| 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. | |||

| 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 | |||
| 2006-08-07 | whitespace fixes | David Gwynne | |
| 2006-08-07 | from the drivers side of the iop331 there is only one set of interrupt | David Gwynne | |
| registers to deal with, the other set are used on the firmware side of the device. shrink a bit by removing the definitions of the firmwares registers. | |||
| 2006-08-06 | endian fixes. this works on sparc64 now. | David Gwynne | |
| 2006-08-06 | fill out the interrupt handler. io is now no longer polled, and as a bonus | David Gwynne | |
| it's fairly fast :) | |||
| 2006-08-06 | we can support more than one entry in an sgl, so stop lying to bus_dma | David Gwynne | |
| 2006-08-06 | less magic | David Gwynne | |
| 2006-08-06 | io commands are the only ones every posted on the queues, so hardcode the | David Gwynne | |
| type into the ccb rather than use void *s and insane casting to get at bits of the command. | |||
| 2006-08-05 | implement reply and post queue handling, but only polled for now. io should | David Gwynne | |
| work with this, but i cant test without disks. | |||
| 2006-08-03 | white space fixes | David Gwynne | |
| 2006-07-31 | take a scsi xfer from the midlayer and turn it into an areca io command. | David Gwynne | |
| its inside an if 0 chunk till i write the post and reply queue handling and the response handling. | |||
| 2006-07-31 | hook arc up to the scsi midlayer | David Gwynne | |
