Dynamic allocation of DMA buffers in input/output adaptors |
摘要 |
A method and apparatus for dynamic allocation of DMA buffers in the DRAM banks of an I/O adaptor. The method and apparatus determine the functional status of the adaptor, allocate critical, volatile DMA buffers in non-critical DRAM banks if the adaptor is fully functional, and allocate critical, volatile DMA buffers in critical DRAM banks if the adaptor is partially functional.
