Shahbaz Youssefi e54d0f90 2019-06-30T03:26:18 Vulkan: Debug overlay A debug overlay system for the Vulkan backend designed with efficiency and runtime configurability in mind. Overlay widgets are of two fundamental types: - Text widgets: A single line of text with small, medium or large font. - Graph widgets: A bar graph of data. Built on these, various overlay widget types are defined that gather statistics. Five such types are defined with one widget per type as example: - Count: A widget that counts something. VulkanValidationMessageCount is an overlay widget of this type that shows the number of validation messages received from the validation layers. - Text: A generic text. VulkanLastValidationMessage is an overlay widget of this type that shows the last validation message. - PerSecond: A value that gets reset every second automatically. FPS is an overlay widget of this type that simply gets incremented on every swap(). - RunningGraph: A graph of last N values. VulkanCommandGraphSize is an overlay of this type. On every vkQueueSubmit, the number of nodes in the command graph is accumulated. On every present(), the value is taken as the number of nodes for the whole duration of the frame. - RunningHistogram: A histogram of last N values. Input values are in the [0, 1] range and they are ranked to N buckets for histogram calculation. VulkanSecondaryCommandBufferPoolWaste is an overlay widget of this type. On vkQueueSubmit, the memory waste from command buffer pool allocations is recorded in the histogram. Overlay font is placed in libANGLE/overlay/ which gen_overlay_fonts.py processes to create an array of bits, which is processed at runtime to create the actual font image (an image with 3 layers). The overlay widget layout is defined in overlay_widgets.json which gen_overlay_widgets.py processes to generate an array of widgetss, each of its respective type, and sets their properties, such as color and bounding box. The json file allows widgets to align against other widgets as well as against the framebuffer edges. Two compute shaders are implemented to efficiently render the UI: - OverlayCull: This shader creates a bitset of Text and Graph widgets whose bounding boxes intersect a corresponding subgroup processed by OverlayDraw. This is done only when the enabled overlay widgets are changed (a feature that is not yet implemented) or the surface is resized. - OverlayDraw: Using the bitsets generated by OverlayCull, values that are uniform for each workgroup (set to be equal to hardware subgroup size), this shader loops over enabled widgets that can possibly intersect the pixel being processed and renders and blends in texts and graphs. This is done once per frame on present(). Currently, to enable overlay widgets an environment variable is used. For example: $ export ANGLE_OVERLAY=FPS:VulkanSecondaryCommandBufferPoolWaste $ ./hello_triangle --use-angle=vulkan Possible future work: - On Android, add settings in developer options and enable widgets based on those. - Spawn a small server in ANGLE and write an application that sends enable/disable commands remotely. - Implement overlay for other backends.

They are emulated with Vulkan storage buffers, which do have restrictions. The storage buffers are bound at aligned offsets, and the remaining offsets are passed to the shader as uniform values. This means that the driver uniforms are now also bound to the compute pipeline.

James Darpinian e4109f27 2018-12-13T16:25:53 WebGL: validate texture format matches sampler type WebGL requires that drawing produces INVALID_OPERATION if a texture's format doesn't match the sampler type it is bound to. This is a little confusing because samplers have two attributes that could be called "type": addressing mode (2D/3D/Cube), and component format (float/signed/unsigned/shadow). ANGLE already handled checking the addressing mode; this change adds checking for the component format.

Corentin Wallez f0e89be6 2017-11-08T14:00:32 Use packed enums for the texture types and targets, part 1 In OpenGL there are two enum "sets" used by the API that are very similar: texture types (or bind point) and texture targets. They only differ in that texture types have GL_TEXTURE_CUBEMAP and target have GL_TEXTURE_CUBEMAP_[POSITIVE|NEGATIVE]_[X|Y|Z]. This is a problem because in ANGLE we use GLenum to pass around both types of data, making it difficult to know which of type and target a variable is. In addition these enums are placed somewhat randomly in the space of OpenGL enums, making it slow to have a mapping from texture types to some data. Such a mapping is in hot-code with gl::State::mTextures. This commit stack makes the texture types and target enums be translated to internal packed enums right at the OpenGL entry point and used throughout ANGLE to have type safety and performance gains. This is the first of two commit which does the refactor for all of the validation and stops inside gl::Context. This was the best place to split patches without having many conversions from packed enums to GL enums.

Jamie Madill 888081d5 2018-02-27T00:24:46 D3D11: Refactor dependent Framebuffer state changes. Previously, when a state change would cause a Texture to recreate its storage specific to D3D11, we would use a dependent notification from RenderTarget11 to Framebuffer11 to re-check internal dirty bits. In this new method, we instead set dirty bits on the gl::Frambuffer directly. This also means we use fewer internal objects for these notifications, because we share the same structures between the D3D11 back-end notifications and the top-level notifications we use for Robust init and Framebuffer completeness. This also allows us to get rid of one "if" that we check on every draw call in D3D11. This also introduces a dirty bits guard concept - a shadow set of dirty bits that is checked in dependent state changes to ensure that extra bits aren't set inside syncState. This also implements Framebuffer dirty bits for the D3D9 back-end. This has the side effect of cleaning up the "null colorbuffer" D3D9 workaround.

Jamie Madill d444255a 2018-02-27T22:03:47 Refactor signal utils into Observer pattern. These types were over-generalized. All use cases featured arrays of resources attached to single parent resources. The channel ID is sufficient to identify the child resource in the parent, and having variadic template arguments wasn't necessary. Futhermore we can rename these types to use the common Observer pattern. This should make them more readable to new developers. Also update some classes to inherit from Subject instead of having a member Subject. This cleans up the code in a few places. This should lead to a simpler refactor to allow dependent dirty bits notifications in the Vulkan back-end. In the following patch the signal_utils files will be renamed. They are not renamed in this patch to ensure git history is preserved.
