Should we do the > "mustbezero"-trick for gen < 8?
IMHO it makes more sense to have this alias on any struct that already has the "Memory Object Control State" field, even if it's not used (just like the memory object control state field is also not used). Also regarding the "mustbezero", since the documentation doesn't say it should be zero, I would do that. Not setting it in the code will already make sure it defaults to zero. > > <field name="Cut Index Enable" start="10" end="10" type="bool"/> > > <field name="Index Format" start="8" end="9" type="uint" > > prefix="INDEX"> > > <value name="BYTE" value="0"/> > > diff --git a/src/intel/genxml/gen7.xml b/src/intel/genxml/gen7.xml > > index fd70414..c98327a 100644 > > --- a/src/intel/genxml/gen7.xml > > +++ b/src/intel/genxml/gen7.xml > > @@ -1220,6 +1220,7 @@ > > <field name="3D Command Opcode" start="24" end="26" type="uint" > > default="0"/> > > <field name="3D Command Sub Opcode" start="16" end="23" type="uint" > > default="10"/> > > <field name="Memory Object Control State" start="12" end="15" > > type="MEMORY_OBJECT_CONTROL_STATE"/> > > + <field name="IndexBufferMOCS" start="12" end="15" type="uint"/> > > <field name="Cut Index Enable" start="10" end="10" type="bool"/> > > <field name="Index Format" start="8" end="9" type="uint" > > prefix="INDEX"> > > <value name="BYTE" value="0"/> > > diff --git a/src/intel/genxml/gen75.xml b/src/intel/genxml/gen75.xml > > index ac2dbc3..11f1462 100644 > > --- a/src/intel/genxml/gen75.xml > > +++ b/src/intel/genxml/gen75.xml > > @@ -1506,6 +1506,7 @@ > > <field name="3D Command Opcode" start="24" end="26" type="uint" > > default="0"/> > > <field name="3D Command Sub Opcode" start="16" end="23" type="uint" > > default="10"/> > > <field name="Memory Object Control State" start="12" end="15" > > type="MEMORY_OBJECT_CONTROL_STATE"/> > > + <field name="IndexBufferMOCS" start="12" end="15" type="uint"/> > > <field name="Index Format" start="8" end="9" type="uint" > > prefix="INDEX"> > > <value name="BYTE" value="0"/> > > <value name="WORD" value="1"/> > > diff --git a/src/intel/genxml/gen8.xml b/src/intel/genxml/gen8.xml > > index 1392466..541a788 100644 > > --- a/src/intel/genxml/gen8.xml > > +++ b/src/intel/genxml/gen8.xml > > @@ -1583,6 +1583,7 @@ > > <value name="DWORD" value="2"/> > > </field> > > <field name="Memory Object Control State" start="32" end="38" > > type="MEMORY_OBJECT_CONTROL_STATE"/> > > + <field name="IndexBufferMOCS" start="32" end="38" type="uint"/> > > <field name="Buffer Starting Address" start="64" end="127" > > type="address"/> > > <field name="Buffer Size" start="128" end="159" type="uint"/> > > </instruction> > > diff --git a/src/intel/genxml/gen9.xml b/src/intel/genxml/gen9.xml > > index 445a366..a2c2020 100644 > > --- a/src/intel/genxml/gen9.xml > > +++ b/src/intel/genxml/gen9.xml > > @@ -1696,6 +1696,7 @@ > > <value name="DWORD" value="2"/> > > </field> > > <field name="Memory Object Control State" start="32" end="38" > > type="MEMORY_OBJECT_CONTROL_STATE"/> > > + <field name="IndexBufferMOCS" start="32" end="38" type="uint"/> > > <field name="Buffer Starting Address" start="64" end="127" > > type="address"/> > > <field name="Buffer Size" start="128" end="159" type="uint"/> > > </instruction> > > -- > > 2.9.3 > > > > _______________________________________________ > > mesa-dev mailing list > > mesa-dev@lists.freedesktop.org > > https://lists.freedesktop.org/mailman/listinfo/mesa-dev _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
