We currently do not. Also make it easier to handle cplb violations - in traps.c Signed-off-by:

- move the CONFIG_KGDB into one block, for easier reading - remove printk from printk_address, and pass around buffers. Also print out the labels when decoding CPLB errors, so you know exactly where the error was. - Do not use fixed addresses, becuase people do not know where they come from. - Turn the printing level down on the dump, so if you don't want, only the signal prints out - just like on other archs. If a kernel/interrupt crashes, it should dump everything all the time Signed-off-by:

This fixes two things: - stop calling write_lock_irq/write_unlock_irq which can turn modify irq levels - don't calling mmput when handing exceptions - since this might_sleep, which does a rti, and leaves us in kernel space (irq15, rather than irq5). Signed-off-by:

We must balance calls to get_task_mm with corresponding mmput calls, otherwise refcounting is screwed up and mms don't get freed when their task exits. Signed-off-by:

Blackfin arch: Enable earlyprintk earlier - so any error after our interrupt tables are set up will print out Also ensure that the traps_c code doesn't cause a double fault, by sending a signal to a faulting kernel before the memory subsystem is fully initialized, by printing out the error message before sending the signal.

Today when a double fault happens (exception during an exception handling event), we go into an endless loop, with nothing comming out the UART. With this patch, we actually see that we have commited a double fault event Signed-off-by:

add an exception request/free api similar to the interrupt request/fre api so people can utilize the free software based exceptions for their own purposes Signed-off-by:

Add ability to expend the hardware trace buffer via a configurable software buffer - so you can have lots of history when a crash occurs. The interesting way we do printk in the traps.c confusese the checking script Signed-off-by:

Turns on trace earlier, so crashes at kernel start should print out a trace, making things easier to debug. Signed-off-by:

This adds support for the Analog Devices Blackfin processor architecture, and currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561 (Dual Core) devices, with a variety of development platforms including those avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP, BF561-EZKIT), and Bluetechnix! Tinyboards. The Blackfin architecture was jointly developed by Intel and Analog Devices Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in December of 2000. Since then ADI has put this core into its Blackfin processor family of devices. The Blackfin core has the advantages of a clean, orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC (Multiply/Accumulate), state-of-the-art signal processing engine and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The Blackfin architecture, including the instruction set, is described by the ADSP-BF53x/BF56x Blackfin Processor Programming Reference http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf The Blackfin processor is already supported by major releases of gcc, and there are binary and source rpms/tarballs for many architectures at: http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete documentation, including "getting started" guides available at: http://docs.blackfin.uclinux.org/ which provides links to the sources and patches you will need in order to set up a cross-compiling environment for bfin-linux-uclibc This patch, as well as the other patches (toolchain, distribution, uClibc) are actively supported by Analog Devices Inc, at: http://blackfin.uclinux.org/ We have tested this on LTP, and our test plan (including pass/fails) can be found at: http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel [m.kozlowski@tuxland.pl: balance parenthesis in blackfin header files] Signed-off-by:
