I'm sending this out as a RFC to get feedback and see which way folks would
like to go. Patch 1 of this patch set makes COMMAND_LINE_SIZE a seperate
config option for each architecture. However, an alternative to that would be
to create a single default size(Possibly 2048 to satisfy patchs 2 and 3 of this
patch set) for COMMAND_LINE_SIZE in ~kernel/Kconfig or ~init/Kconfig and then
allow the different architecures to either bump this size up or down if needed.
This set of changes focus on COMMAND_LINE_SIZE. An inital patch was created to
increase the size of COMMAND_LINE_SIZE for the powerpc architecture. However,
after looking at the code, it appears powerpc does not actually use the define
in the ppc headers but uses the common generic default. It seems like having
COMMAND_LINE_SIZE a kernel config options is a cleaner way to modify the value,
instead of going through and chaning defines. This applies to all
architectures and not just powerpc.
The powerpc architecture uses asm-generic to set the value of
COMMAND_LINE_SIZE, which should be changed to a kernel config option.
The size of COMMAND_LINE_SIZE for powerpc should be longer than 512 characters,
as iscsi targets and cloud-init parameters are passed through the kernel
command line.
Joseph Salisbury (3):
kconfig: Change COMMAND_LINE_SIZE to a kernel config option, which is
now set per architecture.
powerpc: Change the powerpc architecture to use Kconfig to set
COMMAND_LINE_SIZE.
powerpc: kconfig: Increase the size of COMMAND_LINE_SIZE to 2048 from
512 for powerpc.
