From 4352fc1b12fae4c753a063a2f162ddf9277af774 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 5 Jan 2010 19:06:45 +0900 Subject: sh: Abstracted SH-4A UBC support on hw-breakpoint core. This is the next big chunk of hw_breakpoint support. This decouples the SH-4A support from the core and moves it out in to its own stub, following many of the conventions established with the perf events layering. In addition to extending SH-4A support to encapsulate the remainder of the UBC channels, clock framework support for handling the UBC interface clock is added as well, allowing for dynamic clock gating. This also fixes up a regression introduced by the SIGTRAP handling that broke the ksym_tracer, to the extent that the current support works well with all of the ksym_tracer/ptrace/kgdb. The kprobes singlestep code will follow in turn. With this in place, the remaining UBC variants (SH-2A and SH-4) can now be trivially plugged in.
