There are three forms of the advice:\n\n1) Burst as much as possible, it is not necessary to end bursts\n on some particular boundary for best performance.\n\n2) Burst on some byte count multiple. A DMA burst to some multiple of\n number of bytes may be done, but it is important to end the burst\n on an exact multiple for best performance.\n\n The best example of this I am aware of are the PPC64 PCI\n controllers, where if you end a burst mid-cacheline then\n chip has to refetch the data and the IOMMU translations\n which hurts performance a lot.\n\n3) Burst on a single byte count multiple. Bursts shall end\n exactly on the next multiple boundary for best performance.\n\n Sparc64 and Alpha\u0027s PCI controllers operate this way. They\n disconnect any device which tries to burst across a cacheline\n boundary.\n\n Actually, newer sparc64 PCI controllers do not have this behavior.\n That is why the \"pdev\" is passed into the interface, so I can\n add code later to check which PCI controller the system is using\n and give advice accordingly.\n\nSigned-off-by: David S.

This enables you to establish a handler to be run when a\nfunction returns.\n\n1. API\n\nTwo new functions are added to kprobes:\n\n\tint register_kretprobe(struct kretprobe *rp);\n\tvoid unregister_kretprobe(struct kretprobe *rp);\n\n2. Registration and unregistration\n\n2.1 Register\n\n To register a function-return probe, the user populates the following\n fields in a kretprobe object and calls register_kretprobe() with the\n kretprobe address as an argument:\n\n kp.addr - the function\u0027s address\n\n handler - this function is run after the ret instruction executes, but\n before control returns to the return address in the caller.\n\n maxactive - The maximum number of instances of the probed function that\n can be active concurrently. For example, if the function is non-\n recursive and is called with a spinlock or mutex held, maxactive \u003d 1\n should be enough. If the function is non-recursive and can never\n relinquish the CPU (e.g., via a semaphore or preemption), NR_CPUS should\n be enough. maxactive is used to determine how many kretprobe_instance\n objects to allocate for this particular probed function. If maxactive \u003c\u003d\n 0, it is set to a default value (if CONFIG_PREEMPT maxactive\u003dmax(10, 2 *\n NR_CPUS) else maxactive\u003dNR_CPUS)\n\n For example:\n\n struct kretprobe rp;\n rp.kp.addr \u003d /* entrypoint address */\n rp.handler \u003d /*return probe handler */\n rp.maxactive \u003d /* e.g., 1 or NR_CPUS or 0, see the above explanation */\n register_kretprobe(\u0026rp);\n\n The following field may also be of interest:\n\n nmissed - Initialized to zero when the function-return probe is\n registered, and incremented every time the probed function is entered but\n there is no kretprobe_instance object available for establishing the\n function-return probe (i.e., because maxactive was set too low).\n\n2.2 Unregister\n\n To unregiter a function-return probe, the user calls\n unregister_kretprobe() with the same kretprobe object as registered\n previously. If a probed function is running when the return probe is\n unregistered, the function will return as expected, but the handler won\u0027t\n be run.\n\n3. Limitations\n\n3.1 This patch supports only the i386 architecture, but patches for\n x86_64 and ppc64 are anticipated soon.\n\n3.2 Return probes operates by replacing the return address in the stack\n (or in a known register, such as the lr register for ppc). This may\n cause __builtin_return_address(0), when invoked from the return-probed\n function, to return the address of the return-probes trampoline.\n\n3.3 This implementation uses the \"Multiprobes at an address\" feature in\n 2.6.12-rc3-mm3.\n\n3.4 Due to a limitation in multi-probes, you cannot currently establish\n a return probe and a jprobe on the same function. A patch to remove\n this limitation is being tested.\n\nThis feature is required by SystemTap (http://sourceware.org/systemtap),\nand reflects ideas contributed by several SystemTap developers, including\nWill Cohen and Ananth Mavinakayanahalli.\n\nSigned-off-by: Hien Nguyen \u003chien@us.ibm.com\u003e\nSigned-off-by: Prasanna S Panchamukhi \u003cprasanna@in.ibm.com\u003e\nSigned-off-by: Frederik Deweerdt \u003cfrederik.deweerdt@laposte.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "dcd497f99a1ef29a7c5e76142965be77e9dacabd", "tree": "684d64753c6cd71917cf3c360023dd273be376b4", "parents": [ "35a82d1a53e1a9ad54efafcc940f9335beaed5c3" ], "author": { "name": "Jesper Juhl", "email": "juhl-lkml@dif.dk", "time": "Thu Jun 23 00:09:07 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:19 2005 -0700" }, "message": "[PATCH] streamline preempt_count type across archs\n\nThe preempt_count member of struct thread_info is currently either defined\nas int, unsigned int or __s32 depending on arch.

This could\nlead to potential kernel panic(). This issue is becoming more visible with 2.6\nkernel (as default HZ is 1000) and on platforms with higher SMI handling\nlatencies. During the boot time, SMIs are mostly used by BIOS (for things\nlike legacy keyboard emulation).\n\nDescription:\nThe psuedocode for current delay calibration with tsc based delay looks like\n(0) Estimate a value for loops_per_jiffy\n(1) While (loops_per_jiffy estimate is accurate enough)\n(2) wait for jiffy transition (jiffy1)\n(3) Note down current tsc (tsc1)\n(4) loop until tsc becomes tsc1 + loops_per_jiffy\n(5) check whether jiffy changed since jiffy1 or not and refine\nloops_per_jiffy estimate\n\nConsider the following cases\nCase 1:\nIf SMIs happen between (2) and (3) above, we can end up with a\nloops_per_jiffy value that is too low. This results in shorted delays and\nkernel can panic () during boot (Mostly at IOAPIC timer initialization\ntimer_irq_works() as we don\u0027t have enough timer interrupts in a specified\ninterval).\n\nCase 2:\nIf SMIs happen between (3) and (4) above, then we can end up with a\nloops_per_jiffy value that is too high. And with current i386 code, too\nhigh lpj value (greater than 17M) can result in a overflow in\ndelay.c:__const_udelay() again resulting in shorter delay and panic().\n\nSolution:\nThe patch below makes the calibration routine aware of asynchronous events\nlike SMIs. We increase the delay calibration time and also identify any\nsignificant errors (greater than 12.5%) in the calibration and notify it to\nuser.\n\nPatch below changes both i386 and x86-64 architectures to use this\nnew and improved calibrate_delay_direct() routine.\n\nSigned-off-by: Venkatesh Pallipadi \u003cvenkatesh.pallipadi@intel.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "05b79bdcb48c18cd9b580c39e3efb9a1ab078151", "tree": "1767aaa7a4621ff4cf1a85c2078229de54272f30", "parents": [ "d41dee369bff3b9dcb6328d4d822926c28cc2594" ], "author": { "name": "Andy Whitcroft", "email": "apw@shadowen.org", "time": "Thu Jun 23 00:07:57 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:05 2005 -0700" }, "message": "[PATCH] sparsemem memory model for i386\n\nProvide the architecture specific implementation for SPARSEMEM for i386 SMP\nand NUMA systems.\n\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nSigned-off-by: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nSigned-off-by: Martin Bligh \u003cmbligh@aracnet.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b159d43fbf7eaaac6ecc647f51cf4257332db47b", "tree": "968d856c1bd80b47c76d27da272d95bcaf97aa78", "parents": [ "368a0a3afad08069b2679ecaff80fc18c10a6e2a" ], "author": { "name": "Andy Whitcroft", "email": "apw@shadowen.org", "time": "Thu Jun 23 00:07:52 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:04 2005 -0700" }, "message": "[PATCH] generify early_pfn_to_nid\n\nProvide a default implementation for early_pfn_to_nid returning node 0.

The goal of this\npatch is to reclaim some easily-freed pages from a zone before falling back\nonto another zone.\n\nOne of the major uses of this is NUMA machines. With the default allocator\nbehavior the allocator would look for memory in another zone, which might be\noff-node, before trying to reclaim from the current zone.\n\nThis adds a zone tuneable to enable early zone reclaim. It is selected on a\nper-zone basis and is turned on/off via syscall.\n\nAdding some extra throttling on the reclaim was also required (patch\n4/4).
