50bea37320 Reshuffle things a little bit 
Instead of having a function with lots of arguments in
GskVulkanRender that we call from GskVulkanRenderPass which
then just calls back into GskVulkanRenderPass, just create
the new render pass object locally, and an api to add it
to the list that GskVulkanRender keeps. This makes it
a lot easier to preserve all the relevant parameters from
the parent render pass.

983e0b7956 Small simplification 
Just keep the viewport as a graphene_rect_t, we don't need
to use the Vulkan type here.

4c29102753 vulkan: Add a counter for intermediate textures 
Count how many pixels of intermediate textures we create.
If we can count it, we can optimize it.

836e18cc96 Support repeat nodes in vulkan 
We can use the texture pipeline for this, with a repeating sampler.

31d8fe3a6a vulkan: Add a repeating sampler 
None of the render ops use it, yet.

This is in preparation of allowing multiple samplers.

5577fde990 vulkan: Rename blend pipeline to texture 
This is what it does, and the name blend is easily
confused with blend-mode.

538e7c7982 vulkan: Allow to control scaling in the blend pipeline 
Pass in a second rect that defines the size of the texture.
Update the sole caller to pass in the same rect, for unchanged
behavior.

9e2e6c1115 gsk: Fix a typo 
Repeating linear gradient nodes share most of the implementation
with linear gradient nodes, but they shouldn't share the class name.

e45ab76664 gsk: remove gsk_blend_node_get_blend_mode from public api 
We don't have any other such getters in the public api at
this point, so leave this one out as well.

535529ca98 vulkan: Measure gpu time 
Since this value is only meaningful if we wait for the rendering
to end, we only keep this timer if GSK_RENDERING_MODE=sync is
enabled.

72d043d51f gsk: Change the profiler setup 
Move away from the idea of intra-frame sampling, since we only
push samples once per frame, anyway. Instead, make the profiler
keep a rolling average of the last n frames.
 2017-09-28 10:26:01 -04:00
Matthias Clasen
767966933d gsk: Redo the sampling in the profiler 
Reset the min/max/average counters before calculating,
and only print the values if we have samples. In addition,
print the number of samples.

4d8e7d71ca gsk: Add a profile counter for vulkan render passes 
This is interesting now that we have multiple render passes.

d61a715909 vulkan: Implement multiple render passes 
Whenever we need a node as a texture, we now start a new render
pass that renders the node into a new intermediate texture, and
set up a semaphore to make the current render pass wait for it.

As part of this reorganization, much of the setup and drawing
code moved from gskvulkanrender.c to gskvulkanrenderpass.c.

85e4e0672a Add semaphores to the command buffer submit api 
Allow to pass in semaphores to wait for before executing
and to signal after executing the command buffer. This
just exposes the capabilities of the underlying Vulkan
api. Update all callers to pass no semaphores, for now.

We will use this in the future.

ff188f6bf0 Add an api to create intermediate textures 
The new function creates a vulkan image that is suitable for
use as a framebuffer to render to and as a texture to read from.

485470511f vulkan: Update the outset-shadow fragment shaders 
These were missing the blur-radius parameter that is written
by the vertex shader, causing Vulkan validation to complain.

145e4fde92 gsk: Fix Vulkan validation errors for image upload 
I've finally figured out the right combination of src and dest
stage and access flags to make all validation warnings go away.
This commit only fixes the direct upload code.

ae2c645a2a gsk: report fallback pixels as a profile counter 
This makes the value show up in the inspector without
any extra work. We report the number per-frame, since
that makes the most sense.

cfbd6b4b99 gsk: Add a way to reset profiler counters

b1e98d106d vulkan: add a frame counter to the profiler

b5ac277654 Plug a memory leak 
A function with ensure in the name would better check if the
thing it is supposed to ensure already exists.

3c98b90fc6 vulkan: Implement nonseparable blendmodes 
This is a directly-from-the-spec, unoptimized implementation.

d61f6ff393 vulkan: Implement blend modes 
This is another example for a 2-texture shader.
So far, only separable blend modes are implemented.
The implementation is not optimized, with an
if-else cascade in the shader.

b192120f39 vulkan: fix a clip handling problem 
We were looking at uninitialized memory here, instead
of the type of the source clip, as we should.

This showed up as mispositioned clip in the first frame
of a crossfade stack transition, and also as overdraw in
sliding stack transitions.

8ad0539cf7 vulkan: Drop GskVulkanPipelineLayout 
We already move the descriptor set layout out of it,
so we can just as well keep the pipeline layouts in
the render object as well, and get rid of this extra
object. Update all callers.
 2017-09-22 22:16:09 -04:00
Matthias Clasen
9b0ee4ac99 Allow different pipeline layouts 
These are differentiated by the number of textures; currently
we have shaders with 0 and 1 textures.

5ff6481310 Add a getter to the pipeline layout directly from the pipeline 
This is a step towards allowing multiple pipeline layouts.

4c7a51f88a vulkan: Move descriptor set layout to the render object 
We want to maintain a single descriptor set layout while introducing
multiple pipeline layouts, so split this off.

commit.

64322a2c41 vulkan: Add an api to update multiple image regions 
Instead of doing multiple copy commands with a tiny buffer
for each glyph, we can just batch them all together. This
also avoids the issue of creating multiple barriers for the
same image.
