Hello, This is a new iteration of the patches that implement virtio-serial. Changes include: * Adding support for port hot-add * Creating ports at specific ids that can be bound to specific apps / usage * Cleanups This code still doesn't get rid of the support for assigning names to ports but it just has to be ripped out. Comments welcome. Thanks, Amit.

The following series applies to net-next. The following series changes the low memory paths in virtio_net to not disable NAPI while waiting in the allocator in the slow path. It attempts to rectify some performance problems we've seen where the network performance drops significantly when memory is low. The working theory is that the disabling of NAPI while allocations are occuring in the

Some notebook systems provide the EDID for the internal panel via the _DDC method in ACPI, instead of or in addition to providing the EDID via DDC on LVDS/eDP. Add a DRM helper to search for an ACP _DDC method under the ACPI namespace for each VGA/3D controller, and return the first EDID successfully retrieved via _DDC. Update the i915, nouveau, and radeon DRM-KMS drivers to fall back to

Hello all, This are the latest version of the patches. Lots of things have changed since the last submission. A few of which I remember: - VNC copy / paste works* (* conditions apply) - client vnc copies get propagated to guest port 3 (/dev/vmch3) - guest writes to port 3 (/dev/vmch3) go straight to client's clipboard - sysfs hooks to autodiscover ports - support for 64 ports in this
