With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant.

simplification of implementation with 256KB pages we still assume\n2-level paging. As a side effect this leads to wasting extra memory space\nreserved for PTE tables: only 1/4 of pages allocated for PTEs are\nactually used. But this may be an acceptable trade-off to achieve the\nhigh performance we have with big PAGE_SIZEs in some applications (e.g.\nRAID).\n\nAlso with 256KB PAGE_SIZE we increase THREAD_SIZE up to 32KB to minimize\nthe risk of stack overflows in the cases of on-stack arrays, which size\ndepends on the page size (e.g. multipage BIOs, NTFS, etc.).\n\nWith 256KB PAGE_SIZE we need to decrease the PKMAP_ORDER at least down\nto 9, otherwise all high memory (2 ^ 10 * PAGE_SIZE \u003d\u003d 256MB) we\u0027ll be\noccupied by PKMAP addresses leaving no place for vmalloc. We do not\nseparate PKMAP_ORDER for 256K from 16K/64K PAGE_SIZE here; actually that\nvalue of 10 in support for 16K/64K had been selected rather intuitively.\nThus now for all cases of PAGE_SIZE on ppc44x (including the default, 4KB,\none) we have 512 pages for PKMAP.\n\nBecause ELF standard supports only page sizes up to 64K, then you should\nuse binutils later than 2.17.50.0.3 with \u0027-zmax-page-size\u0027 set to 256K\nfor building applications, which are to be run with the 256KB-page sized\nkernel. If using the older binutils, then you should patch them like follows:\n\n\t--- binutils/bfd/elf32-ppc.c.orig\n\t+++ binutils/bfd/elf32-ppc.c\n\n\t-#define ELF_MAXPAGESIZE 0x10000\n\t+#define ELF_MAXPAGESIZE 0x40000\n\nOne more restriction we currently have with 256KB page sizes is inability\nto use shmem safely, so, for now, the 256KB is available only if you turn\nthe CONFIG_SHMEM option off (another variant is to use BROKEN).\nThough, if you need shmem with 256KB pages, you can always remove the !SHMEM\ndependency in \u0027config PPC_256K_PAGES\u0027, and use the workaround available here:\n http://lkml.org/lkml/2008/12/19/20\n\nSigned-off-by: Yuri Tikhonov \u003cyur@emcraft.com\u003e\nSigned-off-by: Ilya Yanok \u003cyanok@emcraft.com\u003e\nSigned-off-by: Josh Boyer \u003cjwboyer@linux.vnet.ibm.com\u003e\n" }, { "commit": "d0839118f396f6d7af553e99ad204aa2b3209cde", "tree": "30435e0748176ac46344a6c0d97fb3dd7108b492", "parents": [ "f7a0be456f1bdcb6dec81c1e4e47e2b7205eba95" ], "author": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Wed Jan 28 13:25:29 2009 -0600" }, "committer": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Wed Jan 28 18:17:02 2009 -0600" }, "message": "powerpc/fsl: Ensure PCI_QUIRKS are enabled for FSL_PCI\n\nThe FSL PCI code depends on PCI quirks being enabled to function\nproperly.

On E500v2 pages up to 4 GB are supported.\n\nHowever, a page must be aligned to a multiple of the page\u0027s size. I.e.\n256 MB pages must aligned to a 256 MB boundary. This was enforced by a\nrequirement that the physical and virtual addresses of the start of lowmem\nbe aligned to 256 MB. Clearly requiring 1GB or 4GB alignment to allow\npages of that size isn\u0027t acceptable.\n\nTo solve this, I simply have adjust_total_lowmem() take alignment into\naccount when it decides what size pages to use. Give it PAGE_OFFSET \u003d\n0x7000_0000, PHYSICAL_START \u003d 0x3000_0000, and 2GB of RAM, and it will map\npages like this:\nPA 0x3000_0000 VA 0x7000_0000 Size 256 MB\nPA 0x4000_0000 VA 0x8000_0000 Size 1 GB\nPA 0x8000_0000 VA 0xC000_0000 Size 256 MB\nPA 0x9000_0000 VA 0xD000_0000 Size 256 MB\nPA 0xA000_0000 VA 0xE000_0000 Size 256 MB\n\nBecause the lowmem mapping code now takes alignment into account,\nPHYSICAL_ALIGN can be lowered from 256 MB to 64 MB. Even lower might be\npossible. The lowmem code will work down to 4 kB but it\u0027s possible some of\nthe boot code will fail before then. Poor alignment will force small pages\nto be used, which combined with the limited number of TLB1 pages available,\nwill result in very little memory getting mapped. So alignments less than\n64 MB probably aren\u0027t very useful anyway.\n\nSigned-off-by: Trent Piepho \u003ctpiepho@freescale.com\u003e\nSigned-off-by: Kumar Gala \u003cgalak@kernel.crashing.org\u003e\n" }, { "commit": "52c275fe70df8619e9430d01917d2e72e9011aec", "tree": "693d6df30577a9d02f84f3df9527652eaa6d1a41", "parents": [ "802bdea875ed8c682bb30f71d762ce727ab8bb87" ], "author": { "name": "Josh Boyer", "email": "jwboyer@linux.vnet.ibm.com", "time": "Tue Jan 20 05:16:36 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Jan 28 17:15:51 2009 +1100" }, "message": "powerpc: Remove arch/ppc cruft from Kconfig\n\nRemove some leftover cruft from the arch/ppc days\n\nSigned-off-by: Josh Boyer \u003cjwboyer@linux.vnet.ibm.com\u003e\nAcked-by: Kumar Gala \u003cgalak@kernel.crashing.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "ee6a093222549ac0c72cfd296c69fa5e7d6daa34", "tree": "8f1788edc08009b80ee299b843cdc7bf3ac4bcdc", "parents": [ "1a94bc34768e463a93cb3751819709ab0ea80a01" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Jan 14 14:14:00 2009 +0100" }, "committer": { "name": "Heiko Carstens", "email": "heiko.carstens@de.ibm.com", "time": "Wed Jan 14 14:15:17 2009 +0100" }, "message": "[CVE-2009-0029] powerpc: Enable syscall wrappers for 64-bit\n\nThis enables the use of syscall wrappers to do proper sign extension\nfor 64-bit programs.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\n" }, { "commit": "2b79d6962322facfd377a402730e4b381af95a40", "tree": "cc0ea598b663ead982b14b706b9f24d96493130a", "parents": [ "9b635642bce0500bdc7331ce8eeca97907b77117" ], "author": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Tue Jan 06 18:49:17 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Jan 08 16:25:18 2009 +1100" }, "message": "powerpc: enable dynamic ftrace\n\nThis patch enables dynamic ftrace.
