strcmp() returns a signed integer.

This makes grepping much easier.
|
|
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.

Instead of returning a primary node from wlr_renderer_get_drm_fd(),
prefer to return a render node if any.

Past that point the wlr_allocator is gone and the listeners are
invalidated.
|
|
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 c73e20628ad3cf8a38fc1cebd061a49da8708394.
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`.
|
|
Without EGL_EXT_device_drm, eglQueryDeviceStringEXT(EGL_DRM_DEVICE_FILE_EXT) further below is invalid.

The spec [1] says that the maximum value for a mediump float
is at least 2¹⁴ in section 4.5.2. However, when using a 4k
resolution texture coordinates will exceed this value. This causes
issues on drivers which implement mediump as a 16-bit [2].
Switch to highp. There's a twist: on GLES2, support for highp is
optional. So we need to guard it with cute GL_FRAGMENT_PRECISION_HIGH
ifdefs.

Doesn't matter a lot, but let's try to be consistent with the
GL headers.
|
|
Fail with a clearer error when the requested size is too large.
Without this, we allocate a buffer with a size smaller than what
was requested.

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.

EGL_EXT_image_dma_buf_import_modifiers [1] uses EGLint to carry
formats. We were casting it to int (which may not be the same
width) and uint32_t (which may change the value).
Instead, use EGLint everywhere.

We sometimes used HAS_, sometimes polluted the LIBINPUT_ namespace,
etc.

Removes a project argument.

Use early returns to remove the !renderer checks.

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.

We always have a stage_cb at this point.
|
|
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:

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.
|
|
Move it down, right before it's used.

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.

|
|
Use a more appropriate message on
vkGetPhysicalDeviceImageFormatProperties2() error.

DRM_FORMAT_INVALID is zero. Let's just omit the fields to make the
table more readable.
