Re: Large initrd and arch/ppc/boot/simple Question

Dear Kent,

in message [ref] you wrote:

We are booting our kernel via the arch/ppc/boot/simple mechanism to
package up our kernel and initrd.  It seems to work, until we get too
big.  What is big?  Roughly 8 MB for our one big uncompressed userland
program, plus the kernel, bash, busybox, and various userland
utilities.

Can initrd's get that large and still work?  Is the simple boot code
sensible with these sizes?  (I notice that the "avail ram" message
that gets printed is just hard coded number...)

I don't know  about  the  "simple  boot  code".  With  U-Boot,  we're
successfully  using  ramdisk  images which uncompress into 128 MB and
bigger filesystems. [And no, please don't ask me who needs that  many
stuff in a ramdisk, nor if there is not any better way to do this.]

Best regards,

Wolfgang Denk
