[Bug 349992] Re: [945 tiling] Low performance due to no A17 workaround

[Svetlozar Argirov]

Obvious performance boost with 30rc2. Card is :

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)
	Subsystem: Toshiba America Info Systems Device 0001
	Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
	Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
	Latency: 0
	Interrupt: pin A routed to IRQ 16
	Region 0: Memory at ffd80000 (32-bit, non-prefetchable) [size=512K]
	Region 1: I/O ports at cff8 [size=8]
	Region 2: Memory at e0000000 (32-bit, prefetchable) [size=256M]
	Region 3: Memory at ffd40000 (32-bit, non-prefetchable) [size=256K]
	Capabilities: <access denied>
	Kernel modules: intelfb

After switching to 30rc2 glxgears went from ~120fps to over 1000fps.
Also performance of Compiz & Flash sites, and especially fullscreen
video is much, much better.
