Next: [RFC PATCH 1/2] hw-breakpoints: Separate constraint space for data and instruction breakpoints
From: Frederic Weisbecker on 12 Apr 2010 19:30 Hi, These patches tend to extend the breakpoint allocation constraints to be more non-x86 friendly. It can separate the data and instruction breakpoint space and handle address ranges or other kind of tricky things that makes a breakpoint use more than one address register. There is still one kind of constraint it can't handle, something I've found on ARMv7 implementation: linking an breakpoint to a watchpoint. But if this needs arises, I will be glad to add that support. Beware, it's only compile-tested for now. Tell me what you think. Thanks.
