2009-05-21Eliminate --disable-gfx-check and make VNC default when SDL not availableAnthony Liguori
--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>

2009-05-20initialize struct sigevent before timer_createJean-Christophe Dubois
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.

2009-05-20Fix NULL alarm_timer pointer at exitJean-Christophe Dubois
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.)

2009-05-19Hardware convenience libraryPaul Brook
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. Big/Little endian is not handled because devices should not know or care about this to start with. Signed-off-by: Paul Brook <paul@codesourcery.com>

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.
