2011-03-19w32: Add missing functions qemu_mutex_destroy, qemu_cond_destroyStefan Weil
These functions were missing in commit 9257d46d55f1fe4e8209be9a6870e339ac3266fe. Both functions are needed for compilations with configuration --enable-vnc-thread.

2011-03-15simpletrace: Move st_init() error reportingStefan Hajnoczi
User emulator builds do not have error_report() so it should not be used by simpletrace.c. In fact, error reporting inside simpletrace.c is inappropriate and should be done by the caller instead. This patch moves st_init() error reporting out to its caller, vl.c:main().

2011-03-13do not use timedwait on qemu_halt_condPaolo Bonzini
The following conditions can cause cpu_has_work(env) to become true: - env->queued_work_first: run_on_cpu is already kicking the VCPU - env->stop = 1: pause_all_vcpus is already kicking the VCPU - env->stopped = 0: resume_all_vcpus is already kicking the VCPU - vm_running = 1: vm_start is calling resume_all_vcpus - env->halted = 0: see previous patch - qemu_cpu_has_work(env): when it becomes true, board code should set env->halted = 0 too.

2011-03-13Refactor thread retrieval and checkJan Kiszka
We have qemu_cpu_self and qemu_thread_self. The latter is retrieving the current thread, the former is checking for equality (using CPUState). We also have qemu_thread_equal which is only used like qemu_cpu_self. This refactors the interfaces, creating qemu_cpu_is_self and qemu_thread_is_self as well ass qemu_thread_get_self.

Index 75 is one too large for AR_TABLE[75], DR_TABLE[75].

2011-03-12pc: fix wrong CMOS values for floppy drivesBlue Swirl
Before commit 63ffb564dca94f8bda01ed6d209784104630a4d2, states for floppy drives were calculated in fdc.c:fd_revalidate(). There it is also considered whether a disk is inserted or not. The commit didn't copy the logic completely to pc.c, which caused a regression. Fix by adding the same check also to pc.c.

2011-03-10vnc: Fix stack corruption and other bitmap related bugsStefan Weil
Commit bc2429b9174ac2d3c56b7fd35884b0d89ec7fb02 introduced a severe bug (stack corruption). bitmap_clear was called with a wrong argument which caused out-of-bound writes to the local variable width_mask. This bug was detected with QEMU running on windows. It also occurs with wine: *** stack smashing detected ***: terminated wine: Unhandled illegal instruction at address 0x6115c7 (thread 0009), starting debugger... The bug is not windows specific! Instead of fixing the wrong parameter value, bitmap_clear(), bitmap_set and width_mask were removed, and bitmap_intersect() was replaced by !bitmap_empty(). The new operation is much shorter and equivalent to the old operations. The declarations of the dirty bitmaps in vnc.h were also wrong for 64 bit hosts because of a rounding effect: for these hosts, VNC_MAX_WIDTH is no longer a multiple of (16 * BITS_PER_LONG), so the rounded value of VNC_DIRTY_WORDS was too small. Fix both declarations by using the macro which is designed for this purpose.

2011-03-10Fix performance regression in qemu_get_ram_ptrVincent Palatin
When the commit f471a17e9d869df3c6573f7ec02c4725676d6f3a converted the ram_blocks structure to QLIST, it also removed the conditional check before switching the current block at the beginning of the list. In the common use case where ram_blocks has a few blocks with only one frequently accessed (the main RAM), this has a performance impact as it performs the useless list operations on each call (which are on a really hot path). On my machine emulation (ARM on amd64), this patch reduces the percentage of CPU time spent in qemu_get_ram_ptr from 6.3% to 2.1% in the profiling of a full boot.
