  • 218a12f1f   microblaze: Don't mark arch_kgdb_ops as const. ... Browse Code »

    Other architectures don't do it, and it conflicts with the extern'd definition
    in include/linux/kgdb.h.

    The patch fails checkpatch but it reflects current
    functions declaration and solved compilation error.

  • 2d5973cb5   microblaze: Add KGDB support ... Browse Code »

    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.
