2003-12-16	Pass gcc -Wsign-compare; ok grange@	Todd C. Miller

2003-11-19	Sync with NetBSD probe code: deal with non-pullups ide bus when	Alexander Yurchenko
	testing status register and a better comments on probe logic. Tested on i386, sparc64 and macppc by me, jmc@, matthieu@, sturm@ and drahn@. ok costa@
2003-11-17	Various cleanups, knf, better debug messages.	Alexander Yurchenko

2003-11-17	Don't wait for DRQ after issuing IDENTIFY command; instead check for DRQ	Alexander Yurchenko
	asserted after BSY is cleared in data read codepath. Solves delays in probe. The first version of this diff was done by costa@ a long time ago but had some issues. This one is a partial sync with NetBSD. ok costa@
2003-11-13	One byte can't hold a value > 255.	Alexander Yurchenko
	Spotted by Mr. GCC3.
2003-11-05	Back wdc reset change, now in more careful variant.	Alexander Yurchenko
	Tested on matthieu's U5.
2003-10-31	Back all the changes except the wdc reset part, this will come later.	Alexander Yurchenko
	Tested on matthieu's U5.
2003-10-29	Revert to 1.70 for now which is the last working version on my u5.	Matthieu Herrb
	ok deraadt@
2003-10-27	Skip ATA modes detection for SATA drives, it's useless and some	Alexander Yurchenko
	SATA drives really don't like it. Add a delay between drive reset and issuing IDENTIFY command, some drives need it (from NetBSD). This fixes problems with SATA drives reported by Jonathon Fletcher <jonathon.fletcher@pobox.com>. He also provided access to the test machine.
2003-10-26	Print error registers values in debug message after reset too.	Alexander Yurchenko

2003-10-26	Device reset improvements:	Alexander Yurchenko
	- put the reset protocol itself in the separate function __wdcdo_reset() so we don't need anymore to keep in sync two reset code paths; - change the reset protocol to something like FreeBSD and NetBSD do, this fixes slave ATA drive detect with weird ATAPI master (reported by fgsch@); Discussed with costa@. Tested by me, fgsch@, millert@, canacar@.
2003-10-21	typos from Tom Cosgrove;	Jason McIntyre
	Tom: I did not commit a couple of your changes. i did not include some punctuation fixes (full stops, etc.) mnemorable -> mnemonic: i decided memorable was probably better instrunctions -> instruction: i kept the plural
2003-10-20	typo; netbsd	Alexander Yurchenko

2003-10-19	KNF	Alexander Yurchenko

2003-10-17	Merge an old fix from NetBSD:	Alexander Yurchenko
	- do not stop/unload current DMA operation if an IRQ was not detected by DMA engine unless the force flag was given, fixes DMA problems in shared IRQ setups; - ack interrupt before entering DMA codepath Tested by many. Work by niklas@ but he doesn't want to commit it for some reason.
2003-10-16	Cleanup a bit, more pretty debug messages.	Alexander Yurchenko

2003-10-16	Allow setting of wdcdebug*_mask variables via preprocessor defines.	Alexander Yurchenko
	This makes creating debug kernels be much more easy.
2003-10-16	Kill two static function declarations.	Alexander Yurchenko

2003-09-28	kill trailing spaces, no functional changes	Alexander Yurchenko

2003-07-06	trailing spaces	Alexander Yurchenko

2003-06-25	Restore the original wdcdebug_mask instead of clearing DEBUG_PROBE when	Henric Jungheim
	done with it. This makes "wdcprobe()" consistent with "wdcattach()". ok grange@
2003-02-21	Fix Manuel Bouyer's copyright, from NetBSD	Alexander Yurchenko
	ok deraadt@
2003-02-13	Don't force all ATAPI devices to PIO mode 3, there are	Alexander Yurchenko
	devices which only support PIO mode 2 or less. Use atap_oldpiotiming to obtain supported mode for such devices. Also use SET FEATURES only for PIO mode > 2. Work by Alec Skelly <alec@dtkco.com> with my little help. ok costa@
2002-12-22	Define atagettrace_t type and use it instead of struct atagettrace.	Alexander Yurchenko
	ok costa@
2002-12-22	No more magic wdc events types, give them names.	Alexander Yurchenko
	ok costa@
2002-12-19	Protect WDCDEBUG_PRINT macro with do {} while (0)	Alexander Yurchenko
	ok costa@
2002-12-12	Always use queue(3) macros.	Alexander Yurchenko
	ok chris@ gluk@
2002-10-16	minor formatting.	Artur Grabowski

2002-10-09	Remove trailing '\n's from panic messages.	Kenneth R Westerback
	Started by a commit to siop from provos@netbsd.org. ok miod@ millert@
2002-07-02	Fix PIO write state machine. This has been totally broken since 2.5, but since	Constantine Sapuntzakis
	this code path is only executed for IOCTLs, and all of our IOCTLs only read from the device, nobody noticed. Thanks to grange and gluk for finding this one.
2002-05-24	protect biodone with splbio (this is the first time the splbio is	Artur Grabowski
	not really needed, just added to satisfy the assert).
2002-05-24	Replace a home-grown splassert-like thing with the real stuff.	Artur Grabowski

2002-05-03	LBA48 support.	Grigoriy Orlov
	Adopted from NetBSD by Alexander Yurchenko <grange@openbsd.ru>. costa@ ok.
2002-03-16	The new code logs the control signals on the IDE bus. You can extract the log	Constantine Sapuntzakis
	using atactl <device> dump. The log will help us support more devices. Send logs to csapuntz@
2002-03-14	First round of __P removal in sys	Todd C. Miller

2002-01-23	Pool deals fairly well with physical memory shortage, but it doesn't deal	Artur Grabowski
	well (not at all) with shortages of the vm_map where the pages are mapped (usually kmem_map). Try to deal with it: - group all information the backend allocator for a pool in a separate struct. The pool will only have a pointer to that struct. - change the pool_init API to reflect that. - link all pools allocating from the same allocator on a linked list. - Since an allocator is responsible to wait for physical memory it will only fail (waitok) when it runs out of its backing vm_map, carefully drain pools using the same allocator so that va space is freed. (see comments in code for caveats and details). - change pool_reclaim to return if it actually succeeded to free some memory, use that information to make draining easier and more efficient. - get rid of PR_URGENT, noone uses it.
2002-01-12	Don't try UDMA modes if they aren't supported by the controller	Jason Wright
	even if the flags enable it. chris@ ok
2002-01-07	pass the proc* down the ioctl chain to controller; mjacob@ csapuntz@ ok	Michael Shalayeff

2001-11-06	Replace inclusion of <vm/foo.h> with the correct <uvm/bar.h> when necessary.	Miod Vallat
	(Look ma, I might have broken the tree)
2001-08-23	initialize the channel timeout earlier.	Artur Grabowski

2001-07-31	Go down only one Ultra DMA mode at a time. Thanks to Matt Evans for	Constantine Sapuntzakis
	suggesting this fix. Update atapiscsi Ultra DMA downgrade logic.
2001-07-27	Yet another probe fix. Switch to the right drive before looking at registers	Constantine Sapuntzakis

2001-07-21	Undo last fix to ata_wdc.c. Don't deregister timeout in generic code	Constantine Sapuntzakis

2001-07-19	Fix slave ATAPI device detect broken by last patch	Constantine Sapuntzakis

2001-07-12	Rework of probe code. Try better to deal with floating buses. Depending	Constantine Sapuntzakis
	on the value floating on the bus, we would occasionally skip the register writability tests. Whoops... Move fix for a flash device that doesn't wake up until a command is sent Try to supress spurious interrupts. However, if one does happen, acknowledge it anyway by reading status. This prevents the interrupt condition from persisting.
2001-06-25	Fix excessive resets and device probes by storing IDENTIFY results in the	Constantine Sapuntzakis
	drvp structure
2001-06-24	remove cold.	Federico G. Schwindt

2001-06-06	Don't forget to make it compile.	Angelos D. Keromytis

2001-06-05	Don't forget to init b_dep.	Artur Grabowski

2001-05-01	Add a 250ms wait in attach if ATAPI drives present on channel. Some	Constantine Sapuntzakis
	ATAPI devices need a while to boot their firmware, esp. if there is a CD in the drive. Sending them commands early causes them to wedge or abort those commands.
