I used kernel 2.6.18, when I run a application on kernel, I got a error as

BUG: unbalanced irq-handler preempt count in dma_irq_handler_l+0x0/0x24!
Anyone can give me any clue? Thanks very much.

Hi Gopal,
I think user pointer buffer exchange mechanism is supported in both the
drivers, so you can allocate buffers in one driver and use it in the other
driver without doing memcpy.
Thanks,

Sounds like a bug in dma_irq_handler... may not be preemption safe.

I can think of two options before you.
1. Try debugging the problem yourself and post specific questions on
this list. There are a lot of very helpful folks here.

I have now added clk_enable(), clk_disable to my driver. But I see the
following logs randomly when the board is powered. I have

This is a buildfix for the DaVinci PCM code, resyncing it with
the version in the DaVinci tree. The notable change is using
current EDMA interfaces, which recently merged to mainline.
(The older interfaces never made it into mainline.)
NOTE:
The 2.6.30-rc5 merges included a bunch of DaVinci platform
updates, including EDMA support. Which means that finally
the ASoC stuff can be made to build in mainline ... it was
probably sent to mainline before its time. ;)
Following are three patches which resync mainline ASoC code

I see that mount time of yaffs2 file system on NandFlash becomes too long when
it has more files in it.
A 500 MB nand flash partition which is 90% full is taking over a minute to

Can anyone help me to reduce the time.

thanks Deepak:
I have configed kernel by the command :
make ARCH=arm CROSS_COMPILE=arm_v5t_le- davinci_dm355_defconfig
make ARCH=arm CROSS_COMPILE=arm_v5t_le- uImage
use the default configs for dm355,the kernel can't been boot up,I have Enabled
kernel hacking-kernel debuging-low
I faced similar issue when switching between kernel builds for different
platforms. In such cases, a proper/full clean before build helped in getting
the right uImage built. Probably, you can try that too.
make distclean
make ARCH=arm CROSS_COMPILE=arm_v5t_le- davinci_dm355_defconfig
make
Now I am waiting for reply from TI FAE too. I am using 2.6.10 kernel.
Has anyone the same problem like me .

Could anyone please show me how to use DMA from/to SRAM for audio driver? I
just checked the 2.6.30 kernel and found the SRAM allocator was added in it.

Hi
Go to menuconfig, kernel Features- select “allow old ABI binaries to run with
this kernel” or disable the “ARM EABI to compile the kernel”. Then do clean
build. This should resolve the issue.
