Minimizing the total number of commands sent (typical command latency - * including drive and bus mastering host overhead is as high as 4.5ms) - * to transfer a given amount of data. - * - * This is accomplished by placing no arbitrary limit on the number - * of scatter/gather buffers supported, since we can transfer 1K - * per scatter/gather buffer without Eric's cluster patches, - * 4K with. - * - * 2. Minimizing the number of fatal interrupts serviced, since - * fatal interrupts halt the SCSI I/O processor. Basically, - * this means offloading the practical maximum amount of processing - * to the SCSI chip. - * - * On the NCR53c810/820/720, this is accomplished by using - * interrupt-on-the-fly signals when commands complete, - * and only handling fatal errors and SDTR / WDTR messages - * in the host code. - * - * On the NCR53c710, interrupts are generated as on the NCR53c8x0, - * only the lack of a interrupt-on-the-fly facility complicates - * things. Also, SCSI ID registers and commands are - * bit fielded rather than binary encoded. - * - * On the NCR53c700 and NCR53c700-66, operations that are done via - * indirect, table mode on the more advanced chips must be - * replaced by calls through a jump table which - * acts as a surrogate for the DSA. Unfortunately, this - * will mean that we must service an interrupt for each - * disconnect/reconnect. - * - * 3. Eliminating latency by pipelining operations at the different levels. - * - * This driver allows a configurable number of commands to be enqueued - * for each target/lun combination (experimentally, I have discovered - * that two seems to work best) and will ultimately allow for - * SCSI-II tagged queuing. - * - * - * Architecture : - * This driver is built around a Linux queue of commands waiting to - * be executed, and a shared Linux/NCR array of commands to start. Commands - * are transferred to the array by the run_process_issue_queue() function - * which is called whenever a command completes. - * - * As commands are completed, the interrupt routine is triggered, - * looks for commands in the linked list of completed commands with - * valid status, removes these commands from a list of running commands, - * calls the done routine, and flags their target/luns as not busy. - * - * Due to limitations in the intelligence of the NCR chips, certain - * concessions are made.

Parity checking is currently disabled, and a few things should - * happen here now that we support synchronous SCSI transfers : - * 1. On soft-reset, we shoould set the EPC (Enable Parity Checking) - * and AAP (Assert SATN/ on parity error) bits in SCNTL0. - * - * 2. We should enable the parity interrupt in the SIEN0 register. - * - * 3. intr_phase_mismatch() needs to believe that message out is - * always an "acceptable" phase to have a mismatch in. If - * the old phase was MSG_IN, we should send a MESSAGE PARITY - * error. If the old phase was something else, we should send - * a INITIATOR_DETECTED_ERROR message. Note that this could - * cause a RESTORE POINTERS message; so we should handle that - * correctly first. Instead, we should probably do an - * initiator_abort. - * - * 4. MPEE bit of CTEST4 should be set so we get interrupted if - * we detect an error. - * - * - * 5. The initial code has been tested on the NCR53c810.
