That's right. AFAIK, The 2.6 kernel is not yet supported by the Xilinx EDK tools; and so it cannot generate a 2.6 BSP. If you want to use the generated BSP; use the montavista 2.4 kernel. > And also, I saw this thread: "Migrate Xilinx Vertex support from the OCP > bus to the platfom bus" > > http://patchwork.ozlabs.org/linuxppc/patch?id=3933 > Does it mean all of onchip peripherals for Virtex-4 FX must reside on the > PLB bus instead of OPB (OCB) bus ? No. Platform bus is a Linux construct to make it simpler to handle "directly attached" devices. ie. Anything that the processor can access directly w/o PCI et all. OPB and PLB devices are both 'platform' devices in Linux 2.6 terminology. > (i.e. during the process of creating the ref design for Linux using Xilinx > Platform studio, I have to select PLB peripherals instead of OPB > peripherals. Is is correct ?) No, use whatever peripherals you want (either PLB, or OPB). Just be prepared to port device drivers for anything beyond a serial port. > > BTW, do you have a sample ref design for ML-403 board for Xilinx Platform > studio ? Why not use the ref design that Xilinx provides? (I have a number of designs that work; but most of the time I use the ML403 ref design because I know it's proven) Cheers, g. -- Grant Likely, B.Sc.

question about Linux 2.6 with Xilinx ML-403
HI, Grant, It looks like that the patch for ML-403 in Linux 2.6.17 kernel(I downloaded from Linus git tree) does not have the directory : ./arch/ppc/platform/4xx/xilinx_ocp like the one in the 2.4.30 kernel. And also, I saw this thread: "Migrate Xilinx Vertex support from the OCP bus to the platfom bus" http://patchwork.ozlabs.org/linuxppc/patch?id=3933 Does it mean all of onchip peripherals for Virtex-4 FX must reside on the PLB bus instead of OPB (OCB) bus ? (i.e. during the process of creating the ref design for Linux using Xilinx Platform studio, I have to select PLB peripherals instead of OPB peripherals. Is is correct ?) BTW, do you have a sample ref design for ML-403 board for Xilinx Platform studio ? Thanks for the help. -- Ying Ding Grant Likely wrote: >On 4/7/06, yding wrote: > > >> HI, Grant, >> >> I found this message : >>http://patchwork.ozlabs.org/linuxppc/patch?id=3841 on >>Internet. >> It looks like you created some patch files for supporting Linux 2.6 with >>Xilinx ML-403. >> >>how can download the whole kernel source tree with your patched files (via >>cvs or bitkeeper) ? >> >> > >I believe they are now in Linus' mainline git tree.

question about Linux 2.6 with Xilinx ML-403
Grant, I checked both Torvalds' tree and Paul's tree. I see the defconfig file for both ml300 and ml403, but I don't see any source files related to either ml300 or ml403 under the subdirectory. Have you done a complete BSP for either ml300 or ml403?

Yes, we have a driver for the PLB TEMAC (different than the GSRD LL TEMAC) for Linux 2.4 (MontaVista Linux 2.4.20) that's shipped in EDK 8.1.1, and MontaVista is on the verge of publishing a driver for PLB TEMAC for Linux 2.6.

question about Linux 2.6 with Xilinx ML-403
HI, Grant, I downloaded Paul's git tree as you suggested. It seems that the defconfig for ML-403(in Patch [9/9]: http://patchwork.ozlabs.org/linuxppc/patch?id=4226 ), the tri-mode Ethernet MAC on Virtex-4 FX12 on the ML-403 board was disabled. Is this Ethernet device supported by this patch ?

question about Linux 2.6 with Xilinx ML-403
Grant, I know I could probably figure this out by looking at the GIT tree directly (which I'm planning to do) but could you summarize how much (which devices) of the ML-403 is supported by your patches? Serial? (which Xilinx core) Ethernet? (Hard-Core PLB TEMAC?, Soft-Core PLB EMAC? Localink TEMAC? Is 10/100/1000 supported, or is there only 1 rate e.g. 1000 supported?)
