From e28f7faf05159f1cfd564596f5e6178edba6bd49 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Fri, 5 Aug 2005 19:39:06 +1000 Subject: [PATCH] Four level pagetables for ppc64 Implement 4-level pagetables for ppc64 This patch implements full four-level page tables for ppc64, thereby extending the usable user address range to 44 bits (16T). The patch uses a full page for the tables at the bottom and top level, and a quarter page for the intermediate levels. It uses full 64-bit pointers at every level, thus also increasing the addressable range of physical memory. This patch also tweaks the VSID allocation to allow matching range for user addresses (this halves the number of available contexts) and adds some #if and BUILD_BUG sanity checks.

The only tool which appears to access the naca is addRamDisk, but both the in-kernel version and the version used in RHEL and SuSE in fact locate the NACA the same way as the hypervisor does, by following the pointer in the hvReleaseData structure. Since the requirement for a fixed address seems to be obsolete, this patch removes the naca from head.S and replaces it with a normal C initializer. For good measure, it removes an old version of addRamDisk.c which was sitting, unused, in the ppc32 tree.

The following is for my benefit as much as everyone else. With CONFIG_MSCHUNKS enabled, the lmb code is changed such that it keeps a physbase variable for each lmb region. This is used to take the possibly discontiguous lmb regions and present them as a contiguous address space beginning from zero. In this context each lmb region's base address is its "absolute" base address, and its physbase is it's "physical" address (from Linux's point of view). The abs_to_phys() macro does the mapping from "absolute" to "physical". Note: This is not related to the iSeries mapping of physical to absolute (ie. Hypervisor) addresses which is maintained with the msChunks structure. And the msChunks structure is not controlled via CONFIG_MSCHUNKS. Once upon a time you could compile for non-iSeries with CONFIG_MSCHUNKS enabled. But these days CONFIG_MSCHUNKS depends on CONFIG_PPC_ISERIES, so for non-iSeries code abs_to_phys() is a no-op. On iSeries we always have one lmb region which spans from 0 to systemcfg->physicalMemorySize (arch/ppc64/kernel/iSeries_setup.c line 383). This region has a base (ie. absolute) address of 0, and a physbase address of 0 (as calculated in lmb_analyze() (arch/ppc64/kernel/lmb.c line 144)). On iSeries, abs_to_phys(aa) is defined as lmb_abs_to_phys(aa), which finds the lmb region containing aa (and there's only one, ie. 0), and then does: return lmb.memory.region[0].physbase + (aa - lmb.memory.region[0].base) physbase == base == 0, so you're left with "return aa". So remove abs_to_phys(), and lmb_abs_to_phys() which is the implementation of abs_to_phys() for iSeries.

Relax address restrictions for hugepages on ppc64 Presently, 64-bit applications on ppc64 may only use hugepages in the address region from 1-1.5T. Furthermore, if hugepages are enabled in the kernel config, they may only use hugepages and never normal pages in this area. This patch relaxes this restriction, allowing any address to be used with hugepages, but with a 1TB granularity. That is if you map a hugepage anywhere in the region 1TB-2TB, that entire area will be reserved exclusively for hugepages for the remainder of the process's lifetime. This works analagously to hugepages in 32-bit applications, where hugepages can be mapped anywhere, but with 256MB (mmu segment) granularity. This patch applies on top of the four level pagetable patch (http://patchwork.ozlabs.org/linuxppc64/patch?id=1936).
