2007-07-11	Use the full 64 bits available when reporting sizes; now bioctl shows	Otto Moerbeek
	the correct size for my 4.TB volume. Original diff from dlg@ with some tweaks by me; ok dlg@
2007-06-24	rework sensor tasks to use the kernels generic workq rather than a special	David Gwynne
	kernel thread of its own. the api has changed (which will be fixed in the manpage shortly) so all the users of sensor tasks that i can find have been fixed too. noone tested, so its going in to force people to run with it. "put it in" deraadt@
2007-05-29	sprinkle some SMALL_KERNEL to permit bio/softraid to run on boot media	Todd T. Fries
	ok marco@ then suggested deraadt@
2007-05-20	Add missing arguments to printf.	Ray Lai
	OK tedu@, dlg@.
2007-03-27	more grammar fixups; from bret lambert and myself	Jason McIntyre

2007-03-27	grammar from bret lambert, and one more from me;	Jason McIntyre

2007-03-22	split userland & kernel struct sensor/sensordev so that the addition	Theo de Raadt
	of new fields in the future is less disruptive. This is done similar to how struct proc is handled for ps(1). ok jmc (man page changes) tested fkr simon, and more suggestions from millert
2007-02-20	No use checking malloc return when called with M_WAITOK.	Thordur I. Bjornsson
	ok dlg@, tested by jolan@
2006-12-23	adapt to new two-level sensor api; Constantine A. Murenin	Theo de Raadt

2006-12-22	always include sensors.h	Theo de Raadt

2006-11-28	give scsi controllers a real attach args to fill in when attaching scsibus.	David Gwynne
	ok miod@ marco@ deraadt@
2006-11-04	query the firmware for the number of volumes, and then iterate through them	David Gwynne
	to get the right names for sensor creation.
2006-11-01	dont walk the device list looking for our scsibus, it is stashed when we	David Gwynne
	attach it.
2006-11-01	whitespace fixes	David Gwynne

2006-10-31	first cut at sensors	Jolan Luff
	help from & ok dlg@
2006-09-25	well, this is embarrassing.	David Gwynne
	it turns out a drivers detach code isnt called when the machine is shutting down, which meant my bits to stop bgrb and sync the cache werent being run. without those bits being run the filesystems on these controllers were never clean on reboot, so we'd always get an fsck. so now we provide a shutdown hook which does get run on shutdown to sync the cache properly. found by claudio@
2006-09-25	enabling interrupts isnt a bug, so dont put XXX next to it.	David Gwynne
	only ack the interrupts we deal with in the interrupt handler. use the correct macros when setting the interrupt mask.
2006-08-28	move the firmware messaging under NBIO since it's only used by bio.	David Gwynne

2006-08-28	turns out the volume info contains a bitmap of failed physdisks in it, so	David Gwynne
	i can just check if this is non zero to see if a volume is degraded. this means i dont have to pull the raid info page to find failed disks in the volume inquiry.
2006-08-27	sigh, this is annoying. it appears that the arc firmware doesnt care if a	David Gwynne
	volume is degraded, just if it is working or not. if a volume is degraded, its still online, so we have to go look for missing disks. if a disk has been replaced, but it is yet to be rebuilt, the firmware kindly tells us that it needs rebuilding. we can figure out if a volume is degraded using these two facts.
2006-08-27	try to get the status of the volume out of the arc firmware and into	David Gwynne
	bioctl output. this is actually a bit of a struggle since the firmware doesnt represent these states well at all. im only showing the obvious ones: online, init, rebuild, and offline. i have no idea how they tell if a volume is degraded.
2006-08-27	if a disk dissapears out of a raidset, then the raid info will list its id	David Gwynne
	as 0xff, and the command to query that phys disk will fail and cause the ioctl to get stuck. so if the disk id is 0xff, fake an offline disk on another bus since bioctl doesnt know how to show that properly.
2006-08-27	little nit	David Gwynne

2006-08-25	fill in the controllers name in the inq ioctl. spotted by deraadt@	David Gwynne

2006-08-24	show the firmware revision of the disks.	David Gwynne

2006-08-24	report the size of the disks and volumes correctly.	David Gwynne

2006-08-24	too much copy and paste. report raid 1 correctly.	David Gwynne

2006-08-24	ignore passthru volumes, struct bioc_vol isnt smart enough to know what	David Gwynne
	they are.
2006-08-24	figure out the raid level of the volume.	David Gwynne

2006-08-24	oops, im unlocking too often	David Gwynne

2006-08-24	a start at the BIOC INQ, VOL, and DISK ioctls for fetching information	David Gwynne
	about the disks that are configured on the controller. so far this fetches the right volumes and disks in each volume, but doesnt properly fill in the status, the size of both the volumes and disks, the type of raid, or the firmware version of the physical disks.
2006-08-20	stash a pointer to the scsibus attached to us. we can use this later to	David Gwynne
	find the names of our volumes.
2006-08-20	definitions of the messages for raid, volume, and physical disks	David Gwynne

2006-08-20	get rid of the horror that was the ARC_FW_MSG macro	David Gwynne

2006-08-20	get rid of the old arc_msgbuf.	David Gwynne

2006-08-20	cut the rest of the bioctl alarm stuff over to the new arc_msgbuf	David Gwynne

2006-08-20	because the header on firmware commands causes the rest of the message to	David Gwynne
	be unaligned we basically need to bounce the contents of the message in and out of what is submitted to the hardware. rather than have the callers of arc_msgbuf do that, make arc_msgbuf do it for them. while we're here, make arc_msgbuf do the checksumming and length checks so the callers dont have to do that either. this adds an alternative to arc_msgbuf that does the new functionality and cuts arc_bio_alarm_state over to using it. i'll cut the other users of arc_msgbuf over shortly and remove the old implementation.
2006-08-18	oops, debug cruft shouldnt go into the tree.	David Gwynne

2006-08-18	add the sysinfo struct, and then use it to get the current state of the	David Gwynne
	alarm.
2006-08-18	easy bio bits first. this is is code that should enable, disable, and	David Gwynne
	silence the alarm. the hardware can also report the state of the alarm, but its embedded in a really large message im not 100% sure about yet.
2006-08-18	arc, meet bio. bio, meet arc.	David Gwynne

2006-08-18	fix up the arc fw message macros a bit. change a comment while here.	David Gwynne

2006-08-18	a bit more infrastructure for firmware commands.	David Gwynne

2006-08-17	dont need debug in the tree	David Gwynne

2006-08-17	man, i wish firmware commands were as easy as scsi io's on these	David Gwynne
	controllers. this is horrible code that is set up to allow a process, (eg and ioctl or the sensor thread) to issue a command and get a response.
2006-08-15	when there's normal sense data i think the command completed ok, there's	David Gwynne
	just extra data. say there's no residual if that's the case.
2006-08-15	try to deal appropriate with errors from the io command reply	David Gwynne

2006-08-14	start and stop bgrb during attach and detach respectively. as a bonus	David Gwynne
	flush the hbas cache on detach as well. writes on my raid5 seem to run fast now.
2006-08-14	firmware commands (as opposed to io commands) are sent to the firmware via	David Gwynne
	the IOC_WBUF area in bus_space, and replies to it are read from the IOC_RBUF area. the freebsd and linux drivers define these areas to be 32 dwords in length, but it then goes and casts these spaces to a struct that has a 4 byte word at the start with the length of the message in it, followed by a 124 byte buffer which is filled with the actual message in it. rather than screwing around with an extra struct and casts, we can define this header as a register of its own, and the buffer as a separate region in bus_space. this simplifies command submission and the retrieval of the replies (which is yet to be written properly).
2006-08-09	define the size of regions in the register space in terms of bytes, not	David Gwynne
	dwords
