microblaze: Do not use module.h in files which are not modules

2013-02-12T10:24:45Z

Based on the patch: "lib: reduce the use of module.h wherever possible" (sha1: 8bc3bcc93a2b4e47d5d410146f6546bca6171663) fix all microblaze files which are not modules. Signed-off-by: Michal Simek

microblaze: Raise SIGFPE/FPE_INTDIV for div by zero

2011-10-14T10:24:31Z

It fixes the signal nr raised for divizion by zero from SIGILL to SIGFPE, in accordance to POSIX and other archs. This came up due to a failed test in the GCC testsuite. Signed-off-by: Edgar E. Iglesias

microblaze: Fix sparse warning - sw_exceptions

2011-03-09T07:09:58Z

Function sw_exception is linked with asm code. Warning log: CHECK arch/microblaze/kernel/exceptions.c arch/microblaze/kernel/exceptions.c:53:6: warning: symbol 'sw_exception' was not declared. Should it be static? Signed-off-by: Michal Simek

microblaze: Clear i/dcache for sw breakpoints

2011-01-03T09:16:56Z

There is necessary to flush dcache and invalidate icache for address where breakpoint (brki r16, 0x18) was. The reason is that for some cases icache line still keeps brki instruction and it is not updated by origin instruction maintains by gdbserver. Signed-off-by: Michal Simek

microblaze: Remove old user debugging gdb stub

2010-10-21T05:51:23Z

Old gdb uses priviledged exception handler to handle gdb exception. New gdb uses brki r16, 0x18 that's why we can remove old gdb support. Signed-off-by: Michal Simek

microblaze: Add KGDB support

2010-08-04T08:45:17Z

Kgdb uses brki r16, 0x18 instruction to call low level _debug_exception function which save current state to pt_regs and call microblaze_kgdb_break function. _debug_exception should be called only from the kernel space. User space calling is not supported because user application debugging uses different handling. pt_regs_to_gdb_regs loads additional special registers which can't be changed * Enable KGDB in Kconfig * Remove ancient not-tested KGDB support * Remove ancient _debug_exception code from entry.S Only MMU KGDB support is supported.

microblaze: Support brki rX, 0x18 for user application debugging

2010-08-04T08:45:16Z

This is the first patch which add support for user application debugging through brki rX, 0x18 vector. This patch has side effect which also remove security issue to use brki rX, 0x18 to freeze kernel. Support for old gdb support via priviledged exception (brk r0, r0) is still there. It will be remove in future. Signed-off-by: Michal Simek
