A spa_node has callback both on the main and data thread, which can
modify the internal state of vulkan_blit_state. Especially critical are
functions, which might drop buffers currently in use. To mitigate this
a read-write lock is used. The data thread shall try to aquire a read
lock before accessing the buffers, while the main thread has to aquire
exclusive access via a write lock before modifying the buffers.
We need a database of pixel format properties to remove hardcoded magic
numbers. This commit creates a simple function to query the bytes per
pixel for common RGBA formats.
This should be promoted to or superseeded by a common spa namespaced
version.
This splots the format enumeration into a helper for dsp and raw pod
creation and a common function for the compute filters.
Counting formats with modifiers will be usefull to announce dsp and
raw formats from the same node.
No functional changes.
Validation of properties is moved from the import and allocation
functions into a separate function. This allows later separation of
modifier informations from the base struct.
This extension is required for the aquire and release barriers
to transfer the buffer ownership from and two an external queue.
This removes a warning from the validation layers.
If the modifier for a format is not fixated yet, we will use vulkan to
fixate a modifier, update the parsed format, change the EnumFormats mask
and exit early. This triggers a new enum_params with EnumFormats and a
new set_param for Format.
This commit add helpers to create and to import a DmaBuf via the
external_dmabuf_info struct.
The import path is based on the image creation of wlroots and the create path is
inspired by the wlroots vulkan allocator MR.
vulkan_wait_idle waits until the device is idle and all referenced
objects can be destroyed.
vulkan_wait_fence waits until a fence is triggered by a finished
queueSubmit.
vulkan: wait on fence
This commit should just shuffle code around with no functional changes.
The goal is to ease development of simple vulkan nodes by providing
generic helpers.
