* mpr/mps(4): Make device mapping some more robust.Alexander Motin2021-04-241-26/+45
| | | | | | | | | | | | | | | | | | | | Allow new enclosure to replace previously existing one if there is no completely unused table entry, same as it is done for devices. If we can not process DPM due to corruption -- wipe it and restart from scratch. Otherwise I don't see a way to recover persistence if something go wrong and there is no BIOS to recover it for us. Together this solves a problem that appeared when 9300-8i firmware update to 16.00.10.00 somehow switched its mapping mode from Device Persistence to Enclosure/Slot without wiping the DPM table. It made HBA completely unusable, since overflowed and conflicting mapping table was unable to map any of enclosures and so devices. Also while there make some enclosure mapping errors more informative. MFC after: 1 month Sponsored by: iXsystems, Inc.

| | | | | | | | | | | | | | | | | | Uses of mallocarray(9). The use of mallocarray(9) has rocketed the required swap to build FreeBSD. This is likely caused by the allocation size attributes which put extra pressure on the compiler. Given that most of these checks are superfluous we have to choose better where to use mallocarray(9). We still have more uses of mallocarray(9) but hopefully this is enough to bring swap usage to a reasonable level. Reported by: wosch PR: 225197 Notes: svn path=/head/; revision=328218
* dev: make some use of mallocarray(9).Pedro F. Giffuni2018-01-131-11/+11
| | | | | | | | | | | | | | Focus on code where we are doing multiplications within malloc(9). None of these is likely to overflow, however the change is still useful as some static checkers can benefit from the allocation attributes we use for mallocarray. This initial sweep only covers malloc(9) calls with M_NOWAIT. No good reason but I started doing the changes before r327796 and at that time it was convenient to make sure the sorrounding code could handle NULL values. Notes: svn path=/head/; revision=327949
* Fix mpr(4) panics caused by bad drive mapping tablesAlan Somers2017-11-031-6/+20
| | | | | | | | | | | | | | | | | sys/dev/mpr/mpr_mapping.c If _mapping_process_dpm_pg0 detects inconsistencies in the drive mapping table (stored in the HBA's NVRAM), abort reading it and continue to boot as if the mapping table were blank. I observed such inconsistencies in several HBAs after upgrading firmware from 14.0.0.0 to 15.0.0.0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Updated all files with 2015 Avago copyright, and updated LSI's copyright dates. - Changed all of the PCI device strings from LSI to Avago Technologies (LSI). - Added a sysctl variable to control how StartStopUnit behavior works. User can select to spin down disks based on if disk is SSD or HDD. - Inquiry data is required to tell if a disk will support SSU at shutdown or not. Due to the addition of mpssas_async, which gets Advanced Info but not Inquiry data, the setting of supports_SSU was moved to the mpssas_scsiio_complete function, which snoops for any Inquiry commands. And, since disks are shutdown as a target and not a LUN, this process was simplified by basing it on targets and not LUNs. - Added a sysctl variable that sets the amount of time to retry after sending a failed SATA ID command. This helps with some bad disks and large disks that require a lot of time to spin up. Part of this change was to add a callout to handle timeouts with the SATA ID command. The callout function is called mpssas_ata_id_timeout(). (Fixes PR 191348) - Changed the way resets work by allowing I/O to continue to devices that are not currently under a reset condition. This uses devq's instead of simq's and makes use of the MPSSAS_TARGET_INRESET flag. This change also adds a function called mpssas_prepare_tm(). - Some changes were made to reduce code duplication when getting a SAS address for a SATA disk. - Fixed some formatting and whitespace. - Bump version of mps driver to 9.255.01.00-fbsd PR: 191348 Reviewed by: ken, scottl Approved by: ken, scottl MFC after: 1 week Notes: svn path=/head/; revision=283661

* Bring in the mpr(4) driver for LSI's MPT3 12Gb SAS controllers.Kenneth D. Merry2014-05-021-0/+2269
This is derived from the mps(4) driver, but it supports only the 12Gb IT and IR hardware including the SAS 3004, SAS 3008 and SAS 3108. Some notes about this driver: o The 12Gb hardware can do "FastPath" I/O, and that capability is included in this driver. o WarpDrive functionality has been removed, since it isn't supported in the 12Gb driver interface. o The Scatter/Gather list handling code is significantly different between the 6Gb and 12Gb hardware. The 12Gb boards support IEEE Scatter/Gather lists. Thanks to LSI for developing and testing this driver for FreeBSD. share/man/man4/mpr.4: mpr(4) man page. sys/dev/mpr/*: mpr(4) driver files. sys/modules/Makefile, sys/modules/mpr/Makefile: Add a module Makefile for the mpr(4) driver. sys/conf/files: Add the mpr(4) driver. sys/amd64/conf/GENERIC, sys/i386/conf/GENERIC, sys/mips/conf/OCTEON1, sys/sparc64/conf/GENERIC: Add the mpr(4) driver to all config files that currently have the mps(4) driver. sys/ia64/conf/GENERIC: Add the mps(4) and mpr(4) drivers to the ia64 GENERIC config file. sys/i386/conf/XEN: Exclude the mpr module from building here.
