Subject: [igt-dev] [PATCH i-g-t] tests/kms_big_fb: Add assert for drm_intel_bufmgr and intel_batchbuffer before usage
Date: Thu,  8 Aug 2019 18:04:57 +0530	[thread overview]
Message-ID: <1565267697-19510-1-git-send-email-swati2.sharma@intel.com> (raw)

if drm_intel_bufmgr_gem_init() or intel_batchbuffer_alloc()
returns NULL, it leads to seg fault as below:

root@testrunner:/home/testrunner/swati/otc_gen_graphics-intel-gpu-tools#
./tests/kms_big_fb
IGT-Version: 1.24-g976db91 (x86_64) (Linux: 5.1.0-rc6+ x86_64)
Max driver framebuffer size 8192x8192
RAM: 2749 MiB, GPU address space: 134217728 MiB, GGTT mappable size: 256
MiB
Received signal SIGSEGV.
Stack trace:
 #0 [fatal_sig_handler+0x77]
 #1 [killpg+0x40]
 #2 [drm_intel_bo_alloc+0x0]
 #3 [intel_batchbuffer_reset+0x33]
 #4 [intel_batchbuffer_alloc+0x34]
 #5 [__real_main603+0x3e9]
 #6 [main+0x23]
 #7 [__libc_start_main+0xf0]
 #8 [_start+0x29]
 #9 [<unknown>+0x29]
Segmentation fault (core dumped)

To prevent this igt_assert() is added for both the functions.
