Subject: gpu: nova-core: increase BAR0 size to 16MB
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=94a08721435cc9a8de9f9ce83e9fe13d38d24771;p=thirdparty%2Flinux.git

gpu: nova-core: increase BAR0 size to 16MB

The Turing+ register address space spans over that range, so increase it
as future patches will access more registers.
