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

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, These updated patches in the series return -EFAULT on copy_xx_user errors and also move the copy_from_user into fops_write() instead of it being in send_buf. This enables send_buf to just read from kernel buffers, making it simpler. This also allows write()s to write more to the host in one go, removingthe 4k limitation. I do limit the writes to 32k at once to not put too much

Hello all, Here is a new iteration of the patch series that implements a transport for guest and host communications. The code has been updated to reuse the virtio-console device instead of creating a new virtio-serial device. I've tested for compatibility (old qemu & new kernel, new qemu & old kernel, new qemu & new kernel) and it all works fine. There are a few items on my

The in-vq operations were protected by a lock, but the out-vq operations were not. This caused panics / errors as described in patch 2. Fix that. The first patch renames the existing cvq_lock to c_ivq_lock to match c_ivq. The second patch introduces the c_ovq_lock for the c_ovq. Please apply. I also believe this is a candidate for stable. v2: * Use spin_lock instead of spin_lock_irq.
