drivers/ide The IDE family of device drivers used to live indrivers/blockbut has expanded to the point where they were moved into a separate directory. As a matter of fact, the IDE interface has been enhanced and extended over time in order to support more than just conventional hard disks...
3GPP protocol implementation requires deterministic timing to slot and symbol boundaries, whereas Linux has been built to be a general-purpose operating system, not optimized for real time. There are a few different ways of tackling the OS latency topic in real time scheduling environments: • Co...

This change “mt76: mt76x0u: do not reset radio on resume” (commit e064466) in Linux kernel is authored by Stanislaw Gruszka on Wed Sep 4 10:07:10 2019 +0200. The change “mt76: mt76x0u: do not reset radio on resume” introduces changes as follows. mt76: mt76x0u:donot...
After the device has been alerted, the data transfer proceeds, using the handshake line to clock new data to the receiving interface (this might not be the best implementation, but it is necessary for compatibility with other packet drivers using the parallel port). Performance would be unbearabl...
Modern hardware, of course, has been designed to allow the sharing of interrupts; the PCI bus requires it. Therefore, the Linux kernel supports interrupt sharing on all buses, even those (such as the ISA bus) where sharing has traditionally not been supported. Device drivers for the 2.6 kern...
这样我们就算是配置好了 HC,到这里就算万事俱备,只欠东风了.662 行就设置 uhci->is_initialized 为 1,这意图再明显不过了. 回到 uhci_start 中 , 还剩下最后一个函数 , start_rh() , rh 表示 Root Hub . 这个函数来自 drivers/usb/host/uhci-hcd.c: 324 static void start_rh(struct uhci_hcd *...
Other code has addition modification that it wants to make to the flat device tree before handing it off to the kernel. This causes ft_system_setup() to be called before booting the kernel. CONFIG_OF_IDE_FIXUP U-Boot can detect if an IDE device is present or not. ...
