These IPIs are useful and cannot be avoided\naltogether, but in certain cases it is possible to interrupt only specific\nCPUs that have useful work to do and not the entire system.\n\nThis patch set, inspired by discussions with Peter Zijlstra and Frederic\nWeisbecker when testing the nohz task patch set, is a first stab at trying\nto explore doing this by locating the places where such global IPI calls\nare being made and turning the global IPI into an IPI for a specific group\nof CPUs. The purpose of the patch set is to get feedback if this is the\nright way to go for dealing with this issue and indeed, if the issue is\neven worth dealing with at all. Based on the feedback from this patch set\nI plan to offer further patches that address similar issue in other code\npaths.\n\nThis patch creates an on_each_cpu_mask() and on_each_cpu_cond()\ninfrastructure API (the former derived from existing arch specific\nversions in Tile and Arm) and uses them to turn several global IPI\ninvocation to per CPU group invocations.\n\nCore kernel:\n\non_each_cpu_mask() calls a function on processors specified by cpumask,\nwhich may or may not include the local processor.\n\nYou must not call this function with disabled interrupts or from a\nhardware interrupt handler or from a bottom half handler.\n\narch/arm:\n\nNote that the generic version is a little different then the Arm one:\n\n1. It has the mask as first parameter\n2. It calls the function on the calling CPU with interrupts disabled,\n but this should be OK since the function is called on the other CPUs\n with interrupts disabled anyway.\n\narch/tile:\n\nThe API is the same as the tile private one, but the generic version\nalso calls the function on the with interrupts disabled in UP case\n\nThis is OK since the function is called on the other CPUs\nwith

shmctl(), etc., and\nin the kernel we would want them to be handled directly by\ncompat_sys_xxx() functions, as is true for other compat syscalls.\n\nHowever, for historical reasons, several of the existing compat IPC\nsyscalls do not do this. semctl() expects a pointer to the fourth\nargument, instead of the fourth argument itself. msgsnd(), msgrcv()\nand shmat() expect arguments in different order.\n\nThis change adds an ARCH_WANT_OLD_COMPAT_IPC config option that can be\nset to preserve this behavior for ports that use it (x86, sparc, powerpc,\ns390, and mips). No actual semantics are changed for those architectures,\nand there is only a minimal amount of code refactoring in ipc/compat.c.\n\nNewer architectures like tile (and perhaps future architectures such\nas arm64 and unicore64) should not select this option, and thus can\navoid having any IPC-specific code at all in their architecture-specific\ncompat layer. In the same vein, if this option is not selected, IPC_64\nmode is assumed, since that\u0027s what the \u003casm-generic\u003e headers expect.\n\nThe workaround code in \"tile\" for msgsnd() and msgrcv() is removed\nwith this change; it also fixes the bug that shmat() and semctl() were\nnot being properly handled.\n\nReviewed-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "ad092338350e517608a41341095b6b1e312c4eb1", "tree": "1f2d5273f4e7fc3648f571355bfb7f1f79d796b7", "parents": [ "cf8c1dafe19ae9f855bf7b9cce2e13b26c3289b7" ], "author": { "name": "Matt Fleming", "email": "matt.fleming@intel.com", "time": "Tue Feb 14 11:41:06 2012 +0000" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Tue Mar 13 16:42:05 2012 -0400" }, "message": "tile: Use set_current_blocked() and block_sigmask()\n\nAs described in e6fa16ab (\"signal: sigprocmask() should do\nretarget_shared_pending()\") the modification of current-\u003eblocked is\nincorrect as we need to check whether the signal we\u0027re about to block\nis pending in the shared queue.\n\nAlso, use the new helper function introduced in commit 5e6292c0f28f\n(\"signal: add block_sigmask() for adding sigmask to current-\u003eblocked\")\nwhich centralises the code for updating current-\u003eblocked after\nsuccessfully delivering a signal and reduces the amount of duplicate\ncode across architectures.

Arnd suggested\nlooking at sysfs for that, so this change moves that information\nto a pair of sysfs attributes (chip_width and chip_height) in the\n/sys/devices/system/cpu directory. We also put the \"chip_serial\"\nand \"chip_revision\" information from our old /proc/tile/board file\nas attributes in /sys/devices/system/cpu.\n\nOther information collected via hypervisor APIs is now placed in\n/sys/hypervisor. We create a /sys/hypervisor/type file (holding the\nconstant string \"tilera\") to be parallel with the Xen use of\n/sys/hypervisor/type holding \"xen\". We create three top-level files,\n\"version\" (the hypervisor\u0027s own version), \"config_version\" (the\nversion of the configuration file), and \"hvconfig\" (the contents of\nthe configuration file). The remaining information from our old\n/proc/tile/board and /proc/tile/switch files becomes an attribute\ngroup appearing under /sys/hypervisor/board/.\n\nFinally, after some feedback from Arnd Bergmann for the previous\nversion of this patch, the /proc/tile/hardwall file is split up into\ntwo conceptual parts. First, a directory /proc/tile/hardwall/ which\ncontains one file per active hardwall, each file named after the\nhardwall\u0027s ID and holding a cpulist that says which cpus are enclosed by\nthe hardwall. Second, a /proc/PID file \"hardwall\" that is either\nempty (for non-hardwall-using processes) or contains the hardwall ID.\n\nFinally, this change pushes the /proc/sys/tile/unaligned_fixup/\ndirectory, with knobs controlling the kernel code for handling the\nfixup of unaligned exceptions.\n\nReviewed-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "0798b1dbfbd9ff2a370c5968c5f0621ef0075fe0", "tree": "c7f61ab9683786a070da0933b9981fc74a4d865f", "parents": [ "ad363e0916423b2e6cdfcdc30ae707ec709f0a65", "6738d3210aabe3016a1b03cd98a7fc479c229197" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 15:35:32 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 15:35:32 2011 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: (26 commits)\n arch/tile: prefer \"tilepro\" as the name of the 32-bit architecture\n compat: include aio_abi.h for aio_context_t\n arch/tile: cleanups for tilegx compat mode\n arch/tile: allocate PCI IRQs later in boot\n arch/tile: support signal \"exception-trace\" hook\n arch/tile: use better definitions of xchg() and cmpxchg()\n include/linux/compat.h: coding-style fixes\n tile: add an RTC driver for the Tilera hypervisor\n arch/tile: finish enabling support for TILE-Gx 64-bit chip\n compat: fixes to allow working with tile arch\n arch/tile: update defconfig file to something more useful\n tile: do_hardwall_trap: do not play with task-\u003esighand\n tile: replace mm-\u003ecpu_vm_mask with mm_cpumask()\n tile,mn10300: add device parameter to dma_cache_sync()\n audit: support the \"standard\" \u003casm-generic/unistd.h\u003e\n arch/tile: clarify flush_buffer()/finv_buffer() function names\n arch/tile: kernel-related cleanups from removing static page size\n arch/tile: various header improvements for building drivers\n arch/tile: disable GX prefetcher during cache flush\n arch/tile: tolerate disabling CONFIG_BLK_DEV_INITRD\n ...\n" }, { "commit": "5129df03d0c44b2d5a5f9d7d52f3b079706b9a8f", "tree": "799e309a7db032cb7abe9f0fa910c2989c3fdab5", "parents": [ "4d429480352c63db2228489f0db9fd381cdc3c9c", "6988f20fe04e9ef3aea488cb8ab57fbeb78e12f0" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 24 11:53:42 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue May 24 11:53:42 2011 -0700" }, "message": "Merge branch \u0027for-2.6.40\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu\n\n* \u0027for-2.6.40\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:\n percpu: Unify input section names\n percpu: Avoid extra NOP in percpu_cmpxchg16b_double\n percpu: Cast away printk format warning\n percpu: Always align percpu output section to PAGE_SIZE\n\nFix up fairly trivial conflict in arch/x86/include/asm/percpu.h as per Tejun\n" }, { "commit": "818d8462bb7c717706bcfe994258e2c3710d1fd0", "tree": "d597fe6369a03fdf0b8fc0c940579cbe1efab35e", "parents": [ "f4de51de2edcd26ec77bfc71b1f00b1de5a5dc20" ], "author": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Tue May 17 15:52:22 2011 -0400" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Thu May 19 22:56:13 2011 -0400" }, "message": "arch/tile: cleanups for tilegx compat mode\n\nThese changes make the syscall table line up correctly for\ntilegx compat mode, and remove the stale sys32_fadvise64() function,\nwhich isn\u0027t actually used by any syscall table.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "f4de51de2edcd26ec77bfc71b1f00b1de5a5dc20", "tree": "5d565f18fbb0b0edc82af64d7d98e342a0c1c6d8", "parents": [ "571d76acdab95876aeff869ab6449f826c23aa43" ], "author": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Tue May 17 15:25:21 2011 -0400" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Thu May 19 22:56:05 2011 -0400" }, "message": "arch/tile: allocate PCI IRQs later in boot\n\nThis change became required due to some recent reworking in the\nplatform-independent IRQ code.
