Hello all, has anyone gotten the SiS Mirage 1 chipset (SiS662/SiS964) that on the Intel D201GLY2 mini-itx board to work with sisfb and DirectFB?
I'm asking because while I can get perfectly fine 1280x1024x32bit output using the vesafb driver (which, alas, is much too slow to be usable in my DirectFB kiosk application which runs fine on via boards), the sisfb driver (while fast enough) produces interferences. Every 50 pixels or so there is a vertical line running from top to bottom of the screen (26 of the im total) which looks like its showing the content of another pixel column. Similary, when running the framebuffer console, the display irregularly repeats parts of the screen so that you see some kind of ghostly echo flickering in the background. I've tried toying around with the parameters, but the only thing that works so far is setting the framebuffer console to 8 bit depth which gives a clear picture (haven't tested with DirectFB as the apllication I'm using needs true-color graphics). Can this work as all? Or is there no support for the on-board graphics on this Intel board? The chip I'm using is listed via lspci as: |01:00.0 VGA compatible controller [0300]: Silicon Integrated Systems |[SiS] 661/741/760 PCI/AGP or 662/761Gx PCIE VGA Display Adapter |[1039:6330] (rev 04) (prog-if 00 [VGA controller]) | Subsystem: Intel Corporation Unknown device [8086:d61f] | Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- | Status: Cap+ 66MHz+ UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- | Interrupt: pin A routed to IRQ 10 | BIST result: 00 | Region 0: Memory at 40000000 (32-bit, prefetchable) [size=128M] | Region 1: Memory at 4a000000 (32-bit, non-prefetchable) [size=128K] | Region 2: I/O ports at 1000 [size=128] | Capabilities: [40] Power Management version 2 | Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) | Status: D0 PME-Enable- DSel=0 DScale=0 PME- | Capabilities: [50] AGP version 3.0 | Status: RQ=256 Iso- ArqSz=0 Cal=0 SBA+ ITACoh- GART64- HTrans- 64bit- FW- AGP3+ Rate=x4,x8 | Command: RQ=1 ArqSz=0 Cal=0 SBA- AGP- GART64- 64bit- FW- Rate=<none> | Kernel driver in use: sisfb I'm running Gentoo Linux, but currently with a self-compiled stock kernel 2.6.27.7, I've tried with the Gentoo stock 2.6.26 as well without any difference.
