Abstract: With advanced compute capabilities and growing convergence of various wireless standards, it is desired to run multiple wireless standards on a single hardware together. Embodiments are disclosed for lower MAC protocol processing across multiple wireless standards and multiple radios. A common hardware may be used for processing lower MAC flows across multiple wireless standards, e.g., Wi-Fi, LTE, or 5G NR, multiple radios within a wireless standard, multiple users within a wireless standard, and/or different directions of radio. The implementation may support partial data processing of a flow, switching across flows, and context saving/restoring of flows. Furthermore, for better performance, looking ahead of flows and prefetching of context and data may also be implemented. Embodiments of the present patent disclosure may result in a very area-efficient and power-efficient hardware implementation for lower MAC protocol processing.

Abstract: Enhanced Common Packet Radio Interface (eCPRI) based Fronthaul forms the foundation for open radio access network (O-RAN). O-RAN envisages splitting the radio into two parts, a Distributed Unit (DU) and Radio Units (RU), interconnected using high speed Fronthaul links. O-RAN and eCPRI for 5G/NR place demands for high speed Fronthaul with low latency, and high network bandwidth requirements. In the present disclosure, embodiments for configurable eCPRI Fronthaul solutions are disclosed. Various hardware accelerator implementations are presented for control plane and user plane traffic. The hardware accelerator implementation may support DU and RRU functionality required by eCPRI with minimal software intervention. The configurable eCPRI Fronthaul may support different data flows and meet different performance demands of DU and RRU.

Abstract: A filesystem can be shared between containers. For example, a computing device having a host filesystem can launch a first container from an image file. Launching the first container can include creating an initialization directory for the first container on the host filesystem. The initialization directory can include a filesystem to be shared between containers. Launching the first container can also include creating a first filesystem directory for the first container on the host filesystem and mounting the initialization directory to the first filesystem directory. The computing device can also launch a second container from the image file. Launching the second container can include creating a second filesystem directory for the second container on the host filesystem and mounting the initialization directory to the second filesystem directory to enable the second container to access the filesystem.

Abstract: Direct access to host memory for guests is disclosed. For example, a system includes a processor, a host memory, a filesystem daemon, a guest including a storage controller, and a filesystem queue accessible to the filesystem daemon and the storage controller. The storage controller receives a file retrieval request associated with a file stored in the host memory and forwards the file retrieval request to the filesystem daemon by adding the file retrieval request to the filesystem queue. The filesystem daemon retrieves the file retrieval request from the filesystem queue, determines a host memory address (HMA) associated with the file, and causes the HMA to be mapped to a guest memory address (GMA). The guest accesses the file in the host memory with the GMA, and later terminates access to the file, where the filesystem daemon is then configured cause the GMA to be unmapped.

Abstract: Shared filesystem metadata caching is disclosed. For example, a system includes a guest with a storage controller (SC) and a metadata cache on a host with a filesystem daemon (FSD), and a host memory storing a registration table (RT). The SC receives a first metadata request associated with a file stored in the host memory. A first version identifier (VID) of metadata associated with the file is retrieved from the metadata cache and validated against a corresponding second VID in the RT. Upon determining the first VID matches the second VID, the SC responds to the first metadata request based on the metadata. Upon determining the first VID fails to match the second VID, the SC requests the FSD to update the metadata. The first VID is updated to match the second VID and the SC responds to the first metadata request based on the updated metadata.

Abstract: Implementations of the disclosure provide for size adjustable volumes for containers. A method of the disclosure includes determining, by a processing device of a Platform-as-a-Service (PaaS) system, a size limitation of a container, where the size limitation is associated with disk space usage of a storage volume group. The amount of disk space used by applications of the container is monitored in view of the size limitation of the container. Responsive to determining that the amount of the disk space used by the applications of the container satisfies a threshold, a storage volume of the storage volume group is allocated to the container in view of the size limitation of the container.

Abstract: An access control engine can enable a host operating system to propagate a private resource of an isolated virtual environment, such as a container, running on the host operating system outside of the isolated virtual environment. The private resource can include, for example, a file system mounted within the isolated virtual environment. The access control engine can receive a command and launch the isolated virtual environment in response to the command. Also, in response to the command, the access control engine can interface with a kernel of the host operating system to configure the isolated virtual environment so that the private resource is accessible outside the isolated virtual environment.

Abstract: Mirrored byte addressable storage is disclosed. For example, first and second persistent memories store first and second pluralities of pages, both associated with a plurality of page states in a mirror state log in a third persistent memory. A mirror engine executing on a processor with a processor cache detects a write fault associated with the first page of the first plurality of pages and in response, updates a first page state to a dirty-nosync state. A notice of a flush operation of the processor cache associated with first data is received. The first data becomes persistent in the first page of the first plurality of pages after the flush operation; then the first page state is updated to a clean-nosync state. The first data is then copied to the first page of the second plurality of pages; then the first page state is updated to a clean-sync state.

For example, a system includes (i) a processor, (ii) a host memory, (iii) a hypervisor including a filesystem daemon, (iv) a guest including a storage controller, and (v) a first filesystem queue. The storage controller is configured to receive a file request, translate the file request, and add the translated file request to a filesystem queue. The filesystem daemon is configured to retrieve the translated file request from the filesystem queue and provide access to a file in the host memory identified in the file request to the guest.
