答复: Prefmem of bus 3
by YhLu 05 Mar '04

Some time you said that arima board connect all PCI-X slots of amd 8131 irq to amd 8111 ioapic intead of 8131. So even disable ioapic of 8131, device on PCI-X still works properly. After enable ioapic of 8131, devices that are not using prefmem works well.

I wonder if why this work on LANL clusters and not on others is the result of code skew. Lightning nodes with myrinet only seem to have one prefmem region. Yet another reminder that I really need to finish syncing up the code bases. Eric

PCI card bios accessibility
by Tina Declerck 04 Mar '04

04 Mar '04

Hello, I am new to this list so I apologize if this question has already been answered. I didn't see it in the archives. - Does the Linux BIOS do discovery on PCI slots for the existance of cards? - Will it use PCI configuration space to locate the Basic Address Register (BAR) to locate bios on a PCI card and load it? Specifically, this is regarding a 3ware RAID card.

Question on LinuxBIOS Bios Stack
by Heiko Joerg Schick 04 Mar '04

04 Mar '04

Hello, I can remember that (I think) 6 month ago, a system call LOBOS was used to boot the later used Linux Kernel. Now I saw in the document "Flexibility in ROM: A Stackable Open Source BIOS" that a quite more complex firmware stack is used, with the following components: - LinuxBIOS - ADLO - Grub Bootloader - Windows 2000, Linux, ... I this always the case and how it is realized on other platforms, like PowerPC??? Thanks in advance !!! Regards, Heiko

EPIA-M 6000 or M-10000 Frame buffer + linuxbios +/- VGA

Does anyone have a working snapshot of this? I've tried building the list from 2003-07-05 cvs and patch of Ashley, as well as cvs co of freebios2 tree and found varying degrees of limited success. If someone on the list has a working snapshot or pointer, that could save some time here. I appreciate and commend all those who have worked on this great project. The boots done here using freebios v1 and v2 come in under several seconds to init level 3. This project has great potential. Many thanks in advance. M.

BIOS calls
by Daniel Sheltraw 03 Mar '04

Hello LinuxBIOS list Does LinuxBIOS have a protected-mode API that can be used in kernel-space to config devices similar to the old DOS-based BIOS calls in real-mode? Thank you, Daniel Sheltraw

Some devie has two mem regions( non-pref) and it works. -----邮件原件----- 发件人: ebiederman(a)lnxi.com [mailto:ebiederman@lnxi.com] 发送时间: 2004年3月1日 13:07 收件人: Li-Ta Lo 抄送: ron minnich; YhLu; LinuxBIOS 主题: Re: Prefmem of bus 3 Li-Ta Lo <ollie(a)lanl.gov> writes: > I think there is some problem in the resource allocation code so it can > not handle devices with 2 prefmem. Maybe. I know there was some kind of problem on the opteron, early on but I forget what. The code for all resource types is the same so if we can handle two resources on a bus of the same type it should not be quite as simple as that. > Is the code just picking the "largest" resource ? I am really confused > by the code in devices.c No. The code should be quite simple but it is recursive and highly abstracted which makes it hard to follow. The high level overview is the code works in two passes. The first pass is to determine the size of the resource window needed. The second pass is to determine the actual resource assignments. There are many was to assign resources on a bus. After some experiences with tight memory situations I implemented a near optimal solution. The solution is optimal if all of your resources are a power of 2 in size. Basically the code is a loop. For each iteration the code finds the largest unassigned resource. Then the resource constraints of that resource are considered and padding between the previous resources and the current resources are inserted if necessary. Then we get into the next iteration. The reason this is optimal if all of your resources are a power of two in size is because if your previous resource is a larger or equal power of two no padding will be needed for the current resource. The situation Yhlu has is below and it is weird. The resources are assigned properly but when the are clumped together into a range register on the bus that value is incorrect. Which is very weird. YhLu has: ASSIGN RESOURCES, bus 3 PCI: 03:03.0 10 <- [0xe0000000 - 0xefffffff] prefmem PCI: 03:03.0 18 <- [0xf0000000 - 0xf3ffffff] prefmem And then on bus 2: PCI: 01:02.0 24 <- [0xe0000000 - 0xffffffff] bus 3 prefmem The bus 3 prefmem should be PCI: 01:02.0 24 <- [0xe0000000 - 0xf3ffffff] bus 3 prefmem So it looks like stuck bits or something. Ollie can you get a boot log from Orange? Unless they are different types of infiniband adapters things should be fairly comparable. Eric

Quick linux question
by Dave Ashley 01 Mar '04

01 Mar '04

This is off-topic but I'm hoping someone here will know the answer. In the linux kernel I need to make a module that will map the BOOTROM of an RTL8139 based network card into PCI memory somewhere. I need to write the pci config longword at offset 0x30 with the bus address. I can arbitrarily pick one such as 0xd2000000 and the bootrom appears as expected, but I don't want to step on anything else that might be using that memory area. How can I allocate a block of memory in pci address space to know where to safely map in the bootrom? Also I'll want to free the allocation on module exit. Apologies/thanks as the case may be. -Dave
