On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386.

SRCU is as follows:\n\no\tEach use of SRCU creates its own srcu_struct, and each\n\tsrcu_struct has its own set of grace periods. This is\n\tcritical, as it prevents one subsystem with a blocking\n\treader from holding up SRCU grace periods for other\n\tsubsystems.\n\no\tThe SRCU primitives (srcu_read_lock(), srcu_read_unlock(),\n\tand synchronize_srcu()) all take a pointer to a srcu_struct.\n\no\tThe SRCU primitives must be called from process context.\n\no\tsrcu_read_lock() returns an int that must be passed to\n\tthe matching srcu_read_unlock(). Realtime RCU avoids the\n\tneed for this by storing the state in the task struct,\n\tbut SRCU needs to allow a given code path to pass through\n\tmultiple SRCU domains -- storing state in the task struct\n\twould therefore require either arbitrary space in the\n\ttask struct or arbitrary limits on SRCU nesting. So I\n\tkicked the state-storage problem up to the caller.\n\n\tOf course, it is not permitted to call synchronize_srcu()\n\twhile in an SRCU read-side critical section.\n\no\tThere is no call_srcu(). It would not be hard to implement\n\tone, but it seems like too easy a way to OOM the system.\n\t(Hey, we have enough trouble with call_rcu(), which does\n\t-not- permit readers to sleep!!!)

The two big issues I address are an artificially\nsmall cap on the number of irqs, and that MSI assumes vector \u003d\u003d irq. My\nprimary focus is on x86_64 but I have touched other architectures where\nnecessary to keep them from breaking.\n\n- To increase the number of irqs I modify the code to look at the (cpu,\n vector) pair instead of just looking at the vector.\n\n With a large number of irqs available systems with a large irq count no\n longer need to compress their irq numbers to fit. Removing a lot of brittle\n special cases.\n\n For acpi guys the result is that irq \u003d\u003d gsi.\n\n- Addressing the fact that MSI assumes irq \u003d\u003d vector takes a few more\n patches. But suffice it to say when I am done none of the generic irq code\n even knows what a vector is.\n\nIn quick testing on a large Unisys x86_64 machine we stumbled over at least\none driver that assumed that NR_IRQS could always fit into an 8 bit number.\nThis driver is clearly buggy today.

In practice I don\u0027t think this has any\naffect because of our alignment constraints and the other fields but there is\nnot point in chewing up an uncessary word and since we already read the flag\nfield this should improve the cache hit ratio of the irq handler.\n\nSigned-off-by: Eric W.

For this race to trigger the process that proc_pid_readdir stops at\nmust exit before readdir is called again.\n\nThis can cause ps to fail to report processes, and it is in violation of\nposix guarantees and normal application expectations with respect to\nreaddir.\n\nCurrently there is no way to work around this problem in user space short\nof providing a gargantuan buffer to user space so the directory read all\nhappens in on system call.\n\nThis patch implements the normal directory semantics for proc, that\nguarantee that a directory entry that is neither created nor destroyed\nwhile reading the directory entry will be returned. For directory that are\neither created or destroyed during the readdir you may or may not see them.\n Furthermore you may seek to a directory offset you have previously seen.\n\nThese are the guarantee that ext[23] provides and that posix requires, and\nmore importantly that user space expects. Plus it is a simple semantic to\nimplement reliable service. It is just a matter of calling readdir a\nsecond time if you are wondering if something new has show up.\n\nThese better semantics are implemented by scanning through the pids in\nnumerical order and by making the file offset a pid plus a fixed offset.\n\nThe pid scan happens on the pid bitmap, which when you look at it is\nremarkably efficient for a brute force algorithm. Given that a typical\ncache line is 64 bytes and thus covers space for 64*8 \u003d\u003d 200 pids. There\nare only 40 cache lines for the entire 32K pid space. A typical system\nwill have 100 pids or more so this is actually fewer cache lines we have to\nlook at to scan a linked list, and the worst case of having to scan the\nentire pid bitmap is pretty reasonable.\n\nIf we need something more efficient we can go to a more efficient data\nstructure for indexing the pids, but for now what we have should be\nsufficient.\n\nIn addition this takes no additional locks and is actually less code than\nwhat we are doing now.\n\nAlso another very subtle bug in this area has been fixed. It is possible\nto catch a task in the middle of de_thread where a thread is assuming the\nthread of it\u0027s thread group leader. This patch carefully handles that case\nso if we hit it we don\u0027t fail to return the pid, that is undergoing the\nde_thread dance.\n\nThanks to KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e for\nproviding the first fix, pointing this out and working on it.\n\n[oleg@tv-sign.ru: fix it]\nSigned-off-by: Eric W.

I ran out of time before doing that though.\n\nThe demo prototype scripts weren\u0027t very good. If there is really interest I\ncan dig them out (they are currently on a laptop disk on the desk with the\nlaptop itself being in service), but I would recommend to rewrite them for any\nserious application of this and fix the disk space problem.\n\nAlso to be really useful it should probably find a way to automatically fetch\nthe debuginfos (I cheated and just installed them in advance). If nobody else\ndoes it I can probably do the rewrite myself again at some point.\n\nMy hope at some point was that desktops would support it in their builtin\ncrash reporters, but at least the KDE people I talked too seemed to be happy\nwith their user space only solution.\n\nAlan sayeth:\n\n I don\u0027t believe that piping as such as neccessarily the right model, but\n the ability to intercept and processes core dumps from user space is asked\n for by many enterprise users as well.
