similar to: [PATCH 6/9] virtio_mmio: Cast &resources[1].start to ‘unsigned int *’ to rid compiler warning

From: Bjorn Helgaas <bhelgaas at google.com> The "virtio_mmio.device=" command line argument allows a user to specify the size, address, and IRQ of a virtio device. Previously the only requirement for the IRQ was that it be an unsigned integer. Zero is an unsigned integer but an invalid IRQ number, and after a85a6c86c25be ("driver core: platform: Clarify that IRQ 0 is

This patch adds an option to instantiate guest virtio-mmio devices basing on a kernel command line (or module) parameter, for example: virtio_mmio.devices=0x100 at 0x100b0000:48 Signed-off-by: Pawel Moll <pawel.moll at arm.com> --- Hi Rusty, As the param changes are in now, could you queue this long-time-forgotten patch for 3.5? Cheers! Pawel PS. Congratulations once again and see

virtio_mmio currently lacks generation support which makes multi-byte field access racy. Fix by getting the value at offset 0xfc for version 2 devices. Nothing we can do for version 1, so return generation id 0. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> --- Pawel, you mentioned you have a working virtio 1.0 hypervisor, can you pls confirm this works correctly?

Added the match table and pointers for ACPI probing to the driver. This uses the same identifier for virt devices as being used for qemu ARM64 ACPI support. http://git.linaro.org/people/shannon.zhao/qemu.git/commit/d0bf1955a3ecbab4b51d46f8c5dda02b7e14a17e Signed-off-by: Graeme Gregory <graeme.gregory at linaro.org> --- drivers/virtio/virtio_mmio.c | 10 ++++++++++ 1 file changed, 10
