Looping in linux-arm ML:
Discussion Ref: [1](linux-omap mailing list)
While working with Linux OMAP kernel[2] we found that on allocating 4 meg
chunks using dma_alloc_coherent and de-allocating with dma_free_coherent in a
loop using a test driver[7], the memory is getting fragmented as shown by

Elaborate please? The regulator framework complains

If MPU goes to WFI in the idle thread, execution time becomes a bit
slow and the JTAG Debugger doesn't work. This patch is needed for
urgent works(e.g. booting and launching application) and debugging.
To enable sleep_while_idle mode, use below setting.
echo 1 /sys/power/sleep_while_idle

Hi,
I have a few questions regarding using the TI OMAP GPMC and SDMA
together with an external device.
Question 01: How can I set up the multiplexing modes for the TI OMAP
3503 GPMC and SDMA controller ? The GPMC has 4 multiplexing options/
modes and the SDMA has 8 modes of operation.
Hi Tony,
I think I can join you. And also Kyungmin Park I guess.
See you then.
