[PATCH i-g-t v2 00/66] Test coverage for GPU debug support

[Christoph Manszewski <christoph.manszewski@intel.com>]

Hi,

In this series the eudebug kernel and validation team would like to
add test coverage for GPU debug support recently proposed as an RFC.
(https://patchwork.freedesktop.org/series/136572/)

This series adds 'xe_eudebug' and 'xe_eudebug_online' tests together
with a library that encapsulates common paths in current and future
EU debugger scenarios. It also extends the 'xe_exec_sip' test and
'gpgpu_shader' library.

The aim of the 'xe_eudebug' test is to validate the eudebug resource
tracking and event delivery mechanism. The 'xe_eudebug_online' test is
dedicated for 'online' scenarios which means scenarios that exercise
hardware exception handling and thread state manipulation.

The xe_eudebug library provides an abstraction over debugger and debuggee
processes, asynchronous event reader, and event log buffers for post-mortem
analysis.

Latest kernel code can be found here:
https://gitlab.freedesktop.org/miku/kernel/-/commits/eudebug-dev

Thank you in advance for any comments and insight.
