Publication number: 20240095072Abstract: A method includes, in response to receiving an incoming service request and establishing a call chain of pods of a service mesh network, setting a retry locker parameter to a locked state for each pod in the call chain. A locked retry locker parameter prevents the pod from initiating retries of a service request. The method includes, in response to determining that a pod in the call chain is unavailable, setting the retry locker parameter to an unlocked state for a previous pod just prior to the pod that is unavailable. The unlocked state allows a retry to the pod that is unavailable. In response to the previous pod reaching a retry limit, the method includes setting the retry locker parameter to unlocked for each pod in the call chain and sending a service termination message to a service requester.Type: ApplicationFiled: September 21, 2022Publication date: March 21, 2024Inventors: Yue Wang, Wei Wu, Xin Peng Liu, Liang Wang, Biao Chai

Publication number: 20240012463Abstract: Example techniques related to portable playback device power management. An example implementation involves launching a power coordinator background process, the power coordinator background process having multiple client programs and establishing respective inter-process communication (IPC) mechanisms between the multiple client programs and the power coordinator background process. The implementation further involves receiving, via the established IPC mechanisms from the multiple client programs, messages indicating that the respective client program is ready to suspend, and determining that each client program of the multiple client programs is ready to suspend. The implementation further includes sending instructions to the operating system to kernel suspend. While in kernel suspend, the playback device detects a particular trigger to kernel resume and in response, performs a kernel resume.Type: ApplicationFiled: September 25, 2023Publication date: January 11, 2024Inventors: Joshua Nicholas, Brenda Stefani, Liang Chai, Xiang Wang, Allan Velzy, Edwin Joseph Fitzpatrick, III, Hrishikesh Gossain

Publication number: 20230085004Abstract: Example techniques related to portable playback device power management. An example implementation includes a main SoC comprising main processor(s), an auxiliary processor, and a kernel that executes on the one or more main processor cores. During kernel suspend of the kernel, a power management microcontroller monitors a battery for conditions corresponding to respective wake-on-battery triggers, detects that the monitored conditions correspond to a particular wake-on-battery trigger; and in response, sends, to the auxiliary processor, an interrupt corresponding to a particular wake-on-battery trigger, wherein the interrupt causes the auxiliary processor core to enable the main processor(s) and resume the kernel from kernel suspend. After resuming from kernel suspend, the kernel adds a first kernel resume source event indicating the particular wake-on-battery trigger to a power event queue.Type: ApplicationFiled: November 22, 2022Publication date: March 16, 2023Inventors: Liang Chai, Xiang Wang, Brenda Stefani, Lyford Beverage, JR., Allan Velzy, Edwin Joseph Fitzpatrick, III
