2011-03-21change all other clock references to use nanosecond resolution accessorsPaolo Bonzini68-268/+268
This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

2011-03-21add more helper functions with explicit milli/nanosecond resolutionPaolo Bonzini1-0/+23
The code doesn't make much sense right now, but it will as soon as timers will be able to scale their resolution arbitrarily. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2011-03-20Fix conversions from pointer to int and vice versaStefan Weil4-10/+10
Here the int values fds[0], sigfd, s, sock and fd are converted to void pointers which are later converted back to an int value. These conversions should always use intptr_t instead of unsigned long. They are needed for environments where sizeof(long) != sizeof(void *). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-03-15simpletrace: Move st_init() error reportingStefan Hajnoczi3-8/+9
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().

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

2011-03-12pc: fix wrong CMOS values for floppy drivesBlue Swirl1-1/+1
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 Weil2-8/+7
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.
