* 几个结构体 * 通过vmx_init以及create_vm，create_vcpu部分TODO * kvm_run完成一半 * 能够成功vmlaunch，但是在vmexit时候还有些问题未排查出来 * 解决了vmlaunch导致的cpu_reset的问题 * 整理代码 * 暂时性push到hyc仓库 * 修改内存虚拟化部分参数传入，解决死锁问题 * 初步完成ept映射.但不停EPT_VIOLATION * 初步完成了EPT映射,但是读写内存还是有点问题 * fixme * 更新了一些truncate到from_bits_unchecked的实现 * 完成内存虚拟化EPT_VIOLATION的映射 * fmt * Remove /fixme from .gitignore * Remove /fixme file * Update kernel/src/init/init.rs Co-authored-by: Samuel Dai <[email protected]> * Update kernel/src/init/init.rs Co-authored-by: Samuel Dai <[email protected]> * 修改了注释格式，删除了附带的一些文件操作 * feat(syscall): 实现syscall restart (#1075) 能够在系统调用返回ERESTARTSYS时,信号处理结束后,自动重启系统调用. TODO: 实现wait等需要restart_block的系统调用的重启 Signed-off-by: longjin <[email protected]> * chore: update docker image version in script && update doc (#1076) * chore: update docker image version in script * chore: replace lots of spaces with newline in doc * fix: 修复wait4系统调用部分语义与Linux不一致的问题 (#1080) * fix: 修复wait4系统调用部分语义与Linux不一致的问题 解决wait不住/wait之后卡死的bug --------- Signed-off-by: longjin <[email protected]> * feat(fs/syscall): 实现fchdir系统调用 (#1081) Signed-off-by: longjin <[email protected]> * fix(mm): 修复fat文件系统的PageCache同步问题 (#1005) --------- Co-authored-by: longjin <[email protected]> * fix: 修正nographic启动时,控制台日志未能输出到文件的问题 (#1082) Signed-off-by: longjin <[email protected]> * fix(process): 修复copy_process的一些bug & 支持默认init进程传参 (#1083) - 修复`copy_process`函数对标志位处理不正确的bug - init进程搜索列表中,支持为默认init程序传入参数 Signed-off-by: longjin <[email protected]> * feat: 完善sys_reboot (#1084) * fix(process): 修复copy_process的一些bug & 支持默认init进程传参 - 修复`copy_process`函数对标志位处理不正确的bug - init进程搜索列表中,支持为默认init程序传入参数 Signed-off-by: longjin <[email protected]> * feat: 完善sys_reboot - 校验magic number - 支持多个cmd (具体内容未实现) Signed-off-by: longjin <[email protected]> --------- Signed-off-by: longjin <[email protected]> * fix: 修复do_wait函数在wait所有子进程时,忘了释放锁就sleep的bug (#1089) Signed-off-by: longjin <[email protected]> * pull主线并且fmt --------- Signed-off-by: longjin <[email protected]> Co-authored-by: GnoCiYeH <[email protected]> Co-authored-by: Samuel Dai <[email protected]> Co-authored-by: LoGin <[email protected]> Co-authored-by: LIU Yuwei <[email protected]> Co-authored-by: MemoryShore <[email protected]>
