Currently, we use set_domain() to cause a stall on rendering. But the
set-domain ioctl has the side-effect of changing the kernel's cache
domain underneath the struct_mutex, which may perturb state if there was
no rendering to wait upon and in general is much heavier than the
lockless wait-ioctl. Historically libdrm used set-domain as we did not
have an explicit wait-ioctl (and the patches to teach it to use wait if
available were lost in the mists). Since mesa already depends upon a
kernel support the wait-ioctl, we do not need to supply a fallback.

The reason we were doing this was to ensure that the kernel did the
appropriate cross-ring synchronization and flushing. However, the
kernel only looks at EXEC_OBJECT_WRITE to determine whether or not to
insert a fence. It only cares about the domain for determining whether
or not it needs to clflush the BO before using it for scanout but the
domain automatically gets set to RENDER internally by the kernel if
EXEC_OBJECT_WRITE is set.

Since radv uses compute rings and we can't know when we are setting
up the shaders what ring they are to be used on, we should just use
the default xnack setting. This may be suboptimal in some places,
but if we hit a problem, we likely should try and address this
between llvm and mesa.

It could only handle indices 0/1, otherwise what happened was bad (accessing
array out of bounds, no crash but kind of random). This is enough for the gl
state tracker (primary/secondary color) but not enough for some other state
trackers (d3d9 has no limits on the number of color interpolants).
The complexity with color semantics are all due to the front/back mapping (2
outputs in the vs map to one input in the fs) so this isn't extended to
indices > 1 - d3d9 has no use for back colors, therefore this isn't needed and
still only 2 back colors can be handled correctly.

By design pixel shaders can have up to 3 variants:
* The standard one.
* glDrawPixels variant.
* glBitmap variant.
However "shader_has_one_variant" ignores this fact, and therefore
st_update_fp would select the wrong variant if glDrawPixels or glBitmap
was ever called.
This patch fixes the problem. If the standard variant has been created,
calling glDrawPixels or glBitmap will append the variant to the second
entry of the linked list, so that st_update_fp still selects the right
one if shader_has_one_variant is set.
If the standard variant hasn't been created yet and glDrawPixel/Bitmap
has been called, st_update_fp will will see this and take the slow path
instead. The standard variant will then be added at the front of the
linked list, so that the next time the fast path is taken.
Blender in particular is hit by this bug.

If we try to build a display list with just a glPrimitiveRestartNV()
call, we'd crash because of a null GLvertexformat::PrimitiveRestartNV
pointer. This change fixes that case.
The previous patch fixed the case of calling glPrimitiveRestartNV()
inside a glBegin/End pair.
v2: minor clean-up in save_PrimitiveRestartNV(), per Charmaine.
Reviewed-by: Charmaine Lee <charmainel@vmware.com>
glPrimitiveRestartNV crashes when it is called during the compilation
of a display list.
There are two reasons:
- ctx->Driver.CurrentSavePrimitive is not set to the current primitive
- save_PrimitiveRestartNV() calls _save_Begin() which only sets an
OpenGL error, instead of calling vbo_save_NotifyBegin().
This patch correctly calls vbo_save_NotifyBegin() but it detects
the current primitive mode by looking at the latest saved primitive.

Despite being a member of the etna_screen struct, 'refcnt' is used by

is removed from the table and destroyed.
Fix the logic by initializing the refcnt to 1 when screen created.
This initialization is done in etna_screen_create(), to follow the
same logic as in freedreno and virgl.

Current selection of pixel format does not enforce the request of
stencil or depth buffer if the color depth is not the same as
requested.
For instance, GLUT requests a 32-bit color buffer with an 8-bit
stencil buffer, but because color buffers are only 24-bit, no
priority is given to creating a stencil buffer.
This patch gives more priority to the creation of requested buffers
and less priority to the difference in bit depth.

The Piglit arb_clear_texture-error test creates a texture with only
a 1x1 image at level=1, then tries to clear level 0 (nonexistent)
and level 1 (exists). The test only checks that the former generates
an error but the later doesn't. The test passes, but when we try
to clear the level=1 image we're passing an invalid level to
pipe_context::clear_texture(). level=1, but since there's only one
mipmap level in the texture, it should be zero.
This fixes the code to search the gallium texture resource for the
correct mipmap level. Also, add an assertion to make sure we're not
passing an invalid level to pipe_context::clear_texture().
