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.

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.

When a writer crosses a page, it grabs a per cpu spinlock\nto protect against a reader. The spinlocks taken by a writer are not\nto protect against other writers, since a writer can only write to\nits own per cpu buffer. The spinlocks protect against readers that\ncan touch any cpu buffer. The writers are made to be reentrant\nwith the spinlocks disabling interrupts.\n\nThe problem arises when an NMI writes to the buffer, and that write\ncrosses a page boundary. If it grabs a spinlock, it can be racing\nwith another writer (since disabling interrupts does not protect\nagainst NMIs) or with a reader on the same CPU. Luckily, most of the\nusers are not reentrant and protects against this issue. But if a\nuser of the ring buffer becomes reentrant (which is what the ring\nbuffers do allow), if the NMI also writes to the ring buffer then\nwe risk the chance of a deadlock.\n\nThis patch moves the ftrace_nmi_enter called by nmi_enter() to the\nring buffer code. It replaces the current ftrace_nmi_enter that is\nused by arch specific code to arch_ftrace_nmi_enter and updates\nthe Kconfig to handle it.\n\nWhen an NMI is called, it will set a per cpu variable in the ring buffer\ncode and will clear it when the NMI exits. If a write to the ring buffer\ncrosses page boundaries inside an NMI, a trylock is used on the spin\nlock instead. If the spinlock fails to be acquired, then the entry\nis discarded.\n\nThis bug appeared in the ftrace work in the RT tree, where event tracing\nis reentrant. This workaround solved the deadlocks that appeared there.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\n" }, { "commit": "e83102cab0fd95d4508361b061146c978b3abd60", "tree": "d1452292bf5d55da6a072d36d507d2e918ee2180", "parents": [ "7f9a50a5b89b87f8e754f59ae9968da28be618a5", "5294e256717923f4a3297bb8b802f5e0625763f3" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Feb 07 10:46:30 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Feb 07 10:46:30 2009 -0800" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6:\n PCI PM: make the PM core more careful with drivers using the new PM framework\n PCI PM: Read power state from device after trying to change it on resume\n PCI PM: Do not disable and enable bridges during suspend-resume\n PCI: PCIe portdrv: Simplify suspend and resume\n PCI PM: Fix saving of device state in pci_legacy_suspend\n PCI PM: Check if the state has been saved before trying to restore it\n PCI PM: Fix handling of devices without drivers\n PCI: return error on failure to read PCI ROMs\n PCI: properly clean up ASPM link state on device remove\n" }, { "commit": "7f9a50a5b89b87f8e754f59ae9968da28be618a5", "tree": "fd3baa0d66b14a6d5adc4f09088fa15dfcb5b7ab", "parents": [ "f12b12a8aecfcafcf2f9df1c1658d2484959dfda" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Sat Feb 07 18:15:56 2009 +1030" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Feb 07 08:33:01 2009 -0800" }, "message": "module: remove over-zealous check in __module_get()\n\nImpact: fix spurious BUG_ON() triggered under load\n\nmodule_refcount() isn\u0027t reliable outside stop_machine(), as demonstrated\nby Karsten Keil \u003ckkeil@suse.de\u003e, networking can trigger it under load\n(an inc on one cpu and dec on another while module_refcount() is tallying\n can give false results, for example).\n\nAlmost noone should be using __module_get, but that\u0027s another issue.\n\nCc: Karsten Keil \u003ckkeil@suse.de\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "2d29c6a075787f2c1bc49b86a084d2b878f72fc4" }
