29fea9cb91Slq * the like.
30aecfc01dSrui zang - Sun Microsystems - Beijing China *
31aecfc01dSrui zang - Sun Microsystems - Beijing China * How Virtual Terminal Emulator Works:
32aecfc01dSrui zang - Sun Microsystems - Beijing China *
33aecfc01dSrui zang - Sun Microsystems - Beijing China * Every virtual terminal is associated with a tem_vt_state structure
34aecfc01dSrui zang - Sun Microsystems - Beijing China * and maintains a virtual screen buffer in tvs_screen_buf, which contains
35aecfc01dSrui zang - Sun Microsystems - Beijing China * all the characters which should be shown on the physical screen when
36aecfc01dSrui zang - Sun Microsystems - Beijing China * the terminal is activated. There are also two other buffers, tvs_fg_buf
37aecfc01dSrui zang - Sun Microsystems - Beijing China * and tvs_bg_buf, which track the foreground and background colors of the
38aecfc01dSrui zang - Sun Microsystems - Beijing China * on screen characters
39aecfc01dSrui zang - Sun Microsystems - Beijing China *
40aecfc01dSrui zang - Sun Microsystems - Beijing China * Data written to a virtual terminal is composed of characters which
41aecfc01dSrui zang - Sun Microsystems - Beijing China * should be displayed on the screen when this virtual terminal is
42aecfc01dSrui zang - Sun Microsystems - Beijing China * activated, fg/bg colors of these characters, and other control
43aecfc01dSrui zang - Sun Microsystems - Beijing China * information (escape sequence, etc).
44aecfc01dSrui zang - Sun Microsystems - Beijing China *
45aecfc01dSrui zang - Sun Microsystems - Beijing China * When data is passed to a virtual terminal it first is parsed for
46aecfc01dSrui zang - Sun Microsystems - Beijing China * control information by tem_safe_parse(). Subsequently the character
47aecfc01dSrui zang - Sun Microsystems - Beijing China * and color data are written to tvs_screen_buf, tvs_fg_buf, and
48aecfc01dSrui zang - Sun Microsystems - Beijing China * tvs_bg_buf. They are saved in these buffers in order to refresh
49aecfc01dSrui zang - Sun Microsystems - Beijing China * the screen when this terminal is activated. If the terminal is
50aecfc01dSrui zang - Sun Microsystems - Beijing China * currently active, the data (characters and colors) are also written
51aecfc01dSrui zang - Sun Microsystems - Beijing China * to the physical screen by invoking a callback function,
52aecfc01dSrui zang - Sun Microsystems - Beijing China * tem_safe_text_callbacks() or tem_safe_pix_callbacks().
53aecfc01dSrui zang - Sun Microsystems - Beijing China *
54aecfc01dSrui zang - Sun Microsystems - Beijing China * When rendering data to the framebuffer, if the framebuffer is in
55aecfc01dSrui zang - Sun Microsystems - Beijing China * VIS_PIXEL mode, the character data will first be converted to pixel
56aecfc01dSrui zang - Sun Microsystems - Beijing China * data using tem_safe_pix_bit2pix(), and then the pixels get displayed
57aecfc01dSrui zang - Sun Microsystems - Beijing China * on the physical screen. We only store the character and color data in
58aecfc01dSrui zang - Sun Microsystems - Beijing China * tem_vt_state since the bit2pix conversion only happens when actually
59aecfc01dSrui zang - Sun Microsystems - Beijing China * rendering to the physical framebuffer.
