In discrete cards, the graphics driver shouldn't proceed with the probe or resume unless PCODE indicated everything is done, including memory training and gt bring up. For this reason, the driver probe and resume paths needs to be blocked until PCODE indicates it is done. Also, it needs to aborted if the notification never arrives. In general, the few miliseconds would be enough and the regular PCODE recommendation for the timeout was 10 seconds. However there are some rare cases where this initialization can take up to 1 minute. So, PCODE has increased the recommendation to 3 minutes so we don't fully block the device utilization when something just got delayed for whatever reason. To be on the safest side, let's accept this recommendation, since on the regular case it won't delay or block the driver initialization and resume flows Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Badal Nilawar <badal.nilawar@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210727173338.901264-1-badal.nilawar@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.
