system does not support display interrupts..


#1

I am working on “SGX_DDK_Linux_REL_1.9.RC2@2139099_ogles1_ogles2_source_um” & "SGX_DDK_Linux_REL_1.9.RC2@2139099_source_km"

our aim is to verify above SDK for SGX core present on Beaglebone. And we are booting beaglebone with ubuntu-12.10 & building above SDK natively. We are able to build & load the driver from nohw_linux platform with very little debugging. And able to run basic unit-test for EX : sgx_init_test, sgx_clip_blit_test. But when we are trying to run sgx_render_flip_test, am getting strange response. Am unable to trace the reason , below is the error.



1:- ./sgx_render_flip_test





This system does not support display interrupts, so a non-zero swap (flip) interval is not supported.



Consider using a zero swap interval using the option -si 0





2:- ./sgx_render_flip_test -si 0





Swap Interval: 0



This system does not support interrupts, so the Event Object not supported.



Consider disabling the Event Object using the option -neo





3:- ./sgx_render_flip_test -si 0 -neo





Swap Interval: 0



Event Object: DISABLED

Hi Prakash,



We (DevTech) cannot support questions related to configuring and building the graphics driver. These queries must go through the platform provider (TI, in this case) or - if you are a DDK licensee - through our IP Gear customer support system.
