Tom Sepez 25390156 2025-08-21T00:13:19 Suppress unsafe buffers on a file-by-file basis in src/ [1 of N] In this CL, we suppress many files but stop short of actually enabling the warning by not removing the line from the unsafe_buffers_paths.txt file. That will happen in a follow-on CL, along with resolving any stragglers missed here. This is mostly a manual change so as to familiarize myself with the kinds of issues faced by the Angle codebase when applying buffer safety warnings. -- Re-generate affected hashes. -- Clang-format applied to all changed files. -- Add a few missing .reserve() calls to vectors as noticed. -- Fix some mismatches between file names and header comments. -- Be more consistent with header comment format (blank lines and trailing //-only lines when a filename comment adjoins license boilerplate).

Charlie Lao d8dc3cc2 2025-08-02T12:02:20 Remove shared context lock from glVertexAttrib{I}Format This CL removes shared context lock from glVertexAttribFormat() and glVertexAttribIFormat() APIs, since they no longer access anything outside VertexArrayPrivate. The main problem I had run into is validation code. Before this CL, ValidateIntegerVertexFormat() needs context's mStateCache for mCachedVertexAttribTypesValidation and mCachedIntegerVertexAttribTypesValidation. Given these two cached value are constant after initialization, in this CL, I have moved them to PrivateStateCache. PrivateStateCache argument is added to ValidateVertexAttribFormat() and ValidateVertexAttribIFormat() to get them access to mCachedIntegerVertexAttribTypesValidation.

Chris Dalton 0f356a34 2025-04-02T14:14:43 Update invalidation commands to disable PLS Previously, commands that flush or invalidate tiled memory were specified to generate an error if issued while PLS was active. Remove all provisions around Flush(), Finish() and ClientWaitSync(), and add a test to ensure these commands have no effect on PLS. The reason we can make this change now is because we no longer support EXT_shader_pixel_local_storage, which previously prevented us from allowing these 3 commands. Update the invalidation commands to disable PLS instead. This is more in line with the general design pattern of PLS. Update the wording of the spec to reflect this better organization. Also clean up some legacy code that was no longer used.

Cody Northrop a1c9ba70 2022-04-04T11:29:13 Update validation of glFramebufferTextureLayer for cube maps The ES 3.2 spec explicitly mentions cube map parameters for the call: For cube map textures, layer is translated into a cube map face as described in table 8.24. For cube map array textures, layer is translated into an array layer and a cube map face as described for layer-face numbers in section 8.5.3 but does not list it when enumerating errors: An INVALID_OPERATION error is generated if texture is non-zero and is not the name of a three-dimensional, two-dimensional array, two-dimensional multisample array or cube map array texture. There is a bug filed about this: https://gitlab.khronos.org/opengl/API/-/issues/134 Per discussion, it should not be an error to use a cube map with glFramebufferTextureLayer. It will be fixed in the spec.

Debug::insertPerfWarning() is invoked from multiple places, such as TextureVK, ContextVK, adding an extra entryPoint function parameter in these files will need extra investigations. I am passing the entryPoint name GLInvalid as a temp workaround. 2.ErrorSet::hangleError() is invoked from multiple Context*.cpp files, adding an extra entryPoint function parameter in these files will need extra investigations. I am passing the entryPoint name GLInvalid as a temp workaround. 3. Debug::insertMessage(), Debug::popGroup(), Debug::pushGroup() can be invoked from more than one GL entry points, e.g. Debug::pushGroup() can be invoked from either GL_APIENTRY GL_PushDebugGroup() or GL_APIENTRY GL_PushDebugGroupKHR() through context->pushDebugGroup() call. Right now the same entry point name glPushDebugGroup will be printed out in the error message for both cases. However, we should be able to tell the actual entry point by checking which version: KHR version or core version the application uses, and this helps avoid the confusion. For now we will let the same entry point name getting printed for both cases.

Cody Northrop 0bd5cac2 2021-08-06T17:56:58 Allow BufferSubData with persistently mapped buffers Per the GL_EXT_buffer_storage extension: What commands are affected by the relaxed errors for persistently mapped buffers? RESOLVED: In GL 4.5 the following commands have the relaxed language BufferSubData, ClearBufferSubData, CopyBufferSubData, GetBufferSubData and InvalidateBufferSubData. Of these commands the only ones that apply to ES 3.1 are BufferSubData and CopyBufferSubData. However, if additional extensions add any of the other commands and EXT_buffer_storage is supported, they would have the same behavior in ES. Therefore we need to allow BufferSubData and CopyBufferSubData on persistently mapped buffers. Current we fail these scenarios in validation. This was detected when running Fortnite on Android using the game's GLES backend. Also added two tests: - StorageCopyBufferSubDataMapped to recreate the exact Fortnite scenario using glCopyBufferSubData. - StorageBufferSubDataMapped is a contrived case to cover glBufferSubData Test: BufferStorageTestES3.StorageCopyBufferSubDataMapped/* Test: BufferStorageTestES3.StorageBufferSubDataMapped/* Bug: b/180418810 Bug: angleproject:5658 Change-Id: Ib678e84f367934656ec10f0f4ad0d35ac687f0b0 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3078316 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Tim Van Patten <timvp@google.com> Commit-Queue: Cody Northrop <cnorthrop@google.com>
