2015-02-13target-arm: A64: Fix handling of rotate in logic_imm_decode_wmaskPeter Maydell1-1/+4
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).

2015-02-13pci: Add generic PCIe host bridgeAlexander Graf3-0/+211
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.

2015-02-10vfio: Use vfio type1 v2 IOMMU interfaceAlex Williamson1-2/+6
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: Alex Williamson <alex.williamson@redhat.com>
2015-02-10vfio: unmap and free BAR data in instance_finalizePaolo Bonzini1-8/+57
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.

2015-02-10vfio: free dynamically-allocated data in instance_finalizePaolo Bonzini2-11/+18
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: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2015-02-10vfio: cleanup vfio_get_device error path, remove vfio_populate_device callbackPaolo Bonzini3-23/+19
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: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2015-02-10memory: unregister AddressSpace MemoryListener within BQLPaolo Bonzini3-1/+7
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. Move the memory_listener_unregister call earlier, to make it thread-safe again.

2015-02-10util/uri: URI member path can be null, compare more carfullyMarkus Armbruster1-1/+2
uri_resolve_relative() calls strcmp(bas->path, ref->path). However, either argument could be null! Evidence: the code checks for null after the comparison. Spotted by Coverity. I suspect this was screwed up when we stole the code from libxml2. There the conditional reads xmlStrEqual((xmlChar *)bas->path, (xmlChar *)ref->path) with int xmlStrEqual(const xmlChar *str1, const xmlChar *str2) { if (str1 == str2) return(1); if (str1 == NULL) return(0); if (str2 == NULL) return(0); do { if (*str1++ != *str2) return(0); } while (*str2++); return(1); } Fix by replicating libxml2's logic faithfully.
