From 4bc9130fba2f815cb910536d3d3a253a8c3ed0b9 Mon Sep 17 00:00:00 2001 From: Edward O'Callaghan Date: Wed, 17 Feb 2016 20:59:52 +1100 Subject: gallium: Add PIPE_CAP_FRAMEBUFFER_NO_ATTACHMENT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add PIPE_CAP to determine if the GL extension 'GL_ARB_framebuffer_no_attachments' shall be supported. The driver is required to support 'PIPE_FORMAT_NONE' via its 'is_format_supported()' callback in order to determine the MSAA modes the hardware supports so that values requested from the application using 'GL_ARB_framebuffer_no_attachments' may be quantized to what the hardware expects. V.2: Fix doc for a more detailed description of the PIPE_CAP and the corresponding GL constant. V.3: Renamed and repurposed once again. V.4: Remove CAP from cap_mapping array.
