imx6q mxc_sdc_fb timeout when waiting for flip irq

moseeneview — Thu, 17 Apr 2014 11:54:09 GMT

sometimes, my imx6q board gets timeout when waiting for flip irq with rate 10~20%.

mxc_ipuv3_fb.c:

it seems there's not irq to do complete. and then it wait_for_completion_timeout.

hwcomposer/hwc_vsync.cpp

FBIO_WAITFORVSYNC error: time expire

i try as below, the issue also come out sometime. could u tell me why or some advice. thx.

1） Wait longer: wait_for_completion_timeout(&mxc_fbi->flip_complete, 4*HZ);

2) ldb_data = {

.ipu_id = 1, # or use ipu 0

.disp_id = 0,

.ext_ref = 1,

.mode = LDB_SIN0,

}

ldb_data = {

.ipu_id = 1,

.disp_id = 0,

.ext_ref = 1,

.mode = LDB_SEP0,

.sec_ipu_id = 1,

.sec_disp_id =1,

}

3) fb_data = {

{ /*fb0*/

.disp_dev = "ldb",

.interface_pix_fmt = IPU_PIX_FMT_RGB666,

.mode_str = "LDB-XGA",

.default_bpp = 16,

.int_clk = false,

.late_init = true, # or false

}

ipu_data[] = {

{

.rev = 4,

.csi_clk[0] = "clko_clk",

.bypass_reset = false,

}, {

.rev = 4,

.csi_clk[0] = "clko_clk",

.bypass_reset = false,

};

We are analyzing your inquiry can you please let us know if, waht board are you using? and what Linux BSP ?

Re: imx6q mxc_sdc_fb timeout when waiting for flip irq

moseeneview — Tue, 22 Apr 2014 03:04:01 GMT

hi, jamesbone. thx for your reply. we're using imx6q custom board based on sabresd with jb4.3 1.1.0 bsp.

Re: imx6q mxc_sdc_fb timeout when waiting for flip irq

jamesbone — Tue, 22 Apr 2014 14:22:38 GMT

But how do you run into this case? Is the framebuffer driver in blanking state at that time?

Qiang_FSL Apr 21, 2014 6:59 PM (in response to jamesbone)

From the log we can only know the IPU display is not working correctly. But how do the customer run into this case? Is the framebuffer driver in blanking state at that time?

Re: imx6q mxc_sdc_fb timeout when waiting for flip irq

moseeneview — Tue, 22 Apr 2014 15:05:14 GMT

In a mater of fact, i haven't found out the real reason. But when i power

off/on my device time and time again, it'll run into this case randomly.

Besides, what do u mean blanking state?

qiang_li-mpu_se — Wed, 23 Apr 2014 02:39:55 GMT

If the IPU display IDMAC is not enabled (framebuffer in blanking state), the PAN display will get such timeout information.

And if the IDMAC is in wrong state, it can also make PAN display timeout.

Maybe you can add more debug messages in ipu_common.c to check the IDMAC, such as ipu_disable_channel(), ipu_enable_channel(), ipu_init_channel(), ipu_uninit_channel().

Re: imx6q mxc_sdc_fb timeout when waiting for flip irq

moseeneview — Mon, 28 Apr 2014 06:55:50 GMT

hi Qiang Li, I didn't get IDMAC error. and i get this issue rondomly, not always.

Re: imx6q mxc_sdc_fb timeout when waiting for flip irq

qiang_li-mpu_se — Tue, 06 May 2014 03:05:00 GMT

"Power off/on the device" is it suspend/resume test or power off/on reboot test? If it is the whole system reboot, can you attach the whole kernel boot log?

What's your display device? LCD, LVDS, HDMI? Single display or multi-display? Did you change any IPU related code in your BSP? In whcih case will you do the suspend/resume? Just idle on home screen?

I am also facing the same kind display issue with "mxc_sdc_fb timeout when waiting for flip irq" message.I am doing power ON and OFF for getting the issue.Our display device is LVDS,single display.We did not make any change in IPU related code.

not yet.

i try to improve LCD timing（ldb） which is matter with ipu.

and then it seems to cut down the rate.

but i haven't solved this issue yet.

Re: imx6q mxc_sdc_fb timeout when waiting for flip irq

qiang_li-mpu_se — Fri, 20 Jun 2014 05:37:08 GMT

From my point, some wrong IPU setting can cause the SYNC display error, then there will be "timeout when waiting for flip irq" error, but if you only modified the timing parameters for display mode, the test result should be same as original BSP.
