插桩之路——为QEMU TCG添加helper以target/i386/translate.c中的gen_helper_syscall为例讲解了添加helper函数的步骤和方法;然后是TCG的定义机制,即gen_helper_xxx和helper_xxx函数的定义机制。 QEMU: Call a Custom Function from TCG以target/arm/translate.c中的gen_helper_exception为例讲解了helper函数的调用模式,...
To add such a device, you can use qm: # qm set <vmid> -ivshmem size=32,name=foo Where the size is in MiB. The file will be located under /dev/shm/pve-shm-$name (the default name is the vmid). Currently the device will get deleted as soon as any VM using it got shutdown ...
fcitx5-configtool 得到类似于下面的图形化操作,步骤大致是 run fcitx --> add input method --> Rime --> apply 重启一下系统,打开kate, 使用win+空格键唤出rime输入法,按F4进行选择五笔或拼音的选择,然后就可以愉快地输入中文了 4.9 上网冲浪 前面已经安装了firefox,现在生成桌面图标 cp /usr/local/share/a...

卡了将近一周,最后发现是qemu的uboot启动方式的问题,在flash中通过uboot.bin镜像进行启动会导致卡在kernel_init()->kernel_init_freeable()->do_one_initcall()->of_platform_default_populate_init()->of_platform_populate()->of_platform_bus_create()->amba_device_add()->amba_device_try_add()函数中...
将可移动设备连入系统时,系统的后台中会依次发生如下事件 外设插入; 总线发现新设备,通知hotplug产生热插拔事件,调用device_add,添加新设备到设备管理系统;ndevice_add中调用kobject_uevent(, KOBJ_ADD),向用户空间广播新设备加入事件通知;这里发出通知的方式,就是netlink; 用户空间运行的daemon(udev)收到event事件广...
gdb.py line to your configuration file "/home/qemu2/.gdbinit"...上面的意思是,为了能够使能vmlinux-gdb.py的执行,需要添加 add-auto-load-safe-path /home/qemu2/qemu/linux-4.4.203/scripts/gdb...参考: Tips for Linux Kernel Development How to Build A Custom Linux Kernel For Qemu Linux Kernel...
