* Change the disk(9) API in order to make device removal more robust.phk2004-02-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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 bioq_flush() to drain a bio queue with a specific error code.phk2003-04-011-0/+1
| | | | | | | | Retain the mistake of not updating the devstat API for now. Spell bioq_disksort() consistently with the remaining bioq_*(). #include <geom/geom_disk.h> where this is more appropriate.
* Centralize the devstat handling for all GEOM disk device driversphk2003-03-081-1/+0
| | | | | | | | in geom_disk.c. As a side effect this makes a lot of #include <sys/devicestat.h> lines not needed and some biofinish() calls can be reduced to biodone() again.

(2) Problem: PANIC when unloading driver as module. Fix - device nodes are not destroyed for amr0, and amrd* when driver is unloaded (3) Problem: PANIC from loading driver when 3ware adapter present, error message "Warning "amrd is usurping twed's bmaj" Fix - put #idef freebsd version < 500000 for bmaj -1 -> amrd_cdevsw (4) Problem: warnings in driver when compiling with DAMR_DEBUG param enabled in Makefile Fix - fix the warnings so driver can compile when -Werror is present in Makefile.

* Make FreeBSD "struct disklabel" agnostic, step 311 of 723:phk2002-09-201-1/+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.

* Major update to the AMI MegaRAID driver.msmith2000-08-301-98/+194
| | | | | | | | | | | | | | | | - New support for 40LD firmware found in Series 475 and 471 adapters. - Better support for 8LD firmware adapters - Ioctl passthrough interface for userland utilities. - Improved error handling and queueing. - Several bugfixes (including the 'still open' shutdown bug and closing some small race conditions). - Zone-style command allocator, reducing memory wasted under heavy load conditions. - CAM interface (disabled and not fully working) for SCSI passthrough access to non-disk devices Thanks to AMI for supplying a pile of new adapters and various other help in making this happen.

* Update to latest working version.msmith2000-04-011-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add periodic status monitoring routine. Currently just detects lost commands, further functionality pending data from AMI. Add some new commands states; WEDGED (never coming back) and LATE (for when a command that wasmarked as WEDGED comes bacj, - Remove a number of redundant efforts to poll the card for completed commands. This is what interrupt handlers are for. - Limit the maximum number of outstanding I/O transactions. It seems that some controllers report more than they can really handle, and exceding this limit can cause the controller to lock up. - Don't use 'wait' mode for anything where the controller might not be able to generate interrupts. (Keep the 'wait' mode though sa it will become useful when we start taking userspace commands. - Use a similar atomic locking trategy to the Mylex driver to prevent some reentrancy problems. - Correctly calculate the block count for non-whoile-bloch transfers (actually illegal). - Use the dsik device's si_drv1 field instead of b_driver1 in the buf struct to pass the driver identifier arond. - Rewrite amr_start and amr_done() along the lines of the Mylex driver in order to improve robustnes. - Always force the PCI busmaster bit on.
