Dear u-boot list,

I recently compiled (latest: 2021.10) code of uboot as a boot loader for the Compute Module 3+ (Raspberry). Everything works fine except one issue: the IO from the storage is extreme slow. I read about issues in the past related to ext file systems. However the present issue relates to both ext and fat file systems so I assume its cause is different.

This is what I did:

U-Boot>   setenv pio_kernel "recovery/kernel.img"
U-Boot>   setenv pio_initrd "recovery/initrd.img"
U-Boot>   fatload mmc 0:1 ${kernel_addr_r} ${pio_kernel}
5299624 bytes read in 45262 ms (114.3 KiB/s)
U-Boot>   fatload mmc 0:1 ${ramdisk_addr_r} ${pio_initrd}
24239932 bytes read in 206978 ms (114.3 KiB/s)

The configuration of by build is attached.

Is there anyone else experiencing this kind of issues?

Thank you very much.

Mario

Vincent,

thank you very much. Applying the two patches mentioned in the series resolve the issues immediately.

Is it expected to have this enhancement in the upcoming u-boot release?

Cheers,
Mario

Are your patches still needed? If I read the comments on the issue it
was fixed in RPi firmware and your workaround is not needed, correct?

Ivan

I think this is a fair question.

The patches are still needed for certain tagged versions of the RPi firmware. 
Later tags may resolve this problem but may also introduce their own regressions which
force users back to a previous tag where this is a problem.

I think I would recommend including the patches so U-Boot works across all revisions of 
firmware and to future proof against subsequent changes in the clock API. 

Ultimately, I defer to the maintainers' choice.

Sorry, I missed your patch. I will test with your patch on today. 
I think that it's good to apply yours if there is no side-effect or any problem.
