/** * r600_cs_common_vline_parse() - common vline parser * @parser: parser structure holding parsing context. * @vline_start_end: table of vline_start_end registers * @vline_status: table of vline_status registers * * Userspace sends a special sequence for VLINE waits. * PACKET0 - VLINE_START_END + value * PACKET3 - WAIT_REG_MEM poll vline status reg * RELOC (P3) - crtc_id in reloc. * * This function parses this and relocates the VLINE START END * and WAIT_REG_MEM packets to the correct crtc. * It also detects a switched off crtc and nulls out the * wait in that case. This function is common for all ASICs that * are R600 and newer. The parsing algorithm is the same, and only * differs in which registers are used. * * Caller is the ASIC-specific function which passes the parser * context and ASIC-specific register table */
