:doc: driver specific ioctls
+Recommended IOCTL Return Values
+-------------------------------
+
+In theory a driver's IOCTL callback is only allowed to return very few error
+codes. In practice it's good to abuse a few more. This section documents common
+practice within the DRM subsystem:
+
+ENOENT:
+ Strictly this should only be used when a file doesn't exist e.g. when
+ calling the open() syscall. We reuse that to signal any kind of object
+ lookup failure, e.g. for unknown GEM buffer object handles, unknown KMS
+ object handles and similar cases.
+
+ENOSPC:
+ Some drivers use this to differentiate "out of kernel memory" from "out
+ of VRAM". Sometimes also applies to other limited gpu resources used for
+ rendering (e.g. when you have a special limited compression buffer).
+ Sometimes resource allocation/reservation issues in command submission
+ IOCTLs are also signalled through EDEADLK.
+
+ Simply running out of kernel/system memory is signalled through ENOMEM.
+
+EPERM/EACCESS:
+ Returned for an operation that is valid, but needs more privileges.
+ E.g. root-only or much more common, DRM master-only operations return
+ this when when called by unpriviledged clients. There's no clear
+ difference between EACCESS and EPERM.
+
+ENODEV:
+ Feature (like PRIME, modesetting, GEM) is not supported by the driver.
+
+ENXIO:
+ Remote failure, either a hardware transaction (like i2c), but also used
+ when the exporting driver of a shared dma-buf or fence doesn't support a
+ feature needed.
+
+EINTR:
+ DRM drivers assume that userspace restarts all IOCTLs. Any DRM IOCTL can
+ return EINTR and in such a case should be restarted with the IOCTL
+ parameters left unchanged.
+
+EIO:
+ The GPU died and couldn't be resurrected through a reset. Modesetting
+ hardware failures are signalled through the "link status" connector
+ property.
+
+EINVAL:
+ Catch-all for anything that is an invalid argument combination which
+ cannot work.
+
+IOCTL also use other error codes like ETIME, EFAULT, EBUSY, ENOTTY but their
+usage is in line with the common meanings. The above list tries to just document
+DRM specific patterns. Note that ENOTTY has the slightly unintuitive meaning of
+"this IOCTL does not exist", and is used exactly as such in DRM.

+
+For drivers which could have multiple instances, it is necessary to
+differentiate between which is which in the logs. Since DRM_INFO/WARN/ERROR
+don't do this, drivers used dev_info/warn/err to make this differentiation. We
+now have DRM_DEV_* variants of the drm print macros, so we can start to convert
+those drivers back to using drm-formwatted specific log messages.
+
+Contact: Sean Paul, Maintainer of the driver you plan to convert

+ *
+ * The Faraday TV Encoder TVE200 is also known as the Gemini TV Interface
+ * Controller (TVC) and is found in the Gemini Chipset from Storlink
+ * Semiconductor (later Storm Semiconductor, later Cortina Systems)
+ * but also in the Grain Media GM8180 chipset. On the Gemini the module
+ * is connected to 8 data lines and a single clock line, comprising an
+ * 8-bit BT.656 interface.
+ *
+ * This is a very basic YUV display driver. The datasheet specifies that
+ * it supports the ITU BT.656 standard. It requires a 27 MHz clock which is
+ * the hallmark of any TV encoder supporting both PAL and NTSC.
+ *
+ * This driver exposes a standard KMS interface for this TV encoder.
