https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206699 --- Comment #1 from Roger Pau Monn=C3=83=C2=A9 <royger@freebsd.org> --- I've already told Wei that creating your own bounce buffer is a bad idea. Instead you should use the BUSDMA API and let it take care of the bouncing = when necessary: https://reviews.freebsd.org/D1964 IIRC something was missing in BUSDMA so that the HyperV storage driver could use it, we should look into adding what's needed and then removing this cus= tom bounce buffering. Please upload the patch to the review system. Roger. --=20 You are receiving this mail because: You are on the CC list for the bug.=
