Subject: [Intel-gfx] [PATCH 0/3] Replace VT-d workaround with guard pages
Date: Thu, 2 Dec 2021 14:01:22 +0530 [thread overview]
Message-ID: <20211202083125.3999668-1-tejaskumarx.surendrakumar.upadhyay@intel.com> (raw)
Replace filling the GGTT entirely with scratch pages to avoid invalid
accesses from VT-d overfetch of scanout by only surrounding scanout vma
with guard pages. This eliminates the 100+ms delay in resume where we
have to repopulate the GGTT with scratch.
This should also help in avoiding slow suspend/resume on GEN11/12
platforms. Which will also resolve issues with following reported
errors : "slow framebuffer consoles issue impacts Linux S3"
