With the sg table code, every SCSI driver is now either chain capable or broken (or has sg_tablesize set so chaining is never activated), so there's no need to have a check in the host template. Also tidy up the code by moving the scatterlist size defines into the SCSI includes and permit the last entry of the scatterlist pools not to be a power of two.

Wide transfers are required for every setting of PPR apart from QAS. It seems the DV code starts at the minimum, which turns on DT and Wide regardless of the setting of max_width.

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.

To transport scsi reset command to device aic7xxx reset handler looks at the driver's pending_list and searches any proper command. However the search condition has been inverted: ahc_match_scb() returns TRUE if a matched command is found. As a result the reset on required devices did not turn out well, a correctly working neighbour device may be surprised by the reset. aic7xxx reset handler reports about the success, but really the original situation is not corrected yet.

In these drivers, scsi_remove_host() is called too late, at the point it is called, the driver has already shut down too far to accept any I/O that the shutdown might generate.

This patch moves aic7xxx over to the dma_get_required_mask() API and dumps its open coded memory check. It also appears from this bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=167049 That 39 bit addressing doesn't work on older cards. I surmise that the AHC_LARGE_SCBS flag is the one that marks cards capable of using 39 bit addressing, so I also folded that check into the code.

Several people noticed we dropped quite a bit on benchmark figures. OK, it was my fault but unfortunately I discovered I ran out of brown paper bags a while ago and forgot to reorder them. The issue is that a construct introduced in the conversion of the driver to use the transport class keyed off whether the block request was tagged or not. However, the aic7xxx driver doesn't properly set up the block layer TCQ (it uses the wrong API), so the driver now things all requests are untagged and we keep it to a queue depth of a single element. Oops. The fix is to use the correct TCQ API. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>
