The commit 2111667b46 ("ARM: pxa: call debug_ll_io_init for
earlyprintk") triggers in the current kernel the attached backtrace on
PXA/tosa early in the boot time when DEBUG_LL is enabled.
It is due to overlap between uart virtual memory defined in
DEBUG_UART_VIRT and mapped by debug_ll_io_init() and peripheral bus
mapped by pxa_map_io at the same address, 0xf2100000.
As hinted by Arnd, map early virtual memory for low level debug on
address 0xf6200000, even if that means 2 virtual mappings will give
access to the pxa internal UARTs (FFUART, BTUART, STUART, ...).

When a user program crashes due to an exception, the kernel can

print a brief message explaining what the problem was. This is

sometimes helpful for debugging but serves no purpose on a

production system. Most people should say N here.

In addition, you need to pass user_debug=N on the kernel command
|
|
line to enable this feature. N consists of the sum of:
|
|
|
|
1 - undefined instruction events
|
|
2 - system calls

4 - invalid data aborts

8 - SIGSEGV faults

above. This relies on your platform choosing the right UART

help

Say Y here if you want the debug print routines to direct

their output to the EmbeddedICE macrocell's DCC channel using
|
|
co-processor 14. This is known to work on the ARM9 style ICE
|
|
channel and on the XScale with the PEEDI.
|

Note that the system will appear to hang during boot if there

is nothing connected to read from the DCC.

bool "Kernel low-level debug output via semihosting I/O"
|
|
help
|
|
Semihosting enables code running on an ARM target to use
|
|
the I/O facilities on a host debugger/emulator through a
|
|
simple SVC call. The host debugger or emulator must have
|
|
semihosting enabled for the special svc call to be trapped
|
|
otherwise the kernel will crash.
|
|
|
|
This is known to work with OpenOCD, as well as
|
|
ARM's Fast Models, or any other controlling environment
|
|
that implements semihosting.
|
|
|
|
For more details about semihosting, please see

Enabling this option causes the kernel to write the current PID to
|
|
the PROCID field of the CONTEXTIDR register, at the expense of some
|
|
additional instructions during context switch. Say Y here only if you
|

are planning to use hardware trace tools with this kernel.

---help---
|
|
This option helps catch unintended modifications to loadable
|
|
kernel module's text and read-only data. It also prevents execution
|
|
of module data. Such protection may interfere with run-time code
|
|
patching and dynamic kernel tracing - and they might also protect
|
|
against certain classes of kernel exploits.
|
|
If in doubt, say "N".
