are you booting grub in BIOS or UEFI mode? GRUB in BIOS mode is
usually pretty slow because it constantly has to switch between real
and protected mode. In UEFI, GRUB is running at full speed.
Ofc, that doesn't help you if you need to boot in BIOS mode, but it's
a hint at where the slowness may co
ine data (not
> yet in GRUB upstream).
Can all the problems you've listed be detected? If so we can just deny
writing if a specific fs feature is enabled.

I mean safe in the sense that it would not destroy data outside of that
file (no matter if writing was successful or not) or even destroy/add
errors to the filesystem.(ext*, f2fs, fat*, ...).

Hi,
how safe is the usage of save_env? I'm considering writing like 100MB to a
loop file using the technique used by this command.
Thanks

couldn't we generate GUID's based on the current git revision?
this way you reproduce the ISO without even looking at the timestamp.
I don't know anything about the entropy requirements though. Lets wait for
a reply of the maintainers about that.

I found a bug in the 'grub_f2fs_read_file' function.
It fails when the file position is not 0. to fix it:
- grub_memcpy (buf + pos, inline_addr + pos, len);
+ grub_memcpy (buf, inline_addr + pos, len);

I think we should create a new loader(maybe separating common linux and
android code into a lib) for this rather than a filesystem because it would
simplify grub.cfg files.
Also in case we'll ever need to support 2ndloader(I'm like 99% sure this
will never happen though) it would be easier to imple

doesn't your device have any buttons(volume?) without the keyboad?
That would be way easier then adding touchscreen support especially if UEFI
doesn't provide a API for that(which I guess it doesn't).

Any ideas what could slow down the image scaling algorithm?
The only reasons I could think of would either be slow memory or some
compiler problems. Since my Ram is mapped cachable I don't think the
RAM is too slow.
I even forces using the Nearest neighbor algorithm already. It speeds
things up a
yea everyone uses either the master branch or the latest beta - it
should be pretty stable.
I guess there just isn't anyone who has the time to test every single
feature to find bugs so we can say it's 99% stable.

Hi,
when compiling grub with O2 or O3 on a ARM target mkimage fails with
"error: relocation4 X is not implemented yet" for

What's the best way to easily test non arch specific changes to GRUB?
The qemu tutorial usually are about booting linux and executing the grub
installer which is not what u want when u need to test changes very often.

It simplifies review a lot.

What I need is the partition name set in the GPT/MBR partition table.

Hi,
currently GRUB allows selecting partitions by the partition number only -
like (hd0,11).
Sometimes - especially for embedded systems it would be useful to be able
to select them by the name define in the partition table. like: (hd0,boot)
or (hd0,rootfs).
Are they any plans(or existing feature
