powerpc/perf: e500 support

2010-03-05T09:04:08Z

This implements perf_event support for the Freescale embedded performance monitor, based on the existing perf_event.c that supports server/classic chips. Some limitations: - Performance monitor interrupts are regular EE interrupts, and thus you can't profile places with interrupts disabled. We may want to implement soft IRQ-disabling, with perfmon interrupts exempted and treated as NMIs. - When trying to schedule multiple event groups at once, and using restricted events, situations could arise where scheduling fails even though it would be possible. Consider three groups, each with two events. One group has restricted events, the others don't. The two non-restricted groups are scheduled, then one is removed, which happens to occupy the two counters that can't do restricted events. The remaining non-restricted group will not be moved to the non-restricted-capable counters to make room if the restricted group tries to be scheduled.

powerpc: broadway processor support

2009-12-13T05:24:29Z

This patch extends the cputable entry of the 750CL to also match the 750CL-based "Broadway" cpu found on the Nintendo Wii. As of this patch, the following "Broadway" design revision levels have been seen in the wild: - DD1.2 (87102) - DD2.0 (87200) Signed-off-by: Albert Herranz Acked-by: Benjamin Herrenschmidt Signed-off-by: Grant Likely

powerpc/oprofile: Add ppc750 CL as supported by oprofile

Here's a patch that adds the ppc750 CL cpu as supported by oprofile. Signed-off-by: Dragos Tatulea Signed-off-by: Benjamin Herrenschmidt

powerpc/book3e-64: Move the default cpu table entry

2009-08-28T04:24:13Z

Move the default cpu entry table for CONFIG_PPC_BOOK3E_64 to the very end since we will probably want to support both 32-bit and 64-bit kernels for some processors that are higher up in the list. Signed-off-by: Kumar Gala Signed-off-by: Benjamin Herrenschmidt

powerpc: Remaining 64-bit Book3E support

2009-08-20T00:25:11Z

This contains all the bits that didn't fit in previous patches :-) This includes the actual exception handlers assembly, the changes to the kernel entry, other misc bits and wiring it all up in Kconfig. Signed-off-by: Benjamin Herrenschmidt

powerpc: Add 2.06 tlbie mnemonics

2009-05-21T05:44:21Z

This adds the PowerPC 2.06 tlbie mnemonics and keeps backwards compatibilty for CPUs before 2.06. Only useful for bare metal systems. Signed-off-by: Milton Miller Signed-off-by: Michael Neuling Signed-off-by: Benjamin Herrenschmidt

powerpc/pseries: Really fix the oprofile CPU type on pseries

2009-05-15T06:43:42Z

My previous pach for fixing the oprofile CPU type got somewhat mismerged (by my fault) when it collided with another related patch. This should finally (fingers crossed) fix the whole thing. We make sure we keep the -old- oprofile type and CPU type whenever one of them was specified in the first pass through the function. Signed-off-by: Benjamin Herrenschmidt

powerpc: Fix setting of oprofile cpu type

2009-05-01T05:12:05Z

commit 2657dd4e301d4841ed67a4fac7d145ad8f3e1b28 introduced a bug where we would now always override the "real" oprofile CPU type with the "compatible" one provided by a pseudo-PVR in the device-tree which is incorrect and breaks oprofile on all current configs since the "compatible" ones aren't yet recognized. This fixes it. Signed-off-by: Benjamin Herrenschmidt

powerpc adjust oprofile_cpu_type version 3

2009-05-01T05:12:05Z

Oprofile is changing the naming it is using for the compatibility modes. Instead of having compat-power, oprofile will go to family naming convention and use ibm-compat-v. Currently only ibm-compat-v1 will be defined. The notion of compatibility events just started with POWER6. So there is no way that any other tool could exist that is using these oprofile_cpu_type strings we want to change. Signed-off-by: Mike Wolf Signed-off-by: Benjamin Herrenschmidt
