Let's use a wrapper instead of looking it up manually. This function can than be reused when we explicitly want to have the bus hotplug handler (e.g. when the bus hotplug handler was overwritten by the machine hotplug handler).

it will allow to return another hotplug handler than the default one for a specific bus based device type. Which is needed to handle non trivial plug/unplug sequences that need the access to resources configured outside of bus where device is attached. That will allow for returned hotplug handler to orchestrate wiring in arbitrary order, by chaining other hotplug handlers when it's needed. PS: It could be used for hybrid virtio-mem and virtio-pmem devices where it will return machine as hotplug handler which will do necessary wiring at machine level and then pass control down the chain to bus specific hotplug handler. Example of top level hotplug handler override and custom plug sequence: some_machine_get_hotplug_handler(machine){ if (object_dynamic_cast(OBJECT(dev), TYPE_SOME_BUS_DEVICE)) { return HOTPLUG_HANDLER(machine); } return NULL; } some_machine_device_plug(hotplug_dev, dev) { if (object_dynamic_cast(OBJECT(dev), TYPE_SOME_BUS_DEVICE)) { /* do machine specific initialization */ some_machine_init_special_device(dev) /* pass control to bus specific handler */ hotplug_handler_plug(dev->parent_bus->hotplug_handler, dev) } } Reviewed-by: NDavid Gibson <david@gibson.dropbear.id.au> Signed-off-by: NIgor Mammedov <imammedo@redhat.com> Signed-off-by: NDavid Hildenbrand <david@redhat.com> Message-Id: <20190228122849.4296-3-david@redhat.com> Signed-off-by: NEduardo Habkost <ehabkost@redhat.com>

The qbus_is_full(BusState *bus) function (qdev_monitor.c) compares the max_index value of the BusState structure with the max_dev value of the BusClass structure to determine whether the maximum number of children has been reached for the bus. The problem is, the max_index field of the BusState structure does not necessarily reflect the number of devices that have been plugged into the bus. Whenever a child device is plugged into the bus, the bus's max_index value is assigned to the child device and then incremented. If the child is subsequently unplugged, the value of the max_index does not change and no longer reflects the number of children. When the bus's max_index value reaches the maximum number of devices allowed for the bus (i.e., the max_dev field in the BusClass structure), attempts to plug another device will be rejected claiming that the bus is full -- even if the bus is actually empty. To resolve the problem, a new 'num_children' field is being added to the BusState structure to keep track of the number of children plugged into the bus. It will be incremented when a child is plugged, and decremented when a child is unplugged.

Up to now the memory map has been static and the high IO region base has always been 256GiB. This patch modifies the virt_set_memmap() function, which freezes the memory map, so that the high IO range base becomes floating, located after the initial RAM and the device memory. The function computes - the base of the device memory, - the size of the device memory, - the high IO region base - the highest GPA used in the memory map. Entries of the high IO region are assigned a base address. The device memory is initialized. The highest GPA used in the memory map will be used at VM creation to choose the requested IPA size. Setting all the existing highmem IO regions beyond the RAM allows to have a single contiguous RAM region (initial RAM and possible hotpluggable device memory). That way we do not need to do invasive changes in the EDK2 FW to support a dynamic RAM base. Still the user cannot request an initial RAM size greater than 255GB.

In the prospect to introduce an extended memory map supporting more RAM, let's split the memory map array into two parts: - the former a15memmap, renamed base_memmap, contains regions below and including the RAM. MemMapEntries initialized in this array have a static size and base address. - extended_memmap, only initialized with entries located after the RAM. MemMapEntries initialized in this array only get their size initialized. Their base address is dynamically computed depending on the the top of the RAM, with same alignment as their size. Eventually base_memmap entries are copied into the extended_memmap array. Using two separate arrays however clarifies which entries are statically allocated and those which are dynamically allocated. This new split will allow to grow the RAM size without changing the description of the high IO entries. We introduce a new virt_set_memmap() helper function which "freezes" the memory map. We call it in machvirt_init as memory attributes of the machine are not yet set when virt_instance_init() gets called. The memory map is unchanged (the top of the initial RAM still is 256GiB). Then come the high IO regions with same layout as before.

At the moment the handling of init-svtor and cpuwait initial values is split between armsse.c and iotkit-sysctl.c: the code in armsse.c sets the initial state of the CPU object by setting the init-svtor and start-powered-off properties, but the iotkit-sysctl.c code has its own code setting the reset values of its registers (which are then used when updating the CPU when the guest makes runtime changes). Clean this up by making the armsse.c code set properties on the iotkit-sysctl object to define the initial values of the registers, so they always match the initial CPU state, and update the comments in armsse.c accordingly.

The I2C block read function of pm_smbus was completely broken. It required doing some direct I2C handling because it didn't have a defined size, the OS code just reads bytes until it marks the transaction finished. This also required adjusting how the AMIBIOS workaround code worked, the I2C block mode was setting STS_HOST_BUSY during a transaction, so that bit could no longer be used to inform the host status read code to start the transaction. Create a explicit bool for that operation. Also, don't read the next byte from the device in byte-by-byte mode unless the OS is actually clearing the byte done bit. Just assuming that's what the OS is doing is a bad idea. Signed-off-by: NCorey Minyard <cminyard@mvista.com>

To support PHB hotplug we need to clean up lingering references, memory, child properties, etc. prior to the PHB object being finalized. Generally this will be called as a result of calling object_unparent() on the PHB object, which in turn would normally be called as the result of an unplug() operation. When the PHB is finalized, child objects will be unparented in turn, and finalized if the PHB was the only reference holder. so we don't bother to explicitly unparent child objects of the PHB, with the notable exception of DRCs. This is needed to avoid a QEMU crash when unplugging a PHB and resetting the machine before the guest could handle the event. The DRCs are removed from the QOM tree by pci_unregister_root_bus() and we must make sure we're not leaving stale aliases under the global /dr-connector path. The formula that gives the number of DMA windows is moved to an inline function in the hw/pci-host/spapr.h header because it will have other users. The unrealize function is able to cope with partially realized PHBs. It is hence used to implement proper rollback on the realize error path.

The pseries machine only uses LSIs to support legacy PCI devices. Every PHB claims 4 LSIs at realize time. When using in-kernel XICS (or upcoming in-kernel XIVE), QEMU synchronizes the state of all irqs, including these LSIs, later on at machine reset. In order to support PHB hotplug, we need a way to tell KVM about the LSIs that doesn't require a machine reset. An easy way to do that is to always inform KVM when an interrupt is claimed, which really isn't a performance path.

The current logic is to provide the FDT fragment when attaching a device to a DRC. This works perfectly fine for our current hotplug support, but soon we will add support for PHB hotplug which has some constraints, that CPU, PCI and LMB devices don't seem to have. The first constraint is that the "ibm,dma-window" property of the PHB node requires the IOMMU to be configured, ie, spapr_tce_table_enable() has been called, which happens during PHB reset. It is okay in the case of hotplug since the device is reset before the hotplug handler is called. On the contrary with coldplug, the hotplug handler is called first and device is only reset during the initial system reset. Trying to create the FDT fragment on the hotplug path in this case, would result in somthing like this: ibm,dma-window = < 0x80000000 0x00 0x00 0x00 0x00 >; This will cause linux in the guest to panic, by simply removing and re-adding the PHB using the drmgr command: page = alloc_pages_node(nid, GFP_KERNEL, get_order(sz)); if (!page) panic("iommu_init_table: Can't allocate %ld bytes\n", sz); The second and maybe more problematic constraint is that the "interrupt-map" property needs to reference the interrupt controller node using the very same phandle that SLOF has already exposed to the guest. QEMU requires SLOF to call the private KVMPPC_H_UPDATE_DT hcall at some point to know about this phandle. With the latest QEMU and SLOF, this happens when SLOF gets quiesced. This means that if the PHB gets hotplugged after CAS but before SLOF quiesce, then we're sure that the phandle is not known when the hotplug handler is called. The FDT is only needed when the guest first invokes RTAS to configure the connector actually, long after SLOF quiesce. Let's postpone the creation of FDT fragments for PHBs to rtas_ibm_configure_connector(). Since we only need this for PHBs, introduce a new method in the base DRC class for that. DRC subtypes will be converted to use it in subsequent patches. Allow spapr_drc_attach() to be passed a NULL fdt argument if the method is available. When all DRC subtypes have been converted, the fdt argument will eventually disappear.

The HW relies on LPCR:HR along with the PATE to determine whether to use Radix or Hash mode. In fact it uses LPCR:HR more commonly than the PATE. For us, it's also more efficient to do so, especially since unlike the HW we do not maintain a cache of the current PATE and HV PATE in a generic place. Prepare the grounds for that by ensuring that LPCR:HR is set properly on SPAPR machines. Another option would have been to use a callback to get the PATE but this gets messy when implementing bare metal support, it's much simpler (and faster) to use LPCR. Since existing migration streams may not have it, fix it up in spapr_post_load() as well based on the pseudo-PATE entry that we keep.
