• Fixed PVRVk getCacheMaxDataSize(), initializing dataSize parameter handed to vkGetPipelineCacheData to identify cases where pipeline cached data has size 0.
• Fixed over 170 compilation warnings.

Examples

• Added new Vulkan example: Antialiasing (MSAA, FXAA, TAA).
• Fixed VulkanTimelineSemaphores example crashing on early exit when the extension is not supported.
• Fixed VulkanSubgroups example no ouput on BXM-8-256: Workgroup width was being set to zero during setup.
• Fixed OpenGLESPostProcessing and VulkanPostProcessing small artifacts on the edge of the mesh when no post processing method is being applied.
• Fixed making several SDK demos time deterministic when using the -forceframetime parameter (OpenGLESDeferredShading, OpenGLESGameOfLife, OpenGLESParticleSystem, VulkanDeferredShading, VulkanDeferredShadingPFX, VulkanGameOfLife, VulkanGnomeHorde, ParticleSystemGPU).
• Fixed VulkanHelloRayTracing various buffers being built with not optimal memory properties.

PVRTune v14.158

GUI

• Implement PVRTune & Qt-6.2: high resolution graphs when DPI scaling. Graphs no longer look increasingly blurry as OS DPI scaling is increased.
• Implement Find results: allow multi-select and copy.
• Fix unable to connect to server if a SSH device with the same IP address is placed inside the SSH Devices list. Replaced the “Connect to:” ComboBox, Connect and New Device buttons, and static Shortcuts “localhost” and “Android USB device”, with a new more intuitive list of connect/load options alongside the existing Shortcuts list. Update Menu offerings to match. “Override PVRPerfServer Settings” and “Schedule Resource Capture” moved to the bottom of the screen, with the options now hidden until enabled. Improved information available about Shortcuts.
• Fix allocated Streams memory leak.
• Implement allow multi-select and hide/show (using space bar or enter key) of timelines in the Timelines docking window.
• Fix excessive Qt text eliding in Properties docking window.
• Fix Counter Table “Hide Inactive”, “Show Visible Only” and switching counter group now all update the visible counters appropriately.
• Fix Resource Viewer is always synchronising GUI and Engine. Improves performance of GUI.

PVRScope

• Implement  PVRScopeStats: add EPVRScopeEvent count enum value.

PVRCarbon v0.13

General

• Expand Frame analysis’ Vulkan coverage.
• Update Vulkan support to 1.3.283.

Export To C++

• Add support for eglImage* calls that make use of OpenGL ES textures and renderbuffers as their client buffers.
• Add support for eglImage* calls that make use of EGL_NATIVE_BUFFER_ANDROID client buffers.
• Add support for eglImage* calls that make use of EGL_LINUX_DMA_BUF_EXT client buffers.
• Fix disabling of unsupported Vulkan device features that have been promoted to core.
• Fix disabling of unsupported Vulkan device features when vkGetPhysicalDeviceFeatures2 is unsupported by falling back to vkGetPhysicalDeviceFeatures2KHR.
• Improve the tidying up of platform resources (e.g. windows) in exported code.
• Add RISC-V cmake toolchain file to cmake/toolchains under the exported code directory.

Player

• Add command-line option --export-shaders for exporting the recorded source/data for shaders to files allowing for modification.
• Add command-line option --import-shaders for importing shaders previously exported with --export-shaders. The imported shaders will then be used for playback overriding the recorded source/data.
• Rename command-line option --drm-device to --buffer-drm-device.
• Add support for playing back EGLNativePixmapTypeREL pixmaps (if supported by the playback device). By default /dev/dri/card0 will be used but a different device can be specified using --pixmap-drm-device=<value>
• Improve the DRM dumb buffer implementation used for native buffer playback so it no longer defaults to /dev/dri/card0 but iterates over the devices for one with support.
• Add support for allocating DMA buffers from a DMA heap as an alternative to DRM dumb buffers for native buffer playback. By default /dev/dma_heap/system will be used but a different heap can be specified using --buffer-dma-heap=<value>. The player will default to DRM dumb buffers if a device can be found with support, otherwise, the DMA heap implementation will be used. Either implementation can be forced via --buffer-impl.
• Add support for transcoding EGL Image native buffer data during playback if the platform does not support the recorded format.
• Fix the default mode used for --dump-gpu-timestamps.
• Add support for frame GPU timing information via --dump-gpu-timestamps for OpenGL ES for platforms that support EGL_ANDROID_GLES_layers. See --dump-gpu-timestamps command-line description in the documentation for more information.
• Add support for using --dump-gpu-timestamps alongside --offscreen.
• Add support for emulating EGL Images backed by native buffers on platforms that don’t support EGL_EXT_image_dma_buf_import and EGL_ANDROID_image_native_buffer.
• Fix playback of native buffers with formats AHARDWAREBUFFER_FORMAT_YCrCb_420_SP and AHARDWAREBUFFER_FORMAT_YV12 on Android.
• Fix playback of Vulkan sparse image memory bindings.
• Add support for enabling VK_NV_ray_tracing_validation if supported when using --enable-api-debug-report.
• Add support for retrying failed memory map requests when VK_EXT_map_memory_placed is used to request a particular virtual address.
• Add support for VkBindMemoryStatusKHR from VK_KHR_maintenance6.

Recorder

• Increase the overridden alignment values to 4096. The overridden alignment values returned by PVRCarbon specify the required alignment, in bytes, of the offset within an allocation required for binding a resource. The increase improves the portability of recordings.
• Add overrides for the alignments required for texel buffer offsets.
• Improve the robustness of serialising Vulkan structures with members which can be ignored.
• Fix recording applications which use VK_EXT_descriptor_buffer.
• Optimise the state output for Vulkan recordings that don’t begin at frame 0. State is now written out on a per-object basis when needed instead of the entirety being written up front.
• Add support for recording EGLNativePixmapTypeREL pixmaps.

GUI

• Fix various remote recording/playback connection issues.

Frame Analysis

• Fix an issue where cubemap images could not be viewed using the cubemap viewer.
• Fix a number of task list issues when analysing applications using Vulkan debug groups.
• Improve the handling of “top-level” commands showing the result of their “nested” commands e.g. vkCmdExecuteCommands, vkQueueSubmit, vkQueueSubmit2, vkQueueSubmit2KHR or Vulkan debug groups.
