On PCXS chips (PA7000, pa 1.1a), trap #18 is raised on memory faults, while all later chips (>= PA7100) generate either trap #26, #27 or #28 (depending on the fault type). Since the current qemu emulation emulates a B160L machine (with a PA7300LC PCX-L2 chip, we should raise trap #26 (EXCP_DMAR) instead of #18 (EXCP_DMP) on access faults by the Linux kernel to page zero. With the patch we now get the correct output (I tested against real hardware): Kernel Fault: Code=26 (Data memory access rights trap) instead of: Kernel Fault: Code=18 (Data memory protection/unaligned access trap) Signed-off-by: Helge Deller <deller@gmx.de> Message-Id: <20181007205153.GA30270@ls3530.fritz.box> Signed-off-by: Richard Henderson <richard.henderson@linaro.org> |
