This catches the situation that is described in the bug report at https://bugs.launchpad.net/qemu/+bug/865518 and goes like this: $ qemu-img create -f qcow2 huge.qcow2 $((1024*1024))T Formatting 'huge.qcow2', fmt=qcow2 size=1152921504606846976 encryption=off cluster_size=65536 lazy_refcounts=off $ qemu-io /tmp/huge.qcow2 -c "write $((1024*1024*1024*1024*1024*1024 - 1024)) 512" Segmentation fault With this patch applied the segfault will be avoided, however the case will still fail, though gracefully: $ qemu-img create -f qcow2 /tmp/huge.qcow2 $((1024*1024))T Formatting 'huge.qcow2', fmt=qcow2 size=1152921504606846976 encryption=off cluster_size=65536 lazy_refcounts=off qemu-img: The image size is too large for file format 'qcow2' Note that even long before these overflow checks kick in, you get insanely high memory usage (up to INT_MAX * sizeof(uint64_t) = 16 GB for the L1 table), so with somewhat smaller image sizes you'll probably see qemu aborting for a failed g_malloc(). If you need huge image sizes, you should increase the cluster size to the maximum of 2 MB in order to get higher limits.

Commit 9697f5d2 "gtk: custom cursor support" introduced unconditional usage of gdk_display_warp_pointer(). This function is marked as deprecated since GTK-3.0, and triggers warning (error with -Werror) during compilation. Conditionally change gdk_display_warp_pointer() method usage to gdk_device_warp usage, as suggested by compiler.

This reverts commit 9953f882. While Markus's analysis is entirely correct, there are 1.6 patches that fix the bug for real and without requiring machine type hacks. Let's think of the children who will have to read this code, and avoid a complicated mess of semantics that differ between <1.5, 1.5, and >1.5.

Cast debugging can have a substantial cost (20% or more). Instead of adding special-cased "fast casts" in the hot paths, we can just disable it in releases. The tracing facilities we just added make it easier to analyze those problems that cast debugging would reveal.

由 Hans de Goede 提交于
With a SPICE_DISPLAY_CAP_MONITORS_CONFIG capable client, the client needs to know what part of the primary to use for each monitor. If the guest driver does not support this, the server sends messages to the client for a single monitor spanning the entire primary. As soon as the guest calls spice_qxl_monitors_config_async once, the server sets the red_worker driver_has_monitors_config flag and stops doing this. This is a problem when the driver gets unloaded, for example after a reboot or when switching to a text vc with usermode mode-setting under Linux. To reproduce this start a multi-mon capable Linux guest which uses usermode mode-setting and then once X has started switch to a text vc. Note how the client window does not only not resize, if you try to resize it manually you always keep blackborders since the aspect is wrong. This patch calls a new spice-server method called spice_qxl_driver_unload which clears the driver_has_monitors_config flag inside the server, thereby fixing this.

When running an L=1 cmp instruction on a 64bit PPC CPU with SF off, it still behaves identical to what it does when SF is on. Remove the implicit difference in the code. Also, on most 32bit CPUs we should always treat the compare as 32bit compare, as the CPU will ignore the L bit. This is not true for e500mc, but that's up for a different patch.
