Abstract: Methods and systems for device driver compilation dispensation of consumable compositions are provided. A method for compiling device drivers may include, but is not limited to: (a) installing a host OS on a compiler server; (b) installing a plurality of target OS on the compile server; (c) installing a dynamic kernel module support package (DKMS) on the compile server for at least one of the plurality of target OS; (d) compiling a driver module on the compile server for a first target OS of the plurality of target OS; and (e) compiling a driver module on the compile server for a second target OS of the plurality of OS.

Abstract: The present invention is a method for handling an operation system kernel-provided command via a software-based device driver. The method includes receiving the operation system kernel-provided command from an operation system kernel. The method further includes determining if a kernel virtual address is required for responding to the command. The method further includes initiating a Direct Memory Access (DMA) operation for providing data to the operating system kernel in response to the command when a kernel virtual address is not required for responding to the command. The method further includes allocating a device driver buffer with a DMA address and a virtual address when a kernel virtual address is required for responding to the command.

Abstract: A method of reading desired data from drives in a RAID1 data storage system, by determining a starting address of the desired data, designating the starting address as a begin read address, designating one of the drives in the data storage system as the current drive, and iteratively repeating the following steps until all of the desired data has been copied to a buffer: (1) reading the desired data from the current drive starting at the begin read address and copying the desired data from the current drive into the buffer until an error is encountered, which error indicates corrupted data, (2) determining an error address of the error, (3) designating the error address as the begin read address, and (4) designating another of the drives in the data storage system as the current drive.

Abstract: Methods and systems for device driver compilation dispensation of consumable compositions are provided. A method for administering a consumable composition may comprise: (a) installing a host OS on a compiler server; (b) installing a plurality of target OS on the compile server; (c) installing a dynamic kernel module support package (DKMS) on the compile server for at least one of the plurality of target OS; (d) compiling a driver module on the compile server for a first target OS of the plurality of target OS; and (e) compiling a driver module on the compile server for a second target OS of the plurality of OS.
