* Change the disk(9) API in order to make device removal more robust.phk2004-02-181-20/+23
| | | | | | | | | | | | | | | | | | | | | | | | Previously the "struct disk" were owned by the device driver and this gave us problems when the device disappared and the users of that device were not immediately disappearing. Now the struct disk is allocate with a new call, disk_alloc() and owned by geom_disk and just abandonned by the device driver when disk_create() is called. Unfortunately, this results in a ton of "s/\./->/" changes to device drivers. Since I'm doing the sweep anyway, a couple of other API improvements have been carried out at the same time: The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to DISKFLAG_NEEDSGIANT A version number have been added to disk_create() so that we can detect, report and ignore binary drivers with old ABI in the future. Manual page update to follow shortly.

* Use UMA instead of plain malloc for getting ATA request storage.sos2004-01-141-0/+1
| | | | | | | This gives +10% performance on simple tests, so definitly worth it. A few percent more could be had by not using M_ZERO'd alloc's, but we then need to clear fields all over the place to be safe, and that was deemed not worth the trouble (and it makes life dangerous).
* Overhaul of the timeout/reinit framework. This should clear up mostsos2004-01-111-4/+5
| | | | | | | | | | | | of the leftovers from the old version that really doesn't work anymore. Add a reset function for host-end of the ATA channel. This is needed for the SiI3112 in order to whack it back to reality if a device locks up the SATA interface (thereby preventing that we can reset the device). The result is that ATA now recovers from the timeouts that happens with the SiI3112A and more or less all disks based on old PATA electronics with a Marvell PATA->SATA converter. This includes lots of the popular SATA dongles and the WDC Raptor disks..

* This is a major rework of the ATA driver (ATAng)sos2003-08-241-28/+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.

* First round off updates/fixes to the ATA driver.sos2003-02-201-13/+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

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.sos2002-03-271-99/+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.
