If the memory size given on the command line is equal to the maximum size of memory defined by the hardware, there is no "empty slot" after physical memory. The following command qemu-system-sparc -m 256 raised an assertion: exec.c:2614: cpu_register_physical_memory_offset: Assertion `size' failed This can be fixed either at the caller side (don't call empty_slot_init) or in empty_slot_init (do nothing) when size == 0. The second solution was choosen here because it is more robust. Signed-off-by: NStefan Weil <weil@mail.berlios.de>

The previous patch however is not enough, because if the virtual CPU goes to sleep waiting for a future timer interrupt to wake it up, qemu deadlocks. The timer interrupt never comes because time is driven by icount, but the vCPU doesn't run any insns. You could say that VCPUs should never go to sleep in icount mode if there is a pending vm_clock timer; rather time should just warp to the next vm_clock event with no sleep ever taking place. Even better, you can sleep for some time related to the time left until the next event, to avoid that the warps are too visible externally; for example, you could be sending network packets continously instead of every 100ms. This is what this patch implements. qemu_clock_warp is called: 1) whenever a vm_clock timer is adjusted, to ensure the warp_timer is synchronized; 2) at strategic points in the CPU thread, to make sure the insn counter is synchronized before the CPU starts running. In any case, the warp_timer is disabled while the CPU is running, because the insn counter will then be making progress on its own.

The correct fix for -icount is to consider the biggest difference between iothread and non-iothread modes. In the traditional model, CPUs run _before_ the iothread calls select (or WaitForMultipleObjects for Win32). In the iothread model, CPUs run while the iothread isn't holding the mutex, i.e. _during_ those same calls. So, the iothread should always block as long as possible to let the CPUs run smoothly---the timeout might as well be infinite---and either the OS or the CPU thread itself will let the iothread know when something happens. At this point, the iothread wakes up and interrupts the CPU. This is exactly the approach that this patch takes: when cpu_exec_all returns in -icount mode, and it is because a vm_clock deadline has been met, it wakes up the iothread to process the timers. This is really the "bulk" of fixing icount. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Tested-by: NEdgar E. Iglesias <edgar.iglesias@gmail.com> Signed-off-by: NEdgar E.

Implement the 'media' sub-command of the GET_EVENT_STATUS_NOTIFICATION command. This helps us report tray open, tray closed, no media, media present states to the guest. Newer Linux kernels (2.6.38+) rely on this command to revalidate discs after media change. This patch also sends out tray open/closed status to the guest driver when requested e.g. via the CDROM_DRIVE_STATUS ioctl (thanks Markus). Without such notification, the guest and qemu's tray open/close status was frequently out of sync, causing installers like Anaconda detecting no disc instead of tray open, confusing them terribly.
