| * [SCSI] ipr: Fix for oops following SATA request senseBrian King2007-04-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem discovered on a system with some bad SATA devices attached. If a command to a SATAPI device times out and the device gets reset as part of error recovery, its possible that ipr will set err_mask to indicate a device error has occurred. If this happens, a request sense will get issued by libata. Since scsi core thinks this scsi command is now completed, because the device reset handler completed successfully, scsi core will free the associated scsi command, which may cause an oops when that request sense is completed later by ipr. This patch ensures that any commands that get aborted as a result of a device reset set err_mask appropriately so that the request sense does not get sent.

| * [SCSI] ipr: Enable logging of debug error data for all devicesBrian King2007-04-011-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | The ipr driver has a sysfs attribute which can be used to adjust the logging level of the driver for error events. The error response data for commands can be dumped by increasing the logging level of the ipr driver. This currently only works for JBOD passthrough devices. This patch enables this function for all devices, including RAID devices, to aid in debugging problems.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The netlink layer got a nice generic interface with named slots recently, which is probably a better facility to plug events for subsystem specific events. Also the new poll() interface to /proc/mounts is a nicer way to notify about changes than sending events through the core.

|/ | | | | | | | | | | | | | | | When kexec booting a kernel when the previous kernel did not call ipr's shutdown method, the ipr adapter does not get properly initialized, which can result in the ipr adapter completing commands issued by the previous kernel.

If the interrupt mask register indicates that interrupts are enabled or the reset alert bit is set when the card is probed, this means the card is in an unknown state and we hard reset the card.
