ppc patch queue 2017-07-17 This pull requests supersedes the one from 2017-07-14. That one had a couple of subtle regressions: there was a build error for mingw32, and an instance_size which was theoretically wrong everywhere, but only actually bit on the Travis OSX build. There are two major batches in this set, rather than the usual collection of assorted fixes. * More DRC cleanup. This gets the state management into a state which should fix many of the hotplug+migration problems we've had. Plus it gets the migration stream format into something well defined and pretty minimal which we can reasonably support into the future. * Hashed Page Table resizing. It's been a while since this was posted, but it's been through several previous rounds of review. The kernel parts (both guest and host) are merged in 4.11, so this is the only remaining piece left to allow resizing of the HPT in a running guest. There are also a handful of unrelated fixes. # gpg: Signature made Mon 17 Jul 2017 07:36:52 BST # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.10-20170717: (21 commits) target/ppc: fix CPU hotplug when radix is enabled (TCG) spapr: fix memory leak in spapr_core_pre_plug() pseries: Allow HPT resizing with KVM pseries: Use smaller default hash page tables when guest can resize pseries: Enable HPT resizing for 2.10 pseries: Implement HPT resizing pseries: Stubs for HPT resizing ppc/pnv: Remove unused XICSState reference spapr: fix potential memory leak in spapr_core_plug() spapr: Implement DR-indicator for physical DRCs only spapr: Remove sPAPRConfigureConnectorState sub-structure spapr: Consolidate DRC state variables spapr: Cleanups relating to DRC awaiting_release field spapr: Refactor spapr_drc_detach() spapr: Abort on delete failure in spapr_drc_release() spapr: Simplify unplug path spapr: Remove 'awaiting_allocation' DRC flag spapr: Treat devices added before inbound migration as coldplugged spapr: Minor cleanups to events handling spapr: migrate pending_events of spapr state ...

The current VNC default keyboard delay is 1ms. With that we're constantly typing faster than the guest receives keyboard events from an XHCI attached USB HID device. The default keyboard delay time in the input layer however is 10ms. I don't know how that number came to be, but empirical tests on some OpenQA driven ARM systems show that 10ms really is a reasonable default number for the delay. This patch moves the VNC delay also to 10ms. That way our default is much safer (good!) and also consistent with the input layer default (also good!).

So far, qemu implements the PAPR Hash Page Table (HPT) resizing extension with TCG. The same implementation will work with KVM PR, but we don't currently allow that. For KVM HV we can only implement resizing with the assistance of the host kernel, which needs a new capability and ioctl()s. This patch adds support for testing the new KVM capability and implementing the resize in terms of KVM facilities when necessary. If we're running on a kernel which doesn't have the new capability flag at all, we fall back to testing for PR vs. HV KVM using the same hack that we already use in a number of places for older kernels.

We've now implemented a PAPR extension allowing PAPR guest to resize their hash page table (HPT) during runtime. This patch makes use of that facility to allocate smaller HPTs by default. Specifically when a guest is aware of the HPT resize facility, qemu sizes the HPT to the initial memory size, rather than the maximum memory size on the assumption that the guest will resize its HPT if necessary for hot plugged memory. When the initial memory size is much smaller than the maximum memory size (a common configuration with e.g. oVirt / RHEV) then this can save significant memory on the HPT. If the guest does *not* advertise HPT resize awareness when it makes the ibm,client-architecture-support call, qemu resizes the HPT for maxmimum memory size (unless it's been configured not to allow such guests at all). For now we make that reallocation assuming the guest has not yet used the HPT at all. That's true in practice, but not, strictly, an architectural or PAPR requirement. If we need to in future we can fix this by having the client-architecture-support call reboot the guest with the revised HPT size (the client-architecture-support call is explicitly permitted to trigger a reboot in this way).

This patch implements hypercalls allowing a PAPR guest to resize its own hash page table. This will eventually allow for more flexible memory hotplug. The implementation is partially asynchronous, handled in a special thread running the hpt_prepare_thread() function. The state of a pending resize is stored in SPAPR_MACHINE->pending_hpt. The H_RESIZE_HPT_PREPARE hypercall will kick off creation of a new HPT, or, if one is already in progress, monitor it for completion. If there is an existing HPT resize in progress that doesn't match the size specified in the call, it will cancel it, replacing it with a new one matching the given size. The H_RESIZE_HPT_COMMIT completes transition to a resized HPT, and can only be called successfully once H_RESIZE_HPT_PREPARE has successfully completed initialization of a new HPT. The guest must ensure that there are no concurrent accesses to the existing HPT while this is called (this effectively means stop_machine() for Linux guests). For now H_RESIZE_HPT_COMMIT goes through the whole old HPT, rehashing each HPTE into the new HPT. This can have quite high latency, but it seems to be of the order of typical migration downtime latencies for HPTs of size up to ~2GiB (which would be used in a 256GiB guest). In future we probably want to move more of the rehashing to the "prepare" phase, by having H_ENTER and other hcalls update both current and pending HPTs. That's a project for another day, but should be possible without any changes to the guest interface. Signed-off-by: NDavid Gibson <david@gibson.dropbear.id.au>

This introduces stub implementations of the H_RESIZE_HPT_PREPARE and H_RESIZE_HPT_COMMIT hypercalls which we hope to add in a PAPR extension to allow run time resizing of a guest's hash page table. It also adds a new machine property for controlling whether this new facility is available. For now we only allow resizing with TCG, allowing it with KVM will require kernel changes as well. Finally, it adds a new string to the hypertas property in the device tree, advertising to the guest the availability of the HPT resizing hypercalls. This is a tentative suggested value, and would need to be standardized by PAPR before being merged.

Since commit 5c1da812 ("spapr: Remove unnecessary differences between hotplug and coldplug paths"), the CPU DT for the DRC is always allocated. This causes a memory leak for pseries-2.6 and older machine types, that don't support CPU hotplug and don't allocate DRCs for CPUs.

According to PAPR, the DR-indicator should only be valid for physical DRCs, not logical DRCs. At the moment we implement it for all DRCs, so restrict it to physical ones only. We move the state to the physical DRC subclass, which means adding some QOM boilerplate to handle the newly distinct type.

Most of the time, the state of a DRC object is contained in the single 'state' variable. However, during the transition from UNISOLATE to CONFIGURED state requires multiple calls to the ibm,configure-connector RTAS call to retrieve the device tree for the attached device. We need some extra state to keep track of where we're up to in delivering the device tree information to the guest. Currently that extra state is in a sPAPRConfigureConnectorState substructure which is only allocated when we're in the middle of the configure connector process. That sounds like a good idea, but the extra state is only two integers - on many platforms that will take up the same room as the (maybe NULL) ccs pointer even before malloc() overhead. Plus it's another object whose lifetime we need to manage. In short, it's not worth it. So, fold the sPAPRConfigureConnectorState substructure directly into the DRC object. Previously the structure was allocated lazily when the configure-connector call discovers it's not there. Now, we need to initialize the subfields pre-emptively, as soon as we enter UNISOLATE state. Although it's not strictly necessary (the field values should only ever be consulted when in UNISOLATE state), we try to keep them at -1 when in other states, as a debugging aid.

Each DRC has three fields describing its state: isolation_state, allocation_state and configured. At first this seems like a reasonable representation, since its based directly on the PAPR defined isolation-state and allocation-state indicators. However: * Only a few combinations of the two fields' values are permitted * allocation_state isn't used at all for physical DRCs * The indicators are write only so they don't really have a well defined current value independent of each other This replaces these variables with a single state variable, whose names and numbers are based on the diagram in LoPAPR section 13.4. Along with this we add code to check the current state on various operations and make sure the requested transition is permitted. Strictly speaking, this makes guest visible changes to behaviour (since we probably allowed some transitions we shouldn't have before). However, a hypothetical guest broken by that wasn't PAPR compliant, and probably wouldn't have worked under PowerVM.

'awaiting_release' indicates that the host has requested an unplug of the device attached to the DRC, but the guest has not (yet) put the device into a state where it is safe to complete removal. 1. Rename it to 'unplug_requested' which to me at least is clearer 2. Remove the ->release_pending() method used to check this from outside spapr_drc.c. The method only plausibly has one implementation, so use a plain function (spapr_drc_unplug_requested()) instead. 3. Remove it from the migration stream. Attempting to migrate mid-unplug is broken not just for spapr - in general management has no good way to determine if the device should be present on the destination or not. So, until that's fixed, there's no point adding extra things to the stream.

We currently ignore errors from the object_property_del() in spapr_drc_release(). But the only way that could fail is if the property doesn't exist, in which case it's a bug that we're in spapr_drc_release() at all. So change from ignoring to abort()ing on errors.

spapr_lmb_release() and spapr_core_release() call hotplug_handler_unplug() which after a bunch of indirection calls spapr_memory_unplug() or spapr_core_unplug(). But we already know which is the appropriate thing to call here, so we can just fold it directly into the release function. Once that's done, there's no need for an hc->unplug method in the spapr machine at all: since we also have an hc->unplug_request method, the hotplug core will never use ->unplug.

The awaiting_allocation flag in the DRC was introduced by aab99135 "spapr_drc: Prevent detach racing against attach for CPU DR", allegedly to prevent a guest crash on racing attach and detach. Except.. information from the BZ actually suggests a qemu crash, not a guest crash. And there shouldn't be a problem here anyway: if the guest has already moved the DRC away from UNUSABLE state, the detach would already be deferred, and if it hadn't it should be safe to detach it (the guest should fail gracefully when it attempts to change the allocation state). I think this was probably just a bandaid for some other problem in the state management. So, remove awaiting_allocation and associated code.

When migrating a guest which has already had devices hotplugged, libvirt typically starts the destination qemu with -incoming defer, adds those hotplugged devices with qmp, then initiates the incoming migration. This causes problems for the management of spapr DRC state. Because the device is treated as hotplugged, it goes into a DRC state for a device immediately after it's plugged, but before the guest has acknowledged its presence. However, chances are the guest on the source machine *has* acknowledged the device's presence and configured it. If the source has fully configured the device, then DRC state won't be sent in the migration stream: for maximum migration compatibility with earlier versions we don't migrate DRCs in coldplug-equivalent state. That means that the DRC effectively changes state over the migrate, causing problems later on. In addition, logging hotplug events for these devices isn't what we want because a) those events should already have been issued on the source host and b) the event queue should get wiped out by the incoming state anyway. In short, what we really want is to treat devices added before an incoming migration as if they were coldplugged. To do this, we first add a spapr_drc_hotplugged() helper which determines if the device is hotplugged in the sense relevant for DRC state management. We only send hotplug events when this is true. Second, when we add a device which isn't hotplugged in this sense, we force a reset of the DRC state - this ensures the DRC is in a coldplug-equivalent state (there isn't usually a system reset between these device adds and the incoming migration). This is based on an earlier patch by Laurent Vivier, cleaned up and extended.

The rtas_error_log structure is marked packed, which strongly suggests its precise layout is important to match an external interface. Along with that one could expect it to have a fixed endianness to match the same interface. That used to be the case - matching the layout of PAPR RTAS event format and requiring BE fields. Now, however, it's only used embedded within sPAPREventLogEntry with the fields in native order, since they're processed internally. Clear that up by removing the nested structure in sPAPREventLogEntry. struct rtas_error_log is moved back to spapr_events.c where it is used as a temporary to help convert the fields in sPAPREventLogEntry to the correct in memory format when delivering an event to the guest.

In racing situations between hotplug events and migration operation, a rtas hotplug event could have not yet be delivered to the source guest when migration is started. In this case the pending_events of spapr state need be transmitted to the target so that the hotplug event can be finished on the target. To achieve the minimal VMSD possible to migrate the pending_events list, this patch makes the changes in spapr_events.c: - 'log_type' of sPAPREventLogEntry struct deleted. This information can be derived by inspecting the rtas_error_log summary field. A new function called 'spapr_event_log_entry_type' was added to retrieve the type of a given sPAPREventLogEntry. - sPAPREventLogEntry, epow_log_full and hp_log_full were redesigned. The only data we're going to migrate in the VMSD is the event log data itself, which can be divided in two parts: a rtas_error_log header and an extended event log field. The rtas_error_log header contains information about the size of the extended log field, which can be used inside VMSD as the size parameter of the VBUFFER_ALOC field that will store it. To allow this use, the header.extended_length field must be exposed inline to the VMSD instead of embedded into a 'data' field that holds everything. With this in mind, the following changes were done: * a new 'header' field was added to sPAPREventLogEntry. This field holds a a struct rtas_error_log inline. * the declaration of the 'rtas_error_log' struct was moved to spapr.h to be visible to the VMSD macros. * 'data' field of sPAPREventLogEntry was renamed to 'extended_log' and now holds only the contents of the extended event log. * 'struct rtas_error_log hdr' were taken away from both epow_log_full and hp_log_full. This information is now available at the header field of sPAPREventLogEntry. * epow_log_full and hp_log_full were renamed to epow_extended_log and hp_extended_log respectively. This rename makes it clearer to understand the new purpose of both structures: hold the information of an extended event log field. * spapr_powerdown_req and spapr_hotplug_req_event now creates a sPAPREventLogEntry structure that contains the full rtas log entry. * rtas_event_log_queue and rtas_event_log_dequeue now receives a sPAPREventLogEntry pointer as a parameter instead of a void pointer. - the endianess of the sPAPREventLogEntry header is now native instead of be32. We can use the fields in native endianess internally and write them in be32 in the guest physical memory inside 'check_exception'. This allows the VMSD inside spapr.c to read the correct size of the entended_log field. - inside spapr.c, pending_events is put in a subsection in the spapr state VMSD to make sure migration across different versions is not broken. A small change in rtas_event_log_queue and rtas_event_log_dequeue were also made: instead of calling qdev_get_machine(), both functions now receive a pointer to the sPAPRMachineState. This pointer is already available in the callers of these functions and we don't need to waste resources calling qdev() again.

All the DRC subtypes explicitly list instance_size in TypeInfo (all as sizeof(sPAPRDRConnector). This isn't necessary, since if it's not listed it will be derived from the parent type. Worse, this is dangerous, because if a subtype is changed in future to have a larger structure, then subtypes of that subtype also need to have instance_size changed, or it will lead to hard to track memory corruption bugs.
