config DEBUG_HWERR
bool "Hardware error interrupt debugging"
depends on DEBUG_KERNEL
help
When enabled, the hardware error interrupt is never disabled, and
will happen immediately when an error condition occurs. This comes
at a slight cost in code size, but is necessary if you are getting
hardware error interrupts and need to know where they are coming
from.
config DEBUG_ICACHE_CHECK
bool "Check Instruction cache coherency"
depends on DEBUG_KERNEL
depends on DEBUG_HWERR
help
Say Y here if you are getting weird unexplained errors. This will
ensure that icache is what SDRAM says it should be by doing a
byte wise comparison between SDRAM and instruction cache. This
also relocates the irq_panic() function to L1 memory, (which is
un-cached).
config DEBUG_HUNT_FOR_ZERO
bool "Catch NULL pointer reads/writes"
default y
help
Say Y here to catch reads/writes to anywhere in the memory range
from 0x0000 - 0x0FFF (the first 4k) of memory. This is useful in
catching common programming errors such as NULL pointer dereferences.
Misbehaving applications will be killed (generate a SEGV) while the
kernel will trigger a panic.
Enabling this option will take up an extra entry in CPLB table.
Otherwise, there is no extra overhead.
config DEBUG_BFIN_HWTRACE_ON
bool "Turn on Blackfin's Hardware Trace"
default y
help
All Blackfins include a Trace Unit which stores a history of the last
16 changes in program flow taken by the program sequencer. The history
allows the user to recreate the program sequencer’s recent path. This
can be handy when an application dies - we print out the execution
path of how it got to the offending instruction.
By turning this off, you may save a tiny amount of power.

prompt "Omit loop Tracing"
default DEBUG_BFIN_HWTRACE_COMPRESSION_OFF
depends on DEBUG_BFIN_HWTRACE_ON
help
The trace buffer can be configured to omit recording of changes in
program flow that match either the last entry or one of the last
two entries. Omitting one of these entries from the record prevents
the trace buffer from overflowing because of any sort of loop (for, do
while, etc) in the program.
Because zero-overhead Hardware loops are not recorded in the trace buffer,
this feature can be used to prevent trace overflow from loops that
are nested four deep.

help
By selecting this option, every time the 16 hardware entries in
the Blackfin's HW Trace buffer are full, the kernel will move them
into a software buffer, for dumping when there is an issue. This
has a great impact on performance, (an interrupt every 16 change of
flows) and should normally be turned off, except in those nasty
debugging sessions

config DEBUG_BFIN_NO_KERN_HWTRACE
bool "Trace user apps (turn off hwtrace in kernel)"
depends on DEBUG_BFIN_HWTRACE_ON
default n
help
Some pieces of the kernel contain a lot of flow changes which can
quickly fill up the hardware trace buffer. When debugging crashes,
the hardware trace may indicate that the problem lies in kernel
space when in reality an application is buggy.
Say Y here to disable hardware tracing in some known "jumpy" pieces
of code so that the trace buffer will extend further back.
config EARLY_PRINTK
bool "Early printk"
default n
help
This option enables special console drivers which allow the kernel
to print messages very early in the bootup process.
This is useful for kernel debugging when your machine crashes very
early before the console code is initialized. After enabling this
feature, you must add "earlyprintk=serial,uart0,57600" to the
command line (bootargs). It is safe to say Y here in all cases, as
all of this lives in the init section and is thrown away after the
kernel boots completely.
