Bluetooth: allocate static minor for vhci

2014-02-18T17:49:04Z

Commit bfacbb9 (Bluetooth: Use devname:vhci module alias for virtual HCI driver) added the module alias to hci_vhci module so it's possible to create the /dev/vhci node. However creating an alias without specifying the minor doesn't allow us to create the node ahead, triggerring module auto-load when it's first accessed. Starting with depmod from kmod 16 we started to warn if there's a devname alias without specifying the major and minor. Let's do the same done for uhid, kvm, fuse and others, specifying a fixed minor. In systems with systemd as the init the following will happen: on early boot systemd will call "kmod static-nodes" to read /lib/modules/$(uname -r)/modules.devname and then create the nodes. When first accessed these "dead" nodes will trigger the module loading. Signed-off-by: Lucas De Marchi Acked-by: Greg Kroah-Hartman Signed-off-by: Marcel Holtmann

misc: Reserve minor for VFIO

2013-12-19T17:17:11Z

VFIO currently allocates it's own dynamic chardev range, reserving the first minor for the control part of the interface (/dev/vfio/vfio) and the remainder for VFIO groups (/dev/vfio/$GROUP). This works, but it doesn't support auto loading. For instance when libvirt checks for VFIO support it looks for /dev/vfio/vfio, which currently doesn't exist unless the vfio module is loaded. By converting the control device to a misc driver and reserving a static minor, we can enable auto loading. Reserving the minor is a prerequist to that conversion. Minor 196 is unused by anything currently in the kernel. Suggested-by: Paolo Bonzini Signed-off-by: Alex Williamson Acked-by: Greg Kroah-Hartman

cuse: add fix minor number to /dev/cuse

2013-10-01T14:44:54Z

This allows udev (or more recently systemd-tmpfiles) to create /dev/cuse on boot, in the same way as /dev/fuse is currently created, and the corresponding module to be loaded on first access. The corresponding functionalty was introduced for fuse in commit 578454f. Signed-off-by: Tom Gundersen Cc: Kay Sievers Signed-off-by: Miklos Szeredi

HID: uhid: allocate static minor

2013-09-26T09:03:29Z

udev has this nice feature of creating "dead" /dev/ device-nodes if it finds a devnode: modalias. Once the node is accessed, the kernel automatically loads the module that provides the node. However, this requires udev to know the major:minor code to use for the node. This feature was introduced by: commit 578454ff7eab61d13a26b568f99a89a2c9edc881 Author: Kay Sievers Date: Thu May 20 18:07:20 2010 +0200 driver core: add devname module aliases to allow module on-demand auto-loading However, uhid uses dynamic minor numbers so this doesn't actually work. We need to load uhid to know which minor it's going to use. Hence, allocate a static minor (just like uinput does) and we're good to go.

xen/mce: Add mcelog support for Xen platform

2012-07-19T19:51:36Z

When MCA error occurs, it would be handled by Xen hypervisor first, and then the error information would be sent to initial domain for logging. This patch gets error information from Xen hypervisor and convert Xen format error into Linux format mcelog. This logic is basically self-contained, not touching other kernel components. By using tools like mcelog tool users could read specific error information, like what they did under native Linux.
