Unfortunately, no similar 40 * workaround exists for lint's pass2, which requires definitions for all 41 * symbols in order to properly perform cross-checks. 42 * 43 * Thus, this header file was created to address two problems: 44 * 45 * 1. The "extern" problem. All files beneath stand/lib should #include 46 * this file rather than "extern" the symbol. Additionally, existing 47 * externs should be removed as convenient. 48 * 49 * Of course, eventually some brave soul needs to venture over to the 50 * slums of psm/stand and add all the proper header files, at which 51 * point this file can be disposed of. 52 * 53 * 2. The lint pass2 problem. Specifically, this file is used to build 54 * llib-lfakeboot.ln, which is then used to properly lint the 55 * binaries under stand/lib. See stand/lib/llib-lfakeboot for more 56 * details. 57 * 58 * Note that the set of symbols shared between stand/lib and psm/stand is 59 * itself a moving target. As such, this file should be updated as needed 60 * so that it always contains the *minimum* set of shared symbols needed to 61 * avoid externs and placate lint. 62 */ 63 64 #include <sys/saio.h> 65 66 #ifdef __cplusplus 67 extern "C" { 68 #endif 69 70 /* 71 * From psm/stand/boot/$(MACH)/common/fsconf.c: 72 */ 73 extern int nfs_readsize; 74 extern int boot_nfsw; 75 extern struct boot_fs_ops *boot_fsw[]; 76 extern struct boot_fs_ops *extendfs_ops; 77 extern struct boot_fs_ops *origfs_ops; 78 79 /* 80 * From psm/stand/boot/common/boot.c: 81 */ 82 extern int boothowto; 83 extern int verbosemode; 84 extern char *systype; 85 extern struct memlist *pfreelistp; 86 extern struct memlist *vfreelistp; 87 extern void set_default_filename(char *); 88 89 /* 90 * From psm/stand/boot/common/heap_kmem.c: 91 */ 92 extern void *bkmem_alloc(size_t); 93 extern void *bkmem_zalloc(size_t); 94 extern void bkmem_free(void *, size_t); 95 96 /* 97 * From psm/stand/boot/$(MACH)/common/$(MACH)_standalloc.c: 98 */ 99 extern caddr_t resalloc(enum RESOURCES, size_t, caddr_t, int); 100 extern void resfree(enum RESOURCES, caddr_t, size_t); 101 extern void reset_alloc(void); 102 103 /* 104 * From psm/stand/lib/names/$(MACH)/common/mfgname.c: (libnames) 105 */ 106 extern char *get_mfg_name(void); 107 108 /* 109 * From psm/stand/boot/i386/common/boot_plat.c or 110 * psm/stand/boot/sparcv9/sun4u/machdep.c: 111 */ 112 extern int pagesize; 113 extern int global_pages; 114 115 #ifdef __sparc 116 /* 117 * From psm/stand/boot/sparc/common/fsconf.c: 118 */ 119 extern char *bootp_response; 120 121 /* 122 * From psm/stand/boot/sparc/common/wanboot.c: 123 */ 124 extern char *bootcfg; 125 #endif /* __sparc */ 126 127 #ifdef __cplusplus 128 } 129 #endif 130 131 #endif /* _SYS_BOOTSYMS_H */ 132
