2019-10-04memory: allow memory_region_register_iommu_notifier() to failEric Auger
Currently, when a notifier is attempted to be registered and its flags are not supported (especially the MAP one) by the IOMMU MR, we generally abruptly exit in the IOMMU code. The failure could be handled more nicely in the caller and especially in the VFIO code. So let's allow memory_region_register_iommu_notifier() to fail as well as notify_flag_changed() callback. All sites implementing the callback are updated. This patch does not yet remove the exit(1) in the amd_iommu code. in SMMUv3 we turn the warning message into an error message saying that the assigned device would not work properly.

2019-10-04vfio: Turn the container error into an Error handleEric Auger
The container error integer field is currently used to store the first error potentially encountered during any vfio_listener_region_add() call. However this fails to propagate detailed error messages up to the vfio_connect_container caller. Instead of using an integer, let's use an Error handle. Messages are slightly reworded to accomodate the propagation. Signed-off-by: Eric Auger <eric.auger@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-09-30kvm: split too big memory section on several memslotsIgor Mammedov
Max memslot size supported by kvm on s390 is 8Tb, move logic of splitting RAM in chunks upto 8T to KVM code. This way it will hide KVM specific restrictions in KVM code and won't affect board level design decisions. Which would allow us to avoid misusing memory_region_allocate_system_memory() API and eventually use a single hostmem backend for guest RAM.

2019-09-25cputlb: Merge and move memory_notdirty_write_{prepare,complete}Richard Henderson
Since 9458a9a1df1a, all readers of the dirty bitmaps wait for the rcu lock, which means that they wait until the end of any executing TranslationBlock. As a consequence, there is no need for the actual access to happen in between the _prepare and _complete. Therefore, we can improve things by merging the two functions into notdirty_write and dropping the NotDirtyInfo structure. In addition, the only users of notdirty_write are in cputlb.c, so move the merged function there. Pass in the CPUIOTLBEntry from which the ram_addr_t may be computed.

2019-09-24nbd: Grab aio context lock in more placesEric Blake
When iothreads are in use, the failure to grab the aio context results in an assertion failure when trying to unlock things during blk_unref, when trying to unlock a mutex that was not locked. In short, all calls to nbd_export_put need to done while within the correct aio context. But since nbd_export_put can recursively reach itself via nbd_export_close, and recursively grabbing the context would deadlock, we can't do the context grab directly in those functions, but must do so in their callers. Hoist the use of the correct aio_context from nbd_export_new() to its caller qmp_nbd_server_add(). Then tweak qmp_nbd_server_remove(), nbd_eject_notifier(), and nbd_esport_close_all() to grab the right context, so that all callers during qemu now own the context before nbd_export_put() can call blk_unref(). Remaining uses in qemu-nbd don't matter (since that use case does not support iothreads).

2019-09-24xen: perform XenDevice clean-up in XenBus watch handlerPaul Durrant
Cleaning up offline XenDevice objects directly in xen_device_backend_changed() is dangerous as xen_device_unrealize() will modify the watch list that is being walked. Even the QLIST_FOREACH_SAFE() used in notifier_list_notify() is insufficient as *two* notifiers (for the frontend and backend watches) are removed, thus potentially rendering the 'next' pointer unsafe. The solution is to use the XenBus backend_watch handler to do the clean-up instead, as it is invoked whilst walking a separate watch list. This patch therefore adds a new 'inactive_devices' list to XenBus, to which offline devices are added by xen_device_backend_changed(). The XenBus backend_watch registration is also changed to not only invoke xen_bus_enumerate() but also a new xen_bus_cleanup() function, which will walk 'inactive_devices' and perform the necessary actions. For safety an extra 'online' check is also added to xen_bus_type_enumerate() to make sure that no attempt is made to create a new XenDevice object for a backend that is offline. NOTE: This patch also includes some cosmetic changes: - substitute the local variable name 'backend_state' in xen_bus_type_enumerate() with 'state', since there is no ambiguity with any other state in that context. - change xen_device_state_is_active() to xen_device_frontend_is_active() (and pass a XenDevice directly) since the state tests contained therein only apply to a frontend. - use 'state' rather then 'xendev->backend_state' in xen_device_backend_changed() to shorten the code.

Xenstore watch call-backs are already abstracted away from XenBus using the XenWatch data structure but the associated NotifierList manipulation and file handle registration is still open coded in various xen_bus_...() functions. This patch creates a new XenWatchList data structure to allow these interactions to be abstracted away from XenBus as well. This is in preparation for a subsequent patch which will introduce separate watch lists for XenBus and XenDevice objects. NOTE: This patch also introduces a new notifier_list_empty() helper function for the purposes of adding an assertion that a XenWatchList is not freed whilst its associated NotifierList is still occupied.

'remotes/palmer/tags/riscv-for-master-4.2-sf1-v3' into staging RISC-V Patches for the 4.2 Soft Freeze, Part 1, v3 This contains quite a few patches that I'd like to target for 4.2. They're mostly emulation fixes for the sifive_u board, which now much more closely matches the hardware and can therefor run the same fireware as what gets loaded onto the board. Additional user-visible improvements include: * support for loading initrd files from the command line into Linux, via /chosen/linux,initrd-{start,end} device tree nodes. * The conversion of LOG_TRACE to trace events. * The addition of clock DT nodes for our uart and ethernet. This also includes some preliminary work for the H extension patches, but does not include the H extension patches as I haven't had time to review them yet. This passes my OE boot test on 32-bit and 64-bit virt machines, as well as a 64-bit upstream Linux boot on the sifive_u machine. It has been fixed to actually pass "make check" this time. Changes since v2 (never made it to the list): * Sets the sifive_u machine default core count to 2 instead of 5. Changes since v1 <20190910190513.21160-1-palmer@sifive.com>: * Sets the sifive_u machine default core count to 5 instead of 1, as it's impossible to have a single core sifive_u machine. # gpg: Signature made Tue 17 Sep 2019 16:43:30 BST # gpg: using RSA key 00CE76D1834960DFCE886DF8EF4CA1502CCBAB41 # gpg: issuer "palmer@dabbelt.com" # gpg: Good signature from "Palmer Dabbelt <palmer@dabbelt.com>" [unknown] # gpg: aka "Palmer Dabbelt <palmer@sifive.com>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 00CE 76D1 8349 60DF CE88 6DF8 EF4C A150 2CCB AB41 * remotes/palmer/tags/riscv-for-master-4.2-sf1-v3: (48 commits) gdbstub: riscv: fix the fflags registers target/riscv: Use TB_FLAGS_MSTATUS_FS for floating point target/riscv: Fix mstatus dirty mask target/riscv: Use both register name and ABI name riscv: sifive_u: Update model and compatible strings in device tree riscv: sifive_u: Remove handcrafted clock nodes for UART and ethernet riscv: sifive_u: Fix broken GEM support riscv: sifive_u: Instantiate OTP memory with a serial number riscv: sifive: Implement a model for SiFive FU540 OTP riscv: roms: Update default bios for sifive_u machine riscv: sifive_u: Change UART node name in device tree riscv: sifive_u: Update UART base addresses and IRQs riscv: sifive_u: Reference PRCI clocks in UART and ethernet nodes riscv: sifive_u: Add PRCI block to the SoC riscv: sifive_u: Generate hfclk and rtcclk nodes riscv: sifive: Implement PRCI model for FU540 riscv: sifive_u: Update PLIC hart topology configuration string riscv: sifive_u: Update hart configuration to reflect the real FU540 SoC riscv: sifive_u: Set the minimum number of cpus to 2 riscv: hart: Add a "hartid-base" property to RISC-V hart array ...

"qemu/cutils.h" contains various qemu_strtosz_*() functions useful to convert strings to size. It seems natural to have the opposite usage (from size to string) there too. The function definition is already in util/cutils.c.

2019-09-17riscv: sifive_u: Remove handcrafted clock nodes for UART and ethernetBin Meng
In the past we did not have a model for PRCI, hence two handcrafted clock nodes ("/soc/ethclk" and "/soc/uartclk") were created for the purpose of supplying hard-coded clock frequencies. But now since we have added the PRCI support in QEMU, we don't need them any more.

2019-09-17riscv: sifive_u: Fix broken GEM supportBin Meng
At present the GEM support in sifive_u machine is seriously broken. The GEM block register base was set to a weird number (0x100900FC), which for no way could work with the cadence_gem model in QEMU. Not like other GEM variants, the FU540-specific GEM has a management block to control 10/100/1000Mbps link speed changes, that is mapped to 0x100a0000. We can simply map it into MMIO space without special handling using create_unimplemented_device(). Update the GEM node compatible string to use the official name used by the upstream Linux kernel, and add the management block reg base & size to the <reg> property encoding. Tested with upstream U-Boot and Linux kernel MACB drivers.
