Hi,
First round of pixman patches for qemu, so we have something concrete to
discuss. Applies on top of the "console cleanups" patch series posted a
few days ago.
The long-term goal is to stop reinventing the wheel over and over when
it comes to pixel manipulation and to use pixman instead. This patch
series is a start. It switches a central data structure
(DisplaySurface) over to pixman, so the ui code can easily use pixman
to manipulate pixel data. It also collects some low-hanging fruit to
show pixman in action.
Comments?
cheers,
Gerd
Gerd Hoffmann (14):
console: remove DisplayAllocator
pixman: add submodule
pixman: windup in configure & makefiles
pixman: helper functions
pixman: add pixman image to DisplaySurface
console: make qemu_alloc_display static
console: don't set PixelFormat alpha fields for 32bpp
qxl: stop direct access to DisplaySurface fields.
vga: stop direct access to DisplaySurface fields.
pixman: switch screendump function.
pixman/vnc: use pixman images in vnc.
pixman/vnc: remove rgb_prepare_row* functions
pixman/vnc: remove dead code.
pixman: drop obsolete fields from DisplaySurface

Add pixman submodule as fallback for old distros.
Picking version 0.18.4. This is shipped by rhel6
and also the minimum version needed by spice so this
should serve well as baseline.

Surfaces are now allocated using pixman. DisplaySurface gets new
struct fields with pixman image and data. DisplayChangeListeners
can easily start using pixman now.

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.

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

Actually the alpha mask was left to 0 on purpose to ignore it.
At the same time we set amax, ashift and abits to signal the presence of
an alpha byte in the pixel format.

Is this really a good idea?
It is very common for a vnc client to ask for 16 or 8 bpp on slow
connections.

Hmm? I still don't see t he point of the current mix. Either the byte
is alpha or it is unused ...

The 16bpp modes (guest video modes) are slowly dying, so I think it is
best to operate at 32bpp internally. First because we don't need to
convert when reading the guest framebuffer. Second the format is easy
to deal with.
When sending out the data to the client we might have to convert, but
that isn't new.
cheers,
Gerd

I have just noticed that we haven't actually written anywhere what's the
oldest version of pixman we support.
Do you know which one it is?
