This module option can override that for each instance. Values are:
- 0: use alternating single and multi-planar devices.
1: this is a single-planar instance.
2: this is a multi-planar instance.
0 otherwise.
The driver has to be configured to support the multiplanar formats. By default
-the first driver instance is single-planar, the second is multi-planar, and it
-keeps alternating. This can be changed by setting the multiplanar module option,
-see section 1 for more details on that option.
+the driver instances are single-planar. This can be changed by setting the
+multiplanar module option, see section 1 for more details on that option.
If the driver instance is using the multiplanar formats/API, then the first
single planar format (YUYV) and the multiplanar NV16M and NV61M formats the
to see the blended framebuffer overlay that's being written to by the second
instance. This setup would require the following commands:
- $ sudo modprobe vivid n_devs=2 node_types=0x10101,0x1 multiplanar=1,1
+ $ sudo modprobe vivid n_devs=2 node_types=0x10101,0x1
$ v4l2-ctl -d1 --find-fb
/dev/fb1 is the framebuffer associated with base address 0x12800000
$ sudo v4l2-ctl -d2 --set-fbuf fb=1

+ * This is a very bad interface and I'm to blame for it :-(
+ *
+ * So we can't just apply a 32-bit swap to what comes from OPAL,
+ * because user space expects the *bytes* to be in their proper
+ * respective positions (ie, LPC position).
+ *
+ * So what we really want to do here is to shift data right
+ * appropriately on a LE kernel.
+ *
+ * IE. If the LPC transaction has bytes B0, B1, B2 and B3 in that
+ * order, we have in memory written to by OPAL at the "data"
+ * pointer:
+ *
+ * Bytes: OPAL "data" LE "data"
+ * 32-bit: B0 B1 B2 B3 B0B1B2B3 B3B2B1B0
+ * 16-bit: B0 B1 0000B0B1 B1B00000
+ * 8-bit: B0 000000B0 B0000000
+ *
+ * So a BE kernel will have the leftmost of the above in the MSB
+ * and rightmost in the LSB and can just then "cast" the u32 "data"
+ * down to the appropriate quantity and write it.
+ *
+ * However, an LE kernel can't. It doesn't need to swap because a
+ * load from data followed by a store to user are going to preserve
+ * the byte ordering which is the wire byte order which is what the
+ * user wants, but in order to "crop" to the right size, we need to

- don't want to ever access the information to not have the code,

+ This option controls if the device coredump mechanism is available or
+ not; if disabled, the mechanism will be omitted even if drivers that
+ can use it are enabled.
+ Say 'N' for more sensitive systems or systems that don't want
