[PATCH v2 00/15] Execlist based Engine reset and recovery

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series is to add Engine reset support (aka TDR - Timeout detection and
recovery) to i915. This is supported from Gen8 onwards and this is the
implementation with Execlist submission.

Upstream effort was originally started by Tomas Elf, now I am cotinuing it.

These patches are based on current nightly. TDR makes some changes to
wait_request path and there are some patches on the list which are
improving that path but may take some time before they get merged, these
paches need to updated accordingly if they get merged soon.

This is mainly a rebase of previous version [1].
