Abstract: This application provides a garbage data scrubbing method and a device, and relates to the field of terminals, to resolve a problem that delivering a discard message in a file system transaction affects a user foreground operation. The method includes: obtaining an IO busy/idle status of a terminal at a current moment, where the IO busy/idle status includes a busy state and an idle state (S301); and if the IO busy/idle status of the terminal at the current moment is the idle state, delivering a discard message to a storage device (S302), where the discard message includes an initial address and a size of to-be-scrubbed physical space in the storage device, and the discard message is used to unbind a mapping relationship between a physical address of the to-be-scrubbed physical space and a corresponding logical address.

Abstract: An information processing method and apparatus are disclosed in a multicarrier communications system. In the multicarrier communications system, a terminal is configured with a PCC and at least one SCC. A first base station in which the PCC is located transmits downlink data to the terminal by using a PDSCH on the PCC; and the first base station demodulates a PUCCH on the PCC by using a first format and a second format, to obtain feedback information sent by the terminal, where the first format is a PUCCH format used for a single serving cell, and the second format is a PUCCH format used for a plurality of serving cells. Therefore, a problem that downlink retransmission is continually performed because feedback information cannot be demodulated due to inconsistent PUCCH formats is resolved.

Abstract: A direct memory access (DMA) transmission control method and apparatus, where the method includes selecting a target channel for the target DMA task according to a priority corresponding to the target DMA task when a DMA transmission request for transmitting data of a target DMA task is received, querying a task type and a priority of another DMA task that has occupied a channel and a task type of the target DMA task when the other DMA task exists on the DMA channel, comparing the task type and the priority of the other DMA task that has occupied the channel with the task type and the priority of the target DMA task, and controlling data transmission on the DMA channel according to a comparison result. Hence, the urgent DMA task can be preferentially processed.

Abstract: A method for configuring a fibre channel (FC) storage area network (SAN), and an apparatus, where a first server sends a login request message to a switch, where the login request message includes a first identifier of a first virtual machine (VM) and a world wide group name (WWGN) of a port group of the first VM, enables the switch to establish a correspondence between the first identifier and the WWGN, and enables a storage device to establish the correspondence between the first identifier and the WWGN. A configuration of a first zone and a correspondence of a logical unit number (LUN) are both based on the WWGN. Therefore, in a migration process of the first VM, a network administrator does not need to re-configure a zone, and the storage device does not need to re-configure a correspondence between the first VM and an accessible LUN either.

Abstract: A garbage data scrubbing method includes obtaining an input/output (IO) busy/idle status of a terminal at a current moment, where the IO busy/idle status includes a busy state and an idle state. When the IO busy/idle status of the terminal at the current moment is the idle state, a discard message is delivered to a storage device, where the discard message includes an initial address and a size of to-be-scrubbed physical space in the storage device, and where the discard message is used to unbind a mapping relationship between a physical address of the to-be-scrubbed physical space and a corresponding logical address.

Abstract: A display control method includes: obtaining, by a terminal, orientations and display statuses of a first screen and a second screen; determining, by the terminal, whether a trigger event used for adjusting the display statuses of the first screen and the second screen occurs; and when the trigger event occurs, displaying, by the terminal, adjusted display content on the first screen and the second screen based on the orientations and the display statuses of the first screen and the second screen. By obtaining an orientation and a display status of a terminal screen, when the trigger event occurs, the terminal can adjust the display status of the screen in a timely manner, so that a user can perform an interaction operation and interaction display between different screens.
