Subject: [PATCH v2 0/3] drm/xe: More fb pinning optimizations.
Date: Mon, 22 Apr 2024 15:44:57 +0200 [thread overview]
Message-ID: <20240422134500.219271-1-maarten.lankhorst@linux.intel.com> (raw)
This reduces the latency of pinning framebuffers by
re-using the previous mapping, if available.
Additionally, DPT is preallocated when creating the FB, instead
of performing a bo allocation on every pin.
Changes since v1:
- Drop the patch to prevent overwriting GGTT, to see if this fixes the test results.
It's not needed for optimizing FB pinning.
