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

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.

Hello all, I'm using gentoo, with kernel 3.17.0-p1-pf and at some point, a patch was included in this branch of the gentoo kernel that broke hdmi audio. I've checked with the latest 3.19 vanilla kernel, and I still have the same problem. I cannot output multichannel sound over hdmi. After some investigations, I've narrowed down the issue to the following lines in the file

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
