- * ARMv6 Performance counter handling code.
- *
- * ARMv6 has 2 configurable performance counters and a single cycle counter.
- * They all share a single reset bit but can be written to zero so we can use
- * that for a reset.
- *
- * The counters can't be individually enabled or disabled so when we remove
- * one event and replace it with another we could get spurious counts from the
- * wrong event. However, we can take advantage of the fact that the
- * performance counters can export events to the event bus, and the event bus
- * itself can be monitored. This requires that we *don't* export the events to
- * the event bus. The procedure for disabling a configurable counter is:
- * - change the counter to count the ETMEXTOUT[0] signal (0x20). This
- * effectively stops the counter from counting.
- * - disable the counter's interrupt generation (each counter has it's
- * own interrupt enable bit).
- * Once stopped, the counter value can be written as 0 to reset.
- *
- * To enable a counter:
- * - enable the counter's interrupt generation.
- * - set the new event type.
- *
- * Note: the dedicated cycle counter only counts cycles and can't be
- * enabled/disabled independently of the others. When we want to disable the
- * cycle counter, we have to just disable the interrupt reporting and start
- * ignoring that counter. When re-enabling, we have to reset the value and
- * enable the interrupt.

+ * ARMv6 Performance counter handling code.
+ *
+ * Copyright (C) 2009 picoChip Designs, Ltd., Jamie Iles
+ *
+ * ARMv6 has 2 configurable performance counters and a single cycle counter.
+ * They all share a single reset bit but can be written to zero so we can use
+ * that for a reset.
+ *
+ * The counters can't be individually enabled or disabled so when we remove
+ * one event and replace it with another we could get spurious counts from the
+ * wrong event. However, we can take advantage of the fact that the
+ * performance counters can export events to the event bus, and the event bus
+ * itself can be monitored. This requires that we *don't* export the events to
+ * the event bus. The procedure for disabling a configurable counter is:
+ * - change the counter to count the ETMEXTOUT[0] signal (0x20). This
+ * effectively stops the counter from counting.
+ * - disable the counter's interrupt generation (each counter has it's
+ * own interrupt enable bit).
+ * Once stopped, the counter value can be written as 0 to reset.
+ *
+ * To enable a counter:
+ * - enable the counter's interrupt generation.
+ * - set the new event type.
+ *
+ * Note: the dedicated cycle counter only counts cycles and can't be
+ * enabled/disabled independently of the others. When we want to disable the
+ * cycle counter, we have to just disable the interrupt reporting and start
+ * ignoring that counter. When re-enabling, we have to reset the value and
+ * enable the interrupt.

Say 'Y' here if you want to support the Marvell MMP2-base
Jasper Development Platform.
MMP2-based board can't be co-existed with PXA168-based &
PXA910-based development board. Since MMP2 is compatible to
- ARMv6 architecture.
+ ARMv7 architecture.

bool
- select CPU_V6
- select CPU_32v6K
+ select CPU_PJ4
help
- Select code specific to MMP2. MMP2 is ARMv6 compatible.
+ Select code specific to MMP2. MMP2 is ARMv7 compatible.
