Abstract:
Embodiments disclose techniques for sharing a context for a coherent accelerator in a kernel of a computer system. A request is received from a first application to perform an I/O operation within a kernel context. The request specifies a first effective address distinct to the first application. The first effective address specifies a location in a first effective address space and a first effective segment identifier. The first effective address is remapped to a second effective address. The second effective address specifies a location in a second effective address space of the kernel context and a second effective segment identifier. A virtual address mapping to a virtual address space within the kernel context is determined. The virtual address is translated to a physical memory address.

Claim (Index 8):
A computer-readable storage medium containing computer program code that, when executed by operation of one or more computer processors, performs an operation comprising:\n receiving a request from a first application to perform an I/O operation within a kernel context, wherein the request specifies a first effective address of a local effective address space distinct to the first application and wherein the first effective address specifies a location in the local effective address space of the kernel context and a first effective segment identifier; remapping the first effective address to a second effective address in a global effective address space shared by the first application and at least a second application, wherein the second effective address specifies a location in the global effective address space of the kernel context and a second effective segment identifier; determining, by a lookup using the second effective segment identifier on a page table and a shared segment table, a virtual address; and translating the virtual address to a physical memory address.
