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 too much code together, without actually managing to work together on a product. Beside names, I tried to keep everything as usual. There's a wiki (slowly filled with contents from the old one) https://flashprog.org/ an IRC channel #flashprog on libera.chat and a mailing list, of course flashprog(a)flashprog.org managed at https://mail.sourcearcade.org/postorius/lists/flashprog.flashprog.org/ Review continues on a Gerrit instance, albeit on https://review.sourcearcade.org/ And you can clone the repository from a GitHub mirror https://github.com/SourceArcade/flashprog.git Now that all this is done, I hope to return to work on the source code again. There are still many patches open that were pending for flashrom-stable. And it looks like the next release candidate is only one commit away :) So stay tuned!

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 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. I don't think we're interested in > tracking this as a Feature Request here. During startup this reset delay should not hold up the boot, should it? 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.

[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…
