hello coreboot bois and girlz,i have succesfully booted my system with the Richland CPU installed with a Nvidia GT210 card.
also it seems that IOMMU is working now... maybe cause i have microcode updates in the kernel included this time ? so i have to change my bugreport as it seems that this coreboot port + Seabios has somehow problems with Radeon Cards .... both the IGPU and addon cards will feed your with extra news. your kinky nekoboi Am 17.04.19 um 11:23 schrieb Kinky Nekoboi: > i have tried builds for F2A85M since version 4.8 dating back to mid 2018, > > AMD-A8 5500 works properly with IOMMU enabled, still some stabilty > problems (full system freezes). > > AMD A8-6600K shows the described behavior > > I also tried that manual microcode update in the past, didnt change > anything there, i could retry it for the current build. > > Serial output gives no information about malfunctioning IOMMU or > something, the strugle begins as without IOMMU the system is notable to > initialize add-on videocards or the iGPU. > > Am 17.04.19 um 10:50 schrieb Mike Banon: >> On Tue, Apr 16, 2019 at 11:23 PM Kinky Nekoboi >> <[email protected]> wrote: >>> Amd-Vi loopback errors at linux-boot, >>> several peripherie is not working. >>> >>> Surely it needs only minor changes... is there anybody working at this >>> port at the moment? >>> >> Hi there Nekoboy (sorry if I'm repeating my older questions, I >> forgot).
