[coreboot - Feature #461] (In Progress) Replacing Haswell mrc.bin blob with free software
by Angel Pons 23 May '24

23 May '24

Issue #461 has been updated by Angel Pons. Category changed from board support to chipset configuration Status changed from New to In Progress Start date changed from 02/16/2023 to 04/01/2020 % Done changed from 0 to 30 Related links updated Affected hardware changed from T440p and other to All Haswell mainboards # Current state of the meme magic (Haswell NRI) ## Done - Native non-raminit stuff (already submitted): needed for 9-series boards with Broadwell MRC.bin e.g. https://review.coreboot.org/68188 - Bare minimum memory initialisation (just enough meme magic to be able to boot): patch train up until https://review.coreboot.org/64198 - S3 suspend/resume and fast boot support: https://review.coreboot.org/81897 - Sense amplifier offset training: https://review.coreboot.org/81948 ## Implemented internally in the giant bowl of spaghetti, but in need to clean up the code before publishing - 1D margin centering algorithms (used for various training steps) - Setting non-training command rate (to 1N or 2N, we currently remain at 3T) and LCT (Late Command Training) - 2D margin centering algorithms (used for various training steps) - Power training (optimisation meme magic to reduce power consumption) - TAT (Turnaround Training, a performance improvement) - The raminit console (a half-arsed thing that allows playing around with settings over UART/usbdebug) ## Not implemented or not working yet - Broadwell support (I once got a Broadwell ULT system to boot without MRC, but I had to commit unspeakable horrors to the already messy codebase) - Properly programming some registers about DIMM energy (doesn't seem to be required, but the logic to program these is horribly convoluted and I haven't felt like figuring out how it works) - Automatic overclocking support (will require redesigning how the MPLL handling works, because it currently stinks) # TL;DR - With what's currently submitted, choosing Haswell NRI in menuconfig **WILL NOT BOOT**. It says "NOT WORKING" in the prompt. - Current top of tree (what you should use if you want to try Haswell NRI) is https://review.coreboot.org/81948 - With the aforementioned changes from Gerrit, booting should work. S3 resume should also work, but please test in advance. - **BACK UP YOUR STUFF!** I will NOT be held responsible by any data losses arising from the use of the current state of Haswell NRI. - Because not all training steps are ready yet, performance and power consumption are not optimal. Fix is to finish upstreaming them. - Also, do NOT try to overclock the RAM under any circumstances. You will only make your system much more unstable for no reason. ---------------------------------------- Feature #461: Replacing Haswell mrc.bin blob with free software https://ticket.coreboot.org/issues/461#change-1854 * 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?

[coreboot - Feature #540] (New) Support for Lenovo ThinkPad X250 - the competitor to the shortly added HP EliteBook 820 G2

Issue #540 has been reported by akjuxr3 akjuxr3. ---------------------------------------- Feature #540: Support for Lenovo ThinkPad X250 - the competitor to the shortly added HP EliteBook 820 G2 https://ticket.coreboot.org/issues/540 * Author: akjuxr3 akjuxr3 * Status: New * Priority: Normal * Category: board support * Target version: none * Start date: 2024-05-22 * Affected hardware: Lenovo Thinkpad X250 ---------------------------------------- Coreboot now have support for the HP EliteBook 820 G2. This is great, but sadly the keyboard is for a person using Thinkpad keyboards forever not usable. The Thinkpad X250 is the competitor to the HP EliteBook 820 G2. https://www.notebookcheck.net/Face-Off-HP-EliteBook-820-G2-vs-Lenovo-ThinkP… The X250 also have a Full-HD IPS screen. This would also fix the problems many people have with the X230 and spend much time and effort to get a Full-HD IPS screen running in the X230. Nico Huber have(had?) such a X250: https://review.coreboot.org/c/coreboot/+/23820/7#message-04cf9f804c1292f457… Other coreboot developer also seem to have a X250: https://review.coreboot.org/c/coreboot/+/51179 Have someone taken a deeper look into the Thinkpad X250? Is there something special why suddenly the HP EliteBook 820 G2 got supported instead of a typical Thinkpad like it was the case for years at coreboot? -- You have received this notification because you have either subscribed to it, or are involved in it.

Category set to board support Assignee set to Angel Pons Affected hardware set to T440p and other > Already being worked on, refer to https://review.coreboot.org/q/topic:haswell-nri Great to see active work on this. Lets hope it get merged soon.

[coreboot - Bug #538] (New) [Soft Brick] x230 Dock Causes Internal Display to "Permanently" Malfunction

Issue #538 has been reported by Brian L. ---------------------------------------- Bug #538: [Soft Brick] x230 Dock Causes Internal Display to "Permanently" Malfunction https://ticket.coreboot.org/issues/538 * Author: Brian L * Status: New * Priority: High * Target version: none * Start date: 2024-05-14 * Affected hardware: Lenovo x230 ---------------------------------------- Environment: - Lenovo x230 - Stock screen replaced with Pixel Qi (not sure if relevant) (plug & play LVDS) - Coreboot using Heads (coreboot + linuxboot) - Official lenovo docking station connected to external monitor via DisplayPort Bug Trigger: Using Heads/coreboot fine for years with my Pixel Qi screen modded x230. I then bought a Lenovo docking station. Booted up, everything worked fine. Disconnected from dock, booted up, and there was no bios screen. Screen did not turn on until taken over by Linux Kernel. Once in userspace, wayland could no longer identify the monitor as a Pixel Qi or its proper resolution. EDID is blank. Booting with docking station allows bios to show on external display. Restarting did *not* fix the issue, reflashing heads did *not* fix the issue, flashing skulls (coreboot + seabios) did *not* fix the issue. Flashing stock bios *did fix* the issue. I can now see BIOS screen and get proper EDID in userspace whether on the dock or not. *However* reflashing coreboot again, even coming from stock bios working state, and I immediately now no longer get a BIOS screen or EDID, even without ever introducing the dock again. Essentially now bricked with anything but stock bios. -- You have received this notification because you have either subscribed to it, or are involved in it.

Micron e.MMC Memory(MTFC64GAPALBH-IT) is not detected
by Murali Ayyappan 21 May '24

21 May '24

Hi, Our custom board is designed based on Denverton SOC. The used boot loader is coreboot-4.13 version and Linux kernel 5.10.30 version. In our design, the eMMC interface is used, and connected Micron e.MMC memory(MTFC64GAPALBH-IT) to it. The eMMC is enabled in coreboot device tree file. Here's the snippet from ./src/mainboard/intel/harcuvar/devicetree.cb file. device pci 1a.2 on end # UART 2 device pci 1c.0 on end # eMMC device pci 1f.0 on end # LPC bridge device pci 1f.2 on end # PMC/ACPI and, in linux kernel following kernel modules are enabled for host controller, # MMC/SD/SDIO Host Controller Drivers # # CONFIG_MMC_DEBUG is not set CONFIG_MMC_SDHCI=y CONFIG_MMC_SDHCI_IO_ACCESSORS=y CONFIG_MMC_SDHCI_PCI=y CONFIG_MMC_RICOH_MMC=y CONFIG_MMC_SDHCI_ACPI=y # CONFIG_MMC_SDHCI_PLTFM is not set # CONFIG_MMC_WBSD is not set # CONFIG_MMC_TIFM_SD is not set # CONFIG_MMC_SPI is not set # CONFIG_MMC_CB710 is not set # CONFIG_MMC_VIA_SDMMC is not set # CONFIG_MMC_VUB300 is not set # CONFIG_MMC_USHC is not set # CONFIG_MMC_USDHI6ROL0 is not set CONFIG_MMC_CQHCI=y and for memory device enabled following kernel modules, CONFIG_MMC=y CONFIG_PWRSEQ_EMMC=y CONFIG_PWRSEQ_SIMPLE=y CONFIG_MMC_BLOCK=y CONFIG_MMC_BLOCK_MINORS=8 Per SOC datasheet the host controller is seen in Bus 0, Device 28 and Function 0 in PCI bus, but the connected memory is not detected under this controller. when added debug prints in linux kernel driver source files, found that the mmc_rescan( ) function is failing due to mmc_attach failing with errno -110. Thanks, Murali

I've just enabled Gitiles again. We will observe which effect this has on Gerrit now. Fingers crossing that it won't cause a high load anymore :) Felix
