Hi, This patch series contains necessary radeonsi changes in order to support OpenGL-OpenCL interop. This only covers buffer and texture sharing.
The changes can be summarized to: - write an image descriptor to amdgpu buffer metadata for OpenCL to use it - buffer map/unmap optimizations need to be aware of shared buffers - disable CMASK and DCC when needed - allow texture sharing with DCC enabled - get the PCI device location (group:bus:dev:func) for OpenCL to query it later Dependent gallium patches sent separately: - resource_from(get)_handle getting new flags - new PCI device location CAPs This radeonsi series and dependent gallium patches are required for being able to implement the already-proposed public Mesa interop API in st/dri, libGL, and libEGL. Descriptions of the patches: gallium/radeon: use a structure for passing tiling flags from/to winsys gallium/radeon: remove rcs parameter from radeon_winsys::buffer_set_tiling gallium/radeon: rename winsys buffer_get/set_tiling to buffer_get/set_metadata - Cleaning up the winsys API for setting tiling flags, no functional changes. winsys/amdgpu: allow drivers to set/get opaque metadata - Adding amdgpu metadata support to the winsys. gallium/radeon: move code initializing texture metadata to its own function gallium/radeon: clean up r600_texture_get_handle - Cleanups. gallium/radeon: set texture metadata only once - Starting to track which resources are shared. gallium/radeon: don't set texture metadata for buffers gallium/radeon: buffer valid range tracking only works with unshared buffers gallium/radeon: if we can't discard a whole resource, discard the range instead galilum/radeon: disallow reallocation of shared buffers - Support for shared buffers. gallium/radeon: check that handle usage doesn't change for a resource gallium/radeon: remember that texture_from_handle was called and its flags - More tracking of which resources are shared. gallium/radeon: disallow handle export for MSAA & depth textures gallium/radeon: don't use fast color clear if sharing doesn't allow it gallium/radeon: eliminate fast color clear before sharing gallium/radeon: disable CMASK on handle export if sharing doesn't allow it - Disabling CMASK and fast clear for shared resources. radeonsi: allocate DCC in the same backing buffer as the texture radeonsi: add DCC decompression (v2) radeonsi: disable DCC on handle export if expecting write access - DCC sharing or disabling it. radeonsi: accept pipe_resource in si_sampler_view_add_buffer radeonsi: remove resource field from si_sampler_view radeonsi: extract the buffer descriptor computation into its own function radeonsi: extract the texture descriptor computation into its own function - Nicolai's patches for GL_ARB_shader_image_load_store that I cherry-picked in order to get image descriptors without sampler views. The first 3 are dependencies of the 4th. radeonsi: set amdgpu metadata before exporting a texture - Finally writing image descriptors to metadata. winsys/amdgpu: get PCI info - Required by OpenCL for device identification.
