[IA64] Add Variable Page Size and IA64 Support in Intel IOMMU

2008-10-17T19:14:13Z

The patch contains Intel IOMMU IA64 specific code. It defines new machvec dig_vtd, hooks for IOMMU, DMAR table detection, cache line flush function, etc. For a generic kernel with CONFIG_DMAR=y, if Intel IOMMU is detected, dig_vtd is used for machinve vector. Otherwise, kernel falls back to dig machine vector. Kernel parameter "machvec=dig" or "intel_iommu=off" can be used to force kernel to boot dig machine vector.

ia64/pv_ops: paravirtualized instruction checker.

2008-10-17T17:12:54Z

This patch implements a checker to detect instructions which should be paravirtualized instead of direct writing raw instruction. This patch does rough check so that it doesn't fully cover all cases, but it can detects most cases of paravirtualization breakage of hand written assembly codes.

[IA64] pvops: paravirtualize NR_IRQS

2008-05-27T22:09:30Z

Make NR_IRQ overridable by each pv instances. Pv instance may need each own number of irqs so that NR_IRQS should be the maximum number of nr_irqs each pv instances need. Cc: Jes Sorensen Signed-off-by: Isaku Yamahata Signed-off-by: Tony Luck

[IA64] pvops: paravirtualize entry.S

2008-05-27T22:08:01Z

paravirtualize ia64_swtich_to, ia64_leave_syscall and ia64_leave_kernel. They include sensitive or performance critical privileged instructions so that they need paravirtualization. To paravirtualize them by single source and multi compile they are converted into indirect jump. And define each pv instances.

[IA64] pvops: preparation for paravirtulization of hand written assembly code.

2008-05-27T21:46:28Z

Preparation for paravirtualization of hand written assembly code. They are paravirtualized by single source code and compiled multi times. To tell those files for target (including native), add one defines. Cc: "Dong, Eddie" Cc: Keith Owens Cc: tgingold@free.fr Signed-off-by: Isaku Yamahata Signed-off-by: Tony Luck

Generic semaphore implementation

2008-04-17T14:42:34Z

Semaphores are no longer performance-critical, so a generic C implementation is better for maintainability, debuggability and extensibility. Thanks to Peter Zijlstra for fixing the lockdep warning. Thanks to Harvey Harrison for pointing out that the unlikely() was unnecessary. Signed-off-by: Matthew Wilcox Acked-by: Ingo Molnar

[IA64] CONFIG_KEXEC/CONFIG_CRASH_DUMP permutations

2006-12-12T18:11:00Z

Actually, on reflection I think that there is a good case for keeping the options separate. I am thinking particularly of people who want a very small crashdump kernel and thus don't want to compile in kexec. The patch below should fix things up so that all valid combinations of KEXEC, CRASH_DUMP and VMCORE compile cleanly - VMCORE depends on CRASH_DUMP which is why I said valid combinations. In a nutshell it just untangles unrelated code and switches around a few defines. Please note that it creats a new file, arch/ia64/kernel/crash_dump.c This is in keeping with the i386 implementation.
