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 
It is often useful to count things per-frame, and reset
the counter afterwards.

b1e98d106d vulkan: add a frame counter to the profiler 
This is just to match the gl renderer and to learn how
counters work.

816b47d70d gsk: Make profiler counters more useful

by values other than 1.

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.

Go back to a single GskVulkanOpRender that can
handle 0, 1 or 2 sources.

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

Matthias Clasen
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.

a75d995bd4 vulkan: Implement crossfade 
This is the first shader using two textures. It almost works.

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.

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.

b97fb75146 gsk: vulkan: rework image layout/access transitions 
By tracking the last transition we can build the appropriate barriers.
Also use the most appropriate initial layout/access at creation :

for linear image : predefined (we prepare the content ourself through memcpy)
for everything else : undefined (we don't care about the content, will most likely be erase)

4d4a0212fb vulkan: Better glyph cache api 
Move the glyph caching api to something that can support using
multiple textures. We now split the text render ops into multiple
ops for different textures, and make each op render just a substring
of the text node's glyph string.

47cf17c70c vulkan: Add a primitive glyph cache 
This is just a proof of concept - we use a single 1024x1024 surface,
and just give up when we run out of space. The cache is populated
incrementally, and items are never removed.
