2021-11-25render/allocator: fallback to renderer DRM FD in autocreateSimon Ser
If the backend doesn't have a DRM FD, fallback to the renderer's. This accomodates for the situation where the headless backend hasn't picked a DRM FD in particular, but the renderer has picked one.
2021-11-25render: pick DRM FD in autocreateSimon Ser
If the backend hasn't picked a DRM FD but supports DMA-BUF, pick an arbitrary render node. This will allow removing the DRM device selection logic from the headless backend.

I additionally considered using >> 1 instead of * 0.5, but AMD has dedicated modifiers to merge a * 0.5, * 2.0, etc in a single instruction.

2021-11-23render/vulkan: quiet glslangValidatorSimon Ser
This suppresses the output filename printed to stdout. Errors and warnings should still be printed to stderr as usual.
2021-11-17Improve wlr_drm_format documentationDemi Marie Obenour
A wlroots user can easily get confused and think that `cap` refers to wlroots buffer capabilities, not array capacity.
2021-11-17Remove support for DMA-BUF flagsSimon Ser
They are never used in practice, which makes all of our flag handling effectively dead code. Also, APIs such as KMS don't provide a good way to deal with the flags. Let's just fail the DMA-BUF import when clients provide flags.

2021-11-09render/allocator: make wlr_allocator part of the public APISimon Zeni
2021-11-02render: completely disable gles2 if requested but libEGL is foundJan Beich
For `required` to disable search the value needs to be of `feature` type. Checking `gles2` via `in` keyword returns a `bool` but `required: false` makes the dependency optional instead of disabled.

2021-10-19render/vulkan: check vulkan-headers dependencySimon Ser
There's no pkg-config file we can check for sadly, so check vulkan/vulkan.h as a fallback. Closes: https://github.com/swaywm/wlroots/issues/3272
2021-10-18render/vulkan: Use image view swizzles instead of shader hackJoshua Ashton
Signed-off-by: Joshua Ashton <joshua@froggi.es>
2021-10-18render/vulkan: add Vulkan renderernyorain
This new renderer is implemented with the existing wlr_renderer API (which is known to be sub-optimal for some operations). It's not used by default, but users can opt-in by setting WLR_RENDERER=vulkan. The renderer depends on VK_EXT_image_drm_format_modifier and VK_EXT_physical_device_drm.

2021-10-14render/allocator: use empty DRM lease to re-open nodeSimon Ser
This allows us to obtain a new DRM file description without relying on filesystem permissions.
2021-10-04render/allocator: use render node if available in reopen_drm_nodeSimon Ser
If we aren't trying to create a dumb buffer allocator, and if the DRM device has a render node (ie, not a split render/display SoC), then we can use the render node instead of the primary node. This should allow wlroots to run under seatd when the current user doesn't have the permission to open primary nodes (logind has a quirk to allow physically logged in users to open primary nodes).
2021-10-01Revert "render/drm_format_set: add wlr_drm_format_has"Simon Ser

2021-10-01render/drm_format_set: remove special LINEAR caseSimon Ser
This was used to make the intersection of INVALID and LINEAR result in LINEAR. We can now just require LINEAR to be in both lists.

2021-09-15types/buffer: make {begin,end}_data_ptr_access part of the public APISimon Zeni
2021-09-10buffer: add data_ptr access flagsSimon Ser
This allows callers to specify the operations they'll perform on the returned data pointer. The motivations for this are: - The upcoming Linux MAP_NOSIGBUS flag may only be usable on read-only mappings. - gbm_bo_map with GBM_BO_TRANSFER_READ hurts performance.
2021-09-03render/allocator/gbm: add log message for gbm_bo_get_fd_for_planeSimon Ser
Makes it easier to find out which branch is taken when debugging issues like [1]. [1]: https://github.com/swaywm/wlroots/issues/3156
2021-09-03render/allocator: use legacy authentication for primary nodesSimon Ser

2021-09-01render/allocator: re-open GBM FDSimon Ser
Using the same DRM file description for the DRM backend and for the GBM allocator will result in GEM handle ref'counting issues [1]. Re-open the DRM FD to fix these issues. [1]: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/110
2021-08-25render/egl: reopen DRM node for GBMSimon Ser
This will be necessary for the next patch, to avoid messing up BO handles shared between the GL implementation and the DRM backend.
2021-08-25Move allocator stuff into new directorySimon Ser
Add render/allocator/ and include/render/allocator/ to hold everything allocator-related.

Saves us from walking a list.
2021-08-03render/pixman/pixel_format: add more formatsSimon Ser
Add a bunch of new formats for Pixman: a few missing 32-bit ones, some 16-bit and 32-bit formats as well. Mostly based on a Weston patch [1]. [1]: https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/664
2021-08-03render/pixel_format: add more formats for PixmanSimon Ser
These will be added to Pixman in the next commit.
2021-07-30render/gles2: add a few 10-bit and FP16 formatsManuel Stoeckl
The half-float formats depend on GL_OES_texture_half_float_linear, not just the GL_OES_texture_half_float extension, because the latter does not include support for linear magni/minification filters. The new 2101010 and 16161616F formats are only available on little- endian builds, since their gl_types are larger than a byte and thus endianness dependent.
2021-07-30render/gles2: hide shm formats without GL supportManuel Stoeckl
This change introduces a new function to check whether the renderer has the needed GL extensions to read a given pixel format.

2021-07-29render/gles2: add support for some 24 and 16-bit formatsSimon Ser
On little-endian, we can enable pixel formats which don't use gl_type = GL_UNSIGNED_BYTE. See [1]. [1]: https://afrantzis.com/pixel-format-guide/

2021-07-27render/egl: initialize wlr_egl with EGL_PLATFORM_DEVICE_EXTSimon Zeni
Uses the EXT_device_query extension to get the EGL device matching the requested DRM file descriptor. If the extension is not supported or no device is found, the EGL device will be retrieved using GBM. Depends on the EGL_EXT_device_enumeration to get the list of EGL devices.
2021-07-27render/egl: fix typoyuiiio
2021-07-26render/egl: add support for EGL_EXT_device_drm_render_nodeSimon Ser
This EGL extension has been added in [1]. The upsides are: - We directly get a render node, instead of having to convert the primary node name to a render node name. - If EGL_DRM_RENDER_NODE_FILE_EXT returns NULL, that means there is no render node being used by the driver. [1]: https://github.com/KhronosGroup/EGL-Registry/pull/127
2021-07-23render/egl: set EGL_IMAGE_PRESERVED_KHRSimon Ser
Without setting this the EGL implementation is allowed to perform destructive actions on the buffer when imported: its contents become undefined. This is mostly a pedantic change, because Mesa processes the attrib and does absolutely nothing with it.
2021-07-22render/wlr_texture: put wlr_texture_from_buffer into the public APISimon Zeni
2021-07-22render: drop wlr_renderer_impl.init_wl_displaySimon Ser
Now that we have our own wl_drm implementation, there's no reason to provide custom renderer hooks to init a wl_display in the interface. We can just initialize the wl_display generically, depending on the renderer capabilities.
2021-07-12render/gles2: disable blending opportunisticallySimon Ser
We don't always need to enable blending: when the texture doesn't have alpha or when the color is opaque, we can disable it.
2021-07-12render/gles2: set has_alpha for DMA-BUFsSimon Ser
Use our internal pixel format table to figure out whether an imported DMA-BUF has alpha.
2021-07-12render/gles2: rename wlr_egl.exts to better match KhronosSimon Ser
Khronos refers to extensions with their namespace as a prefix in uppercase. Change our naming to align with Khronos conventions. This also makes grepping easier.
