And cleans up the variable-name\nand function-name language. ;-)\n\nThe boot CPU runs in the context of its idle thread during boot-up.\nDuring this time, idle_cpu(0) will always return nonzero, which will\nfool Classic and Hierarchical RCU into deciding that a large chunk of\nthe boot-up sequence is a big long quiescent state. This in turn causes\nRCU to prematurely end grace periods during this time.\n\nThis patch changes the rcutree.c and rcuclassic.c rcu_check_callbacks()\nfunction to ignore the idle task as a quiescent state until the\nsystem has started up the scheduler in rest_init(), introducing a\nnew non-API function rcu_idle_now_means_idle() to inform RCU of this\ntransition. RCU maintains an internal rcu_idle_cpu_truthful variable\nto track this state, which is then used by rcu_check_callback() to\ndetermine if it should believe idle_cpu().\n\nBecause this patch has the effect of disallowing RCU grace periods\nduring long stretches of the boot-up sequence, this patch also introduces\nJosh Triplett\u0027s UP-only optimization that makes synchronize_rcu() be a\nno-op if num_online_cpus() returns 1. This allows boot-time code that\ncalls synchronize_rcu() to proceed normally. Note, however, that RCU\ncallbacks registered by call_rcu() will likely queue up until later in\nthe boot sequence. Although rcuclassic and rcutree can also use this\nsame optimization after boot completes, rcupreempt must restrict its\nuse of this optimization to the portion of the boot sequence before the\nscheduler starts up, given that an rcupreempt RCU read-side critical\nsection may be preeempted.\n\nIn addition, this patch takes Nick Piggin\u0027s suggestion to make the\nsystem_state global variable be __read_mostly.\n\nChanges since v4:\n\no\tChanges the name of the introduced function and variable to\n\tbe less emotional. ;-)\n\nChanges since v3:\n\no\tWARN_ON(nr_context_switches() \u003e 0) to verify that RCU\n\tswitches out of boot-time mode before the first context\n\tswitch, as suggested by Nick Piggin.\n\nChanges since v2:\n\no\tCreated rcu_blocking_is_gp() internal-to-RCU API that\n\tdetermines whether a call to synchronize_rcu() is itself\n\ta grace period.\n\no\tThe definition of rcu_blocking_is_gp() for rcuclassic and\n\trcutree checks to see if but a single CPU is online.\n\no\tThe definition of rcu_blocking_is_gp() for rcupreempt\n\tchecks to see both if but a single CPU is online and if\n\tthe system is still in early boot.\n\n\tThis allows rcupreempt to again work correctly if running\n\ton a single CPU after booting is complete.\n\no\tAdded check to rcupreempt\u0027s synchronize_sched() for there\n\tbeing but one online CPU.\n\nTested all three variants both SMP and !SMP, booted fine, passed a short\nrcutorture test on both x86 and Power.\n\nLocated-by: Vegard Nossum \u003cvegard.nossum@gmail.com\u003e\nTested-by: Vegard Nossum \u003cvegard.nossum@gmail.com\u003e\nTested-by: Paul E.

However, this emulation is not perfect, as\nalso noticed on changeset 7500b1f602aad75901774a67a687ee985d85893f.\n\nBefore this patch, the kernel were trying to check if the serial TX is\ncapable of work using IRQ\u0027s.\n\nThis were done with a code similar this:\n\n serial_outp(up, UART_IER, UART_IER_THRI);\n lsr \u003d serial_in(up, UART_LSR);\n iir \u003d serial_in(up, UART_IIR);\n serial_outp(up, UART_IER, 0);\n\n if (lsr \u0026 UART_LSR_TEMT \u0026\u0026 iir \u0026 UART_IIR_NO_INT)\n\t\tup-\u003ebugs |\u003d UART_BUG_TXEN;\n\nThis works fine for other 8250 ports, but, on 8250-emulated SoL port, the\nchip is a little lazy to down UART_IIR_NO_INT at UART_IIR register.\n\nDue to that, UART_BUG_TXEN is sometimes enabled. However, as TX IRQ keeps\nworking, and the TX polling is now enabled, the driver miss-interprets the\nIRQ received later, hanging up the machine until a key is pressed at the\nserial console.\n\nThis is the 6 version of this patch. Previous versions were trying to\nintroduce a large enough delay between serial_outp and serial_in(up,\nUART_IIR), but not taking forever. However, the needed delay couldn\u0027t be\nsafely determined.\n\nAt the experimental tests, a delay of 1us solves most of the cases, but\nstill hangs sometimes. Increasing the delay to 5us was better, but still\ndoesn\u0027t solve. A very high delay of 50 ms seemed to work every time.\n\nHowever, poking around with delays and pray for it to be enough doesn\u0027t\nseem to be a good approach, even for a quirk.\n\nSo, instead of playing with random large arbitrary delays, let\u0027s just\ndisable UART_BUG_TXEN for all SoL ports.\n\n[akpm@linux-foundation.org: fix warnings]\nSigned-off-by: Mauro Carvalho Chehab

The dynamic function trace\nallows you to pick and choose which of those functions will be\ntraced, but all functions being traced will call all tracers that\nregistered with the function tracer.\n\nThis patch adds a new feature that allows a tracer to hook to specific\nfunctions, even when all functions are being traced. It allows for\ndifferent functions to call different tracer hooks.\n\nThe way this is accomplished is by a special function that will hook\nto the function tracer and will set up a hash table knowing which\ntracer hook to call with which function. This is the most general\nand easiest method to accomplish this. Later, an arch may choose\nto supply their own method in changing the mcount call of a function\nto call a different tracer. But that will be an exercise for the\nfuture.\n\nTo register a function:\n\n struct ftrace_hook_ops {\n\tvoid\t\t\t(*func)(unsigned long ip,\n\t\t\t\t\tunsigned long parent_ip,\n\t\t\t\t\tvoid **data);\n\tint\t\t\t(*callback)(unsigned long ip, void **data);\n\tvoid\t\t\t(*free)(void **data);\n };\n\n int register_ftrace_function_hook(char *glob, struct ftrace_hook_ops *ops,\n\t\t\t\t void *data);\n\nglob is a simple glob to search for the functions to hook.\nops is a pointer to the operations (listed below)\ndata is the default data to be passed to the hook functions when traced\n\nops:\n func is the hook function to call when the functions are traced\n callback is a callback function that is called when setting up the hash.\n That is, if the tracer needs to do something special for each\n function, that is being traced, and wants to give each function\n its own data. The address of the entry data is passed to this\n callback, so that the callback may wish to update the entry to\n whatever it would like.\n free is a callback for when the entry is freed. In case the tracer\n allocated any data, it is give the chance to free it.\n\nTo unregister we have three functions:\n\n void\n unregister_ftrace_function_hook(char *glob, struct ftrace_hook_ops *ops,\n\t\t\t\tvoid *data)\n\nThis will unregister all hooks that match glob, point to ops, and\nhave its data matching data. (note, if glob is NULL, blank or \u0027*\u0027,\nall functions will be tested).\n\n void\n unregister_ftrace_function_hook_func(char *glob,\n\t\t\t\t struct ftrace_hook_ops *ops)\n\nThis will unregister all functions matching glob that has an entry\npointing to ops.\n\n void unregister_ftrace_function_hook_all(char *glob)\n\nThis simply unregisters all funcs.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\n" }, { "commit": "f6180773d90595650e11de0118bb112018290915", "tree": "ccf8642d7ac584f73e7820fae64fc4daf4546f6b", "parents": [ "e68746a271eb3393a2183840be9e903caddf765b" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Sat Feb 14 00:40:25 2009 -0500" }, "committer": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Mon Feb 16 17:06:02 2009 -0500" }, "message": "ftrace: add command interface for function selection\n\nAllow for other tracers to add their own commands for function\nselection.

This is\ndue to the hardirq_count being a mask that can hold NR_IRQS.\n\nSome archs allow for over 16000 IRQs, and that would require a mask\nof 14 bits. The sofitrq mask is 8 bits and the preempt disable mask\nis also 8 bits. The PREEMP_ACTIVE bit is bit 30, and bit 31 would\nmake the preempt_count (which is type int) a negative number.\nA negative preempt_count is a sign of failure.\n\nAdd them up 14+8+8+1+1 you get 32 bits. No room for the NMI bit.\n\nBut the hardirq_count is to track the number of nested IRQs, not\nthe number of total IRQs. This originally took the paranoid approach\nof setting the max nesting to NR_IRQS. But when we have archs with\nover 1000 IRQs, it is not practical to think they will ever all\nnest on a single CPU. Not to mention that this would most definitely\ncause a stack overflow.\n\nThis patch sets a max of 10 bits to be used for IRQ nesting.\nI did a \u0027git grep HARDIRQ\u0027 to examine all users of HARDIRQ_BITS and\nHARDIRQ_MASK, and found that making it a max of 10 would not hurt\nanyone. I did find that the m68k expected it to be 8 bits, so\nI allow for the archs to set the number to be less than 10.\n\nI removed the setting of HARDIRQ_BITS from the archs that set it\nto more than 10. This includes ALPHA, ia64 and avr32.\n\nThis will always allow room for the NMI bit, and if we need to allow\nfor NMI nesting, we have 4 bits to play with.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\n" }, { "commit": "6c5979631b4b03c9288776562c18036765e398c1", "tree": "00b7546bc54658b3d1d166b75eb1e498b3ee8475", "parents": [ "0e4a9b59282914fe057ab17027f55123964bc2e2" ], "author": { "name": "Heiko Carstens", "email": "heiko.carstens@de.ibm.com", "time": "Wed Feb 11 13:04:38 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Feb 11 14:25:36 2009 -0800" }, "message": "syscall define: fix uml compile bug\n\nWith the new system call defines we get this on uml:\n\narch/um/sys-i386/built-in.o: In function `sys_call_table\u0027:\n(.rodata+0x308): undefined reference to `sys_sigprocmask\u0027\n\nReason for this is that uml passes the preprocessor option\n-Dsigprocmask\u003dkernel_sigprocmask to gcc when compiling the kernel.\nThis causes SYSCALL_DEFINE3(sigprocmask, ...) to be expanded to\nSYSCALL_DEFINEx(3, kernel_sigprocmask, ...) and finally to a system\ncall named sys_kernel_sigprocmask.
