[PATCH] ppc64: Fix PER_LINUX32 behaviour

2005-06-08T23:24:15+00:00

This patch fixes some bugs in the ppc64 PER_LINUX32 implementation,
noted by Juergen Kreileder:

* uname(2) doesn't respect PER_LINUX32, it returns 'ppc64' instead of 'ppc'
* Child processes of a PER_LINUX32 process don't inherit PER_LINUX32

Along the way I took the opportunity to move things around so that
sys_ppc32.c only has 32-bit syscall emulation functions and to remove
the obsolete "fakeppc" command line option.

[PATCH] ppc64 kprobes: remove spurious MSR_SE masking

2005-06-08T23:21:13+00:00

Remove spurious MSR_SE reset during kprobe processing.
single_step_exception() already does it for us.  Reset it to be safe when
executing the fault_handler.

[PATCH] ppc64 kprobes: correct kprobe registration return values

Add stricter checks during kprobe registration.  Return correct error value so
insmod doesn't succeed.  Also printk reason for registration failure.

[PATCH] ppc64 kprobes: don't eat dabr/iabr exceptions

2005-06-08T17:18:59+00:00

Kprobes was eating the hardware instruction and data address
breakpoint exceptions.  This patch fixes it; kprobes doesn't use those
exceptions at all and should ignore them.

[PATCH] ppc64: print negative numbers correctly in boot wrapper

2005-06-08T17:18:59+00:00

if num has a value of -1, accessing the digits[] array will fail and the
format string will be printed in funny way, or not at all. This happens if
one prints negative numbers.
Just change the code to match lib/vsprintf.c
asm/div64.h cant be used because u64 maps to u32 for this build.

[PATCH] prom_find_machine_type typo breaks pSeries lpar boot

2005-06-03T20:20:04+00:00

A typo in prom_find_machine_type from Ben's recent patch "ppc64: Fix
result code handling in prom_init" prevents pSeries LPAR systems from
booting.

Tested on a pSeries 570 and OpenPower 720 (both Power5 LPAR).

[PATCH] ppc64: remove decr_overclock

2005-06-02T22:12:30+00:00

Now that we have HZ=1000 there is much less of a need for decr_overclock.
Remove it.

Leave spread_lpevents but move it into iSeries_setup.c.  We should look at
making event spreading the default some day.

[PATCH] ppc64: cleanup iseries runlight support

2005-06-02T22:12:30+00:00

The iseries has a bar graph on the front panel that shows how busy it is.
The operating system sets and clears a bit in the CTRL register to control
it.

Instead of going to the complexity of using a thread info bit, just set and
clear it in the idle loop.

Also create two helper functions, ppc64_runlatch_on and ppc64_runlatch_off.

Finally don't use the short form of the SPR defines.
