2003-09-25 Yoshinori K. Okuji <okuji@enbug.org> I forgot to check in these changes for a long time. This adds incomplete support for VGA console, and this is still very buggy. Also, a lot of consideration is required for I18N, UNICODE, and VGA font issues. Therefore, assume that this is such that "better than nothing". * font/manager.c: New file. * include/pupa/font.h: Likewise. * include/pupa/i386/pc/vga.h: Likewise. * term/i386/pc/vga.c: Likewise. * util/unifont2pff.rb: Likewise. * conf/i386-pc.rmk (kernel_img_HEADERS): Added machine/vga.h. (pkgdata_MODULES): Added vga.mod and font.mod. (vga_mod_SOURCES): New variables. (vga_mod_CFLAGS): Likewise. (font_mod_SOURCES): Likewise. (font_mod_CFLAGS): Likewise. * include/pupa/err.h (PUPA_ERR_BAD_FONT): New constant. * include/pupa/term.h: Include pupa/err.h. (struct pupa_term): Added init and fini.
