At the moment I am looking at x60's romstage.c because I'd plan to copy as much as possible from it. At the function static void ich7_enable_lpc(void) I got stuck. I can make some guesses, but don't know where the details are documented. If you could point me to any documentation, I'd love to read it. I tried ich7 datasheet and LPC Interface Specification but did not spot what the function ich7_enable_lpc does. By comparing the output of lspci -nnvvvxxx -s 00:1f.0 on the Thinkpad with coreboot and the Macbook with factory bios I get the following: on the Thinkpad $ lspci -nnvvvxxx -s 00:1f.0 00:1f.0 ISA bridge [0601]: Intel Corporation 82801GBM (ICH7-M) LPC Interface Bridge [8086:27b9] (rev 02) Subsystem: Lenovo ThinkPad T60/R60 series [17aa:2009] 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- Latency: 0 Capabilities: [e0] Vendor Specific Information: Len=0c <?> Kernel driver in use: lpc_ich Kernel modules: intel_rng, lpc_ich, leds_ss4200 00: 86 80 b9 27 07 00 10 02 02 00 01 06 00 00 80 00 10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20: 00 00 00 00 00 00 00 00 00 00 00 00 aa 17 09 20 30: 00 00 00 00 e0 00 00 00 00 00 00 00 00 00 00 00 40: 01 05 00 00 80 00 00 00 81 04 00 00 10 00 00 00 50: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 60: 80 80 80 80 d0 00 00 00 80 80 80 80 00 00 00 00 70: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 80: 10 02 0d 1f 01 16 7c 00 e1 15 0c 00 81 16 1c 00 90: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 a0: ac 06 00 00 30 00 00 00 13 1c 0a 00 00 03 00 00 b0: 00 00 f0 00 00 00 00 00 00 00 02 0a 00 00 00 00 c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 d0: 33 22 11 00 67 45 00 00 cf ff 00 00 08 00 00 00 e0: 09 00 0c 10 b4 02 24 17 00 00 00 00 00 00 00 00 f0: 01 c0 d1 fe 00 00 00 00 86 0f 02 00 00 00 00 00 and on the Macbook $ lspci -nnvvvxxx -s 00:1f.0 00:1f.0 ISA bridge [0601]: Intel Corporation 82801GBM (ICH7-M) LPC Interface Bridge [8086:27b9] (rev 02) Subsystem: Intel Corporation Device [8086:7270] 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- Latency: 0 Capabilities: [e0] Vendor Specific Information: Len=0c <?> Kernel driver in use: lpc_ich Kernel modules: intel_rng, lpc_ich, leds_ss4200 00: 86 80 b9 27 07 00 10 02 02 00 01 06 00 00 80 00 10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20: 00 00 00 00 00 00 00 00 00 00 00 00 86 80 70 72 30: 00 00 00 00 e0 00 00 00 00 00 00 00 00 00 00 00 40: 01 04 00 00 80 00 00 00 01 05 00 00 10 00 00 00 50: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 60: 80 80 80 80 d0 00 00 00 80 80 80 80 00 00 00 00 70: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 80: 10 00 07 38 81 06 0c 00 41 16 0c 00 00 00 00 00 90: 01 03 1c 00 00 00 00 00 00 00 00 00 00 00 00 00 a0: 04 02 00 00 01 00 00 00 13 1c 0a 00 00 03 00 00 b0: 00 00 f0 00 00 00 00 00 08 80 00 00 00 00 00 00 c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 d0: 33 22 00 00 67 45 00 00 00 ff 00 00 00 00 00 00 e0: 09 00 0c 10 b4 02 24 17 00 00 00 00 00 00 00 00 f0: 01 c0 d1 fe 00 00 00 00 86 0f 02 00 00 00 00 00 In the Thinkpad output I can spot the values written by coreboot: 0xd0 at 0x64 // Enable Serial IRQ, this is the same for what the Macbook outputs, but where can I read that this enables serial IRQ? 0x0210 and 0x1f0d at 0x80 and 0x82 // decode ranges, the Macbook outputs different values here 0x1601, 0x007c, 0x15e1, 0x000c, 0x1681, 0x001c from 0x84 to 0x8e // the Thinkpad has three ranges while the Macbook seems to have two ranges only with differnt values. So how would I modify the ich7_enable_lpc function? Should I try to reproduce what the factory bios sets? Other from the values set in this function a few more values differ between the two computers. Better than guessing I would prefer to somewhere read about what these settings do. I just don't know where. any help is truely appreciated with best regards Mono -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
