2006-10-21[PATCH] cciss: Fix warnings (and bug on 1TB discs)Matthew Wilcox1-13/+9
CCISS was producing warnings about shifts being greater than the size of the type and pointers being of incompatible type. Turns out this is because it's calling do_div on a 32-bit quantity. Upon further investigation, the sector_t total_size is being assigned to an int, and then we're calling do_div on that int. Obviously, sector_div is called for here, and I took the chance to refactor the code a little.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-3/+3
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.

2006-01-08[PATCH] cciss: adds MSI and MSI-X supportMike Miller1-11/+76
This creates a new function, cciss_interrupt_mode called from cciss_pci_init. This function determines what type of interrupt vector to use, i.e., MSI, MSI-X, or IO-APIC. One noticeable difference is changing the interrupt field of the controller struct to an array of 4 unsigned ints. The Smart Array HW is capable of generating 4 distinct interrupts depending on the transport method in use during operation. These are: #define DOORBELL_INT 0 Used to notify the contoller of configuration updates. We only use this feature when in polling mode. #define PERF_MODE_INT 0 Used when the controller is in Performant Mode. #define SIMPLE_MODE_INT 2 Used when the controller is in Simple Mode (current Linux implementation). #define MEMQ_INT_MODE 3 Not used. When using IO-APIC interrupts these 4 lines are OR'ed together so when any one fires an interrupt an is generated. In MSI or MSI-X mode this hardware OR'ing is ignored. We must register for our interrupt depending on what mode the controller is running. For Linux we use SIMPLE_MODE_INT exclusively at this time. Please consider this for inclusion.

2006-01-08[PATCH] Add block_device_operations.getgeo block device methodChristoph Hellwig1-15/+16
HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.
