| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Oprofile ARMv7 the PMNC_D bit was set to lower the PMU IRQs and so to decrease the risk of errata #628216 from appearing. The effect of setting the PMNC_D bit is that the CCNT counter is divided by 64, making the program counter events count inaccurate. The new OMAP3 r4 cores should have that errata fixed. The PMNC_D bit should not be set, this patch fixes it. Signed-off-by: Jean Pihet <jpihet@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

By moving this code to exit_thread(), we will be running as the thread, and therefore be running on the current CPU. This means that we can ensure that the only local state is accessed in the thread notifiers.

This allows the driver to get DMA-like performance where there are either no free DMA channels or when doing transfers that required both TX and RX data paths. Since this patch requires the addition of an assembly file to hold the FIQ code, we rename the module (instead of adding a rename of the .c file to this patch). We expect most users are loading this via udev and thus there should be no change to the userland configuration.

We gain no advantage in the cache controller stalling the bus until completion. What we should be doing is using the 'wait' time productively by calculating the address of the next operation, and only then waiting for the previous operation to complete. This means that cache operations can occur in parallel with the CPU calculating the next address.
