| * [SCSI] mptsas: Fix oops for insmod during kexecJudith Lebzelter2007-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fix's an oops during driver load time. mptsas_probe calls mpt_attach(over in mptbase.c). Inside that call, we read some manufacturing config pages to setup some defaults. While reading the config pages, the firmware doesn't complete the reply in time, and we have a timeout. The timeout results in hardreset handler being called. The hardreset handler calls all the fusion upper layer driver reset callback handlers. The mptsas_ioc_reset function is the callback handler in mptsas.c. So where I'm getting to, is mptsas_ioc_reset is getting called before scsi_host_alloc is called, and the pointer ioc->sh is NULL as well as the hostdata.

* | [PATCH] i2o: block IO errors on i2o diskVasily Averin2007-03-27
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | I2O subsystem has been broken in mainstream several months ago (after 2.6.18). Commit 4aff5e2333c9a1609662f2091f55c3f6fffdad36 from Jens Axboe split struct request ->flags into two parts: cmd_type and cmd_flags. In i2o layer this patch has replaced flag REQ_SPECIAL by the according cmd_type. However i2o has used REQ_SPECIAL not as command type but as driver-specific flag for the debug purposes. As result all i2o requests have type "special" now, are not processed to the hardware and fail with I/O error: i2o/hda:<3>Buffer I/O error on device i2o/hda, logical block 0 Buffer I/O error on device i2o/hda, logical block 0 Buffer I/O error on device i2o/hda, logical block 0 unable to read partition table block-osm: device added (TID: 207): i2o/hda The following patch removes the extra debug checks without any drawbacks and restores the normal driver's work.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* [SCSI] fusion - serialize target resets in mptsas.cEric Moore2007-02-02
| | | | | | | | | | | | | Fusion firmware requires target reset following hotplug removal event, with purpose to flush target outstanding request in fw. Current implementation does the target resets from delayed work tasks, that in heavy load conditions, take too long to be invoked, resulting in command time outs This patch will issue target reset immediately from ISR context, and will queue remaining target resets to be issued after the previous one completes.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

* | [PATCH] BLOCK: Make it possible to disable the block layer [try #6]David Howells2006-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | [PATCH] Split struct request ->flags into two partsJens Axboe2006-09-30
|/ | | | | | | | | | 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>
* [SCSI] scsi_transport_sas: remove local_attached flagJames Bottomley2006-08-27
| | | | | | | | | | | | | | | | | This flag denotes local attachment of the phy. There are two problems with it: 1) It's actually redundant ... you can get the same information simply by seeing whether a host is the phys parent 2) we condition a lot of phy parameters on it on the false assumption that we can only control local phys. I'm wiring up phy resets in the aic94xx now, and it will be able to reset non-local phys as well. I fixed 2) by moving the local check into the reset and stats function of the mptsas, since that seems to be the only HBA that can't (currently) control non-local phys.

| * [SCSI] mptfc: correct out of order event processingMichael Reed2006-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch corrects a problem in mptfc which can result in targets being removed after executing an "lsiutil 99" reset of the fibre channel ports. The last rescan event was being processed before the setup reset work due to an inappropriate optimization in the event processing logic. Every rescan event is now queued for execution and the setup reset work now executes in the proper sequence.
