Reland "[gpu] Use DawnSharedTextureHolder in D3DImageBacking" This is a reland of commit 036455e7ccdeb88ee2f2e27794fa32963775ddaa Diff from original (PS1-PS4): - Fix the lock mechanism in ProduceDawn. - Cache SharedTextureMemory in DawnSharedTextureHolder only for Graphite devices. Original change's description: > [gpu] Use DawnSharedTextureHolder in D3DImageBacking > > Use DawnSharedTextureHolder that caches wgpu::Texture and > SharedTextureMemory per device within D3dImageBacking. This will be > helpful as we want to cache textures for the lifetime of the backing > instead of the representation. Also, adjust dxgi shared handle > state to cache shared texture memory properly. > > Also add tracking for begin/end accesses for D3DBacking::DawnRep > so that the SharedTextureMemory::Begin/EndAccess are called only once > when cached. > > NOTE: The Begin/EndAccess tracking will be moved to > DawnSharedTextureHolder in follow-up(s) > > Bug: 348598119 > Change-Id: I4b43587c07a97917a32c50078319e7efc7896a7d > Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/5685692 > Reviewed-by: Sunny Sachanandani <sunnyps@chromium.org> > Commit-Queue: Saifuddin Hitawala <hitawala@chromium.org> > Cr-Commit-Position: refs/heads/main@{#1327737} Bug: 348598119 Change-Id: Ie6a96cf18a8351eec5adcbc52ea2bce4e461878d Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/5724830 Commit-Queue: Saifuddin Hitawala <hitawala@chromium.org> Reviewed-by: Sunny Sachanandani <sunnyps@chromium.org> Cr-Commit-Position: refs/heads/main@{#1330526}
Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.
The project's web site is https://www.chromium.org.
To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.
Documentation in the source is rooted in docs/README.md.
Learn how to Get Around the Chromium Source Code Directory Structure.
For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
