Norman Feske	0dbb5e1696	Propagate 'Range_allocator::alloc_aligned' errors ... This patch reflects eventual allocation errors in a more specific way to the caller of 'alloc_aligned', in particular out-of-metadata and out-of-memory are considered as different conditions. Related to issue #526.	2012-11-28 22:51:09 +01:00
Sebastian Sumpf	71b2b42936	USB: Dimension back-end allocators dynamically ... Use avaible ram session quota to determine the size of the memory allocators. Fixes #331	2012-08-30 11:12:32 +02:00
Sebastian Sumpf	3207b4eed0	USB: Performance improvements ... Added SKB bitmap allocator, use Nic::Packet_allocator in packet stream, use slab allocators on top of back-end AVL allocator, split allocators in cached/uncached for general purpose/DMA allocation, added patch to original code to distinguish cached or uncached memory requests, take advantage of and implement TX bursts (or SKB batching), call interrupt handlers until they return unhandled.	2012-08-07 22:22:45 +02:00
