gallium: split transfer_inline_write into buffer and texture callbacks
to reduce the call indirections with u_resource_vtbl. The worst call tree you could get was: - u_transfer_inline_write_vtbl - u_default_transfer_inline_write - u_transfer_map_vtbl - driver_transfer_map - u_transfer_unmap_vtbl - driver_transfer_unmap That's 6 indirect calls. Some drivers only had 5. The goal is to have 1 indirect call for drivers that care. The resource type can be determined statically at most call sites. The new interface is: pipe_context::buffer_subdata(ctx, resource, usage, offset, size, data) pipe_context::texture_subdata(ctx, resource, level, usage, box, data, stride, layer_stride) v2: fix whitespace, correct ilo's behavior Reviewed-by: Nicolai Hähnle <[email protected]> Acked-by: Roland Scheidegger <[email protected]>
