| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 67d02a1bbb334558e9380409a3cd426b36d4578b This should reallow binding of of-devices by name. It turned out that there are valid reasons (e.g. step by step conversion to device tree probing using auxdata) to bind of-instantiated devices to drivers by name. So revert to the original logic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several indications that make a platform device match a platform driver. For devices that are instantiated by a device tree matching by name, id table or acpi mechanisms doesn't make sense and might result in surprising effects. So limit matching to use the driver's of_match_table for these.

| * | firmware: create directory hierarchy for sysfs fw_cfg entriesGabriel Somlo2016-02-091-3/+106

While the fw_cfg device doesn't itself impose any specific naming convention, QEMU developers have traditionally used path name semantics (i.e. "etc/acpi/rsdp") to descriptively name the various fw_cfg "blobs" passed into the guest. This patch attempts, on a best effort basis, to create a directory hierarchy representing the content of fw_cfg file names, under /sys/firmware/qemu_fw_cfg/by_name. Upon successful creation of all directories representing the "dirname" portion of a fw_cfg file, a symlink will be created to represent the "basename", pointing at the appropriate /sys/firmware/qemu_fw_cfg/by_key entry. If a file name is not suitable for this procedure (e.g., if its basename or dirname components collide with an already existing dirname component or basename, respectively) the corresponding fw_cfg blob is skipped and will remain available in sysfs only by its selector key value.

Also, a "raw" attribute allows retrieval of the full binary content of each entry. The fw_cfg device can be instantiated automatically from ACPI or the Device Tree, or manually by using a kernel module (or command line) parameter, with a syntax outlined in the documentation file.

This includes - Handling the vfio type1 interface as an API rather than a specific implementation, allowing multiple type1 providers. - Capability chains, similar to PCI device capabilities, that allow extending ioctls. Extensions here include device specific regions and sparse mmap descriptions. The former is used to expose non-PCI regions for IGD, including the OpRegion (particularly the Video BIOS Table), and read only PCI config access to the host and LPC bridge as drivers often depend on identifying those devices. Sparse mmaps here are used to describe the MSIx vector table, which vfio has always protected from mmap, but never had an API to explicitly define that protection. In future vGPU support this is expected to allow the description of PCI BARs that may mix direct access and emulated access within a single region. - The ability to expose the shadow ROM as an option ROM as IGD use cases may rely on the ROM even though the physical device does not make use of a PCI option ROM BAR" * tag 'vfio-v4.6-rc1' of git://github.com/awilliam/linux-vfio: vfio/pci: return -EFAULT if copy_to_user fails vfio/pci: Expose shadow ROM as PCI option ROM vfio/pci: Intel IGD host and LCP bridge config space access vfio/pci: Intel IGD OpRegion support vfio/pci: Enable virtual register in PCI config space vfio/pci: Add infrastructure for additional device specific regions vfio: Define device specific region type capability vfio/pci: Include sparse mmap capability for MSI-X table regions vfio: Define sparse mmap capability for regions vfio: Add capability chain helpers vfio: Define capability chains vfio: If an IOMMU backend fails, keep looking vfio/pci: Fix unsigned comparison overflow

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Typically config space for a device is mapped out into capability specific handlers and unassigned space. The latter allows direct read/write access to config space. Sometimes we know about registers living in this void space and would like an easy way to virtualize them, similar to how BAR registers are managed. To do this, create one more pseudo (fake) PCI capability to be handled as purely virtual space. Reads and writes are serviced entirely from virtual config space.

Device specific code can register these regions with the new vfio_pci_register_dev_region() function. The ops structure per region currently only includes read/write access and a release function, allowing automatic cleanup when the device is closed. mmap support is only missing here because it's not needed by the first user queued for this support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vfio-pci has never allowed the user to directly mmap the MSI-X vector table, but we've always relied on implicit knowledge of the user that they cannot do this. Now that we have capability chains that we can expose in the region info ioctl and a sparse mmap capability that represents the sub-areas within the region that can be mmap'd, we can make the mmap constraints more explicit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider an IOMMU to be an API rather than an implementation, we might have multiple implementations supporting the same API, so try another if one fails. The expectation here is that we'll really only have one implementation per device type. For instance the existing type1 driver works with any PCI device where the IOMMU API is available. A vGPU vendor may have a virtual PCI device which provides DMA isolation and mapping through other mechanisms, but can re-use userspaces that make use of the type1 VFIO IOMMU API. This allows that to work. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

For instance (start + count) might overflow and wrap, getting through our validation test. Also when unwinding setup, -1 being compared as unsigned doesn't produce the intended stop condition. Fix both of these and also fix vfio_msi_set_vector_signal() to validate parameters before using the vector index, though none of the callers should pass bad indexes anymore.
