As far as I know, here are laptops that still get microcode updates (6th gen and later [11]) + have coreboot:
| Laptop | CPU cores | ME | EC | Qubes suspend |
|---|---|---|---|---|
| NovaCustom NS51, NS70 | 4 x Intel 11th | ? | ? | ? |
| Purism Librem 13v4, 15v4 | 2 x Intel 7th | minimizable [12] | ? | yes - see HCL |
| Purism Librem 14 | 6 x Intel 10th | factory-disabled | FOSS [5] | yes [9] |
| Starlabs Mk VI | 4+8 x Intel 12th | ? | ? | ? |
| Starlabs Mk V | 4 x Intel 11th | factory-disabled | proprietary [7] | yes [8] |
| System76 darp8 | 4+8 x Intel 12th | ? | FOSS | no? - 12th-gen |
| System76 galp5, lemp10 | 4 x Intel 11th | user-disabled [2] | FOSS [A] | no [10] |
| System76 oryp7, lemp9 | 4-8 x Intel 10th | ? | FOSS [A] | yes? - S3 |
| System76 galp3, galp3b | 4 x Intel 8th | factory-minimized? [4] | proprietary? [A][B] | yes? - S3 |
Note: Intel 11th-gen onwards dropped support for S3 sleep, replacing it with s0ix, which is not currently working in qubes.[1] Though certain Intel 11th-gen CPUs have working S3.[3]

[4]while upstream coreboot has option to run MECleaner on these boards, Bootguard may prevent modification. Is vendor-signed firmware, ME-minimized?

The best suggestion we can make is to sign up to our newsletter as this will be the first place any details relating to this will be released 🙂"|nitter
