2018-06-20vga: fix region calculationGerd Hoffmann
Typically the scanline length and the line offset are identical. But in case they are not our calculation for region_end is incorrect. Using line_offset is fine for all scanlines, except the last one where we have to use the actual scanline length.

2018-06-20qxl: fix local renderer crashGerd Hoffmann
Make sure we only ask the spice local renderer for display updates in case we have a valid primary surface. Without that spice is confused and throws errors in case a display update request (triggered by screendump for example) happens in parallel to a mode switch and hits the race window where the old primary surface is gone and the new isn't establisted yet.

2018-02-12vga: check the validation of memory addr when draw textlinzhecheng
Start a vm with qemu-kvm -enable-kvm -vnc :66 -smp 1 -m 1024 -hda redhat_5.11.qcow2 -device pcnet -vga cirrus, then use VNC client to connect to VM, and excute the code below in guest OS will lead to qemu crash: int main() { iopl(3); srand(time(NULL)); int a,b; while(1){ a = rand()%0x100; b = 0x3c0 + (rand()%0x20); outb(a,b); } return 0; } The above code is writing the registers of VGA randomly. We can write VGA CRT controller registers index 0x0C or 0x0D (which is the start address register) to modify the the display memory address of the upper left pixel or character of the screen. The address may be out of the range of vga ram. So we should check the validation of memory address when reading or writing it to avoid segfault.

2017-10-17vga: handle cirrus vbe mode wraparounds.Gerd Hoffmann
Commit "3d90c62548 vga: stop passing pointers to vga_draw_line* functions" is incomplete. It doesn't handle the case that the vga rendering code tries to create a shared surface, i.e. a pixman image backed by vga video memory. That can not work in case the guest display wraps from end of video memory to the start. So force shadowing in that case. Also adjust the snapshot region calculation. Can trigger with cirrus only, when programming vbe modes using the bochs api (stdvga, also qxl and virtio-vga in vga compat mode) wrap arounds can't happen.

2017-07-25hw/display/sm501: Don't use vmstate_register_ram_global()Peter Maydell
The sm501 device uses vmstate_register_ram_global() to register its memory region for migration. This means it gets a name that is assumed to be global to the whole system, which in turn means that if you create two of the device we assert because of the duplication: qemu-system-ppc -device sm501 -device sm501 RAMBlock "sm501.local" already registered, abort! Aborted (core dumped) Changing this to just use memory_region_init_ram()'s automatic registration of the memory region with a device-local name fixes this. The downside is that it breaks migration compatibility, but luckily we only added migration support to this device in the 2.10 release cycle so we haven't released a QEMU version with the broken implementation.
