PCI devices: IRQ table and vendor/device ID
by Andrea May 29, 2008

May 29, 2008

Dear OFW developers, I'm going to a "new" PCI device on our custom (Geode LX based) board. I already add standard PCI support to our build (${BP}/dev/pcibus.fth), plus enabling some debugging stuff: true value pcimsg? true value probemsg? Is it possible to see its vendor/device ID from OFW? (we are going to create a custom OFW driver soon, but it will be enough to see it IDs for debugging purpose) AFAIK I also have to add "something" on PCI IRQ table to let the OS (in our case Linux) to attach its driver to the right IRQ. I found something like that inside vsapci.fth source (cpu/x86/pc/*/vsapci.fth) but it seems that this is used only for Geode companion chip devices. Any clue in how enumerate and assign IRQ to PCI devices with OFW? Thanks in advance and best regards, -- Andrea DAVE Srl - Electronics System House e-mail address: r&d4(a)dave-tech.it

LPC Flash programming
by Andrea May 29, 2008

May 29, 2008

Dear OFW developers, I've found that inside dev/geode/lpcflash.fth it seem there is the Forth code to program an LPC Flash. I try to use it (like on OLPC) but I have the following undefines: ./build neptune.rom --- ${BP}/cpu/x86/pc/neptune/devices.fth is newer than the target file fw.img --- Rebuilding fw.img --- Cmd: /home/shared/devel/neptune/sw/ofw/openfirmware.git/cpu/x86/Linux/x86forth /home/shared/devel/neptune/sw/ofw/openfirmware.git/cpu/x86/build/basefw.dic ../fw.bth ${BP}/dev/geode/lpcflash.fth:57: ?file ? ${BP}/dev/geode/lpcflash.fth:68: /flash ? ${BP}/dev/geode/lpcflash.fth:70: flash-buf ? ${BP}/dev/geode/lpcflash.fth:74: get-file ? --- Saving fw.dic ... --- Saving fw.img ... --- fw.img is newer than the target file neptune.rom --- Rebuilding neptune.rom --- Cmd: /home/shared/devel/neptune/sw/ofw/openfirmware.git/cpu/x86/Linux/forth /home/shared/devel/neptune/sw/ofw/openfirmware.git/cpu/x86/Linux/../build/builder.dic ../neptune.bth --- Saving as neptune.rom - Direct ROM format As far as I understand this are dependency that are declared inside: dev/olpc/spiflash (due the fact that on OLPC LPC flash is an SPI flash connected via KB3700, correct me if I'm wrong) Can this lpcflash.fth device be used for a "standard" LPC flash too? or it's only some kind of "wrapper" for the OLPC's SPI flash?
