[PATCH 00/18] GPU debug support (eudebug) v2

[Mika Kuoppala]

Hi,

This is a continuation of the first submission for GPU debug support:

https://lists.freedesktop.org/archives/intel-xe/2024-July/043605.html

The most significant changes are:
  1. Placing the code behind Kconfig switch

  2. Using rw_semaphore to allow resource discovery to run without
     individual resource locks.

The page fault handling RFC will be based on this series but will be
posted separately.

Thanks to all contributors for their feedback on v1 and to patch
authors for their fixes. I hope I haven't missed anything.

Mika
