2022-12-15s390x/pci: reset ISM passthrough devices on shutdown and system resetMatthew Rosato
ISM device firmware stores unique state information that can can cause a wholesale unmap of the associated IOMMU (e.g. when we get a termination signal for QEMU) to trigger firmware errors because firmware believes we are attempting to invalidate entries that are still in-use by the guest OS (when in fact that guest is in the process of being terminated or rebooted). To alleviate this, register both a shutdown notifier (for unexpected termination cases e.g. virsh destroy) as well as a reset callback (for cases like guest OS reboot). For each of these scenarios, trigger PCI device reset; this is enough to indicate to firmware that the IOMMU is no longer in-use by the guest OS, making it safe to invalidate any associated IOMMU entries.

2022-12-15s390x/pci: shrink DMA aperture to be bound by vfio DMA limitMatthew Rosato
Currently, s390x-pci performs accounting against the vfio DMA limit and triggers the guest to clean up mappings when the limit is reached. Let's go a step further and also limit the size of the supported DMA aperture reported to the guest based upon the initial vfio DMA limit reported for the container (if less than than the size reported by the firmware/host zPCI layer). This avoids processing sections of the guest DMA table during global refresh that, for common use cases, will never be used anway, and makes exhausting the vfio DMA limit due to mismatch between guest aperture size and host limit far less likely and more indicitive of an error.

2022-12-15hw/arm: Convert TYPE_ARM_SMMUV3 to 3-phase resetPeter Maydell
Convert the TYPE_ARM_SMMUV3 device to 3-phase reset. The legacy reset method doesn't do anything that's invalid in the hold phase, so the conversion only requires changing it to a hold phase method, and using the 3-phase versions of the "save the parent reset method and chain to it" code.

2022-12-15hw/arm/virt: Add 'compact-highmem' propertyGavin Shan
After the improvement to high memory region address assignment is applied, the memory layout can be changed, introducing possible migration breakage. For example, VIRT_HIGH_PCIE_MMIO memory region is disabled or enabled when the optimization is applied or not, with the following configuration. The configuration is only achievable by modifying the source code until more properties are added to allow users selectively disable those high memory regions. pa_bits = 40; vms->highmem_redists = false; vms->highmem_ecam = false; vms->highmem_mmio = true; # qemu-system-aarch64 -accel kvm -cpu host \ -machine virt-7.2,compact-highmem={on, off} \ -m 4G,maxmem=511G -monitor stdio Region compact-highmem=off compact-highmem=on ---------------------------------------------------------------- MEM [1GB 512GB] [1GB 512GB] HIGH_GIC_REDISTS2 [512GB 512GB+64MB] [disabled] HIGH_PCIE_ECAM [512GB+256MB 512GB+512MB] [disabled] HIGH_PCIE_MMIO [disabled] [512GB 1TB] In order to keep backwords compatibility, we need to disable the optimization on machine, which is virt-7.1 or ealier than it. It means the optimization is enabled by default from virt-7.2. Besides, 'compact-highmem' property is added so that the optimization can be explicitly enabled or disabled on all machine types by users.

2022-12-15hw/arm/virt: Improve high memory region address assignmentGavin Shan
There are three high memory regions, which are VIRT_HIGH_REDIST2, VIRT_HIGH_PCIE_ECAM and VIRT_HIGH_PCIE_MMIO. Their base addresses are floating on highest RAM address. However, they can be disabled in several cases. (1) One specific high memory region is likely to be disabled by code by toggling vms->highmem_{redists, ecam, mmio}. (2) VIRT_HIGH_PCIE_ECAM region is disabled on machine, which is 'virt-2.12' or ealier than it. (3) VIRT_HIGH_PCIE_ECAM region is disabled when firmware is loaded on 32-bits system. (4) One specific high memory region is disabled when it breaks the PA space limit. The current implementation of virt_set_{memmap, high_memmap}() isn't optimized because the high memory region's PA space is always reserved, regardless of whatever the actual state in the corresponding vms->highmem_{redists, ecam, mmio} flag. In the code, 'base' and 'vms->highest_gpa' are always increased for case (1), (2) and (3). It's unnecessary since the assigned PA space for the disabled high memory region won't be used afterwards. Improve the address assignment for those three high memory region by skipping the address assignment for one specific high memory region if it has been disabled in case (1), (2) and (3). The memory layout may be changed after the improvement is applied, which leads to potential migration breakage. So 'vms->highmem_compact' is added to control if the improvement should be applied. For now, 'vms->highmem_compact' is set to false, meaning that we don't have memory layout change until it becomes configurable through property 'compact-highmem' in next patch.

2022-12-01vhost: enable vrings in vhost_dev_start() for vhost-user devicesStefano Garzarella
Commit 02b61f38d3 ("hw/virtio: incorporate backend features in features") properly negotiates VHOST_USER_F_PROTOCOL_FEATURES with the vhost-user backend, but we forgot to enable vrings as specified in docs/interop/vhost-user.rst: If ``VHOST_USER_F_PROTOCOL_FEATURES`` has not been negotiated, the ring starts directly in the enabled state. If ``VHOST_USER_F_PROTOCOL_FEATURES`` has been negotiated, the ring is initialized in a disabled state and is enabled by ``VHOST_USER_SET_VRING_ENABLE`` with parameter 1. Some vhost-user front-ends already did this by calling vhost_ops.vhost_set_vring_enable() directly: - backends/cryptodev-vhost.c - hw/net/virtio-net.c - hw/virtio/vhost-user-gpio.c But most didn't do that, so we would leave the vrings disabled and some backends would not work. We observed this issue with the rust version of virtiofsd [1], which uses the event loop [2] provided by the vhost-user-backend crate where requests are not processed if vring is not enabled. Let's fix this issue by enabling the vrings in vhost_dev_start() for vhost-user front-ends that don't already do this directly. Same thing also in vhost_dev_stop() where we disable vrings.

2022-11-21hw/sd: Fix sun4i allwinner-sdhost for U-BootStrahinja Jankovic
Trying to run U-Boot for Cubieboard (Allwinner A10) fails because it cannot access SD card. The problem is that FIFO register in current allwinner-sdhost implementation is at the address corresponding to Allwinner H3, but not A10. Linux kernel is not affected since Linux driver uses DMA access and does not use FIFO register for reading/writing. This patch adds new class parameter `is_sun4i` and based on that parameter uses register at offset 0x100 either as FIFO register (if sun4i) or as threshold register (if not sun4i; in this case register at 0x200 is FIFO register). Tested with U-Boot and Linux kernel image built for Cubieboard and OrangePi PC.

2022-11-07hw/virtio: introduce virtio_device_should_startAlex Bennée
The previous fix to virtio_device_started revealed a problem in its use by both the core and the device code. The core code should be able to handle the device "starting" while the VM isn't running to handle the restoration of migration state. To solve this duel use introduce a new helper for use by the vhost-user backends who all use it to feed a should_start variable. We can also pick up a change vhost_user_blk_set_status while we are at it which follows the same pattern.

2022-11-07hw/smbios: add core_count2 to smbios table type 4Julia Suvorova
In order to use the increased number of cpus, we need to bring smbios tables in line with the SMBIOS 3.0 specification. This allows us to introduce core_count2 which acts as a duplicate of core_count if we have fewer cores than 256, and contains the actual core number per socket if we have more. core_enabled2 and thread_count2 fields work the same way.

2022-11-07intel-iommu: PASID supportJason Wang
This patch introduce ECAP_PASID via "x-pasid-mode". Based on the existing support for scalable mode, we need to implement the following missing parts: 1) tag VTDAddressSpace with PASID and support IOMMU/DMA translation with PASID 2) tag IOTLB with PASID 3) PASID cache and its flush 4) PASID based IOTLB invalidation For simplicity PASID cache is not implemented so we can simply implement the PASID cache flush as a no and leave it to be implemented in the future. For PASID based IOTLB invalidation, since we haven't had L1 stage support, the PASID based IOTLB invalidation is not implemented yet. For PASID based device IOTLB invalidation, it requires the support for vhost so we forbid enabling device IOTLB when PASID is enabled now. Those work could be done in the future. Note that though PASID based IOMMU translation is ready but no device can issue PASID DMA right now. In this case, PCI_NO_PASID is used as PASID to identify the address without PASID. vtd_find_add_as() has been extended to provision address space with PASID which could be utilized by the future extension of PCI core to allow device model to use PASID based DMA translation. This feature would be useful for: 1) prototyping PASID support for devices like virtio 2) future vPASID work 3) future PRS and vSVA work Reviewed-by: Peter Xu <peterx@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com> Message-Id: <20221028061436.30093-5-jasowang@redhat.com> Reviewed-by: Michael S.

2022-11-07intel-iommu: drop VTDBusJason Wang
We introduce VTDBus structure as an intermediate step for searching the address space. This works well with SID based matching/lookup. But when we want to support SID plus PASID based address space lookup, this intermediate steps turns out to be a burden. So the patch simply drops the VTDBus structure and use the PCIBus and devfn as the key for the g_hash_table(). This simplifies the codes and the future PASID extension. To prevent being slower for past vtd_find_as_from_bus_num() callers, a vtd_as cache indexed by the bus number is introduced to store the last recent search result of a vtd_as belongs to a specific bus.

2022-11-07msix: Assert that specified vector is in rangeAkihiko Odaki
There were several different ways to deal with the situation where the vector specified for a msix function is out of bound: - early return a function and keep progresssing - propagate the error to the caller - mark msix unusable - assert it is in bound - just ignore An out-of-bound vector should not be specified if the device implementation is correct so let msix functions always assert that the specified vector is in range. An exceptional case is virtio-pci, which allows the guest to configure vectors. For virtio-pci, it is more appropriate to introduce its own checks because it is sometimes too late to check the vector range in msix functions.

PCI devices support vq reset. Based on this function, the driver can adjust the size of the ring, and quickly recycle the buffer in the ring. The migration of the virtio devices will not happen during a reset operation. This is becuase the global iothread lock is held. Migration thread also needs the lock. As a result, when migration of virtio devices starts, the 'reset' status of VirtIOPCIQueue will always be 0. Thus, we do not need to add it in vmstate_virtio_pci_modern_queue_state.

Emulation of PCIe Data Object Exchange (DOE) PCIE Base Specification r6.0 6.3 Data Object Exchange Supports multiple DOE PCIe Extended Capabilities for a single PCIe device. For each capability, a static array of DOEProtocol should be passed to pcie_doe_init(). The protocols in that array will be registered under the DOE capability structure. For each protocol, vendor ID, type, and corresponding callback function (handle_request()) should be implemented. This callback function represents how the DOE request for corresponding protocol will be handled. pcie_doe_{read/write}_config() must be appended to corresponding PCI device's config_read/write() handler to enable DOE access. In pcie_doe_read_config(), false will be returned if pci_config_read() offset is not within DOE capability range. In pcie_doe_write_config(), the function will have no affect if the address is not within the related DOE PCIE extended capability.

ppc patch queue for 2022-10-29: This queue has the second part of the ppc4xx_sdram cleanups, doorbell instructions for POWER8, new pflash handling for the e500 machine and a Radix MMU regression fix. It also has a lot of performance optimizations in the PowerPC emulation done by the researchers of the Eldorado institute. Between using gvec for VMX/VSX instructions, a full rework of the interrupt model and PMU optimizations, they managed to drastically speed up the emulation of powernv8/9/10 machines. Here's an example with avocado tests: - with master: tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8: PASS (38.89 s) tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9: PASS (43.89 s) - with this queue applied: tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8: PASS (21.23 s) tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9: PASS (22.58 s) Other ppc machines, like pseries, also had a noticeable performance boost. # -----BEGIN PGP SIGNATURE----- # # iHUEABYKAB0WIQQX6/+ZI9AYAK8oOBk82cqW3gMxZAUCY10J/gAKCRA82cqW3gMx # ZAbjAPwKNbE1wE2POJbMALBQAM5MewwLMV/UKGjE6jA7HAbb/AEA9e3o11FoUmSJ # rZkmTvMzBQZ81mMGRlS0cnqbrr4ADgc= # =gnKY # -----END PGP SIGNATURE----- # gpg: Signature made Sat 29 Oct 2022 07:09:50 EDT # gpg: using EDDSA key 17EBFF9923D01800AF2838193CD9CA96DE033164 # gpg: Good signature from "Daniel Henrique Barboza <danielhb413@gmail.com>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 17EB FF99 23D0 1800 AF28 3819 3CD9 CA96 DE03 3164 * tag 'pull-ppc-20221029' of https://gitlab.com/danielhb/qemu: (63 commits) target/ppc: Fix regression in Radix MMU hw/ppc/e500: Implement pflash handling hw/sd/sdhci: Rename ESDHC_* defines to USDHC_* hw/sd/sdhci-internal: Unexport ESDHC defines hw/block/pflash_cfi0{1, 2}: Error out if device length isn't a power of two docs/system/ppc/ppce500: Use qemu-system-ppc64 across the board(s) target/ppc: Increment PMC5 with inline insns target/ppc: Add new PMC HFLAGS ppc4xx_sdram: Add errp parameter to ppc4xx_sdram_banks() ppc4xx_sdram: Convert DDR SDRAM controller to new bank handling ppc4xx_sdram: Generalise bank setup ppc4xx_sdram: Rename local state variable for brevity ppc4xx_sdram: Use hwaddr for memory bank size ppc4xx_sdram: Move ppc4xx_sdram_banks() to ppc4xx_sdram.c ppc4xx_devs.c: Move DDR SDRAM controller model to ppc4xx_sdram.c ppc440_uc.c: Move DDR2 SDRAM controller model to ppc4xx_sdram.c target/ppc: move the p*_interrupt_powersave methods to excp_helper.c target/ppc: unify cpu->has_work based on cs->interrupt_request target/ppc: introduce ppc_maybe_interrupt target/ppc: remove ppc_store_lpcr from CONFIG_USER_ONLY builds ...
