X68030 with 8MB or 12MB RAM (which is default for most X68030s) now gets "pmap_enter_ptpage: can't get KPT page" panic again with VM_KERNEL_PT_PAGES=2 while it works with >=14MB. 3 is enough to boot for now, but I also add a spare. I guess this is because the post netbsd-6 vmem(9) bootstrap changes require more kernel memory before MD pmap_init(). Note1: netbsd-6 (which also pulls physmem detection changes that affect nptpages) doesn't have this problem. Note2: other hp300 pmap based m68k ports might have the same issue, but at least 12MB luna68k works with VM_KERNEL_PT_PAGES=2 so I think it depends on kernel size and/or iomapsize. |
