Bluetooth: Support HCI_QUIRK_EXTERNAL_CONFIG for hci_vhci driver

2014-07-04T18:10:22+00:00

This adds support for configuring the hci_vhci virtual controllers
to require a setup stage using HCI_QUIRK_EXTERNAL_CONFIG. With this
option the virtual controller will start out as unconfigured.

Bluetooth: Support HCI_QUIRK_RAW_DEVICE for hci_vhci driver

2014-07-03T15:42:58+00:00

This adds support for configuring the hci_vhci virtual controllers
as a raw-only device using HCI_QUIRK_RAW_DEVICE. This is useful for
testing the kernel internal infrastructure.

Bluetooth: allocate static minor for vhci

2014-02-18T17:49:04+00:00

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.

Bluetooth: Add support for vectored writes to virtual HCI driver

2013-12-29T19:25:52+00:00

The Bluetooth virtual HCI driver is using a misc character device to
allow emulation of HCI devices from userspace. This change enables the
support for vectored writes. Previously this was failing with EINVAL
since no complete H:4 packet was written.

Bluetooth: Remove pointless parameter check in vhci_send_frame()

2013-10-11T15:00:38+00:00

The hdev parameter of vhci_send_frame() is always valid. If it were
not valid, then it would have crashed earlier in the call chain.

Bluetooth: Add hdev parameter to hdev->send driver callback

2013-10-11T13:28:03+00:00

Instead of masking hdev inside the skb->dev parameter, hand it
directly to the driver as a parameter to hdev->send. This makes
the driver interface more clear and simpler.

This patch fixes all drivers to accept and handle the new parameter
of hdev->send callback. Special care has been taken for bpa10x
and btusb drivers that require having skb->dev set to hdev for
the URB transmit complete handlers.

Bluetooth: Provide hdev parameter to hci_recv_frame() driver callback

2013-10-11T07:45:34+00:00

To avoid casting skb->dev into hdev, just let the drivers provide
the hdev directly when calling hci_recv_frame() function.

This patch also fixes up all drivers to provide the hdev.

Bluetooth: Add support creating virtual AMP controllers

2013-09-16T17:35:55+00:00

So far the only option to create a virtual AMP controller was by
setting a module parameter for the hci_vhci driver. This patch adds
the functionality to define inline to create either a BR/EDR or an
AMP controller.

In addition the client will be informed which HCI controller index
it got assigned. That is especially useful for automated end-to-end
testing.

To keep backwards compatibility with existing userspace, the command
for creating a controller type needs to be send right after opening
the device node. If the command is not send, it defaults back to
automatically creating a BR/EDR controller.

Bluetooth: Use devname:vhci module alias for virtual HCI driver

2013-09-16T17:35:55+00:00

To allow creating /dev/vhci device node, add the proper module alias for
this driver.
