Hi,
On EFI platform, every partition is regarded as one block device and
responding EFI device path. EFI device patch has the same hierarchical
relationship with the partition. This patch will search root EFI device
path by current device patch, but not parent device path.
Original grub can not find efi disk when grub.efi is executed on
logical partition.
Previously I posted this patch, now I repost again.
Any suggestion is welcome.
thanks
bibo,mao

This code can be shorter; you only have to compare the lengths. If
they match, you can do a memcmp on the whole device path.
Also, can you guarantee that the child path "dp2" is longer than the
parent path? What it does is that it checks if "parent" is a subpath
of "dp2", so a function name reflecting that probably fits better.
Name functions after what they do, not what they are used to. Better
argument names are also welcome.

It could look something like this;
/* Returns zero if device path SUBPATH is a subpath of device path
PATH. */
static int
compare_subpath (const grub_efi_device_path_t *subpath,
const grub_efi_device_path_t *path)
{
if (! subpath || ! path)
return 1;
while (1)
{
int len, ret;
if (GRUB_EFI_END_ENTIRE_DEVICE_PATH (subpath))
return 0;
else if (GRUB_EFI_END_ENTIRE_DEVICE_PATH (path))
return 1;
if (GRUB_EFI_DEVICE_PATH_LENGTH (subpath)
!= GRUB_EFI_DEVICE_PATH_LENGTH (path))
return ((int) GRUB_EFI_DEVICE_PATH_LENGTH (subpath)
- (int) GRUB_EFI_DEVICE_PATH_LENGTH (path));
len = GRUB_EFI_DEVICE_PATH_LENGTH (path);
ret = grub_memcmp (subpath, path, len);
if (ret)
return ret;
path = (grub_efi_device_path_t *) ((char *) path + len);
subpath = (grub_efi_device_path_t *) ((char *) subpath + len);
}
}
I guess that should work at least, it is not tested.
In gnufi I have a device_path_iterate function that could be used for
these kind of things. Maybe we should bring it in to GRUB2.
/* Iterate nodes of the device path. *PATHP should be set to point to
the path that is to be iterated. NULL will be returned when the
end of the path has been reached. */
efi_device_path_t *
efi_device_path_iterate (efi_device_path_t **pathp)
{
efi_device_path_t *p = *pathp;
if (EFI_END_ENTIRE_DEVICE_PATH (p))
return NULL;
else
{
efi_uint_t len = EFI_DEVICE_PATH_LENGTH (p);
*pathp = (efi_device_path_t *) (((char *) p) + len);
return p;
}

I tested on my EFI IA32 bios, it works for me, your method is better
than me, I incorporated your function in my second patch.
