There is no reason to add gtt_offset to the cached head/tail pointers stream->oa_buffer.head and stream->oa_buffer.tail. This causes the code to constantly add gtt_offset and subtract gtt_offset and is error prone. It is much simpler to maintain stream->oa_buffer.head and stream->oa_buffer.tail without adding gtt_offset to them and just allow for the gtt_offset when reading/writing from/to HW registers. v2: Minor tweak to commit message due to dropping patch in previous series Signed-off-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Reviewed-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230920040211.2351279-1-ashutosh.dixit@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.
