The only difference between nv30 and nv40 is that nv30 allowed swizzling
for more texture types.
This patch preserves the existing behavior, using conditional code.
Note however that this does not make sense, since all texture types can
be swizzled on nv40 and probably on nv30 too.
However, the handling of swizzled surfaces in the current 2D code is
partially broken, so it's best not to touch this.
A whole rewrite of the 2D code will be submitted, which will solve this
problem.

This patch unifies nv[34]0_screen.h, nv[34]0_context.h and
nv[34]0_state.h
The unified files are put in a new "nvfx" directory.
nv30_context.h and nv40_context.h still exist to hold the function
prototypes and include nvfx_context.h
nv[34]0_screen.h and nv[34]0_state.h are deleted, replaced by the
unified versions.
nv40 includes some extra fields for swtnl and user clip planes
support.
These fields will be unused on nv30 until that functionality gets
added to it too (by unification with nv40).

gallium: remove p_screen::surface_buffer_create
This isn't very useful without texture_blanket(), which has also been
removed.
Note that this function hasn't been removed from the old pipe_winsys
(u_simple_screen) still used internally by some drivers (eg softpipe).

gallium: remove texture blanket call
No longer needed, except for nouveau and egl/xll/native_ximage.c.
Fix for nouveau is to keep the call, but move it to an internal
function within nouveau.
Fix for that egl/x11 relies on gallium-sw-api branch or its successor.

I just coded a patch that does this and seems to work fine. It must be
fixed since it breaks OpenGL (or the state tracker can be changed, but
it seems better to do it in the driver).
The patch also fixes NV20 and NV30 in the same way. They compile but
are untested.
I would guess that using the 3D engine is faster for the larger
levels, but the 2D engine is faster for the smaller ones (and lacks
this issue).

Previously they depended on format blocks, but after removing those
they started depending on format encoding.
|
|
Thanks to Bob Gleitsmann for the patch.
I'll clean this up in a better way later if noone else beats me to it.

The core reference counting code is centralized in p_refcnt.h.
This has some consequences related to struct pipe_buffer:
* The screen member of struct pipe_buffer must be initialized, or
pipe_buffer_reference() will crash trying to destroy a buffer with reference
count 0. u_simple_screen takes care of this, but I may have missed some of
the drivers not using it.
* Except for rare exceptions deep in winsys code, buffers must always be
allocated via pipe_buffer_create() or via screen->*buffer_create() rather
than via winsys->*buffer_create().

Don't look at nouveau_winsys_pipe.h... I promise it's temporary!
|

this change disassociates, at least from the driver perspective,
the surface from buffer. surfaces are technically now views on the
textures so make it so by hiding the buffer in the internals of
textures.

This commit is mostly just a cosmetic change that cleans-up the interfaces,
replacing pipe_winsys::surface_* calls by
/**
* Allocate storage for a display target surface.
*
* Often surfaces which are meant to be blitted to the front screen (i.e.,
* display targets) must be allocated with special characteristics, memory
* pools, or obtained directly from the windowing system.
*
* This callback is invoked by the pipe_screenwhen creating a texture marked
* with the PIPE_TEXTURE_USAGE_DISPLAY_TARGET flag to get the underlying
* buffer storage.
*/
struct pipe_buffer *(*surface_buffer_create)(struct pipe_winsys *ws,
unsigned width, unsigned height,
enum pipe_format format,
unsigned usage,
unsigned *stride);
Most drivers were updated but not all were tested. Use the softpipe pipe
driver and the xlib winsys changes as a reference when fixing other drivers.

Also flag shadows as dynamic since they're for CPU access as well.

Limit of SIFM on nv40 is 1024x1024, not sure about others.

probably the last match-gallium-upstream merge for a bit, some cleanup+nv50

Untested on NV3x/NV5x. Quite possibly broken.

That was... fun..
