The intent of this file is to serve as a misc. utilities file to be shared amongst tests that are utilizing libqos facilities. In a later patch, migration test helpers will be added to libqos.c that will allow simplified testing of migration cases where libqos is "Just Enough OS" for migrations testing. The addition of the AHCIQState structure will also allow us to eliminate global variables inside of qtests to manage allocators and test instances in a better, more functional way. libqos.c: - Add qtest_boot - Add qtest_shutdown libqos.h: - Create QOSState structure for allocator and QTestState. ahci-test.c: - Move qtest_boot and qtest_shutdown to libqos.c/h - Create AHCIQState to interface with new qtest_boot/shutdown prototypes - Modify tests slightly to use new types. For now, the new object file is only linked to ahci-test, because it still relies on pc architecture specific code in libqos. The next two patches will reorganize the code to be more general.

Before this patch, the "opaque" pointer in an NBD BDS points to a BDRVNBDState, which contains an NbdClientSession object, which in turn contains a pointer to the BDS. This pointer may become invalid due to bdrv_swap(), so drop it, and instead pass the BDS directly to the nbd-client.c functions which then retrieve the NbdClientSession object from there.

由 Peter Maydell 提交于
The code in logic_imm_decode_wmask attempts to rotate a mask value within the bottom 'e' bits of the value with mask = (mask >> r) | (mask << (e - r)); This has two issues: * if the element size is 64 then a rotate by zero results in a shift left by 64, which is undefined behaviour * if the element size is smaller than 64 then this will leave junk in the value at bit 'e' and above, which is not valid input to bitfield_replicate(). As it happens, the bits at bit 'e' to '2e - r' are exactly the ones which bitfield_replicate is going to copy in there, so this isn't a "wrong code generated" bug, but it's confusing and if we ever put an assert in bitfield_replicate it would fire on valid guest code. Fix the former by not doing anything if r is zero, and the latter by masking with bitmask64(e).

With simple exposure of MMFG, ioport window, mmio window and an IRQ line we can successfully create a workable PCIe host bridge that can be mapped anywhere and only needs to get described to the OS using whatever means it likes. This patch implements such a "generic" host bridge. It handles 4 legacy IRQ lines. MSIs need to be handled external to the host bridge. This device is particularly useful for the "pci-host-ecam-generic" driver in Linux.

The difference between v1 and v2 is fairly subtle, simply more deterministic behavior for unmaps. The v1 interface allows the user to attempt to unmap sub-regions of previous mappings, returning success with zero size if unable to comply. This was a reflection of the underlying IOMMU API. The v2 interface requires that the user may only unmap fully contained mappings, ie. an unmap cannot intersect or bisect a previous mapping, but may cover multiple mappings. QEMU never made use of the sub-region v1 support anyway, so we can support either v1 or v2. We'll favor v2 since it's newer. Signed-off-by: NAlex Williamson <alex.williamson@redhat.com>

In the case of VFIO, the unrealize callback is too early to munmap the BARs. The munmap must be delayed until memory accesses are complete. To do this, split vfio_unmap_bars in two. The removal step, now called vfio_unregister_bars, remains in vfio_exitfn. The reclamation step is vfio_unmap_bars and is moved to the instance_finalize callback. Similarly, quirk MemoryRegions have to be removed during vfio_unregister_bars, but freeing the data structure must be delayed to vfio_unmap_bars.

In order to enable out-of-BQL address space lookup, destruction of devices needs to be split in two phases. Unrealize is the first phase; once it complete no new accesses will be started, but there may still be pending memory accesses can still be completed. The second part is freeing the device, which only happens once all memory accesses are complete. At this point the reference count has dropped to zero, an RCU grace period must have completed (because the RCU-protected FlatViews hold a reference to the device via memory_region_ref). This is when instance_finalize is called. Freeing data belongs in an instance_finalize callback, because the dynamically allocated memory can still be used after unrealize by the pending memory accesses. This starts the process by creating an instance_finalize callback and freeing most of the dynamically-allocated data in instance_finalize. Because instance_finalize is also called on error paths or also when the device is actually not realized, the common code needs some changes to be ready for this. The error path in vfio_initfn can be simplified too. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NAlex Williamson <alex.williamson@redhat.com>

Now that vfio_put_base_device is called unconditionally at instance_finalize time, it can be called twice if vfio_populate_device fails. This works but it is slightly harder to follow. Change vfio_get_device to not touch the vbasedev struct until it will definitely succeed, moving the vfio_populate_device call back to vfio-pci. This way, vfio_put_base_device will only be called once. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NAlex Williamson <alex.williamson@redhat.com>

address_space_destroy_dispatch is called from an RCU callback and hence outside the iothread mutex (BQL). However, after address_space_destroy no new accesses can hit the destroyed AddressSpace so it is not necessary to observe changes to the memory map.
