Change log for October 20, 2017 Vulkan 1.0.64 spec update:

  * Bump API patch number and header version number to 64 for this update.

Github Issues:

  * Add chapter name to the PDF page footer (public pull request 458).
  * Fix several mistaken references to the nonexistent etext:VK_DEVICE_LOST
    status to etext:VK_ERROR_DEVICE_LOST (public pull request 502).
  * Fix description of the tlink:PFN_vkDebugReportCallbackEXT debug report
    callback function pointer to match the validation layer behavior (public
    issue 534).
  * Document experimental KHX extensions and alternate vendor author IDs
    also ending in X in more detail in the <<extensions, Layers &
    Extensions>> appendix, the extensions section of the style guide, and
    the registry schema description document (public issues 536, 580).
  * Fix references to ptext:pDepthStencil to properly refer to
    pname:pDepthStencilState or pname:pRasterizationState as appropriate in
    the slink:VkGraphicsPipelineCreateInfo description (public issue 542).
  * Fix wrong parameter name in slink:VkPipelineMultisampleStateCreateInfo
    valid usage (public pull request 571).

Internal Issues:

  * Update the style guide to describe how to write LaTeX math expressions
    in table cells (internal issue 908).
  * Define how framebuffer-local dependencies work between subpasses with
    the same or different numbers of samples, in the
    slink:VkSubpassDescription and <<synchronization-framebuffer-regions,
    Framebuffer Region Dependencies>> sections. This clarifies which samples
    in an input attachment you are allowed to access after a
    framebuffer-local dependency (internal issue 915).
  * Specify which storage classes can have an initializer in the
    <<spirvenv-module-validation, Validation Rules within a Module>> section
    (internal issue 1023).
  * Use "LOD" consistently for "level-of-detail", to eliminate spelling
    inconsistencies. The term is already standardized in the Glossary
    (internal issue 1027).

Other Issues:

  * Fix false positives in Makefile dependencies when rules fail, by
    deleting partially-made targets.

New Extensions:

  * `VK_AMD_shader_info`

NVIDIA HairWorks is a library for simulating and rendering dynamic hair and fur.
 What's New in 1.4 beta
  • Supports morph target animation (in beta only supported in DirectX11)
  • Change to math types - stops clashes with other modules
  • Miscellaneous bug fixes and improvements
The change in math types means that to upgrade code to use 1.4 you will need to change the gfsdk_ prefixed math types in the following ways
 
  • gfsdk_float2 -> NvHair::Vec2
  • gfsdk_float3 -> NvHair::Vec3
  • gfsdk_float4 -> NvHair::Vec4
  • gfsdk_float4x -> NvHair::Mat4x4
  • gfsdk_quaternion -> NvHair::Quaternion
  • gfsdk_dualquaternion -> NvHair::DualQuaternion
The maths types alias to simple struct types defined in Nv/Common/Math/NvCoMathTypes.h

3D-Tech News Around The Web / AMD Radeon GPU Profiler 1.0.3
« on: October 18, 2017, 09:01:33 PM »
Radeon GPU Profiler 1.0.3


A couple of months on from the release of 1.0.2, we’ve fully baked and sliced 1.0.3 for your low-level DX12- and Vulkan-based performance analysis needs. With some of the functionality that RGP is built on being provided by our driver stack, there are a few things that we’d hoped to get into this release that didn’t quite make it due to an accelerated driver release schedule, but there’s still plenty to talk about for both RGP and the developer panel that provides some of the profiling and settings control.


Radeon GPU Profiler

Radeon GPU Profiler first, there’s now access to system information in the UI on Windows (we’re working on Linux support for that but it’s trickier to get right), you can now see GPU time duration information in user marker regions and groups in the Event timing view, and there’s better sync between some event status information in the Event timing and wavefront occupancy views.

When it comes to usability enhancements, you can now load a profile into RGP by just dragging it onto the RGP executable on Windows, or the open RGP UI on any platform. We also now bring the selected event into the view when using Shift+Left or Shift+Right to jump between them in the wavefront occupancy view. Lastly in the list of nice usability changes worth highlighting, CTRL+T now cycles between time units in any view, so you don’t have to dip into settings to adjust that.
Radeon Developer Panel

Thanks to everyone who asked for a headless version of the Radeon Developer Service. We heard you loud and clear, so now there’s RadeonDeveloperServiceCLI.exe on Windows, and RadeonDeveloperServiceCLI on Linux. We also show you the listening port number in the configuration window just in case you need to know what it is, and we have a fix for drawing the panel properly on lower resolution 720p displays.
More information

As always, you can find out more about RGP, including links to the release binaries on GitHub and the full release notes list, on our product page.

3D-Tech News Around The Web / Vulkan API specifications 1.0.63 released
« on: October 15, 2017, 07:07:36 AM »

Change log for October 13, 2017 Vulkan 1.0.63 spec update:

  * Bump API patch number and header version number to 63 for this update.

Github Issues:

  * Add missing valid usage statements for ptext:maxDescriptorSets*,
    ptext:maxPerStageDescriptorInputAttachments, and
    ptext:maxPerStageResources to slink:VkPipelineLayoutCreateInfo.txt,
    flink:VkComputePipelineCreateInfo, and
    flink:VkGraphicsPipelineCreateInfo (public issue 546).
  * Fix typos in ftext:vkCmdDraw*AMD descriptions (public pull request 549).
  * Fixed flink:vkCmdWriteTimestamp so it is not unnecessarily restricted to
    queues supporting graphics or compute operations (public issue 558).
  * Improvements to valid usage generator for output `*Flags` pointer
    parameters and for some `void *` parameters (public pull requests 560,
    562).
  * Document `altlen` attribute in XML schema as valid C99 syntax and tweak
    `vk.xml` to match (public pull request 566).
  * Clarify when pname:fence is signaled by flink:vkQueueSubmit in a more
    obvious place (public issue 577).

Internal Issues:

  * Specify a whitelist of supported SPIR-V Storage Classes in the
    <<spirvenv-module-validation, Validation Rules within a Module>>
    appendix (internal SPIR-V issue 166).
  * Relax the shared semaphore wait timeout requirement in the
    <<synchronization-semaphores-importing, Importing Semaphore Payloads>>
    section (internal issue 820).
  * Update the <<textures-image-level-selection, Image Level(s) Selection>>
    equations so that the parameters returned by the level-of-detail query
    appear explicitly, also fixing the issue that linear filtering would
    select a level below the base level for magnification (internal issue
    926).
  * Disallow creation of a swapchain with zero pname:imageExtent in
    slink:VkSurfaceCapabilitiesKHR and slink:VkSwapchainCreateInfoKHR
    (internal issue 1020).

Other Issues:

  * Clarify in <<textures-operation-validation,Image View Validation>> that
    the layout of subresources in an image view must have a layout that
    matches that written into the descriptor, and that this section is about
    validating image views, not images.

New Extensions:

  * `VK_EXT_global_priority`

« on: October 12, 2017, 04:27:17 PM »
  ******************************
  * NVIDIA Aftermath(Debugger) *
  ******************************

--- RELEASE NOTES (version 1.3) ---

Features:
o) Added ability to get more information back from GPU in event of page fault - GFSDK_Aftermath_GetPageFaultInformation.
o) Renamed GFSDK_Aftermath_Status to GFSDK_Aftermath_Device_Status - to avoid confusion with GFSDK_Aftermath_Context_Status.
o) Removing VC Runtime dependency (static linked) from non-UWP DLL (still required for UWP).
o) Increased minimum supported driver version to 387.xx
o) Separated GetData from GetDeviceState - so GetDeviceState can be polled without worrying about performance.
o) Updated how to instructions in header.
o) Added APIs to associate a commandlists/deviceContexts with Aftermath (GFSDK_Aftermath_DXxx_CreateContextHandle).
    -> Provides a nice CPU perf boost, as no longer need to lookup the internal Aftermath context.
    -> Simplifies following entrypoints, removing the per DX version ones.

Bugs:
o) API - Unable to export demangled, GFSDK_Aftermath_ContextData::getErrorCode() - now implemented in header.
o) Crash - Crash occured if calling SetEventMarker on a command list after resetting the allocator.
o) API - SetEventMarker now accepts a const void* - previously just a void*.
o) Functionality - D3D12 bundles previously didn't work if the bundle was "baked" (contained 4 or more draws).

Performance:
o) Siginificantly reduced memory footprint of D3D12 "baked" bundles.
o) Increased the CPU performance of Aftermath for D3D11 and D3D12.

Change log for October 6, 2017 Vulkan 1.0.62 spec update:

  * Bump API patch number and header version number to 62 for this update.

Github Issues:

  * Move asciidoc conditionals for `VK_KHR_maintenance1` in
    slink:VkDescriptorSetAllocateInfo so valid usage statements for
    `VK_KHR_push_descriptor` aren't accidentally removed when the first
    extension isn't enabled (public issue 573).
  * Fixed errors in API example code for
    flink:vkUpdateDescriptorSetWithTemplateKHR and
    flink:vkCmdPushDescriptorSetWithTemplateKHR (public issue 577).

Internal Issues:

  * Specify constraints on concurrent access to fences that share payload in
    the <<synchronization-fences-importing, Importing Fence Payloads>> and
    <<synchronization-semaphores-waiting-state, Semaphore State Requirements
    For Wait Operations>> sections (internal issue 820).
  * Define the term "`retired swapchain`", reorganize some swapchain
    language, and improve language for pname:oldSwapchain in
    flink:VkSwapchainCreateInfoKHR, the <<swapchain-wsi-image-create-info>>
    table, flink:vkDestroySwapchainKHR, and flink:vkAcquireNextImage2KHX
    (internal issue 869).
  * Describe in the <<writing-arrays, Describing Properties of Array
    Elements>> section of the style guide how and when to use "`each`" and
    "`any`" to refer to properties of array elements, and make those uses in
    the specification consistent (internal issue 884).
  * Clarified that events cannot be used for cross-queue synchronization in
    the <<synchronization-events, Events>> section and for
    flink:vkCmdWaitEvents (internal issue 970).
  * Add success and error codes to +vk.xml+ for
    flink:vkCreateValidationCacheEXT (internal issue 995).
  * Clarify aspect mask usage for image memory barriers of multi-plane
    images in slink:VkImageSubresourceRange, slink:VkImageMemoryBarrier, and
    the <<textures-layout-validation, Layout Validation>> section (internal
    issue 996).

Other Issues:

  * Fixed typo in flink:VkRenderPassSampleLocationsBeginInfoEXT (renamed
    field pname:pSubpassSampleLocations to
    pname:pPostSubpassSampleLocations).
  * Add missing buffer usage requirements for indirect draws in
    flink:vkCmdDrawIndirect, flink:vkCmdDrawIndirectCountAMD,
    flink:vkCmdDrawIndexedIndirect, and
    flink:vlCmdDrawIndexedIndirectCountAMD.
  * Modify Makefile to allow specification to build in git "`detached HEAD`"
    state.
  * Update valid usage ID generation script to allow recursively operating
    on all `.txt` files in a specified directory, and move the `startVUID`
    tracking information into a separate python file that is automatically
    updated by the script.

New Extensions:

  * Add +vk.xml+ entries for pending `VK_ANDROID_native_buffer` extension
    (note, this extension is not yet enabled).
  * `VK_AMD_shader_image_load_store_lod`

Intel UHD Graphics 630 "Coffee Lake" On Linux:

This morning I delivered the initial Linux processor benchmarks of the Core i7 8700K and Core i5 8400 for the just-launched "Coffee Lake" desktop processors. With these Intel "Gen 8" processors, the integrated "HD Graphics" from Kabylake have been rebranded to "UHD Graphics". While there wasn't any real changes architecturally to the graphics hardware, right now the Linux support isn't quite out-of-the-box.
