With userspace allocated iova (next patch), we can have a race condition where userspace observes the fence completion and deletes the vma before retire_submit() gets around to unpinning the vma. To handle this, add a fenced unpin which drops the refcount but tracks the fence, and update msm_gem_vma_inuse() to check any previously unsignaled fences. v2: Fix inuse underflow (duplicate unpin) v3: Fix msm_job_run() vs submit_cleanup() race condition Signed-off-by: Rob Clark <robdclark@chromium.org> Link: https://lore.kernel.org/r/20220411215849.297838-10-robdclark@gmail.com Signed-off-by: Rob Clark <robdclark@chromium.org> |

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.
