Eric, I change amdk8_scan_root_bus to: unsigned int amdk8_scan_root_bus(device_t root, unsigned int max) { unsigned reg; uint32_t value; /* Unmap all of the other pci busses */ printk_debug("\nbefore pci_scan_bus\n"); for(reg = 0xe0; reg <= 0xec; reg += 4) { value = f1_read_config32(reg); printk_debug("amdk8_scan_root_bus %0x = %0x max = %0x\n", reg,value,max); if((value>>24)>max) f1_write_config32(reg, 0); } for(reg = 0xe0; reg <= 0xec; reg += 4) { value = f1_read_config32(reg); printk_debug("amdk8_scan_root_bus %0x = %0x max = %0x\n", reg,value,max); } max = pci_scan_bus(&root->link[0], PCI_DEVFN(0x18, 0), 0xff, max); printk_debug("after pci_scan_bus\n"); for(reg = 0xe0; reg <= 0xec; reg += 4) { value = f1_read_config32(reg); printk_debug("amdk8_scan_root_bus %0x = %0x max = %0x\n", reg,value,max); } return max; } I think as least you only need to clear the regs that contain bigger bus number than the next bus for scanning. The result will be in the end. The problems: 1. It can not access 8151 on CPU link0 and so can not scan it 2. The HT scan seems can not figure out and set the link and read/write enable bit in e0. It set the e0 to 0x05050000 Regards Yinghai Lu Copying LinuxBIOS to ram. Jumping to LinuxBIOS. LinuxBIOS-1.1.52.0_Fallback Fri Dec 5 14:29:03 EST 2003 booting... Finding PCI configuration type.

Update to pirq_routing

The following is the diff for a change I made. I think the HAVE_PIRQ_TABLE is always defined and this allowed me to turn off the existence of a routing table.

Ron, Please check in the Tyan s2850/2880/2881/2882/4880 updates into the CVS Tree. 1. northbridge/amd/amdk8/raminit.h: change uint8_t to uint16_t 2. southbridge/amd/amd8111/amd8111_early_smbus.c: update smbus_write_byte 3. southbridge/amd/amd8131/amd8131_bridge.c: update ioapic_anable to enable PCI-X MASTER Mode. 4. other in /src/mainboard/tyan/ and /targets/tyan Stefan, With update 1 and 2, you can get ride of FAKE_SPD_ROM. You need to change some lines in auto.c for quartet. 1. I2C HUB address: 0x30 --> 0x18, 2. RC0-> (1<<1)<<8, RC1-> (1<<2)<<8, RC2-> (1<<3)<<8, RC3-> (1<<4)<<8. Regards YH.

After you clear that, I can not see the 8151 and > AGP in s2885. Hmm. This looks like a thinko. So right now the code says: unsigned int amdk8_scan_root_bus(device_t root, unsigned int max) { unsigned reg; max = pci_scan_bus(&root->link[0], PCI_DEVFN(0x18, 0), 0xff, max); /* Unmap all of the other pci busses */ for(reg = 0xe0; reg <= 0xec; reg += 4) { f1_write_config32(reg, 0); } return max; } And I think what I meant was: unsigned int amdk8_scan_root_bus(device_t root, unsigned int max) { unsigned reg; /* Unmap all of the other pci busses */ for(reg = 0xe0; reg <= 0xec; reg += 4) { f1_write_config32(reg, 0); } max = pci_scan_bus(&root->link[0], PCI_DEVFN(0x18, 0), 0xff, max); return max; } I don't have a clue why it works at all with clearing those registers after the pci bus scan. I wonder if that is the reason scan order matters because I don't clear those registers out first and things are dual mapped. Anyway my intention was to be very careful and to clear the HT chain mapping registers before we scanned them so we didn't have any old configurations getting in the way. Eric

Eric, I found in amdk8_scan_root_bus in northbridge/amd/amdk8/northbridge.c You put /* Unmap all of the other pci busses */ for(reg = 0xe0; reg <= 0xec; reg += 4) { f1_write_config32(reg, 0); } Why you need to clear that? After you clear that, I can not see the 8151 and AGP in s2885. PS: I have reversed the scan sequence to make sure HT scan 8111 at first and then 8151. Regards Yinghai Lu

Level 2 cache activation code?
by Svante Signell 04 Dec '03

04 Dec '03

Hello, I have recently upgraded my dual MSI-6120 from 2xCeleron (Mendocino) 300@450MHz with 2xMSI-6905 slot 370 to slot 1 adapters to one Celeron2 1.3GHz (Tualatin) using a Slot-T adapter card. The plan is to equip the mobo with 2xPIII or preferably 2xVIA C3 Nehemiah (when SMP capable). The problem is that the latest MSI BIOS (v2.0) for the mobo does not support Coppermine/Tualatin processors. The single GNU/Linux kernels boot without problems but _extremely_ slowly, at least with a speed reduction by a factor 10. hdparm -tT gives around 20/2 compared with 250/25 with the Mendocino CPU(s). For example uncompressing the kernel takes minute(s) compared to seconds. After some trials and web searching I suspect that the problem is with the level 2 cache not activated by the BIOS. I see the you have code in the linuxbios for activating caches. i) Does this code work for 440BX motherboards? ii) Is it possible to extract this code and try out after the kernel has booted (slowly), to verify my assumption? iii) Is there some other tool available for cache activation? iv) One interesting continuation would be to try to replace the MSI (AMI) BIOS with linuxbios, but as a first step I think this would be a little risky. Any ideas? Thanks, Svante

Doubt with Diskonchip millennium?
by Devi Priya 04 Dec '03

04 Dec '03

Hi, In the application note (AP044) from Msystems diskonchip it is given as: "The DiskOnChip Millennium is mapped into an 8KB memory window in the host platforms memory map. This 8KB window consists of four 2KB windows." Why is this mapping done? Is this done for all the DiskOnChip Millennium? The steps for BIOS is summarised as 1. After DiskOnChip Millennium BUSY# signal is negated, the CPU fetches the Reset Vector from the Boot-Block area, fetches the Boot Code stored there, and starts to execute the code. 2. Boot Code runs the first part of BIOS, initializing the basic hardware functionality. 3. Boot Codes loads the rest of the BIOS from the flash memory to the DRAM, and transfer control (jumps) there. 4. Chip Select of DiskOnChip Millennium is remapped from Reset Vector to BIOS expansion area. 5. CPU executes the rest of the BIOS code, including ROM expansion devices (among them, the DiskOnChip Millennium itself). 6. CPU calls OS bootstrap loader (INT19). 7. OS is loaded, and recognizes the DiskOnChip Millennium as the boot device. 8. OS loads the application code from the DiskOnChip Millennium and executes it. 9. Application software uses DiskOnChip Millennium exactly as if it were using a regular hard disk. In step 4 why is this remapping done _________________________________________________________________ Shop online for kids toys by age group, price range, and toy category at MSN Shopping.
