When the knfsd bottom half\nis made aware of an incoming call by the socket layer, it tries to\nchoose an nfsd thread and wake it up. As long as there are idle\nthreads, one will be woken up.\n\nIf there are lot of nfsd threads (a sensible configuration when\nthe server is disk-bound or is running an HSM), there will be many\nmore nfsd threads than CPUs to run them. Under a high call-rate\nlow service-time workload, the result is that almost every nfsd is\nrunnable, but only a handful are actually able to run. This situation\ncauses two significant problems:\n\n1. The CPU scheduler takes over 10% of each CPU, which is robbing\n the nfsd threads of valuable CPU time.\n\n2. At a high enough load, the nfsd threads starve userspace threads\n of CPU time, to the point where daemons like portmap and rpc.mountd\n do not schedule for tens of seconds at a time. Clients attempting\n to mount an NFS filesystem timeout at the very first step (opening\n a TCP connection to portmap) because portmap cannot wake up from\n select() and call accept() in time.\n\nDisclaimer: these effects were observed on a SLES9 kernel, modern\nkernels\u0027 schedulers may behave more gracefully.\n\nThe solution is simple: keep in each svc_pool a counter of the number\nof threads which have been woken but have not yet run, and do not wake\nany more if that count reaches an arbitrary small threshold.\n\nTesting was on a 4 CPU 4 NIC Altix using 4 IRIX clients, each with 16\nsynthetic client threads simulating an rsync (i.e. recursive directory\nlisting) workload reading from an i386 RH9 install image (161480\nregular files in 10841 directories) on the server. That tree is small\nenough to fill in the server\u0027s RAM so no disk traffic was involved.\nThis setup gives a sustained call rate in excess of 60000 calls/sec\nbefore being CPU-bound on the server. The server was running 128 nfsds.\n\nProfiling showed schedule() taking 6.7% of every CPU, and __wake_up()\ntaking 5.2%. This patch drops those contributions to 3.0% and 2.2%.\nLoad average was over 120 before the patch, and 20.9 after.\n\nThis patch is a forward-ported version of knfsd-avoid-nfsd-overload\nwhich has been shipping in the SGI \"Enhanced NFS\" product since 2006.\nIt has been posted before:\n\nhttp://article.gmane.org/gmane.linux.nfs/10374\n\nSigned-off-by: Greg Banks \u003cgnb@sgi.com\u003e\nSigned-off-by: J.

The nfs client does have retry logic for\nshort writes, but this is never called as the client is told the\ncomplete write succeeded.\n\nThere are probably other ways it could happen, but in my case it\nhappened with a fuse (filesystem in userspace) filesystem which can\nrather easily have a partial write.\n\nHere is a patch to properly return the short write count to the\nclient.\n\nSigned-off-by: David Shaw \u003cdshaw@jabberwocky.com\u003e\nSigned-off-by: J.

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.

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.
