* (This commit touches about 15 disk device drivers in a very consistentPoul-Henning Kamp2002-09-201-10/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and predictable way, and I apologize if I have gotten it wrong anywhere, getting prior review on a patch like this is not feasible, considering the number of people involved and hardware availability etc.) If struct disklabel is the messenger: kill the messenger. Inside struct disk we had a struct disklabel which disk drivers used to communicate certain metrics to the disklayer above (GEOM or the disk mini-layer). This commit changes this communication to use four explicit fields instead. Amongst the benefits is that the fields do not get overwritten by wrong or bogus on-disk disklabels. Once that is clear, <sys/disk.h> which is included in the drivers no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in, the few places that needs them, have gotten explicit #includes for them. The disklabel inside struct disk is now only for internal use in the disk mini-layer, so instead of embedding it, we malloc it as we need it. This concludes (modulus any mistakes) the series of disklabel related commits. I belive it all amounts to a NOP for all the rest of you :-) Sponsored by: DARPA & NAI Labs.

* Make FreeBSD "struct disklabel" agnostic, step 311 of 723:Poul-Henning Kamp2002-09-201-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename diskerr() to disk_err() for naming consistency. Drop the by now entirely useless struct disklabel argument. Add a flag argument for new-line termination. Fix a couple of printf-format-casts to %j instead of %l. Correctly print the name of all bio commands. Move the function from subr_disklabel.c to subr_disk.c, and from <sys/disklabel.h> to <sys/disk.h>. Use the new disk_err() throughout, #include <sys/disk.h> as needed. Bump __FreeBSD_version for the sake of the aac disk drivers #ifdefs. Remove unused disklabel members of softc for aac, amr and mlx, which seem to originally have been intended for diskerr() use, but which only rotted and got Copy&Pasted at least two times to many.

* Remove B_READ, B_WRITE and B_FREEBUF and replace them with a newPoul-Henning Kamp2000-03-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | field in struct buf: b_iocmd. The b_iocmd is enforced to have exactly one bit set. B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes. Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL. Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading. This change is a step in the direction towards a stackable BIO capability. A lot of this patch were machine generated (Thanks to style(9) compliance!)

* Update to the latest development version of the Mylex driver. Changes inMike Smith2000-03-186-162/+704
| | | | | | | | | | | | | | | | | | | | | this version include: - Support for version 2.x firmware (2.42 or later recommended). This means we are the only open-source driver supporting these adapters. This code has only been tested on a Digital KZPCA adapter in an Alpha system, but is believed to be correct. NOTE: EISA adapters are not yet supported. - Support the BIOS/Firmware initialisation handshake protocol. This allows the driver to bring the card up to operational state even if the BIOS can't be run (eg. if it's an x86 BIOS in an Alpha system). - A working command pasthrough interface. This allows a user-space configuration tool (under development) to issue arbitrary commands to the controller or to devices in the system. Notes: svn path=/head/; revision=58188

* Updates resulting from new documentation from Mylex and some cleaning:Mike Smith1999-12-224-75/+95
| | | | | | | | | | | | | | | | | | | | | - Don't keep private copies of some of the data fields from the ENQUIRY and ENQUIRY2 commands. Instead, standardise on the ENQUIRY2 command for initial adapter information, and keep a copy of the entire structure. Refer to it where appropriate. - Move all of the controller description functionality into a new function. Print lots more controller data if bootverbose is set. Add knowledge of the DAC960 PR, PT, PTL0 and PRL controllers, rename the 960PTL -> PTL0 and 1100P -> 1100PVX. - Correctly terminate an error message. The controller interface procedures have been reviewed against the Mylex-supplied documentation; no changes appear necessary at this time. Notes: svn path=/head/; revision=54979

* Major update to the Mylex DAC960 driver adding new hardware supportMike Smith1999-12-115-174/+305
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and fixing some major bugs. - Add support for the v5 firmware interface, used by the DAC1164P (tested) and AcceleRAID 352 (untested but should work). We now cover all of the Mylex family's protocols except for v2 (used by EISA and Alpha-compatible cards). - Fix an accounting bug which resulted in endless 'poll still busy' messages. In situations of high controller load the count of poll commands could be incremented without actually successfully launching a command. This totally removes the accounting for status poll commnads; it was its own worst enemy. - Add some simple reentry prevention locks to processing of the waiting and completed command queues to prevent races which could result in I/O being done or completed twice (both are fatal). This highlights a need for simple locking primitives in both the UP and SMP kernels. - Streamline the handling of command completion to reduce the amount of redundant work being done. Remove the code which tests for commands that have gone missing in action; nobody has ever seen one of these and it wouldn't have worked properly anyhow. - Handle disconnection of drives from the controller in the detach, not shutdown method. This avoids problems flushing the cache in a panic when a drive is mounted. - Don't call bus_generic_detach when disconnecting drives; it doesn't actually do anything useful. - Increment the log message index regardless of whether we actually retrieved one or not. If we run into a message that we can't fetch, we don't want to spin endlessly complaining about the fact. - Don't assume that interrupts will work when we're flushing the controller. We may think they are enabled, but in eg. a panic situation the controller may not be able to deliver an interrupt. Notes: svn path=/head/; revision=54419
* Revamp the devstat priority system. All disks now have the same priority.Kenneth D. Merry1999-12-081-2/+2
| | | | | | | | | | | | | | | | | | | | | The same goes for CD drivers and tape drivers. In systems with mixed IDE and SCSI, devices in the same priority class will be sorted in attach order. Also, the 'CCD' priority is now the 'ARRAY' priority, and a number of drivers have been modified to use that priority. This includes the necessary changes to all drivers, except the ATA drivers. Soren will modify those separately. This does not include and does not require any change in the devstat version number, since no known userland applications use the priority enumerations.

This makes it easier for us to change how arbitrary data structures are associated with a device_t. Eventually we won't be modifying device_t to add additional pointers for ivars, softc data etc. Despite my best efforts I've probably forgotten something so let me know if this breaks anything.
