Add -Wextra flag and fix warnings With the addition of the -Wextra flag, additional compiler warnings are enabled, which help identify potential issues in the code. However, enabling -Wextra caused compilation failures due to the -Werror flag, which treats warnings as errors. This commit enables -Wextra and addresses all the warnings produced, ensuring the code compiles successfully while maintaining higher code quality standards.

Initial sources for the vulkan-wsi-layer project This commit adds the initial sources for the vulkan-wsi-layer project: a Vulkan layer which implements some of the Vulkan window system integration extensions such as VK_KHR_swapchain. The layer is designed to be GPU vendor agnostic when used as part of the Vulkan ICD/loader architecture. The project currently implements support for VK_EXT_headless_surface and its dependencies. We hope to extend support for further platforms such as Wayland and direct-to-display rendering in the future. This initial commit collects contributions from different individuals employed by Arm. More information on the project (building instructions, how to contribute, etc.) can be found on the README.md file at the top of the project tree.

Adds initial support for VK_KHR_wayland_surface. Very basic Wayland support is implemented by importing memory with VK_EXT_image_drm_format_modifiers. The current implementation requires an external system memory allocator. An API for this allocator is defined in util/wsialloc/wsialloc.h and an implementation using the ION memory allocator is included. Outstanding issues: * This is an initial prototype for Wayland support and has many outstanding TODOs which need addressing to properly use the Wayland protocol. * Using ICD Exported memory instead of a system allocator is not implemented. Wayland support is still experimental and outstanding issues will be fixed in future commits.

Disable the FIFO present thread implementation on Wayland by default The FIFO implementation in the Wayland backend that uses the presentation thread is not technically Vulkan conformant. This commit enables a true FIFO implementation that is conformant to the Vulkan spec by blocking in the vkQueuePresent path. On Wayland this is achieved by having the main thread wait for the frame_done event to be sent by the compositor. This was already used in FIFO before but previously it would be the presentation thread that would block. This implementation is now used by default. The downside of this approach is that it has a significant performance impact due to blocking the main thread. Users wishing to continue using the presentation thread implementation to achieve better performance can still do so through a new build option `ENABLE_WAYLAND_FIFO_PRESENTATION_THREAD`. The README has also been updated to document the FIFO shortcomings. Signed-off-by: Dennis Tsiang <dennis.tsiang@arm.com> Change-Id: I8674f9ea330a45f97d32024f97057ffc25c76c7a

Implement objects associated with VkSurface Defines an abstract wsi::surface object to be implemented by each WSI backend. This object is then associated with the corresponding VkSurface object in the instance specific data. To keep track of these objects the layer now intercepts vkDestroySurfaceKHR, while specific surface creation entrypoints are intercepted by individual WSI backends. In addition this change should allow for fixing incompatibility issues with layers that wrap VkSurface which breaks casting to the Loader's ICD VkSurface type. Make greater use of util::unique_ptr and allow for such pointers to be constructable when casting derived types.

This will be removed when the swapchain images will be created from the swapchain image creator. Moves the definition of drm_format_pair to drm_utils.

wsi/wayland/present_wait_wayland.cpp
Decouple swapchain images and their memory from swapchain class Decouples the swapchain images and their memory binder/allocator logic into separate classes. This allows us to reduce code duplication across different backends that use the same type of allocation logic and also allows us to make use of RAII to release the resources for swapchain images. The swapchain_base and other swapchain classes have been refactored to handle the new swapchain images. The patch makes the following adjustments: * Introduces a new swapchain_image class that holds all swapchain image resources * Introduces a swapchain image factory class that constructs swapchain images * Introduces a Vulkan image handle class that is responsible for constructing VkImage handles * Introduces a new interface that describes how swapchain backing memory is being allocated * As part of this backing memory interface, introduces device and external (wsialloc) backing memory classes * Introduces a new interface that holds swapchain image data like wl_buffers * Refactors lots of swapchain image parts out of the base swapchain class and moves it into the respective backends to simplify the swapchain classes.

Disable the FIFO present thread implementation on Wayland by default The FIFO implementation in the Wayland backend that uses the presentation thread is not technically Vulkan conformant. This commit enables a true FIFO implementation that is conformant to the Vulkan spec by blocking in the vkQueuePresent path. On Wayland this is achieved by having the main thread wait for the frame_done event to be sent by the compositor. This was already used in FIFO before but previously it would be the presentation thread that would block. This implementation is now used by default. The downside of this approach is that it has a significant performance impact due to blocking the main thread. Users wishing to continue using the presentation thread implementation to achieve better performance can still do so through a new build option `ENABLE_WAYLAND_FIFO_PRESENTATION_THREAD`. The README has also been updated to document the FIFO shortcomings. Signed-off-by: Dennis Tsiang <dennis.tsiang@arm.com> Change-Id: I8674f9ea330a45f97d32024f97057ffc25c76c7a

This allows us to reduce code duplication across different backends that use the same type of allocation logic and also allows us to make use of RAII to release the resources for swapchain images. The swapchain_base and other swapchain classes have been refactored to handle the new swapchain images. The patch makes the following adjustments: * Introduces a new swapchain_image class that holds all swapchain image resources * Introduces a swapchain image factory class that constructs swapchain images * Introduces a Vulkan image handle class that is responsible for constructing VkImage handles * Introduces a new interface that describes how swapchain backing memory is being allocated * As part of this backing memory interface, introduces device and external (wsialloc) backing memory classes * Introduces a new interface that holds swapchain image data like wl_buffers * Refactors lots of swapchain image parts out of the base swapchain class and moves it into the respective backends to simplify the swapchain classes.

The layer is designed to be GPU vendor agnostic when used as part of the Vulkan ICD/loader architecture. The project currently implements support for VK_EXT_headless_surface and its dependencies. We hope to extend support for further platforms such as Wayland and direct-to-display rendering in the future. This initial commit collects contributions from different individuals employed by Arm.

Support timestamp calibration for present stage local time domains In this change, the support for present stage local time doimain is enabled. The Vulkan entry-points vkGetCalibratedTimestampsEXT and vkGetCalibratedTimestampsKHR are introduced. These entry-points are intercepted for the structure VkSwapchainCalibratedTimestampInfoEXT to calibrate any stage local time domains. Internally, the stage local time domains are mapped to VK time domains with an offset. On intercepting the APIs when the structure VkSwapchainCalibratedTimestampInfoEXT is available, timestamps are internally queried based on VK time domain from the driver and are then converted to the corresponding stage local timestamps using the internally maintained offset for the time domain.

We hope to extend support for further platforms such as Wayland and direct-to-display rendering in the future. This initial commit collects contributions from different individuals employed by Arm. More information on the project (building instructions, how to contribute, etc.) can be found on the README.md file at the top of the project tree.

util/timed_semaphore.cpp
Implement a vector utility that uses a custom allocator Add util::vector to provide functionality similar to std::vector, i.e. growable arrays. util::vector does its allocations via a custom allocator provided via VkAllocationCallbacks and provides methods to check whether the allocation fails, e.g. try_push_back() returns false when the allocation fails and replaces std::vector's push_back() method that would rather raise an exception to report an allocation failure. Note that this commit switches on exceptions in the layer by removing the flag -fno-exceptions. util::vector is also used to store swapchain images.

Add support for VK_EXT_image_compression_control_swapchain Implement support for VK_EXT_image_compression_control_swapchain for both the Wayland and the headless windowing systems. The extension can be conditionally enabled through the new build option BUILD_WSI_IMAGE_COMPRESSION_CONTROL_SWAPCHAIN. Compiling with this option enabled requires recent Vulkan headers (1.3.213) Note also that support in the layer is enabled conditionally to the ICD supporting VK_EXT_image_compression_control. Update the WSIALLOC interface to version 2 and add support to prefer selection of a format with the highest fixed rate compression from the formats provided. This is used to pick a fixed rate compression when VK_IMAGE_COMPRESSION_FIXED_RATE_EXPLICIT_EXT is specified during swapchain creation.

Decouple creation, allocation and binding of images from Wayland backend A lot of the steps involved in creating a VkImage, allocating backing memory, and binding the VkImage to the memory do not rely specifically on Wayland features and could be common to other WSI backends. This commit attempts to decouple the create_and_bind_swapchain_image() function in the wsi/wayland/swapchain.cpp from Wayland and wsialloc specific parts, and instead move the independent parts related to external memory management to a new external_memory class. This will allow the independent code to be re-used in future WSI backends. Signed-off-by: Dennis Tsiang <dennis.tsiang@arm.com> Change-Id: I8c13ccbbfaef0d345fcd06192e6de484dd53645f

Introduce an extensions abstraction in the layer In this change, an abstraction layer is added to the swapchain extensions. The extensions present_timing, present_id, image_compression_control, frame_boundary, and swapchain_maintenance1 are moved to the new extensions abstraction framework. Additionally, the compression control extension has been formalized in the layer as it is part of Vulkan spec so compression control guards have been removed.

Enables the present wait extension by default - experimental flag is no longer needed. Fixes the following issues: * For Wayland backend, populates the presentation feedback listener with all callbacks as it is considered a fault by the protocol to not implement those * For Wayland backend presentation feedback listener, forwards the feedback_discarded event to present ID as there could be situations where previously submitted buffers are discarded, such as when swapchains are using the MAILBOX presentation mode. * For all swapchains, communicate critical errors back to present wait extension as otherwise, all callers waiting that are waiting on present to be delivered in vkWaitForPresentKHR call will never exit. * Expanded the implementation in vkWaitForPresentKHR to be able to return critical swapchain errors if they have occured during the wait time. * Fix issues in present ID where infinite waits could result in the vkWaitForPresentKHR call returning immediately due to UINT64_MAX timeout resulting in overflowing the system clock used in std::condition_variable Change-Id: I1e475c3073c05394db259657eae1da21764a5a5c Signed-off-by: Normunds Rieksts <normunds.rieksts@arm.com> Signed-off-by: Alex Bates <alex.bates@arm.com>

Decouple swapchain images and their memory from swapchain class Decouples the swapchain images and their memory binder/allocator logic into separate classes. This allows us to reduce code duplication across different backends that use the same type of allocation logic and also allows us to make use of RAII to release the resources for swapchain images. The swapchain_base and other swapchain classes have been refactored to handle the new swapchain images. The patch makes the following adjustments: * Introduces a new swapchain_image class that holds all swapchain image resources * Introduces a swapchain image factory class that constructs swapchain images * Introduces a Vulkan image handle class that is responsible for constructing VkImage handles * Introduces a new interface that describes how swapchain backing memory is being allocated * As part of this backing memory interface, introduces device and external (wsialloc) backing memory classes * Introduces a new interface that holds swapchain image data like wl_buffers * Refactors lots of swapchain image parts out of the base swapchain class and moves it into the respective backends to simplify the swapchain classes.
