python mmap.error : Too many open files. 怎么了?

linux - 如何绕过 Linux "Too Many Arguments"限制

我必须将256Kb的文本作为参数传递给“awssqs”命令,但在命令行中遇到了大约140Kb的限制。itbeensolvedintheLinuxkernelasof2.6.23kernel很多地方都讨论过这个问题.但无法让它工作。我正在使用3.14.48-33.39.amzn1.x86_64这里有一个简单的例子来测试:#!/bin/bashSIZE=1000while[$SIZE-lt300000]doecho"$SIZE"VAR="`head-c$SIZEfoo脚本只是:#!/bin/bashecho-n"$1"|wc-c我的输出是:1170371231961231961296801

Linux 内核 : udelay() returns too early?

我有一个需要微秒延迟的驱动程序。为了创建这种延迟,我的驱动程序使用了内核的udelay函数。具体来说,有一次调用udelay(90):iowrite32(data,addr+DATA_OFFSET);iowrite32(trig,addr+CONTROL_OFFSET);udelay(30);trig|=1;iowrite32(trig,addr+CONTROL_OFFSET);udelay(90);//Thisistheproblematiccall我们的设备存在可靠性问题。经过大量调试,我们将问题追踪到驱动程序在90us之前恢复。(参见下面的“证明”。)我在IntelPentium
