Subject: drm/amdgpu: Reserve space for IB contents in devcoredumps
X-Git-Tag: v7.2-rc4~13^2^2~18
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=b5eab15944b6b140f003af6e639a25f5c3a8ed0b;p=thirdparty%2Flinux.git

drm/amdgpu: Reserve space for IB contents in devcoredumps

Currently the contents of IBs are abruptly cut off and don't
show the full contents. This patch makes sure to reserve
space for those contents too so they may be printed.
