I\u0027m not entirely certain of why, I susepct they often contained\ngarbage on x86 but it\u0027s hard to tell. This causes the current generic\ncode to always call pci_assign_resource() when trying to access the said\nROM from sysfs, which will try to re-assign some new address regardless\nof what the ROM BAR was already set to at boot time. This can be a\nproblem on hypervisor platforms like pSeries where we aren\u0027t supposed\nto move PCI devices around (and in fact probably can\u0027t).\n\nSecond, our code that generates the PCI tree from the OF device-tree\n(instead of doing config space probing) which we mostly use on pseries\nat the moment, didn\u0027t set the (new) flag IORESOURCE_SIZEALIGN on any\nresource. That means that any attempt at re-assigning such a resource\nwith pci_assign_resource() would fail due to resource_alignment()\nreturning 0.\n\nThis fixes this by doing these two things:\n\n - The code that calculates resource flags based on the OF device-node\nis improved to set IORESOURCE_SIZEALIGN on any valid BAR, and while at\nit also set IORESOURCE_READONLY for ROMs since we were lacking that too\n\n - We now allocate ROM resources as part of the resource tree. However\nto limit the chances of nasty conflicts due to busted firmwares, we\nonly do it on the second pass of our two-passes allocation scheme,\nso that all valid and enabled BARs get precedence.\n\nThis brings pSeries back the ability to access PCI ROMs via sysfs (and\nthus initialize various video cards from X etc...).\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "b173f03d7c48d3346541f26e0b29690dbadca279", "tree": "9eec335a778a6bb715feb4fd0b000fa091d02b0f", "parents": [ "951c4df5b7703137bf4eee002d98d083fbc890cc" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu May 14 18:34:06 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri May 15 16:43:42 2009 +1000" }, "message": "powerpc/pseries: Really fix the oprofile CPU type on pseries\n\nMy previous pach for fixing the oprofile CPU type got somewhat mismerged\n(by my fault) when it collided with another related patch.

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": "8f8573ae9f5deefada6f5d64d0a52c9b39c730c7", "tree": "444d55bfb8a048ad3b13051cd55a64b688915a58", "parents": [ "37bed90094fdb1eea6e4afec6a200d4e60143e55", "0e43785c57fee50fbc00ea0378e941efb61fa0c2", "005bf0e6fa0e9543933fe2e36322af649df7cacb", "548c8933801c9ee347b6f1bad2491e4286a4f3a2" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 13 11:57:18 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 13 11:57:18 2009 +0100" }, "message": "Merge branches \u0027irq/genirq\u0027, \u0027irq/sparseirq\u0027 and \u0027irq/urgent\u0027 into irq/core\n" }, { "commit": "f8a6b2b9cee298a9663cbe38ce1eb5240987cb62", "tree": "b356490269c9e77d164dcc1477792b882fbb8bdb", "parents": [ "ba1511bf7fbda452138e4096bf10d5a382710f4f", "071a0bc2ceace31266836801510879407a3701fa" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 13 09:44:22 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 13 09:44:22 2009 +0100" }, "message": "Merge branch \u0027linus\u0027 into x86/apic\n\nConflicts:\n\tarch/x86/kernel/acpi/boot.c\n\tarch/x86/mm/fault.c\n" }, { "commit": "26456dcfb8d8e43b1b64b2a14710694cf7a72f05", "tree": "2a655c7515a5c27ea20a51a206e4d3b8df0edcba", "parents": [ "0047656e2a97d4452dd7df9e52591a7afe21a263" ], "author": { "name": "Michael Neuling", "email": "mikey@neuling.org", "time": "Thu Feb 12 19:08:58 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Feb 13 16:37:45 2009 +1100" }, "message": "powerpc/vsx: Fix VSX alignment handler for regs 32-63\n\nFix the VSX alignment handler for VSX registers \u003e 32. 32-63 are stored\nin the VMX part of the thread_struct not the FPR part.\n\nSigned-off-by: Michael Neuling \u003cmikey@neuling.org\u003e\nCC: stable@kernel.org (2.6.27 \u0026 .28 please)\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "70fe3af8403f85196bb74f22ce4813db7dfedc1a", "tree": "e82d3e5ee4b93b0a336df183d6dff5fe04cccab6", "parents": [ "d66c82ea456853a71d88359b0c19a92ac1d393ff" ], "author": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Thu Feb 12 16:12:40 2009 -0600" }, "committer": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Thu Feb 12 16:51:33 2009 -0600" }, "message": "powerpc/book-3e: Introduce concept of Book-3e MMU\n\nThe Power ISA 2.06 spec introduces a standard MMU programming model that\nis based on the Freescale Book-E MMU programing model.
