Michael Brown	bd95927386	Accelerate memcpy() by around 32% on large, dword-aligned copies.	2007-01-18 15:18:02 +00:00
Michael Brown	d48d0fb1bb	Add the concept of a "user pointer" (similar to the void __user * in ... the kernel), which encapsulates the information needed to refer to an external buffer. Under normal operation, this can just be a void * equivalent, but under -DKEEP_IT_REAL it would be a segoff_t equivalent. Use this concept to avoid the need for bounce buffers in int13.c, which reduces memory usage and opens up the possibility of using multi-sector reads. Extend the block-device API and the SCSI block device implementation to support multi-sector reads. Update iscsi.c to use user buffers. Move the obsolete portions of realmode.h to old_realmode.h. MS-DOS now boots an order of magnitude faster over iSCSI (~10 seconds from power-up to C:> prompt in bochs).	2006-05-19 15:06:51 +00:00
