2013-10-17icount: prepare the code for future races in calling qemu_clock_warpPaolo Bonzini
Computing the deadline of all vm_clocks is somewhat expensive and calls out to qemu-timer.c; two reasons not to do it in the seqlock's write-side critical section. This however opens the door for races in setting and reading vm_clock_warp_start. To plug them, we need to cover the case where a new deadline slips in between the call to qemu_clock_deadline_ns_all and the actual modification of the icount_warp_timer. Restrict changes to vm_clock_warp_start and the icount_warp_timer's expiration time, to only move them back (which would simply cause an early wakeup). If a vm_clock timer is cancelled while CPUs are idle, this might cause the icount_warp_timer to fire unnecessarily. This is not a problem, after it fires the timer becomes inactive and the next call to timer_mod_anticipate will be precise. In addition to this, we must deactivate the icount_warp_timer _before_ checking whether CPUs are idle. This way, if the "last" CPU becomes idle during the call to timer_del we will still set up the icount_warp_timer. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-10-17icount: reorganize icount_warp_rtPaolo Bonzini
To prepare for future code changes, move the increment of qemu_icount_bias outside the "if" statement. Also, hoist outside the if the check for timers that expired due to the "warping". The check is redundant when !runstate_is_running(), but doing it this way helps because the code that increments qemu_icount_bias will be a critical section.

2013-10-17icount: use cpu_get_icount() directlyPaolo Bonzini
This will help later when we will have to place these calls in a critical section, and thus call a version of cpu_get_icount() that does not take the lock. Reviewed-by: Alex Bligh <alex@alex.org.uk> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2013-10-17timer: make qemu_clock_enable sync between disable and timer's cbLiu Ping Fan
After disabling the QemuClock, we should make sure that no QemuTimers are still in flight. To implement that with light overhead, we resort to QemuEvent. The caller of disabling will wait on QemuEvent of each timerlist. Note, qemu_clock_enable(foo,false) can _not_ be called from timer's cb. Also, the callers of qemu_clock_enable() should be protected by the BQL. Signed-off-by: Liu Ping Fan <pingfank@linux.vnet.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-10-17qemu-thread: add QemuEventPaolo Bonzini
This emulates Win32 manual-reset events using futexes or conditional variables. Typical ways to use them are with multi-producer, single-consumer data structures, to test for a complex condition whose elements come from different threads: for (;;) { qemu_event_reset(ev); ... test complex condition ... if (condition is true) { break; } qemu_event_wait(ev); } Or more efficiently (but with some duplication): ... evaluate condition ... while (!condition) { qemu_event_reset(ev); ... evaluate condition ... if (!condition) { qemu_event_wait(ev); ... evaluate condition ... } } QemuEvent provides a very fast userspace path in the common case when no other thread is waiting, or the event is not changing state.

2013-10-17timer: protect timers_state's clock with seqlockLiu Ping Fan
QEMU_CLOCK_VIRTUAL may be read outside BQL. This will make its foundation, i.e. cpu_clock_offset exposed to race condition. Using private lock to protect it. After this patch, reading QEMU_CLOCK_VIRTUAL is thread safe unless use_icount is true, in which case the existing callers still rely on the BQL.

2013-10-17e820: pass high memory too.Gerd Hoffmann
We have a fw_cfg entry to pass e820 entries from qemu to the firmware. Today it's used to pass reservations only. This patch makes qemu pass entries for RAM too. This allows to pass RAM sizes larger than 1TB to the firmware and it will also allow to pass non-contignous memory ramges should we decide to implement that some day, say for our virtual numa nodes. Obviously this needs some extra care to not break existing firware. SeaBIOS loads the entries and happily adds them without looking at the type. Which is problematic for memory below 4g as this will overwrite reservations added for bios memory etc. For memory above 4g it works just fine, seabios will merge the entry derived from cmos with the one loaded from fw_cfg. OVMF doesn't look at the fw_cfg e820 table. coreboot doesn't look at the fw_cfg e820 table.

2013-10-17spice: fix multihead supportGerd Hoffmann
This patch fixes spice display initialization to handle multihead properly. spice-core now keeps track of which QemuConsole has a spice display channel attached to it and which has not. It also manages display channel ids. spice-display looks at all QemuConsoles and will pick up any graphic console not yet bound to a spice channel (which in practice are all non-qxl graphic devices). Result is that (a) you'll get a spice client window for each graphical device now (first only without this patch), and (b) mixing qxl and non-qxl vga cards works properly.

2013-10-17Fix VNC SASL authentication when using a QXL deviceChristophe Fergeau
ui/vnc.c:vnc_display_open() and spice-server/server/reds.c:do_spice_init() are both calling sasl_server_init(). If spice_server_set_sasl_appname() hasn't been called, spice-server will call it with "spice" as an appname, causing cyrus-sasl to try to use a /etc/sasl2/spice.conf config file rather than the /etc/sasl2/qemu.conf file that QEMU uses. When using -spice sasl on the command line, QEMU properly calls spice_server_set_sasl_appname() to set the SASL appname as "qemu", but when using a QXL device without using SPICE, spice_server_init() is called from qemu_spice_add_interface() without setting the appname to "qemu", which then causes the VNC code to try to use spice.conf instead of qemu.conf.

2013-10-14i386: ACPI table generation code from seabiosMichael S. Tsirkin
This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.
