Re: [LinuxBIOS] Tyan s2892 the OLPC way

[Lu, Yinghai]

Please check the build payload for amd64.

It includes: IDE, and SATA(nvidia). And only 32kbytes left.  ---- assume
1Mbytes space, and linuxbios will use 96kbytes.

Todo:

put the kexec tools into the initrd... (32kbytes)

Hope to use ron't update mkelfImage to get more 32kbytes for kexec tools

Ron,

Where is patch for mkelfImage that can take vmlinux instead of bzImage?

do i need kexec-boot-loader?

yes

If you look in deploy, for now, you can use the payload, which is built
without containing linuxbios or vsa. That is how I got a working payload
for ultra40.

What we need to do with buildrom is extend it so we can have a config
file for a given platform, that builds the proper kernel AND linuxbios,
and has payloads like VSA as an OPTION. I think this is easy. I did it
(sort of) for qemu.

Why do you need kexec in the ROM? Is there a good reason not to put it on
the same device that holds the kernel you'll kexec to?

The binary might come in over a network such as infiniband. You can't really
assume much about where the kernel is.

kexec and the program are small, I think the cost is ok.

[Myles Watson]

Sure,

As long as you can fit it. This version removes ACPI support from the kernel
so that the compressed payload is now 779K.

Hi Myles,

can I remove the patches from the wiki, instead linking to the
respective files in the mailing list archive?
http://www.linuxbios.org/pipermail/linuxbios/

No need to duplicate the information in the wiki if it's already in the
archives...

Uwe.

Yes please!

Patches should be kept in the tracker (tracker.linuxbios.org), or on the
mailing list, until everyone is using the tracker.

Can the tracker pick up patches from the mailing list
automatically?  Also, can it send all changes in whatever
is tracked to a mailing list?

No, please go the other way round. Tracker is the first place for
patches now.

it does that.
