Why track the alpha here when we can already get that information
elsewhere?
|
|
This was used by the legacy rendering API. Since begin()/end()
only need to set current_render_buffer and nothing else, we can
drop all of these bits.
|
|
All built-in renderers now implement the new API.
|
|
This commit only applies to the render pass API.
|
|
|
|
The flags passed to vkCreateImage() must match the flags used when
querying formats. Make this clearer by using the same variable.
|
|
|
|
Now that we are dynamically creating pipeline layouts, we need separate
texture views for each pipeline layout we choose to use with a texture.
|
|
These will happen lazily when pipelines get created.
|
|
This will become necessary when we switch away from scissoring. For the
time being, this cleans things up a bit and allows for a trivial
blending implementation for textures when that comes.
|
|
|
|
If we ever wanted to handle dynamic state that requires new pipelines
such as using different texture filters those can be added here with more
ease.

Will make it easier to add more pipeline layouts for other YCbCr
formats.
|
|
This will make it easier to create one pipeline layout (plus related
objects) per YCbCr format.
|
|
Some formats like sub-sampled YCbCr use a block of bytes to
store the color values for more than one pixel. Update our format
table to be able to handle such formats.

This is implemented by a two-subpass rendering scheme; the first
subpass draws (and blends) onto a linear R16G16B16A16_SFLOAT buffer,
while the second subpass performs linear->srgb conversion, writing
onto the actual output buffer.
|
|
Now it takes a reference to a destination format
|

|
This simplifies the vkQueueSubmit call, removing the need to pass
timeline semaphore point values as separate arrays.
|
|
|
|
This logic is used twice.
|
|
Add a render pass implementation which leverages the legacy
rendering API. This is helpful during the migration.
|
|
This makes grepping much easier.
|
|
Instead of returning a primary node from wlr_renderer_get_drm_fd(),
prefer to return a render node if any.
|
|
We've had this struct for a while. It'd be useful for compositors
if they want to manage the swap chains themselves instead of being
forced to use wlr_output's. Some compositors might also want to use
a swapchain without an output.
|
|
The Vulkan spec doesn't guarantee that the driver will wait for
implicitly synchronized client buffers before texturing from them.
radv happens to perform the wait, but anv doesn't.
Fix this by extracting implicit fences from DMA-BUFs, importing
them into Vulkan as a VkSemaphore objects, and make the render pass
wait on these VkSemaphores.
|
|
|
|
struct wlr_vk_format_props contains a mix of properties for shm
and dmabuf, and it's not immediately clear which fields are for
which kind of buffer. Use a nested struct to group the fields.
|
|
|
|
|
|
"format" is already in the name, no need to repeat ourselves.
`format->vk_format` sounds a bit redundant.
|
|
Right now the Vulkan renderer blocks until the frame is complete
after rendering. This is necessary because Vulkan doesn't
interoperate well with implicit sync we use everywhere else.
Use the new kernel API to import a sync_file into a DMA-BUF to
avoid blocking.

We need to wait for the pending command buffer to complete before
re-using stage buffers. Otherwise we'll overwrite the stage buffer
with new contents before the texture is fully uploaded.
|
|
We need to wait for any pending command buffer to complete before
we're able to fully destroy a struct wlr_vk_texture: the Vulkan
spec requires the VkDescriptorSet to be kept alive.
So far we've done this in vulkan_end(), after blocking until the
command buffer completes. We'll soon stop blocking, so move this
logic in get_command_buffer(), where we check which commands buffers
have completed in a non-blocking fashion.
|
|
export_imported is never used, and dmabuf_flags is already checked
in query_modifier_support().
|
|
vkCmdCopyBufferToImage requires that the buffer offset be a multiple
of the texel block size, which for single plane uncompressed formats
is the same as the number of bytes per pixel. This commit adds an
alignment parameter to vulkan_get_stage_span which ensures that the
provided span (and the sequence of image copy operations derived which
use it) have this alignment.
|
|
Since this does not have a matching _SRGB-type vulkan format, add a
new shader variant/pipeline to perform the sRGB->linear texture
conversion.
