--disable-gfx-check predates VNC server support. It made sense back then because the only thing you could do without SDL was use -nographic mode or similar tricks. Since this is a very advanced mode of operation, gfx-check provided a good safety net for casual users. A casual user is very likely to use VNC to interact with a guest. In fact, it's often frustrating to install QEMU on a server and have to specify disable-gfx-check when you only want to use VNC. This patch eliminates disable-gfx-check and makes SDL behave like every other optional dependency. If SDL is not available, instead of failing ungracefully if no special options are specified, we default to -vnc localhost:0,to=99. When we do default to VNC, we also print a message to tell the user that we've done this include which port we're currently listening on. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

When qemu is run under valgrind, valgrind shows the following output on exit: ==3648== 1 errors in context 2 of 2: ==3648== Syscall param timer_create(evp) points to uninitialised byte(s) ==3648== at 0x54E936A: timer_create (in /lib/librt-2.9.so) ==3648== by 0x405DCF: dynticks_start_timer (vl.c:1549) ==3648== by 0x40A966: main (vl.c:1726) ==3648== Address 0x7fefffb34 is on thread 1's stack ==3648== Uninitialised value was created by a stack allocation ==3648== at 0x405D60: dynticks_start_timer (vl.c:1534) This patch is a simple fix to remove this potential problem.

This fixes a SIGSEGV error on qemu exit. Here is the valgrind output related to this error ==3648== Process terminating with default action of signal 11 (SIGSEGV) ==3648== Access not within mapped region at address 0x8 ==3648== at 0x40636B: host_alarm_handler (vl.c:1345) ==3648== by 0x52D807F: (within /lib/libpthread-2.9.so) ==3648== by 0x5C0A12E: tcsetattr (in /lib/libc-2.9.so) ==3648== by 0x4DD601: term_exit (qemu-char.c:700) ==3648== by 0x5B636EC: exit (in /lib/libc-2.9.so) ==3648== by 0x5B4B5AC: (below main) (in /lib/libc-2.9.so) This simple fix check for a valid pointer as host_alarm_handler is also called after alarm_timer is released in the exit path.

This text is no longer accurate. After the patch is applied, the generated version at http://www.nongnu.org/qemu/qemu-doc.html should be regenerated. This patch is also a candidate for the stable branch. (The URL above is probably generated from the stable branch anyways, so maybe it goes without saying.)

The only target dependency for most hardware is sizeof(target_phys_addr_t). Build these files into a convenience library, and use that instead of building for every target. Remove and poison various target specific macros to avoid bogus target dependencies creeping back in.

ARMv7 defines a new behavior for ARM data processing instructions compared to earlier architecture revisions; when the destination register is R15, a Branch and Exchange operation is executed rather than a simple Branch to the target address. This patch corrects the behavior of the emulation for the aforementioned operations. To be applied after applying the previous patch in this patch set.
