Abstract: Embodiments described herein provide techniques to manage drivers in a user space in a data processing system. One embodiment provides a data processing system configured perform operations, comprising discovering a hardware device communicatively coupled to the communication bus, launching a user space driver daemon, establishing an inter-process communication (IPC) link between a first proxy interface for the user space driver daemon and a second proxy interface for a server process in a kernel space, receiving, at the first proxy interface, an access right to enable access to a memory buffer in the kernel space, and relaying an access request for the memory buffer from the user space driver daemon via a third-party proxy interface to enable the user space driver daemon to access the memory buffer, the access request based on the access right.

Abstract: A device may include a secure processor and a secure memory coupled to the secure processor. The secure memory may be inaccessible to other device systems. The secure processor may store some keys and/or entropy values in the secure memory and other keys and/or entropy values outside the secure memory. The keys and/or entropy values stored outside the secure memory may be encrypted using information stored inside the secure memory.

Abstract: The present disclosure generally relates to multifunction physical buttons. An electronic device detects activation of a physical button. The device determines whether a set of one or more criteria are met. If the set of one or more criteria are met, the device captures an image using an image sensor. If the set of one or more criteria are not met, the device turns off the display of the device. Thus, the same physical button can perform different functions based on whether the set of one or more criteria are met.
Abstract translation: 本公开通常涉及多功能物理按钮。 电子设备检测物理按钮的激活。 设备确定是否满足一个或多个标准的集合。 如果满足一个或多个条件的集合,则该设备使用图像传感器捕获图像。 如果不符合一个或多个条件的集合,则设备将关闭设备的显示。 因此,相同的物理按钮可以基于满足一个或多个标准的集合来执行不同的功能。
