Hi, mengqian & all
Sorry for my late response.
Based on the previous work of Arnaud Patard[1] and Yajin[2], just
finished a basic 2.6.37 support(pci, irq, reset, video) for Gdium and
pushed it into our master branch[3], two default config files has been
added:
arch/mips/configs/gdium_{minimal,small}_defconfig
The minimal one is prepared for the rescue/recover system, the small
one can be used for desktop or development.
With anyone of the above config files, the kernel is bootable, the
later enabled more supports(wireless), if you need more drivers,
please refer to arch/mips/configs/lemote2f_defconfig.
To boot the kernel, you may need to install the modules into the
board's /lib/modules and copy the vmlinuz or vmlinux to the board's
/boot, and then, config the pmon(bootloader) environment variables and
boot with the new kernel:
1. Enter into the PMON commandline
power on your board, and press the 'C' key till you get the following prompt.
PMON>
2. Set the path to the kernel image in the "al" environment variable
// take a look at the existing environment variables
PMON> env
// or take a look at an indicated environment variable: al
PMON> env al
// backup the old al
PMON> set old_al $al
// set the new al, assume your kernel image(vmlinuz-2.6.37) is put at
the 2nd partition of your usb storage
PMON> set al /dev/fs/e...@usbg0/boot/vmlinuz-2.6.37
3. Set the kernel command line parameters in "karg"
PMON> env karg
PMON> set old_karg $karg
// Assume your root filesystem is at the 2nd partition of your usb storage
PMON> set kargs "console=tty1 root=/dev/sda2 rootwait init=/sbin/finit-mdv"
4. Load & Boot
// Load the kernel image
PMON> load $al
// Boot it
PMON> g $karg
If you want to load a kernel image from the tftp server, please enable
the network connection via the bootloader at first.
PMON> devls
...
rtl0
PMON> set ifconfig rtl0:<local_ip_addresss> // for example: set
ifconfig rtl0:192.168.0.131
PMON> load tftp://<tftp_server_ip_address>/path/to/tftpboot/vmlinuz
....
To get more information about gdium, PMON and the available systems on
it, please refer to [4].
More efforts are needed to forward-port the following supports from
2.6.29[3] to 2.6.37:
The EC support(hotkey, battery ...) from
drivers/platform/mips/gdium-laptop.c (seems no big change)
The sm501 based sound support from sound/soc/sm501 (may need enough
effort for the mainline has changed a lot)
The pm support(mainly "suspend to RAM") from
arch/mips/lemote/lm2f/*pm* (stl2_suspend2.patch, this may be hard too
but should be easy for basic pm support, the Hibernation should be
usable currently.)
Currently, I have no schedule to work on them, but I hope they may be
available one by one in the coming 3 ~ 6 weeks, which means 2.6.37 in
our linux-loongson-community git repository.
Best Regards,
Wu Zhangjin
