For example two video streams could require 110 27*4882a593Smuzhiyun microseconds of isochronous bandwidth per microframe to work 28*4882a593Smuzhiyun together. 29*4882a593Smuzhiyun 30*4882a593Smuzhiyun Through this setting it is possible to raise the limit so that 31*4882a593Smuzhiyun the host controller would allow allocating more than 100 32*4882a593Smuzhiyun microseconds of periodic bandwidth per microframe. 33*4882a593Smuzhiyun 34*4882a593Smuzhiyun Beware, non-standard modes are usually not thoroughly tested by 35*4882a593Smuzhiyun hardware designers, and the hardware can malfunction when this 36*4882a593Smuzhiyun setting differ from default 100. 37*4882a593Smuzhiyun 38*4882a593SmuzhiyunWhat: /sys/module/*/{coresize,initsize} 39*4882a593SmuzhiyunDate: Jan 2012 40*4882a593SmuzhiyunKernelVersion:»·3.3 41*4882a593SmuzhiyunContact: Kay Sievers <kay.sievers@vrfy.org> 42*4882a593SmuzhiyunDescription: Module size in bytes. 43*4882a593Smuzhiyun 44*4882a593SmuzhiyunWhat: /sys/module/*/taint 45*4882a593SmuzhiyunDate: Jan 2012 46*4882a593SmuzhiyunKernelVersion:»·3.3 47*4882a593SmuzhiyunContact: Kay Sievers <kay.sievers@vrfy.org> 48*4882a593SmuzhiyunDescription: Module taint flags: 49*4882a593Smuzhiyun == ===================== 50*4882a593Smuzhiyun P proprietary module 51*4882a593Smuzhiyun O out-of-tree module 52*4882a593Smuzhiyun F force-loaded module 53*4882a593Smuzhiyun C staging driver module 54*4882a593Smuzhiyun E unsigned module 55*4882a593Smuzhiyun == ===================== 56
