Hello Rodrigo, i'm facing some issue running basic IGT tests with GUC 6.1
enabled, sharing my configuration.
GuC 6.1: <a href="https://01.org/linuxgraphics/downloads/skylake-guc-6.1">https://01.org/linuxgraphics/downloads/skylake-guc-6.1</a>
Kernel: 4.8.0-rc7_3c9e639/
Commit git_commit=3c9e639197bb52280334830e611082d5b6bfaceb
Intel Gpu Tools : intel-gpu-tools-1.16-36-gd16318a
Hardware: : Intel(R) Core(TM) i5-6260U CPU @ 1.80GHz
Behavior:
In a 244 test suites, after i got the first time out, all the others tests
still facing the same behavior taking more than 10 minutes to execute, this
causes a time out signal failing the test. Something completely different if i
remove the guc firmawre.
Example:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
4238 root 20 0 57984 2276 1888 R 100.0 0.0 7:31.08
kms_addfb_basic
1 root 20 0 119880 5996 3944 S 0.0 0.0 0:02.84 systemd
2 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kthreadd
3 root 20 0 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/0
5 root 0 -20 0 0 0 S 0.0 0.0 0:00.00
kworker/0:0H
7 root 20 0 0 0 0 S 0.0 0.0 0:01.11 rcu_sched
8 root 20 0 0 0 0 S 0.0 0.0 0:00.00 rcu_bh
Values so far with Guc 6.1 enabled:
Launch IGT basic tests with GuC loaded pass 220 skip 14 timeout 7
incomplete 1 fail 1 dmesg-warn 1
Values without GUC
Launch IGT basic tests with GuC not loaded pass 229 skip 13
dmesg-war 1 fail 1
Attaching dmesg during igt execution with timeouts.</pre>
