At kexec_prepare time we\n scan the pages and if any overlap our (0, _end[]) range we\n return -ETXTBSY.\n\n On PowerPC 64 systems running in LPAR (logical partitioning)\n mode, only a small region of memory, referred to as the RMO,\n can be accessed in real mode. Since Linux runs with only one\n zone of memory in the memory allocator, and it can be orders of\n magnitude more memory than the RMO, looping until we allocate\n pages in the source region is not feasible. Copying in virtual\n means we don\u0027t have to write a hash table generation and call\n hypervisor to insert translations, instead we rely on the pinned\n kernel linear mapping. The kernel already has move to linked\n location built in, so there is no requirement to load it at 0.\n\n If we want to load something other than a kernel, then a stub\n can be written to copy a linear chunk in real mode.\n\n2) The start entry point gets passed parameters from the kernel.\n Slaves are started at a fixed address after copying code from\n the entry point.\n\n All CPUs get passed their firmware assigned physical id in r3\n (most calling conventions use this register for the first\n argument).\n\n This is used to distinguish each CPU from all other CPUs.\n Since firmware is not around, there is no other way to obtain\n this information other than to pass it somewhere.\n\n A single CPU, referred to here as the master and the one executing\n the kexec call, branches to start with the address of start in r4.\n While this can be calculated, we have to load it through a gpr to\n branch to this point so defining the register this is contained\n in is free. A stack of unspecified size is available at r1\n (also common calling convention).\n\n All remaining running CPUs are sent to start at absolute address\n 0x60 after copying the first 0x100 bytes from start to address 0.\n This convention was chosen because it matches what the kernel\n has been doing itself. (only gpr3 is defined).\n\n Note: This is not quite the convention of the kexec bootblock v2\n in the kernel. A stub has been written to convert between them,\n and we may adjust the kernel in the future to allow this directly\n without any stub.\n\n3) Destination pages can be placed anywhere, even where they\n would not be accessible in real mode. This will allow us to\n place ram disks above the RMO if we choose.\n\nSigned-off-by: Milton Miller \u003cmiltonm@bga.com\u003e\nSigned-off-by: R Sharada \u003csharada@in.ibm.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f4c82d5132b0592f5d6befc5b652cbd4b08f12ff", "tree": "3889ea8eeb4dfa6c995b6dc93574d24c238a6deb", "parents": [ "70765aa4bdb8862a49fcf5b28f3deaf561cf5ae7" ], "author": { "name": "R Sharada", "email": "sharada@in.ibm.com", "time": "Sat Jun 25 14:58:08 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Jun 25 16:24:51 2005 -0700" }, "message": "[PATCH] ppc64 kexec: native hash clear\n\nAdd code to clear the hash table and invalidate the tlb for native (SMP,\nnon-LPAR) mode.

And\nI have added ppc_md.machine_crash_shutdown. To keep up with\nthe changes in the generic kexec infrastructure.\n\nFrom: Albert Herranz \u003calbert_herranz@yahoo.es\u003e\n\nThe following patch adds support for kexec on the ppc32 platform.\n\nNon-OpenFirmware based platforms are likely to work directly without\nadditional changes on the kernel side. The kexec-tools userland package\nmay need to be slightly updated, though.\n\nFor OpenFirmware based machines, additional work is still needed on the\nkernel side before kexec support is ready. Benjamin Herrenschmidt is\nkindly working on that part.\n\nIn order for a ppc platform to use the kexec kernel services it must\nimplement some ppc_md hooks. Otherwise, kexec will be explicitly disabled,\nas suggested by benh.\n\nThere are 3+1 new ppc_md hooks that a platform supporting kexec may\nimplement. Two of them are mandatory for kexec to work. See\ninclude/asm-ppc/machdep.h for details.\n\n- machine_kexec_prepare(image)\n\n This function is called to make any arrangements to the image before it\n is loaded.\n\n This hook _MUST_ be provided by a platform in order to activate kexec\n support for that platform. Otherwise, the platform is considered to not\n support kexec and the kexec_load system call will fail (that makes all\n existing platforms by default non-kexec\u0027able).\n\n- machine_kexec_cleanup(image)\n\n This function is called to make any cleanups on image after the loaded\n image data it is freed. This hook is optional. A platform may or may\n not provide this hook.\n\n- machine_kexec(image)\n\n This function is called to perform the _actual_ kexec. This hook\n _MUST_ be provided by a platform in order to activate kexec support for\n that platform.\n\n If a platform provides machine_kexec_prepare but forgets to provide\n machine_kexec, a kexec will fall back to a reboot.\n\n A ready-to-use machine_kexec_simple() generic function is provided to,\n hopefully, simplify kexec adoption for embedded platforms. A platform\n may call this function from its specific machine_kexec hook, like this:\n\nvoid myplatform_kexec(struct kimage *image)\n{\n machine_kexec_simple(image);\n}\n\n- machine_shutdown()\n\n This function is called to perform any machine specific shutdowns, not\n already done by drivers. This hook is optional. A platform may or may\n not provide this hook.\n\nAn example (trimmed) platform specific module for a platform supporting\nkexec through the existing machine_kexec_simple follows:\n\n/* ... */\n\n#ifdef CONFIG_KEXEC\nint myplatform_kexec_prepare(struct kimage *image)\n{\n /* here, we can place additional preparations\n*/\n return 0; /* yes, we support kexec */\n}\n\nvoid myplatform_kexec(struct kimage *image)\n{\n machine_kexec_simple(image);\n}\n#endif /* CONFIG_KEXEC */\n\n/* ... */\n\nvoid __init\nplatform_init(unsigned long r3, unsigned long r4,\nunsigned long r5,\n unsigned long r6, unsigned long r7)\n{\n\n/* ... */\n\n#ifdef CONFIG_KEXEC\n ppc_md.machine_kexec_prepare \u003d\nmyplatform_kexec_prepare;\n ppc_md.machine_kexec \u003d\nmyplatform_kexec;\n#endif /* CONFIG_KEXEC */\n\n/* ... */\n\n}\n\nThe kexec ppc kernel support has been heavily tested on the GameCube Linux\nport, and, as reported in the fastboot mailing list, it has been tested too\non a Moto 82xx ppc by Rick Richardson.\n\nSigned-off-by: Albert Herranz \u003calbert_herranz@yahoo.es\u003e\nSigned-off-by: Eric Biederman \u003cebiederm@xmission.com\u003e\nAcked-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "5f5609df0c943b005847d3b2765d6dd47b624011", "tree": "f994509dc8b507b9392bcf632c4df2a0261a9f5f", "parents": [ "5234f5eb04abbbfa306ccfbc2ccbb6e73f515b15" ], "author": { "name": "Eric W.

Now the trace buffers are subdivided into several\nsubbuffers with pagesize. Therefore it is now possible to allocate more\nmemory for the trace buffers and more trace records can be written.\n\nIn addition to that, dynamic specification of the size of the trace buffers is\nimplemented. It is now possible to change the size of a trace buffer using a\nnew debugfs file instance. When writing a number into this file, the trace\nbuffer size is changed to \u0027number * pagesize\u0027.\n\nIn the past all the traces could be obtained from userspace by accessing files\nin the \"proc\" filesystem. Now with debugfs we have a new filesystem which\nshould be used for debugging purposes.
