Issue #461 has been updated by gaspar ilom.
The patch train got merged: https://review.coreboot.org/c/coreboot/+/81897/4
Anyway, in heads we have made an effort to use NRI on the W541 and T440p boards. However boot times are between 10 and 20s. So it seems like the mrc cache is not properly build and reused. Also, on the W541 S3 resume does not work (just reboots the machine).
I can offer testing and helping debugging this feature: https://github.com/linuxboot/heads/pull/1923
---------------------------------------- Feature #461: Replacing Haswell mrc.bin blob with free software https://ticket.coreboot.org/issues/461#change-1999
* Author: akjuxr3 akjuxr3 * Status: In Progress * Priority: Normal * Assignee: Angel Pons * Category: chipset configuration * Target version: none * Start date: 2020-04-01 * Related links: https://review.coreboot.org/q/topic:haswell-nri * Affected hardware: All Haswell mainboards ---------------------------------------- Currently in case of the ability to run as less amount of closed source software as possible and still have Microcode updates the reduced Intel ME with disabled bit in IFD and the lga1155 or the mobile versions of those cpus are the only option for x86_64 out there. The next cpu generation (Haswell) inside for example T440p and W541 require the binary blob mrc.bin
Are there any plans of replacing the Haswell mrc.bin with free software? Or have the x86_64 platform be given up when the goal is to run just free software and the people should move to aarch64 or risc-v?
