[PATCH 0/1] routerstationpro: move board off 3.4 and onto the 3.8 kernel

[michel.thebeau]

Hi,

linux-yocto-3.8 kernel is updated for Routerstation Pro, so that the bsp
can moved to that kernel.

https://lists.yoctoproject.org/pipermail/linux-yocto/2013-April/000546.html

"Feel free to update the preferred version of the board in
meta-yocto-bsp." -Bruce

Hope I have the necessary changes here.  I'm cc'ing the people who were
addressed in the previous uprev for rsp.  Apologies if that's too much.

---

I also noticed that the fix for 3514 needs to carry forward.  Sending
along a patch for that as well.  It probably won't happen again since
people tend to use the previous file version as template.

[PATCH] routerstationpro: move board off 3.4 and onto the 3.8 kernel

[michel.thebeau]

From: Michel Thebeau <michel.thebeau@windriver.com>

The updated patch series to support this target is in place on the BSP
specific branch in the 3.8 kernel tree now[1], so we can move it ahead
off of the old 3.4 kernel.

[PATCH] kernel 3.8: routerstationpro: use KERNEL_IMAGE_MAXSIZE to test the image

[michel.thebeau]

From: Michel Thebeau <michel.thebeau@windriver.com>

routerstationpro is limited to 16mb flash size.  Exceeding that size may
not be noticed immediately, which we don't want.

"The current latest kernel for the routerstationpro machine is far
beyond the 16MB of it's flash size [0]. I think it would be good to
[test if the size of the image is above that size]."

Setting this variable will enable the do_sizecheck task and produce an
error when the image is too large:

"ERROR: This kernel (size=90230265 > 16777216) is too big for your
device. Please reduce the size of the kernel by making more of it
modular."

Taken from commit 83716e40edacfd20dec8ef41f415ad5828d4643b.

Why would it need an _append_ ?
KERNEL_IMAGE_MAXSIZE_routerstationpro = "16777216" should be enough.

And by the way such kernel sizes look really exaggerated.

Thanks Andrea,

I'll drop _append_.

I'm not sure what you mean mean by exaggerated.  I multiplied 16mb with
2^20 == 16777216.

My comment was about the kernel sizes listed in the error msg:

 "ERROR: This kernel (size=90230265 > 16777216) is too big for your..."

Not knowing about the specific machine I can only guess this kernel is
embedding an initramfs for some specific purpose...but in my
experience I've never ever seen such huge sizes for a kernel.

Perplexed...

Hi Andrea,

poky commits cd2f003b512adf545dd3e5edd9aad68e09e9cda7 and
95b71d2b03a3a6dc5d32a7d6a84ec3420f39aa61 strip these sections from the
vmlinux elf image:
    .debug_aranges
    .debug_info
    .debug_abbrev
    .debug_line
    .debug_frame
    .debug_str
    .debug_loc
    .debug_ranges
    .symtab
    .strtab

The largest section remaining is .text
${CROSS_COMPILE}readelf -S vmlinux
...
  [ 1] .text             PROGBITS...	5823f0...
...

So the 90mb you are seeing is mostly .debug sections, which we removed
for bug 3515 - "The size of the kernel image is too big [to fit in flash]"

Thanks for getting back to me.  I'll resend the patches tomorrow.
