2019-02-04s390x/pci: Introduce unplug requests and split unplug handlerDavid Hildenbrand2-54/+113
PCI on s390x is really weird and how it was modeled in QEMU might not have been the right choice. Anyhow, right now it is the case that: - Hotplugging a PCI device will silently create a zPCI device (if none is provided) - Hotunplugging a zPCI device will unplug the PCI device (if any) - Hotunplugging a PCI device will unplug also the zPCI device As far as I can see, we can no longer change this behavior. But we should fix it. Both device types are handled via a single hotplug handler call. This is problematic for various reasons: 1. Unplugging via the zPCI device allows to unplug devices that are not hot removable. (check performed in qdev_unplug()) - bad. 2. Hotplug handler chains are not possible for the unplug case. In the future, the machine might want to override hotplug handlers, to process device specific stuff and to then branch off to the actual hotplug handler. We need separate hotplug handler calls for both the PCI and zPCI device to make this work reliably. All other PCI implementations are already prepared to handle this correctly, only s390x is missing. Therefore, introduce the unplug_request handler and properly perform unplug checks by redirecting to the separate unplug_request handlers. When finally unplugging, perform two separate hotplug_handler_unplug() calls, first for the PCI device, followed by the zPCI device. This now nicely splits unplugging paths for both devices. The redirect part is a little hairy, as the user is allowed to trigger unplug either via the PCI or the zPCI device. So redirect always to the PCI unplug request handler first and remember if that check has been performed in the zPCI device. Redirect then to the zPCI device unplug request handler to perform the magic. Remembering that we already checked the PCI device breaks the redirect loop.

2019-02-04xen: fix xen-bus state model to allow frontend re-connectionPaul Durrant1-13/+19
There is a flaw in the xen-bus state model. To allow a frontend to re- connect the backend state of an online XenDevice is transitioned from Closed to InitWait, but this is currently done unilaterally which is incorrect. The backend state should remain Closed until the frontend state transitions to Initialising. This patch removes the automatic backend state transition from xen_device_backend_state_changed() and, instead, adds an extra check in xen_device_frontend_state_changed() to determine whether a frontend is trying to re-connect to a previously Closed XenDevice. Only if this is found to be the case is the backend state transitioned from Closed to InitWait. Note that this transition will be common amongst all XenDevice classes and hence xen_device_frontend_state_changed() returns immediately afterwards without calling into the XenDeviceClass frontend_changed() method.

2019-02-04mmap-alloc: fix hugetlbfs misaligned length in ppc64Murilo Opsfelder Araujo4-10/+20
The commit 7197fb4058bcb68986bae2bb2c04d6370f3e7218 ("util/mmap-alloc: fix hugetlb support on ppc64") fixed Huge TLB mappings on ppc64. However, we still need to consider the underlying huge page size during munmap() because it requires that both address and length be a multiple of the underlying huge page size for Huge TLB mappings. Quote from "Huge page (Huge TLB) mappings" paragraph under NOTES section of the munmap(2) manual: "For munmap(), addr and length must both be a multiple of the underlying huge page size." On ppc64, the munmap() in qemu_ram_munmap() does not work for Huge TLB mappings because the mapped segment can be aligned with the underlying huge page size, not aligned with the native system page size, as returned by getpagesize(). This has the side effect of not releasing huge pages back to the pool after a hugetlbfs file-backed memory device is hot-unplugged. This patch fixes the situation in qemu_ram_mmap() and qemu_ram_munmap() by considering the underlying page size on ppc64. After this patch, memory hot-unplug releases huge pages back to the pool.

To make things slightly more messy, we also add a relocatable bit (b_n()) although in the right endianness. This fixes endianness of assigned->phys_hi. This is unlikely to produce any visible difference though as we should end up there only in the case of PCI hotplug and even then I am not sure if (d->io_regions[i].addr == PCI_BAR_UNMAPPED) == true.

2019-02-04hw/ppc: Move ppc40x_*reset() functions from ppc405_uc.c to ppc.cThomas Huth3-60/+57
Currently, it is not possible to build a QEMU binary without the ppc405_uc.c file, even if you do not want to have the embedded machines in the binary. This is bad since it's quite a bit of code and this code pulls in some more dependencies (e.g. via the usage of serial_mm_init()) which would not be needed otherwise - especially with the upcoming Kconfig-style configuration system for QEMU. The only functions from this file which are really always required for linking are the ppc40x_*reset() functions, so move these functions to ppc.c, close to the ppc40x_set_irq() function that calls them. Now we can flag ppc405_uc.c and ppc4xx_devs.c with the CONFIG_PPC4XX config switch, too. And while we're at it, replace the printf()s in these ppc40x_*reset() functions with proper calls to qemu_log_mask().

2019-02-04spapr/pci: Fix primary bus number for PCI bridgesDavid Hildenbrand1-4/+1
While looking at the s390x implementation, looks like spapr has a similar BUG when building the topology. The primary bus number corresponds always to the bus number of the bus the bridge is attached to. Right now, if we have two bridges attached to the same bus (e.g. root bus) this is however not the case. The first bridge will have primary bus 0, the second bridge primary bus 1, which is wrong. Fix the assignment. While at it, drop setting the PCI_SUBORDINATE_BUS temporarily to 0xff. Setting it temporarily to that value (as discussed e.g. in [1]), is only relevant for a running system that probes the buses. The value is effectively unused for us just doing a DFS.

They are not used outside their files so don't clash but they are also not identical so rename the ppc440 specific one to distinguish them.

2019-02-04ppc4xx: Use ram_addr_t in ppc4xx_sdram_adjust()BALATON Zoltan4-5/+5
To avoid overflow if larger values are added later use ram_addr_t for the sdram_bank_sizes parameter to match ram_size to which it is compared. Signed-off-by: BALATON Zoltan <balaton@eik.bme.hu> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2019-02-04sam460ex: Clean up SPD EEPROM creationBALATON Zoltan1-153/+20
Get rid of code from MIPS Malta board used to create SPD EEPROM data (parts of which was not even needed for sam460ex) and use the generic spd_data_generate() function to simplify this. Signed-off-by: BALATON Zoltan <balaton@eik.bme.hu> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2019-02-04smbus: Add a helper to generate SPD EEPROM dataBALATON Zoltan2-0/+132
There are several boards with SPD EEPROMs that are now using duplicated or slightly different hard coded data. Add a helper to generate SPD data for a memory module of given type and size that could be used by these boards (either as is or with further changes if needed) which should help cleaning this up and avoid further duplication.

2019-02-04scripts/update-linux-headers.sh: adjust for Linux 4.21-rc1 (or 5.0-rc1)Paolo Bonzini1-0/+11
There are three new indirect inclusions: vhost_types.h, which we'll shortly put to use as a portable header and thus is copied to standard-headers; and new per-subtarget versions of MIPS unistd.h and PowerPC unistd.h. Because vhost.h includes vhost_types.h, we also need a proxy include from linux/vhost.h to standard-headers. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Michael S.

2019-02-04contrib/libvhost-user: switch to uint64_tMichael S. Tsirkin1-4/+4
contrib/libvhost-user is now using __u64 which is a long long. New linux headers will use uint64_t. These need to be printed differently: llx versus PRIx64. For now cast to uint64_t for portability so the change does not break the build. Casts will go away in the future. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2019-02-01virtio: add checks for the size of the indirect tableDima Stepanov1-2/+2
The virtqueue_pop() and virtqueue_get_avail_bytes() routines can use the INDIRECT table to get the data. It is possible to create a packet which will lead to the assert message like: include/exec/memory.h:1995: void address_space_read_cached(MemoryRegionCache *, hwaddr, void *, int): Assertion `addr < cache->len && len <= cache->len - addr' failed. Aborted To do it the first descriptor should have a link to the INDIRECT table and set the size of it to 0. It doesn't look good that the guest should be able to trigger the assert in qemu. Add additional check for the size of the INDIRECT table, which should not be 0. Signed-off-by: Dima Stepanov <dimastep@yandex-team.ru> Reviewed-by: Michael S.
