* This is a major rework of the ATA driver (ATAng)Søren Schmidt2003-08-241-28/+40
| | | | | | | | | | | | | | | | | | | | | | | | | Restructure the way ATA/ATAPI commands are processed, use a common ata_request structure for both. This centralises the way requests are handled so locking is much easier to handle. The driver is now layered much more cleanly to seperate the lowlevel HW access so it can be tailored to specific controllers without touching the upper layers. This is needed to support some of the newer semi-intelligent ATA controllers showing up. The top level drivers (disk, ATAPI devices) are more or less still the same with just corrections to use the new interface. Pull ATA out from under Gaint now that locking can be done in a sane way. Add support for a the National Geode SC1100. Thanks to Soekris engineering for sponsoring a Soekris 4801 to make this support. Fixed alot of small bugs in the chipset code for various chips now we are around in that corner anyways. Notes: svn path=/head/; revision=119404

* First round off updates/fixes to the ATA driver.Søren Schmidt2003-02-201-13/+17
| | | | | | | | | | | | | | | This moves all chipset specific code to a new file 'ata-chipset.c'. Extensive use of tables and pointers to avoid having the same switch on chipset type in several places, and to allow substituting various functions for different HW arch needs. Added PIO mode setup and all DMA modes. Support for all known SiS chipsets. Thanks to Christoph Kukulies for sponsoring a nice ASUS P4S8X SiS648 based board for this work!

| | | | | | | | | | | | | | | | doesn't give them enough stack to do much before blowing away the pcb. This adds MI and MD code to allow the allocation of an alternate kstack who's size can be speficied when calling kthread_create. Passing the value 0 prevents the alternate kstack from being created. Note that the ia64 MD code is missing for now, and PowerPC was only partially written due to the pmap.c being incomplete there. Though this patch does not modify anything to make use of the alternate kstack, acpi and usb are good candidates. Reviewed by: jake, peter, jhb Notes: svn path=/head/; revision=104354

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add support for creating/deleting ATA RAID's.Søren Schmidt2002-03-271-99/+315
| | | | | | | | | | | | | | | | | This completes the ATA RAID support, since all functions to manipulate the RAID are accessible from FreeBSD, the BIOS on the ATA RAID cards are only nessesary for booting. I decided to allow for creation of ATA RAID's on any ATA controller, but please keep in mind the restrictions on that. Due to the BIOS not knowing what to do you can only boot from a RAID1 or the first disk in a SPAN, if its not located on a "real" ATA RAID controller like the Promise or Highpoint controllers.

| | | | | | | | | | | | | | | | by removing parentheses. The main bug is in gcc: on machines with 64-bit longs and 64-bit long longs, (unsigned long long)rdp->total_sectors / ((1024L * 1024L) / DEV_BSIZE)) has type plain unsigned long instead of the correctly promoted type unsigned long long, so it can not be printfed using %llu format. Even 1ULL / 1L is mispromoted. Anyway, casting the correct operand automatically avoids the problem. We do not want to to pessimize the division; we just want to convert to a common maximal type for printing. Notes: svn path=/head/; revision=91729

* Major update of the ATA RAID code, part 3:Søren Schmidt2002-03-031-224/+359
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add code to properly detach/attach disks that are part of a RAID. Mark a disk that is attached on an ATA channel belonging to a RAID as a spare disk that can be used for rebuilding failed RAID1's. Add support for rebuilding failed RAID1's. Several fixes to the detach/attach code. For replacing a disk in a failed RAID1 do the following: Find the controller channel# of the failed disk. Exec 'atacontrol detach <channel#>' to free the disk from the system. Replace the failed disk with a new one of at least the same size. If your have your disks in drawers/enclosures this can be done with the system still running. Exec 'atacontrol attach <channel#>' to add the disk to the system and mark it as a valid spare for rebuild. Exec 'atacontrol rebuild <array#>' The system will rebuild the array on the fly, the array can still be used during this, although with slower performance. Please let me know of any problems with this! Sponsored by: Advanis Inc. MFC after: 2 weeks Notes: svn path=/head/; revision=91593

* Major update of the ATA RAID code, part 1:Søren Schmidt2002-02-041-268/+476
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overhaul of the attach/detach code and structures, there were some nasty bugs in the old implementation. This made it possible to collapse the ATA/ATAPI device control structures into one generic structure. A note here, the kernel is NOT ready for detach of active devices, it fails all over in random places, but for inactive devices it works. However for ATA RAID this works, since the RAID abstration layer insulates the buggy^H^H^H^H^H^Hfragile device subsystem from the physical disks. Proberly detect the RAID's from the BIOS, and mark critical RAID1 arrays as such, but continue if there is enough of the mirror left to do so. Properly fail arrays on a live system. For RAID0 that means return EIO, and for RAID1 it means continue on the still working part of the mirror if possible, else return EIO. If the state changes, log this to the console. Allow for Promise & Highpoint controllers/arrays to coexist on the same machine. It is not possible to distribute arrays over different makes of controllers though. If Promise SuperSwap enclosures are used, signal disk state on the status LED on the front. Misc fixes that I had lying around for various minor bugs. Sponsored by: Advanis Inc.
