much better, Because don't need to cast conf to drivers_pci_onboard_config, it is not safe in pci_rom.c or pci_device.c Do it. YH How about we bring the device:rom_address back and in the driver_pci_onboard::enable_dev(dev) { dev->rom_address = conf->rom_address; } and in pci_get|set_resources() { if (dev->on_mainboard && dev->rom_address !=0) { /* do nothing */ else { allocate_rom_resource(); } } and in pci_dev_init() { if (dev->on_mainboard && dev->rom_address !=0) { rom = dev->rom_address; else { rom = pci_rom_probe(); } } Ollie > Also in get_pci_rom_resource begin > Add > > if(dev->on_mainboard) { > > struct drivers_pci_onboard_config *conf; > > conf = dev->chip_info; > > if(conf->rom_address!=0) { > > return; > > } > > } > > In Pci_set_resource end > Add > > if(dev->on_mainboard) { > > struct drivers_pci_onboard_config *conf; > > conf = dev->chip_info; > > if(conf->rom_address!=0) { > > pci_write_config32(dev, PCI_ROM_ADDRESS, > conf->rom_address | 1); > > } > > } > > Then We can remove that in pci_rom.c > > YH >

The chip.h is already in /drivers/pci/onboard. So may need to #include "../drivers/pci/onboard/chip.h" In pci_device.c Also in get_pci_rom_resource begin Add > if(dev->on_mainboard) { > struct drivers_pci_onboard_config *conf; > conf = dev->chip_info; > if(conf->rom_address!=0) { > return; > } > } In Pci_set_resource end Add > if(dev->on_mainboard) { > struct drivers_pci_onboard_config *conf; > conf = dev->chip_info; > if(conf->rom_address!=0) { > pci_write_config32(dev, PCI_ROM_ADDRESS, conf->rom_address | 1); > } > } Then We can remove that in pci_rom.c YH

I add driver/pci/onboard, it will take rom_address in conf. Also add some line in pci_rom.c /* for the onboard vga it already got one VGA rom space ? bug it should be allocated and just use the assigned value */ if(dev->on_mainboard) { struct drivers_pci_onboard_config *conf; conf = dev->chip_info; if(conf->rom_address!=0) { rom_address = conf->rom_address; } } Can you move that to pci_device.c ( allocate rom address)? I mean if it is on board, and have rom_address in Config.lb, it should use that instead of allocate one for it.

PCI VGA card works too
by Li-Ta Lo 11 Jan '05

11 Jan '05

Hello, I just made PCI vga cards works too. The problem is if the PCI card does not claim PCI IO resource, the bridge's IO enable bit in the command register is not enabled. Even with the legacy forwarding enabled in the bridge control, it still does not forward any legacy vga io. So the pci_bus_enable_resources() should be void pci_bus_enable_resources(struct device *dev) { uint16_t ctrl; /* enable IO in command register if there is VGA card * connected with (even it does not claim IO resource) */ if (dev->link[0].bridge_ctrl & PCI_BRIDGE_CTL_VGA) dev->command |= PCI_COMMAND_IO; ctrl = pci_read_config16(dev, PCI_BRIDGE_CONTROL); ctrl |= dev->link[0].bridge_ctrl; ctrl |= (PCI_BRIDGE_CTL_PARITY + PCI_BRIDGE_CTL_SERR); /* error check */ printk_debug("%s bridge ctrl <- %04x\n", dev_path(dev), ctrl); pci_write_config16(dev, PCI_BRIDGE_CONTROL, ctrl); pci_dev_enable_resources(dev); enable_childrens_resources(dev); }

The ATI card has PCI IO resource so there is no bogus resource in the northbridge. As the Nvidia card it does not have PCI IO resource so we got the 20000 to 1ffff thing. Ollie
