If I changed config.lb PCI 1:0.2 on --> PCI 1:0.2 off The PCI 1:0.0 and PCI 1:0.1 will be disabled together. According to AMD 8111 data sheet, LPC 0x48, only can be disabled the device in second bus by device num, and the three USB share one device number. So I guess the code about 0x47 must be there.

According to AMD, USB 2 in amd8111 will never work.

This disabling is fine if the kernel can later re-enable, but I doubt the kernel will do that. We need a way to make this usb enable/disable visible at configuration time, so people can turn on/off as needed, unless usb2.0 on the 8111 NEVER work. I am willing to guess it will work someday, and this built-in disable will come back to bite us. ron

David, Please refer to the patch for 2.4.22 and 2.6.5, or you can put that in CVS ... Also please refer to the matix to see which kernel you want to use. Please make sure enable ati xl framebuffer only in kernel config. ( don't enable noinit) Regards YH -----邮件原件----- 发件人: Hendricks David W.

We are going to implement a slightly better one soon. Actually, the enable/disable for devices in amd8111 is multiplexed in amd8111_enable and the device_operation::enable() is directed to amd8111_enable. We are going to demultiplex this and each devices has its own "real" enable method. Ollie

I add some lines in amd8111, if USB2 is disabled, it will don't touch 0x48, only touch 0x47. if ((dev->vendor == PCI_VENDOR_ID_AMD) && (dev->device == PCI_DEVICE_ID_AMD_8111_USB2)) { if(!dev->enabled) { byte = pci_read_config8(lpc_dev, 0x47); byte |= (1<<7); pci_write_config8(lpc_dev, 0x47, byte); return; } } reg = reg_old = pci_read_config16(lpc_dev, 0x48); reg &= ~(1 << index); if (dev->enabled) { reg |= (1 << index); } if (reg != reg_old) { pci_write_config16(lpc_dev, 0x48, reg); } -----邮件原件----- 发件人: Li-Ta Lo [mailto:ollie@lanl.gov] 发送时间: 2004年5月5日 10:28 收件人: YhLu 抄送: ron minnich; Stefan Reinauer; LinuxBIOS 主题: Re: 答复: 答复: 答复: Disable USB2 in AMD8111 and remove ide hardcode io addr On Wed, 2004-05-05 at 10:51, YhLu wrote: > If I changed config.lb > PCI 1:0.2 on --> PCI 1:0.2 off > The PCI 1:0.0 and PCI 1:0.1 will be disabled together. > > According to AMD 8111 data sheet, LPC 0x48, only can be disabled the device > in second bus by device num, and the three USB share one device number. > > So I guess the code about 0x47 must be there. > Ron and I just dicurssed about the enable/disable mechanism for amd8111.

I change my mind, disable that in Config.lb is better and less code.

If AMD is certain about that, and no one else objects, I remove any concerns I have about this code. But please put in a more informative comment such as "will never work" thanks ron

Ron, I'm going to add several lines in amd8111_enable of amd8111.c to disable USB2 in amd8111. /* disable usb2 in amd 8111 because it does not work awlays*/ byte = pci_read_config8(lpc_dev, 0x47); byte |= (1<<7); pci_write_config8(lpc_dev, 0x47, byte); Also will remove several lines in amd8111_ide.c /* The AMD768 has a bug where the BM DMA address must be * 256 byte aligned while it is only 16 bytes long. * Hard code this to a valid address below 0x1000 * where automatic port address assignment starts. * FIXME: I assume the 8111 does the same thing. We should * clarify. stepan(a)suse.de */ pci_write_config32(dev, 0x20, 0xf01); pci_write_config32(dev, 0x48, 0x205e5e5e); word = 0x06a; pci_write_config16(dev, 0x4c, word); and add byte = 0x20 ; // Latency: 64-->32 pci_write_config8(dev, 0xd, byte); regards YH

Which kernel for framebuffering?
by Hendricks David W. 04 May '04

04 May '04

We were able to build and boot LinuxBIOS with VGA support for an HDAMA. FILO came up on screen and the keyboard worked, but we've been unable to get Linux framebuffering to work using a 64-bit kernel. We were wondering if there's anything special you had to do to make it work, or any special kernel version or patches we need to use.
