Switching the vnc server framebuffer to use 32bpp unconditionally turns the code bits which handle 8 and 16 bpp into dead code. Remove them. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

The vnc code uses *three* DisplaySurfaces: First is the surface of the actual QemuConsole, usually the guest screen, but could also be a text console (monitor/serial reachable via Ctrl-Alt-<nr> keys). This is left as-is. Second is the current server's view of the screen content. The vnc code uses this to figure which parts of the guest screen did _really_ change to reduce the amount of updates sent to the vnc clients. It is also used as data source when sending out the updates to the clients. This surface gets replaced by a pixman image. The format changes too, instead of using the guest screen format we'll use fixed 32bit rgb framebuffer and convert the pixels on the fly when comparing and updating the server framebuffer. Third surface carries the format expected by the vnc client. That isn't used to store image data. This surface is switched to PixelFormat and a boolean for bigendian byte order.

Currently it is inconstent, PixelFormat->amask is left unset whereas abits and amax and ashift are filled. As an alpha channel doesn't make sense for the vga framebuffer leave all alpha fields clear. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

With both text (curses) and graphics (vnc/sdl/spice/...) display active vga text mode emulation fails to update both correctly. Depending on whenever vga_update_text() or vga_draw_text() happens to be called first only the text display or only the graphics display will see display resolution changes and full redraws. Fix it by calling both text/gfx resize functions in both code paths and keep track of full screen redraws needed in VGACommonState fields. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Stop abusing displaysurface fields for text mode displays. (bpp = 0, width = cols, height = lines). Add flags to displaystate indicating whenever text mode display (curses) or gfx mode displays (sdl, vnc, ...) are present. Add separate displaychangelistener callbacks for text / gfx mode resize & updates. This allows to enable gfx and txt diplays at the same time and also paves the way for more cleanups in the future.

Also change the way the gui_timer is initialized: each time a displaychangelistener is registered or unregistered we'll check whether we need a timer (due to dpy_refresh callback being present) and if so setup a timer, otherwise zap it. This way the gui timer works correctly with displaychangelisteners coming and going. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Use the deposit op instead of and hardcoded bit field insertion. It allows the host to emit the corresponding instruction if available. At the same time remove the (lsb > msb) test. The MIPS64R2 instruction set manual says "Because of the instruction format, lsb can never be greater than msb, so there is no UNPREDICATABLE case for this instruction." (Bug reported as LP:1071149.)

The result of a division by 0, or a division of INT_MIN by -1 in the signed case, is unpredictable. Just replace 0 by 1 in that case so that it doesn't trigger a floating point exception on the host.

Load/store from helpers should be avoided as they are quite inefficient. Rewrite unaligned loads instructions using TCG and aligned loads. The number of actual loads operations to implement an unaligned load instruction is reduced from up to 8 to 1. Note: As we can't rely on shift by 32 or 64 undefined behaviour, the code loads already shift by one constants.

softfloat already has a few constants defined, use them instead of redefining them in target-mips. Rename FLOAT_SNAN32 and FLOAT_SNAN64 to FP_TO_INT32_OVERFLOW and FP_TO_INT64_OVERFLOW as even if they have the same value, they are technically different (and defined differently in the MIPS ISA).

For each FPU instruction that can trigger an FPU exception, to call call update_fcr31() after. Remove the manual NaN assignment in case of float to float operation, as softfloat is already taking care of that. However for float to int operation, the value has to be changed to the MIPS one. In the cvtpw_ps case, the two registers have to be handled separately to guarantee a correct final value in both registers.
