2009-09-15[IA64] pci_br, fix infinite loop in find_free_ate()Jiri Slaby1-0/+2
When * there is almost out of ates * one asks for more than one ate * there are some available at the end of ate array then the inner for loop will end without incrementing 'index'. This means the outer loop will start at the same point finding it's available and runs the inner loop again from the same index. This repeats forever. Hence make sure we check we were at the end of ate array and return an error in such case.

2009-06-17[IA64] Convert ia64 to use int-ll64.hMatthew Wilcox3-7/+7
It is generally agreed that it would be beneficial for u64 to be an unsigned long long on all architectures. ia64 (in common with several other 64-bit architectures) currently uses unsigned long. Migrating piecemeal is too painful; this giant patch fixes all compilation warnings and errors that come as a result of switching to use int-ll64.h. Note that userspace will still see __u64 defined as unsigned long. This is important as it affects C++ name mangling.

2009-06-16page allocator: do not check NUMA node ID when the caller knows the node is validMel Gorman1-1/+2
Callers of alloc_pages_node() can optionally specify -1 as a node to mean "allocate from the current node". However, a number of the callers in fast paths know for a fact their node is valid. To avoid a comparison and branch, this patch adds alloc_pages_exact_node() that only checks the nid with VM_BUG_ON(). Callers that know their node is valid are then converted.

2009-01-06set up dma_ops appropriatelyFUJITA Tomonori1-0/+5
This patch introduces a global pointer, dma_ops, which points to an appropriate dma_mapping_ops that the kernel should use. This is a common way to handle multiple dma_mapping_ops (X86, POWER, and SPARC). dma_ops is set in platform_dma_init. We also set it by hand where machvec_init is callev via subsys_initcall. - IA64_DIG_VTD uses vtd_dma_ops. - IA64_HP_ZX1 uses sba_dma_ops. - IA64_HP_ZX1_SWIOTLB uses hwsw_dma_ops. - IA64_SGI_SN2 uses sn_dma_ops. - The rest use swiotlb_dma_ops.

2008-07-26dma-mapping: add the device argument to dma_mapping_error()FUJITA Tomonori1-1/+1
Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER architecture does: This enables us to cleanly fix the Calgary IOMMU issue that some devices are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423). I think that per-device dma_mapping_ops support would be also helpful for KVM people to support PCI passthrough but Andi thinks that this makes it difficult to support the PCI passthrough (see the above thread). So I CC'ed this to KVM camp. Comments are appreciated. A pointer to dma_mapping_ops to struct dev_archdata is added. If the pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's NULL, the system-wide dma_ops pointer is used as before. If it's useful for KVM people, I plan to implement a mechanism to register a hook called when a new pci (or dma capable) device is created (it works with hot plugging). It enables IOMMUs to set up an appropriate dma_mapping_ops per device. The major obstacle is that dma_mapping_error doesn't take a pointer to the device unlike other DMA operations. So x86 can't have dma_mapping_ops per device. Note all the POWER IOMMUs use the same dma_mapping_error function so this is not a problem for POWER but x86 IOMMUs use different dma_mapping_error functions. The first patch adds the device argument to dma_mapping_error. The patch is trivial but large since it touches lots of drivers and dma-mapping.h in all the architecture. This patch: dma_mapping_error() doesn't take a pointer to the device unlike other DMA operations. So we can't have dma_mapping_ops per device. Note that POWER already has dma_mapping_ops per device but all the POWER IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device argument.

2006-12-01Altix: Add initial ACPI IO supportJohn Keller2-34/+1
First phase in introducing ACPI support to SN. In this phase, when running with an ACPI capable PROM, the DSDT will define the root busses and all SN nodes (SGIHUB, SGITIO). An ACPI bus driver will be registered for the node devices, with the acpi_pci_root_driver being used for the root busses. An ACPI vendor descriptor is now used to pass platform specific information for both nodes and busses, eliminating the need for the current SAL calls. Also, with ACPI support, SN fixup code is no longer needed to initiate the PCI bus scans, as the acpi_pci_root_driver does that. However, to maintain backward compatibility with non-ACPI capable PROMs, none of the current 'fixup' code can been deleted, though much restructuring has been done. For example, the bulk of the code in io_common.c is relocated code that is now common regardless of what PROM is running, while io_acpi_init.c and io_init.c contain routines specific to an ACPI or non ACPI capable PROM respectively. A new pci bus fixup platform vector has been created to provide a hook for invoking platform specific bus fixup from pcibios_fixup_bus(). The size of io_space[] has been increased to support systems with large IO configurations. Signed-off-by: John Keller <jpk@sgi.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2-4/+2
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.
