So we can have portable formatting of uint32_t types. However there is a catch. Different compilers can use legally subtly different types though so we need to probe the compiler defined intdef.h first. Signed-off-by:

This patch reverts the stty parts of 8727c886 "runtime: better handling of QEMU aborts", as we can more robustly fix the same issue by simply redirecting /dev/null into qemu's stdin. The obvious side effect of this is that serial input will no longer be wired up to the tty (or any other input file descriptor), but unit tests do not, and should not, be reading from the serial port anyway.

First of all, vtd_setup_msi() is provided. It setup IRTE entries, meanwhile, setup PCI device MSI vectors corresponding to VT-d spec. Meanwhile, IR MSI test is added to intel IOMMU unit test. The basic IR test is carried out by a edu INTR raise request. When write to the intr raise register, interrupt will be generated. Type of interrupt will depend on the setup (either INTx or MSI).

pci_cap_walk() is provided to allow walk through all the capability bits for a specific PCI device. If a cap handler is provided, it'll be triggered if the cap is detected along the cap walk. MSI cap handler is the first one supported. We can add more cap handler in the future. Meanwhile, pci_setup_msi() API is provided to support basic 32/64 bit address MSI setup. Reviewed-by:

QEMU edu device is a pci device that is originally written for educational purpose, however it also suits for IOMMU unit test. Adding helpers for this specific device to implement the device logic. The device supports lots of functions, here only DMA operation is supported. The spec of the device can be found at: https://github.com/qemu/qemu/blob/master/docs/specs/edu.txt Reviewed-by:

To extend current PCI framework, we need a per-device struct to store device specific information. Time to have a pci_dev struct. Most of the current PCI APIs are converted to use this pci_dev object as the first argument. Currently it only contains one field "bdf", which is the bdf of current device. For a few APIs like pci_config_*() ops or pci_find_dev(), I kept the old interface (use PCI BDF value rather than "struct pci_dev") since they can be used in a open context that without any specific PCI device.

Adding fundamental init test for Intel IOMMU. This includes basic initialization of Intel IOMMU device, like DMAR (DMA Remapping), IR (Interrupt Remapping), QI (Queue Invalidation), etc. Further tests can use vtd_init() to initialize Intel IOMMU environment. x86/unittests is updated to add this test.

Currently test.log gets output of the form test1-command-line test1-output SUMMARY: test2-command-line test2-output SUMMARY: test3-command-line ... Having a blank line before SUMMARY, and not after, it makes it tough to group lines by eye. Change it to test1-command-line test1-output SUMMARY: test2-command-line test2-output SUMMARY: test3-command-line ... The empty line is moved from report_summary to runtime in order to remove it altogether when running tests individually or as a standalone. Signed-off-by:

cpu_init must be called before mem_init because cpu_init determines the cache-line sizes. Currently io_init has no dependency on mem_init, but io_init should be allowed to use heap allocation, and someday it may, so we proactively comment it.

While reading code I noticed we need to call thread_info_init before mem_init to be correct. In practice it hasn't mattered because cpu0 is calling mem_init, and it's cpu index is 0, which is what a fresh first boot would have it be anyway. With reset tests (coming soon) combined with mmu tests (hopefully coming someday) it could be problematic though, so let's fix it. Additionally comment the order to make sure we maintain it. The io_init dependency on mem_init is because io_init calls init functions that make use of heap allocation. Signed-off-by: -

Instead of using cpu0 and irq=0 for the IPI test, use something a bit more interesting. To make sure we can still run the test with the minimal number of cpus (2), we need to use sender=1. As the irq in the test (an SGI) can only be 0 to 15 and there's really no difference, then use irq=1. sender=1 is a bit limited for the long term, as we may want to test IPIs across host sockets with pinned vcpus. But we can improve on this later, possibly with the introduction of a command line parameter. Reviewed-by:
