Apparently kernel patch "x86/cpa: Use pte_attrs instead of pte_flags on CPA/set_p.._wb/wc operations" (in out repo) doesn't fully solve the problem and sometimes qubes-gui agent crashes with message like "qubes-gui:664 map pfn expected mapping type write-back for [mem 0x00093000-0x00093fff], got uncached-minus". Because PAT we really need only in dom0 (lack of it dramatically decrease performance of some graphics drivers), we can simply disable it in VM - as it is currently done in upstream kernel. |
