iMX6SX framebuffer image rotation

[texnikk]

Q: Does anybody know, how can framebuffer rotation be achieved on iMX6SX cpu, which doesn't have IPU?

Because I've found several threads here regarding image rotation, but looks like all solutions require usage of IPU.

[texnikk]

So maybe there are any other solutions?

You can use the PXP engine to rotate a buffer and render back to the frame buffer as shown in this example.

Hi Serhii

one can look at pxp rotation test

pxp_v4l2_test.c\pxp_v4l2_test\test - imx-test - i.MX Driver Test Application Software

Hi igorpadykov,

Thanks for your reply!

Well, actually I need this rotation be performed by framebuffer driver itself, like it was described in i.MX6 IPU and rotating a frame buffer in framebuffer_rotaion_90_degree_kernel_4.9.patch.zip , not from userspace
