Baytrail issue to communicate with superios.
by Jose Trujillo 06 Dec '23

06 Dec '23

Hello All: I hope you are doing great. The system: Baytrail E3845, 4GB DDR3, fintek (f81803a) @0x4e and Winbond (w83627dhg) @0x2e, etc... I just built coreboot (master) the last few days, everything works wonderfully except 2 things: - Libgfxinit probably because this board is using the AUX channel instead DDI to communicate with the monitors; seems to me libgfxinit cannot find monitors thru DP ports but I could be wrong because neither VGA gets initialized; and eventually Linux always … [View More]

Announcement: flashrom-stable continues as flashprog
by Nico Huber 06 Dec '23

06 Dec '23

Hi everybody! as you may know already, flashrom-stable was removed from review.coreboot.org a while ago. flashrom-stable was a short- lived semi-fork, based on flashrom v1.2 [1]. The effort to keep developing a stable flash programming tool for everyone, however, shall continue. I have hence renamed flashrom-stable to *flashprog*. Now it's definitely a fork. The main reason for the fork is that I saw the flashrom master (now main) branch to become unmaintainable. Probably because we merged … [View More]

Linux boot delayed by value of generic.reset_off_delay_ms (touchscreen reset)?
by Paul Menzel 05 Dec '23

05 Dec '23

Dear coreboot folks, On the Dell Latitude 5430 Chromebook (google/brya/var/crota) there is a delay of 160 ms during startup in the Linux kernel [1]: [ 0.000000] microcode: microcode updated early to revision 0x430, date = 2023-06-07 [ 0.000000] Linux version 5.15.124-20281-g306376f9e9db (chrome-bot@chromeos-release-builder-us-central1-c-x32-9-oel9) (Chromium OS 17.0_pre496208_p20230501-r16 clang version 17.0.0 (/mnt/host/source/src/third_party/llvm-project … [View More]98f5a340975bc00197c57e39eb4ca26e2da0e8a2), LLD 17.0.0) #1 SMP PREEMPT Mon Oct 2 18:31:36 PDT 2023 […] [ 0.150271] ACPI: PM: Power Resource [PR00] [ 0.313289] ACPI: PM: Power Resource [PR01] A @google.com person commented, that this *could* be caused by the reset delay of the ELAN touchscreen. From `src/third_party/coreboot/src/mainboard/google/brya/variants/crota/overridetree.cb`: device ref i2c3 on chip drivers/i2c/hid register "generic.hid" = ""ELAN900C"" register "generic.desc" = ""ELAN Touchscreen"" register "generic.irq" = "ACPI_IRQ_LEVEL_LOW(GPP_C7_IRQ)" register "generic.detect" = "1" register "generic.reset_gpio" = "ACPI_GPIO_OUTPUT_ACTIVE_LOW(GPP_C1)" register "generic.reset_delay_ms" = "150" register "generic.reset_off_delay_ms" = "1" register "generic.enable_gpio" = "ACPI_GPIO_OUTPUT_ACTIVE_HIGH(GPP_C0)" register "generic.enable_delay_ms" = "6" register "generic.stop_gpio" = "ACPI_GPIO_OUTPUT_ACTIVE_LOW(GPP_C6)" register "generic.stop_off_delay_ms" = "1" register "generic.has_power_resource" = "1" register "hid_desc_reg_offset" = "0x01" device i2c 0x16 on end end end As I have been bitten the last time, I tried to flash a Dell Chromebook, I am weary to test, so I am asking here. > The delay is unavoidable, although I suppose there's room for > improvement on making ACPI power sequencing parallelizable or > otherwise deferring it until the device is actually getting probed > (preferably using asynchronous probe, since this is a slow device -- > ChromeOS tends to configure touchscreen drivers for async probe > already, or else loaded as modules). > > Perhaps you can take this problem upstream if you'd like to work on > something, but from a ChromeOS perspective this is either Intended > Behavior or a Feature Request.

Could the firmware reset the touchscreen, and somehow message the OS, that it’s not needed anymore? Kind regards, Paul [1]: https://issuetracker.google.com/issues/303565666 PS: I was unable to change the issue title to correct PR01 to PR00. [View Less]

[RFH] board-status: Please upload your logs
by Paul Menzel 03 Dec '23

03 Dec '23

Dear coreboot folks, especially users, Uploads to the board status repository [1] have ceased quite a bit this year. As most community members only have access to a few devices, these logs are tremendously useful to support users, and to analyze bugs and regressions. So, just a quick shout-out to you all to quickly take the time to upload the log files [2]. Kind regards, Paul [1]: https://review.coreboot.org/plugins/gitiles/board-status/ [2]: https://review.coreboot.org/plugins/gitiles/coreboot/+/refs/heads/master/ut…
