Reland "Vulkan: Fix texture-after-framebuffer sync issues" This is a reland of commit 535cd538f3585b44855647339f04bae1c1acf63a Original change's description: > Vulkan: Fix texture-after-framebuffer sync issues > > In TextureVk::syncState, for various reasons, the underlying image may > need to be respecified. For example because base/max level changed, > usage/create flags have changed, the format needs modification to become > renderable, generate mipmap is adding levels, etc. > > Currently, ANGLE syncs FramebufferVk before TextureVk for the sake of > the deferred clear optimization. This means that if the texture needs > to recreate its underlying image, it needs to do so earlier than its own > syncState, and do so in FramebufferVk::syncState through the > TextureVk::getAttachmentRenderTarget function. > > Over time, TextureVk::getAttachmentRenderTarget was modified to do parts > of what TextureVk::syncState did for this matter as bugs were > discovered, and more continue to be discovered. The bug that prompted > this change is missing image recreation when usage/create flags change. > > In this change, the relevant code in TextureVk::syncState is refactored > in a helper that's called by TextureVk::getAttachmentRenderTarget. This > way, the two functions should always be in agreement, avoiding > TextureVk::syncState recreating the image after > FramebufferVk::syncState, leading to use-after-free bugs. > > Bug: angleproject:4418 > Bug: angleproject:6909 > Bug: chromium:1266094 > Bug: chromium:1296866 > Change-Id: I856a34ca5cf573578c771f5adbeb9208420a3f62 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3557817 > Reviewed-by: Jamie Madill <jmadill@chromium.org> > Reviewed-by: Charlie Lao <cclao@google.com> > Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Bug: angleproject:4418 Bug: angleproject:6909 Bug: chromium:1266094 Bug: chromium:1296866 Change-Id: I0110eab88eb9d8f77e204b84a6e90308e2384fd7 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3572715 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Yuxin Hu <yuxinhu@google.com> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org>
