It implements the\nfollowing features:\n\n- Backup/restore memory used by the original kernel before/after\n kexec.\n\n- Save/restore CPU state before/after kexec.\n\nThe features of this patch can be used as a general method to call program in\nphysical mode (paging turning off). This can be used to call BIOS code under\nLinux.\n\nkexec-tools needs to be patched to support kexec jump. The patches and\nthe precompiled kexec can be download from the following URL:\n\n source: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-src_git_kh10.tar.bz2\n patches: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-patches_git_kh10.tar.bz2\n binary: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec_git_kh10\n\nUsage example of calling some physical mode code and return:\n\n1. Compile and install patched kernel with following options selected:\n\nCONFIG_X86_32\u003dy\nCONFIG_KEXEC\u003dy\nCONFIG_PM\u003dy\nCONFIG_KEXEC_JUMP\u003dy\n\n2. Build patched kexec-tool or download the pre-built one.\n\n3. Build some physical mode executable named such as \"phy_mode\"\n\n4. Boot kernel compiled in step 1.\n\n5. Load physical mode executable with /sbin/kexec. The shell command\n line can be as follow:\n\n /sbin/kexec --load-preserve-context --args-none phy_mode\n\n6. Call physical mode executable with following shell command line:\n\n /sbin/kexec -e\n\nImplementation point:\n\nTo support jumping without reserving memory. One shadow backup page (source\npage) is allocated for each page used by kexeced code image (destination\npage). When do kexec_load, the image of kexeced code is loaded into source\npages, and before executing, the destination pages and the source pages are\nswapped, so the contents of destination pages are backupped. Before jumping\nto the kexeced code image and after jumping back to the original kernel, the\ndestination pages and the source pages are swapped too.\n\nC ABI (calling convention) is used as communication protocol between\nkernel and called code.\n\nA flag named KEXEC_PRESERVE_CONTEXT for sys_kexec_load is added to\nindicate that the loaded kernel image is used for jumping back.\n\nNow, only the i386 architecture is supported.\n\nSigned-off-by: Huang Ying \u003cying.huang@intel.com\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nCc: \"Eric W.

For\nnon-pSeries platforms the code is ifdef\u0027ed out and for non-CMO enabled\npSeries systems this does not affect the normal code path. Devices that\ndo not perform DMA operations do not need modification with this patch.\nThe function get_desired_dma was renamed from get_io_entitlement for\nclarity.\n\nOverview\n\nCooperative Memory Overcommitment (CMO) allows for a set of OS partitions\nto be run with less RAM than the aggregate needs of the group of\npartitions. The firmware will balance memory between the partitions\nand page in/out memory as needed. Based on the number and type of IO\nadpaters preset each partition is allocated an amount of memory for\nDMA operations and this allocation will be guaranteed to the partition;\nthis is referred to as the partition\u0027s \u0027entitlement\u0027.\n\nPartitions running in a CMO environment can only have virtual IO devices\npresent. The VIO bus layer will manage the IO entitlement for the system.\nAccounting, at a system and per-device level, is tracked in the VIO bus\ncode and exposed via sysfs. A set of dma_ops functions are added to\nthe bus to allow for this accounting.\n\nBus initialization\n\nAt initialization, the bus will calculate the minimum needs of the system\nbased on providing each device present with a standard minimum entitlement\nalong with a spare allocation for the bus to handle hotplug events.\nIf the minimum needs can not be met the system boot will be halted.\n\nDevice changes\n\nThe significant changes for devices while running under CMO are that the\ndevices must specify how much dedicated IO entitlement they desire and\nmust also handle DMA mapping errors that can occur due to constrained\nIO memory. The virtual IO drivers are modified to silence errors when\nDMA mappings fail for CMO and handle these failures gracefully.\n\nEach devices will be guaranteed a minimum entitlement that can always\nbe mapped. Devices will specify how much entitlement they desire and\nthe VIO bus will attempt to provide for this. Devices can change their\ndesired entitlement level at any point in time to address particular needs\n(via vio_cmo_set_dev_desired()), not just at device probe time.\n\nVIO bus changes\n\nThe system will have a particular entitlement level available from which\nit can provide memory to the devices. The bus defines two pools of memory\nwithin this entitlement, the reserved and excess pools. Each device is\nprovided with it\u0027s own entitlement no less than a system defined minimum\nentitlement and no greater than what the device has specified as it\u0027s\ndesired entitlement. The entitlement provided to devices comes from the\nreserve pool. The reserve pool can also contain a spare allocation as\nlarge as the system defined minimum entitlement which is used for device\nhotplug events. Any entitlement not needed to fulfill the needs of a\nreserve pool is placed in the excess pool. Each device is guaranteed\nthat it can map up to it\u0027s entitled level; additional mapping are possible\nas long as there is unmapped memory in the excess pool.\n\nBus probe\n\nAs the system starts, each device is given an entitlement equal only\nto the system defined minimum entitlement. The reserve pool is equal\nto the sum of these entitlements, plus a spare allocation. The VIO bus\nalso tracks the aggregate desired entitlement of all the devices. If the\nsystem desired entitlement is greater than the size of the reserve pool,\nwhen devices unmap IO memory it will be reserved and a balance operation\nwill be scheduled for some time in the future.\n\nEntitlement balancing\n\nThe balance function tries to fairly distribute entitlement between the\ndevices in the system with the goal of providing each device with it\u0027s\ndesired amount of entitlement. Devices using more than what would be\nideal will have their entitled set-point adjusted; this will effectively\nset a goal for lower IO memory usage as future mappings can fail and\ndeallocations will trigger a balance operation to distribute the newly\nunmapped memory. A fair distribution of entitlement can take several\nbalance operations to achieve. Entitlement changes and device DLPAR\nevents will alter the state of CMO and will trigger balance operations.\n\nHotplug events\n\nThe VIO bus allows for changes in system entitlement at run-time via\n\u0027vio_cmo_entitlement_update()\u0027. When devices are added the hotplug\ndevice event will be preceded by a system entitlement increase and this\nis reversed when devices are removed.\n\nThe following changes are made that the VIO bus layer for CMO:\n * add IO memory accounting per device structure.\n * add IO memory entitlement query function to driver structure.\n * during vio bus probe, if CMO is enabled, check that driver has\n memory entitlement query function defined. Fail if function not defined.\n * fail to register driver if io entitlement function not defined.\n * create set of dma_ops at vio level for CMO that will track allocations\n and return DMA failures once entitlement is reached. Entitlement will\n limited by overall system entitlement. Devices will have a reserved\n quantity of memory that is guaranteed, the rest can be used as available.\n * expose entitlement, current allocation, desired allocation, and the\n allocation error counter for devices to the user through sysfs\n * provide mechanism for changing a device\u0027s desired entitlement at run time\n for devices as an exported function and sysfs tunable\n * track any DMA failures for entitled IO memory for each vio device.\n * check entitlement against available system entitlement on device add\n * track entitlement metrics (high water mark, current usage)\n * provide function to reset high water mark\n * provide minimum and desired entitlement numbers at a bus level\n * provide drivers with a minimum guaranteed entitlement\n * balance available entitlement between devices to satisfy their needs\n * handle system entitlement changes and device hotplug\n\nSigned-off-by: Robert Jennings \u003crcj@linux.vnet.ibm.com\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "6490c4903d12f242bec4454301f76f6a7520e399", "tree": "8b4bc5fb45618ed4af993da51985be2e42a39475", "parents": [ "ffa5abbd0c399b32fc13a1b4718d87ee7a716999" ], "author": { "name": "Robert Jennings", "email": "rcj@linux.vnet.ibm.com", "time": "Thu Jul 24 04:31:16 2008 +1000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Jul 25 15:44:43 2008 +1000" }, "message": "powerpc/pseries: iommu enablement for CMO\n\nTo support Cooperative Memory Overcommitment (CMO), we need to check\nfor failure from some of the tce hcalls.\n\nThese changes for the pseries platform affect the powerpc architecture;\npatches for the other affected platforms are included in this patch.\n\npSeries platform IOMMU code changes:\n * platform TCE functions must handle H_NOT_ENOUGH_RESOURCES errors and\n return an error.\n\nArchitecture IOMMU code changes:\n * Calls to ppc_md.tce_build need to check return values and return\n DMA_MAPPING_ERROR for transient errors.\n\nArchitecture changes:\n * struct machdep_calls for tce_build*_pSeriesLP functions need to change\n to indicate failure.\n * all other platforms will need updates to iommu functions to match the new\n calling semantics; they will return 0 on success.

I have defined PROT_SAO to be 0x10.\n\nSigned-off-by: Dave Kleikamp \u003cshaggy@linux.vnet.ibm.com\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "058c78f4ba89df7b2de82ac271452f09e2b8fa05", "tree": "d6c70a7a1b3210daf7102cbad44590d38053f008", "parents": [ "3a4c6f0b1540811110a59112b4c83f55c229728c" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Mon Jul 07 13:44:31 2008 +1000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Jul 09 16:30:44 2008 +1000" }, "message": "powerpc: Use new printk extension %pS to print symbols on oops\n\nThis changes the oops and backtrace code to use the new %pS\nprintk extension to print out symbols rather than manually\ncalling print_symbol.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "3a4c6f0b1540811110a59112b4c83f55c229728c", "tree": "6d2cc36af1100103ceb649a6fbdf8b2a9b526947", "parents": [ "7e5f8105030038de94b44a74cd7b64dd000830fc" ], "author": { "name": "Mark Nelson", "email": "markn@au1.ibm.com", "time": "Sat Jul 05 05:05:45 2008 +1000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Jul 09 16:30:44 2008 +1000" }, "message": "powerpc: move device_to_mask() to dma-mapping.h\n\nMove device_to_mask() to dma-mapping.h because we need to use it from\noutside dma_64.c in a later patch.\n\nSigned-off-by: Mark Nelson \u003cmarkn@au1.ibm.com\u003e\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "3affedc4e1ce837033b6c5e9289d2ce2f5a62d31", "tree": "83296af2c727e5b5f64b88b629dcf37f8e60e3f0", "parents": [ "c8692362db3db3a6f644e05a477161d967430aac" ], "author": { "name": "Mark Nelson", "email": "markn@au1.ibm.com", "time": "Sat Jul 05 05:05:42 2008 +1000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Jul 09 16:30:43 2008 +1000" }, "message": "powerpc/dma: implement new dma_*map*_attrs() interfaces\n\nUpdate powerpc to use the new dma_*map*_attrs() interfaces.
