For example two video streams could require 11027 microseconds of isochronous bandwidth per microframe to work28 together.29 30 Through this setting it is possible to raise the limit so that31 the host controller would allow allocating more than 10032 microseconds of periodic bandwidth per microframe.33 34 Beware, non-standard modes are usually not thoroughly tested by35 hardware designers, and the hardware can malfunction when this36 setting differ from default 100.37 38What: /sys/module/*/{coresize,initsize}39Date: Jan 201240KernelVersion: 3.341Contact: Kay Sievers <kay.sievers@vrfy.org>42Description: Module size in bytes.43 44What: /sys/module/*/initstate45Date: Nov 200646KernelVersion: 2.6.1947Contact: Kay Sievers <kay.sievers@vrfy.org>48Description: Show the initialization state(live, coming, going) of49 the module.50 51What: /sys/module/*/taint52Date: Jan 201253KernelVersion: 3.354Contact: Kay Sievers <kay.sievers@vrfy.org>55Description: Module taint flags:56 == =====================57 P proprietary module58 O out-of-tree module59 F force-loaded module60 C staging driver module61 E unsigned module62 == =====================63 64What: /sys/module/grant_table/parameters/free_per_iteration65Date: July 202366KernelVersion: 6.5 but backported to all supported stable branches67Contact: Xen developer discussion <xen-devel@lists.xenproject.org>68Description: Read and write number of grant entries to attempt to free per iteration.69 70 Note: Future versions of Xen and Linux may provide a better71 interface for controlling the rate of deferred grant reclaim72 or may not need it at all.73Users: Qubes OS (https://www.qubes-os.org)74
