In the following patch, we will process the CSB events under the timeline.lock and not serialised by the tasklet. This also means that we will need to protect access to common variables such as execlists->csb_head with the timeline.lock during reset. v2: Move sync_irq to avoid deadlocks between taking timeline.lock from our interrupt handler. v3: Kill off the synchronize_hardirq as it raises more questions than answered; now we use the timeline.lock entirely for CSB serialisation between the irq and elsewhere, we don't need to be so heavy handed with flushing v4: Treat request cancellation (wedging after failed reset) similarly Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180628201211.13837-3-chris@chris-wilson.co.uk
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
