* powerpc/40x: Distinguish AMCC PowerPC 405EX and 405EXr correctlyLee Nipper2010-07-261-7/+111
| | | | | | | | | | | | | | | | | | The recent AMCC 405EX Rev D without Security uses a PVR value that matches the old 405EXr Rev A/B with Security. The 405EX Rev D without Security would be shown incorrectly as an 405EXr. The pvr_mask of 0xffff0004 is no longer sufficient to distinguish the 405EX from 405EXr. This patch replaces 2 entries in the cpu_specs table and adds 8 more, each using pvr_mask of 0xffff000f and appropriate pvr_value to distinguish the AMCC PowerPC 405EX and 405EXr instances. The cpu_name for these entries now includes the Rev, in similar fashion to the 440GX. Signed-off-by: Lee Nipper <lee.nipper@gmail.com> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
* powerpc/e500mc: Implement machine check handler.Scott Wood2010-05-211-1/+1
| | | | | | | | | | | Most of the MSCR bit assigments are different in e500mc versus e500, and they are now write-one-to-clear. Some e500mc machine check conditions are made recoverable (as long as they aren't stuck on), most notably L1 instruction cache parity errors.

* powerpc/47x: Base ppc476 supportDave Kleikamp2010-05-051-0/+13
| | | | | | | | | | | | | | | | This patch adds the base support for the 476 processor. The code was primarily written by Ben Herrenschmidt and Torez Smith, but I've been maintaining it for a while. The goal is to have a single binary that will run on 44x and 47x, but we still have some details to work out. The biggest is that the L1 cache line size differs on the two platforms, but it's currently a compile-time option.

* powerpc/perf: e500 supportScott Wood2010-03-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | 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.

* powerpc adjust oprofile_cpu_type version 3Michael Wolf2009-05-011-4/+9
| | | | | | | | | | | | | Oprofile is changing the naming it is using for the compatibility modes. Instead of having compat-power<x>, oprofile will go to family naming convention and use ibm-compat-v<x>. 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.

* powerpc: Make sure we copy all cpu_spec features except PMC related onesMichael Ellerman2009-03-111-12/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | When identify_cpu() is called a second time with a logical PVR, it only copies a subset of the cpu_spec fields so as to avoid overwriting the performance monitor fields that were initialized based on the real PVR. However some of the other, non performance monitor related fields are also not copied: * pvr_mask * pvr_value * mmu_features * machine_check The fact that pvr_mask is not copied can result in show_cpuinfo() showing the cpu as "unknown", if we override an unknown PVR with a logical one - as reported by Shaggy. So change the logic to copy all fields, and then put back the PMC related ones in the case that we're overwriting a real PVR with a logical one.

* powerpc/fsl-booke: Cleanup init/exception setup to be runtimeKumar Gala2009-01-281-0/+8
| | | | | | | | | | | | | | | | | | We currently have a few variants of fsl-booke processors (e500v1, e500v2, e500mc, and e200). They all have minor differences that we had previously been handling via ifdefs. To move towards having this support the following changes have been made: * PID1, PID2 only exist on e500v1 & e500v2 and should not be accessed on e500mc or e200. We use MMUCFG[NPIDS] to determine which case we are since we only touch PID1/2 in extremely early init code. * Not all IVORs exist on all the processors so introduce cpu_setup functions for each variant to setup the proper IVORs that are either unique or exist but have some variations between the processors Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

It contain code to register CPU sysdevs in sysfs and add various properties such as cache topology and raw access by root to performance monitor counters (PMCs). A lot of that can be re-used as is on 32-bits. This makes the file be built for both, with appropriate ifdef'ing for the few bits that are really 64-bit specific, and adds some support for the raw PMCs for 75x and 74xx processors.

* powerpc: Indicate which oprofile counters to use while in compat modeTorez Smith2008-07-221-0/+20
| | | | | | | | | | | | | | | | | | | | | | While running on a system with new hardware and a kernel where the cpu_specs[] table does not recognize the new hardware, the identify_cpu() routine will select the default case as it searches through cpu_specs[] in an attempt to match the real PVR. Once the default case is selected, non of the oprofile counters and/or fields have been set up or defined. When identify_cpu() is called once more with the logical PVR, some of the cpu specific fields are replaced with the exception of the oprofile related ones. However, in the case where we have actually taken the default case while searching for the real PVR, we need to tell oprofile that we are now running in compatibility mode so it can pick up the correct counters. We do this by setting the oprofile_cpu_type field to be that taken from the cpu_specs[] for the cpu we are now emulating. This change will detect that we are now altering the real PVR and determine if we also need to update the oprofile_cpu_type field.

* powerpc: Add PPC_FEATURE_PSERIES_PERFMON_COMPATNathan Lynch2008-07-151-2/+4
| | | | | | | | | | | | | | | | | | | | | Background from Maynard Johnson: As of POWER6, a set of 32 common events is defined that must be supported on all future POWER processors. The main impetus for this compat set is the need to support partition migration, especially from processor P(n) to processor P(n+1), where performance software that's running in the new partition may not be knowledgeable about processor P(n+1). If a performance tool determines it does not support the physical processor, but is told (via the PPC_FEATURE_PSERIES_PERFMON_COMPAT bit) that the processor supports the notion of the PMU compat set, then the performance tool can surface just those events to the user of the tool. PPC_FEATURE_PSERIES_PERFMON_COMPAT indicates that the PMU supports at least this basic subset of events which is compatible across POWER processor lines.

| | | | | | | | The e300 c3 and c4 variants support hardware performance monitor counters which are identical to those found in the e500. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Made FSL Book-E PMC support more genericAndy Fleming2008-02-051-2/+2
| | | | | | | | | | Some of the more recent e300 cores have the same performance monitor implementation as the e500. e300 isn't book-e, so the name isn't really appropriate. In preparation for e300 support, rename a bunch of fsl_booke things to say fsl_emb (Freescale Embedded Performance Monitors).

* [POWERPC] 4xx: Add PowerPC 440EP Rev CSean MacLennan2008-01-251-0/+12
| | | | | | | | This adds the 440EP revision C PVR to the CPU table. The chip has an FPU on it, so we also match the logical PVR Signed-off-by: Sean MacLennan <smaclennan@pikatech.com> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
