that last code I sent

still is not quite right. It can be simpler I just realized. I can look at the bridge_ctl and if vga is set, I should be able to figure out that it needs to be set in amdk8. Off to look some more. ron

Built by linuxbios, arima mobo, linuxbios support from linux networx. Tyan will sell you K8 mobos with linuxbios on them. Hopefully the tyan people reading this will get in touch with you. There are a few other companies that will do K8 mobos with linuxbios but nothing public yet. ron _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

答复: Tyan S2885 + K8 + Nvidia GEForce FX 5600 + testbios: WORKS!
by YhLu 14 Jan '04

Great, I would have a try. So the vgabios will be in the tree. How about the util/testbios? YH. -----邮件原件----- 发件人: ron minnich [mailto:rminnich@lanl.gov] 发送时间: 2004年1月9日 14:35 收件人: linuxbios(a)clustermatic.org 主题: Tyan S2885 + K8 + Nvidia GEForce FX 5600 + testbios: WORKS! We just brought up an AGP card using the freebios/util/vgabios/testbios code! It's an Nvidia and it works fine. I think the emulator path is going to work for linuxbios. There are still some sharp corners to round off but this is really exciting. This is as far as we have ever come with VGA support that will work safely and across all architectures. I will be putting a fix into the linuxbios resource code to deal with the problems we encountered. It is a trivial fix. It is amazing how well the resource setup code in V2 is working, however; bridges and things just tend to get set up correctly. Anyway, just thought you'd all want to know. ron _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

For VGA ...
by ron minnich 14 Jan '04

14 Jan '04

VGA is "special". This code: src/devices/device.c:static void allocate_vga_resource(void) is great. This loop: while(bus) { bus->bridge_ctrl |= PCI_BRIDGE_CTL_VGA; bus = (bus == bus->dev->bus)? 0 : bus->dev->bus; } is close, but as noted it is somewhat pci-centric. It works darned well though: it sets up most bridges just fine. But VGA is just so darned "SPECIAL". I am thinking of adding a new device_operation just for good old vga. void (*endable_vga)(dev, vga_dev) The loop changes to this: while(bus) { if (bus->dev->ops && bus->dev->ops->enable_vga) bus->dev->ops->enable_vga(bus->dev, vga); else bus->bridge_ctrl |= PCI_BRIDGE_CTL_VGA; bus = (bus == bus->dev->bus)? 0 : bus->dev->bus; } I think this is all we need. Most of the devices would have this empty, but the amdk8 would have an entry so it could: - set the VGA_EN bit in the correct PCI I/O register - set up an MMIO pair for the a0000-affff range I realize this is a special case, but all of vga is a special case, and VGA is *very* *important* to the embedded space. Our goal is to have a VGA filo or etherboot prompt. comments? Absent serious objections I want to put this in today. ron

Can someone tell me the location of the SiS patch for linux 2.4.7? Or, if a later version of Linux is available, the patch to that one. Ted

答复: DIMM relocation on Tyan S2885
by YhLu 12 Jan '04

After ron solve the VGA support on LinuxBIOS and We must make sure the performance meet some degree, We can talk about remapping the AGP ram in to some other range.

V2 EPIA compilation problem
by Dave Reader 12 Jan '04

12 Jan '04

Hi, Having built V1 for epia, I wanted to try V2. I'm hitting the following problem with romcc segfaulting when trying to build. The buildhost is Debian Stable on a P4 machine. I have upgraded binutils to 2.14.90 & gcc to 3.3 in case the problem lie there, but i still have this problem. I've seperated out the gcc options show below for readability. What am I doing wrong?
