Hi All,
The existing BIOS-DUP's will not work on latest kernel, which has CONFIG_FW_LOADER_USER_HELPER=n ?configured in Kernel config by default which is not expected by the dell_rbu.
We have made a changes in BIOS-Dell Update Package so that BIOS-DUP will pick the payload from the /lib/firmware/ path & update the BIOS even when CONFIG_FW_LOADER_USER_HELPER=n is configured .
We have tested this patch http://www.spinics.net/lists/kernel/msg1755247.html?with latest BIOS Dell Update Package?(which has new implementation for the BIOS update i.e, copying the BIOS payload in /lib/firmware path & dell_rbu picks the payload from the same path) ?& with ?stable upstream ?????kernel-3.14.5 & we don't see any negative effects/errors for dell_rbu.
All the Test results are positive.
Regards
Balaji Singh

Thanks for testing! May I ask if the dell_rbu still works with my
patch and CONFIG_FW_LOADER_USER_HELPER=n with the old userspace? The
intention was that you should not need to change anything in userspace
at all.
By the way, there is now a new version of this patch:
<https://lkml.org/lkml/2014/6/4/327>, which should allow your (old or
new userspace) Dell RBU to work with FW_LOADER_USER_HELPER_FALLBACK=n,
so maybe it would be best to test that instead.
Cheers,
Tom
Hi Tom,
Older userspace or existing DUP's doesn't work with your patch & CONFIG_FW_LOADER_USER_HELPER=n.
I will give a try with https://lkml.org/lkml/2014/6/4/327 new patch & let you know ASAP.

Hi Tom,
I see contradiction of drivers/base/Kconfig here i.e, If I configure DELL_RBU=y I cannot configure FW_LOADER_USER_HELPER=n.
with this patch https://lkml.org/lkml/2014/6/4/327 i cannot have FW_LOADER_USER_HELPER=n & DELL_RBU=y at the same time.
I'm using the latest stable upstream kernel-3.14.5.
Symbol: FW_LOADER_USER_HELPER [=y]
Type : boolean
Defined at drivers/base/Kconfig:146
Selected by: FW_LOADER_USER_HELPER_FALLBACK [=n] && FW_LOADER [=y] || DELL_RBU [=y] && X86 [=y]

Yes, with that version of the patch you should instead try with
FW_LOADER_USER_HELPER_FALLBACK=n (the options were renamed). Does that
work for you?

None of these patches were in 3.15, so that should behave as before.
Cheers,
