Use make_temp_float_image instead of _make_temp_chan_image.
The latter converts the texture to 8 bits/component, losing 2 bits.
|
|
Radeon GPUs can do this. R600 can even do render-to-texture.
Packing and extracting aren't implemented, but we shouldn't hit them (I think).
Tested with swrast, softpipe, and r300g.

Radeon GPUs do support GL_RGB10_A2.

The code's cleaner and a step toward supporting float-valued texture sampling.
Some optimizations for common cases can be added and re-enabled...

Core Mesa provides a neutral tnl module that verifies the currently
module before installing the tnl function pointers in a lazy fashion.
It also records which tnl functions have been swapped out, and only
restores these when tnl modules themselves are swapped.
Fallback strategies:
Drivers set a bitmask of dangerous stage changes. When such a state
change occurs, the driver should restore the neutral tnl module via
_mesa_restore_exec_vtxfmt(). The neutral tnl module will call
_mesa_update_state(), followed by ctx->Driver.ValidateTnlModule() if the
validation bitmask matches the new state bitmask. The driver should
call _tnl_wakeup_exec() if it can no longer handle the current state,
which will revert to the default tnl module. In this case, previous
vertices should be replayed as required (depending on the current
primitive) after the new tnl module is installed.
If the driver uses chooser functions for any part of the tnl module,
these should generally be reinstalled as part of the fallback to the
neutral tnl module. For example, if the lighting state changes, a
driver might fall back to the neutral tnl module, verify that the
current lighting state can be handled, and use the chooser function to
pick the most efficient implementation of the current lighting state.
It is up to the drivers to detect and handle fallback cases caused by
tnl function calls themselves (such as glTexCoord4f* if the current tnl
module can't handle projected textures, for example).

FLOAT_TO_CHAN() macro removed.

Clean-up of color conversion macros.
New mmath.h macros (IROUND, IFLOOR, ICEIL, FRAC) used in various places.

driver (enable with FX_ALLOW_VTXFMT=t).

math: Provides basic matrix and vector functionality that
might be useful to multiple software t&l
implementations, and is used by core mesa to
manage the Model, Project, etc matrices.
tnl: The real transform & lighting code from core mesa,
including everything from glVertex3f through vertex
buffer handling, transformation, clipping, lighting
and handoff to a driver for rasterization.
The interfaces of these can be further tightened up, but the basic
splitting up of state and code move is done.

Some header file re-org:
Move matrix, vertex buffer structs to types.h to fix #include mess.
Remove typedef, extern declarations from config.h
|
|
Lot's of clean-up in macros.h and mmath.h
