From e2fdd7fd99dd68b77caaf2a2272b75b5da890de7 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 29 Apr 2008 02:38:50 -0700 Subject: sparc: Add kgdb support. Current limitations: 1) On SMP single stepping has some fundamental issues, shared with other sw single-step architectures such as mips and arm. 2) On 32-bit sparc we don't support SMP kgdb yet. That requires some reworking of the IPI mechanisms and infrastructure on that platform. Signed-off-by: David S.
