Hardware Help with diskonchip?
by Devi Priya 08 Dec '03

08 Dec '03

Hi, In the application note (AP044) from Msystems 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 mapping done in hardware? I use diskonchip millennium (8MByte MD2800). Then shouldn't the entire 8MB shall be mapped in hardware to the physical address space? 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? Is this mapping done in hardware? In my setup, the diskonchip is mapped in hardware to the higher order address (0xFFFFFFFF-0xFF800000). SDRAM mapped to lower address (0x00000000-0x1FFFFFF). What else modification do i require in HARDWARE to use diskonchip millennium? _________________________________________________________________ Add zing to Hotmail.

Will this work ??

Hi there, I've a Gigabyte GA-7NNXP with nForce II Chipset, and a BIOS with a size of 512 KB. Will I be able to get a open source "bios" work on that mainboard ? thx for your helping!!

Eric, Great, it works. Even normal scan it can find out 8151. But the bus number is funny, I may need to update bus number mptable.c and irq_table.c and reset.c I wonder if 8151 on CPU 1 and 8131/8111 on CPU0. is the amdk8_scan_root_bus called two times? If so, you may keep the > 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); > } Regards YH. -----邮件原件----- 发件人: ebiederman(a)lnxi.com [mailto:ebiederman@lnxi.com] 发送时间: 2003年12月5日 15:26 收件人: YhLu 抄送: ron minnich; Stefan Reinauer; linuxbios(a)clustermatic.org 主题: Re: Tyan S2885 YhLu <YhLu(a)tyan.com> writes: > 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.

The Opteron is too forgiving when you only have one link. It makes this kind of debugging a pain. What I am doing should not work but it does in that case... My apologies, for missing this. In amdk8_scan_chains() there is the snippet: config_busses &= 0x0000ffff; config_busses |= ((dev->link[link].secondary) << 16) | ((dev->link[link].subordinate) << 24); f1_write_config32(config_reg, config_busses); Which is the offending piece of code. It neither sets the link that we are supposed to go out, nor does it set the r/w enable bits. Ouch. It only works if those registers are pre programmed. So I think this should be: config_busses &= 0x000fc88; config_busses |= (3 << 0) | /* rw enable, no device compare */ (( nodeid & 7) << 4) | (( link & 3 ) << 8) | ((dev->link[link].secondary) << 16) | ((dev->link[link].subordinate) << 24); f1_write_config32(config_reg, config_busses); Eric

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.

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

arima hdama success

I got the latest snapshot this evening, built for the arima hdama, and it fails the same way it has failed (hangs after printing out stuff below) for the last couple of months. Have Yh Lu's changes that fix the arima hdama been committed? If not, could someone point me to the changes that fix whatever this problem is?
