Always test for PIPE_TRANSFER_READ/WRITE using the bit-wise and operator, and
add a pipe_transfer_buffer_flags() helper for getting the buffer usage flags
corresponding to them.

No longer used. S3TC support is queried via
pipe_screen::is_format_supported.

libdrm_nouveau is linked with the winsys, there's no good reason to do all
this through yet another layer.

|
Also implement context member functions to optimize away those
flushes whenever possible.

The format field encodes compressed vs. uncompressed already. We can easily
check if a texture is compressed with pf_is_compressed(texture->format).
|
|
Only allows clearing currently bound buffers, but colour and depth/stencil in
a single call.

I should have gotten most uses and implementation
correctly fixed, but things might break.
Feel free to blame me.

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().

The template makefile that most libraries in
gallium included was based on dri and had a bunch
unrelevant junk in it.
Update it and improve the depending makefiles.

The debug functions depend on several util function for os abstractions, and
these depend on debug functions, so a seperate module is not possible.

If do_flipp is true, it would first do the proper copy, height would
wrap around to unsigned maximum, and then it attempts to do another
copy.
Return after doing the proper copy.

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.
|
|
|
|
move it to pipe/internal/p_winsys_screen.h and start converting
the state trackers to the screen usage
|
|
allows the driver to overwrite buffer allocation, first step on the way
to making winsys interface internal to the drivers. state trackers and
the code above it will go through the screen
|
|
reuse the size of the actual buffer

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 make the type unsigned instead of signed, since negative
values do not make sense.

Also changes nvgl_primitive() to return zero, i.e. error, on unknown
primitive.

Must copy token stream on shader create, client is allowed to free
their copy after creating the state object.
