This adds support for this to more drivers, in particular for all the "special"
ones useful for debugging.
HW drivers are left alone, some should be able to support it if they want but
they may not be interested at this point.

The new function replaces four old functions: set_fragment/vertex/
geometry/compute_sampler_views().
Note: at this time, it's expected that the 'start' parameter will
always be zero.

Usage with pipe_context:
pipe->flush(pipe, NULL, PIPE_FLUSH_END_OF_FRAME);
Usage with st_context_iface:
st->flush(st, ST_FLUSH_END_OF_FRAME, NULL);
The flag is only a hint for drivers. Radeon will use it for buffer eviction
heuristics in the kernel (e.g. for queries like how many frames have passed
since a buffer was used).
The flag is currently only generated by st/dri on SwapBuffers.

This allows updating only a subrange of buffer bindings.
set_vertex_buffers(pipe, start_slot, count, NULL) unbinds buffers in that
range. Binding NULL resources unbinds buffers too (both buffer and user_buffer
must be NULL).
The meta ops are adapted to only save, change, and restore the single slot
they use. The cso_context can save and restore only one vertex buffer slot.
The clients can query which one it is using cso_get_aux_vertex_buffer_slot.
It's currently set to 0. (the Draw module breaks if it's set to non-zero)
It should decrease the CPU overhead when using a lot of meta ops, but
the drivers must be able to treat each vertex buffer slot as a separate
state (only r600g does so at the moment).
I can imagine this also being useful for optimizing some OpenGL use cases.

"get_transfer + transfer_map" becomes "transfer_map".
"transfer_unmap + transfer_destroy" becomes "transfer_unmap".
transfer_map must create and return the transfer object and transfer_unmap
must destroy it.
transfer_map is successful if the returned buffer pointer is not NULL.
If transfer_map fails, the pointer to the transfer object remains unchanged
(i.e. doesn't have to be NULL).

To support pipe->bind_sampler_states() w/ start_slot.

PIPE_MAX_SAMPLERS, PIPE_MAX_VERTEX_SAMPLERS and PIPE_MAX_GEOMETRY_SAMPLERS
were all defined to the same value (16).
In various places we're creating arrays such as
sampler_views[PIPE_SHADER_TYPES][PIPE_MAX_SAMPLERS] so we were assuming
the same number of max samplers for all shader stages anyway.
Of course, drivers are still free to advertise different numbers of max
samplers for different shaders.

The motivation behind this is to add some self-documentation in the code
about how each CAP can be used.
The idea is:
- enum pipe_cap is only valid in get_param
- enum pipe_capf is only valid in get_paramf
Which CAPs are floating-point have been determined based on how everybody
except svga implemented the functions. svga have been modified to match all
the other drivers.
Besides that, the floating-point CAPs are now prefixed with PIPE_CAPF_.

It is sometimes useful to examine the first frame or and early frame of a
quickly executing and non-repeating application, this chain introduces a new
environment variable that is checked when creating contexts. If
GALLIUM_RBUG_START_BLOCKED is set, then each context that is created is started
in a blocked state. This allows time to connect rbug before anything is
rendered in the context.

This moves the gallium interface for clears from using a pointer to 4 floats to a pointer to a union of float/unsigned/int values.
Notes:
1. the value is opaque.
2. only when the value is used should it be interpretered according to
the surface format it is going to be used with.
3. float clears on integer buffers and vice-versa are undefined.
v2: fixed up vega and graw, dropped hunks that shouldn't have been in
patch.

The drivers have been changed so that they behave as if all of the flags
were set. This is already implicit in most hardware drivers and required
for multiple contexts.
Some state trackers were also abusing the PIPE_FLUSH_RENDER_CACHE flag
to decide whether flush_frontbuffer should be called.
New flag ST_FLUSH_FRONT has been added to st_api.h as a replacement.
|
| | |
|
| |
|
|

So that they don't have the driver-specific param and return type.

Only st/xorg used it and even incorrectly with regards to pipelined transfers.

|
|
|

This is a follow-up to the ARB_sync patch for st/mesa and completes
the ARB_sync implementation.
|
| | |
|

Also implement the redefine_user_buffer hook in the drivers.

resources have a array_size parameter now.
get_tex_surface and tex_surface_destroy have been renamed to create_surface
and surface_destroy and moved to context, similar to sampler views (and
create_surface now uses a template just like create_sampler_view). Surfaces
now really should only be used for rendering. In particular they shouldn't be
used as some kind of 2d abstraction for sharing a texture. offset/layout fields
don't make sense any longer and have been removed, width/height should go too.
surfaces and sampler views now specify a layer range (for texture resources),
layer is either array slice, depth slice or cube face.
pipe_subresource is gone array slices (or cube faces) are now treated the same
as depth slices in transfers etc. (that is, they use the z coord of the
respective functions).

This is much more consistent with the other fields used there
(first/last level, first/last layer).
Actually thinking about removing the ugly union/structs again and
rename first/last_layer to something even more generic which could also
be used for buffers (like first/last_member) without inducing headaches.

gallium: separate depth0 and array_size in the resource itself.
These fields are still mutually exclusive (since no 3d array textures exist)
but it ultimately seemed to error-prone to adapt all code accept the new
meaning of depth0 (drivers stick that into hardware regs, calculate mipmap
sizes etc.). And it isn't really cleaner anyway.
So, array textures will have depth0 of 1, but instead use array_size,
3D textures will continue to use depth0 (and have array_size of 1). Cube
maps also will use array_size to indicate their 6 faces, but since all drivers
should just be fine by inferring this themselves from the fact it's a cube map
as they always used to nothing should break.

gallium: adapt code to interface changes
There are still usages of pipe_surface where pipe_resource should be used,
which should eventually be fixed.

gallium: more interface changes
In particular to enable usage of buffers in views, and ability to use a
different pipe_format in pipe_surface.
Get rid of layout and offset parameter in pipe_surface - the former was
not used in any (public) code anyway, and the latter should either be computed
on-demand or driver can use subclass of pipe_surface.
Also make create_surface() use a template to be more consistent with
other functions.

mesa/st: adapt to interface changes
still need to fix pipe_surface sharing
(as that is now per-context).
Also broken is depth0 handling - half the code assumes
this is also used for array textures (and hence by extension
of that cube maps would have depth 6), half the code does not...

gallium: more interface fail, docs
this also changes flush_frontbuffer to use a pipe_resource instead of
a pipe_surface - pipe_surface is not meant to be (or at least no longer)
an abstraction for standalone 2d images which get passed around.
(This has also implications for the non-rendering state-trackers.)

gallium: interface changes for array textures and related cleanups
This patch introduces array textures to gallium (note they are not immediately
usable without the associated changes to the shader side).
Also, this abandons pipe_subresource in favor of using level and layer
parameters since the distinction between several faces (which was part of
pipe_subresource for cube textures) and several z slices (which were not part
of pipe_subresource but instead part of pipe_box where appropriate for 3d
textures) is gone at the resource level.
Textures, be it array, cube, or 3d, now use a "unified" set of parameters,
there is no distinction between array members, cube faces, or 3d zslices.
This is unlike d3d10, whose subresource index includes layer information for
array textures, but which considers all z slices of a 3d texture to be part
of the same subresource.
In contrast to d3d10, OpenGL though reuses old 2d and 3d function entry points
for 1d and 2d array textures, respectively, which also implies that for instance
it is possible to specify all layers of a 2d array texture at once (note that
this is not possible for cube maps, which use the 2d entry points, although
it is possible for cube map arrays, which aren't supported yet in gallium).
This should possibly make drivers a bit simpler, and also get rid of mutually
exclusive parameters in some functions (as z and face were exclusive), one
potential downside would be that 3d array textures could not easily be supported
without reverting this, but those are nowhere to be seen.
Also along with adjusting to new parameters, rename get_tex_surface /
tex_surface_destroy to create_surface / surface_destroy and move them from
screen to context, which reflects much better what those do (they are analogous
to create_sampler_view / sampler_view_destroy).
PIPE_CAP_ARRAY_TEXTURES is used to indicate if a driver supports all of this
functionality (that is, both sampling from array texture as well as use a range
of layers as a render target, with selecting the layer from the geometry shader).

Use scons target and dependency system instead of ad-hoc options.
Now is simply a matter of naming what to build. For example:
scons libgl-xlib
scons libgl-gdi
scons graw-progs
scons llvmpipe
and so on. And there is also the possibility of scepcified subdirs, e.g.
scons src/gallium/drivers
If nothing is specified then everything will be build.
There might be some rough corners over the next days. Please bare with me.

Changes in v3:
- Also change trace, which I forgot about
Changes in v2:
- No longer adds tessellation shaders
Currently each shader cap has FS and VS versions.
However, we want a version of them for geometry, tessellation control,
and tessellation evaluation shaders, and want to be able to easily
query a given cap type for a given shader stage.
Since having 5 duplicates of each shader cap is unmanageable, add
a new get_shader_param function that takes both a shader cap from a
new enum and a shader stage.
Drivers with non-unified shaders will first switch on the shader
and, within each case, switch on the cap.
Drivers with unified shaders instead first check whether the shader
is supported, and then switch on the cap.
MAX_CONST_BUFFERS is now per-stage.
The geometry shader cap is removed in favor of checking whether the
limit of geometry shader instructions is greater than 0, which is also
used for tessellation shaders.
WARNING: all drivers changed and compiled but only nvfx tested

That is, remove pipe_context::draw_arrays, pipe_context::draw_elements,
pipe_context::draw_arrays_instanced,
pipe_context::draw_elements_instanced,
pipe_context::draw_range_elements.

Some drivers define a generic function that is called by all drawing
functions. To implement draw_vbo for such drivers, either draw_vbo
calls the generic function or the prototype of the generic function is
changed to match draw_vbo.
Other drivers have no such generic function. draw_vbo is implemented by
calling either draw_arrays and draw_elements.
For most drivers, set_index_buffer does not mark the state dirty for
tracking. Instead, the index buffer state is emitted whenever draw_vbo
is called, just like the case with draw_elements. It surely can be
improved.

The new default implementation of pipe_condvar makes it
unnecessary.
