Charlie Lao ecc378cc 2025-03-03T16:43:33 Reland "Dont use Subject/Observer for SwapchainImageChanged" This is reland of the following CL https://chromium-review.googlesource.com/c/angle/angle/+/6319893 Because we do deferred ANI (VkAcquireNextImage) call until image is needed, we need a way to force Context to go through FramebufferVk::syncState call (FramebufferVk::syncState calls WindowSurfaceVk::getAttachmentRenderTarget, which end up calling ANI. Right now we uses subject/observer mechanism, by sending angle::SubjectMessage::SwapchainImageChanged to all observers of WindowSurfaceVk. In this case it is egl::Surface. Then eglSurface redirects this message to its observers, which are all gl::Framebuffer's attachments: color, depth, stencil. Even though only color attachment needs to be notified, but because we don't have a separate list of observers, depth/stencil attachment also receive the notification and they early out. Then gl::Framebuffer sets DIRTY_BIT_COLOR_BUFFER_CONTENTS_0 dirty bit and send the angle::SubjectMessage::DirtyBitsFlagged to Context, which dirty DrawFBO and ReadFBO and dirty cached state. Note that this is specific for swap image changed case, there is no surface property change (surface property change will still trigger the subject/observer message with SubjectMessage::SubjectChanged message, but this occurs rarely). This gets worse for apps that uses multiple contexts, for the example pokemon_masters_ex has three contexts, each context has its own default frame buffer that attach to the same surface, and we never remove non-current context from the observer list. This end up with egl::Surface has 12 observers and for every frame, it loop over the list of 12 observers and send message (virtual function call) to each of them. Color attachment also ends up sending two messages to Context, one for Read FBO and another for Draw FBO. There are total 21 virtual function calls. Even for single context usage, you have 6 virtual function calls, for every frame. EGL spec says "an EGLSurface must be current on only one thread at a time", any other context must call EGLMakeCurrent in order to use this surface, which will add all necessary dirty bits at that time. So we really only need to notify current context. In this CL, SwapchainImageChanged no longer uses subject/observer mechanism, so this message is removed. This CL still uses subject/observer mechanism to send DirtyBitsFlagged from Framebuffer back to context. We could call setDrawFramebufferDirty and setReadFramebufferDirty directly, but that will require to remove the "const" decoration out of gl::Context which generates too much code diff, so onStateChange(angle::SubjectMessage::DirtyBitsFlagged) is still used.

Shahbaz Youssefi ecc35205 2024-01-25T23:58:25 Move uniform block dirty bits to State When glUniformBlockBinding changes the mapping from a program uniform block to a buffer binding, all contexts in the share group need to reprocess the affected block index. Prior to this change, the dirty bits that indicated which blocks have their mapping redefined were placed in the program executable, and were reset by the first context that processed them. As a result, the other contexts in the share group where not aware of such modifications. Similarly, when a buffer changed in one context, the mapped program blocks were marked dirty, with similar cross-context issues. In this change, the dirty bits are moved to State, so every context would react to these changes.

Shahbaz Youssefi a1143857 2023-12-18T15:24:42 Fix UBO dirty bits vs PPOs This change fixes propagation of UBO dirty bits (such as through glUniformBlockBinding and glBindBufferRange) to program pipeline objects. Since PPOs concatenate the attached programs' UBOs in a list, a map of program UBO indices to PPO UBO indices is introduced to offset these dirty bits appropriately. Additionally, when the program's executable's buffer bindings change (through glUniformBlockBinding), a notification is send to the PPO to update its executable's buffer binding accordingly (which is otherwise only updated during PPO link).

Shahbaz Youssefi 7b0bb0f6 2023-09-01T13:52:28 Properly "install" program executables According to GL: - The program has an executable - The executable is overwritten during link. - After a failed link, queries of the executable may return half-linked information - On glUseProgram, the executable is installed in the context - On glUseProgramStages, the executable is installed in the program pipeline - After a successful link, the executable is updated wherever the previous executable of the program was installed. This change implements exactly the above: - The program's and the program pipeline's executables are now shared_ptr. References to an executable in the context and PPO are also through a shared_ptr. Installing an executable thus translates to sharing the executable. - The context and PPOs are made to not reference the program directly, but work solely through the executable. As a result, the program is free to create a new executable for link. With this change, the link job will be free to modify the executable as necessary because that will not be accessed until the link is done. Note that previous changes made the backend executable accessed through the frontend one, and moved all link results to the frontend and backend executables as appropriate.

Change the behavior to deinitialize them instead. This change requires the addition of a new observer message, angle::SubjectMessage::TextureIDDeleted, which PLS uses to deinitialize a plane when the app deletes its texture.

Most time it is only swapchain image changes. Right now we are also setting depth/stencil buffer dirty and processing layer count update and color mask and blending update when only color image changed.

It also avoids color mask and blending update (they still gets updated for draw buffer change or draw franmebuffer binding changes).

Charlie Lao b186991a 2022-05-26T11:50:56 Vulkan: Remove non-current vertex array from buffer's observer list When app binds a buffer to many VAOs, any buffer modification have to loop over all VAOs that uses that buffer, even though all these VAOs are not current except one VAO. That causes significant CPU overhead. black_desert_mobile has this type of usage. This CL checks number of observers on each binding and if there are excessive observers, it removes VAO from the buffer's observer list when it becomes non-current and adds back to observer list when it becomes current. This CL reduces CPU overhead of black_desert_mobile (as measured with --offset --minimumgpuwork) from 21ms to 3.69ms, on par with native GLES driver. Note that this CL only touches glBindVertexArrayObject call code path, so no impact to apps not using VAOs. There is also no measurable CPU time regression on a few other app traces that uses VAOs.

Jamie Madill a8f1a916 2021-08-26T17:53:56 GetTexImage: Remove syncState calls & add early error exit. Instead of calling syncState to force the Vulkan staged textures to flush, we ensure the Texture is marked initialized by sending a message up to the Texture when there are no more pending updates. Also adds handling for textures with extra mips. Instead of crashing, we now return an error with a warning. Also adds a test with a texture that has extra (outside the mip chain) defined levels. Also adds a test and handling for empty texture levels. This should lead to more consistent behaviour in the trace test serialization logic, where often the prior logic would behave differently depending on if GetImage was called from MEC or from the serialization code. Also updates the generateMipmap logic to syncState after calling initializeContents so the updates happen in the correct order on Vulkan.

Tim Van Patten e3b9dbef 2021-03-17T18:01:02 Update PPO's executable when attached program is re-linked When a program that's being used by a PPO is successfully re-linked, the PPO's ProgramExecutable needs to be updated. This takes advantage of the subject/observer pattern that's already established between programs and PPOs to ensure only the PPOs that the program is a part of are updated.

Ian Elliott 6eb7756d 2020-08-07T17:41:39 Vulkan: tell ContextVk when swapchain is re-created For an app that only draws to the swapchain, if the swapchain is recreated with a different rotation (as done by the ANGLE perf tests when switching from Angry Birds 2 to Candy Crush), ContextVk is not informed, and so the new rotation is ignored. Use the subject-observer pattern to set the appropriate dirty bits.
