Hi Daniel,
1.On Harris Beach, we always see this report as below even we set
different TOLUD size, such as1GB, 1.5GB, 2GB and 3GB :
[drm] Memory usable by graphics device = 2048M
2. Based on the implementation below, it shouldn't matter
with TOLUD size.
DRM_INFO("Memory Usable by graphics device = %dM\n",
dev_priv->mm.gtt->gtt_total_entries >> 8);
Please confirm if this is the case:
If RAM is 4GB, it will report 2048M as the usable memory by graphics
device.
This is the max size that graphics could use, and it shouldn't change
based on TOLUD size.
Yeah. But the real question is what do you need this for exactly? Also,
cc'ing relevant internal mailing lists.
