X-Git-Tag: v5.0-rc1~137^2~59 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bdbf649efe21173cae63b4b71db84176420f9039;p=thirdparty%2Fkernel%2Flinux.git powerpc/powernv/ioda: Allocate indirect TCE levels of cached userspace addresses on demand The powernv platform maintains 2 TCE tables for VFIO - a hardware TCE table and a table with userspace addresses; the latter is used for marking pages dirty when corresponging TCEs are unmapped from the hardware table. a68bd1267b72 ("powerpc/powernv/ioda: Allocate indirect TCE levels on demand") enabled on-demand allocation of the hardware table, however it missed the other table so it has still been fully allocated at the boot time. This fixes the issue by allocating a single level, just like we do for the hardware table.
