The previous implementation of eGalax protocol was not satisfying as we had to manually set x/y ranges as they were corrupted after reading the report descriptor. Indeed, the report descriptor provided a stylus input interface which override the correct values. This patch omits this input, thus leaving the correct value untouched, and the MT_QUIRK_EGALAX_XYZ_FIXUP not required anymore.

This patch, based on virtio PCI driver, adds support for memory mapped (platform) virtio device. This should allow environments like qemu to use virtio-based block & network devices even on platforms without PCI support. One can define and register a platform device which resources will describe memory mapped control registers and "mailbox" interrupt. Such device can be also instantiated using the Device Tree node with compatible property equal "virtio,mmio".

For the MSI but non-per_vq_vector case, the config/change vq also gets added to the list of vqs that need to process the MSI interrupt. This is not needed as config has it's own handler (vp_config_changed). In any case, vring_interrupt() finds nothing needs to be done on this vq.

On s390 I have seen some random "Warning: unable to open an initial console" boot failure. Turns out that tty_open fails, because the hvc_alloc was not yet done. In former times this could not happen, since the probe function automatically called hvc_alloc. With newer versions (multiport) some host<->guest interaction is required before hvc_alloc is called. This might be too late, especially if an initramfs is involved. Lets use a completion if we have multiport and an early console.

This commit adds port-specific stats for the number of bytes received, sent and discarded. They're exposed via the debugfs interface. This data can be used to check for data loss bugs (or disprove such claims). It can also be used for accounting, if there's such a need. The stats remain valid throughout the lifetime of the port. Unplugging a port will reset the stats. The numbers are not reset across port opens/closes. Signed-off-by: NAmit Shah <amit.shah@redhat.com> Signed-off-by: NRusty Russell <rusty@rustcorp.com.au>

Instead of pulling in a buffer from the vq each time it's called, get_inbuf() now checks if the current active buffer, in port->inbuf is valid. If it is, just returns a pointer to it.

We don't allow port name changes dynamically for a port. So any requests by the host to change the name are ignored. Before this patch, if the hypervisor sent a port name while we had one set already, we would leak memory equivalent to the size of the old name. This scenario wasn't expected so far, but with the suspend-resume support, we'll send the VIRTIO_CONSOLE_PORT_READY message after restore, which can get us into this situation.
