Early debug output for PA Semi UART. Uses the 2.05 CI real mode ops. Signed-off-by: Olof Johansson Signed-off-by: Paul Mackerras

[POWERPC] Celleb: basic support

This patch adds base support for Celleb platform. Signed-off-by: Kou Ishizaki Acked-by: Arnd Bergmann Acked-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] Enable stack debug features on ppc32

2007-01-30T06:45:56Z

Enable stack overflow checking (DEBUG_STACKOVERFLOW) and stack usage (DEBUG_STACK_USAGE) on ppc32. Signed-off-by: Kumar Gala

[POWERPC] Allow CONFIG_BOOTX_TEXT on iSeries

2006-12-04T09:41:58Z

and therefore combined builds. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[POWERPC] Allow xmon to build on legacy iSeries

2006-12-04T09:41:56Z

xmon still does not run on iSeries, but this allows us to build a combined kernel that includes it. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[POWERPC] Make xmon disassembly optional

2006-12-04T09:40:32Z

While adding spu disassembly support it struck me that we're actually carrying quite a lot of code around, just to do disassembly in the case of a crash. While on large systems it's not an issue, on smaller ones it might be nice to have xmon - but without the weight of the disassembly support. For a Cell build this saves ~230KB (!), and for pSeries ~195KB. We still support the 'di' and 'sdi' commands, however they just dump the instruction in hex. Move the definitions into a header to clean xmon.c just a tiny bit. Signed-off-by: Michael Ellerman Signed-off-by: Arnd Bergmann

[POWERPC] print backtrace when entering xmon

2006-09-13T08:39:53Z

xmon does not print a backtrace per default. This is bad on systems with USB keyboard, the most needed info about the crash is lost. print a backtrace during the very first xmon entry. Booting with xmon=nobt disables the autobacktrace functionality. Signed-off-by: Olaf Hering Signed-off-by: Paul Mackerras

[POWERPC] powerpc: Instrument Hypervisor Calls

2006-09-13T08:39:53Z

Add instrumentation for hypervisor calls on pseries. Call statistics include number of calls, wall time and cpu cycles (if available) and are made available via debugfs. Instrumentation code is behind the HCALL_STATS config option and has no impact if not enabled. Signed-off-by: Mike Kravetz Signed-off-by: Paul Mackerras

[POWERPC] Add udbg support for RTAS console

2006-06-28T01:59:48Z

Add udbg hooks for the RTAS console, based on the RTAS put-term-char and get-term-char calls. Along with my previous patches, this should enable debugging as soon as early_init_dt_scan_rtas() is called. Signed-off-by: Michael Ellerman Signed-off-by: Paul Mackerras

[PATCH] powerpc: Make early debugging options behave with oldconfig

2006-05-19T04:35:23Z

If you undefine all the early debugging options and then run make oldconfig, you don't get prompted to see if you want to enable any of them. This is annoying. AFAICT we can't do this just with a choice, because the choice is either optional, in which case we don't get prompted, or not in which case we _must_ select early debugging. So add a bool which controls whether we have early debugging at all, and then if that's enabled provide the choice. The extra bool will actually be useful in another patch I have lying around, so this is a win-win. Signed-off-by: Michael Ellerman Signed-off-by: Paul Mackerras
