PVRCarbon v0.11

General

  • Add vkQueueWaitIdle to list of custom delimiters.

CLI

  • Add Android command-line binaries for PVRCarbonFrameAnalysis, PVRCarbonTrim, and PVRCarbonToCpp. These are intended to be ran from an adb shell on powerful rooted Android devices for times where analysis/trimming operations can’t be performed on Linux/Windows platforms.
  • Add command-line option --frame to PVRCarbonFrameAnalysis to specify the frame to analyse.
  • Fix invalid unordered_map<K, T> key error seen with PVRCarbonToCpp when exporting some Vulkan recordings with the --disable-surface-replacement option.
  • Improve validation of --uid-range and --frame-range command-line arguments.

Export To C++

  • Improve maximum path length handling.
  • Improve buffer device address handling.
  • Add support for VK_KHR_ray_tracing_pipeline and VK_KHR_acceleration_structure.

GUI

Frame Analysis

  • Add data viewer to Buffer objects.
  • Fix displaying OpenGL ES draw indirect data in the Input Assembly widget.
  • Add support for viewing vertex attribute data.
  • Add support for viewing uniform, uniform buffer, and storage buffer data.
  • Fix crashes seen when exporting some tables to file.

Layers

  • Add support for handling and updating VkImageFormatListCreateInfo in the format emulation layer.
  • Add VK_LAYER_POWERVR_gpu_timestamps which is a Vulkan layer that can be used to provide accurate timing information using Vulkan’s timestamp queries mechanism.

Player

  • Add option --api-debug-report-level to define the severity of messages returned by the Vulkan validation layers when --enable-api-debug-report is enabled. The player now defaults to showing errors only.
  • Fix a bug in --capture-frames where the last capture may not be written to file.
  • Remove option --ignore-capture-replay-compatibility. The player will now warn if the playback platform is different to the recorded platform but will attempt to use recorded device addresses if the capture replay feature is supported.
  • Rename --show-windows to --create-windows and clarify its behaviour in the documentation.
  • Add --hide-created-windows option to hide native windows on their creation. Currently only implemented for Windows.
  • Add filtering of EGL_CONTEXT_OPENGL_NO_ERROR_KHR from eglCreateContext calls if EGL_KHR_create_context_no_error is unsupported.
  • Add command-line option --drm-device to allow the user to override the default DRM device /dev/dri/card0 used for creating DMA buffers when playing back native buffers.
  • Improve the selection of physical devices to better match the physical devices used at record time.
  • Improve the robustness of the synchronisation used when rendering offscreen with --offscreen.
  • Add command-line options --dump-gpu-timestamps, --dump-gpu-timestamps-path and --dump-gpu-timestamps-base-filename which can be used to enable and configure the use of VK_LAYER_POWERVR_gpu_timestamps to provide accurate timing information during playback of recordings.

Recorder

  • Disable VK_EXT_shader_module_identifier during recording as it produces non-portable recordings. This extension and its features can be enabled by setting the disable_identifiers config option to false.
  • Add config option PVRCARBON_native_buffer_drm_device to define the DRM device to use. If undefined, PVRCarbon will query /dev/dri/card0 - /dev/dri/card9 to find the device.

Trimming

  • Add support for Vulkan timeline semaphores.
  • Fix screenshot saving during trimming.
  • Add command line argument --strip-recorded-framebuffers to strip screenshots while trimming.
  • Add support for VK_EXT_debug_utils and VK_EXT_debug_report.
  • Improve the selection of queues used for trimmed resource initialisation.
  • Add support for VK_KHR_ray_tracing_pipeline and VK_KHR_acceleration_structure.
  • Add support for OpenGL ES sync objects.
