Abstract
Techniques are disclosed relating to updating page pools in the context of cached page pool descriptors. In some embodiments, a processor is configured to assign a set of processing work to a first page pool of memory pages. Page manager circuitry may cache page pool descriptor entries in cache circuitry, where a given page pool descriptor entry indicates a set of pages assigned to a page pool. In response to a determination to grow the first page pool, the processor may communicate a grow list to the page manager circuitry, that identifies a set of memory blocks from the memory to be added to the first page pool. The page manager circuitry may then update a cached page pool descriptor entry for the first page pool to indicate the added memory blocks and generate a signal to inform the processor that the cached page pool descriptor entry is updated.
