[PROPOSAL] extended payload handling
by Stefan Reinauer 21 Jun '04

21 Jun '04

There has been a similar proposal on this list a while ago, but nothing happened so far, so I want to put this pack to discussion. Objectives ---------- 1.) LinuxBIOS is kind of hard to set up for project newbies, since it does not only require manually tweaking the configuration files for basically every situation, but also necessarily needs an external payload to do anything useful. LinuxBIOS currently sets a high barrier due to the modular concepts it uses. - LinuxBIOS itself is sometimes very sensitive to the build environment. See requirement for setting LANG for example. - For a project outsider it is hard to determine the best payload solution for a specific purpose. There is basically no information except the mailing list archives. - Config files have to be tweaked to explicitly suit the user's directory structure. There is no proposal, nothing that works out of the box. One just _has to_ edit the config files. - LinuxBIOS requires the user to specify a size for the payload instead of determining the required size and doing the needed calculations itself. This is very hand-crufted and can be pretty mind wasting. 2.) LinuxBIOS can currently execute one payload. For greater flexibility and isolated development cycles of the firmware related code parts/projects LinuxBIOS should allow payload chains, ie. executing multiple payloads one after the other. LinuxBIOS wants to keep up it's modularity, letting each module do it's job. This possibility of not doing more than one task should be passed on to the payloads. Solution -------- Feature plugins like "testbios" should not be merged into LinuxBIOS' core code. Instead they should be implemented as a payload. Since we want to load an operating system later on, we also need to be able to load more than one payload. Implementing ELFLOAD in each such plugin is inadequate. Instead LinuxBIOS should execute multiple payloads the same way it executes multiple "drivers" now. * LinuxBIOS therefore needs a way to automatically determine payload sizes when building the image and later when executing payloads. Hardcoding the size values in the config files is inadequate and will lead to unnecessary overhead * LinuxBIOS at runtime needs to go through the list of available payloads, either by having a linked list of payload start points or by scanning the flash rom. * LinuxBIOS should, to be consequent, remove all streaming code except CONFIG_ROM_STREAM * Payloads should have the possibility to add their own enhancements to the LinuxBIOS table. * A least one payload should be "default payload" with the possibility to build this automatically and link it into the image. This is why I checked the "util/extensions" directory into v2 during the last discussion. It should hold possible choices to payloads that can automatically be built and included. Potentially one could add more payloads by symlinking their source tree to this directory to make it available to LinuxBIOS without major reconfiguration. People feel a lot safer with creating a symlink than with changing config files they do not fully understand. Since these can later be executed in row by elfboot, the minimum overhead design of LinuxBIOS itself will not be hurt. At this point I want to put an idea to discussion: If we are going more and more modular and some of us think the current tree is too bloated: Why do we not modularize code like pci resource allocation into a payload as well. My favorite bootloader may already do this and I can't stand this bloat everywhere, you know ;) Even though this may sound funny, I am serious about this issue. I do not see why allocating PCI resources should really be part of the lowlevel code, except for the fact that the NEXT payload in row, potentially Linux itself is too stupid to do that. Bummer. * LinuxBIOS configuration should have an easier mechanism for choosing payloads from the "default" directory, allowing them to be built automatically. Right now I am doing: cd filo-0.4.2 linux32 make CC="gcc -m32" LD="ld -melf_i386" cd .. freebios2/targets/buildtarget amd/solo $PWD/freebios2 cd build-solo make cd .. cp build-solo/solo.rom . My target Config.lb comes with these constructs: target ../../../../build-solo payload ../../filo-0.4.2/filo.elf So I build everything completely out of the freebios2 tree, because building in-tree sucks. The only thing left is to get filo and the other payloads to build out-of-tree as well. Comments? Discussion? Assassination attempts? Stefan

Question about AGP
by Dave Ashley 19 Jun '04

19 Jun '04

Is the bios supposed to initialize the AGP registers? I'm trying to get AGP working for EPIA-M. I'm wondering if linux itself takes care of everything or whether the bios has to initialize some stuff. -Dave

RE: Question about AGP
by M. Renee Hopkins 18 Jun '04

18 Jun '04

AGP worked with linuxbios V1 a couple months ago, but didn't seem to go into 4X, but stayed in 1X I believe. Also, I tried IVTV, but linuxbios didn't set the PCI card to 'bus master'. Any tips would be appreciated. I've not tried V2. >From: Dave Ashley <linuxbios(a)xdr.com> >To: linuxbios(a)clustermatic.org >Subject: Question about AGP >Date: Fri, 18 Jun 2004 07:26:40 -0700 > >Is the bios supposed to initialize the AGP registers? > >I'm trying to get AGP working for EPIA-M.

Future support for Nvidia "Crush" CK8-04 (AMD-8111 replacement plus)?
by Ken Fuchs 18 Jun '04

18 Jun '04

Hi, The "Crush" CK8-04 is an interesting AMD-8111 "replacement" that adds PCI Express x20, USB 2.0, SATA-150, GbE, 24-bit 96KHz 7.1 audio to what the AMD-8111 provides (broken USB 2.0): http://www.xbitlabs.com/news/chipsets/display/20040405142953.html Is anyone out there interested in LinuxBIOS support for this chip? What are the prospects of LinuxBIOS supporting this chip? Iwill which has been working with Nvdia on this chip will release its dual Opteron mainboard DK8E based on the CK08-04 in August/Sept: http://www.xbitlabs.com/news/chipsets/display/20040526125019.html Sincerely, Ken Fuchs <kfuchs(a)winternet.com>

Don't worry. Maybe before you get the MB, the LinuxBIOS for the chipset is ready, but it's in Tyan MB (S2895). Nvdia has promised to us that it will help us to get it done.

IBM now has a Linux notebook with Tier1 support. Maybe this is a laptop to get LinuxBIOS up on. http://www.theinquirer.net/?article=16550 http://www-132.ibm.com/webapp/wcs/stores/servlet/CategoryDisplay?categoryId… Anyone have one of these yet? -Bari

We have several ports that are routinely smacking up against the 64K limit during development. The last E7501 port I did in the freebios1 tree LinuxBIOS was running about 40K. With romcc inlining everything we are worse in the freebios2 tree. As far as bloat baring Stefan's concerns about redundancy between LinuxBIOS and OpenBIOS (the resource allocation code). Is not so much about the features we have to day, but more a feeling much more will be the pebble that starts the avalanche. Or maybe we feel we have seen the pebble, and we are watching it bounce downhill with dread. The bottom line is that to keep size under control you constantly have to be paying attention to size, just as you have to constantly watch correctness and performance. The long term trends in the industry are for very slow romsize growth. Anyway even at 32K you are twice as big as my cat :) ls -l /bin/cat -rwxr-xr-x 1 root root 15000 2003-10-04 17:10 /bin/cat* Eric _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

答复: Building Tyan AMD64 s2882 Linux BIOS
by YhLu 16 Jun '04

For Linux based Server, LinuxBIOS would be better than any other commercial BIOS. OS has been in GPL, So BIOS should be there too.

I get the code and did do anything with it until now. I will update the code and try again. I will try Redhat 9.0, last time I try it, I saw the version of GCC on redhat 9.0 is lower than the required version mentioned by LinuxBIOS-AMD64, Author by Stefan Reinauer I'm not fully understand the paylod idea yet, but I will do some research on my side. I'm really appriciate the response you guys have given to me. I'm starting to feel much more confident with LinuxBIOS now. Some people in my company is a little hesitate about the LinuxBIOS as we use Phoenix BIOS before and afraid of the free Software, I will make a strong case for them because the good community I saw here.
