Using grub on fuloong 6004

Using grub on fuloong 6004

[David Kuehling]

[-- Attachment #1: Type: text/plain, Size: 1421 bytes --]

Hi,

I've been unsuccessful so far with making grub work on my Fuloong 6004
box.  What I tried first wast the 'grub-yeeloong' package of debian
squeeze, building a grub.elf as described in the debian-yeeloong wiki
[1] (i.e. grub-mkimage --format=mipsel-yeeloong-elf ...)

The resulting grub.elf only shows a black screen when loaded from pmon,
and doesn't show any reactions.

Then I found some mailinglist threads that refer to
--format=mipsel-fuloong-elf (i.e. not "yeeloong").  Only the bzr trunk
seems to have support for that.  Tried this thursday's trunk version,
and built my image using

  sudo grub-mkimage  --config=/boot/grub.elf.conf \
     --output=/boot/grub3.elf --format=mipsel-fuloong-elf --verbose \
      ata part_msdos ext2 reboot halt lspci ohci usbtest usbms linux \
      fat xfs part_gpt multiboot2 minicmd configfile gcry_md5 hashsum

My /boot/grub.elf.conf reads

  set root=ata0,msdos1
  set prefix=($root)/grub

My /boot partition is /dev/sda (ext3).

however, this image now blanks the screen and shortly after reboots the
fuloong when loaded from the pmon menu.

Am I doing anything wrong?  Is Fuloong support known to be not (fully)
functional?

cheers,

David

Fuloong 2F support was fully functional when it was merged. It's
possible though that there was a recent regression. I'll retest today.

Just recreated my grub.elf with ata in the grub.elf.conf replaced by
pata, plus 'pata' module added to the grub-mkimage command line.

Now the grub blanks the screen and hangs when loaded from pmon.

Maybe I should add that I'm using a 750GB hard-disk with 4k sectors in
my Fuloong.  Could that be a problem?  It's neigher a problem for pmon
nor for linux, though.

cheers,

David

There is a regression between r3284 and r3384. Bisecting it.

I have no such disk. We have support for 4K-sector disks but I'm not
sure if it works with our ATA but if it doesn't it's trivial to fix.
Just regressions first.

I'm attaching a patch which should add the support for 4K sectors with ATA.

Ok, I tried the new trunk, once with your patch and once without it.

Now grub comes up and displays a prompt, but not a menu.  Keyboard
doesn't work however, so I cannot do anything with grub yet.

I tried to re-run grub-mkimage with module 'usb_keyboard' and 'ahci'
added, but that didn't help, keyboard still not working:

sudo grub-mkimage --config=/boot/grub.elf.conf
--output=/boot/grub4-4k.elf --format=mipsel-fuloong-elf --verbose ata
pata part_msdos ext2 reboot halt lspci ohci ahci usbtest usbms linux fat
xfs part_gpt multiboot2 minicmd configfile gcry_md5 hashsum usb_keyboard

grub.elf.conf:

set root=pata0,msdos1
set prefix=($root)/grub

I also ran 'grub-install' once, which put a full set of grub modules to
/boot/grub.  However, it failed to generate a grub image and complained:

$ sudo /usr/local/sbin/grub-install 
/usr/local/bin/grub-mkimage: error: cannot stat /usr/local/lib/grub/mipsel-loongson/uhci.mod.

according to lsusb, my keyboard is a

Bus 002 Device 003: ID 0b51:0020 Comfort Keyboard Co. Comfort Keyboard

, connected to the top-right usb slot.  Other than that only a usb-mouse
is also connected.  No hubs or other advanced usb-hardware.

Any ideas what's wrong now?

cheers,

David

usb_keyboard was obviously missing so I thought you use serial. Fuloong
neither uses nor implements AHCI.

Only module was renamed. Not the names of disks. You can achieve same
result much more easily with -p '(ata0,msdos1)/grub'

Can you try w/o mouse? Can you try with hotplugging keyboard rather than
having one on boot?

Ok, with your latest uhci.diff, I can now just run 'grub-install' which
leaves a (somewhat) working grub.elf in /boot.  Feels like we're getting
closer.

This shows the same behaviour like the grub-diy.elf that I generated via
grub-mkimage:

  - keyoard still not working.  Tried plugging in after grub startup,
  but doesn't help (for grub-diy.elf i had to shortly plug in the
  keyboard to select it in pmon, so mayb that doesn't count).  Also
  mouse was disconnected.

  - menu looks a little grabled (lots of '@' instead of border), but
  won't complain about that

Grub is already better working than Pmon.  Pmon refuses to load some of
my kernels without any indication why (seems to have problems depending
on image size, sometimes only vmlinux works, vmlinuz doesn't, kernels
compiled with -O2 don't work at all, need -Os etc.).

As far as I could test (without keyboard), grub now loads 3
kernels+initrd images that pmon would not load.

cheers,

David

If I use your grub.elf, it just prints something like 'Press Esc to skip
loading grub.cfg from hard-disk', then waits a few seconds, then the
screen gets black and the hdd led light flickers and it's trying to boot
something without success.  Pressing Esc on the keyboard doesn not have
any observable effect.

I tried with 4 different keyboards with no success.  

With my own grub.elf, adding debug=usb,ohci to my /boot/grub/grub.cfg
does not produce any output, but maybe it's just hidden by the menu
showing up?  Anything that I can do to be sure to see messages?
Redirect them to the serial port?

Just to be sure, I now updated my grub.cfg to contain

  insmod ohci
  insmod usb
  insmod usb_keyboard
  [..]
  terminal_input usb_keyboard

Which was generated from usr/local/etc/default/grub via the lines

  GRUB_TERMINAL_INPUT=usb_keyboard
  GRUB_PRELOAD_MODULES="ohci usb usb_keyboard"

The debug= lines I added before insmod ohci (but of course it's gone
after update-grub).

In case it is of any help, I attach 'lspci -vv' and 'lsusb -vv' output.

Yeah, with my dm-crypt partitions, grub has no chance to access its
fonts.  Moved them to /boot and added 

  GRUB_FONT=/boot/grub/fonts/euro.pf2

to my default/grub, now that part is fixed (I wonder why you don't copy
fonts to /boot when you detect partitions unaccessible to grub in
00_header.  debian's grub.d/05_debian_theme applies such a handling to
the splash images, copying them if neccessary).

BTW the device.map file is still misgenerated by grub-mkdevmap on
loongson.  It writes 'hd0' where it should use 'ata0'.

cheers,

David

That's because you have a separate /boot and the version I uploaded
looks only for /boot/grub/grub.cfg, not /grub/grub.cfg and in case of
failure it retries. So other than keyboard not working it works as expected.

That's weird given that code works with several keyboards here and also
on yeeloong.

Seems to be same as mine other than keyboard model, of course. In short,
