done by the vhost_verify_ring_part_mapping() function: it returns either 0 on success or a negative errno if the part cannot be mapped at the same place. Unfortunately, the vhost_verify_ring_mappings() function checks its return value the other way round. It means that we either: - only verify the descriptor table of the first virtqueue, and if it is valid we ignore all the other mappings - or ignore all broken mappings until we reach a valid one ie, we only raise an error if all mappings are broken, and we consider all mappings are valid otherwise (false success), which is obviously wrong. This patch ensures that vhost_verify_ring_mappings() only returns success if ALL mappings are okay.

Migration of pseries is broken with TCG because QEMU tries to restore KVM MMU state unconditionally. The result is a SIGSEGV in kvm_vm_ioctl(): #0 kvm_vm_ioctl (s=0x0, type=-2146390353) at qemu/accel/kvm/kvm-all.c:2032 #1 0x00000001003e3e2c in kvmppc_configure_v3_mmu (cpu=<optimized out>, radix=<optimized out>, gtse=<optimized out>, proc_tbl=<optimized out>) at qemu/target/ppc/kvm.c:396 #2 0x00000001002f8b88 in spapr_post_load (opaque=0x1019103c0, version_id=<optimized out>) at qemu/hw/ppc/spapr.c:1578 #3 0x000000010059e4cc in vmstate_load_state (f=0x106230000, vmsd=0x1009479e0 <vmstate_spapr>, opaque=0x1019103c0, version_id=<optimized out>) at qemu/migration/vmstate.c:165 #4 0x00000001005987e0 in vmstate_load (f=<optimized out>, se=<optimized out>) at qemu/migration/savevm.c:748 This patch fixes the problem by not calling the KVM function with the TCG mode.
