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.
Avoids repeating the common bits between dma_tex_features and
dma_tex_ycbcr_features, and we will need just the YCbCr-related
flags for shm YCbCr support soon.
These features are required for shm only: the TRANSFER stuff is
for texture upload. We don't need these for DMA-BUFs. Make this
clearer by changing the name.
Also re-order the definitions to group all texture-related features
together.
Based on five calls:
wlr_render_timer_create - creates a timer which can be reused across
frames on the same renderer
wlr_renderer_begin_buffer_pass - now takes a timer so that backends can
record when the rendering starts and finishes
wlr_render_timer_get_time - should be called as late as possible so that
queries can make their way back from the GPU
wlr_render_timer_destroy - self-explanatory
The timer is exposed as an opaque `struct wlr_render_timer` so that
backends can store whatever they want in there.
The Vulkan spec states:
> For the purposes of range expansion and Y′CBCR model conversion,
> the R and B components contain color difference (chroma) values
> and the G component contains luma.
The equations below that sentence also help understand the mapping.
We don't actually need the REPEAT mode, and this makes things more
consistent with the YCbCr sampler (which requires CLAMP_TO_EDGE for
spec compliance).
Also drop borderColor which is unused for this mode.
Fixes the following validation error:
[ VUID-VkImageViewCreateInfo-pNext-01970 ] Object 0: handle = 0x62e00003c400, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0xf378e14b | vkCreateImageView(): If there is a VkSamplerYcbcrConversion, the imageView must be created with the identity swizzle.
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.
Address Sanitizer reported two memory leaks because of
fmt not being freed in wlr_drm_format_set_copy.
This commit fixes the memory leak by removing the
allocation to the heap. The struct is allocated to the
stack anyway.
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.
This fixes the following validation errors when shutting down Sway:

Remove debug logs when a texture is created, since this happens
pretty often. Use drmGetFormatName() and drmGetFormatModifierName()
to log DRM formats and modifiers.
This ensures that the pool sizes grow exponentially, making the number
of pools needed logarithmic in the number of descriptors, instead of
linear. Since the first pool's size is 256, this change only has an
effect when the compositor creates a large number of textures.
Goals:
- Extensibility: we need to be able to add new params to the calls
to render a texture/rect. For instance we'll need to add fences to
the render texture operation for explicit sync purposes.
- No implicit state: no more bind_buffer, begin, end.
- No matrices: these hurt Pixman and we don't need them.
- Clip regions for optimized damage repainting.

Setting the GLESv2 parameter GL_PACK_ALIGNMENT to 1 ensures that the
stride of the glReadPixels output matches the value computed in
`pack_stride`. Since the default value of GL_PACK_ALIGNMENT is 4, this
does not make a difference under normal use; but without this patch
the stride can be incorrect; for example, with RGB565 buffers and
screenshots of regions with odd width.
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.
Reverts commit c73e20628a.
This caused a regression in the GLES2 renderer because `egl->exts.EXT_device_drm` is set in
`egl_init_display()`, which is invoked after `get_egl_device_from_drm_fd()`. So the function will
always return `EGL_NO_DEVICE_EXT`.
Some formats like YUV are only supported by Mesa for sampling, not
for rendering. However we always unconditionally added the INVALID
modifier to the list of render formats.
Check whether all modifiers are external-only, in that case, don't
add INVALID to the list of render formats.
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.
pre_cb was an alias for stage_cb->vk. Let's just use a single
variable instead.
Additionally, early return when vulkan_record_stage_cb() fails.
We were crashing in vkCmdPipelineBarrier() if that happened.
Skip clears with an empty scissor.
Fixes the following validation error:
00:00:09.734 [wlr] [render/vulkan/vulkan.c:61] Validation Error: [ VUID-vkCmdClearAttachments-rect-02682 ] Object 0: handle = 0x62600001b100, type = VK_OBJECT_TYPE_COMMAND_BUFFER; | MessageID = 0xadbd476f | CmdClearAttachments(): pRects[0].rect.extent.width is zero. The Vulkan spec states: The rect member of each element of pRects must have an extent.width greater than 0 (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkCmdClearAttachments-rect-02682) (VUID-vkCmdClearAttachments-rect-02682)
We were filling VkTimelineSemaphoreSubmitInfoKHR.pSignalSemaphoreValues,
but we were missing VkSubmitInfo.pSignalSemaphores.
This was causing VkTimelineSemaphoreSubmitInfoKHR.pSignalSemaphoreValues
to be ignored. By chance, the render command buffer was using the
next timeline point, so we were waiting for that instead.
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.
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.
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.
Let's just forward-declare struct wlr_backend instead.
We need to fixup the Vulkan renderer: it needs makedev(), which
got included by chance via <wlr/backend.h> → <wlr/backend/session.h>
→ <libudev.h>.
We'll use this function from wlr_shm too.
Add some assertions, use int32_t (since the wire protocol uses that,
and we don't want to use 16-bit integers on exotic systems) and
switch the stride check to be overflow-safe.
Call glGetGraphicsResetStatusKHR in wlr_renderer_begin to figure
out when a GPU reset occurs. Destroy the renderer when this
happens (the OpenGL context is defunct).
Allow to get whether has alpha channel of the VkImage, it can help an
optimization to disable blending when the texture doesn't have alpha.
Because the VkFormat isn't enough because it's always set to
VK_FORMAT_B8G8R8A8_SRGB or VK_FORMAT_R8G8B8A8_SRGB.
`modifiers` and `external_only` are never initialized, and free'd later. This
commit explicitly initializes them to NULL to prevent segfaults on `free()`
