To open a cec device applications call :c:func:`open()` with the

-
- This documents the proposed CEC API. This API is not yet finalized
- and is currently only available as a staging kernel module.
-
HDMI connectors provide a single pin for use by the Consumer Electronics
Control protocol. This protocol allows different devices connected by an
HDMI cable to communicate. The protocol for CEC version 1.4 is defined
Drivers that support CEC will create a CEC device node (/dev/cecX) to
give userspace access to the CEC adapter. The
:ref:`CEC_ADAP_G_CAPS` ioctl will tell userspace what it is allowed to do.
+
+In order to check the support and test it, it is suggested to download
+the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ package. It
+provides three tools to handle CEC:
+
+- cec-ctl: the Swiss army knife of CEC. Allows you to configure, transmit
+ and monitor CEC messages.
+
+- cec-compliance: does a CEC compliance test of a remote CEC device to
+ determine how compliant the CEC implementation is.
+
+- cec-follower: emulates a CEC follower.
Description
===========
-.. note::
-
- This documents the proposed CEC API. This API is not yet finalized
- and is currently only available as a staging kernel module.
-
All cec devices must support :ref:`ioctl CEC_ADAP_G_CAPS <CEC_ADAP_G_CAPS>`. To query
device information, applications call the ioctl with a pointer to a
struct :c:type:`cec_caps`. The driver fills the structure and
Description
===========
-.. note::
-
- This documents the proposed CEC API. This API is not yet finalized
- and is currently only available as a staging kernel module.
-
To query the current CEC logical addresses, applications call
:ref:`ioctl CEC_ADAP_G_LOG_ADDRS <CEC_ADAP_G_LOG_ADDRS>` with a pointer to a
struct :c:type:`cec_log_addrs` where the driver stores the logical addresses.
Description
===========

-
- This documents the proposed CEC API. This API is not yet finalized

-
CEC devices can send asynchronous events. These can be retrieved by
calling :c:func:`CEC_DQEVENT`. If the file descriptor is in
non-blocking mode and no event is pending, then it will return -1 and

- This documents the proposed CEC API. This API is not yet finalized
- and is currently only available as a staging kernel module.
-
By default any filehandle can use :ref:`CEC_TRANSMIT`, but in order to prevent
applications from stepping on each others toes it must be possible to
obtain exclusive access to the CEC adapter. This ioctl sets the
Description

-.. note::
-
- This documents the proposed CEC API. This API is not yet finalized

To receive a CEC message the application has to fill in the
``timeout`` field of struct :c:type:`cec_msg` and pass it to
:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
The default suspend mode (ie. the one to be used without writing anything into
/sys/power/mem_sleep) is either "deep" (if Suspend-To-RAM is supported) or
"s2idle", but it can be overridden by the value of the "mem_sleep_default"
-parameter in the kernel command line. On some ACPI-based systems, depending on
-the information in the FADT, the default may be "s2idle" even if Suspend-To-RAM
-is supported.

+ *
+ * This function is called when user wants to reset a virtual GPU through

+ *
+ * vGPU Device Model Level Reset (DMLR) simulates the PCI level reset to reset
+ * the whole vGPU to default state as when it is created. This vGPU function
+ * is required both for functionary and security concerns.The ultimate goal
+ * of vGPU FLR is that reuse a vGPU instance by virtual machines. When we
+ * assign a vGPU to a virtual machine we must isse such reset first.
+ *
+ * Full GT Reset and Per-Engine GT Reset are soft reset flow for GPU engines
+ * (Render, Blitter, Video, Video Enhancement). It is defined by GPU Spec.
+ * Unlike the FLR, GT reset only reset particular resource of a vGPU per
+ * the reset request. Guest driver can issue a GT reset by programming the
+ * virtual GDRST register to reset specific virtual GPU engine or all
+ * engines.
+ *
+ * The parameter dev_level is to identify if we will do DMLR or GT reset.
+ * The parameter engine_mask is to specific the engines that need to be
+ * resetted. If value ALL_ENGINES is given for engine_mask, it means
+ * the caller requests a full GT reset that we will reset all virtual
+ * GPU engines. For FLR, engine_mask is ignored.
