v1.2.0

Graphics API Debugger, version 1.2.0 contains a number of new features, bug fixes and optimizations to trace and replay.

New Features:

• New UI to pick the device used for replay and new support for OpenGL ES on-device replay
• New experimental support for OpenGL ES Mid-Execution capture
• Trace dialog is now uniform across all trace targets

Vulkan

• Added support for replaying to the screen on Windows and Linux
• Added the option to export replay payloads for later replay with gapir
• Add overdraw as option to GAPID UI framebuffer view
• Vulkan validation layer output is now included in the Report view

Command Line Tools

• New gapit stats verb for printing capture statistics
• New gapit memory verb for a breakdown of Vulkan memory usage
• gapit can now replace shader source in a .gfxtrace
• gapit screenshot can now specify an attachment
• gapit state filtering now supports wildcards
• VkPipelines are now listed as a resource type
• gapit screenshot can now create multiple screenshots in one call

Misc

• Add an option to GAPID to disable unknown extensions.

Optimizations:

• Only take the slow-path in MutationCmdsFor if we really have to.
• Don't encode commands pre MEC
• Drop the global lock around most of the Vulkan API commands
• Another way to drop raw bytes of the capture data
• Add @spy_disabled annotation to subroutines.
• Pre-resolve dependency graph
• Switched the map iteration template to refs instead of copies.
• Add Dense map to the API language.
• Limit the size of replay resource data chunks to reduce memory usage
• Do not cache the instruction builder for replay execution
• Fix to reduce memory usage of gapis video.
• Vulkan: Reduce DCE memory usage
• Optimize resource hashing
• Elide ALL commands that we are not trying to trace.
• Optimize byte slice copies

Fixes:

• Increase the connect timeout to the gapii socket.
• Linux: Be more aggressive about keeping the memory tracker on.
• Return better error messages from remote ssh connection
• Fix type cast panic (bug #2190)
• Close ssh tunnel when either end closes the connection
• Fix an issue with linux remote-ssh package listing.
• Workaround an issue in golang 1.10.3 where a 4GB file is truncated.
• Use a more robust way to retrieve screen states
• Allow more memory in gapir if we are on desktop.
• Add support for rendering during replay to the surface
• Don't merge stdout/stderr on remote device-info.
• Overdraw: Check for format support and convert if necessary
• gapii/client: Use a timeout for the Dial
• Create gapic GL contexts ourselves on Linux.
• Fix command tree grouping by frame.
• Fix a bug in virtual swapchain
• Add a workaround for some Linux drivers.

OpenGL ES Fixes:

• Correctly replay uniform block bindings.
• Fix scissor/viewport resetting

Vulkan Fixes:

• Fix an overrun in the dependencySync.
• Smarter check for temporary shader modules, renderpasses etc.

• Cache the base pipeline only if the creating pipeling has derivative bit
• vkGetPhysicalDevice*PresentationSupportKHR reads and validate the physical device
• Added vkCmdBlitImage api implementation
• Fix typo in descriptor api.
• Update how we handle descriptor sets again.
• Fix wrong descriptor set indices when binding descriptor sets
• Remove explicit write in doVkCmdFillBuffer.
• Make sure we don't use uninitialized memory in BaseSwapchain::Destroy
• Fix bugs about linear images
• Warn when imageview aspect flags not subset of image aspects
• A few more small fixes around images and descriptor sets.
• Add a couple of checks around image usage.
• Copy depth aspect by rendering in overdraw
• Use framebuffer extent in depth aspect copy, fixes #2071
• Fix a DCE bug with vkCreateBufferView
• Reduce the num of cmds for state rebuilding again
