2013-11-26gbm/dri: hide extension loader symbolsMaarten Lankhorst1-2/+2
They should not be exposed. Cc: "10.0" <> (cherry picked from commit 5455c818b558cdc618441988434eb2755cd98b67)
2013-11-15gbm: Add support for __DRIimage based getBuffers when availableKristian Høgsberg2-2/+34
This lets us allocate color buffers as __DRIimages and pass them into the driver instead of having to create a __DRIbuffer with the flink that requires. With this patch, we can now run gbm on render-nodes. A render-node is a drm device that doesn't support modesetting and all the legacy DRI ioctls. flink is also not supported, but now that gbm doesn't need flink, we can run piglit on head-less gbm or head-less GPGPU.

We can now add GBM support for the 10 bit/channel formats which lets us create a gbm surface that we can use with KMS for display hardware that support the format. Signed-off-by: Kristian Høgsberg <>
2013-10-11wayland: Don't rely on static variable for identifying wl_drm buffersKristian Høgsberg2-1/+6
Now that libEGL has been fixed to not leak all kinds of symbols, gbm links to its own copy of the libwayland-drm.a helper library. That means we can't rely on comparing the addresses of a static vtable symbol in that library to determine if a wl_buffer is a wl_drm_buffer. Instead, we move the vtable into the wl_drm struct and use that for comparing. Cc: 9.2 <>
2013-08-12gbm: Link to libwayland-drm if Wayland EGL platform is enabledArmin K1-1/+2
We were relying on libEGL to pull in libwayland-client symbols, but with commit 2c2e64edaba0f6aeb181ca5b51eb8dea8e9b39f9 cleaned up the symbol leak.
2013-08-07egl: Update to Wayland 1.2 server APIAnder Conselvan de Oliveira1-2/+3
Since Wayland 1.2, struct wl_buffer and a few functions are deprecated. References to wl_buffer are replaced with wl_resource and some getter functions and calls to deprecated functions are replaced with the proper new API. The latter changes are related to resource versioning. Signed-off-by: Ander Conselvan de Oliveira <>

2012-10-21gbm: Use the kms dumb ioctls for cursor instead of libkmsKristian Høgsberg2-48/+77
We need to create bos suitable for cursor usage that we can map and write data into. The kms dumb ioctls is all we need for this, so drop the dependency on libkms.

2012-08-31dri: Rework planar image interfaceJakob Bornecrantz1-20/+13
As discussed with Kristian on #wayland. Pushes the decision of components into the dri driver giving it greater freedom to allow t to implement YUV samplers in hardware, and which mode to use. This interface will also allow drivers like SVGA to implement YUV surfaces without the need to sub-allocate and instead send 3 seperate buffers for each channel, currently not implemented. I have tested these changes on Gallium Svga. Scott tested them on both intel and Gallium Radeon. Kristan and Pekka tested them on intel. v2: Fix typo in dri2_from_planar. v3: Merge in intel changes.

2012-08-26gbm: Use libkms to replace DRI cursor imagesJakob Bornecrantz3-12/+64
Uses libkms instead of dri image cursor. Since this is the only user of the DRI cursor and write interface we can remove cursor surfaces entirely from the DRI interface and as a consequence also from the Gallium interface as well. Tho to make everybody happy with this it would probably should add a kms_bo_write function, but that is probably wise in anyways. The only downside is that it adds a dependancy on libkms, this could how ever be replaced with the dumb_bo drm ioctl interface. Tested-by: Scott Moreau <> Signed-off-by: Jakob Bornecrantz <>

2012-07-16gbm: Rename gbm_bo_get_pitch to gbm_bo_get_strideKristian Høgsberg4-7/+7
We use pitch for 'pixels per row' and stride for 'bytes per row' pretty consistently in mesa and most other places, so rename the gbm API.
2012-07-16gbm: Add new gbm_bo_import entry pointKristian Høgsberg5-48/+95
This generalizes and replaces gbm_bo_create_for_egl_image. gbm_bo_import will create a gbm_bo from either an EGLImage or a struct wl_buffer.
2012-05-03gbm: Add gbm_bo_write entry pointKristian Høgsberg4-0/+47
This new gbm entry point allows writing data into a gbm bo. The bo has to be created with the GBM_BO_USE_WRITE flag, and it's only required to work for GBM_BO_USE_CURSOR_64X64 bos. The gbm API is designed to be the glue layer between EGL and KMS, but there was never a mechanism initialize a buffer suitable for use with KMS hw cursors. The hw cursor bo is typically not compatible with anything EGL can render to, and thus there's no way to get data into such a bo. gbm_bo_write() fills that gap while staying out of the efficient cpu->gpu pixel transfer business.

2012-03-28gbm: Create hooks for dri2_loader_extension in dri backendAnder Conselvan de Oliveira2-2/+66
Pass a dri2_loader extension to the dri driver when gbm creates the dri screen. The implementation jumps through pointers in the gbm device so that an EGL on GBM implementation can provide the real implementations.
2012-03-28gbm: Add gbm_surface interfaceAnder Conselvan de Oliveira5-5/+186
The idea here is to be able to create an egl window surface from a gbm_surface. This avoids the need for the surfaceless extension and lets the EGL platform handle buffer allocation, while keeping the user in charge of somehow presenting the buffers (using kms page flipping, for example). gbm_surface_lock_front_buffer() locks a surface's front buffer and returns a gbm bo representing it. This bo should later be returned to the gbm surface using gbm_surface_release_buffer().

2012-03-19shared-glapi: Convert to automakeKristian Høgsberg1-2/+2
This fixes a build problem where EGL links to, which encodes a relative path to it's dependency. The relative path breaks when the linker tries to resolve it from src/egl/main instead of src/gbm. Typically we silently fall back to the system, which is wrong and breaks when there isn't one. Morale of the story: don't mix mklib and libtool.
2012-03-07gbm_dri: Fix DRIimage lookup callbackBenjamin Franzke1-2/+2
That is by making the dri extension variables static in gbm_dri.c. The image_lookup_extension is provided by egl_dri2 when using x11 or wayland platforms, when using the drm platform, gbm_dri has a wrapper for it. Both use the same variables name image_lookup_extension. Since -fvisibility=hidden was (probably by mistake) removed when converting to automake, the "image_lookup_extension" symbol from egl_dri2.c became exported in, so "image_lookup_extension" from gbm_dri.c was ignored. This resulted in calling incorrect callbacks. We cant make the image_lookup_extension static in egl_dri2.c right now, since its used across multiple files. Bugzilla: Reviewed-by: Kristian Høgsberg <>
2012-02-22gbm: track buffer format through DRI driversJesse Barnes4-5/+164
GBM needs the buffer format in order to communicate with DRM and clients for things like scanout. So track the DRI format requested in the various back ends and use it to return the DRI format back to GBM when requested. GBM will then map this into the GBM surface type (which is in turn based on the DRM fb format list). Signed-off-by: Jesse Barnes <>
