匹配component的规则例化流程 2.3 master聚合component component_master_add_with_match()按照匹配规则来查找component。遍历component_match链表,若master连接的component组件都有效可用,那么调用component_master_ops.bind来实现各个组件的聚合。此处,component_bind_all()回调各component的bind函数。 master聚合所有component流程...
master即超级设备,执行probe函数时使用component_master_add_with_match函数注册自己到component框架中。 component即普通设备,执行probe函数时使用component_add函数注册自己到component框架中。 两种流程先后顺序并无要求,可随意顺序。每一个设备加入到框架中,框架就尝试进行匹配,当master匹配上所有component后,会调用master的...
如果匹配成功,调用component_attach_master将component添加到master中, 并返回0。 三、component注册 intcomponent_add(structdevice *dev,conststructcomponent_ops *ops){structcomponent *component;intret; component = kzalloc(sizeof(*component), GFP_KERNEL);if(!component)return-ENOMEM; component->ops = ops;...
The formula therefore falls back to the expected calculation with KASAN: the bytecodes take the base address of the KASAN shadow, add to it the offset of the address within the kernel address space divided by 8, and this results in the correct shadow address for the given kernel address. ...
The component might support additional, low-power states F1, F2, and so on. The power policy owner for a device is typically the device's function driver. To enable component-level power management, this driver registers the device with the power management framework (PoFx). By registering ...
Step 3. Add build support of new component in packages/apps/Makefile. Step 4. Run flex-builder -c <component-name> -a <arch>' to build the new component. Step 5. Run flex-builder -i merge-component -a <arch> to merge the new component package into target distro userland. ...

To configure the kernel to panic when an OOM-Kill event occurs, add the following to yoursysctl.conffile: Raw # vim /etc/sysctl.conf … vm.panic_on_oom = 1 For more information on configuring the system to panic at OOM-Kill, and other relevant tunables, refer toWhat are the sysctl ...
Optional: To make this persistent across future kernel upgrades and initramfs rebuilds, add the driver to omit to dracut's permanent configuration: Raw # MODNAME="module_name"; echo "omit_dracutmodules+=\" $MODNAME \"" >> /etc/dracut.conf.d/omit-$MODNAME.conf ...
