For shared, and read-only private mappings of graphics memory, use VM_PFNMAP instead of VM_MIXEDMAP. This means less accounting overhead when inserting and removing page-table entries. TTM doesn't do this by default, since there was a performance problem with book-keeping of write-combined mappings. Since vmwgfx solely uses cached mappings, that's not a problem and now that the TTM vm has largely been turned into helpers, we can use VM_PFNMAP on a per-driver basis Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Roland Scheidegger <sroland@vmware.com> |
