sh: Wire up oops reporting in the die notifier chain.

2008-10-21T09:33:36Z

Commit 3f5a54e371ca20b119b73704f6c01b71295c1714 ("ftrace: dump out ftrace buffers to console on panic") added an ftrace buffer dumper that hooks in to the die notifier chain and dumps out data in the oops path. Unfortunately SH supported ftrace but didn't support DIE_OOPS, so add that in and get it building again. Signed-off-by: Paul Mundt

sh: Move lookup_exception_vector() out to asm/system_32.h.

2008-09-21T03:00:23Z

There are other places where we want to have access to the trap/exception number, so move out the lookup_exception_vector() helper. While we're at it, refactor it slightly to return the vector instead. Signed-off-by: Paul Mundt

sh: Fix up fpu emu build.

The addition of the kprobes code pushed down a variable declaration, clean it up. Signed-off-by: Paul Mundt

sh: Add kprobes support.

2008-09-08T01:35:05Z

Initial support for kprobes/kretprobes for 32-bit SH platforms. [ General cleanup and some rework for the kretprobe hash lock. -- PFM ] Signed-off-by: Chris Smith Signed-off-by: Paul Mundt

sh: fixup many sparse errors.

sh2(A) exception handler update

2008-07-28T09:10:34Z

This patch is By sh2 - Remove duplicate code - Reduce stack usage - Cleanup and little optimize By sh2a - Add missing handler(256 to 511) - Use sh2a instructions handler Signed-off-by: Yoshinori Sato Signed-off-by: Paul Mundt

sh: trapped io support V2

2008-02-14T05:22:09Z

The idea is that we want to get rid of the in/out/readb/writeb callbacks from the machvec and replace that with simple inline read and write operations to memory. Fast and simple for most hardware devices (think pci). Some devices require special treatment though - like 16-bit only CF devices - so we need to have some method to hook in callbacks. This patch makes it possible to add a per-device trap generating filter. This way we can get maximum performance of sane hardware - which doesn't need this filter - and crappy hardware works but gets punished by a performance hit. V2 changes things around a bit and replaces io access callbacks with a simple minimum_bus_width value. In the future we can add stride as well. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: use opcode_t and enable unaligned code for sh2a

2008-02-14T05:22:09Z

This patch converts the unaligned access handling code to use opcode_t instead of u16. While at it, enable unaligned access handling for sh2a. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: add byte support to the sign extension code

2008-02-14T05:22:09Z

This patch adds byte support to the sign extension code. Unaligned access traps should never be generated on 8-bit io operations, but we will use this code for trapped io and we do need byte support there. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt
