Hi all, The series is a draft of generic MSI driver that supports PCI and Non-PCI device which have MSI capability. If you're not interested it, sorry for the noise. The series is based on Linux-3.16-rc1. MSI was introduced in PCI Spec 2.2. Currently, kernel MSI driver codes are bonding with PCI device. Because MSI has a lot advantages in design. More and more non-PCI devices want to use

This is the first set of patches to make Nouveau work on Tegra. Those are only the obvious correctness fixes, a lot of optimization work remains to be done, but at least it's enough to get accel working and let the machine survive a piglit run. A new BO flag is introduced to allow userspace to hint the kernel about possible optimizations. Lucas Stach (6): drm/ttm: recognize ARM arch in

There is a BUG_ON() at xen/arch/x86/physdev.c:169 which appears to be dependent upon guest behavior (should close event channel before un-mapping pirq), rather than on internal hypervisor state. In 2.6.18, this likely goes unnoticed because pci_device_shutdown() only calls all the driver shutdown routines. In newer kernels, however, it also calls pci_msi_shutdown() and pci_msix_shutdown(), which
