2008-04-07[SCSI] aic7xxx: Test opcode, not definition in aicasm:type_check()Roel Kluin
This fixes a bug that we treat all sequencer operations as ands and never do the additional invalid bit checks non-and operations require because the if () to determine this has an operand which is always true at the end of the or statement.

2008-02-23PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki
During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

2008-02-18[SCSI] aic7xx: mitigate HOST_MSG_LOOP invalid SCB ff panicJames Bottomley
The panic occurs if we get a MSGIN or MSGOUT for an unidentified SCB (meaning we didn't identify the outstanding command it was for). For MSGIN this is wrong because it could be an unsolicited negotiation MSGIN from the target. Still panic on unsolicited MSGOUT because this would represent a mistake in the negotiation phases. However, we should fix this as well. The specs say we should go to bus free for unexpected msgin. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

2008-02-03scsi: fix dependency bug in aic7 MakefileSam Ravnborg
Building the aic7xxx driver includes the copy of an .h file from a _shipped file. In a highly parallel build Ingo saw that the build sometimes failed (included distcc usage). It was tracked down to a missing dependency from the .c source file to the generated .h file. We started to build the .c file before the copy (cat) operation of the .h file completed and we then only got half of the definitions from the copied .h file. Add an explicit dependency from the .c files to the generated .h files so make knows all dependencies and finsih the build of the .h files before it starts building the .o files. Ingo tested this fix and reported: good news: hundreds of successful kernel builds and no failures overnight.

2008-01-30[SCSI] remove use_sg_chainingJames Bottomley
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.

That means that my parser tries to parse all the code, including code in the #else branch or code that is not often compiled because the driver is not very used (or not used at all).

Whenever an external device is resetted we really have to take care to keep the channel in sync. Just notifying SCSI-ML and retry is not enough as we have to make sure the SCSI bus is not getting confused, either. So whenever we detect an external reset we rewrite the command to TUR, disable packetized command and notify the internal engine that an abort has happened. This way we trigger a proper bus reset sequence and all devices will be renegotiated properly. Kudos to Justin Gibbs and Luben Tuikov for this idea.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.
