Also driver touches FDADR1 on main plane reconfiguration, and it can cause problems if overlay1 is enabled. This patch attempts to fix those issues. Patch is based on Russell King's work.

On a v7 processor, an mrc with the pc sets the condition codes to the 28-31 bits of the register being read. It just so happens that the TX/RX full bits the DCC support code is testing for are high enough in the register to be put into the condition codes. On a v6 processor, this "feature" isn't implemented and thus we have to do the usual read, mask, test operations to check for TX/RX full. Thus, we can drop the v7 implementation and just use the v6 implementation for both.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Rn value from the emulation is unconditionally written back; this is fine as long as Rn != PC because in that case, even if the instruction isn't a write back instruction, it will only result in the same value being written back. In case Rn == PC, then the emulated instruction doesn't have the actual PC value in Rn but an adjusted value; when this is written back, it will result in the PC being incorrectly updated. An altenative solution would be to check bits 24 and 22 to see whether the instruction actually is a write back instruction or not. I think it's enough to check whether Rn != PC, because: - it's looks cheaper than the alternative - to my understaning it's not permitted to update the PC with a write back instruction, so we don't lose any ability to emulate legal instructions. - in case of writing back for non write back instructions where Rn != PC, it doesn't matter because the values are the same. Regarding the second point above, it would possibly be prudent to add some checking to prep_emulate_ldr_str(), so that instructions with both write back and Rn == PC would be rejected.

Unfortunately, the event update code will not realise an overflow has occurred and will instead report the event delta as (new - prev) which may be considerably smaller than the real count. This patch adds an extra argument to armpmu_event_update which indicates whether or not an overflow has occurred. If an overflow has occurred then we use the maximum period of the counter to calculate the elapsed events.

| * | | | | | | ARM: 6834/1: perf: reset counters on all CPUs during initialisationWill Deacon2011-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARMv7 dictates that the interrupt-enable and count-enable registers for each PMU counter are UNKNOWN following core reset. This patch adds a new (optional) function pointer to struct arm_pmu for resetting the PMU state during init. The reset function is called on each CPU via an arch_initcall in the generic ARM perf_event code and allows the PMU backend to write sane values to any UNKNOWN registers.

This patch adds two isbs to the ARMv7 perf code: (1) Immediately after selecting an event register, so that the PMU state following this instruction is consistent with the new event. (2) Immediately before writing to the PMCR, so that any previous writes to the PMU have taken effect before (typically) enabling the counters.
