-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.
-
-config DEBUG_BFIN_HWTRACE_COMPRESSION_OFF
- bool "Trace all Loops"
- help
- The trace buffer records all changes of flow
-
-config DEBUG_BFIN_HWTRACE_COMPRESSION_ONE
- bool "Compress single-level loops"
- help
- The trace buffer does not record single loops - helpful if trace
- is spinning on a while or do loop.
-
-config DEBUG_BFIN_HWTRACE_COMPRESSION_TWO
- bool "Compress two-level loops"
- help
- The trace buffer does not record loops two levels deep. Helpful if
- the trace is spinning in a nested loop

-config DEBUG_BFIN_HWTRACE_EXPAND
- bool "Expand Trace Buffer greater than 16 entries"
- depends on DEBUG_BFIN_HWTRACE_ON
- default n
- 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_HWTRACE_EXPAND_LEN
- int "Size of Trace buffer (in power of 2k)"
- range 0 4
- depends on DEBUG_BFIN_HWTRACE_EXPAND
- default 1
- help
- This sets the size of the software buffer that the trace information
- is kept in.
- 0 for (2^0) 1k, or 256 entries,
- 1 for (2^1) 2k, or 512 entries,
- 2 for (2^2) 4k, or 1024 entries,
- 3 for (2^3) 8k, or 2048 entries,
- 4 for (2^4) 16k, or 4096 entries
-
-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.
-
-config DUAL_CORE_TEST_MODULE
- tristate "Dual Core Test Module"
- depends on (BF561)
- default n
- help
- Say Y here to build-in dual core test module for dual core test.
-
-config CPLB_INFO
- bool "Display the CPLB information"
- help
- Display the CPLB information.
-
-config ACCESS_CHECK
- bool "Check the user pointer address"
- default y
- help
- Usually the pointer transfer from user space is checked to see if its
- address is in the kernel space.
-
- Say N here to disable that check to improve the performance.
