Hi lists, Before asking for review of the patch regarding PAE support inside native i386 kernel (inspired from jmorse@ work from a few weeks ago), I would like to commit these beforehand ([1] & [2]). I made them separate because they are not for PAE support "per-see."
They are mostly types + cosmetic fixes. As some of you may now, introducing PAE affects the x86 paradigm inside NetBSD a bit: - sizeof paddr_t != sizeof vaddr_t (64 bits for paddr_t, 32 bits for vaddr_t) - "unsigned long" cannot be considered as a physical address anymore This affect a couple of printfs(), printk() and debugging messages, as well as some variables types used inside x86 pmap [1]. Second small patch [2] contains fixes regarding UVM: - RLIMIT_RSS which is now set to VM_MAXUSER_ADDRESS (shouldn't it be set to MIN(VM_MAXUSER_ADDRESS, ptoa(uvmexp.free) instead?), - ptoa => ctob use (to avoid vaddr_t casts, which might be bad for systems with total RAM > 4GB) - a small fix inside AGP heuristics to avoid masking high order bits Compile tested for ALL, GENERIC, XEN3 kernels for i386, and GENERIC, XEN3* for amd64. In case someone wonders, if PAE is added as default option for ALL, more fixes will be needed in some drivers under sys/dev/ (paddr_t vs unsigned long issues). Question is: should it be added to ALL for additional checks? Opinions welcomed.
