I am a bit confused on the interrupt number for CNTVIRQ..CNTHPIRQ. Can
you please help here.
As per the exynos5 public manual
What is the difference between CPU_nCNTHPIRQ[0] and CNTHPIRQ.
I'm not sure if this is really what I think it is, but looking at the
manual, CPU_nCNTHPIRQ[0] and [1] SPI ports and CNTHPIRQ PPI port seem to
be the same signals, with the difference that the first two are shared
interrupts connected through the combiner, while the last one is a
per-processor interrupt, directly connected to GIC PPI port, allowing
each CPU to get its own CNTHPIRQ signal ([0] for CPU 0 and [1] for CPU 1).
Best regards,
Tomasz
While the later has an interrupt ID 26, the former is part of a group
with combined interrupt id as 33 for core 0 and 54 for core 1.
For a timer interrupt which goes to PL2, which id should be used 26 or
33 for core 0 ?
Please clear this confusion.
Many Thanks
