2017-10-23migration: add bitmap for received pageAlexey Perevalov
This patch adds ability to track down already received pages, it's necessary for calculation vCPU block time in postcopy migration feature, and for recovery after postcopy migration failure. Also it's necessary to solve shared memory issue in postcopy livemigration. Information about received pages will be transferred to the software virtual bridge (e.g. OVS-VSWITCHD), to avoid fallocate (unmap) for already received pages. fallocate syscall is required for remmaped shared memory, due to remmaping itself blocks ioctl(UFFDIO_COPY, ioctl in this case will end with EEXIT error (struct page is exists after remmap). Bitmap is placed into RAMBlock as another postcopy/precopy related bitmaps.

2017-10-23migration: clean up xbzrle cache init/destroyPeter Xu
Let's further simplify ram_init_all() and ram_save_cleanup() by abstract all the XBZRLE related codes into their own functions. When allocating xbzrle cache, we are always very careful on -ENOMEM; which makes sense. Replacing the last g_malloc0() with g_try_malloc0(), then refactor the logic a bit.

2017-10-23ps2: fix scancodes sent for Alt-Print key combination (aka SysRq)Daniel P. Berrange
The 'Print' key is special in the AT set 1 / set 2 scancode definitions. An unmodified 'Print' key is supposed to send AT Set 1: e0 2a e0 37 (Down) e0 b7 e0 aa (Up) AT Set 2: e0 12 e0 7c (Down) e0 f0 7c e0 f0 12 (Up) which QEMU gets right. When pressed in combination with the 'Alt_L' or 'Alt_R' keys (which signify SysRq), the scancodes are required to follow a different scheme. With Alt_L, the expected sequences are AT set 1: 38, 54 (Down) d4, b8 (Up) AT set 2: 11, 84 (Down) f0 84, f0 11 (Up) And with Alt_R AT set 1: e0 38, 54 (Down) d4, e0 b8 (Up) AT set 2: e0 11, 84 (Down) f0 84, f0 e0 11 (Up) It is actually slightly more complicated than that, because (according results of 'showkey -s', keyboards will in fact first release the currently pressed modifier before sending the sequence above (which effectively re-presses & then releases the modifier) and finally re-press the original modifier afterwards. IOW, with Alt_L we need to send AT set 1: b8, 38, 54 (Down) d4, b8, 38 (Up) AT set 2: f0 11, 11, 84 (Down) f0 84, f0 11, 11 (Up) And with Alt_R AT set 1: e0 b8, e0 38, 54 (Down) d4, e0 b8, e0 38 (Up) AT set 2: e0 f0 11, e0 11, 84 (Down) f0 84, e0 f0 11, e0 11 (Up) The AT set 3 scancodes have no special handling for Alt-Print. Rather than fixing the handling of the 'print' key in the ps2 driver to consider the Alt modifiers, way back, a patch was commited that defined an extra 'sysrq' key name: commit f2289cb6924afc97b2a75d21bfc9217024d11741 Author: balrog <balrog@c046a42c-6fe2-441c-8c8c-71466251a162> Date: Wed Jun 4 10:14:16 2008 +0000 Add sysrq to key names known by "sendkey".

Signed-off-by: Ryan Harper <ryanh@us.ibm.com> With this patch QEMU would send AT set 1: 38, 54 (Down) d4, b8 (Up) AT set 2: 11, 84 (Down) f0 84, f0 11 (Up) but this doesn't match what actual real keyboards send, as it is not releasing the original modifier & pressing it again afterwards. In addition the original problem remains, and a new problem was added: - The sequence 'alt-print-t' is still broken, acting as if 'print-t' was requested - The sequence 'sysrq-t' is broken, injecting an undefine scancode sequence tot he guest os (bare 0x54) To deal with this mess we make these changes to the ps2 code, so that we track the state of modifier keys (Alt, Shift, Ctrl - both left & right). Then we can vary what scancodes are sent for Q_KEY_CODE_PRINT according to the Alt key modifier state Interestingly, it appears that of operating systems I've checked (Linux, FreeBSD and OpenSolaris), none of them actually bother to validate the full sequences for a unmodified 'Print' key. They all just ignore the leading "e0 2a" and trigger based off "e0 37" alone. The latter two byte sequence is what keyboards send with 'Print' is combined with 'Shift' or 'Ctrl' modifiers.

2017-10-23configure: disable qemu-keymap for linux-user qemuLaurent Vivier
We don't need qemu-keymap when we build only linux-user qemu. When we compile in static mode, the libxkbcommon is detected by configure if the shared one is available, but cannot be linked if the static version is not available. As we don't need it for qemu-linux-user, and we generally need a static link to use it in a chroot, disable qemu-keymap in this case.

2017-10-21openrisc: Only kick cpu on timeout, not on updateStafford Horne
Previously we were kicking the cpu on every update. This caused problems noticeable in SMP configurations where one CPU got pinned continuously servicing timer exceptions. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Stafford Horne <shorne@gmail.com>
2017-10-21openrisc: Initial SMP supportStafford Horne
Wire in ompic and add basic support for SMP. The OpenRISC is special in that interrupts for devices are routed to each core's PIC. This is achieved using the qemu_irq_split utility, but this currently limits OpenRISC to 2 cores. This models the reference architecture described in the OpenRISC spec 1.2 proposal. https://github.com/stffrdhrn/doc/raw/arch-1.2-proposal/openrisc-arch-1.2-rev0.pdf The changes to the intialization of the sim include: CPU Reset o Reset each cpu to the bootstrap PC rather than only a single cpu as done before. o During Kernel loading the bootstrap PC is saved in a static global. Network Initialization o Connect the interrupt to each CPU o Use more simple sysbus_mmio_map() rather than memory_region_add_subregion() Sim Initialization o Initialize the pic and tick timer per cpu o Wire in the OMPIC if SMP is enabled o Wire the serial irq to each CPU using qemu_irq_split() Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Stafford Horne <shorne@gmail.com>
2017-10-21openrisc/cputimer: Perparation for MulticoreStafford Horne
In order to support multicore system we move some of the previously static state variables into the state of each core. On the other hand in order to allow timers to be synced between each code the ttcr (tick timer count register) is moved out of the core. This is not as per real hardware spec which has a separate timer counter per core, but it seems the most simple way to keep each clock in sync.

2017-10-21target/openrisc: Make coreid and numcores variableStafford Horne
Previously coreid and numcores were hard coded as 0 and 1 respectively as OpenRISC QEMU did not have multicore support. Multicore support is now being added so these registers need to have configured values. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Stafford Horne <shorne@gmail.com>
