Thanks for the report. I have been unable to reproduce this, but then I don't see my tegra20 entering LP2 during cpuidle. I did force my tegra20 into LP2 during suspend which will exercise the same code but I did not trigger this either. However, from looking at the code it does appear that we could hit this.
As I wrote before, it's quite difficult to reproduce.
Ideally, it would be great if we did not need to add another custom API for this, but I did not find anything in the CCF that would allow us to avoid but that was only a quick look. However, we could ask the CCF folks.
Yes, CCF doesn't expose locked API. Code should be designed to avoid it.
What I plan to do next is to understand if the pclk is likely to change. I know that it comes from one of the plls but I am not sure if we ever change the rate. If not we may be able to move this to probe time and avoid this.
That's reasonable, I'd also take a look at it. Thanks for the comment! -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
