Rodney W. Grimes c77ba36045 Fix definitions to be in terms of a minimum number of constants by ... using the SHIFT value as the basis for the other values, for example instead of: #define NBPG 4096 #define PGSHIFT 12 use: #define PGSHIFT 12 #define NBPG (1 << PGSHIFT) =================================================================== RCS file: /a/cvs/386BSD/src/sys/i386/include/param.h,v retrieving revision 1.3 diff -c -r1.3 param.h *** 1.3 1993/10/08 12:49:55 --- param.h 1993/10/08 12:53:19 *************** *** 52,76 **** #define ALIGNBYTES (sizeof(int) - 1) #define ALIGN(p) (((u_int)(p) + ALIGNBYTES) &~ ALIGNBYTES) - #define NBPG 4096 /* bytes/page */ - #define PGOFSET (NBPG-1) /* byte offset into page */ #define PGSHIFT 12 /* LOG2(NBPG) */ #define NPTEPG (NBPG/(sizeof (struct pte))) - #define NBPDR (1024*NBPG) /* bytes/page dir */ - #define PDROFSET (NBPDR-1) /* byte offset into page dir */ #define PDRSHIFT 22 /* LOG2(NBPDR) */ #define KERNBASE 0xFE000000 /* start of kernel virtual */ #define BTOPKERNBASE ((u_long)KERNBASE >> PGSHIFT) ! #define DEV_BSIZE 512 #define DEV_BSHIFT 9 /* log2(DEV_BSIZE) */ #define BLKDEV_IOSIZE 2048 #define MAXPHYS (64 * 1024) /* max raw I/O transfer size */ - #define CLSIZE 1 #define CLSIZELOG2 0 /* NOTE: SSIZE, SINCR and UPAGES must be multiples of CLSIZE */ #define SSIZE 1 /* initial stack size/NBPG */ --- 52,79 ---- #define ALIGNBYTES (sizeof(int) - 1) #define ALIGN(p) (((u_int)(p) + ALIGNBYTES) &~ ALIGNBYTES) #define PGSHIFT 12 /* LOG2(NBPG) */ + #define NBPG (1 << PGSHIFT) /* bytes/page */ + #define PGOFSET (NBPG-1) /* byte offset into page */ #define NPTEPG (NBPG/(sizeof (struct pte))) #define PDRSHIFT 22 /* LOG2(NBPDR) */ + #define NBPDR (1 << PDRSHIFT) /* bytes/page dir */ + #define PDROFSET (NBPDR-1) /* byte offset into page dir */ #define KERNBASE 0xFE000000 /* start of kernel virtual */ #define BTOPKERNBASE ((u_long)KERNBASE >> PGSHIFT) ! #define KERNSIZE 0x00C00000 /* size of kernel virtual */ ! #define DEV_BSHIFT 9 /* log2(DEV_BSIZE) */ + #define DEV_BSIZE (1 << DEV_BSHIFT) + #define BLKDEV_IOSIZE 2048 #define MAXPHYS (64 * 1024) /* max raw I/O transfer size */ #define CLSIZELOG2 0 + #define CLSIZE (1 << CLSIZELOG2) /* NOTE: SSIZE, SINCR and UPAGES must be multiples of CLSIZE */ #define SSIZE 1 /* initial stack size/NBPG */ *************** *** 92,99 **** #ifndef MCLSHIFT #define MCLSHIFT 11 /* convert bytes to m_buf clusters */ #endif /* MCLSHIFT */ ! #define MCLBYTES (1 << MCLSHIFT) /* size of a m_buf cluster */ ! #define MCLOFSET (MCLBYTES - 1) /* offset within a m_buf cluster */ #ifndef NMBCLUSTERS #ifdef GATEWAY --- 95,102 ---- #ifndef MCLSHIFT #define MCLSHIFT 11 /* convert bytes to m_buf clusters */ #endif /* MCLSHIFT */ ! #define MCLBYTES (1 << MCLSHIFT) /* size of an m_buf cluster */ ! #define MCLOFSET (MCLBYTES - 1) /* offset within an m_buf cluster */ #ifndef NMBCLUSTERS #ifdef GATEWAY		1993-10-08 13:01:34 +00:00
