Detected by GCC 7's -Wformat-truncation.  snprintf writes at most
2 bytes here including the terminating NUL, so the result is

b612a49db2 sm501: Add some more missing registers
This is to allow clients to initialise these without failing as long
as no 2D engine function is called that would use the written value.
Saved values are not used yet (may get used when more of 2D engine is
added sometimes) and clients normally only write to most of these
registers, nothing is known to ever read them but they are documented
as read/write so also implement read for these.

6a2a5aae02 sm501: Fix hardware cursor
Rework HWC handling to simplify it and fix cursor not updating on
screen as needed. Previously cursor was not updated because checking
for changes in a line overrode the update flag set for the cursor but
fixing this is not enough because the cursor should also be updated if
its shape or location changes. Introduce hwc_invalidate() function to
handle that similar to other display controller models.

afef2e1d53 sm501: Fix device endianness
We only emulate the sysbus device in its default LE mode and PCI is LE
as well so specify this for registers and framebuffer memory.

Note that though the Linux kernel driver has code which claims to
handle both big and little endian, it is obviously bogus for 16 bit
and cannot be trusted as a source of information on the framebuffer
pixel format. This is our best guess about device behaviour based on
the specs and testing with MorphOS that is known to work on real HW.

6f663d7be9 qxl: add xres and yres properties
Add properties for the default display resolution, pass
on that information to the guest so the driver can use it.

Also move up qxl_crc32() function so we don't need a
forward declaration.

Additionally guest driver updates are needed so the
guest driver will actually pick this up, which will
probably land in linux kernel 4.12.

Drop dirty tracking code from the fifo rendering code path, it isn't

fec5e8c92b vga: make display updates thread safe.
The vga code clears the dirty bits *after* reading the framebuffer
memory.  So if the guest framebuffer updates hits the race window
between vga reading the framebuffer and vga clearing the dirty bits
vga will miss that update

Fix it by using the new memory_region_copy_and_clear_dirty()
memory_region_copy_get_dirty() functions.  That way we clear the
dirty bitmap before reading the framebuffer.  Any guest display
updates happening in parallel will be properly tracked in the
dirty bitmap then and the next display refresh will pick them up.

Problem triggers with mttcg only.  Before mttcg was merged tcg
never ran in parallel to vga emulation.  Using kvm will hide the
problem too, due to qemu operating on a userspace copy of the
kernel's dirty bitmap.

f3289f6f0f vga: add vga_scanline_invalidated helper
Add vga_scanline_invalidated helper to check whenever a scanline was
invalidated.  Add a sanity check to fix OOB read access for display
heights larger than 2048.

Only cirrus uses this, for hardware cursor rendering, so having this
work properly for the first 2048 scanlines only shouldn't be a problem
as the cirrus can't handle large resolutions anyway.  Also changing the
invalidated_y_table size would break live migration.

a703d3aef5 qxl: switch display on entering VGA
Since commit cd958edb1f, same size console resize is skipped. This
change broke QXL incoming migration in VGA mode,
qemu_spice_display_switch() is no longer called during qxl_post_load(),
because default message surface is of the same size, and during
displaychangelistener registration, PCIQXLDevice.mode is
QXL_MODE_UNDEFINED. This triggers a later crash on refresh:

==2634== Invalid read of size 4

One way to solve this is to explicitely call qemu_spice_display_switch()
