[coreboot] Re: Fwd: Re: Fwd: Re: Fwd: F2A85M IOMMU still not working for RIchland CPUS
For some reason the config inside your rom is trimmed and includes just 5 lines: # This image was built using coreboot 4.9-1334-gdb3f0e3ebd-dirty CONFIG_VENDOR_ASUS=y CONFIG_BOARD_ASUS_F2A85_M=y CONFIG_HUDSON_XHCI_FWM=y # CONFIG_DRIVERS_INTEL_WIFI is not set Perhaps that's indeed the only difference from default config - but why IOMMU wasn't working initially, then? That's still a mystery, and I would appreciate if you could send the full .config from your coreboot build directory to complete the investigation. By the way, I noticed that you have CONFIG_HUDSON_XHCI_FWM=y . Enabling the CONFIG_HUDSON_XHCI_ENABLE / CONFIG_HUDSON_XHCI_FWM options results in XHCI blob being added to your coreboot image - it is hidden inside the " apu/amdfw 0x1fdc0 raw 66048 ". If you'd like your coreboot build to get closer to libreboot, you could get rid of XHCI blob by disabling these options. Also, it seems that you either forgot to add the AtomBIOS blob for your integrated GPU (pci1002,.rom), or plan to use this board in a headless mode. I'm not sure if it is possible to get the graphical output without it... ( if I'm wrong, how are you getting it? using that Nvidia GT210 which is running its' own blob? ) Best regards, Mike Banon On Mon, Apr 22, 2019 at 8:42 AM Kinky Nekoboi wrote: > Here is the filelink: > > https://nekoboi.moe/nextcloud/index.php/s/DfYGsdNzHHxGKHA > > the .config file should be included in the rom. > Am 21.04.19 um 20:13 schrieb Mike Banon: > > SMU is still inside your coreboot build, it's just hardcoded as an array > of hex values inside the > ./coreboot/src/vendorcode/amd/agesa/f15tn/Proc/GNB/Modules/GnbInitTN/GnbSmuFirmwareTN.h > file.

SMU is still inside your coreboot build, it's just hardcoded as an array of hex values inside the ./coreboot/src/vendorcode/amd/agesa/f15tn/Proc/GNB/Modules/GnbInitTN/GnbSmuFirmwareTN.h file. That's why you couldn't see SMU firmware as a separate binary at your CBFS. Just like a microcode, which is also set up inside some .c/.h files. Yes, please send your working build when it's possible, and also your current ./coreboot/.config please - this is also very important.

[coreboot] Re: Fwd: Re: Fwd: Re: Fwd: F2A85M IOMMU still not working for RIchland CPUS
Yes IOMMU works fine with 0x0600111f microcode. No i dont tried the reversed eng. SMU when it is no already inside coreboot. I wasnt able to send an email attached with my rom file ... i am not at home right now so i will provied your with a file link to my rom later .. proberally on Tuesday. IMC was dropped out of the standart config and also out of the nconfig menu as i experienced. You can see this in the absensce of fan control ( what is not problem if you have a FAN that is not extrem loud at 12V) Am 21.04.19 um 09:29 schrieb Mike Banon: > So IOMMU is working for you even with 0x0600111f microcode installed? > That's very good.

[coreboot] Re: Fwd: Re: Fwd: Re: Fwd: F2A85M IOMMU still not working for RIchland CPUS
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.
