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.

Many (especially embedded drivers) want to delay fbdev setup until there's a
