2023-01-08include/hw/pci: Split pci_device.h off pci.hMarkus Armbruster1-1/+1
PCIDeviceClass and PCIDevice are defined in pci.h. Many users of the header don't actually need them. Similar structs live in their own headers: PCIBusClass and PCIBus in pci_bus.h, PCIBridge in pci_bridge.h, PCIHostBridgeClass and PCIHostState in pci_host.h, PCIExpressHost in pcie_host.h, and PCIERootPortClass, PCIEPort, and PCIESlot in pcie_port.h. Move PCIDeviceClass and PCIDeviceClass to new pci_device.h, along with the code that needs them. Adjust include directives. This also enables the next commit.

2021-04-19mptsas: Remove unused MPTSASState 'pending' field (CVE-2021-3392)Michael Tokarev1-1/+0
While processing SCSI i/o requests in mptsas_process_scsi_io_request(), the Megaraid emulator appends new MPTSASRequest object 'req' to the 's->pending' queue. In case of an error, this same object gets dequeued in mptsas_free_request() only if SCSIRequest object 'req->sreq' is initialised. This may lead to a use-after-free issue. Since s->pending is actually not used, simply remove it from MPTSASState.

2020-09-09Move QOM typedefs and add missing includesEduardo Habkost1-0/+1
Some typedefs and macros are defined after the type check macros. This makes it difficult to automatically replace their definitions with OBJECT_DECLARE_TYPE. Patch generated using: $ ./scripts/codeconverter/converter.py -i \ --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]') which will split "typdef struct { ... } TypedefName" declarations. Followed by: $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \ $(git grep -l '' -- '*.[ch]') which will: - move the typedefs and #defines above the type check macros - add missing #include "qom/object.h" lines if necessary Reviewed-by: Daniel P.

2016-02-09hw: Add support for LSI SAS1068 (mptsas) devicePaolo Bonzini1-0/+100
This adds the SAS1068 device, a SAS disk controller used in VMware that is oldish but widely supported and has decent performance. Unlike megasas, it presents itself as a SAS controller and not as a RAID controller. The device corresponds to the mptsas kernel driver in Linux. A few small things in the device setup are based on Don Slutz's old patch, but the device emulation was written from scratch based on Don's SeaBIOS patch and on the FreeBSD and Linux drivers. It is 2400 lines shorter than Don's patch (and roughly the same size as MegaSAS---also because it doesn't support the similar SPI controller), implements SCSI task management functions (with asynchronous cancellation), supports big-endian hosts, has complete support for migration and follows the QEMU coding standards much more closely. To write the driver, I first split Don's patch in two parts, with the configuration bits in one file and the rest in a separate file. I first left mptconfig.c in place and rewrote the rest, then deleted mptconfig.c as well. The configuration pages are still based mostly on VirtualBox's, though not exactly the same. However, the implementation is completely different. The contents of the pages themselves should not be copyrightable.
