2024-11-04virtio-pci: fix memory_region_find for VirtIOPCIRegion's MRGao Shiyuan1-0/+2
As shown below, if a virtio PCI device is attached under a pci-bridge, the MR of VirtIOPCIRegion does not belong to any address space. So memory_region_find cannot be used to search for this MR.

2024-11-04hw/acpi: Generic Port Affinity Structure supportJonathan Cameron1-0/+1
These are very similar to the recently added Generic Initiators but instead of representing an initiator of memory traffic they represent an edge point beyond which may lie either targets or initiators. Here we add these ports such that they may be targets of hmat_lb records to describe the latency and bandwidth from host side initiators to the port. A discoverable mechanism such as UEFI CDAT read from CXL devices and switches is used to discover the remainder of the path, and the OS can build up full latency and bandwidth numbers as need for work and data placement decisions.

2023-05-16hw/pci-bridge: Fix release ordering by embedding PCIBridgeWindows within ↵Jonathan Cameron1-1/+1
PCIBridge The lifetime of the PCIBridgeWindows instance accessed via the windows pointer in struct PCIBridge is managed separately from the PCIBridge itself. Triggered by ./qemu-system-x86_64 -M x-remote -display none -monitor stdio QEMU monitor: device_add cxl-downstream In some error handling paths (such as the above due to attaching a cxl-downstream port anything other than a cxl-upstream port) the g_free() of the PCIBridge windows in pci_bridge_region_cleanup() is called before the final call of flatview_uref() in address_space_set_flatview() ultimately from drain_call_rcu() At one stage this resulted in a crash, currently can still be observed using valgrind which records a use after free. When present, only one instance is allocated. pci_bridge_update_mappings() can operate directly on an instance rather than creating a new one and swapping it in. Thus there appears to be no reason to not directly couple the lifetimes of the two structures by embedding the PCIBridgeWindows within the PCIBridge removing the need for the problematic separate free. Patch is same as was posted deep in the discussion. https://lore.kernel.org/qemu-devel/20230403171232.000020bb@huawei.com/ Reported-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Message-Id: <20230421122550.28234-1-Jonathan.Cameron@huawei.com> Reviewed-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>
2023-04-24hw/pci-bridge: Make PCIe and CXL PXB Devices inherit from TYPE_PXB_DEVJonathan Cameron1-8/+20
Previously, PXB_CXL_DEVICE, PXB_PCIE_DEVICE and PXB_DEVICE all have PCI_DEVICE as their direct parent but share a common state struct PXBDev. convert_to_pxb() is used to get the PXBDev instance from which ever of these types it is called on. This patch switches to an explicit hierarchy based on shared functionality. To allow use of OBJECT_DECLARE_SIMPLE_TYPE() whilst minimizing code changes, all types are renamed to have the postfix _DEV rather than _DEVICE. The new heirarchy has PXB_CXL_DEV with parent PXB_PCIE_DEV which in turn has parent PXB_DEV which continues to have parent PCI_DEVICE. This allows simple use of PXB_DEV() etc rather than a custom function + removal of duplicated properties and moving the CXL specific elements out of struct PXBDev.

2023-03-07hw/pxb-cxl: Support passthrough HDM Decoders unless overriddenJonathan Cameron1-0/+1
The CXL r3.0 specification allows for there to be no HDM decoders on CXL Host Bridges if they have only a single root port. Instead, all accesses directed to the host bridge (as specified in CXL Fixed Memory Windows) are assumed to be routed to the single root port. Linux currently assumes this implementation choice. So to simplify testing, make QEMU emulation also default to no HDM decoders under these particular circumstances, but provide a hdm_for_passthrough boolean option to have HDM decoders as previously. Technically this is breaking backwards compatibility, but given the only known software stack used with the QEMU emulation is the Linux kernel and this configuration did not work before this change, there are unlikely to be any complaints that it now works. The option is retained to allow testing of software that does allow for these HDM decoders to exist, once someone writes it.

2022-05-13acpi/cxl: Create the CEDT (9.14.1)Ben Widawsky1-0/+20
The CXL Early Discovery Table is defined in the CXL 2.0 specification as a way for the OS to get CXL specific information from the system firmware. CXL 2.0 specification adds an _HID, ACPI0016, for CXL capable host bridges, with a _CID of PNP0A08 (PCIe host bridge). CXL aware software is able to use this initiate the proper _OSC method, and get the _UID which is referenced by the CEDT. Therefore the existence of an ACPI0016 device allows a CXL aware driver perform the necessary actions. For a CXL capable OS, this works. For a CXL unaware OS, this works. CEDT awaremess requires more. The motivation for ACPI0017 is to provide the possibility of having a Linux CXL module that can work on a legacy Linux kernel. Linux core PCI/ACPI which won't be built as a module, will see the _CID of PNP0A08 and bind a driver to it. If we later loaded a driver for ACPI0016, Linux won't be able to bind it to the hardware because it has already bound the PNP0A08 driver. The ACPI0017 device is an opportunity to have an object to bind a driver will be used by a Linux driver to walk the CXL topology and do everything that we would have preferred to do with ACPI0016. There is another motivation for an ACPI0017 device which isn't implemented here. An operating system needs an attach point for a non-volatile region provider that understands cross-hostbridge interleaving. Since QEMU emulation doesn't support interleaving yet, this is more important on the OS side, for now. As of CXL 2.0 spec, only 1 sub structure is defined, the CXL Host Bridge Structure (CHBS) which is primarily useful for telling the OS exactly where the MMIO for the host bridge is.

This handler will then pass control to the bus hotplug handler.
