is the -mabi=no-spe really needed?
It seems to work the other way around (without -mabi=no-spe but
with
-mabi=no-spe) alteast I did not find anything in do_syslog() or
while
browsing through the dissasm. I do a boot check tomorrow.
Okay. I recompiled with -mspe=no and was able to boot without
trouble.
It didn't work with -mabi=no-spe.
I'm confused.. what did you change from your patch?
This is the patch it right now:
--- a/arch/powerpc/Makefile
+++ b/arch/powerpc/Makefile
@@ -103,6 +103,7 @@ KBUILD_CFLAGS += $(call cc-option,-mno-altivec)
# No SPE instruction when building kernel
KBUILD_CFLAGS += $(call cc-option,-mno-spe)
+KBUILD_CFLAGS += $(call cc-option,-mspe=no)
# Enable unit-at-a-time mode when possible. It shrinks the
# kernel considerably.
--
With this patch it compiles and boots fine.
The option -mabi=no-spe is not required.
ok. can post a clean patch w/just this change.
