![]() ![]() Whatever the case, it's coming much later than the rest of the MI300 / GFX940 Linux enablement and given AMD's Linux driver enablement cadence this product won't be launching for a number of months if not until 2024.Īt the earliest these initial enablement patches will appear in Linux 6.4 but will likely take a cycle or two (if not longer as is commonly the case with new kernel GPU driver code) for all the new GPU enablement code to get squared away depending upon how different this new GPU is and whether more invasive driver changes are needed. ![]() Namely whether this is for some new Instinct MI300 derivative part like an Instinct MI310/MI350 or if it's for a more pronounced offering like MI400. AMD Video Core Next 4.0 debuted with Navi 3x (RDNA3) GPUs while this updated VCN 4.0.3 IP is being found with the new CDNA GPU.Īs for what this new part is can't be entirely figured out yet based on the limited patches published thus far. ![]() This VCN 4.0.3 enablement is related to this new GPU target and among other improvements brings multiple JPEG rings. ![]() These patches further confirm that this new GPU target is another Aldebaran-derived target currently comprising the Instinct MI200 and MI300 series.įor the most part this new GPU is following the existing Aldebaran code paths within the AMDGPU and AMDKFD drivers though following that KFD GFX943 enablement were another 28 patches making further modifications.Īmong the patches is confirmation of multi-XCC support with this new GPU.Īlso sent out today were patches for VCN 4.0.3 support. Of course, a very important part for AMD Instinct accelerators and is the kernel portion for enabling the ROCm compute stack. The AMDKFD "Kernel Fusion Driver" is the compute kernel driver side. New patches posted today were KFD patches for GC 9.4.3, one of the new IP block versions mentioned in the earlier article. As pointed out in that earlier article, it looks to be a new AMD Instinct MI300 / "Aldebaran" GPU model and today more patches were posted that further confirm this target. Over the weekend I wrote about AMD beginning to post new graphics driver patches for a new GPU. ![]()
