* Put in a hack (yep a real hack) for multiple cylinder reads. - * Not convinced its working. - * - * 5/4/96:DAG: Added asm/hardware.h and use IOC_ macros - * Rewrote dma code in mfm.S (again!) - now takes a word at a time - * from main RAM for speed; still doesn't feel speedy! - * - * 20/4/96:DAG: After rewriting mfm.S a heck of a lot of times and speeding - * things up, I've finally figured out why its so damn slow. - * Linux is only reading a block at a time, and so you never - * get more than 1K per disc revoloution ~=60K/second. - * - * 27/4/96:DAG: On Russell's advice I change ll_rw_blk.c to ask it to - * join adjacent blocks together. Everything falls flat on its - * face. - * Four hours of debugging later; I hadn't realised that - * ll_rw_blk would be so generous as to join blocks whose - * results aren't going into consecutive buffers. - * - * OK; severe rehacking of mfm_rw_interrupt; now end_request's - * as soon as its DMA'd each request. Odd thing is that - * we are sometimes getting interrupts where we are not transferring - * any data; why? Is that what happens when you miss? I doubt - * it; are we too fast? No - its just at command ends. Got 240K/s - * better than before, but RiscOS hits 480K/s - * - * 25/6/96:RMK: Fixed init code to allow the MFM podule to work. Increased the - * number of errors for my Miniscribe drive (8425). - * - * 30/6/96:DAG: Russell suggested that a check drive 0 might turn the LEDs off - * - so in request_done just before it clears Busy it sends a - * check drive 0 - and the LEDs go off!!!! - * - * Added test for mainboard controller. - Removes need for separate - * define. - * - * 13/7/96:DAG: Changed hardware sectore size to 512 in attempt to make - * IM drivers work. - * 21/7/96:DAG: Took out old image file stuff (accessing it now produces an IO - * error.) - * - * 17/8/96:DAG: Ran through indent -kr -i8; evil - all my nice 2 character indents - * gone :-( Hand modified afterwards. - * Took out last remains of the older image map system. - * - * 22/9/96:DAG: Changed mfm.S so it will carry on DMA'ing til; BSY is dropped - * Changed mfm_rw_intr so that it doesn't follow the error - * code until BSY is dropped. Nope - still broke. Problem - * may revolve around when it reads the results for the error - * number? - * - *16/11/96:DAG: Modified for 2.0.18; request_irq changed - * - *17/12/96:RMK: Various cleanups, reorganisation, and the changes for new IO system. - * Improved probe for onboard MFM chip - it was hanging on my A5k. - * Added autodetect CHS code such that we don't rely on the presence - * of an ADFS boot block.
