A method for implementing LINUX kernel hot patch, an electronic device and a computer readable medium, the method includes: modifying header instruction code of a patched function in an atomic operation mode, and jumping directly or indirectly from a patched function address to a patching function address to activate a patching function. The method for implementing LINUX kernel hot patch can achieve the activation of the patching function without restarting the LINUX system.

Methods that boot a secondary operating system (O/S) kernel with reclaimed primary kernel memory are disclosed herein. One method includes booting, via a processor performing a boot algorithm, a secondary kernel for an O/S in response to a primary kernel for the O/S going offline, in which the secondary kernel is configured to be loaded to a reserved memory area. The method further includes reclaiming memory space from the primary kernel for use in booting the secondary kernel in response to a determination that the reserved memory area includes insufficient memory space for completing the boot algorithm. Also disclosed herein are apparatus, systems, and computer program products that can include, perform, and/or implement the methods for providing a secondary kernel that includes a reserved area in memory.

A device includes a power button and a fingerprint sensor, where the power button is integrated with the fingerprint sensor. A method is applied to a process in which a user presses the power button to start up the device. The method includes obtaining fingerprint information acquired by the fingerprint sensor, and saving the fingerprint information. The method further includes obtaining a fingerprint authentication request. The method further includes providing the fingerprint information to perform fingerprint authentication to log in to an operating system of the device.

A power supply control unit controls supply and stoppage of power to a plurality of blocks having two or more modules. A clock control unit controls supply and stoppage of clocks to the two or more modules in the plurality of blocks. A first control unit verifies validity of a program stored in a storage unit. A second control unit executes the program determined to be valid as a result of verification by the first control unit. While the program is verified by the first control unit, the power supply control unit supplies power to a block including a module required for the verification, and the clock control unit stops a clock to a module not required for the verification of the block including a module required for the verification.

A boot method for an embedded system is provided. The embedded system includes two mainboards each provided with a baseboard management controller (BMC), a non-volatile memory unit and a network adapter. When the embedded system is turned on, each of the BMCs performs a boot procedure, and then loads an operating system (OS) image file from a corresponding non-volatile memory unit to execute an operating system. When one BMC fails to load the OS image file or to execute the operating system, the BMC causes the corresponding network adapter to communicate with the other network adapter to acquire the OS image file from, the non-volatile memory unit on the other mainboard, so as to replace the OS image file in the corresponding non-volatile memory unit, and directly loads the OS image thus acquired to execute the operating system.

A method for configuring a computer system memory, includes powering on the computer system; retrieving options for initializing the computer system; assigning to a first segment of the memory a first pre-defined setting; assigning to a second segment of the memory a second pre-defined setting; and booting the computer system.

In an embodiment, a system includes a contactless reader and an apparatus. The apparatus includes a contactless transponder including a contactless interface and a transponder wired interface and being configured to communicate with a contactless reader according to a contactless protocol through the contactless interface. The apparatus includes a bus coupled to the transponder wired interface, and at least one module coupled to the bus, the at least one module including a processing circuit, the contactless reader being configured to communicate instructions of a software program executable by the processing circuit to the at least one module through the contactless transponder.

Provided is an in-vehicle information processing apparatus capable of continuously executing an application program run on an OS even while that OS is restarting, a control method, and a computer program. An in-vehicle information processing apparatus according to the present embodiment is installed in a vehicle and includes a control unit that controls a plurality of operating systems (OSs) running on common hardware, wherein the control unit determines whether or not the plurality of OSs need to be restarted, in a case in which the control unit determines that one OS needs to be restarted, runs an application program running on the one OS on another OS different from the one OS, restarts the one OS, and after restart is complete, runs the application program running on the other OS on the one OS.

An information processing apparatus includes a storage unit configured to store at least a first boot program and a second boot program corresponding to the first boot program, a controller configured to read and execute a program, detect, in accordance with occurrence of a read error at reading of the first boot program, an address of a storage area storing a program in which the read error has occurred in the first boot program, and specify, from an address of a storage area storing the second boot program, an address corresponding to the detected address. The controller reads and executes the second boot program stored in the specified address.

An information handling system may perform a quick boot based on a determination that a boot does not require an update to at least one of a firmware and hardware of an information handling system. The information handling system may reboot and may determine whether a boot of the system requires an update to at least one of a firmware and hardware of the information handling system. If the boot does not require an update to the at least one of a firmware and hardware of the information handling system, the information handling system may boot by bypassing one or more basic input/output system (BIOS) power-on self-test (POST) operations.
