I have done some things as follow:
1, I have changed the tiler view by modify the DMM_TILER_OR_0/1 register value in the file dmm.c of the dmm-tiler driver for linux,
struct dmm *dmm_pat_init(u32 id)
{
__raw_writel(0x88888888, dmm->base + DMM_TILER_OR__0);
__raw_writel(0x88888888, dmm->base + DMM_TILER_OR__1);
}
--->modified to
struct dmm *dmm_pat_init(u32 id)
{
__raw_writel(0xcccccccc, dmm->base + DMM_TILER_OR__0);
__raw_writel(0xcccccccc, dmm->base + DMM_TILER_OR__1);
}
Or
struct dmm *dmm_pat_init(u32 id)
{
__raw_writel(0xffffffff, dmm->base + DMM_TILER_OR__0);
__raw_writel(0xffffffff, dmm->base + DMM_TILER_OR__1);
}
2, reconfigured the linux kernel to support the TILER feature
Device Drivers-->Multimedia support-->TI TILER support
3, In our app,
I have tried to set capturePrm->tilerEnable = TRUE;
Or deiPrm-> tilerEnable = TRUE;
Or nsfPerm-> tilerEnable = TRUE;
Or the combination of capturePrm -> tilerEnable = TRUE; and deiPrm-> tilerEnable = TRUE; and nsfPerm-> tilerEnable = TRUE;
But I don’t get the result which I want, and I got the result that the video did’t have been rotation.
Can anyone help me, or give me some source codes or documents for reference about how to realize the feature of rotation/mirroring by TILER?
