2024-02-20target/i386: Generate an illegal opcode exception on cmp instructions with ↵Ziqiao Kong
lock prefix target/i386: As specified by Intel Manual Vol2 3-180, cmp instructions are not allowed to have lock prefix and a `UD` should be raised. Without this patch, s1->T0 will be uninitialized and used in the case OP_CMPL.

2024-02-20i386/cpuid: Move leaf 7 to correct groupXiaoyao Li
CPUID leaf 7 was grouped together with SGX leaf 0x12 by commit b9edbadefb9e ("i386: Propagate SGX CPUID sub-leafs to KVM") by mistake. SGX leaf 0x12 has its specific logic to check if subleaf (starting from 2) is valid or not by checking the bit 0:3 of corresponding EAX is 1 or not. Leaf 7 follows the logic that EAX of subleaf 0 enumerates the maximum valid subleaf.

2024-02-16.gitlab-ci/windows.yml: Don't install libusb or spice packages on 32-bitPeter Maydell
When msys2 updated their libusb packages to libusb 1.0.27, they dropped support for building them for mingw32, leaving only mingw64 packages. This broke our CI job, as the 'pacman' package install now fails with: error: target not found: mingw-w64-i686-libusb error: target not found: mingw-w64-i686-usbredir (both these binary packages are from the libusb source package). Similarly, spice is now 64-bit only: error: target not found: mingw-w64-i686-spice Fix this by dropping these packages from the list we install for our msys2-32bit build. We do this with a simple mechanism for the msys2-64bit and msys2-32bit jobs to specify a list of extra packages to install on top of the common ones we install for both jobs.

2024-02-16iotests: Make 144 deterministic againKevin Wolf
Since commit effd60c8 changed how QMP commands are processed, the order of the block-commit return value and job events in iotests 144 wasn't fixed and more and caused the test to fail intermittently. Change the test to cache events first and then print them in a predefined order.

Avoid the assertion by not calling arm_mdcr_el2_eff() before we have done the early return for "PMU not present".

2024-02-15hw/i386: Fix _STA return value for ACPI0017Jonathan Cameron
Found whilst testing a series for the linux kernel that actually bothers to check if enabled is set. 0xB is the option used for vast majority of DSDT entries in QEMU. It is a little odd for a device that doesn't really exist and is simply a hook to tell the OS there is a CEDT table but 0xB seems a reasonable choice and avoids need to special case this device in the OS. Means: * Device present. * Device enabled and decoding it's resources. * Not shown in UI * Functioning properly * No battery (on this device!)

2024-02-14hw/cxl/device: read from register values in mdev_reg_read()Hyeonggon Yoo
In the current mdev_reg_read() implementation, it consistently returns that the Media Status is Ready (01b). This was fine until commit 25a52959f99d ("hw/cxl: Add support for device sanitation") because the media was presumed to be ready. However, as per the CXL 3.0 spec "8.2.9.8.5.1 Sanitize (Opcode 4400h)", during sanitation, the Media State should be set to Disabled (11b). The mentioned commit correctly sets it to Disabled, but mdev_reg_read() still returns Media Status as Ready. To address this, update mdev_reg_read() to read register values instead of returning dummy values. Note that __toggle_media() managed to not only write something that no one read, it did it to the wrong register storage and so changed the reported mailbox size which was definitely not the intent. That gets fixed as a side effect of allocating separate state storage for this register.

This was previously not seen because the length of the CDAT data was less than 256 thus resulting in an equivalent checksum value. Properly calculate the checksum for the CDAT header.

2024-02-14hw/net/tulip: add chip status register valuesSven Schnelle
Netbsd isn't able to detect a link on the emulated tulip card. That's because netbsd reads the Chip Status Register of the Phy (address 0x14). The default phy data in the qemu tulip driver is all zero, which means no link is established and autonegotation isn't complete. Therefore set the register to 0x3b40, which means: Link is up, Autonegotation complete, Full Duplex, 100MBit/s Link speed. Also clear the mask because this register is read only.

2024-02-12virtio-blk: avoid using ioeventfd state in irqfd conditionalStefan Hajnoczi
Requests that complete in an IOThread use irqfd to notify the guest while requests that complete in the main loop thread use the traditional qdev irq code path. The reason for this conditional is that the irq code path requires the BQL: if (s->ioeventfd_started && !s->ioeventfd_disabled) { virtio_notify_irqfd(vdev, req->vq); } else { virtio_notify(vdev, req->vq); } There is a corner case where the conditional invokes the irq code path instead of the irqfd code path: static void virtio_blk_stop_ioeventfd(VirtIODevice *vdev) { ... /* * Set ->ioeventfd_started to false before draining so that host notifiers * are not detached/attached anymore. */ s->ioeventfd_started = false; /* Wait for virtio_blk_dma_restart_bh() and in flight I/O to complete */ blk_drain(s->conf.conf.blk); During blk_drain() the conditional produces the wrong result because ioeventfd_started is false. Use qemu_in_iothread() instead of checking the ioeventfd state.

2024-02-12virtio: Re-enable notifications after drainHanna Czenczek
During drain, we do not care about virtqueue notifications, which is why we remove the handlers on it. When removing those handlers, whether vq notifications are enabled or not depends on whether we were in polling mode or not; if not, they are enabled (by default); if so, they have been disabled by the io_poll_start callback. Because we do not care about those notifications after removing the handlers, this is fine. However, we have to explicitly ensure they are enabled when re-attaching the handlers, so we will resume receiving notifications. We do this in virtio_queue_aio_attach_host_notifier*(). If such a function is called while we are in a polling section, attaching the notifiers will then invoke the io_poll_start callback, re-disabling notifications. Because we will always miss virtqueue updates in the drained section, we also need to poll the virtqueue once after attaching the notifiers.

2024-02-12virtio-scsi: Attach event vq notifier with no_pollHanna Czenczek
As of commit 38738f7dbbda90fbc161757b7f4be35b52205552 ("virtio-scsi: don't waste CPU polling the event virtqueue"), we only attach an io_read notifier for the virtio-scsi event virtqueue instead, and no polling notifiers. During operation, the event virtqueue is typically non-empty, but none of the buffers are intended to be used immediately. Instead, they only get used when certain events occur. Therefore, it makes no sense to continuously poll it when non-empty, because it is supposed to be and stay non-empty. We do this by using virtio_queue_aio_attach_host_notifier_no_poll() instead of virtio_queue_aio_attach_host_notifier() for the event virtqueue. Commit 766aa2de0f29b657148e04599320d771c36fd126 ("virtio-scsi: implement BlockDevOps->drained_begin()") however has virtio_scsi_drained_end() use virtio_queue_aio_attach_host_notifier() for all virtqueues, including the event virtqueue.

2024-02-09pci-host: designware: Limit value range of iATU viewport registerGuenter Roeck
The latest version of qemu (v8.2.0-869-g7a1dc45af5) crashes when booting the mcimx7d-sabre emulation with Linux v5.11 and later. qemu-system-arm: ../system/memory.c:2750: memory_region_set_alias_offset: Assertion `mr->alias' failed. Problem is that the Designware PCIe emulation accepts the full value range for the iATU Viewport Register. However, both hardware and emulation only support four inbound and four outbound viewports. The Linux kernel determines the number of supported viewports by writing 0xff into the viewport register and reading the value back. The expected value when reading the register is the highest supported viewport index. Match that code by masking the supported viewport value range when the register is written. With this change, the Linux kernel reports imx6q-pcie 33800000.pcie: iATU: unroll F, 4 ob, 4 ib, align 0K, limit 4G as expected and supported.

2024-02-09system/vl.c: Fix handling of '-serial none -serial something'Peter Maydell
Currently if the user passes multiple -serial options on the command line, we mostly treat those as applying to the different serial devices in order, so that for example -serial stdio -serial file:filename will connect the first serial port to stdio and the second to the named file. The exception to this is the '-serial none' serial device type. This means "don't allocate this serial device", but a bug means that following -serial options are not correctly handled, so that -serial none -serial stdio has the unexpected effect that stdio is connected to the first serial port, not the second. This is a very long-standing bug that dates back at least as far as commit 998bbd74b9d81 from 2009. Make the 'none' serial type move forward in the indexing of serial devices like all the other serial types, so that any subsequent -serial options are correctly handled. Note that if your commandline mistakenly had a '-serial none' that was being overridden by a following '-serial something' option, you should delete the unnecessary '-serial none'. This will give you the same behaviour as before, on QEMU versions both with and without this bug fix.
