This pulls the top level createNewScreen entry point out of the drivers
and rewrites __driUtilCreateNewScreen in dri_util.c to be the new entry point.
The change moves more logic into the common/ layer and changes the
createNewScreen entry point to only be defined in one place.
|
|
The screenConfigs field of __DRIscreen points back to the containing
__GLXscreenConfigs struct. This is a serious abstraction violation; it
assumes that the loader is libGL and that there *is* a __GLXscreenConfigs
type in the loader.
Using the containerOf macro, we can get from the __DRIscreen pointer to
the containing __GLXscreenConfigs struct, at a place in the stack
where the above is a valid assumption. Besides, the __DRI* structs shouldn't
hold state other than the private pointer.
|
|
Many DRI entry points took a __DRInativeDisplay pointer and a screen
index as arguments. The only use for the native display pointer was to
pass it back to the loader when looking up the __DRIscreen for the given
screen index.
Instead, let's just pass in the __DRIscreen pointer directly, which
let's drop the __DRInativeDisplay type and the getScreen function.
The assumption is now that the loader will be able to retrieve context
from the __DRIscreen pointer when necessary.

Simplification in colortab.c too.
|
|
The clamping for these values depends on whether we're drawing AA or non-AA
points, lines. Defer clamping until drawing time. Drivers could compute and
keep clamped AA and clamped non-AA values if desired.
|
|
Instead of separate fog/specular/texcoord/varying code, just treat all of
them as generic attributes. Simplifies the point/line/triangle functions.

Use _mesa_reference_framebuffer() and _mesa_unreference_framebuffer() functions
to be sure reference counting is done correctly. Additional assertions are
done too. Note _mesa_dereference_framebuffer() renamed to "unreference" as
that's more accurate.

Mostly:
- update #includes
- update STATE_* token code

Implement GLX_SGI_make_current_read for tdfx. Remove annoying debug
printf in tdfxSwapBuffers. Updated a comment in drirenderbuffer.h to
note that the tdfx driver uses a flag that was previously only used by
s3v.
This code was tested with glxgears, wincopy, and manywin.

Based on the old code that implemented GL_HP_occlusion_test, implement
GL_ARB_occlusion_query. This code passes progs/demo/arbocclude.
|
|
Via depth_test_pixels (swrast/s_depth.c), tdfxDDWriteDepthPixels can
be called with mask == NULL. Test for this condition in the places
where mask might be dereference. This matches the behavior of several
other functions in this file with a 'const GLubyte mask[]' parameter.

In 16-bit color modes the 3D driver was erroneously creating fbconfigs
with 16-bits of accumulation alpha. Since the 2D driver always
generates modes with zero bits of alpha, the lists of fbconfigs did
not match and warnings were generated by libGL.

The coordinates need to be computed after we've got the hw lock.
Code updated to:
1. Ignore all/x/y/width/height/ params passed to Clear func.
2. Pass 0,0,0,0,0 to _swrast_Clear() until they're totally removed.

This is already done by the preceeding call to _mesa_init_driver_functions()

a lot of casting elsewhere.

driver.

Some hardware lays out 3D mipmaps in a manner that can't be expressed
with a simple image stride.
The ImageOffsets array is allocated and initialized to typical defaults
in the _mesa_init_teximage_fields() function. If needed, a driver will
then have to replace these offsets.
TexStore and TexelFetch routines updated to use offsets array.

Pass the MESA_FORMAT_* token to the _mesa_compressed_row_stride(),
_mesa_compressed_texture_size() and _mesa_compressed_image_address()
functions since we want to use the driver-chosen format, not the user's
internalFormat hint.

Add additional checks for the *DRIRec info structure passed in from the
device driver. This ensures that things fallback to indirect rendering if
the DDX driver has had modifications (i.e. removal of the drmAddress field).

_glapi_add_entrypoint has been replaced by a new routine called
_glapi_add_dispatch. This new routine dynamically assignes dispatch offsets
to functions added. This allows IHVs to add support for extension functions
that do not have assigned dispatch offsets.
It also means that a driver has no idea what offset will be assigned to a
function. The vast majority of the changes in this commit account for that.
An additional table, driDispatchRemapTable, is added. Functions not in the
Linux OpenGL ABI (i.e., anything not in GL 1.2 + ARB_multitexture) has a
fixed offset in this new table. The entry in this table specifies the
offset in of the function in the real dispatch table.
The internal interface was also bumped from version 20050725 to 20050727.
This has been tested with various programs in progs/demos on:
radeon (Radeon Mobility M6)
r128 (Rage 128 Pro)
mga (G400)

that are currently obtained via glXGetProcAddress and all of the XF86DRI
functions are replaced with a funciton table. This table will be passed to
__driCreateNewScreen.
One of the functions in the table is getProcAddress. This allows some
loaders to expose functionality not in all loaders. This will be immediatly
used for glxEnableExtension (formerly known to drivers as
__glXScrEnableExtension). libGL (and in the future libglx) expose this
function so that drivers can enable GLX extensions. libEGL should exposed
eglEnableExtension to enable EGL extensions. The same function cannot be
used for both because the extensions have different names and (possibly)
different semantics. Drivers can optionally use one, both, or neither.
The key parts are in the __DRIinterfaceMethodsRec structure in
dri_interface.h. A pointer to one of these structures is passed into
__driCreateNewScreen. Because of this, the version of the API is bumped to
20050725. Since the previous version(s) were never in a release, their
existance is erased.
I was actually a little surprised by how much code this cuts from the
drivers. A lot of glXGetProcAddress calls disappear, and a lot of
version checks go with them. Nice.
The one thing I'm not sure of is removing __glXInitialize. For some
reason that function was in the glXGetProcAddress table, but *nothing*
in the Mesa tree used it. Did something with DRI conf. use this
function? It seems odd...
