Due to implemtation details on the host side, switching to a multihead
fullscreen mode means multiple mode changes along the way. However,
because rrSetScreenConfig returns before the mode change completes,
we can enter a race, where a subsequent SetDisplayTopology overrides
the current pending one, leading to a mode switch where the resolution
and topology are no longer consistent.
So, we fix this by ignoring any attempts to set the pending topology if
one is already pending.
The X server prunes modes above the initial mode and
the number of default modes varies with distro and
server version. As it's easy to do, let's add a bunch
of useful versions in the driver so that users don't
have to mess with their config files as often.
We have a lot of stale code to 'accelerate' certain operations
through XAA. However, in practice, this acceleration is
completely unhelpful because whenever we encounter an
unaccelerated action, we have to sync and flush the fifo
which kills any performance gain.
As such, the virtual hardware doesn't even advertise these
acceleration capabilities anymore, so the code is completely
unusued.
In addition, XAA is on the way out, so there's no point
leaving in dead code which will have to go in the fairly
near future.
The one operation we can meaningfully accelerate is a
front-only fill and when we get around to implementing
that, we'll use EXA instead.
This change removes the limitation on resizing larger than the
initial size and removes the need for pitch-locking bu resizing
the screen pixmap. Now the only limit on the screen size is
the maximum width/height reported by the virtual hardware which
is configured on the host side.
in xorg.conf. This static configuration will always be used and
any attempts to update it will be ignored.
Note that all xinerama aware apps that I have seen will not
sanity check the xinerama extents against the screen size, so
if the screen doesn't properly enclose the xinerama extents,
expect your apps to punish you accordingly.
With this change, the VMWARE_CTRL extension is updated so that it can
receive topology updates at runtime. I will add some sample client code
separately.
I also intend to add support for a static initial topology defined in
xorg.conf but I haven't got around to it yet due to hating to write
string parsing code.
- Verify and update package version numbers as needed
- Implement versioning scheme
- Change bug address to point to bugzilla bug entry form
- Disable loadable i18n in libX11 by default (use --enable-loadable-i18n to
reenable it)
- Fix makedepend to use pkgconfig and pass distcheck
- Update build script to build macros first
- Update modular Xorg version
