The main goals are:\n\n - Get rid of imalloc and use more common code where possible\n - Simplify the current mess so that PIO space is allocated and\n mapped in a single place for PCI bridges\n - Handle allocation constraints of PIO for all bridges including\n hot plugged ones within the 2GB space reserved for IO ports,\n so that devices on hotplugged busses will now work with drivers\n that assume IO ports fit in an int.\n - Cleanup and separate tracking of the ISA space in the reserved\n low 64K of IO space. No ISA -\u003e Nothing mapped there.\n\nI booted a cell blade with IDE on PIO and MMIO and a dual G5 so\nfar, that\u0027s it :-)\n\nWith this patch, all allocations are done using the code in\nmm/vmalloc.c, though we use the low level __get_vm_area with\nexplicit start/stop constraints in order to manage separate\nareas for vmalloc/vmap, ioremap, and PCI IOs.\n\nThis greatly simplifies a lot of things, as you can see in the\ndiffstat of that patch :-)\n\nA new pair of functions pcibios_map/unmap_io_space() now replace\nall of the previous code that used to manipulate PCI IOs space.\nThe allocation is done at mapping time, which is now called from\nscan_phb\u0027s, just before the devices are probed (instead of after,\nwhich is by itself a bug fix). The only other caller is the PCI\nhotplug code for hot adding PCI-PCI bridges (slots).\n\nimalloc is gone, as is the \"sub-allocation\" thing, but I do beleive\nthat hotplug should still work in the sense that the space allocation\nis always done by the PHB, but if you unmap a child bus of this PHB\n(which seems to be possible), then the code should properly tear\ndown all the HPTE mappings for that area of the PHB allocated IO space.\n\nI now always reserve the first 64K of IO space for the bridge with\nthe ISA bus on it. I have moved the code for tracking ISA in a separate\nfile which should also make it smarter if we ever are capable of\nhot unplugging or re-plugging an ISA bridge.\n\nThis should have a side effect on platforms like powermac where VGA IOs\nwill no longer work. This is done on purpose though as they would have\nworked semi-randomly before. The idea at this point is to isolate drivers\nthat might need to access those and fix them by providing a proper\nfunction to obtain an offset to the legacy IOs of a given bus.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "c19c03fc749147f565e807fa65f1729066800571", "tree": "d5ba2eb6d43b5001c93c42523fc5b2431ef61664", "parents": [ "3c8c90ab8810a8ebb38a5f1dde2595b750d5adff" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Mon Jun 04 15:15:35 2007 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Thu Jun 14 22:29:56 2007 +1000" }, "message": "[POWERPC] unmap_vm_area becomes unmap_kernel_range for the public\n\nThis makes unmap_vm_area static and a wrapper around a new\nexported unmap_kernel_range that takes an explicit range instead\nof a vm_area struct.\n\nThis makes it more versatile for code that wants to play with kernel\npage tables outside of the standard vmalloc area.\n\n(One example is some rework of the PowerPC PCI IO space mapping\ncode that depends on that patch and removes some code duplication\nand horrible abuse of forged struct vm_struct).\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "3f1df7a260aded4937e512872f3fbfdb9bc22c82", "tree": "84c14dc59169426f9389ecf09818c8d21f592bca", "parents": [ "31fe5bf66a09c36e95b4c04291249b251b52f2d4" ], "author": { "name": "Jon Tollefson", "email": "kniht@linux.vnet.ibm.com", "time": "Fri May 18 04:49:22 2007 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Thu Jun 14 22:29:55 2007 +1000" }, "message": "[POWERPC] Move common code out of if/else\n\nMove common code out of if/else.\n\nSigned-off-by: Jon Tollefson \u003ckniht@linux.vnet.ibm.com\u003e\n----\n\nhash_native_64.c | 3 +--\n 1 files changed, 1 insertion(+), 2 deletions(-)\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "f1aed92464def83fc3677cade823cad71cf5f0d4", "tree": "329d03317c6d65a4a610f04c84a968e5f0a67968", "parents": [ "405861a0429113f8e426092af09dd05ec6209410" ], "author": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Wed May 23 07:49:37 2007 -0500" }, "committer": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Wed May 23 07:49:37 2007 -0500" }, "message": "[POWERPC] Fix modpost warning\n\nMark pte_alloc_one_kernel as __init_refok to fix the following warning:\n\nWARNING: arch/powerpc/mm/built-in.o(.text+0x1068): Section mismatch: reference to .init.text:early_get_page (between \u0027pte_alloc_one_kernel\u0027 and \u0027steal_context\u0027)\n\nSigned-off-by: Kumar Gala \u003cgalak@kernel.crashing.org\u003e\n" }, { "commit": "5453e7723b95958f4591b2e0063573d8d53e7699", "tree": "3a12178ea3606270823b882d4f715dc33a9bea6b", "parents": [ "832a791c580a86cbeea5bb12a984d95b1f458539" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue May 22 16:25:51 2007 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Tue May 22 20:20:57 2007 +1000" }, "message": "[POWERPC] Fix warning in 32-bit builds with CONFIG_HIGHMEM\n\nSome missing fixup for the removal of 4 level fixup header.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "e8edc6e03a5c8562dc70a6d969f732bdb355a7e7", "tree": "fc86c863655128a7041dfe613d14393d761fa7b9", "parents": [ "ff1be9ad61e3e17ba83702d8ed0b534e5b8ee15c" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon May 21 01:22:52 2007 +0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon May 21 09:18:19 2007 -0700" }, "message": "Detach sched.h from mm.h\n\nFirst thing mm.h does is including sched.h solely for can_do_mlock() inline\nfunction which has \"current\" dereference inside.

Well, I re-used the mechanism used formerly by our\nhugetlbfs implementation which divides the address space in\n\"meta-segments\" which I called \"slices\". The division is done using\n256MB slices below 4G, and 1T slices above. Thus the address space is\ndivided currently into 16 \"low\" slices and 16 \"high\" slices. (Special\ncase: high slice 0 is the area between 4G and 1T).\n\nDoing so simplifies significantly the tracking of segments and avoids\nhaving to keep track of all the 256MB segments in the address space.\n\nWhile I used the \"concepts\" of hugetlbfs, I mostly re-implemented\neverything in a more generic way and \"ported\" hugetlbfs to it.\n\nSlices can have an associated page size, which is encoded in the mmu\ncontext and used by the SLB miss handler to set the segment sizes. The\nhash code currently doesn\u0027t care, it has a specific check for hugepages,\nthough I might add a mechanism to provide per-slice hash mapping\nfunctions in the future.\n\nThe slice code provide a pair of \"generic\" get_unmapped_area() (bottomup\nand topdown) functions that should work with any slice size. There is\nsome trickiness here so I would appreciate people to have a look at the\nimplementation of these and let me know if I got something wrong.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "16f1c746755836aa823658000493cdab8ce7b098", "tree": "32f534c771b69400839f5795f979c47eac51f923", "parents": [ "b15f792fafb7e0524907ddd9e035d73dddeed89c" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue May 08 16:27:27 2007 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Wed May 09 16:35:00 2007 +1000" }, "message": "[POWERPC] Small fixes \u0026 cleanups in segment page size demotion\n\nThe code for demoting segments to 4K had some issues, like for example,\nwhen using _PAGE_4K_PFN flag, the first CPU to hit it would do the\ndemotion, but other CPUs hitting the same page wouldn\u0027t properly flush\ntheir SLBs if mmu_ci_restriction isn\u0027t set.

I\u0027ll try to address that separately, I\u0027m not 100% certain yet how,\npossibly by making it not work when the vma has a file whose f_ops has a\nget_unmapped_area callback, and by making it use is_hugepage_only_range()\nbefore expanding into a new area.\n\nAlso, I want to turn is_hugepage_only_range() into a more generic\nis_normal_page_range() as that\u0027s really what it will end up meaning when used\nin stack grow, brk grow and mremap.\n\nNone of the above \"issues\" however are introduced by this patch, they are\nalready there, so I think the patch can go ini for 2.6.22.\n\nThis patch:\n\nHandle MAP_FIXED in powerpc\u0027s arch_get_unmapped_area() in all 3\nimplementations of it.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nAcked-by: William Irwin \u003cbill.irwin@oracle.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Richard Henderson \u003crth@twiddle.net\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: Matthew Wilcox \u003cwilly@debian.org\u003e\nCc: \"David S.

On a kernel configured with 64k pages\nwe currently end up mapping the 4k we want plus another 60k of\nphysical address space, which could contain anything. This can\nintroduce security problems, for example in the case of an infiniband\nadaptor where the other 60k could contain registers that some other\nprogram is using for its communications.\n\nThis patch adds a new function, remap_4k_pfn, which drivers can use to\nmap a single 4k page to userspace regardless of whether the kernel is\nusing a 4k or a 64k page size. Like remap_pfn_range, it would\ntypically be called in a driver\u0027s mmap function. It only maps a\nsingle 4k page, which on a 64k page kernel appears replicated 16 times\nthroughout a 64k page. On a 4k page kernel it reduces to a call to\nremap_pfn_range.\n\nThe way this works on a 64k kernel is that a new bit, _PAGE_4K_PFN,\ngets set on the linux PTE. This alters the way that __hash_page_4K\ncomputes the real address to put in the HPTE. The RPN field of the\nlinux PTE becomes the 4k RPN directly rather than being interpreted as\na 64k RPN. Since the RPN field is 32 bits, this means that physical\naddresses being mapped with remap_4k_pfn have to be below 2^44,\ni.e. 0x100000000000.\n\nThe patch also factors out the code in arch/powerpc/mm/hash_utils_64.c\nthat deals with demoting a process to use 4k pages into one function\nthat gets called in the various different places where we need to do\nthat. There were some discrepancies between exactly what was done in\nthe various places, such as a call to spu_flush_all_slbs in one case\nbut not in others.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "9213feea6e197f8507ec855337798cc3388f5570", "tree": "da8015e33f1a242a050ef62603bdc53a7982441c", "parents": [ "a8bda5dd4f99d6469f3c0dc362db3cce8a4d6416" ], "author": { "name": "Stephen Rothwell", "email": "sfr@canb.auug.org.au", "time": "Tue Apr 03 10:57:48 2007 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Fri Apr 13 03:55:18 2007 +1000" }, "message": "[POWERPC] Rename prom_n_size_cells to of_n_size_cells\n\nThis is more consistent and gets us closer to the Sparc code.\n\nSigned-off-by: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "a8bda5dd4f99d6469f3c0dc362db3cce8a4d6416", "tree": "513cb0896e142b5eca6fd445cde11b651f408824", "parents": [ "7a92f74f98bde8498c98aad6cac5da5a87dd0bf4" ], "author": { "name": "Stephen Rothwell", "email": "sfr@canb.auug.org.au", "time": "Tue Apr 03 10:56:50 2007 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Fri Apr 13 03:55:18 2007 +1000" }, "message": "[POWERPC] Rename prom_n_addr_cells to of_n_addr_cells\n\nThis is more consistent and gets us closer to the Sparc code.\n\nSigned-off-by: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "e049d1ca3094f3d1d94617f456a9961202f96e3a", "tree": "a30397ad22f2fbea268bd28fa69c60aad9dfa62a", "parents": [ "edfac96a92b88d3b0b53e3f8231b74beee9ecd1d", "80584ff3b99c36ead7e130e453b3a48b18072d18" ], "author": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Fri Apr 13 03:50:03 2007 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Fri Apr 13 03:50:03 2007 +1000" }, "message": "Merge branch \u0027linux-2.6\u0027 into for-2.6.22\n" }, { "commit": "94b2a4393c500a620de90c3266d595926302e26b", "tree": "cde58177f430751b67a7aa47f3f89042e91357bf", "parents": [ "50b520d4efbce45281f58112789470ec7965fd33" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Sat Mar 10 00:05:37 2007 +0100" }, "committer": { "name": "Arnd Bergmann", "email": "arnd@klappe.arndb.de", "time": "Sat Mar 10 00:07:50 2007 +0100" }, "message": "[POWERPC] Fix spu SLB invalidations\n\nThe SPU code doesn\u0027t properly invalidate SPUs SLBs when necessary,\nfor example when changing a segment size from the hugetlbfs code.

This\nset of patch target shared page table for hugetlb memory only.\n\nThe shared page table is particular useful in the situation of large number of\nindependent processes sharing large shared memory segments. In the normal\npage case, the amount of memory saved from process\u0027 page table is quite\nsignificant. For hugetlb, the saving on page table memory is not the primary\nobjective (as hugetlb itself already cuts down page table overhead\nsignificantly), instead, the purpose of using shared page table on hugetlb is\nto allow faster TLB refill and smaller cache pollution upon TLB miss.\n\nWith PT sharing, pte entries are shared among hundreds of processes, the cache\nconsumption used by all the page table is smaller and in return, application\ngets much higher cache hit ratio. One other effect is that cache hit ratio\nwith hardware page walker hitting on pte in cache will be higher and this\nhelps to reduce tlb miss latency. These two effects contribute to higher\napplication performance.\n\nSigned-off-by: Ken Chen \u003ckenneth.w.chen@intel.com\u003e\nAcked-by: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Dave McCracken \u003cdmccr@us.ibm.com\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: \"David S.
