Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for storing an address in a memory of a switch. One of the systems includes a switch that receives packets from and delivers packets to devices connected to a bus without any components on the bus between the switch and each of the devices, a memory integrated into the switch to store a mapping of virtual addresses to physical addresses, and a storage medium integrated into the switch storing instructions executable by the switch to cause the switch to perform operations including receiving a response to an address translation request for a device connected to the switch by the bus, the response including a mapping of a virtual address to a physical address, and storing, in the memory, the mapping of the virtual address to the physical address in response to receiving the response.

Abstract: A method includes for each processed interrupt: determining whether the interrupt is a user mode interrupt; upon determining that the interrupt is a user mode interrupt, determining a stack location to insert an entry corresponding to the user mode interrupt, the stack location being calculated by adjusting a current stack pointer by a red zone offset; and inserting the entry corresponding to the user mode interrupt into the stack at the stack location.
Abstract translation: 一种方法包括对每个处理的中断：确定中断是否是用户模式中断; 在确定中断是用户模式中断时，确定堆栈位置以插入对应于用户模式中断的条目，通过将当前堆栈指针调整为红色区域偏移来计算堆栈位置; 并将与用户模式中断相对应的条目插入堆栈位置的堆栈。

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for memory requests by a virtual machine. One of the methods includes initiating a migration process to move an application executing on a first device from the first device to a second device by copying pages of data, stored in a memory of the first device and used for the execution of the application, from the first device to the second device while continuing to execute the application on the first device, updating, by the first device, one or more bytes in at least one of the pages of data in response to executing the application on the first device during the migration process, stopping execution of the application on the first device, and copying the updated bytes from the first device to the second device to cause the second device to continue execution of the application.
