From cc9876a374db2515cefc1e3a3a1745d643b19554 Mon Sep 17 00:00:00 2001 From: Mate Kukri Date: Mon, 2 Dec 2024 01:36:35 +0000 Subject: [PATCH 8/9] mb/lenovo: Add ThinkPad T480 This machine has BootGuard fused and requires deguard to boot coreboot. Works: - Intel GPU - Internal screen - Ethernet - USB - EC + Fan control + Keyboard + Both batteries + Charging via both Type-C ports + Debug UART - WLAN card: + WiFi works + Bluetooth works - M.2 main SSD - Speakers, headphone jack - S3 sleep Known issues: - Alpine Ridge Thunderbolt 3 controller does not work - Missing HDA verbs, audio still works - Function keys are handled differently from stock firmware + These should inject XF86 keycodes instead of directly controlling, volume, brightness, etc in hardware. - Nvidia dGPU - Needs option ROM - Power enable code is buggy - Nouveau only works on linux 6.8-6.9 Untested (should work): - SATA main SSD - WWAN slot + PCIe x2 NVME drive + WWAN card (bus) - SD reader (USB) - Webcam (USB) - External video outputs Signed-off-by: Mate Kukri Change-Id: I19d421412c771c1f242f6ff39453f824fa866163 --- src/device/pci_rom.c | 12 +- src/ec/lenovo/h8/acpi/ec.asl | 2 +- src/ec/lenovo/h8/bluetooth.c | 12 +- src/ec/lenovo/h8/wwan.c | 12 +- src/mainboard/lenovo/sklkbl_thinkpad/Kconfig | 39 +++- .../lenovo/sklkbl_thinkpad/Kconfig.name | 6 + .../lenovo/sklkbl_thinkpad/Makefile.mk | 8 +- .../lenovo/sklkbl_thinkpad/acpi/ec.asl | 13 +- .../lenovo/sklkbl_thinkpad/bootblock.c | 50 +++++ .../lenovo/sklkbl_thinkpad/devicetree.cb | 36 ++++ src/mainboard/lenovo/sklkbl_thinkpad/dsdt.asl | 17 +- src/mainboard/lenovo/sklkbl_thinkpad/ec.c | 153 +++++++++++++ src/mainboard/lenovo/sklkbl_thinkpad/ec.h | 99 +++++++++ src/mainboard/lenovo/sklkbl_thinkpad/gpio.h | 8 + .../lenovo/sklkbl_thinkpad/ramstage.c | 98 ++++++++- .../lenovo/sklkbl_thinkpad/romstage.c | 24 +++ .../sklkbl_thinkpad/variants/t480/data.vbt | Bin 0 -> 4106 bytes .../variants/t480/gma-mainboard.ads | 19 ++ .../sklkbl_thinkpad/variants/t480/gpio.c | 203 ++++++++++++++++++ .../sklkbl_thinkpad/variants/t480/hda_verb.c | 10 + .../variants/t480/overridetree.cb | 124 +++++++++++ .../variants/t480s/gma-mainboard.ads | 15 ++ .../sklkbl_thinkpad/variants/t480s/gpio.c | 199 +++++++++++++++++ .../sklkbl_thinkpad/variants/t480s/hda_verb.c | 10 + .../variants/t480s/overridetree.cb | 121 +++++++++++ 25 files changed, 1258 insertions(+), 32 deletions(-) create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/ec.c create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/ec.h create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/gpio.h create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/variants/t480/data.vbt create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/variants/t480/gma-mainboard.ads create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/variants/t480/gpio.c create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/variants/t480/hda_verb.c create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/variants/t480/overridetree.cb create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/variants/t480s/gma-mainboard.ads create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/variants/t480s/gpio.c create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/variants/t480s/hda_verb.c create mode 100644 src/mainboard/lenovo/sklkbl_thinkpad/variants/t480s/overridetree.cb diff --git a/src/device/pci_rom.c b/src/device/pci_rom.c index d60720eb49..b18dfdd287 100644 --- a/src/device/pci_rom.c +++ b/src/device/pci_rom.c @@ -304,11 +304,11 @@ void pci_rom_ssdt(const struct device *device) return; } - const char *scope = acpi_device_path(device); - if (!scope) { - printk(BIOS_ERR, "%s: Missing ACPI scope\n", dev_path(device)); - return; - } + // const char *scope = acpi_device_path(device); + // if (!scope) { + // printk(BIOS_ERR, "%s: Missing ACPI scope\n", dev_path(device)); + // return; + // } /* Supports up to four devices. */ if ((CBMEM_ID_ROM0 + ngfx) > CBMEM_ID_ROM3) { @@ -336,7 +336,7 @@ void pci_rom_ssdt(const struct device *device) memcpy(cbrom, rom, cbrom_length); /* write _ROM method */ - acpigen_write_scope(scope); + acpigen_write_scope("\\_SB.PCI0.RP01.PEGP"); acpigen_write_rom(cbrom, cbrom_length); acpigen_pop_len(); /* pop scope */ } diff --git a/src/ec/lenovo/h8/acpi/ec.asl b/src/ec/lenovo/h8/acpi/ec.asl index bc54d3b422..8f4a8e1986 100644 --- a/src/ec/lenovo/h8/acpi/ec.asl +++ b/src/ec/lenovo/h8/acpi/ec.asl @@ -331,7 +331,7 @@ Device(EC) #include "sleepbutton.asl" #include "lid.asl" #include "beep.asl" -#include "thermal.asl" +//#include "thermal.asl" #include "systemstatus.asl" #include "thinkpad.asl" } diff --git a/src/ec/lenovo/h8/bluetooth.c b/src/ec/lenovo/h8/bluetooth.c index 16fc8dce39..ef4f6ad1f5 100644 --- a/src/ec/lenovo/h8/bluetooth.c +++ b/src/ec/lenovo/h8/bluetooth.c @@ -1,6 +1,6 @@ /* SPDX-License-Identifier: GPL-2.0-only */ -#include +// #include #include #include #include @@ -28,16 +28,16 @@ bool h8_has_bdc(const struct device *dev) { struct ec_lenovo_h8_config *conf = dev->chip_info; - if (!conf->has_bdc_detection) { + if (1 || !conf->has_bdc_detection) { printk(BIOS_INFO, "H8: BDC detection not implemented.
