Update of /a/cvsroot/src/sys/arch/i386/i386
In directory netbsd1:/var/slash-tmp/cvs-serv15339
Modified Files:
genassym.c locore.s machdep.c pmap.c
Log Message:
Changes for NKPDE calculation from cgd.
- New variables: biosextmem, biosbasemem, nkpde
- Above can be set by using the options BIOSEXTMEM, BIOSBASEMEM,
and NKPDE respectively (EXTMEM_SIZE is now called BIOSEXTMEM).
When preset this way, they won't be filled in / calculated.
- Readable by sysctl using machdep.nkpde, machdep.biosbasemem
and machdep.biosextmem.
- nkpde is calculated as:
min(NKPDE_MAX, NKPDE_BASE + (biosextmem >> 10) * NKPDE_SCALE)
Where NKPDE_MAX is 31, NKPDE_BASE is 4, NKPDE_SCALE = 1.
