Using of OMAP ISP Resizer module

Hello!
I built omap_resizer module as explained in http://wiki.maemo.org/Documentation/...o_Kernel_Guide

Then I compiled test program which use omap_resizer module for resize some test image. But omap_resizer module is stuck on function

Code:

wait_for_completion_interruptible(&device_config->compl_isr);

This interrubtible is completed in callback function

Code:

rsz_isr

which sets as callback by calling isp_mod`s function:

Code:

isp_set_callback(fh->dev, CBK_RESZ_DONE, rsz_isr, (void *) NULL,

                                                        (void *)NULL))

As you see, callback is set for event CBK_RESZ_DONE.

But this callback is never being called...

Any ideas?

Re: Using of OMAP ISP Resizer module

I investigated maemo kernel sources for ISP module. And found that ISP in function isp_set_callback not control CBK_RESZ_DONE event! They contol only CBK_PREV_DONE!!! :confused:

Code:

switch (type) {

        case CBK_PREV_DONE:

                isp_reg_writel(dev, IRQ0ENABLE_PRV_DONE_IRQ,

                               OMAP3_ISP_IOMEM_MAIN, ISP_IRQ0STATUS);

                isp_reg_or(dev, OMAP3_ISP_IOMEM_MAIN, ISP_IRQ0ENABLE,

                           IRQ0ENABLE_PRV_DONE_IRQ);

                break;

        default:

                break;

        }

And now how to use resizer module in maemo without rebuilding kernel with correct isp module? :(
