+= Vulkan on Android Implementor's Guide =
+:toc: right
+:numbered:
+:revnumber: 5
+
+This document is intended for GPU IHVs writing Vulkan drivers for Android, and OEMs integrating them for specific devices. It describes how a Vulkan driver interacts with the system, how GPU-specific tools should be installed, and Android-specific requirements.
+
+This is still a fairly rough draft; details will be filled in over time.
+
+== Architecture ==
+
+The primary interface between Vulkan applications and a device's Vulkan driver is the loader, which is part of AOSP and installed at +/system/lib[64]/libvulkan.so+. The loader provides the core Vulkan API entry points, as well as entry points of a few extensions that are required on Android and always present. In particular, the window system integration (WSI) extensions are exported by the loader and primarily implemented in it rather than the driver. The loader also supports enumerating and loading layers which can expose additional extensions and/or intercept core API calls on their way to the driver.
+
+The NDK will include a stub +libvulkan.so+ exporting the same symbols as the loader. Calling the Vulkan functions exported from +libvulkan.so+ will enter trampoline functions in the loader which will dispatch to the appropriate layer or driver based on their first argument. The +vkGet*ProcAddr+ calls will return the function pointers that the trampolines would dispatch to, so calling through these function pointers rather than the exported symbols will be slightly more efficient since it skips the trampoline and dispatch.
+
+=== Driver Enumeration and Loading ===
+
+Android expects the GPUs available to the system to be known when the system image is built, so its driver enumeration process isn't as elaborate as other platforms. The loader will use the existing HAL mechanism (see https://android.googlesource.com/platform/hardware/libhardware/+/lollipop-mr1-release/include/hardware/hardware.h[hardware.h]) for discovering and loading the driver. As of this writing, the preferred paths for 32-bit and 64-bit Vulkan drivers are:
+
+    /vendor/lib/hw/vulkan.<ro.product.platform>.so
+    /vendor/lib64/hw/vulkan.<ro.product.platform>.so
+
+where +<ro.product.platform>+ is replaced by the value of the system property of that name. See https://android.googlesource.com/platform/hardware/libhardware/+/lollipop-mr1-release/hardware.c[libhardware/hardware.c] for details and supported alternative locations.
+
+The Vulkan +hw_module_t+ derivative is currently trivial. If support for multiple drivers is ever added, the HAL module will export a list of strings that can be passed to the module +open+ call. For the time being, only one driver is supported, and the constant string +HWVULKAN_DEVICE_0+ is passed to +open+.
+
+The Vulkan +hw_device_t+ derivative corresponds to a single driver, though that driver can support multiple physical devices. The +hw_device_t+ structure will be extended to export +vkGetGlobalExtensionProperties+, +vkCreateInstance+, and +vkGetInstanceProcAddr+ functions. The loader will find all other +VkInstance+, +VkPhysicalDevice+, and +vkGetDeviceProcAddr+ functions by calling +vkGetInstanceProcAddr+.
+
+=== Layer Discovery and Loading ===
+
+Android's security model and policies differ significantly from other platforms. In particular, Android does not allow loading external code into a non-debuggable process on production (non-rooted) devices, nor does it allow external code to inspect or control the process's memory/state/etc. This includes a prohibition on saving core dumps, API traces, etc. to disk for later inspection. So only layers delivered as part of the application will be enabled on production devices, and drivers must also not provide functionality that violates these policies.
+
+There are three major use cases for layers:
+
+1. Development-time layers: validation layers, shims for tracing/profiling/debugging tools, etc. These shouldn't be installed on the system image of production devices: they would be a waste of space for most users, and they should be updateable without requiring a system update. A developer wishing to use one of these during development has the ability to modify their application package (e.g. adding a file to their native libraries directory). IHV and OEM engineers who are trying to diagnose failures in shipping, unmodifiable apps are assumed to have access to non-production (rooted) builds of the system image.
+
+2. Utility layers, such as a layer that implements a heap for device memory. These layers will almost always expose extensions. Developers choose which layers, and which versions of those layers, to use in their application; different applications that use the same layer may still use different versions. Developers will choose which of these layers to ship in their application package.
+
+3. Injected layers, like framerate, social network, or game launcher overlays, which are provided by the user or some other application without the application's knowledge or consent. These violate Android's security policies and will not be supported.
+
+In the normal state the loader will only search in the application's native library directory for layers; details are TBD but it will probably just try to load any library with a name matching a particular pattern(e.g. +libvklayer_foo.so+). It will probably not need a separate manifest file; the developer deliberately included these layers, so the reasons to avoid loading libraries before enabling them don't apply.
+
+On debuggable devices (+ro.debuggable+ property exists and is non-zero, generally rooted or engineering builds) or debuggable processes (+prctl(PR_GET_DUMPABLE)==1+, based on the application's manifest), the loader may also search an adb-writeable location on /data for layers. It's not clear whether this is useful; in all the cases it could be used, the layer could be just as easily be put in the application's native library directory.
+
+Finally, the loader may include a built-in validation layer that it will enable based on settings in the Developer Options menu, which would send validation errors or warnings to the system log. Drivers may be able to emit additional hardware-specific errors/warnings through this mechanism. This layer would not be enumerated through the API. This is intended to allow cooperative end-users to collect extra information about failures from unmodified applications on unmodified devices to aid triage/diagnosis of difficult-to-reproduce problems. The functionality would be intentionally limited to minimize security and privacy risk.
+
+Our goal is to allow layers to be ported with only build-environment changes between Android and other platforms. This means the interface between layers and the loader must match the interface used by the LunarG loader. Currently, the LunarG interface has a few deficiencies and is largely unspecified. We intend to work with LunarG to correct as many deficiencies as we can and to specify the interface in detail so that layers can be implemented without referring to the loader source code.
+
+== Window System Integration ==
+
+The +vk_wsi_swapchin+ and +vk_wsi_device_swapchain+ extensions will primarily be implemented by the platform and live in +libvulkan.so+. The +VkSwapchain+ object and all interaction with +ANativeWindow+ will be handled by the platform and not exposed to drivers. The WSI implementation will rely on a few private interfaces to the driver for this implementation. These will be loaded through the driver's +vkGetDeviceProcAddr+ functions, after passing through any enabled layers.
+
+Implementations may need swapchain buffers to be allocated with implementation-defined private gralloc usage flags. When creating a swapchain, the platform will ask the driver to translate the requested format and image usage flags into gralloc usage flags by calling
+[source,c]
+----
+VkResult VKAPI vkGetSwapchainGrallocUsageANDROID(
+    VkDevice            device,
+    VkFormat            format,
+    VkImageUsageFlags   imageUsage,
+    int*                grallocUsage
+);
+----
+The +format+ and +imageUsage+ parameters are taken from the +VkSwapchainCreateInfoKHR+ structure. The driver should fill +*grallocUsage+ with the gralloc usage flags it requires for that format and usage. These will be combined with the usage flags requested by the swapchain consumer when allocating buffers.
+
++VkNativeBufferANDROID+ is a +vkCreateImage+ extension structure for creating an image backed by a gralloc buffer. This structure is provided to +vkCreateImage+ in the +VkImageCreateInfo+ structure chain. Calls to +vkCreateImage+ with this structure will happen during the first call to +vkGetSwapChainInfoWSI(.. VK_SWAP_CHAIN_INFO_TYPE_IMAGES_WSI ..)+. The WSI implementation will allocate the number of native buffers requested for the swapchain, then create a +VkImage+ for each one.
+
+[source,c]
+----
+typedef struct {
+    VkStructureType             sType; // must be VK_STRUCTURE_TYPE_NATIVE_BUFFER_ANDROID
+    const void*                 pNext;
+
+    // Buffer handle and stride returned from gralloc alloc()
+    buffer_handle_t             handle;
+    int                         stride;
+
+    // Gralloc format and usage requested when the buffer was allocated.
+    int                         format;
+    int                         usage;
+} VkNativeBufferANDROID;
+----
+
+TBD: During swapchain re-creation (using +oldSwapChain+), we may have to defer allocation of new gralloc buffers until old buffers have been released. If so, the +vkCreateImage+ calls will be deferred until the first +vkAcquireNextImageWSI+ that would return the new image.
+
+When creating a gralloc-backed image, the +VkImageCreateInfo+ will have:
+----
+  .imageType           = VK_IMAGE_TYPE_2D
+  .format              = a VkFormat matching the format requested for the gralloc buffer
+  .extent              = the 2D dimensions requested for the gralloc buffer
+  .mipLevels           = 1
+  .arraySize           = 1
+  .samples             = 1
+  .tiling              = VK_IMAGE_TILING_OPTIMAL
+  .usage               = VkSwapChainCreateInfoWSI::imageUsageFlags
+  .flags               = 0
+  .sharingMode         = VkSwapChainCreateInfoWSI::sharingMode
+  .queueFamilyCount    = VkSwapChainCreateInfoWSI::queueFamilyCount
+  .pQueueFamilyIndices = VkSwapChainCreateInfoWSI::pQueueFamilyIndices
+----
+
++vkAcquireImageANDROID+ acquires ownership of a swapchain image and imports an
+externally-signalled native fence into both an existing VkSemaphore object
+and an existing VkFence object:
+
+[source,c]
+----
+VkResult VKAPI vkAcquireImageANDROID(
+    VkDevice            device,
+    VkImage             image,
+    int                 nativeFenceFd,
+    VkSemaphore         semaphore,
+    VkFence             fence
+);
+----
+
+This function is called during +vkAcquireNextImageWSI+ to import a native
+fence into the +VkSemaphore+ and +VkFence+ objects provided by the
+application. Both semaphore and fence objects are optional in this call. The
+driver may also use this opportunity to recognize and handle any external
+changes to the gralloc buffer state; many drivers won't need to do anything
+here. This call puts the +VkSemaphore+ and +VkFence+ into the same "pending"
+state as +vkQueueSignalSemaphore+ and +vkQueueSubmit+ respectively, so queues
+can wait on the semaphore and the application can wait on the fence. Both
+objects become signalled when the underlying native fence signals; if the
+native fence has already signalled, then the semaphore will be in the signalled
+state when this function returns. The driver takes ownership of the fence fd
+and is responsible for closing it when no longer needed. It must do so even if
+neither a semaphore or fence object is provided, or even if
++vkAcquireImageANDROID+ fails and returns an error. If +fenceFd+ is -1, it
+is as if the native fence was already signalled.
+
++vkQueueSignalReleaseImageANDROID+ prepares a swapchain image for external use, and creates a native fence and schedules it to be signalled when prior work on the queue has completed.
+
+[source,c]
+----
+VkResult VKAPI vkQueueSignalReleaseImageANDROID(
+    VkQueue             queue,
+    uint32_t            waitSemaphoreCount,
+    const VkSemaphore*  pWaitSemaphores,
+    VkImage             image,
+    int*                pNativeFenceFd
+);
+----
+
+This will be called during +vkQueuePresentWSI+ on the provided queue. Effects are similar to +vkQueueSignalSemaphore+, except with a native fence instead of a semaphore. The native fence must: not signal until the +waitSemaphoreCount+ semaphores in +pWaitSemaphores+ have signaled. Unlike +vkQueueSignalSemaphore+, however, this call creates and returns the synchronization object that will be signalled rather than having it provided as input. If the queue is already idle when this function is called, it is allowed but not required to set +*pNativeFenceFd+ to -1. The file descriptor returned in +*pNativeFenceFd+ is owned and will be closed by the caller. Many drivers will be able to ignore the +image+ parameter, but some may need to prepare CPU-side data structures associated with a gralloc buffer for use by external image consumers. Preparing buffer contents for use by external consumers should have been done asynchronously as part of transitioning the image to +VK_IMAGE_LAYOUT_PRESENT_SRC_KHR+.

+<div id="preamble">
+<div class="sectionbody">
+<div class="paragraph"><p>This document is intended for GPU IHVs writing Vulkan drivers for Android, and OEMs integrating them for specific devices. It describes how a Vulkan driver interacts with the system, how GPU-specific tools should be installed, and Android-specific requirements.</p></div>
+<div class="paragraph"><p>This is still a fairly rough draft; details will be filled in over time.</p></div>
+</div>
+</div>
+<div class="sect1">
+<h2 id="_architecture">1. Architecture</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>The primary interface between Vulkan applications and a device&#8217;s Vulkan driver is the loader, which is part of AOSP and installed at <span class="monospaced">/system/lib[64]/libvulkan.so</span>. The loader provides the core Vulkan API entry points, as well as entry points of a few extensions that are required on Android and always present. In particular, the window system integration (WSI) extensions are exported by the loader and primarily implemented in it rather than the driver. The loader also supports enumerating and loading layers which can expose additional extensions and/or intercept core API calls on their way to the driver.</p></div>
+<div class="paragraph"><p>The NDK will include a stub <span class="monospaced">libvulkan.so</span> exporting the same symbols as the loader. Calling the Vulkan functions exported from <span class="monospaced">libvulkan.so</span> will enter trampoline functions in the loader which will dispatch to the appropriate layer or driver based on their first argument. The <span class="monospaced">vkGet*ProcAddr</span> calls will return the function pointers that the trampolines would dispatch to, so calling through these function pointers rather than the exported symbols will be slightly more efficient since it skips the trampoline and dispatch.</p></div>
+<div class="sect2">
+<h3 id="_driver_enumeration_and_loading">1.1. Driver Enumeration and Loading</h3>
+<div class="paragraph"><p>Android expects the GPUs available to the system to be known when the system image is built, so its driver enumeration process isn&#8217;t as elaborate as other platforms. The loader will use the existing HAL mechanism (see <a href="https://android.googlesource.com/platform/hardware/libhardware/+/lollipop-mr1-release/include/hardware/hardware.h">hardware.h</a>) for discovering and loading the driver. As of this writing, the preferred paths for 32-bit and 64-bit Vulkan drivers are:</p></div>
+<div class="literalblock">
+<div class="content monospaced">
+<pre>/vendor/lib/hw/vulkan.&lt;ro.product.platform&gt;.so
+/vendor/lib64/hw/vulkan.&lt;ro.product.platform&gt;.so</pre>
+</div></div>
+<div class="paragraph"><p>where <span class="monospaced">&lt;ro.product.platform&gt;</span> is replaced by the value of the system property of that name. See <a href="https://android.googlesource.com/platform/hardware/libhardware/+/lollipop-mr1-release/hardware.c">libhardware/hardware.c</a> for details and supported alternative locations.</p></div>
+<div class="paragraph"><p>The Vulkan <span class="monospaced">hw_module_t</span> derivative is currently trivial. If support for multiple drivers is ever added, the HAL module will export a list of strings that can be passed to the module <span class="monospaced">open</span> call. For the time being, only one driver is supported, and the constant string <span class="monospaced">HWVULKAN_DEVICE_0</span> is passed to <span class="monospaced">open</span>.</p></div>
+<div class="paragraph"><p>The Vulkan <span class="monospaced">hw_device_t</span> derivative corresponds to a single driver, though that driver can support multiple physical devices. The <span class="monospaced">hw_device_t</span> structure will be extended to export <span class="monospaced">vkGetGlobalExtensionProperties</span>, <span class="monospaced">vkCreateInstance</span>, and <span class="monospaced">vkGetInstanceProcAddr</span> functions. The loader will find all other <span class="monospaced">VkInstance</span>, <span class="monospaced">VkPhysicalDevice</span>, and <span class="monospaced">vkGetDeviceProcAddr</span> functions by calling <span class="monospaced">vkGetInstanceProcAddr</span>.</p></div>
+</div>
+<div class="sect2">
+<h3 id="_layer_discovery_and_loading">1.2. Layer Discovery and Loading</h3>
+<div class="paragraph"><p>Android&#8217;s security model and policies differ significantly from other platforms. In particular, Android does not allow loading external code into a non-debuggable process on production (non-rooted) devices, nor does it allow external code to inspect or control the process&#8217;s memory/state/etc. This includes a prohibition on saving core dumps, API traces, etc. to disk for later inspection. So only layers delivered as part of the application will be enabled on production devices, and drivers must also not provide functionality that violates these policies.</p></div>
+<div class="paragraph"><p>There are three major use cases for layers:</p></div>
+<div class="olist arabic"><ol class="arabic">
+<li>
+<p>
+Development-time layers: validation layers, shims for tracing/profiling/debugging tools, etc. These shouldn&#8217;t be installed on the system image of production devices: they would be a waste of space for most users, and they should be updateable without requiring a system update. A developer wishing to use one of these during development has the ability to modify their application package (e.g. adding a file to their native libraries directory). IHV and OEM engineers who are trying to diagnose failures in shipping, unmodifiable apps are assumed to have access to non-production (rooted) builds of the system image.
+</p>
+</li>
+<li>
+<p>
+Utility layers, such as a layer that implements a heap for device memory. These layers will almost always expose extensions. Developers choose which layers, and which versions of those layers, to use in their application; different applications that use the same layer may still use different versions. Developers will choose which of these layers to ship in their application package.
+</p>
+</li>
+<li>
+<p>
+Injected layers, like framerate, social network, or game launcher overlays, which are provided by the user or some other application without the application&#8217;s knowledge or consent. These violate Android&#8217;s security policies and will not be supported.
+</p>
+</li>
+</ol></div>
+<div class="paragraph"><p>In the normal state the loader will only search in the application&#8217;s native library directory for layers; details are TBD but it will probably just try to load any library with a name matching a particular pattern(e.g. <span class="monospaced">libvklayer_foo.so</span>). It will probably not need a separate manifest file; the developer deliberately included these layers, so the reasons to avoid loading libraries before enabling them don&#8217;t apply.</p></div>
+<div class="paragraph"><p>On debuggable devices (<span class="monospaced">ro.debuggable</span> property exists and is non-zero, generally rooted or engineering builds) or debuggable processes (<span class="monospaced">prctl(PR_GET_DUMPABLE)==1</span>, based on the application&#8217;s manifest), the loader may also search an adb-writeable location on /data for layers. It&#8217;s not clear whether this is useful; in all the cases it could be used, the layer could be just as easily be put in the application&#8217;s native library directory.</p></div>
+<div class="paragraph"><p>Finally, the loader may include a built-in validation layer that it will enable based on settings in the Developer Options menu, which would send validation errors or warnings to the system log. Drivers may be able to emit additional hardware-specific errors/warnings through this mechanism. This layer would not be enumerated through the API. This is intended to allow cooperative end-users to collect extra information about failures from unmodified applications on unmodified devices to aid triage/diagnosis of difficult-to-reproduce problems. The functionality would be intentionally limited to minimize security and privacy risk.</p></div>
+<div class="paragraph"><p>Our goal is to allow layers to be ported with only build-environment changes between Android and other platforms. This means the interface between layers and the loader must match the interface used by the LunarG loader. Currently, the LunarG interface has a few deficiencies and is largely unspecified. We intend to work with LunarG to correct as many deficiencies as we can and to specify the interface in detail so that layers can be implemented without referring to the loader source code.</p></div>

The <span class="monospaced">VkSwapchain</span> object and all interaction with <span class="monospaced">ANativeWindow</span> will be handled by the platform and not exposed to drivers. The WSI implementation will rely on a few private interfaces to the driver for this implementation. These will be loaded through the driver&#8217;s <span class="monospaced">vkGetDeviceProcAddr</span> functions, after passing through any enabled layers.</p></div>

+objects become signalled when the underlying native fence signals; if the
+native fence has already signalled, then the semaphore will be in the signalled
+state when this function returns. The driver takes ownership of the fence fd
+and is responsible for closing it when no longer needed. It must do so even if
+neither a semaphore or fence object is provided, or even if

Effects are similar to <span class="monospaced">vkQueueSignalSemaphore</span>, except with a native fence instead of a semaphore. The native fence must: not signal until the <span class="monospaced">waitSemaphoreCount</span> semaphores in <span class="monospaced">pWaitSemaphores</span> have signaled. Unlike <span class="monospaced">vkQueueSignalSemaphore</span>, however, this call creates and returns the synchronization object that will be signalled rather than having it provided as input. If the queue is already idle when this function is called, it is allowed but not required to set <span class="monospaced">*pNativeFenceFd</span> to -1. The file descriptor returned in <span class="monospaced">*pNativeFenceFd</span> is owned and will be closed by the caller. Many drivers will be able to ignore the <span class="monospaced">image</span> parameter, but some may need to prepare CPU-side data structures associated with a gralloc buffer for use by external image consumers. Preparing buffer contents for use by external consumers should have been done asynchronously as part of transitioning the image to <span class="monospaced">VK_IMAGE_LAYOUT_PRESENT_SRC_KHR</span>.</p></div>

+// bad, of course. Representing sets of extensions (requested, supported, etc.)
+// as a bitset isn't necessarily bad, if the mapping from extension to bit were
+// dynamic. Need to rethink this completely when there's a little more time.
+
+// TODO(jessehall): This file currently builds up global data structures as it
+// loads, and never cleans them up. This means we're doing heap allocations
+// without going through an app-provided allocator, but worse, we'll leak those
+// allocations if the loader is unloaded.
+//
+// We should allocate "enough" BSS space, and suballocate from there. Will
+// probably want to intern strings, etc., and will need some custom/manual data
+// structures.
+
+// TODO(jessehall): Currently we have separate lists for instance and device
+// layers. Most layers are both; we should use one entry for each layer name,
+// with a mask saying what kind(s) it is.

+frameworks/native/vulkan/patches
+================================
+Each subdirectory corresponds to a sequence of patches. These are
+"virtual branches": we only have one shared branch, so these let us
+share experimental or auxiliary changes without disturbing the main
+branch.
+
+To apply:
+$ cd <somewhere in target git repo>
+$ git am $VULKAN_PATCHES/$PATCH_DIR/*
+
+
+frameworks_base-apk_library_dir
+-------------------------------
+This branch is for $TOP/frameworks/base. It modifies the framework to
+inform the Vulkan loader, during activity startup, where the
+activity's native library directory. The loader will search this
+directory for layer libraries. Without this change, layers will only
+be loaded from a global location under /data.
+
+
+build-install_libvulkan
+-----------------------
+This branch is for $TOP/build. It adds libvulkan.so to the base
+PRODUCT_PACKAGES variable, so it will be built and installed on the system
+partition by default.
