  Message : Reland "Vulkan: Implement debug markers" This reverts commit 0c01e36783b20a0177c653490cb4f8ea4a896075. Reason for revert: Its dependency that was reverted has now relanded: https://chromium-review.googlesource.com/c/angle/angle/+/1489153 Original change's description: > Revert "Vulkan: Implement debug markers" > > This reverts commit 983e446921946734fe47217c345a8fe2f079319d. > > Reason for revert: Depends on a CL that's reverted: https://chromium-review.googlesource.com/c/angle/angle/+/1470605 > > Original change's description: > > Vulkan: Implement debug markers > > > > Covers both GL_KHR_debug and GL_EXT_debug_marker. > > > > Debug markers are used to specify events or hierarchically categorize a > > set of commands within the command buffer. When debugging, this allows > > for quicker navigation to the draw calls of interest, and otherwise > > provides context to debug output. > > > > Bug: angleproject:2853 > > Change-Id: Id65e11fc877d9e70b6fd0fae7f0bbbcb1164bf10 > > Reviewed-on: https://chromium-review.googlesource.com/c/1403956 > > Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> > > Reviewed-by: Jamie Madill <jmadill@chromium.org> > > Reviewed-by: Geoff Lang <geofflang@chromium.org> > > TBR=geofflang@chromium.org,jmadill@chromium.org,syoussefi@chromium.org > > Change-Id: I7fcfc8683195d396aec61848719f52c0fa049ece > No-Presubmit: true > No-Tree-Checks: true > No-Try: true > Bug: angleproject:2853 > Reviewed-on: https://chromium-review.googlesource.com/c/1470606 > Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> > Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> TBR=geofflang@chromium.org,jmadill@google.com,syoussefi@chromium.org Bug: angleproject:2853 Change-Id: Ie19ae103244d54dcf7108d5f61c24e318fc44057 Reviewed-on: https://chromium-review.googlesource.com/c/1489154 Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Jamie Madill <jmadill@google.com>
