Severity: important
Tags: patch upstream
Hi,
Whenever I start Nageru on my Kaby Lake laptop, it segfaults in the VA driver.
This was fine in 20.3.0+ds1-1, broke in 20.4.1+ds1-1, and is still the case
in 20.4.2+ds1-1. However, compiling upstream 20.4.3 appears to fix it.
This is the relevant patch according to bisect:

[Media Common] Integrate new gmm API for external surface
Integrate new gmm API to create gmmResInfo for external surface.
Need to update gmm to intel-gmmlib-20.3.3.
This is the backtrace:
Thread 15 "QS_Encode" received signal SIGSEGV, Segmentation fault.
