Now that we can pass our own workqueue to drm_sched_init(), we can use an ordered workqueue on for both the scheduler timeout tdr and our own reset work (which we use when the reset is not caused by a fault/timeout on a specific job, like when we have AS_ACTIVE bit stuck). This guarantees that the timeout handlers and reset handler can't run concurrently which drastically simplifies the locking. v5: * Don't call cancel_delayed_timeout() in the reset path (those works are canceled in drm_sched_stop()) v4: * Actually pass the reset workqueue to drm_sched_init() * Don't call cancel_work_sync() in panfrost_reset(). It will deadlock since it might be called from the reset work, which is executing and cancel_work_sync() will wait for the handler to return. Checking the reset pending status should avoid spurious resets v3: * New patch Suggested-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210630062751.2832545-10-boris.brezillon@collabora.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.
