Hi , I encounter some problem for ACPI
My ACPI table not loaded by initramfs.
I have three ACPI files follow below:

ACPI_TABLES ?= "spidev.asl mcu_thales.asl i2c3028.asl "
#ACPI_TABLES += " mcu_5g.asl i2c3028.asl "
ACPI_FEATURES_edison ?= "uart_2w i2c spi"

But the dmesg information is not show "load xxx.aml",which show the message below only:

root:~# dmesg | grep acpi
[    0.000000] Linux version 5.6.0-edison-acpi-standard (oe-user@oe-host) (gcc version 9.2.0 (GCC)) #1 SMP Tue Mar 2 01:46:52 UTC 2021

I currently use branch zeus with version "U-Boot 2020.10 " ,But I used branch zeus with version "U-Boot 2020.04 " before use the this version , I have not this issues and this ACPI is correctly.

Originally I used acpi to make rtc1 load faster than rtc0 ,but now rtc1 loads slower than rtc0

root:~# dmesg | grep rtc
[    3.050660] rtc_cmos 00:00: registered as rtc0
[    3.050883] rtc_cmos 00:00: no alarms, 242 bytes nvram
[    3.096086] hctosys: unable to open rtc device (rtc1)

In addition I can found ACPI table in system, but I think it not loaded.

root:/home/bovia/daemon# ls /sys/kernel/config/acpi/table/
i2c3028  mcu_thales  spidev

I don't know why this problem will happen, How about to solve it? Thank you!

Can you do dmesg | grep ACPI? I get:

But why is loading speed slow? Can let it be make faster?

I need to load faster than hctosys driver , because rtc is linked to rtc1,otherwise hctosys will failed.([ 3.096086] hctosys: unable to open rtc device (rtc1)) , Can you any idea solve it? Thank your help!

I think you mean earlier, not faster? All I can find is: https://bugzilla.kernel.org/show_bug.cgi?id=43010
i2c and spi only get loaded after acpi table is loaded. You can get the acpi tables loaded earlier by putting them in a cpio. But the bugzilla suggestion is to load hctosys later.

Yes, I mean earlier. Okay, I will try to use acpi-tables.cpio follow 1.3-ACPI-or-not.html#acpi-tables

Perform the follow stepping :

  • bitbake -c cleansstate acpi-tables
  • bitbake acpi-tables
  • make edison-image
 $ ls out/current/build/tmp/deploy/images/edison/acpi-tables.cpio
out/current/build/tmp/deploy/images/edison/acpi-tables.cpio
  • Preloading by U-Boot
  • Modify meta-intel-edison/meta-intel-edison-bsp/recipes-bsp/u-boot/files/edison.env
  • load_edsboot=load mmc 1 ${loadaddr} /boot/bzImage;load mmc 1 ${rdaddr} acpi-tables.cpio;load mmc 1 ${rdaddr} /boot/initrd instead of load_edsboot=load mmc 1 ${loadaddr} /boot/bzImage;load mmc 1 ${rdaddr} /boot/initrd

I have performed above step , but the ACPI table was not loaded earlier.
Maybe I am missing some steps? because original load_edsboot is 'load mmc 0:9 0x100000 vmlinuz.efi; load mmc 0:9 0x3000000 acpi-tables.cpio' in 1.3-ACPI-or-not.html#acpi-tables

If you want to see if the acpi tables are loaded earlier, go into the rescue image (run do_rescue). Normally tables are loaded from the file system (so after mounting), but when loaded by U-Boot they are loaded before.

But I wouldn't be surprised if it doesn't help you. I would bet on making hctosys a module and loading that later.

I also tried to making hctosys and loading that later.

But it's a little hard for me that making hctosys a module or find out who performing hctosys.

The munuconfig don't let me select to <M> at CONFIG_RTC_HCTOSYS and CONFIG_RTC_CLASS

  │ │                     (rtc1)  RTC used to set the system time

And also not found these in system

Thank your help!
I have found the this patch support hctosys from modular RTC drivers

It is help for me.
It seem that the problem has been solved in the kernel 5.7 and above.

So I you try the Dunfell image now in PR #126 which has 5.10.24 LTS kernel this patch should be already present.
