So IOMMU is working for you even with 0x0600111f microcode installed? That's very good. I wonder what was wrong initially, and hope that you could send a board status report or - at least - please upload your current .config to somewhere (e.g. pastebin) and post a link!
> are there any other blobs present in my rom now besides microcode ? The microcode blob has been present in your coreboot even before my ucode.sh patch, it just was an older 0x0600110f version (more vulnerable to some spectres and perhaps more buggy IOMMU - e.g. at our G505S we could get IOMMU working properly only with this 0x0600111f update). > my build rom in attachment for inspection I can't see it - perhaps the mailing list didn't accept this big attachment. > AMD SMU firmware Have you tried running this free firmware replacement ( https://github.com/zamaudio/smutool/) and is it working? You could also check about the IMC. Read the latest messages at this page: https://mail.coreboot.org/hyperkitty/list/coreboot@coreboot.org/thread/IAFQRF7264GGQRNEWLUKGRUO4KSHTELB/ They contain the instructions about how to check that your IMC is inactive On Sat, Apr 20, 2019 at 11:11 AM Kinky Nekoboi <kinky_neko...@nekoboi.moe> wrote: > > > > -------- Weitergeleitete Nachricht -------- > Betreff: Re: [coreboot] Re: Fwd: Re: Fwd: F2A85M IOMMU still not working > for RIchland CPUS > Datum: Thu, 18 Apr 2019 16:24:42 +0200 > Von: Kinky Nekoboi <kinky_neko...@nekoboi.moe> <kinky_neko...@nekoboi.moe> > An: Mike Banon <mikeb...@gmail.com> <mikeb...@gmail.com>, > coreboot@coreboot.org > > did this. > > sudo dmesg | grep microcode > [ 1.177705] microcode: CPU0: patch_level=0x0600111f > [ 1.177708] microcode: CPU1: patch_level=0x0600111f > [ 1.177715] microcode: CPU2: patch_level=0x0600111f > [ 1.177722] microcode: CPU3: patch_level=0x0600111f > [ 1.177761] microcode: Microcode Update Driver: v2.2. > > works like a charm. > > please inform me if this is still the case: (from libreboot side) > > are there any other blobs present in my rom now besides microcode ? > > /* my build rom in attachment for inspection.
