2006-10-01[SCSI] scsi_devinfo: add TornadoMike Christie1-0/+1
This is from RHEL4. I do not have any info from our bugzilla. All I could find was something like this thread http://lkml.org/lkml/2005/1/7/346 Report lun for linux does not work. It may be our lun format code or it may be the device. It is probably not worth it to add anything special for this device, so the patch just adds BLIST_NOREPORTLUN.

2006-09-30[PATCH] BLOCK: Make it possible to disable the block layer [try #6]David Howells1-0/+2
Make it possible to disable the block layer. Not all embedded devices require it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require the block layer to be present. This patch does the following: (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev support. (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls an item that uses the block layer. This includes: (*) Block I/O tracing. (*) Disk partition code. (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS. (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the block layer to do scheduling. Some drivers that use SCSI facilities - such as USB storage - end up disabled indirectly from this. (*) Various block-based device drivers, such as IDE and the old CDROM drivers. (*) MTD blockdev handling and FTL. (*) JFFS - which uses set_bdev_super(), something it could avoid doing by taking a leaf out of JFFS2's book. (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is, however, still used in places, and so is still available. (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and parts of linux/fs.h. (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK. (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK. (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK is not enabled. (*) fs/no-block.c is created to hold out-of-line stubs and things that are required when CONFIG_BLOCK is not set: (*) Default blockdev file operations (to give error ENODEV on opening). (*) Makes some /proc changes: (*) /proc/devices does not list any blockdevs. (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK. (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK. (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if given command other than Q_SYNC or if a special device is specified. (*) In init/do_mounts.c, no reference is made to the blockdev routines if CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2. (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return error ENOSYS by way of cond_syscall if so). (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if CONFIG_BLOCK is not set, since they can't then happen.

2006-09-30[PATCH] SCSI: scsi_done_q is unusedJens Axboe1-10/+1

2006-09-30[PATCH] Remove ->rq_status from struct requestJens Axboe2-2/+2
After Christophs SCSI change, the only usage left is RQ_ACTIVE and RQ_INACTIVE. The block layer sets RQ_INACTIVE right before freeing the request, so any check for RQ_INACTIVE in a driver is a bug and indicates use-after-free. So kill/clean the remaining users, straight forward.

2006-09-30[PATCH] Split struct request ->flags into two partsJens Axboe8-36/+36
Right now ->flags is a bit of a mess: some are request types, and others are just modifiers. Clean this up by splitting it into ->cmd_type and ->cmd_flags. This allows introduction of generic Linux block message types, useful for sending generic Linux commands to block devices. Signed-off-by: Jens Axboe <axboe@suse.de>
2006-09-27[PATCH] EISA bus MODALIAS attributes supportMichael Tokarev3-1/+4
Add modalias attribute support for the almost forgotten now EISA bus and (at least some) EISA-aware modules. The modalias entry looks like (for an 3c509 NIC): eisa:sTCM5093 and the in-module alias like: eisa:sTCM5093* The patch moves struct eisa_device_id declaration from include/linux/eisa.h to include/linux/mod_devicetable.h (so that the former now #includes the latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE declared), and adds recognision of __mod_eisa_device_table to scripts/mod/file2alias.c so that proper modules.alias will be generated. There's no support for /lib/modules/$kver/modules.eisamap, as it's not used by any existing tools, and because with in-kernel modalias mechanism those maps are obsolete anyway. The rationale for this patch is: a) to make EISA bus to act as other busses with modalias support, to unify driver loading b) to foget about EISA finally - with this patch, kernel (who still supports EISA) will be the only one who knows how to choose the necessary drivers for this bus ;) [akpm@osdl.org: fix the kbuild bit] Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Randy Dunlap <rdunlap@xenotime.net> Acked-the-net-bits-by: Jeff Garzik <jeff@garzik.org> Acked-the-tulip-bit-by: Valerie Henson <val_henson@linux.intel.com> Cc: James Bottomley <James.Bottomley@steeleye.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-09-26[SCSI] megaraid: Use the proper type to hold the irq number.Eric W. Biederman1-1/+1
When testing on a Unisys machine it was discovered that the megaraid driver would not initialize as it was requesting irq 162 instead of irq 1442 it was assigned. The problem was the irq number had been truncated by being stored in an unsigned char. This patches fixes that problem and the driver now appears to work.

2006-09-26[SCSI] sg: fixes for large page_sizeDouglas Gilbert1-13/+40
This sg driver patch addresses the problem with larger page sizes reported by Brian King in this post: http://marc.theaimsgroup.com/?l=linux-scsi&m=115867718623631&w=2 Some other related matters are also addressed. Some of these prevent oopses when the SG_SCATTER_SZ or scatter_elem_sz are set to inappropriate values. The scatter_elem_sz has been tested up to 4 MB which should make the largest data transfer with one SCSI command, 32 MB less one block, achievable with a relatively small number of elements in the scatter gather list. ChangeLog: - add scatter_elem_sz boot time parameter and sysfs module parameter that is initialized to SG_SCATTER_SZ - the driver will then adjust scatter_elem_sz to be the max(given(scatter_elem_sz), PAGE_SIZE) It will also round it up, if necessary, to be a power of two - clean up sg.h header, correct bad urls and some statements that are no longer valid - make the def_reserved_size sysfs module attribute writable Signed-off-by: Douglas Gilbert <dougg@torque.net> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-09-25fix broken/dubious driver suspend() methodsDavid Brownell1-4/+11
Small driver suspend() fixes in preparation for the PRETHAW events: - Only compare message events for equality against PM_EVENT_* codes; not against integers, or using greater/less-than comparisons. (PM_EVENT_* should really become a __bitwise thing.) - Explicitly test for SUSPEND events (rather than not-something-else) before suspending devices. - Removes more of the confusion between a pm_message_t (wraps event code) and a "state" ... suspend() originally took a target system state. These updates are correct and appropriate even without new PM_EVENT codes. benh: "I think in the Mesh case, we should handle the freeze case as well or we might get wild DMA."

Received from Mark Salyzyn: I am placing this functionality into an insmod parameter. Normally the physical components are exported to sg, and are blocked from showing up in sd. Note that the pass-through I/O path via the driver through the Firmware to the physical disks is not an optimized path, the card is designed for Hardware RAID, elevator sorting and caching. This should not be used as a means for utilizing the aacraid based controllers as a generic scsi/SATA/SAS controller, performance should suck by a few percentage points, any RAID meta-data on the drives will confuse the controller about who owns the drives and there is a high risk of destroying content in both directions.
