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

Hello, This patchset is still based on Linus' tree but I'll rebase when Rusty sends out the disable multiport patches. This series reworks the ABI to allow port discovery (only) via the control queue. 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

Hey Rusty, This patchset is on top of the previous one. It sends a SIGIO signal to apps that request signals for host activity. SIGIO is sent on host connect, disconnect as well as hot-unplug (which can be seen as a special case of host disconnect). Tested using several testcases in the test-virtserial repo: http://fedorapeople.org/gitweb?p=amitshah/public_git/test-virtserial.git Please apply.

Hello all, Here is a new iteration of the patch series that implements a transport for guest and host communications. I've tested for compatibility (old qemu & new kernel, new qemu & old kernel, new qemu & new kernel) and it all works fine. To maintain backward compatibility, the first port to be spawned (port at id 0) is to be a console port, to be bound to hvc. This keeps new

Hi Rusty, The main thing in these patches is the introduction of injecting SIGIO on host-side connect/disconnect events and when new data is available for ports. The first two patches fix bugs that I haven't seen, but look like the right thing to do. These have been tested extensively using the test-virtserial test suite. Please apply, Amit.
