When we set these up initially, no subsystems have allocated any
privates yet, so the storage address will be null, and memset(NULL, ...)
is undefined.
Separate each statement of the form "assert(a && b);" into "assert(a);"
and "assert(b);" for more precise diagnostics, except for this clever
use in drmmode_display.c where it was used to pass a hint to developers:
assert(num_infos <= 32 && "update return type");
Roundhouse kick replacing the various (sizeof(foo)/sizeof(foo[0])) with
the ARRAY_SIZE macro from dix.h when possible. A semantic patch for
coccinelle has been used first. Additionally, a few macros have been
inlined as they had only one or two users.

The modesetting driver corrupts memory when used after a server regeneration
because not enough memory is allocated for its pixmap privates. This happens
because its call to dixRegisterScreenSpecificPrivateKey() does nothing because
key->initialized is still TRUE from the first server generation. However, the
key is not in the screen's linked list of screen-specific privates because
that's freed and reallocated during the server generation loop in dix_main().
Fix this by clearing key->initialized before CloseScreen and add a call to
dixFreeScreenSpecificPrivates() for GPU screens.
v2: Just set key->initialized to FALSE and move dixFreeScreenSpecificPrivates()
calls to after CloseScreen.
v3: Move dixFreeScreenSpecificPrivates() calls back to just before CloseScreen.

When allocating new global privates, make sure the gpu

This only affects GPU screens that enumerate before the non-GPU
screens, which generally requires that the related device be present
when the system boots so that it can get an earlier DRM filename.

This patch introduces gpu screens into screenInfo. It adds interfaces
for adding and removing gpu screens, along with adding private fixup,
block handler support, and scratch pixmap init.
GPU screens have a myNum that is offset by GPU_SCREEN_OFFSET (256),
this is used for logging etc.
RemoveGPUScreen isn't used until "xfree86: add platform bus hotplug support".
v2: no glyph pictures for GPU screens for now.
v3: introduce MAXGPUSCREENS, fix return value check
v4: fixup myNum when renumbering screens (ajax)
v5: drop cursor privates for now.

Screen-specific privates areas are only allocated for objects related
to the target screen; objects allocated for other screens will not
have the private space reserved. This saves memory in these objects
while also allowing hot-plug screens to have additional private
allocation space beyond what the core screens are using.
Drivers are encouraged to switch to this mechanism as it will reduce
memory usage in multi-GPU environments, but it is only required for
drivers which will be loaded after the server starts, like
modesetting.
Objects providing screen-specific privates *must* be managed by the
screen-specific private API when allocating or initializing privates
so that the per-screen area can be initialized properly.
The objects which support screen-specific privates are:
Windows
Pixmaps
GCs
Pictures
Extending this list to include Colormaps would be possible, but
require slightly more work as the default colormap is created before
all colormap privates are allocated during server startup, and hence
gets a bunch of special treatment.
Of particular note, glyphs are *not* capable of supporting
screen-specific privates as they are global objects, not allocated on
a screen-specific basis, and so each driver must be able to see their
privates within the glyph.

The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.
The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.
The comparison was done with this script:

for dir in $dir1 $dir2; do

Keys need to persist through server reset so that the private system
can be cleaned up in dixResetPrivates. In particular, this means that

suitable object lifetime by having the privates code free the key in

It can be reproduced when the server is regenerated and for some
reason the private keys are reassigned in a different order: a
manually allocated private may get an index formerly used by a
preallocated private. In that case it will first be manually freed and
then again by dixFreePrivates, as items[i].size was never zeroed
out. Do it in dixResetPrivates.

Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.
Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.
Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:
