13 The VKMS driver can be setup with the following steps:
15 To check if VKMS is loaded, run::
17   lsmod | grep vkms
19 This should list the VKMS driver. If no output is obtained, then
20 you need to enable and/or load the VKMS driver.
21 Ensure that the VKMS driver has been set as a loadable module in your
33   sudo modprobe vkms
35 On running the lsmod command now, the VKMS driver will appear listed.
38 The VKMS driver has optional features to simulate different kinds of hardware,
40 to see the module options for vkms::
42   modinfo vkms
45 can be done while loading vkms. For example, to load vkms with cursor enabled,
48   sudo modprobe vkms enable_cursor=1
52   sudo modprobe -r vkms
76   sudo ./build/tests/<name of test> --device "sys:/sys/devices/platform/vkms"

107 - VKMS already has support for vblanks simulated via hrtimers, which can be
108   tested with kms_flip test; in some way, we can say that VKMS already mimics
112   hardware. It would be useful to support Virtual Hardware behavior in VKMS
132 all relevant igt testcases work on vkms. They are good options for internship
138 We want to be able to reconfigure vkms instance without having to reload the
150 The currently proposed solution is to expose vkms configuration through
165 - As a v4l device. This is useful for debugging compositors on special vkms
