* dmaengine: PL08x: remove runtime PM supportRussell King2012-07-011-10/+0
| | | | | | | | | | | | | | The runtime PM support conflicts with the generic AMBA bus PM, and also causes a potential deadlock with the PL011 driver as it results in interrupts being enabled beneath a spinlock. I don't presently see any solution to this other than by removing the runtime PM support entirely from the DMA engine driver. Alternative suggestions welcome.

* dmaengine: virt-dma: add support for cyclic DMA periodic callbacksRussell King2012-07-012-4/+29
| | | | | | | | | | | | | Add support for cyclic DMA's periodic callbacks. Drivers are expected to call vchan_cyclic_callback() when a period has completed, which will schedule the tasklet to make the callback into the driver. As callbacks are made from tasklet context, it is important to realise that we don't guarantee a callback for each completed period, but for N completed periods where N may be greater than one.

The problem is that the isolated_cpus_lock mutex is owned when destroy_power_saving_task() calls kthread_stop(), which waits for a power_saving thread to end, and the power_saving thread tries to acquire the isolated_cpus_lock when it calls round_robin_cpu(). This patch fixes the issue by making round_robin_cpu() use its own mutex. https://bugzilla.kernel.org/show_bug.cgi?id=42981 Cc: stable@vger.kernel.org Signed-off-by: Stuart Hayes <Stuart_Hayes@Dell.com> Signed-off-by: Len Brown <len.brown@intel.com>

This patch fixes the regression that caused this issue in the first place. acpi_idle_suspend flag is essential on some x86 systems to prevent the cpus from going to deeper C-states when suspend is triggered ( commit b04e7bdb984 ) So reverting the commit 3439a8da is essential. By default, irqs are disabled in cpu_idle arch specific call and re-enabled in idle state return path . During suspend, the acpi_idle_suspend flag is set, which prevents the cpus from going to deeper idle states, it is essential to enabling the irqs in this return path too. To address the suspend issue, we were not re-enabling the interrupts while returning from acpi_idle_enter_bm() routine if acpi_idle_suspend flag is set. and this caused suspend failure. In addition to the above, to improve the readability of the code, return of -ENIVAL is replaced with -EBUSY in acpi_idle_suspend return path. Implying that the system is currently busy when suspend is in progress, which prevents the cpus from entering deeper C-states.

Still, we have reports of this being seen in the wild. Now Bspec has this little bit of lovely language in the PMIIR register: Public SNB Docs, Vol3Part2, 2.5.14 "PMIIR": "For each bit, the IIR can store a second pending interrupt if two or more of the same interrupt conditions occur before the first condition is cleared. Upon clearing the interrupt, the IIR bit will momentarily go low, then return high to indicate there is another interrupt pending." Now if we presume that PMIMR only prevent new interrupts from being queued, we could easily end up masking an interrupt and clearing it, but the 2nd pending interrupt setting the bit in PMIIR right away again. Which leads, the next time the irq handler runs, to hitting the WARN. Also, no bad side effects of this have ever been reported. And we've tracked down our issues with the gpu turbo getting stuck to bogus interrupt generation limits in th RPLIMIT register. So let's just rip out this WARN as bogus and call it a day. The only shallow thing here is that this 2-deep irq queue in the hw makes you wonder how racy the windows irq handler is ...

This was resulting in the FCoE DDP logic having issues since it thought the frame still had data in it due to the padding. To resolve this, adding code so that we do not pad FCoE frames prior to handling them to the stack.
