linux-toradex.git/arch/m68knommu, branch v2.6.16.62 Linux kernel for Apalis and Colibri modules [PATCH] hrtimer: round up relative start time on low-res arches 2006-02-15T00:09:35+00:00 Ingo Molnar mingo@elte.hu 2006-02-14T21:53:15+00:00 06027bdd278a32a84b273e41db68a5db8ffd2bb6 CONFIG_TIME_LOW_RES is a temporary way for architectures to signal that they simply return xtime in do_gettimeoffset(). In this corner-case we want to round up by resolution when starting a relative timer, to avoid short timeouts. This will go away with the GTOD framework.

[PATCH] m68knommu: fix a5 reg corruption in signal handlers 2006-01-10T17:31:26+00:00 Greg Ungerer gerg@snapgear.com 2006-01-10T06:42:59+00:00 01829e7212dd9ba3fa68bf8afffc9a175c44cb04 This is a patch adapted from a posting by Andrea Tarani which was pointed out to me by Bernardo Innocenti. Thanks to both of them for their help and patience. The original posting is here: http://mailman.uclinux.org/pipermail/uclinux-dev/2005-July/033543.html The problem first manifest itself as busybox ping terminating with an "Illegal instruction". I reduced this to a test case and found that variable size arrays allocated on the stack could lead to stacks not aligned on 32 bit boundaries. For the Coldfire this proved fatal. Having been pointed out this patch by Bernardo, I applied it and it fixed the first test case. I then went back to busybox's ping. This still failed with "Illegal instruction", but in a different way. Before it depended on the size allocated for the ping buffer, now it happened every time. I also found it depended on optimisation level (gcc-3.4.0) -Os was okay but not -O2. After a lot of looking, it turned out that register a5 was being corrupted by the signal handler (after applying the patch). I re-worked the patch a bit to save/restore a5 and now all seems well.

still failed with "Illegal instruction", but in a different way.  Before

-Os was okay but not -O2.

After a lot of looking, it turned out that register a5 was being
corrupted by the signal handler (after applying the patch).  I re-worked
