Subject: [Intel-xe] [PATCH v4 0/7] Try to handle TLB invalidations from CT fast-path
Date: Wed,  5 Jul 2023 17:06:03 +0100	[thread overview]
Message-ID: <20230705160602.237213-9-matthew.auld@intel.com> (raw)

In various test cases and workloads that put the system under a heavy load, we
can sometimes see errors with missed TLB invalidations. If we handle the TLB
completions directly from IRQ we can see a big improvement.

v4:
  - Various tweaks. Big thing is to make sure we grab the fast_lock for the g2h
    reservation when doing the CT send, which closes one big race with the CT
    fast-path.
