Similar to u_blitter, u_upload_mgr is now a client of the pipe context. Its
creation needs to be delayed until the context has been (almost) initialized.

This adds support to gallium for a TG4 instruction,
and two CAPs. The first CAP is required for GL_ARB_texture_gather.
The second CAP is required to expose GL_ARB_gpu_shader5.
However so far we haven't found any hardware that natively
exposes the textureGatherOffsets feature from GL, so just
lower it for now. If hardware appears for this we can add
another CAP to allow TG4 to take 4 offsets.
v2: add component selection src and a cap to say
hw can do it. (st can use to help control
GL_ARB_gpu_shader5/GLSL 4.00). Add docs.
v3: rename to SM5, add docs.

Use tex->bo_format instead of zs->format in ilo_blitter_rectlist_clear_zs()
because the latter may be combined depth/stencil format. hiz_can_clear_zs()
is no-op for GEN7+, but move the GEN check so that the assertions are tested.
Finally, call the fast depth clear function from ilo_clear().

It is needed for 3DSTATE_CLEAR_PARAMS, and can also be used to track what
value the slice has been cleared to.

3DSTATE_STENCIL_BUFFER inherits some states from 3DSTATE_DEPTH_BUFFER. We
need to emit both even the surface is stencil only.

We need to disable HiZ for non-8x4 aligned levels, except for level 0, layer
0. For the very first layer we can adjust Width and Height fields of
3DSTATE_DEPTH_BUFFER to make it aligned.
Specifically, add ILO_TEXTURE_HIZ and set the flag only for properly aligned
levels. ilo_texture_can_enable_hiz() is updated to check for the flag.
In tex_layout_validate(), align the depth bo to 8x4 so that we can adjust
Width/Height of 3DSTATE_DEPTH_BUFFER without introducing out-of-bound access.
Finally in rectlist blitter, add the ability to adjust 3DSTATE_DEPTH_BUFFER.
|
|
|
|
|
| |
Add ilo_texture_can_enable_hiz and replace all checks for tex->hiz.bo by calls
to ilo_texture_can_enable_hiz().
|
|
|
|
|
|
|
|
|
| |
Add tex_layout_init_hiz() before tex_layout_init_format() to decide whether
HiZ should be enabled.
On GEN6, because of layer offsetting, HiZ is enabled only when the texture is
non-mipmapped and non-array. PIPE_USAGE_STAGING is also taken as a hint to
disable HiZ.
|
|
|
|
|
|
|

Rename the workaround, as it is for 3DSTATE_PS instead of 3DSTATE_WM, and emit
it on Haswell too.
This does not fix any app, but an assertion failure.

On GEN6, HiZ and Separate Stencil Buffer must be enabled at the same time.
|
|
|
|

Dereference the HiZ bo when the texture is destroyed.
|
|
|
|
|
| |
Call ilo_texture_get_slice() for the last slice so that we can get rid of the
duplicated assert().
|
|
|
|
|
|

The support is still early. Fast depth buffer clear is not enabled yet.
HiZ can be forced off with ILO_DEBUG=nohiz.
|
|
|
|
|
|
| |
When the depth buffer is to be read, perform a Depth Buffer Resolve if it has
been rendered. When the depth buffer is to be rendered, perform a HiZ Buffer
Resolve when the depth buffer is modified externally.

The flags are used to mark who (CPU, BLT, or RENDER) has accessed the resource

ilo_texture_get_slice().

Add blitter functions to perform Depth Buffer Clear, Depth Buffer Resolve, and
Hierarchical Depth Buffer Resolve. Those functions set ilo_blitter up and

Add tex_create_hiz() to create HiZ bo. It is not really called yet.

Move separate stencil allocation code to tex_create_separate_stencil to keep
tex_create sane.

Allow HiZ op to be specified in 3DSTATE_WM. Pass depth format directly in
gen7_emit_3DSTATE_SF. Use tex->hiz.bo to determine if HiZ exists. Fix
3DSTATE_SF for the case when there is no ilo_rasterizer_state. Fix
3DSTATE_PS for the case when there is no ilo_shader_state.

Even though the Ivy Bridge PRM lists some restrictions that require layer
offsetting as the Sandy Bridge PRM does, it seems they are actually lifted.

GEN6 has several requirements regarding the LOD/Depth/Width/Height of the
render targets and the depth buffer. We used to offset to the layers in
question unconditionally to meet the requirements. With this commit,
offseting is done only when the requirements are not met.

All bound layers (from first_layer to last_layer) should be cleared.
This uses a vertex shader which outputs gl_Layer = gl_InstanceID, so each
instance goes to a different layer. By rendering a quad and setting
the instance count to the number of layers, it will trivially clear all
layers.
This requires AMD_vertex_shader_layer (or PIPE_CAP_TGSI_VS_LAYER), which only
radeonsi supports at the moment. r600 could do this too. Standard DX11
hardware will have to use a geometry shader though, which has higher overhead.

Ever since introducing separate sampler and sampler view max this was really
missing.
Every driver but llvmpipe reports the same number as number of samplers for
now, so nothing should break.
