2019-09-25cputlb: Move NOTDIRTY handling from I/O path to TLB pathRichard Henderson
Pages that we want to track for NOTDIRTY are RAM. We do not really need to go through the I/O path to handle them.

2019-09-25exec: Adjust notdirty tracingRichard Henderson
The memory_region_tb_read tracepoint is unreachable, since notdirty is supposed to apply only to writes. The memory_region_tb_write tracepoint is mis-named, because notdirty is not only used for TB invalidation. It is also used for e.g. VGA RAM updates and migration. Replace memory_region_tb_write with memory_notdirty_write_access, and place it in memory_notdirty_write_prepare where it can catch all of the instances. Add memory_notdirty_set_dirty to log when we no longer intercept writes to a page.

2019-09-24xen-bus: only set the xen device frontend state if it is missingMark Syms
Some toolstack implementations will set the frontend xenstore keys to Initialising which will then trigger the in guest PV drivers to begin initialising and some implementations will then set their state to Closing. If this has occurred then device realize must not overwrite the frontend keys as then the handshake will stall.

2019-09-24xen-block: treat XenbusStateUnknown the same as XenbusStateClosedPaul Durrant
When a frontend gracefully disconnects from an offline backend, it will set its own state to XenbusStateClosed. The code in xen-block.c correctly deals with this and sets the backend into XenbusStateClosed. Unfortunately it is possible for toolstack to actually delete the frontend area before the state key has been read, leading to an apparent frontend state of XenbusStateUnknown. This prevents the backend state from transitioning to XenbusStateClosed and hence leaves it limbo. This patch simply treats a frontend state of XenbusStateUnknown the same as XenbusStateClosed, which will unblock the backend in these circumstances.

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.

2019-09-24xen / notify: introduce a new XenWatchList abstractionPaul Durrant
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.

2019-09-23audio: api for mixeng code free backendsKővágó, Zoltán
This will make it possible to skip mixeng with audio playback and recording, allowing us to free ourselves from the limitations of the current mixeng (stereo, int64 samples only). In this case, HW and SW voices will be essentially the same, for every SW voice we will create a HW voice, since we can no longer mix multiple voices together. Some backends expect us to call a function when we have data ready write()/read() style, while others provide a buffer and expects us to directly write/read it, so for optimal performance audio_pcm_ops provide methods for both cases. Previously backends asked mixeng for more data in run_out/run_it, now instead mixeng or the frontends will call the backends, so that's why two sets of functions required. audio.c contains glue code between the two styles, so backends only ever have to implement one style and frontends are free to call whichever is more convenient for them.

Let's add a test that especially verifies that no data will be touched in case we cross page boundaries and one page access triggers a fault. Before the fault-safe handling fixes, the test failes with: TEST mvc on s390x data modified during a fault make[2]: *** [../Makefile.target:116: run-mvc] Error 1 Acked-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: David Hildenbrand <david@redhat.com>
