2013-10-31integrator: fix Linux boot failure by emulating dbg regionAlex Bennée
Commit 9b8c69243 (since reverted) broke the ability to boot the kernel as the value returned by unassigned_mem_read returned non-zero and left the kernel looping forever waiting for it to change (see integrator_led_set in the kernel code). Relying on a varying implementation detail is incorrect anyway so this introduces a basic stub of a memory region for the debug/LED section on the integrator board.

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.

2013-10-17seqlock: introduce read-write seqlockPaolo Bonzini
Seqlock implementation for QEMU. Usage idiom reader: do { start = seqlock_read_begin(&sl); ... } while (seqlock_read_retry(&sl, start)); writer: seqlock_write_lock(&sl); ... seqlock_write_unlock(&sl); initialization: seqlock_init(QemuSeqLock *sl, QemuMutex *mutex) mutex could be NULL if the caller will provide its own protection for concurrent write sides (typically using the BQL).

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.

phys_mem_alloc and its assigned values qemu_anon_ram_alloc and legacy_s390_alloc must have identical argument lists. legacy_s390_alloc uses the size parameter to call mmap, so size_t is good enough for all of them.

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.

2013-10-11Mostly revert "qemu-help: Sort devices by logical functionality"Markus Armbruster
This reverts most of commit 3d1237fb2ab4edb926c717767bb5e31d6053a7c5. The commit claims to sort the output of "-device help" "by functionality rather than alphabetical". Issues: * The output was unsorted before, not alphabetically sorted. Misleading, but harmless enough. * The commit doesn't just sort the output of "-device help" as it claims, it adds categories to each line of "-device help", and it prints devices once per category. In particular, devices without a category aren't shown anymore. Maybe such devices should not exist, but they do. Regression. * Categories are also added to the output of "info qdm". Silent change, not nice. Output remains unsorted, unlike "-device help". I'm going to reimplement the feature we actually want, without the warts. Reverting the flawed commit first should make it easier to review. However, I can't revert it completely, since DeviceClass member categories has been put to use. So leave that part in.
