[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.

[coreboot - Support #571] (New) Keyboard scan codes of HP Elitebook 2170p under coreboot are different with those under oem firmware.

Issue #571 has been reported by Wreg Yek. ---------------------------------------- Support #571: Keyboard scan codes of HP Elitebook 2170p under coreboot are different with those under oem firmware. https://ticket.coreboot.org/issues/571 * Author: Wreg Yek * Status: New * Priority: Normal * Target version: none * Start date: 2024-11-23 * Affected hardware: HP Elitebook 2170p * Affected OS: GNU/Linux with systemd v257-rc1 or later ---------------------------------------- HP Elitebook 2170p is weird compared with many other Elitebooks supported by coreboot, for its keyboard scan codes under coreboot is different with those under oem firmware, regardless of the same set of EC firmware blobs are used. The scan codes under oem firmware conform to the upstream [60-keyboard.hwdb](https://github.com/systemd/systemd/blob/main/hwdb.d/60-ke…, while after systemd v257-rc1, the `KEYBOARD_KEY_66=pickup_phone` within [upstream](https://github.com/systemd/systemd/commit/93b078c3dd40b10eed34a77… 60-keyboard.hwdb starts to conflict with the scan codes of backspace key under coreboot, where it is 0x66. Besides backspace, I have collected the scan codes of all Fn-keys under coreboot into the attached 61-2170p-kb.hwdb, which is adjusted to the default SMBIOS tables of coreboot for Elitebook 2170p, and could be used to walk around the scan code conflict. ---Files-------------------------------- 61-2170p-kb.hwdb (508 Bytes) -- You have received this notification because you have either subscribed to it, or are involved in it.
