Hey Rusty, This is the way I did the split; patches 1..7 are preparation for multiple ports. Patch 8 adds multiport support. It's the big one since we have to put the header in and retain support for multiple consoles and console resizing. Patch 9 adds port hotplug Patch 10 adds sysfs entries and 12 adds debugfs. Patches 13, 14 and 15 add throttling, caching and unplug features.

Hey Rusty, In this version: - Assume only one inbuf; no input buffering for ports - Remove the START/END delimiters for outgoing buffers - Remove the header that was sent along with each buffer - Remove unused buffers in the vqs at port remove time - Send a guest port open message to the host when a console port is attached - Remove cached buffers when ports are closed / disconnected - Send

Hello, This series reworks the ABI to allow port discovery (only) via the control queue and enable multiport again. In addition, it adds support for non-blocking write() support, which means no spinning. This works fine with the recent patches that are on qemu-devel. Also included is removal of hvc_remove() as removing one such console port causes other console ports (registered with hvc) to

Hey Rusty, This is a respin of my patches on top of the series you posted. I've taken the liberty to modify your patches for style consistency and comments where needed, keeping the authorship info intact. I've had to update a few of your patches for functional changes, I've changed the authorship info on those patches. The (only) major functional change is to have a list for ports

This patch set if my first attempt to make virtio_console usable on s390. To do so, I had to change hvc_console, because s390 has no request_irq and no free_irq. I want to get feedback from the main users of hvc_console before I proceed. The basic idea of this patch set is to remove the calls to request_irq and free_irq and replace them with backend specific callbacks. Please see the
