2016-10-24char: remove explicit_be_open from CharDriverStateMarc-André Lureau
It's only used in qmp_chardev_add(), so use a create() argument instead. Also switched to typedef functions for CharDriverParse/CharDriverCreate.

2016-10-24char: replace avail_connectionsMarc-André Lureau
No need to count the users of a CharDriverState, it can rely on the fact of whether there is a CharBackend associated or if there is enough space in the muxer. Simplify and fold chr_mux_new_fe() in qemu_chr_fe_init() since there is a single user now. Also switch from fprintf to raising error instead.

2016-10-24char: remove unused qemu_chr_fe_eventMarc-André Lureau
I introduced this function in d61b0c9a2f7f, but it isn't used. Furthermore, it was incomplete, as it would need to translate QEMU chr events to Spice port events.

2016-10-24char: move front end handlers in CharBackendMarc-André Lureau
Since the hanlders are associated with a CharBackend, rather than the CharDriverState, it is more appropriate to store in CharBackend. This avoids the handler copy dance in qemu_chr_fe_set_handlers() then mux_chr_update_read_handler(), by storing the CharBackend pointer directly. Also a mux CharDriver should go through mux->backends[focused], since chr->be will stay NULL. Before that, it was possible to call chr->handler by mistake with surprising results, for ex through qemu_chr_be_can_write(), which would result in calling the last set handler front end, not the one with focus.

2016-10-24char: make some qemu_chr_fe skip if no driverMarc-André Lureau
In most cases, front ends do not care about the side effect of CharBackend, so we can simply skip the checks and call the qemu_chr_fe functions even without associated CharDriver.

2016-10-24char: replace qemu_chr_claim/release with qemu_chr_fe_init/deinitMarc-André Lureau
Now that all front end use qemu_chr_fe_init(), we can move chardev claiming in init(), and add a function deinit() to release the chardev and cleanup handlers. The qemu_chr_fe_claim_no_fail() for property are gone, since the property will raise an error instead. In other cases, where there is already an error path, an error is raised instead. Finally, other cases are handled by &error_abort in qemu_chr_fe_init().

2016-10-24char: introduce CharBackendMarc-André Lureau
This new structure is meant to keep the details associated with a char driver usage. On initialization, it gets a tag from the mux backend. It can change its handlers thanks to qemu_chr_fe_set_handlers(). This structure is introduced so that all frontend will be moved to hold and use a CharBackend. This will allow to better track char usage and allocation, and help prevent some memory leaks or corruption.

2016-10-24mux: split mux_chr_update_read_handler()Marc-André Lureau
Make qemu_chr_add_handlers_full() aware of mux handling. This allows introduction of a tag associated with the fe handlers and a qemu_chr_set_handlers() function to set the handler for a particular tag. That will allow to get rid of qemu_chr_add_handlers*() in later changes, in favor of qemu_chr_fe_set_handler(). To this end, chr_update_read_handler callback is enhanced with a tag argument, and mux_chr_update_read_handler() is splitted in new functions: mux_chr_new_handler_tag(), mux_chr_set_handlers(), mux_set_focus().

This speeds up MEMORY_LISTENER_CALL noticeably. Right now, with many PCI devices you have N regions added to M AddressSpaces (M = # PCI devices with bus-master enabled) and each call looks up the whole listener list, with at least M listeners in it. Because most of the regions in N are BARs, which are also roughly proportional to M, the whole thing is O(M^3). This changes it to O(M^2), which is the best we can do without rewriting the whole thing. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-10-24qemu-thread: use acquire/release to clarify semantics of QemuEventPaolo Bonzini
Do not use the somewhat mysterious atomic_mb_read/atomic_mb_set, instead make sure that the operations on QemuEvent are annotated with the desired acquire and release semantics. In particular, qemu_event_set wakes up the waiting thread, so it must be a release from the POV of the waker (compare with qemu_mutex_unlock). And it actually needs a full barrier, because that's the only thing that provides something like a "load-release".

iSER is a new transport layer supported in Libiscsi, iSER provides a zero-copy RDMA capable interface that can improve performance. In order to use the new iSER transport one need to have RDMA supported HW and to choose iser as the protocol name in Libiscsi URI.

Otherwise, reads of more than 2GB fail. Until commit 7bbca9e290a9c7c217b5a24fc6094e91e54bd05d, reads of 2^41 bytes succeeded at least theoretically. In fact, pdiscard ought to receive a 64-bit integer as the count for the same reason. Reported by Coverity.

2016-10-23kvm-all: don't use stale dbg_data->cpuAlex Bennée
The changes to run_on_cpu and friends mean that all helpers are passed the CPUState of vCPU they are running on. The conversion missed the field in commit e0eeb4a21a3ca4b296220ce4449d8acef9de9049 which introduced bugs.
