* [SCSI] qla4xxx: Handle outstanding mbx cmds on hung f/w scenariosNilesh Javali2010-08-061-0/+1
| | | | | | | | | | | | | | | | | | | | | Outstanding mailbox commands, have no way to recover on f/w hung, and we timeout on waiting for mbx response. This in turn affects the recovery process as follows: - We might already be in dpc while waiting for mbx to complete, so recovery for that pci function will never get invoked. Reset Timeout (10 sec) is far less than mbx timeout (30 sec). - Other mbx cmds will get stuck due to serial mbx access. Solution is to identify fw-hung scenario and handle outstanding mbx commands to have an early-exit instead of waiting for response. Other mbx commands waiting for access will also do an early-exit if fw-hung is still applicable.

| | | | | | | | | | | | | | This patch contains the following: 1. when hba completion status is good, check for iscsi transport errors (underflow/overflow) prior to checking the scsi status 2. New firmware requires that one marker iocb be issued for each task management command. The patch issues marker iocb immediately following a LUN or Target reset.

* [SCSI] qla4xxx: bug fixesDavid C Somayajulu2007-01-271-0/+1
| | | | | | | | | | | | | | | | | The included patch fixes the following issues: 1. qla3xxx/qla4xxx co-existence issue which can result in a lockup when qla3xxx driver is unloaded, or when ifdown; ifup is performed on one of the interfaces correponding to qla3xxx. This is because qla4xxx HBA supports one ethernet and iscsi interfaces per port. Both iscsi and ethernet interfaces share the same state machine. The problem has to do with synchronizing access to the state machine in the event of a reset 2. mutex_lock() is sometimes not followed by mutex_unlock() prior to invoking a msleep() in qla4xxx_mailbox_command() Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

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.
