2012-04-07w64: Fix data type of tb_next and other variables used for host addressesStefan Weil3-23/+22
QEMU host addresses must use uintptr_t to be portable for hosts with an unusual size of long (w64). tb_jmp_offset is an uint16_t value, therefore the local variable offset in function tb_set_jmp_target was changed from unsigned long to uint16_t. The type cast to long in function tb_add_jump now also uses uintptr_t. For the bit operation used here, the signedness of the type cast does not matter. Some remaining unsigned long values are either only used for ARM assembler code or will be fixed in a later patch for PPC. v2: Fix signature of tb_find_pc in exec.c, too (hint from Blue Swirl, thanks). There remain lots of other long / unsigned long in exec.c which must be replaced by uintptr_t. This will be done in a separate patch. Here only one of these type casts is fixed. v3: Also fix signature of page_unprotect. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-04-07softfloat: roundAndPackInt{32, 64}: Don't assume int32 is 32 bitsPeter Maydell1-2/+2
Fix code in roundAndPackInt32 that assumed that int32 was only 32 bits, by simply using int32_t instead. Fix the parallel bug in roundAndPackInt64 as well, although that one is only theoretical since it's unlikely that int64 will ever be more than 64 bits.

Code in the float64_to_int32_round_to_zero() function was assuming that int32 would not be wider than 32 bits; this meant it might not correctly detect the overflow case. We take the simple approach of using int32_t. Also fix equivalent issues in the functions for other float sizes.

2012-04-07configure: require glib 2.12, 2.20 for mingw32Paolo Bonzini1-2/+10
These are pretty sane requirements to move forward with glib usage. 2.12 is the version found in RHEL/CentOS 5, and 2.20 is the first version to support g_poll. Without g_poll, we cannot integrate well with the glib main loop. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-04-07main-loop: replace WaitForMultipleObjects with g_pollPaolo Bonzini1-23/+17
On w32, glib implements g_poll using WaitForMultipleObjects or MsgWaitForMultipleObjects. This means that we can simplify our code by switching to g_poll, and at the same time prepare for adding back glib sources.

2012-04-07main-loop: interrupt wait when data arrives on a socketPaolo Bonzini3-25/+48
Right now, the main loop is not interrupted when data arrives on a socket. To fix this, register each socket to interrupt the main loop with WSAEventSelect. This does not replace select, it only communicates a change in socket state that requires a select call. Since the interrupt fires only once per recv call, or only once after a send call returns EWOULDBLOCK we can activate it on all events unconditionally. If QEMU is momentarily uninterested on some condition, the main loop will not busy wait. Instead, it may get one extra wakeup, but then it will ignore the condition until progress occurs and/or qemu_set_fd_handler is called to set a callback. At this point the condition will be tested via select and the callback will be invoked even if it is still disabled on the event.

2012-04-07main-loop: disable fd_set-based glib integration under w32Paolo Bonzini1-30/+33

2012-04-07main loop: use msec-based timeout in glib_select_fillPaolo Bonzini1-12/+10

2012-04-06Userspace ARM BE8 supportPaul Brook7-20/+86
Add support for ARM BE8 userspace binaries. i.e. big-endian data and little-endian code. In principle LE8 mode is also possible, but AFAIK has never actually been implemented/used. System emulation doesn't have any useable big-endian board models, but should in principle work once you fix that. Dynamic endianness switching requires messing with data accesses, preferably with TCG cooperation, and is orthogonal to BE8 support.

2012-04-06linux-user/arm/syscall_nr.h: Add syscall number for ppollPeter Maydell1-1/+1
The list of ARM syscall numbers was missing the entry for ppoll, which meant we were accidentally not providing it.

2012-04-06linux-user: reserve 4GB of vmem for 32-on-64Alexander Graf1-0/+11
When running 32-on-64 bit guests, we should always reserve as much virtual memory as we possibly can for the guest process, so it can never overlap with QEMU address space. Fortunately we already have the infrastructure for that. All that's missing is some sane default value to also make use of it!

2012-04-06linux-user: take RESERVED_VA into account for g2h_valid()Alexander Graf1-1/+2
When running with -R (RESERVED_VA > 0) all guest virtual addresses are within the [0..RESERVED_VA] range. Reflect this with g2h_valid() too so we can safely check for boundaries of our guest address space. This is required to have the /proc/self/maps code not show maps that aren't accessible from the guest process's point of view.
