* HostMem: Add mechanism to opt in kvm guest memfd via MachineStateXiaoyao Li2024-04-232-0/+3
| | | | | | | | | | | | | | | | | Add a new member "guest_memfd" to memory backends. When it's set to true, it enables RAM_GUEST_MEMFD in ram_flags, thus private kvm guest_memfd will be allocated during RAMBlock allocation. Memory backend's @guest_memfd is wired with @require_guest_memfd field of MachineState. It avoid looking up the machine in phymem.c. MachineState::require_guest_memfd is supposed to be set by any VMs that requires KVM guest memfd as private memory, e.g., TDX VM.

* RAMBlock: Add support of KVM private guest memfdXiaoyao Li2024-04-234-4/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | Add KVM guest_memfd support to RAMBlock so both normal hva based memory and kvm guest memfd based private memory can be associated in one RAMBlock. Introduce new flag RAM_GUEST_MEMFD. When it's set, it calls KVM ioctl to create private guest_memfd during RAMBlock setup. Allocating a new RAM_GUEST_MEMFD flag to instruct the setup of guest memfd is more flexible and extensible than simply relying on the VM type because in the future we may have the case that not all the memory of a VM need guest memfd. As a benefit, it also avoid getting MachineState in memory subsystem. Note, RAM_GUEST_MEMFD is supposed to be set for memory backends of confidential guests, such as TDX VM. How and when to set it for memory backends will be implemented in the following patches. Introduce memory_region_has_guest_memfd() to query if the MemoryRegion has KVM guest_memfd allocated.

* kvm: Introduce support for memory_attributesXiaoyao Li2024-04-231-0/+4
| | | | | | | | | | | | | Introduce the helper functions to set the attributes of a range of memory to private or shared. This is necessary to notify KVM the private/shared attribute of each gpa range. KVM needs the information to decide the GPA needs to be mapped at hva-based shared memory or guest_memfd based private memory.

* KVM: remove kvm_arch_cpu_check_are_resettablePaolo Bonzini2024-04-231-10/+0
| | | | | | | | | | Board reset requires writing a fresh CPU state. As far as KVM is concerned, the only thing that blocks reset is that CPU state is encrypted; therefore, kvm_cpus_are_resettable() can simply check if that is the case.

* KVM: track whether guest state is encryptedPaolo Bonzini2024-04-232-0/+3
| | | | | | | | | | | | | | | | | | | So far, KVM has allowed KVM_GET/SET_* ioctls to execute even if the guest state is encrypted, in which case they do nothing. For the new API using VM types, instead, the ioctls will fail which is a safer and more robust approach. The new API will be the only one available for SEV-SNP and TDX, but it is also usable for SEV and SEV-ES. In preparation for that, require architecture-specific KVM code to communicate the point at which guest state is protected (which must be after kvm_cpu_synchronize_post_init(), though that might change in the future in order to suppor migration). From that point, skip reading registers so that cpu->vcpu_dirty is never true: if it ever becomes true, kvm_arch_put_registers() will fail miserably.

Currently each of them exposes individual *_kvm_init() functions and let machine code or kvm code to call it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already attempted to set and clear can_do_io before the first and last insns, but only used the initial value of max_insns and the call to translator_io_start to find those insns. Now that we track insn_start in DisasContextBase, and now that we have emit_before_op, we can wait until we have finished translation to identify the true first and last insns and emit the sets of can_do_io at that time. This fixes the case of a translation block which crossed a page boundary, and for which the second page turned out to be mmio. In this case we truncate the block, and the previous logic for can_do_io could leave a block with a single insn with can_do_io set to false, which would fail an assertion in cpu_io_recompile.

* virtio-snd: rewrite invalid tx/rx message handlingManos Pitsidianakis2024-04-091-1/+15
| | | | | | | | | | | | | | | | | | | | | The current handling of invalid virtqueue elements inside the TX/RX virt queue handlers is wrong. They are added in a per-stream invalid queue to be processed after the handler is done examining each message, but the invalid message might not be specifying any stream_id; which means it's invalid to add it to any stream->invalid queue since stream could be NULL at this point. This commit moves the invalid queue to the VirtIOSound struct which guarantees there will always be a valid temporary place to store them inside the tx/rx handlers. The queue will be emptied before the handler returns, so the queue must be empty at any other point of the device's lifetime.

* Revert "tap: setting error appropriately when calling net_init_tap_one()"Akihiko Odaki2024-03-291-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 46d4d36d0bf2b24b205f2f604f0905db80264eef. The reverted commit changed to emit warnings instead of errors when vhost is requested but vhost initialization fails if vhostforce option is not set. However, vhostforce is not meant to ignore vhost errors. It was once introduced as an option to commit 5430a28fe4 ("vhost: force vhost off for non-MSI guests") to force enabling vhost for non-MSI guests, which will have worse performance with vhost. The option was deprecated with commit 1e7398a140 ("vhost: enable vhost without without MSI-X") and changed to behave identical with the vhost option for compatibility. Worse, commit bf769f742c ("virtio: del net client if net_init_tap_one failed") changed to delete the client when vhost fails even when the failure only results in a warning. The leads to an assertion failure for the -netdev command line option. The reverted commit was intended to avoid that the vhost initialization failure won't result in a corrupted netdev. This problem should have been fixed by deleting netdev when the initialization fails instead of ignoring the failure with an arbitrary option. Fortunately, commit bf769f742c ("virtio: del net client if net_init_tap_one failed"), mentioned earlier, implements this behavior. Restore the correct semantics and fix the assertion failure for the -netdev command line option by reverting the problematic commit.

| * aspeed/smc: Only wire flash devices at resetCédric Le Goater2024-03-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Aspeed machines have many Static Memory Controllers (SMC), up to 8, which can only drive flash memory devices. Commit 27a2c66c92ec ("aspeed/smc: Wire CS lines at reset") tried to ease the definitions of these devices by allowing flash devices from the command line to be attached to a SSI bus. For that, the wiring of the CS lines of the Aspeed SMC controller was moved at reset. Two assumptions are made though, first that the device has a SSI_GPIO_CS GPIO line, which is not always the case, and second that it is a flash device. Correct this problem by ensuring that the devices attached to the bus are of the correct flash type. This fixes a QEMU abort when devices without a CS line, such as the max111x, are passed on the command line. While at it, export TYPE_M25P80 used in the Xilinx Versal Virtual machine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | legacy mode doesn't support structures of type 2 and more, and CLI has a check for '-smbios type' option, however it's still possible to sneak in type4 as a blob with '-smbios file' option. However doing the later makes SMBIOS tables broken since SeaBIOS doesn't expect that. Rather than trying to add support for type4 to legacy code (both QEMU and SeaBIOS), simplify smbios_get_table_legacy() by dropping not relevant check in legacy code and error out on type4 blob.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling job_pause_point() while holding the graph reader lock potentially results in a deadlock: bdrv_graph_wrlock() first drains everything, including the mirror job, which pauses it. The job is only unpaused at the end of the drain section, which is when the graph writer lock has been successfully taken. However, if the job happens to be paused at a pause point where it still holds the reader lock, the writer lock can't be taken as long as the job is still paused. Mark job_pause_point() as GRAPH_UNLOCKED and fix mirror accordingly.

This can result in stores though the TCG TLB not setting the dirty memory bitmap and ultimately causes memory corruption / lost updates during migration from a TCG host.

Forgot those in updating the structure definition but did include them in the size define leading to a buffer overrun. Also use the define so that we don't duplicate the value. Fixes: Coverity ID 1534095 buffer overrun Fixes: 8700ee15de ("hw/cxl: Standardize all references on CXL r3.1 and minor updates") Reported-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Message-Id: <20240308143831.6256-1-Jonathan.Cameron@huawei.com> Reviewed-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | aw-bits is a new option that allows to set the bit width of the input address range. This value will be used as a default for the device config input_range.end. By default it is set to 64 bits which is the current value.

Current page size mask default is qemu_target_page_mask so this translates into a 4k granule on ARM and x86_64 where virtio-iommu is supported.
