All,

As of Friday of last week, Dmitry has completed his work on the CPR-GFX. He is currently investigating issues during power up of the GPU, where GPU clocks sometimes fail to start.

At the moment I do not have a full accounting of Dmitry's time spent on the project for last week, but I will forward that in future updates as soon as I have it.

I spent 0 hours on the project last week as I was out of office on holiday.

As always, if you have any questions or concerns please let me know.

Hi Dmitry,

After building, I power cycled 10 or so times and it does always boot 😊 The boot is pretty slow (2+minutues). Is this normal? Seems like it gets stuck twice on boot up:

The long boot time is expected for now, as the SoC is booting at 300 Mhz. But not _that_ long.

You can try changing this by selecting other CONFIG_CPU_FREQ_DEFAULT. For example CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL=y (and _DEFAULT_GOV_POWERSAVE=n).

Please disable the CONFIG_FW_LOADER_USER_HELPER option, unless you require it for some reason.

But also note that the firmware file seems to be missing from your initramfs. I have uploaded the initramfs with all firmware file to [1], please concatenate it to your gzipped initramfs if you use any or just use it as an initramfs.

Note, the image is big, as it contains adsp firmware. We can remove the aDSP firmware later.

Hi Dmitry,

We use these instructions (with change to compiler version) to build a kernel and boot image: https://www.96boards.org/documentation/consumer/dragonboard/dragonboard820c/...

A ramdisk image is used in the above.

I did try some of the suggestions but there is no change to the boot time. I think, in the end, what we need are instructions similar to the instructions in the above link that we can both follow to get the same results.

Thanks,

Kim

Hi Dmitry,

I'm not sure how to know if I need the initramfs update and how to use the file in the link.

As for the CONFIGs, I currently have these (before trying your suggestions): CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y # CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set # CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL is not set And CONFIG_FW_LOADER=y CONFIG_FIRMWARE_IN_KERNEL=y CONFIG_EXTRA_FIRMWARE="" # CONFIG_FW_LOADER_USER_HELPER_FALLBACK is not set

I will try changing the performance governor from ondemand to schedutil as you suggest. And also I can try Nicolas's suggestions.

Hi Dmitry,

I'm not sure how to know if I need the initramfs update and how to use the file in the link.

As for the CONFIGs, I currently have these (before trying your suggestions): CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y # CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set # CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL is not set And CONFIG_FW_LOADER=y CONFIG_FIRMWARE_IN_KERNEL=y CONFIG_EXTRA_FIRMWARE="" # CONFIG_FW_LOADER_USER_HELPER_FALLBACK is not set

I will try changing the performance governor from ondemand to schedutil as you suggest. And also I can try Nicolas's suggestions.

Thanks, Kim

Hi Dmitry,

After building, I power cycled 10 or so times and it does always boot 😊 The boot is pretty slow (2+minutues). Is this normal? Seems like it gets stuck twice on boot up:

The long boot time is expected for now, as the SoC is booting at 300 Mhz. But not _that_ long.

You can try changing this by selecting other CONFIG_CPU_FREQ_DEFAULT. For example CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL=y (and _DEFAULT_GOV_POWERSAVE=n).

Please disable the CONFIG_FW_LOADER_USER_HELPER option, unless you require it for some reason.

But also note that the firmware file seems to be missing from your initramfs. I have uploaded the initramfs with all firmware file to [1], please concatenate it to your gzipped initramfs if you use any or just use it as an initramfs.

Note, the image is big, as it contains adsp firmware. We can remove the aDSP firmware later.

 All,

 As of Friday of last week, Dmitry has completed his work on the
 CPR-GFX. He is currently investigating issues during power up of the
 GPU, where GPU clocks sometimes fail to start.

 At the moment I do not have a full accounting of Dmitry's time spent
 on the project for last week, but I will forward that in future
 updates as soon as I have it.

 I spent 0 hours on the project last week as I was out of office on
 holiday.

 As always, if you have any questions or concerns please let me know.

 Paul

Hi Dmitry,

I built the image with '--ramdisk initramfs-firmware-dragonboard820c-image-qcom-armv8a.cpio' . When I try to flash, it reports that the image built is too large (75M) to flash:

#slroot @ ~/git_linaro_5.15 host> fastboot.exe flash boot boot-5.15.0-qcomlt-arm64.img target reported max download size of 536870912 bytes sending 'boot' (76464 KB)... OKAY [ 2.585s] writing 'boot'... FAILED (remote: size too large) finished. total time: 2.607s

Hi Dmitry,

To be clear, do I run the mkbootimg tool with '--ramdisk initramfs-firmware-dragonboard820c-image-qcom-armv8a.cpio' ?

Yes. This is how e.g. I test the kernel with the Debian rootfs here.

Hi Dmitry,

We use these instructions (with change to compiler version) to build a kernel and boot image: https://www.96boards.org/documentation/consumer/dragonboard/dragonboa r d820c/build/linux-kernel.md.html

A ramdisk image is used in the above.

I did try some of the suggestions but there is no change to the boot time. I think, in the end, what we need are instructions similar to the instructions in the above link that we can both follow to get the same results.

I did some test with different initrd images. Please use the initramfs file that I have provided to you instead of the image pointed on the webpage.
