[coreboot - Feature #433] (New) Unify TPM drivers in coreboot
by Michał Żygowski Sept. 7, 2025

Sept. 7, 2025

Issue #433 has been reported by Michał Żygowski. ---------------------------------------- Feature #433: Unify TPM drivers in coreboot https://ticket.coreboot.org/issues/433 * Author: Michał Żygowski * Status: New * Priority: Normal * Target version: none * Start date: 2022-10-24 ---------------------------------------- Add an option to compile all drivers for TPM 1.2, 2.0 TIS and CRB. The motivation is to not build multiple coreboot ROMs for each possible TPM supported by the platform. The tasks would include: - runtime TPM detection (probing TPM_INTF_CAPABILITY and TPM_INTERFACE_ID) - rename the TPM driver functions, make them static and expose them as a driver structure, e.g. struct tpm_driver { void (*init)(void); int (*open)(void); int (*close)(void); int (*sendrecv)(const uint8_t *sendbuf, size_t send_size, uint8_t *recvbuf, size_t *recv_len); } - based on the detected TPM, hook the tpm_driver functions to provide the global TPM API: tis_open, tis_close, tis_init, tis_sendrecv. Some additional API to get vendor/device name could also be considered. -- You have received this notification because you have either subscribed to it, or are involved in it.

[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.

Issue #535 has been reported by frantic from xboot. ---------------------------------------- Bug #535: T420: Power light stays off after reboot https://ticket.coreboot.org/issues/535 * Author: frantic from xboot * Status: New * Priority: Low * Target version: master * Start date: 2024-04-24 * Affected hardware: Lenovo ThinkPad T420 ---------------------------------------- I have recently encountered a bug in coreboot where if you reboot the computer, the keyboard power light will stay turned off after it turns back on. Where if you do a clean boot, the light turns on. I am unsure whether this is a coreboot or payload issue. I am using GRUB as my payload. Just run the `reboot` command in Linux and it should be reproducible. Priority set to `Low` as it doesn't affect usability all too much. -- You have received this notification because you have either subscribed to it, or are involved in it.

Issue #552 has been reported by Maya Matuszczyk. ---------------------------------------- Bug #552: X201 not booting with edk2 payload https://ticket.coreboot.org/issues/552 * Author: Maya Matuszczyk * Status: New * Priority: Normal * Category: board support * Target version: none * Start date: 2024-08-18 * Affected hardware: x201 ---------------------------------------- Hello, I tried to update my x201 with a new version of coreboot(I lost the working one). After building(using default config + set to x201 + bigger cbfs + linear high-res framebuffer) with latest release I couldn't get anything with edk2 to boot on it. I've tried changing `RESOURCE_ALLOCATION_TOP_DOWN` and using newer/older tags of MrChromebox's edk2 fork. -- You have received this notification because you have either subscribed to it, or are involved in it.

[coreboot - Bug #548] (New) Computer Fails To Recognize Upgraded WiFi Card

Issue #548 has been reported by Jeremy Brown. ---------------------------------------- Bug #548: Computer Fails To Recognize Upgraded WiFi Card https://ticket.coreboot.org/issues/548 * Author: Jeremy Brown * Status: New * Priority: Normal * Target version: none * Start date: 2024-07-15 ---------------------------------------- I am running coreboot 24.05 on my Lenovo X201. I decided to upgrade my WiFi card from an Intel Centrino Advanced-N 6205 to an Intel Wireless-AC 7260; since I selected the option to support Intel PCIe cards in my build config I expected everything to work but my computer fails to recognize the new card. The old card is still recognized if I reinstall it so I know I didn't mess up the socket somehow; I've read reports of the 7260 [working with a modded factory BIOS](https://richbits.rbarnes.org/installing-the-intel-7260-in-the-thinkpa… so I don't think there's an electrical issue. I've attached lspci data from both chips, lmk if additional information is needed. ---Files-------------------------------- 6205_lspci_tree.txt (1.63 KB) 7260_lspci_tree.txt (1.57 KB) 6205_lspci.txt (12.8 KB) 7260_lspci.txt (12.2 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.

Re: PC with coreboot - boot menu locked

Dear Andrea, Welcome to coreboot. Please do not send messages over 500 kB (definitely not more than 1 MB) to mailing lists.

SeaBIOS (version SageBIOS-20161017_085144-ttyree-dev-gtk-gtech-com) Select boot device: 1. Payload [igt_secure] Sage Engineering [1] *was* a company offering coreboot development a long time ago. No idea, if they upstreamed this board, or how to get the source code. What board is it exactly? Anyway, your attached dump has a coreboot image (CBFS – coreboot file system), you can dump with `cbfstool`: ``` $ ~/src/coreboot/util/cbfstool/cbfstool bios_igt_orig.bin print FMAP REGION: COREBOOT bios_igt_orig.bin: 16384 kB, bootblocksize 1024, romsize 16777216, offset 0xc00000 alignment: 64 bytes, architecture: x86 Name Offset Type Size Comp roothashes 0xc00000 (unknown) 192 none fallback/romstage 0xc00100 stage 60241 none fallback/ramstage 0xc0ecc0 stage 94548 none fallback/payload 0xc25e80 simple elf 49158 none bootsplash.jpg 0xc31ec0 bootsplash 48411 none etc/boot-menu-wait 0xc3dc40 raw 8 none (empty) 0xc3dc80 null 4888 none keyupdate 0xc3efc0 mma 8192 none (empty) 0xc41000 null 3992 none keystore 0xc41fc0 mrc 131072 none img/igt_secure 0xc62000 simple elf 83362 none vgaroms/videobios.rom 0xc76600 optionrom 65536 none (empty) 0xc86640 null 51544 none bootorder 0xc92fc0 raw 4096 none (empty) 0xc94000 null 2604952 none cpu_microcode_blob.bin 0xf0ffc0 microcode 38912 none (empty) 0xf19800 null 157592 none mrc.cache 0xf3ffc0 mrc_cache 65536 none (empty) 0xf50000 null 65432 none fsp.bin 0xf5ffc0 spd 524288 none (empty) 0xfe0000 null 12248 none bootorder_sata 0xfe3000 raw 4096 none bootorder_usb 0xfe4040 raw 4096 none bootorder_sec 0xfe5080 raw 4096 none (empty) 0xfe60c0 null 24 none rootpub 0xfe6100 fsp 2064 none (empty) 0xfe6940 null 103000 none ``` It does not seem to contain the build configuration, but you might be able to boot from a USB device. From there you should be able to read the logs with `cbmem` and find out the coreboot version and board name. Maybe that brings you further. I have never heard of `igt_secure`. As you can access the dump, you can at least build the payload yourself, and replace `fallback/payload` or add it under `img/`. Maybe that works. No idea if the keys/hashes verify anything from this. Anyway, the above should get you going. Kind regards, Paul [1]: https://se-eng.com/ [2]:

[p8x7x port] Realtek loses its mind & Marvell not going with times.
by Keith Hui Feb. 28, 2025

Feb. 28, 2025

(Catchy subject eh? There's some truth to both.) My coreboot port to Asus P8Z77-V LE PLUS is almost ready, but I still have two outstanding problems. The board is losing its MAC address, partly because it doesn't have an EEPROM for vital product data. I enabled the rtl8168 driver in coreboot so I can configure the LEDs and MAC address. Lights work great, but the MAC address always revert to 00:00:00:00:00:05 by the time Linux kernel sees it. I would then have to reassign its proper MAC address using "ip link change eno0 address <mac>". I added a debug read back in the rtl81xx driver and the device appears to be taking the MAC I programmed. Board also has a Marvell 88SE9120 for two extra SATA ports. It came up in legacy mode and pata_marvell driver isn't able to operate it. I find no documentation on how to switch to AHCI mode like ASM1061. Needless to say those two ports are currently useless. Ideas? I'm hoping to get this and a few supporting patches in for next release. https://review.coreboot.org/c/coreboot/+/86172 Thanks Keith
