The type of u_get_transfer_vtbl of the usage argument in u_transfer.h is
unsigned and not enum pipe_transfer_usage. This patch changes the type
of usage to unsigned to match the prototype in the header file.

Standard library functions in C++ are in the std namespace. When using
C++-style header files for the standard library, some compilers, such as
Sun Studio, provide symbols only for the std namespace and not for the
global namespace.
This patch adds using statements for standard library functions. Another
option could have been to prepend standard library function calls with
'std::'.
This patch fixes several compilation errors with Sun Studio.

For mipmap generation we need all levels in the flushing texture.

This just adds a flag to create the texture without doing any
flushing to it. Flushing occurs in the draw function. This avoids
unnecessary flushes when we end up rebinding a CB/DB/texture due
to the blitter just restoring state.

This checks the color buffer bindings to make sure there is something

If we are going to blit from a depth texture we need to flush
it before we blit from it.

Plus other assorted clarifications.

Before, the set_sampler_views() and restore_sampler_views() functions
used MAX2(old,new) to tell the driver how many samplers or sampler
views to set. This could result in cases such as:
pipe->set_fragment_sampler_views(pipe, 4, views={foo, bar, NULL, NULL})
Many/most gallium drivers would take this as-is and set
ctx->num_sampler_views=4 and ctx->sampler_views={foo, bar, NULL, NULL, ...}.
Later, loops over ctx->num_sampler_views would have to check for null
pointers. Worse, the number of sampler views and number of sampler CSOs
could get out of sync:
ctx->num_samplers = 2
ctx->samplers = {foo, bar, ...}
ctx->num_sampler_views = 4
ctx->sampler_views={Foo, Bar, NULL, NULL, ...}
So loops over the num_samplers could run into null sampler_views pointers
or vice versa.
This fixes a failed assertion in the SVGA driver when running the Mesa
engine demo in AA line mode (and possibly other cases).
It looks like all gallium drivers are careful to unreference views
and null-out sampler CSO pointers for the units beyond what's set
with the pipe::bind_x_sampler_states() and pipe::set_x_sampler_views()
functions.
I'll update the gallium docs to explain this as well.

OpenGL ES1 and OpenGL ES2. It will be used by egl_dri2

Leak was introduced when fixing strict aliasing violation in this code:
the reference counting was preserved, but the destructor call on zero
reference count was not.

See comment for more details.

Exactly one half would be the ideal, but this is a soft limit, and one
more byte over brings us to synchronous behavior.
Flushing when the referred GMR exceeds one third of the aperture gives us
statistically better performance.

Only svga_context_flush should do it, to ensure upload commands are not
submitted to hardware in an inconsistent state.

Certain mingw32 cross compilers (e.g. RedHat's) defaults to use DLL gcc
runtime.
Given the main deliverable from this project are self-contained drivers,
which are loaded by any application, this dependency can cause havoc.

With the previous fixes we can now enabled hw depth copies
Signed-off-by: Dave Airlie <airlied@redhat.com>

If we get a sw accessible buffer like the S8 texture we end up
doing depth tracking on it when there is no need since we won't
ever bind it to the hardware. This leads to a sw fallback in the
transfer destruction which leads to and endless recusion loop
of fail in transfer destroy.

this adds a flag to keep track of whether the depth texture structure
is the flushed texture or not, so we can avoid doing flushes when
we do a hw rendering from one to the other.
it also renames flushed to dirty_db which tracks if the DB copy
has been dirtied by being bound to the hw.

To be consistant with vertex, geometry sampler fields.
|
|
This consolidates the code duplicated between the fragment sampler
and vertex sampler functions. Plus, it'll make adding support for
geometry shader samplers trivial.

To better distinguish from vertex sampler fields.
|

Before we were looping to nr_samplers, which is the number of fragment
samplers, not vertex samplers.

Do not constant-fold a reciprocal if any component of the reciprocated
expression is 0. For example, do not constant-fold `1 / vec4(0, 1, 2, 3)`.
Incorrect, previous behavior
----------------------------
Reciprocals were constant-folded even when some component of the
reciprocated expression was 0. The incorrectly applied arithmetic was:
1 / 0 := 0
For example,
1 / vec4(0, 1, 2, 3) = vec4(0, 1, 1/2, 1/3)

This was my mistake when converting from talloc to ralloc. I was
confused because the other calls in the function are to asprintf_append
and the original code used str as the context rather than NULL.

Previously a register would be marked as available if any component
was written. This caused shaders such as this:
0: TEX TEMP[0].xyz, INPUT[14].xyyy, texture[0], 2D;
1: MUL TEMP[1], UNIFORM[0], TEMP[0].xxxx;
2: MAD TEMP[2], UNIFORM[1], TEMP[0].yyyy, TEMP[1];
3: MAD TEMP[1], UNIFORM[2], TEMP[0].zzzz, TEMP[2];
4: ADD TEMP[0].xyz, TEMP[1].xyzx, UNIFORM[3].xyzx;
5: TEX TEMP[1].w, INPUT[14].xyyy, texture[0], 2D;
6: MOV TEMP[0].w, TEMP[1].wwww;
7: MOV OUTPUT[2], TEMP[0];
8: END
to produce incorrect code such as this:
BEGIN
DCL S[0]
DCL T_TEX0
R[0] = MOV T_TEX0.xyyy
U[0] = TEXLD S[0],R[0]
R[0].xyz = MOV U[0]
R[1] = MUL CONST[0], R[0].xxxx
R[2] = MAD CONST[1], R[0].yyyy, R[1]
R[1] = MAD CONST[2], R[0].zzzz, R[2]
R[0].xyz = ADD R[1].xyzx, CONST[3].xyzx
R[0] = MOV T_TEX0.xyyy
U[0] = TEXLD S[0],R[0]
R[1].w = MOV U[0]
R[0].w = MOV R[1].wwww
oC = MOV R[0]
END
Note that T_TEX0 is copied to R[0], but the xyz components of R[0] are
still expected to hold a calculated value.

glsl-fs-color-matrix. It also fixes Meego bugzilla #13005.
