We cannot recover a VM if a rebind worker hits an error, ban the VM if happens to ensure we do not attempt to place this VM on the hardware again. A follow up will inform the user if this happens. v2: Return -ECANCELED in exec VM closed or banned, check for closed or banned within VM lock. v3: Fix lockdep splat by looking engine outside of vm->lock v4: Fix error path when engine lookup fails v5: Add debug message in rebind worker on error, update comments wrt locking, add xe_vm_close helper Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
